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.
