Objective:To study the groups and influencing factors of metabolic syndrome in children and adolescents of Chongqing.Methods:According to the method of stratified cluster sampling, 4481 school-age children(including 2223 students in urban and 2258 students in rural) aged 7 to 16 years old were enrolled from 5 middle and primary schools (2 in urban and 3 in rural)of Chongqing to be studied through questionnaire, which include items on metabolic index and influencing factors. Children were divided into normal group,overweight group and obese group according to body mass index(BMI).To analysis the metabolic indices, Metabolic syndrome influencing factors were analyzed by logistic regression analysis and differences of them between boys and girls were compared.Results:(l)The total incidence of overweight among children and adolescents in Chongqing was 9.8%, of which the boy was 12.0%, the girl was 7.4%. The total incidence of obesity was 5.4%, of which the boy was 7.3%, the girl was 3.4%(P<0.05). (2)With the increase of BMI, systolic blood pressure(SBP), diastolic blood pressure(DBP), triglycerides(TG), cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C) and waist circumference(WC) have a tendency to increase, high-density lipoprotein cholesterol(HDL-C) has a tendency to decrease (P<0.05). (3)The overall rate of metabolic syndrome was 0.45%,of which Obese group had significantly higher prevalence (6.9%) compared with overweight group (0.5%) and normal weight group (0.0%) (P<0.05),in boys higher than in girls(P<0.05).The rate of individual MS component among obese children were:high WC(37.9%), high TG(22.7%), low HDL-C(19.7%), high non-HDL-C (7.4%), high blood pressure(BP)(4.4%), high fasting plasma glucose(FPG) (2.0%). (4)MS influencing factors logistic regression analysis demonstrated that WC,meat intake,family history of hyperlipidemia were risk factors.Boys had higherWC,ate more meat than girls(P<0.05).Conclusion:Boys had higher MS prevalence than girls in the overweight and obese children and adolescents of Chongqing. High WC, high TG, low HDL-C were the most common abnormal factors among obese children in Chongqing. High meat intake,family history of hyperlipidemia were the major risk factors of metabolic syndrome in children and adolescents of Chongqing. More attention is expected to be paid to Ms. |
