Much of the prior research reflects a biological or medical perspective on human sexuality. It assumes that as people age, physical changes, hormonal changes, or chronic illnesses reduce or eliminate sexual desire and sexual behavior sexual behavior A person's sexual practices–ie, whether he/she engages in heterosexual or homosexual activity. See Sex life, Sexual life. . This literature reflects the general trend toward the medicalization medicalization Social medicine A term for the erroneous tendency by society–often perpetuated by health professionals–to view effects of socioeconomic disadvantage as purely medical issues of human sexual functioning, which has accelerated in the past 20 years (Tiefer, 2004). It overlooks psychological and social influences on sexuality.
A Biopsychosocial Perspective
In contrast, what is needed is a biopsychosocial perspective, one that combines biological, psychological, and socio-environmental factors (DeLamater, 2002). Any approach to the study of human sexuality that stresses only one dimension, such as biology or sociology, is counterproductive (Rossi, 1994). This paper applies such a model to the understanding of sexual desire in women and men over the age of 45. The components of the model are listed in Figure 1.
Figure 1. Biopsychosocial Model of Sexuality Biological Influences Hormonal system Vascular system Illness/treatment Psychological Influences Sexual information Attitudes toward sexual expression Mental Health Depression/Treatment Social Influences Availability of a partner Length of relationship Quality of relationship Income
Among the biological influences are the hormonal and vascular systems and illnesses and associated treatments. Important psychological influences include sexual information, sexual attitudes, and mental health. Within the category of relational influences, the availability of a partner is a prerequisite for partnered sexual activity. Income is also relevant as an index of access to resources related to health, such as living standard.
We believe that biological factors provide a necessary but not sufficient condition for sexual functioning. In addition to biological capability, the person must have knowledge and attitudes supportive of sexual activity. The availability of a partner also influences sexual expression.
The purpose of this study is to examine how levels of sexual desire are associated with these biopsychosocial factors. We first discuss sexual desire. Next, we review the literature on the relationship between the biospychosocial influences and sexual desire. Then we will present data from a survey of a representative sample of 1,384 persons age 45 or older. The variables in our analyses include age, illnesses, and medication use; attitudes, expectations, and knowledge; and presence or absence of a sexual partner, education and household income. In particular, we wanted to determine whether sexual desire declines with age, and, if it does, identify which of these factors are the main influences. We are especially interested in the impact of attitudes, which reflect the influence of cultural values and stereotypes.
There is no universally accepted definition of sexual desire. Often it is confused with other aspects of human sexuality. In fact, sexual desire can be associated with sexual behavior but is simultaneously separate from it.
Theorists and researchers in the area of sexual desire have used two main frameworks. The first and most common assumes that sexual desire is an innate motivational force (i.e., an instinct, drive, need, urge, appetite, wish, or want). The second framework emphasizes the relational aspects of sexual desire, conceptualizing desire as one factor in a larger relational context.
As early as 1886, von Krafft-Ebing (1886/1965) discussed sexual desire as a powerful "physiological law" that arose jointly from cerebral activity (e.g., using the imagination) and the pleasurable physical sensations associated with this cerebral activity. Freud, too, conceived of sexual desire as a biological fact, an innate, motivational force. Following in their footsteps, Kaplan (1977, 1979) stated that sexual desire is an appetite or drive that motivates us to engage in sexual behavior. Like other drives, such as hunger, sexual desire is regulated by the avoidance of pain and the seeking of pleasure, and it is produced by the activation of a specific neural system in the brain.
Other researchers choose to define sexual desire not as a biological force but as a cognitive or emotional experience, such as wishing or longing (Everaerd, 1988; Schreiner-Engel, Schiavi, White, & Ghizzani, 1989). According to according to
1. As stated or indicated by; on the authority of: according to historians.
2. In keeping with: according to instructions.
3. Heider (1958), desire is a motivational state that arises from within the person and that represents the person's own wish or want. Desire is therefore a subjective, psychological condition that is not necessarily reflected in an individual's actual or potential actions.
The aforementioned theorists and researchers emphasize the intra-individual nature of sexual desire. That is, some innate biological need arising from within the body (and considered by some to be subject to learning and socialization socialization /so·cial·iza·tion/ (so?shal-i-za´shun) the process by which society integrates the individual and the individual learns to behave in socially acceptable ways.
n. processes) produces a subjective state of sexual desire that impels the individual to seek out or become receptive to sexual objects and experiences.
Other investigators, however, view desire as an externally generated phenomenon. Desire is located in the partner rather than in oneself since it is a feeling of being drawn to the other (Verhulst & Heiman, 1979). Sexual desire originates from an external source of stimulation located within the desired object rather than from some need arising within the desiring individual.
Levine (1987), however, argues that sexual desire is generated and influenced by both internal and external events. According to his model, sexual desire is a personal, subjective experience that is defined as "the psychobiologic energy that precedes and accompanies arousal and tends to produce sexual behavior" (p. 36). Levine believes that desire is best viewed as the product of an interaction among (a) the neuroendocrine neuroendocrine /neu·ro·en·do·crine/ (-en´do-krin) pertaining to neural and endocrine influence, and particularly to the interaction between the nervous and endocrine systems.

