| 目的 了解宁波地区7岁以下儿童单纯性肥胖发生情况, 探讨BMI不同参照标准在儿童超重、肥胖筛查的应用. 方法 随机整群抽样调查64 038名儿童的身高、体重, 按WHO 2006年推荐的身高标准体重值, 体重达身高标准体重≥10%为超重、≥20%为肥胖, 剔除伴肥胖的遗传性疾病和内分泌疾病. 并分别采用WHO与国际肥胖工作组(IOTF)推荐的超重、肥胖BMI参照值对同一人群计算超重、肥胖检出率. 结果 按WHO身高标准体重值宁波市7岁以下儿童超重和单纯性肥胖检出率分别为4. 25%和2. 88%, 其中男童分别为4. 45%和3. 01%, 女童分别为3. 86%和2. 56%, 男童与女童的超重和肥胖检出率差异有统计学意义(P<0. 01). 儿童超重和肥胖检出率随年龄增长而逐渐上升, 6岁时男童分别达到11. 84%和9. 68%、女童分别达到10. 14%和9. 46%. 不同年龄组和性别超重/肥胖比在1. 15～1. 94:1之间. 调查人群BMI的P85、P95均低于WHO与IOTF标准中"超重"、"肥胖"的BMI判断界值, 使用WHO与IOTF推荐的BMI参照值宁波市7岁以下儿童超重、肥胖检出率分别为9. 72%、2. 83%和6. 11%、0. 55%. 结论 儿童早期是预防日后肥胖的关键时期, 男童是预防和控制肥胖发生、发展的重点人群, 应将预防和控制儿童肥胖工作列入儿童保健服务之中, 建议尽快建立适合中国7岁以下儿童超重、肥胖筛查的BMI参考值. |

| Objective To investigate the occurrence of simple obesity among children under age 7 in Ningbo and to analyze the data regarding body mass index(BMI)from overweight screening under different standards. Methods Randomized cluster sampling was adopted and 64 038 children under 7 years old in Ningho were chosen and their length/height and weight were measured but pathological and secondary obesity cases were excluded. According to the Standardized Height and Weight set by WHO, more than 10% referring to overweight and more than 20% referring to obesity. Moreover, Results of this study were compared with growth standards with WHO's 2006 and IOTF standards. Results According to the Standardized Height and Weight set by WHO, the prevalence rates of overweight and obesity of children under age 7 were 4. 25% and 2. 88%. The ratio for boys were 4. 45% and 3. 01%, while for girls as 3. 86% and 2. 56%, with significant difference(P<0. 01). Data showed that the rates for overweight and obesity increased along with age, reaching 11. 84% and 9. 68% for boys and 10. 14% and 9. 46% for girls at the age of 6. The ratios of overweight/obesity among different age groups and sex were 1. 15-1. 94:1. The critical value for P85, P95 were lower than the standards set by WHO and IOTE The rates for overweight and obesity for latter were 9. 72%, 2. 83% and 6. 11%, 0. 55% respectively. Conclusion Early childhood is the key period for obesity prevention, with boys in particular. Prevention and control for childhood obesity should be included in the programs for children's health. Value of classification standards for the BMI screening of overweight and obesity for children under age 7 should be established in no time. |
