MethodsBy random cluster sampling, 6 157 girls aged 6-18 were sampled. Their body weight, height, body fat percentage and secondary sex characteristics were measured. The total means of menarche age (MMA) were analyzed using the status method. The menarche ages of different nutritional status were analyzed using the retrospective method. All the subjects were divided according to underweight, normal weight, overweight and obesity. ResultsThe total incidence of overweight and obesity were 11.43% and 9.05%, respectively. The MMA were 12.19 years. The percentages of the menarche were higher for the overweight and obesity girls than that of the normal-weight girls. The menarche ages of the overweight/obesity girls were earlier than that of the normal-weight ones. Conclusion Closed association is found between the percentage of body fat and girls’ sexual development, especially that ofmenarche age. It’s important to control the occurrence of overweight and obesity in puberty for females’ health.