In this paper, we have operationalized sexual desire in the terms of cognitive events (sexual thoughts, sexual fantasies sexual fantasy Psychology Private mental imagery associated with explicitly erotic feelings, accompanied by physiologic response to sexual arousal. See Sexual desire. ). Our concept of sexual desire is not associated with any overt sexual activity. We believe that thoughts and fantasies represent motivational aspects of sexual experience and therefore may serve as indirect measures of sexual desire (Sherwin, 1988).
Age. Kinsey, Pomeroy, and Martin (1949) stated that of the eleven factors that are significant in understanding human sexuality, none seemed more important than age. Sexual behavior in women and men declines steadily from adolescence into older age, and to a lesser extent there is diminution Taking away; reduction; lessening; incompleteness.
The term diminution is used in law to signify that a record submitted by an inferior court to a superior court for review is not complete or not fully certified. in sexual desire (Maurice, 1999). Some researchers report that older adults continue to be interested in sex as long as poor health does not affect their sexual desire. In particular, aging does not appear to have any effect on female sexual desire (Masters, Johnson, & Kolodny, 1994).
However, Levine (1998) concludes that sexual desire for both women and men changes considerably in older ages. McKinlay and Feldman (1994) reported that in their study of men ages 40 to 70, sexual desire and frequency of sexual thoughts and dreams decreased with age. In Schiavi's study (1999) of healthy men ages 45 to 74 years who were living in stable sexual relationships, sexual desire decreased as age increased. Others have also found that sexual interest declines in aging women (Hallstrom & Samuelsson, 1990; Osborn, Hawton, & Gath, 1988). One cause of these conflicting results may be variation in the measure of sexual desire employed. Another may be the failure to take into account the influence of other relevant factors.
Hormones. A second biological factor is sex hormones sex hormone

It has a membership of over 49,000 and represents 90 percent of U.S. , 2000). As one ages, there are many changes in the production and functioning of sex hormones (Morley, 2003). Women experience an almost complete cessation of the production of estradiol estradiol /es·tra·di·ol/ (es?trah-di´ol) (es-tra´de-ol) the most potent estrogen in humans; pharmacologically, it is often used in the form of its esters (e.g., e. cypionate, e.

A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of , which, in turn, might cause discomfort or pain during intercourse (Maurice, 1999). Thus, cessation of sexual activity in older women may reflect the fact that intercourse is painful rather than a decline in sexual desire. In men, testosterone testosterone (tĕstŏs`tərōn), principal androgen, or male sex hormone. One of the group of compounds known as anabolic steroids, testosterone is secreted by the testes (see testis) but is also synthesized in small quantities in the levels decline gradually from age 40 to age 70; the total decline in free testosterone is typically 30 percent (Schiavi, 1999).
Studies suggest that testosterone is associated with increased levels of sexual desire and enjoyment of sex in some post-menopausal women (Sarrel, 1999; Sarrel, Dobay, & Wiita, 1998; Sherwin, Gelfand, & Brender, 1985). According to several researchers, sexual desire in women is, in biological terms, more dependent on androgen androgen (ăn`drəjən): see testosterone.

Illness. Chronic disorders, such as cardiovascular disease Cardiovascular disease

cardiovascular disease , diabetes, arthritis, and cancer, may have negative effects on sexual functioning and response (Maurice, 1999; Schiavi, 1999). These diseases impair sexual function both directly, by acting on physiological mechanisms (by interfering with the endocrine, neural, and vascular processes that mediate sexual response) and reproductive structures, and indirectly, by limiting total body function.
Cardiovascular diseases, such as myocardial infarction myocardial infarction: see under infarction. , hypertension, and peripheral vascular insufficiency INSUFFICIENCY. What is not competent; not enough. (atherosclerosis atherosclerosis (ăth'ərōsklərō`sĭs): see arteriosclerosis.

Many studies have reported a loss of sexual drive in as few as 10% to as many as 70% of patients after myocardial infarction (Papadopoulos, 1989). Studies on sexual behavior after a stroke report decreased levels in sexual desire (Angeleri, Angeleri, Foschi, Giaquinto, & Nolfe, 1993; Boldrini, Basaglia, & Calanca, 1991). There are, however, methodological issues to be considered in evaluating the results of these studies, including the lack of consideration of (a) age effects and (b) the level of sexual function and desire prior to infarction.

Although there are numerous studies on the sexual consequences of anti-hypertension treatment, there are few on sexual functioning in persons with these illnesses who are not receiving treatment (Schiavi).

