Logistic regression models; Odds ratio (OR) and 95%CIs of MetS and MetS component for Beijing adolescents aged 10–18 years according to the degree and type of obesity, subsample* of BCAMS population (n = 3814).

Abbreviation: HDL-C, high-density lipoprotein cholesterol; IFG, impaired fasting glucose; TG, triglyceride; BP, blood pressure; MetS, metabolic syndrome.*Within the whole BCAMS sample, a subsample of 3814 children aged 10–18 years was recruited for venipuncture blood samples.aDegree of obesity was diagnosed based on International Obesity Task Force (IOTF) BMI cutoffs; normal weight subjects were used as reference group; all models adjusted for age and gender.bType of obesity was diagnosed simultaneously by IOTF-BMI criteria and the age-,sex-specific waist circumference references for Chinese children and adolescents; subjects who were neither general obesity nor central obesity were used as the reference group; all models adjusted for age and gender.cMetS and its components were diagnosed according to the IDF criteria for adolescents: For adolescents aged 10∼15, MetS was diagnosed with central obesity (waist circumference ≥90th percentile for age and gender by the Chinese reference; and the presence of any two of the following four factors, ie: elevated BP (systolic ≥130/diastolic ≥85 mmHg), low HDL-C (#None had the MetS component.
