... 2012 and 2017, sons and daughters provided information on a wide range of pubertal milestones—including Tanner stages, axillary hair growth, and age at menarche or voice break and first ejaculation—every 6 months from 11 years of age until full sexual maturation. Data were analyzed using a regression...

Annually, we measured BMC by dual‐energy X‐ray absorptiometry (DXA), physical activity and calcium intake by questionnaire, and pubertal development (Tanner stage) by examination for up to 7 years. Mixed‐effects regression models were used to assess...
