中国6~17岁儿童青少年腰围水平及中心性肥胖流行特征

目的 分析我国6~17岁儿童青少年腰围水平及中心性肥胖流行特征。方法 利用"2010-2012年中国居民营养与健康状况监测"中6~17岁儿童青少年调查资料,分析儿童青少年腰围水平及中心性肥胖流行现状。利用腰围的P₉₀（同年龄、同性别）作为中心性肥胖的判断界值。结果 我国各年龄组儿童青少年腰围均为男生大于女生（P<0.000 1）,城市大于农村（P<0.05）,家庭收入水平高的儿童青少年大于中、低家庭收入儿童青少年（P=0.000 3）。6~17岁儿童青少年中心性肥胖率为11.2%,其中男生和女生分别为10.7%和11.8%,差异无统计学意义（P>0.05）。城市和农村男生的中心性肥胖率分别为13.2%和8.5%,女生分别为12.3%和11.2%。按家庭经济收入水平分,高、中、低家庭收入男生中心性肥胖率分别为15.8%、11.5%和8.8%,女生分别为13.5%、11.9%和11.6%。结论 男生的腰围较女生更易受城乡和家庭收入水平的影响。

Epidemiological characteristics of waist circumference and abdominal obesity among Chinese children and adolescents aged 6-17 years

Objective To analyze the epidemiological characteristics of waist circumference and abdominal obesity among Chinese children and adolescents aged 6-17 years.Methods Data was from the samples of aged 6-17 years in the China National Nutrition and Health Surveillance program in 2010-2012. P₉₀ (the same age, the same sex) was used as the diagnostic value for abdominal obesity.Results The overall waist circumference of children and adolescents in all the age groups appeared higher in males than that in females (P<0.000 1), higher in cities than that in the rural areas (P<0.05), and higher in children with high family income than those with middle or low family incomes (P=0.000 3). The rate of abdominal obesity in children and adolescents aged 6-17 years appeared as 11.2% on average and 10.7% and 11.8% for boys and girls, respectively but with no significant difference (P>0.05). Rates on abdominal obesity appeared as 13.2% and 8.5% for boys while as 12.3% and 11.2% for girls respectively, in urban or rural areas. As for the levels of family income, the abdominal obesity rates appeared as 15.8%, 11.5% and 8.8% respectively for boys while 13.5%, 11.9% and 11.6% respectively for girls, under high, middle and low levels of family income.Conclusion The rate of abdominal obesity in boys seemed more responsive to the impact of income in urban or rural areas.
