Correlation between overweight,obesity and metabolic syndrome in adolescents

Objective: To analyze the features of metabolic syndrome (MS) in adolescents,and to explore the correlation between obesity and MS so as to prevent obesity and MS in children. Methods: Nine hundred twenty-one students aged from 7-18 were selected from the primary schools and middle schools in Bengbu city. The height,weight,waist circumference,hip circumference,blood pressure, TC,TG,HDL-C,LDL-C,FPG,UA and hs-CRP of the children were measured and compared. Results: MS was detected in 128 of the students. Among them,three cases were in the normal weight group(0.9%),30 in the obesity group(11.9%) and 95 in the overweight group(28.4%). The difference was significant among the three groups(P < 0.01). The rate of MS differed significantly between the male and the female students(P < 0.01). The prevalence of high blood pressure,central obesity,WHR,WHtR,low HDL-C,high TG and high FPG in the overweight group and the obese group were significantly higher than that in the normal weight group (P < 0.05-P < 0.01). The FPG and TC had no significant differences between the over -weight group and the normal group(P > 0.05),while other factors were significantly different among the three groups(P < 0.05-P < 0.01). Conclusions: The prevalence and risk factors of MS increase along with the rise of body weight in the adolescents.