Schiavi, Stimmel, Mandeli, and Rayfield (1993) found that diabetic men, screened for nondiabetic pathology, show decreased levels of sexual desire compared to age-matched healthy controls. The duration of the disease (insulin-dependent or noninsulin-dependent diabetes) and type of treatment do not appear to be significantly related to the occurrence of sexual problems (Schiavi). On the other hand, Masters et al. (1994) contend that men with diabetes do not have decreased levels of sexual desire.
Sexual functioning and response in diabetic women have been studied less extensively. However, it has been found that diabetic neuropathy Diabetic Neuropathy Definition
Diabetic neuropathy is a nerve disorder caused by diabetes mellitus. Diabetic neuropathy may be diffuse, affecting several parts of the body, or focal, affecting a specific nerve and part of the body. , a condition that affects the nerve supply to the pelvis, can cause impaired sexual desire in women (Masters et al., 1994). Unfortunately, there are few controlled studies of the psychology of sexual dysfunction sexual dysfunction

Arthritis in aging adults is a major cause of discomfort and disability. It has often been assumed that those with arthritis have sexual difficulties, but this has seldom been systematically investigated (Schiavi, 1999). One study of males (mean age 58) reported that there were decreased levels of sexual desire in the arthritic patients in comparison to the control group of non-arthritic men (Blake, Maisiak, Kaplan, Alarcon, & Brown, 1988).
Prostate disease occurs frequently in aging men. It is the second most prevalent cancer, present in almost 90% of men ages 80 and older, and the second most common cause of death from cancer (Masters et al., 1994; Schiavi, 1999). Sexual dysfunction is a common complication of this disease and its treatment (Jakobsson, Loven, & Hallberg, 2001). Fortunately, nerve-sparing prostatectomy nerve-sparing prostatectomy Urology Any prostatectomy intended to preserve sexual function has been proven to have positive effects on the sexual functioning of patients (Gralnek, Wesells, Cui, & Dalkin, 2000). Even though nerve-sparing operations can often provide preservation or recovery of sexual functioning, recovery also depends on the age of the patient (Catalona & Basler, 1993; Miyao et al., 2001). Moreover, conclusions are limited by insufficient information about sexual response and functioning prior to surgery, other diseases, and medications (Schiavi).
Medications. Numerous prescription drugs prescription drug Prescription medication Pharmacology An FDA-approved drug which must, by federal law or regulation, be dispensed only pursuant to a prescription–eg, finished dose form and active ingredients subject to the provisos of the Federal Food, Drug, have adverse effects on sexual functioning, including antidepressant antidepressant, any of a wide range of drugs used to treat psychic depression. They are given to elevate mood, counter suicidal thoughts, and increase the effectiveness of psychotherapy. and anti-hypertension medications. Moreover, adverse drug effects have been reported much more frequently in the aging population than in the general population (Wade & Bowling, 1986). Gender differences should also be examined. The use of prescribed medications and the rate of adverse effects of drug therapy are consistently higher in female than male elderly populations (Schiavi, 1999).

v.intr. with sexual desire (Butler, Lewis, Hoffman, & Whitehead, 1994). Negative attitudes toward sex among older women and men are common (Story, 1989). In part, these attitudes reflect America's youth-oriented culture. American popular culture equates sex appeal with the characteristics of a youthful body, such as a firm body and smooth skin (Levy, 1994). Another contributor is the emphasis on reproduction. In populations where the primary purpose of sexual intimacy is seen as reproduction, it is considered inappropriate for a post-menopausal woman to continue to be sexually active (Deacon, Minichiello, & Plummer, 1995; Levy; Story). We are especially interested in the relative impact of such attitudes on sexual desire.
Sexuality is socially and culturally constructed (Irvine, 1990; Masters et al., 1994; Stock, 1984; Tiefer, 1991, 2004). Culture provides a set of expectations, beliefs, and attitudes about sexuality, and women and men draw on these to attach meaning to their experiences. In the U.S., aging women and men's sexuality is influenced by a cultural environment that is fraught with both ageism ageism Geriatrics A bias or belief that may be held by a health care provider that depression, forgetfulness, and other disorders are a normal part of aging and that older individuals will not benefit from treatment of mental disorders.

soci·o·cul factors work to minimize or deny the existence or value of sexuality for older persons (Gott & Hinchliff, 2003). Cole (1988) describes her sample of menopausal-aged women as having a sense of "despair about their lives [because they were] holding an image--perhaps a male image, or a youthful image--of how sex is supposed to be."
The images available in U.S. society about sexuality and the aged are negative. Sex is seen as unseemly, even unnatural in the old. One elderly gentleman contended, "We're supposed to be asexual asexual /asex·u·al/ (a-sek´shoo-al) having no sex; not sexual; not pertaining to sex.
1. Having no evident sex or sex organs; sexless.
2. , and those who refuse to be so are branded dirty old men" (Stock, 1999, p. 51). The media bombards us with a plethora of sexual images, mainly those of young, energetic people. The sexuality of older women and men is rarely portrayed in a positive light (Brown, 1989; Levy, 1994). These images influence many older people's beliefs, leading to the conclusion that sex is only for the young and beautiful (Hillman Hillman was a famous British automobile marque, manufactured by the Rootes Group. It was based in Ryton-on-Dunsmore, near Coventry, England, from 1907 to 1976. Before 1907 the company had built bicycles. & Stricker, 1994). These stereotypes and myths set in motion a self-fulfilling prophecy self-fulfilling prophecy, a concept developed by Robert K. Merton to explain how a belief or expectation, whether correct or not, affects the outcome of a situation or the way a person (or group) will behave. . Older people may withdraw from any form of sexual expression and ignore or suppress sexual desire because it is "sick," "unsuitable," or "wrong." According to Sloane (1993), many older women and men do feel asexual.
Health care providers may contribute to the silence surrounding sexuality in aging by not talking with their aging and elderly patients about sexuality issues (Fallowfield, 2002; Stead, Fallowfeld, Brown, & Selby, 2001). Some doctors do talk to their older patients about sexuality. In fact, some prescribe sexual education classes as a form of sex therapy. In a study by White and Catania (1982), the experimental groups (ages 60 to 83 years) showed significant increases in sexually permissive permissive adj. 1) referring to any act which is allowed by court order, legal procedure, or agreement. 2) tolerant or allowing of others' behavior, suggesting contrary to others' standards.

