Abstract: Objective To examine the relationship between obesity types and metabolic abnormality,and to provide scientific evidence for prevention and control of cardiovascular diseases in children and adolescents.Methods A total of 1 170 children and adolescents aged 7-17 years from urban area of Jinan were included in this study.Height,weight,waist circumference (WC) and blood pressure were measured,and the fasting plasma glucose (FPG),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),and low-density lipoprotein cholesterol (LDL-C) were also measured to analyze the relationship between different obesity types and metabolic disorders.Results There were statistical differences in various kinds of biochemical indicators (except for FPG and TC) and the prevalence of metabolism disorders (except for abnormal glucose metabolism) between three groups based on status of body mass index (BMI) and WC(P<0.05),significantly highest in the composite obesity group,moderate increased in general obesity or central obesity group,and lowest in normal BMI and WC group.Compared with normal BMI and WC group,the other two groups had higher risk of metabolic disorders.In predicting at least two metabolic disorders,for example,the odds ratio (OR) of general or central obesity was only 1.50(95%CI=0.78-2.90),the OR of composite obesity was 7.84(95%CI=5.00-12.30).Conclusion BMI and WC should be combined to determine obesity status in child and adolescent physical examination,more effectively prevent and control cardiovascular risk factors in this population.
