摘要:
目的 采用国内外儿童青少年超重肥胖筛查标准,描述济南市儿童青少年超重和肥胖的流行现状,并对中国标准和国际标准进行比较分析,为有关部门制定干预策略提供基础数据。 方法 于2021年9—12月,使用2021年济南市746 985名中小学生健康体检身高、体重数据,计算体质量指数(BMI),描述济南市6~18岁儿童青少年超重和肥胖流行现状。通过计算加权Kappa值(Kw),比较中国标准、美国疾病预防控制中心(CDC)标准、国际肥胖问题工作组(IOTF)标准和世界卫生组织(WHO)标准的一致性。 结果 基于中国、美国CDC、IOTF、WHO标准,济南市6~18岁儿童青少年超重率分别为17.3%,16.5%,21.1%,13.6%,肥胖率分别为23.1%,19.5%,13.5%,6.6%。4种标准下,男生超重率和肥胖率均高于女生(中国:χ2值分别为1 418.48,9 868.51;美国CDC:χ2值分别为145.78,23 211.41;IOTF:χ2值分别为1 326.94,13 615.62;WHO:χ2值分别为873.13,46.41;P值均<0.01)。13~18岁年龄段青少年超重率高于6~12岁儿童(中国:χ2=29.13,美国CDC:χ2=6.43,IOTF:χ2=15.87,WHO:χ2=19.48,P值均<0.01);而6~10岁组肥胖率高于11~18岁组(中国:χ2=217.02,美国CDC:χ2=227.54,IOTF:χ2=171.91,WHO:χ2=165.91,P值均<0.01)。城镇儿童青少年超重率和肥胖率均略高于乡村儿童青少年(中国:χ2值分别为25.06,245.12;美国CDC:χ2值分别为56.13,205.93;IOTF:χ2值分别为182.34,22.04;WHO:χ2值分别为200.88,21.61;P值均<0.01)。中国标准与IOTF标准和美国CDC标准表现出较好的一致性,Kw值分别为0.72, 0.83;但与WHO标准的一致性较差,Kw值为0.33。 结论 济南市儿童青少年超重肥胖流行现状严峻。中国标准与IOTF标准、美国CDC标准一致性较好,与WHO标准一致性较差。 Abstract:Objective To describe the prevalence of overweight and obesity among children and adolescents in Jinan City according the national and international criteria, as well as to compare the Chinese and international standards, so as to provide basic data for relevant intervention strategies. Methods From September to December 2021, using the height and weight data obtained from the health checkup reports of 746 985 primary and secondary school students in Jinan City in 2021, body mass index(BMI) was calculated to evaluate the current status of the prevalence of overweight and obesity among this sample of children and adolescents aged 6-18 years old. The consistency of the Chinese standard, U.S. Centers for Disease Control and Prevention (CDC) standard, International Obesity Task Force (IOTF) standard, and World Health Organization (WHO) standard was compared by calculating the weighted Kappa value. Results Based on the Chinese, U.S. CDC, IOTF and WHO standards, the overweight rates of children and adolescents aged 6-18 years in Jinan were 17.3%, 16.5%, 21.1% and 13.6%, respectively, and the obesity rates were 23.1%, 19.5%, 13.5% and 6.6%, respectively. The overweight and obesity rates of boys were higher than those of girls under the four criteria (China: χ2=1 418.48, 9 868.51, U.S. CDC: χ2=145.78, 23 211.41, IOTF: χ2=1 326.94, 13 615.62, WHO: χ2=873.13, 46.41, P < 0.01).The overweight rate of adolescents in the 13-18 year-old age group was higher than that of children aged 6-12 years (China: χ2=29.13, U.S. CDC: χ2=6.43, IOTF: χ2=15.87, WHO: χ2=19.48, P < 0.01) and the obesity rate of the group aged 6-10 years was significantly higher than that of the group aged 11-18 years (China: χ2=217.02, U.S. CDC: χ2=227.54, IOTF: χ2=171.91, WHO: χ2=165.91, P < 0.01). The rates of overweight and obesity in urban children and adolescents were slightly higher than those in rural children and adolescents (China: χ2=25.06, 245.12, U.S. CDC: χ2=56.13, 205.93, IOTF: χ2=182.34, 22.04, WHO: χ2=200.88, 21.61, P < 0.01). The Chinese standard showed good agreement with the IOTF standard and U.S. CDC standard, with weighted Kappa values of 0.72 and 0.83, but poor agreement with the WHO standard, with a weighted Kappa value of 0.33. Conclusion The current prevalence of overweight and obesity among children and adolescents in Jinan is serious. The Chinese standard has good consistency with IOTF standard and American CDC standard, and poor consistency with WHO standard. -