Aging women and men with inadequate knowledge of sex and sexuality may be vulnerable to faulty expectations and concerns about performance (White & Catania, 1982). There is a widespread assumption that vaginal intercourse is the only "real sex" (Blank, 2000); therefore, if the person, by reason of dysfunction or disease, is unable to have intercourse Verb 1. have intercourse - have sexual intercourse with; "This student sleeps with everyone in her dorm"; "Adam knew Eve"; "Were you ever intimate with this man?" , he or she may lose interest in sex. To meet the challenge of maintaining sexual activity during the aging process, couples have to make love with what they have. Hands and mouths are reliable; penises and vaginas are not. However, it is common for couples to end their sexual lives together because one or both partners believe that an erection is necessary to "get the job done" or see non-coital sex non-coital sex Sexology Any form of safe sexual activity that does not include vaginal penetration–eg, masturbation, frottage. See Safe sex practices. as immoral or perverse (Blank; Cogen & Steinman, 1990; Levine, 1998).
The presence or absence of a sexual partner is an extremely important factor in understanding differing levels of sexual desire and activity among aging women and men. Many people consider sexual intimacy to be only or most appropriate in marriage (Levy, 1994). Many older persons are not married or no longer live with a spouse. There are 26.6 million men and 33 million women over 55; only 74% of the men and 50% of the women are married and living with a spouse (Smith, 2003). This gap in the living situation of men and women increases with age.
Marriage is the most common social arrangement within which normative sexual activity takes place (Rossi, 1994; Schiavi, 1999). Thus, the death of a spouse usually leads to the cessation of sexual behavior (Rossi). Women tend to marry older men, which is a main reason that women are more likely to be widowed.

As a result, 40% of older women live alone, compared with 16% of older men (AARP AARP, a nonprofit, nonpartisan national organization dedicated to "enriching the experience of aging"; membership is open to people age 50 or older. Founded in 1958 by Ethel Percy Andrus as American Association of Retired Persons, AARP now has over 30 million , 1997).

For those who do have a sexual partner, monotony in sexual relationships, such as predictability of sexual activities and over-familiarity with the partner, may also contribute to a loss in sexual desire (Levy, 1994).

Norms that limit sexual activities to marriage, combined with the habituation effect, may cause early diminution of sexual desire (Call, Sprecher, & Schwartz, 1995). One study on the relationship between women's menopausal status and sexual desire found that women who were of menopausal status had lower sexual desire compared to when they were in their 40s (No women were on hormone replacement therapy Hormone Replacement Therapy Definition

(Avis, Stellato, Crawford, Johannes, & Longcope, 2000). Past research also found that married women who reported lower levels of desire were more likely to agree that interest in sex declines with age, and were more likely to say that they were less aroused now than when they were in their 40s (Avis et al., 2000).
On the other hand, the results of the Duke studies (Pfeiffer, Verwoerdt, & Davis, 1972; Verwoerdt, Pfeiffer, & Wang, 1969) found that marital status marital status,
n the legal standing of a person in regard to his or her marriage state. had little effect on sexual interest. In data from the Consumers Union survey on sex and aging involving 4,246 men and women over the age of 50, the majority of happily married women and men rated sex as important in marriage, while 54 percent of unhappily married wives rated sex as being "of little importance" (Brecher & Editors, 1984). These results suggest that satisfaction with the relationship may be an important influence on desire; results such as those reported by Avis may reflect marital unhappiness rather than loss of desire.
Sex is important for many unmarried older adults, too (Masters et al., 1994). Some fulfill their desire for sexual intimacy within a long-term committed relationship A committed relationship is an interpersonal relationship based upon a mutually agreed upon commitment to one another involving exclusivity, honesty, or some other agreed upon behavior. . We have little information about the sexual activity of older persons who live alone.
Household income is potentially an important social factor. Other things equal, an individual or couple with a higher income has access to health care and activities that may maintain general physical and mental health. Better health, in turn, is likely to be associated with sexual desire. The problem of decreased to almost nonexistent non·ex·is·tence

non sexual desire is significantly more common in women of lower social class (Garde & Lunde, 1980; Hawton, Gath, & Day, 1994; Osborn et al., 1988). This may be due to a lack of sex education, to either age or social class, or to negative attitudes held by the women and their partners.

