OBJECTIVE: To study the prevalence and family factors on metabolic syndrome( MS) in children and adolescents for Chongqing City.

METHODS: Multi-stage cluster sampling was used to recruit 1309 children and adolescents between 10 and 17 years old for physical examination( height, weight, waist circumference and blood pressure), blood biochemical examination( fasting plasma glucose, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol)and questionnaire for family factors( breast feeding, delivery mode, birth weight, education of parents, height and weight of parents, family history of hypertension and diabetes, and so on). MS was diagnosed by the definition of metabolic syndrome and prophylaxis and treatment proposal in Chinese children and adolescents.

RESULTS: The prevalence of MS on children and adolescents in Chongqing city was 5. 5%, and among normal weight, overweight, and obese groups were 0. 6%, 13. 8% and 41. 2%, respectively. Univariate analysis showed BMI of father( χ~2= 8. 237, P = 0. 016), BMI of mother( χ~2= 8. 978, P = 0. 011), occupation of father( χ~2= 7. 742, P = 0. 021), occupation of mother( χ~2= 6. 578, P = 0. 037) and family history of hypertension( χ~2=7. 684, P = 0. 006) were associated with MS. Logistic regression analysis showed father's overweight( OR = 1. 956, 95% CI 1. 176-3. 254), mother's obesity( OR = 2. 934, 95%CI 1. 230-6. 999) and family history of hypertension( OR = 1. 867, 95% CI 1. 139-3. 059) were risk factors for MS.

CONCLUSION: The detection rate of MS on children and adolescents in Chongqing city is higher, and the mainly risk family factors are father's overweight, mother's obesity and family history of hypertension.
