摘　　要：目的探讨儿童早期至青春期体质指数变化对月经初潮的影响。方法采用随机整群抽样的方法,对无锡市4所小学队列人群进行随访,调查月经来潮情况,测量身高、体重。结果儿童早期超重或肥胖的检出率为10.09%,其中69.23%青春期仍然超重或肥胖;儿童早期BMI正常人中,青春期超重或肥胖的为9.4%。两时期BMI均正常(A0B0)来潮率最低为36.97%,两时期BMI均超重或肥胖(A12B12)来潮率最高为69.14%。二元logistic回归模型表明:儿童早期至青春期持续超重或肥胖,月经初潮来潮率是两时期BMI均正常儿童的4.170倍。青春期超重或肥胖,儿童早期超重或肥胖,月经初潮来潮率分别是两时期BMI均正常儿童的2.267倍和3.317倍。结论儿童早期体质因素对月经来潮的影响较大。在关注青春期体质因素的同时,更要预防儿童早期的超重或肥胖。Objective To explore the effect on menarche contribute to body mass index （BMI） changes from younger chil- dren to adolescent. Methods Information on the age at menarche, body height and body weight were obtained from 4 primary schools＇ cohort population, who were surveyed by random cluster sampling in Wuxi. Results At the baseline study, the preva- lence rate of overweight and obesity was 10.09% in younger children, of whom 69.23 % were kept overweight or obesity in ad- olescent. Those younger children whose BMI were normal, 9.4% of them were overweight or obesity in adolescent. The oc- currence rate of menarche in girls who had a normal BMI in both early childhood and adolescent was 36.97%, while in girls who were persistent overweight or obesity in early childhood and adolescent was 69.14%. Logistic regression analysis sugges ted that girls who were overweight or obesity in early childhood, and persistent overweight or obesity in adolescent, were more likely to have menarche （OR=4. 170） by comparison with those who had a normal BMI in early childhood and adolescent; in the meantime, girls whose MBI was normal in childhood but became overweight or obesity in adolescent （OR=2. 267） or who had a overweight or obesity in early childhood but normal in adolescent （OR= 3. 317） , which showed significant higher than those with a normal BMI on occurrence rate of menarche. Conclusion In all, BMI of younger children influenced menarche greater than other risk factors, so more emphasis should be paid on prevention overweight or obesity in younger children.
