Preventing vitamin D deficiency may help delay early puberty.

A presentation at The Endocrine Society's 95th Annual Meeting held in San Francisco this year revealed a greater risk of precocious puberty in girls with deficient levels of vitamin D in comparison with girls who entered puberty at a normal age. *

The research included 110 girls aged 7 to 10 years, among whom 35 were categorized as having experienced precocious puberty according to the Tanner Scale. Blood samples collected from the subjects were analyzed for serum 25-hydroxyvitamin D levels and other factors.

Vitamin D levels were lower on average among girls with early puberty in comparison with girls who entered puberty at a normal age. Forty-four percent of the girls who underwent precocious puberty had serum 25-hydroxyvitamin D levels that were classified as severely deficient at less than 10 ng/mL in comparison with 21% of the normal group.

Editor's Note: In additional experimentation, the researchers found that the administration of vitamin D suppressed the ability of N-methyl-D-aspartate (NMDA) to release gonadotropin-releasing hormone (GnRH, which triggers the ovulation process) from neurons.
