RESUMO
Objective To investigate the prevalence of obesity and metabolic syndrome(MS)of children and adolescents in Longquan mountainous area in Zhejiang province.Methods A representative sample involving 2 135 children and adolescence aged 10 to 15 years were randomly surveyed and a total of 2 125 had available data(male/female ratios as:1 109/1 016).Using the standard methods,we measured the weight,height,waist circumference,hip circumference,blood pressure,detected fasting plasma glucose (FPG),high density lipoprotein cholesterol (HDL -C),triglyceride(TG),total cholesterol(TC),and calculated non-high density lipoprotein cholesterol(non-HDL). The prevalence of obesity and MS among the 10 to 15 years old children and adolescence in Longquan was compared with that in six cities in China(Beijing,Tianjin,Shanghai,Zhejiang,Chongqing and Guangxi).Results The preva-lence of obesity was 4.7% in 10 -15 -year -old teenage,in which the male obesity prevalence was 6.3%(70/1 109),female obesity prevalence was 3.0%(30 /1 016).The prevalence of overweight was 9.4% and the prevalence of boys was 11.0%,while the girl was 7.6%.The prevalence of obesity and overweight was 16.4%(299/2 125).The prevalence of MS was 2%(42/2 125)in the survey,but 42.0%in the obesity.The prevalence of obesity in Longquan(4.7%)was lower than that in the national six cities(8.1%)among the children and adoles-cents from 10 to 15 years old(χ2 =31.09,P=0.000).But in the obesity students,the prevalence of MS(42.0%)in Longquan was higher than that in six cities(28.8%)(χ2 =5.43,P=0.02).Conclusion The prevalence of obesity in Longquan mountainous area was lower than that in the national six cities among the children and adolescents from 10 to 15 years old.However,the prevalence of MS among the obesity in Longquan was higher than that in six cities.
