Abstract: Objective To identify the association between pubertal timing and body fat content and distribution among children in Zhengzhou. Methods Using the cross-sectional survey method,7~18 years old students were selected from four urban schools and five rural schools.By means of physical examination and the examination of secondary sexual characteristics development,5 140 samples were available. Results The number of boys in early-timing pubertal group was 286(13.0%),and 1 052(47.9%) boys were grouped into on-time pubertal group.The number of girls in early-timing pubertal group and on-time pubertal group was 301(11.8%) and 1 174(46.2%),respectively.The overweight(with obesity) detection rate of boys in early-timing pubertal group was higher than that in on-time pubertal group (χ2=35.372,P<0.001).The same was true of girls (χ2=31.485,P<0.001).Body fat percentage and waist-hip ratio of boys and girls in early-timing pubertal group were higher than those in on-time pubertal group,the differences were statistically significant. Conclusion Excessive body fat content and body fat distribution are related to the early pubertal timing of children.

Key words: pubertal timing, sexual development, obesity, children

摘要: 目的 探讨郑州市儿童青春发动时相与体脂含量及分布的关系,为青春发动机制的研究提供依据。方法 采用横断面调查方法,选取郑州市4所城市学校、5所乡村学校7~18岁中小学生5 140名进行体格检查和第二性征发育检查。结果 男生青春发动时相提前组286名(13.0%),正常组1 052名(47.9%);女生青春发动时相提前组301名(11.8%),正常组1 174名(46.2%)。男生青春发动时相提前组超重(合并肥胖)检出率高于正常组(χ2=35.372,P<0.001);女生提前组超重(合并肥胖)检出率也高于正常组(χ2=31.485,P<0.001)。男女生青春发动时相提前组的体脂百分比、腰臀比均高于正常组,差异有统计学意义。结论 体脂含量过多及体脂分布与儿童青春发动时相提前有关。
