Dietary Iron Intake in Relation to Age at Menarche: A Prospective Cohort Study in Chilean Girls.

ABSTRACT:

Background

Early onset of menarche is considered an important risk factor for a number of diseases in adulthood. Iron intake may be related to pubertal timing because of its role in childhood growth and reproductive function.

Objective

We investigated the relation between dietary iron intake and age at menarche in a prospective cohort of Chilean girls.

Methods

Overall, 602 Chilean girls were included in the Growth and Obesity Cohort Study, a longitudinal study that began in 2006 when the girls were 3-4 y old. Starting in 2013, diet was assessed every 6 mo through 24-h recall. The date of menarche was reported every 6 mo. Our analysis included 435 girls with prospective data on diet and age at menarche. We used a multivariable Cox proportional hazards regression model