NFO National Family Opinion Research. A commercial data collection agency, NFO maintains a consumer panel of 565,000 individuals who are broadly representative of the population of the United States and who have agreed to participate in surveys. From this consumer panel, NFO drew a representative sample of 3,450 persons ages 45 and older. This sample was balanced to nationally representative quotas using the Current Population Survey.
Of the sample, 2,206 eligible persons were contacted by telephone and informed about the survey. Potential respondents were told that "the purpose of the study is to better understand the role of sexuality in the lives of mid-life and older persons." They were also given the usual assurances of confidentiality. On March 8, 1999, surveys were mailed to the 1,709 men and women who agreed to participate (77% of those contacted). Each questionnaire was sent with a $1 cash incentive to encourage completion and return of the questionnaire. By March 22, 1999, 1,384 participants had returned completed surveys (81% of those who were sent the survey, 62% of those contacted). The final data were weighted to reflect Census estimates for age and gender of the over-45 population. The margin of potential sampling error for the final sample (745 women and 639 men) is +/- 2.6%.
The following research questions were addressed in this study:
1. What influences are related to low sexual desire in older women and men?
2. What biopsychosocial factors are the primary influences related to decreasing sexual desire?
Level of sexual desire. Level of sexual desire was measured by two questions: "How frequently do you feel sexual desire? This feeling includes wanting to have sexual experiences, planning to have sex, and feeling frustrated due to lack of sex," and "How frequently do you have sexual thoughts, fantasies, or erotic dreams?" Each question was answered using an 8-point scale from 1 (more than once a day) to 8 (not at all). We created an index of desire by computing the average of the numeric responses to these two items. If the participant answered neither item, no score was computed. The reliability (alpha) of this scale was .86 for men and .87 for women.
Illnesses. Illnesses were measured by a list of 8 illnesses prefaced by the request to "Indicate which of the[se] conditions you have been diagnosed with." Four of the illnesses listed were chosen by 10% or more of the sample. Diabetes, high blood pressure, and arthritis met the 10% criterion for both women and men. The fourth illness included for women was depression, and the fourth illness included for men was an enlarged prostate Enlarged Prostate Definition
A non-cancerous condition that affects many men past 50 years of age, enlarged prostate makes urinating more difficult by narrowing the urethra, a tube running from the bladder through the prostate gland. . We constructed a summary measure of the number of these four illnesses reported by each respondent. Also, each person who reported being diagnosed with an illness was asked whether she or he was currently receiving treatment for that illness; answers were recorded as (Y/N Y/N Yes/No ).
Medications. Medications were selected from a list comprised of 11 items. The questionnaire asked the respondent, "In the past two weeks, have you taken any of the following prescription drugs?" Respondent reports (Y/N) of taking the medication were correlated with desire; four medications were correlated significantly (p < .01) with desire for women, and 2 medications were correlated significantly for men.
Attitudes toward sex. Attitudes toward sex were measured with a series of nine Likert scale Likert scale A subjective scoring system that allows a person being surveyed to quantify likes and preferences on a 5-point scale, with 1 being the least important, relevant, interesting, most ho-hum, or other, and 5 being most excellent, yeehah important, etc attitude items. The items are listed on Table 1. Potential responses for each item ranged from 1 (strongly agree) to 5 (strongly disagree). We conducted factor analyses of the responses to these nine items separately for women and for men. The results are shown in Table 1. In each analysis, three factors attained eigenvalues eigenvalues
statistical term meaning latent root. greater than one, but the third had no items that attained loadings of .50 or greater. Looking at the remaining factors, for both men and women, factor 1 includes items f, g, and h, which assess the respondent's attitudes about sex for the self; the reliability (alpha) of the scale for women is .833, and for men, .829. Item e attained a loading of .51 in the analysis for women, but only .30 in the analysis for men; it was not included. We used the three items to create a mean score for each participant, provided that the participant had answered at least two of the three items. Factor 2 includes items a, b, and c, which assess attitudes toward sex in relationships; the reliability (alpha) of the scale is .748 for women and .79 for men. We used the three items to create a mean score for each participant, provided that the participant had answered at least two of the three items. The two factors explained 44% of the variance in the analysis for men and 48% in the analysis for women.
Household income. Household income was reported by each respondent. The resulting distributions for men and women were divided into quartiles. The distributions of reported income differed for women and men. For women the household income categories are as follows: 1 = $7,500-$19,999; 2 = $20,000-$37,499; 3 = $37,500-$74,999; 4 = $75,000-$175,000+. For men the household income categories are as follows: 1 = $7,500-$14,999; 2 = $15,000-$29,999; 3 = $30,000-$59,999; 4 = $60,000-$175,000+.
Table 2 displays basic demographic characteristics of the sample. Men are more likely to be employed than women. The sample is primarily European-American. About 56% of the men and 64% of the women are married and living with a partner. In order to assess the representativeness of the sample, we compared the age and relationship status distribution for the (weighted) sample with that of the United States population ages 45 and older (United States Bureau of the Census, 2002). Two differences were noted. Men ages 45 to 54 in the sample were less likely to be married and more likely to be widowed, as were women over 75. Differences in the other cells were generally less than 4%.
Responses to the two items used to measure sexual desire were combined to form an index as described earlier. The average desire score for men was 2.82 (SD = 1.53, n = 627), and the average for women was 3.0 (SD = 1.46, n = 709), with a score of 1 indicating high desire. Note that men on average report slightly higher levels of desire than women.
The results show that there is a strong positive relationship between increasing age and low levels of sexual desire for both women and men. To allow for cross-gender comparison, we divided the distributions of desire scores for men and for women into groups. For women, the "low desire group" represents 22.9% of women; all have a desire score of 8. The "high desire group" for women represents 22.2% of women; their desire scores range from 1 to 3.5, inclusive. For men, the "low desire group" represents 21% of men; their desire scores range from 6.0 to 8.0, inclusive. The "high desire group" represents 26.9% of men; their desire scores range from 1.0 to 1.5, inclusive. The relationships between age and desire for men and for women are displayed in Table 3. The percentage of men and women attaining low scores on desire increases from less than 5 percent at ages 45 to 49, to 59 percent or more at ages 80 to 84. The correlation between sexual desire (index score) and age (continuous) is .51 for women (p < .000, n = 704), and .52 for men (p < .000, n = 625).
