Does vitamin D affect timing of menarche?

In a recently published prospective study, Villamor et al. found increased risk of early menarche in vitamin D‐deficient girls compared to vitamin D‐sufficient girls in Bogota, Columbia. The association was not fully explained by differences in body mass index‐for‐age z‐scores. The mechanism for the association, if real, has not been elucidated, but could potentially involve vitamin D receptor polymorphisms. Early menarche and vitamin D deficiency are both associated with poor health outcomes, and further exploration of their association is important for women's health.
