【Abstract】 Objective: To study the changes in body mass index (BMI) and evaluate feasibility of taking BMI as the standard measure of obesity during childhood. Methods: The skew distribution of BMI was adjusted with Cole’s LMS method. Results: There were sex differences in BMI, the changes in BMI were earlier among girls than among boys in the period of growth. Standardized percentile charts of BMI for children, birth～18 years, Xi’an, 1995, were presented in this paper. Conclusion: The obese children could be identified with BMI percentiles, percentile charts of BMI in the paper might be taken as references for assessing obesity of children in clinical practices.更多还原
