Abstract

Objective To assess measures of puberty-presence of pubic hair, breast development, and menarche-for 3 racial/ethnic groups of girls in the United States. Methods Using data from the Third National Health and Nutrition Examination Survey, this study sample was restricted to 1623 girls aged 8 to 16 years (466 non-Hispanic white, 589 non-Hispanic black, and 568 Mexican American) for whom information was available on Tanner stages of pubic hair and breast development. Subsequently, the sample was restricted to 1168 girls aged 10 to 16 years (330 non-Hispanic white, 419 non-Hispanic black, and 419 Mexican American) for whom menarche data were available. Tanner stage II or higher was used to define pubic hair and breast development; menarche status was self-reported. The percentage of girls who had pubic hair and breast development and had achieved menarche was computed by age and race/ethnicity. Probit and failure time models were applied to estimate mean ages at onset of pubic hair, breast development, and menarche. The racial/ethnic differences also were examined after adjustment for social and economic variables and current body mass index. Results Black and Mexican American girls had pubic hair and breast development and had achieved menarche at younger ages than white girls. For example, 49.4% of black girls aged 9 years had breast development compared with 24.5% of Mexican American girls and 15.8% of white girls. The mean age at onset of pubic hair, breast development, and…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The age at puberty onset varies greatly between individuals, different ethnic populations, and between the sexes; girls on average experience the onset of puberty at younger ages than boys and are more likely to have idiopathic central precocious puberty, whereas boys are more predisposed to idiopathic delayed puberty.

  • There are substantial racial differences in sexual maturation; non-Hispanic black and Mexican-American ethnic origins are independently associated with earlier pubertal development in girls.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
