To test the hypothesis that age at menarche is inversely related to body mass index (BMI).
A questionnaire was filled in by 11,293 young women at the time of discharge from compulsory military service, in order to determine the self-reported age at onset of menarche. The participants were weighed and measured and BMI was calculated. Obesity was defined as BMI >30 and leanness as BMI <20.
The age at menarche was significantly and inversely correlated with BMI (R = -0.11, p <0.001). The age at menarche of obese women (12.9+/-1.3 years) was significantly lower than that of non-obese, non-lean women (13.3+/-1.4 years), who themselves had a lower age at menarche than lean women (13.5+/-1.4 years) (p <0.001).
We conclude from our data that the relationship between BMI and pubertal development in girls appears to be a continuum.
检验初潮年龄与体重指数（BMI）呈负相关这一假设。
11293名年轻女性在义务兵役退伍时填写了一份问卷，以确定她们自我报告的初潮年龄。对参与者进行了称重和测量，并计算了BMI。肥胖定义为BMI>30，消瘦定义为BMI<20。
初潮年龄与BMI显著负相关（R = -0.11，p <0.001）。肥胖女性的初潮年龄（12.9±1.3岁）显著低于非肥胖、非消瘦女性（13.3±1.4岁），而非肥胖、非消瘦女性的初潮年龄又低于消瘦女性（13.5±1.4岁）（p <0.001）。
我们从数据中得出结论，女孩的BMI与青春期发育之间的关系似乎是一个连续体。
