目的探讨身高和体重的长期趋势对中国儿童青少年超重和肥胖患病率的影响。超重/肥胖被定义为按世界卫生组织(WHO)参考值的年龄BMI Z得分。结果2010年中国儿童超重/肥胖率男生为20.2%，女生为10.7%，7岁时各性别、各年龄段超重/肥胖率均呈上升趋势。在正常体重的男孩和女孩中，害羞和主观幸福感分别显著高于主观幸福感和主观幸福感(P<；0.001)。在超重/肥胖的男孩和女孩中，害羞显著低于主观幸福感(P<；0.001)，并在12岁以后呈现明显的下降趋势。在7-8岁超重的男孩和7-9岁的女孩中，SHA低于SWA。正常体重组的Shy/SHW和SHA/SWA大于超重组和肥胖组(P<；0.001)。结论中国儿童超重/肥胖率的持续上升可能与9岁前体重快速增长和12岁后身高没有长期增长有关。
Objective To explore the influence of secular trends in body height and weight on the prevalence of overweight and obesity among Chinese children and adolescents.Methods The data were obtained from five cross-sectional Chinese National Surveys on Students' Constitution and Health. Overweight/obesity was defined as BMI-for-age Z-score of per the Wold Health Organization (WHO) reference values. Body height and weight for each sex and age were standardized to those reported in 1985 (standardized height: SHY; standardized weight: SWY) and for each sex and year at age 7 (standardized height: SHA; standardized weight: SWA) using the Z-score method.Results The prevalence of overweight/obesity in Chinese children was 20.2% among boys and 10.7% among girls in 2010 and increased continuously from 1985 to 2010. Among boys and girls of normal weight, SHY and SHA were significantly greater than SWY and SWA, respectively (P < 0.001). Among boys and girls with overweight/obesity, SHY was significantly lower than SWY (P < 0.001), and showed an obvious decreasing trend after age 12. SHA was lower than SWA among overweight boys aged 7-8 years and girls aged 7-9 years. SHY/SHW and SHA/SWA among normal-weight groups were greater than among overweight and obese groups (P < 0.001).Conclusion The continuous increase in the prevalence of overweight/obesity among Chinese children may be related to a rapid increase in body weight before age 9 and lack of secular increase in body height after age 12.
