Weight Status in Young Girls and the Onset of Puberty

Abstract: Higher BMI z score in girls as young as 36 months of age and higher rate of change of BMI between 36 months old and grade 1, a period well before the onset of puberty, are associated with earlier puberty, which suggests that increasing rates of obesity in the United States may result in an earlier average age of onset of puberty for US girls.

“…While a positive association between household income and age at menarche is consistent with at least two other studies [8,10], the lack of statistically significant influences of parental education on this outcome in the present study contrasts some previous reports [9,13]. This may perhaps be due to the fact that parental education has been measured inconsistently (maternal educational attainment only versus maximum educational attainment of both parents/guardians).…”

“…Among girls in the United States, recent epidemiologic evidence suggests that low socioeconomic status (SES) may be related to early puberty [8][9][10], as determined by entry into the stage 2 of breast development based on the staging system developed by Tanner and Whitehouse [11]. A comprehensive review published in 2003, however, reported inconsistent associations between socioeconomic circumstances and the onset of puberty: developed versus developing countries showed particularly marked variations [12].…”

“…A higher BMI during adolescence may be associated with younger age at MS onset in women 13. Attainment of sufficient body weight, and particularly body fat, is believed to be necessary for menarche to occur in girls,3, 14, 15, 16 and higher body weight is associated with earlier pubertal onset in girls.…”

“…Early onset of thelarche has been reported in girls with high BMI at the age of three years, and in those with a rapid elevation of BMI from three years of age to the age of entry into the first grade [4]. The rapid catch-up growth in children born small-for-gestational age [5] with associated decreased insulin sensitivity, and increased IGF-1 levels, also results in early onset of pubarche for the same reason.…”
