ABSTRACT

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.