High blood pressure is significantly related to low levels of sexual desire for both women and men. Nearly the majority of women and men who have been diagnosed with high blood pressure have desire scores in the lowest groups. As noted earlier, each person reporting an illness was asked whether he or she was currently being treated. We can measure the effect of treatment by comparing the percentage of those diagnosed with high blood pressure who attain low scores on desire with those who were diagnosed and treated who attain low scores. There was a slight decrease in the percentage of women and men with a very low level of desire who have been diagnosed and treated. The correlation between hypertension and desire was small but significant: .12 among men (p < .01) and .15 among women (p < .01).
Among men, we found that diagnosis of an enlarged prostate was related to low levels of desire (r = .14, p < .01). Again, the correlation is small but significant. Comparison of desire score distributions before and after treatment showed little change.
Diagnoses of diabetes, arthritis, and depression were not significantly related to levels of sexual desire for women. A diagnosis of diabetes was not significantly related to levels of sexual desire for men.
Regular use of four medications is significantly related to low levels of sexual desire in women. These prescription medications include anticoagulants Anticoagulants
Drugs that suppress, delay, or prevent blood clots. Anticoagulants are used to treat embolisms.
Mentioned in: Embolism, Heart Valve Replacement , cardiovascular medications, medications to control elevated cholesterol, and medications for hypertension. The correlations are small, ranging from .13 to .19. Among men, only reports of taking anticoagulants and medications for hypertension are significantly related to low levels of sexual desire; the correlations are .17 and. 14, respectively.
Attitudes Toward Sex
The correlations of the two attitude indices with sexual desire are shown in Tables 4 and 5, for women and men. For women, scores on the index of attitudes about sex in relationships (items a, b, and c) are significantly correlated with desire; women who strongly agree that sexual activity is important to their quality of life and their relationships attain high desire index scores (r = .19, p < .000.), reflecting low desire. With regard to the second index, women who strongly agree that they do not enjoy sex and that they would be happy never having sex again have lower desire index scores (r = -.57, p < .000.), reflecting high desire. The results are similar for men, with correlations of .31 and -.47, respectively. These correlations are substantial and significant for both men and women.
We can gain insight into the interrelations of attitudes and desire by looking at the endorsement of the attitude items by men and women with the highest and lowest scores on desire. Sixty percent of women who have desire scores in the lowest group (23% of the sample) disagree or strongly disagree that "sexual activity is important to my overall quality of life," whereas less than 2% of these women agree or strongly agree with this statement. Seventy percent of women who score in the highest group on desire (23% of the sample) agree or strongly agree that "sexual activity is important to my overall quality of life," whereas a little more than 7% of these women disagree or strongly disagree with Verb 1. disagree with - not be very easily digestible; "Spicy food disagrees with some people"
hurt - give trouble or pain to; "This exercise will hurt your back" this statement.
This trend is similar for men. Most men who score in the lowest group of desire (21% of the sample) disagree that "sexual activity is important to my overall quality of life," and most men who score in the highest group of desire (27% of the sample) are more likely to agree with this statement.
Nearly 98% of women with scores in the highest group of desire disagree or strongly disagree that "sex is only for younger people." Surprisingly, 42% of women who score in the lowest group of desire disagree or strongly disagree that "sex is only for younger people." Nearly 97% of men who score in the highest group of desire disagree or strongly disagree that "sex is only for younger people." More than 75% of the men who score in the lowest group of sexual desire also disagree or strongly disagree that "sex is only for younger people."
Partner Presence / Marital Status
The survey included a categorical measure of marital status and a question asking whether the respondent had a sexual partner. All of the married persons answered "yes" to the latter, as did an additional 1.7 percent of women and 3.5 percent of men. We used the sexual partner measure, recognizing that in most cases the partner is a spouse. The data presented in Table 6 show that there is a marked difference in the percentage of aging men and women who have a sexual partner.
For women, having a sexual partner is highly related to the level of sexual desire. (See Table 4.) The correlation is -.41 (p < .01), indicating that women who have a partner attain lower desire scores, reflecting higher levels of desire. For men, the correlation is much smaller, -.19 (p < .01). Thus, the relationship between desire and having a partner is much stronger for women.
The impact of a partner on one's sexual desire depends in part on the characteristics of the partner. Each participant who reported having a partner was asked whether the partner had any physical or emotional limitations "which restrict your sexual activity." We constructed an index of both presence and limitations (Y/N) of partner; a score of 1 indicates a partner with no limitations, a score of 2 indicates presence of a partner with limitations, and 3 indicates no partner. The average desire scores for women are 5.19, 5.72, and 7.06, respectively (univariate ANOVA anova
see analysis of variance.
ANOVA Analysis of variance, see there , F = 91.67, p < .000, df = 2). Pairwise comparisons indicate that each is significantly different from the other two (p < .004). The average scores for men are 3.78, 3.84, and 4.85, respectively (ANOVA, F = 14.02, p < .000, df = 2). Pairwise comparisons indicate that the score for men with no partner is significantly different from the means of the other two groups (p < .001). The relationship is much stronger for women (partial [Eta.sup.2] = .189) than for men (partial [Eta.sup.2] = .045).
The data show that household income is negatively correlated with sexual desire scores both in women (r = -.35, p < .000) and in men (r = -.28, p < .000). Thus, older persons with greater income experience higher levels of desire.
In summary, the bivariate bi·var·i·ate
Mathematics Having two variables: bivariate binomial distribution.
Adj. 1. results indicate that among women, age, high blood pressure, prescription medications, negative attitudes toward sexuality, absence of a sexual partner, and low household income are correlated with low sexual desire. The substantial correlates (> .40) are age, attitudes, and presence of a partner. Thus, medical/biological, psychological and relational factors are related to desire. We conducted regression analyses with sexual desire as the outcome variable and all of the variables listed above as predictors. We used two-stage models, entering the biomedical bi·o·med·i·cal

2. Of, relating to, or involving biological, medical, and physical sciences. and relational factors in step 1 and entering attitudes in step 2. We noted in the Introduction our view that biological factors are necessary but not sufficient explanations of desire. The biopsychosocial model The biopsychosocial model is a general model or approach that posits that biological, psychological (which entails thoughts, emotions, and behaviors) ,and social factors (abbreviated "BPS") all play a significant role in human functioning in the context of disease or illness. suggests that psychological and social factors will explain variance beyond that explained by biology. We are especially interested in attitudes, which are largely socially constructed and reflect the influence of culture. The results for women are displayed in Table 7.
Among women, the following predictors were significantly (p <.000) associated with desire in step 1: presence of a sexual partner, education, age, number of medications taken regularly, and number of diagnosed illnesses. The adjusted [R.sup.2] for Model 1 is .348. When the two attitude indices are added, the variables that were significant in step 1 remain significant, with the exception of education, and the attitude indices are also highly significant (p < .000). The results suggest that attitudes mediate the effect of education. The adjusted [R.sup.2] for Model 2 is .585, indicating that inclusion of attitudes substantially increases the variance explained. The change in [R.sup.2] is highly significant (F = 189.74, p < .00). The largest coefficients are associated with attitudes toward sex for self, age, attitudes toward sex in relationships, and having a sexual partner. Thus, attitudes are substantially related to sexual desire in women, and there is an effect of age that is not explained by illnesses or medications taken regularly. Having a partner is also associated with having greater desire.
Among men, the bivariate results indicate that age, high blood pressure, enlarged prostate, anticoagulants and medications for hypertension, presence of a sexual partner, negative attitudes toward sexual activity, and income were all negatively correlated with reported sexual desire. The substantial correlates (> .40) are age and attitudes. In step 1 of the regression analysis In statistics, a mathematical method of modeling the relationships among three or more variables. It is used to predict the value of one variable given the values of the others. For example, a model might estimate sales based on age and gender. , only two variables were significantly (p < .000) associated with desire: education and age. Older men and men with less education reported lower desire. Presence of a sexual partner, number of medications, and number of diagnosed illnesses were not associated with desire. The adjusted [R.sup.2] is .313. In Model 2, both attitude indices are associated with desire (p <.000), and the adjusted [R.sup.2] increases to .478. The change in [R.sup.2] is significant (F = 94.79, p <.00); results are displayed in Table 8. Thus, attitudes are also substantially related to sexual desire in men, and there is an effect of age that is not explained by illnesses or medications taken regularly. However, having a partner is not associated with having greater desire among men.
This study explored biopsychosocial factors, including age, illness, medication use, attitudes, marital status, presence or absence of a sexual partner, and household income, in relation to sexual desire in a representative sample of women (n = 745) and men (n = 639) over the age of 45.
The results indicate that age is significantly associated with desire, net of the effect of other variables studied. The relationship is stronger among men ([beta] = .35) than among women ([beta] = .26). These results are consistent with previous findings (Hallstrom & Samuelsson, 1990; Kontula, 2002; Levine, 1998; Maurice, 1999; McKinlay & Feldman, 1994; Osborn et al., 1988; Schiavi, 1999). Sexual desire decreases as women and men age. However, sexual desire does not decrease as fast as popular belief dictates. In our study, it is not until age 75 or older that the majority of women and almost a majority of men report a low level of sexual desire.
Illnesses and Medications
Although being diagnosed with some illnesses and reports of taking medications to lower cholesterol were negatively correlated with desire, these predictors were not significant in the regression analyses for men. These predictors were significant in the analyses for women, although the standardized coefficients are not large. Women who report taking a greater variety of medications in the two weeks prior to the survey have lower desire scores ([beta] = .11). Women who report having been diagnosed with more illnesses also have lower desire scores ([beta] = .12). Note that relatively few participants report taking those medications thought to affect desire. Although these drugs, such as drugs for high blood pressure, may substantially affect those who take them, their use is not widespread. Thus, biological factors have a modest effect on female sexual desire.
Attitudes Toward Sex
Negative attitudes toward sex are correlated with low sexual desire. In the regression analyses, rating sex as important to one's self was associated positively and substantially with desire (for men, [beta] = -.27, for women [beta] = -.44), controlling for age. Rating sex as important to one's relationships was also a significant predictor of desire (for men, [beta] = .25; for women [beta] = .19) The effects of attitudes are larger than the effects of any other predictor included in our analyses except age.
Education was significantly related to desire for both men and women in Step 1 of the regression. When attitudes are added in Step 2, it is no longer significantly related for women and the [beta] in the male analysis is smaller. We believe that attitudes mediate much of the relationship between education and desire. Greater education may undermine the negative stereotypes of sexual expression by older persons.
Presence of Partner
Even though sexual desire remains intact in healthy older persons, they need a partner, especially an interested partner, in order to continue partnered sexual activities, and for some, to continue having sexual desire. The absence of a partner or an interested partner can be an obstacle for many. In our study, having a partner is a significant predictor of desire among women but not among men. More than 78% of the women who have a low level of sexual desire are without a sexual partner, and more than 83% of the women with a high level of sexual desire have a partner. Also, 84% of the men with a high level of desire have a partner. What is surprising is that the majority of men with a low level of desire have a partner. Also, whether the partner has limitations that affect the respondent's sexual activity is related to reports of desire by women but not by men. These results suggest that a woman's desire is attuned at·tune
tr.v. at·tuned, at·tun·ing, at·tunes
1. To bring into a harmonious or responsive relationship: an industry that is not attuned to market demands.
2. to her relationship context, but a man's desire is not.
These results provide some order to the scattered findings of past research. Across this sample of persons 45 and older, the principal influences on sexual desire are age and the importance of sex to the person. For women, having a partner, taking medications and being diagnosed with illnesses also play a modest role. These results suggest that stereotypes of older persons as not interested in sexual intimacy are wrong. They also suggest that negative attitudes about sexual activity among older persons need to be challenged so that future cohorts are not influenced by such attitudes. It is particularly important that health care professionals not convey negative attitudes to older patients. Finally, we should scrutinize scru·ti·nize

scru economic and residential arrangements for the elderly and structure them to facilitate rather than hinder intimate relationships.
More generally, given the set of questions asked, the results provide little support for an exclusively medical model of sexuality among the aging. In our results, the most significant influences are psychological (attitudes) and relational (the presence of a partner). These results are based on a large sample of men and women ages 45 and older. Although the completion rate of 62% of those contacted may be a limitation, the age and marital status of those who returned questionnaires closely parallel the national population.
Our literature review identified several influences on the sexual desire and functioning of older persons. The one set of influences discussed for which we do not have measures is hormones. Ideally, future research should not only collect comprehensive survey data of the type reported here, but also measure levels of estrogen and testosterone on at least a subsample sub·sam·ple

An important limitation is the racial homogeneity Homogeneity
The degree to which items are similar. of the sample. Our data do not include enough non-Caucasian participants to investigate links between race and sexual desire.

Culpability generally implies that an act performed is wrong but does not involve any evil intent by the wrongdoer. role in low sexual desire. Within different races exist different cultures. Cultures provide different ideologies, definitions, and attitudes for framing sexual functioning and experiences. This is also an area of research that needs to be expanded.
A potentially important limitation is the fact that measures of diagnosed illness and of medications taken are self-report. Bias due to failure to remember may be a factor, particularly among the elderly. In this study, such bias should be less influential on reports of medication taken, since the questions asked about medications taken in the two weeks prior to the survey. Research linking respondents' self-reports to their pharmaceutical records in relation to measures of sexual functioning would be a desirable, albeit difficult, next step.

Several of our findings suggest that there are important differences in sexual desire between women and men.
