  1. CVD: Cardiovascular disease, HDL-C: High density lipoprotein cholesterol, Mean ± SD are shown for continuous variables and P value is calculated with t-test; % is shown for categorical variables with P value according to chi-square; TG and TG/HDL are shown as median (interquartile range) and P value according to Mann-Whitney test. For categorical variables with more than 2 values, the first category was considered as the reference and the p-value is for linear trend in risk. Obesity: BMI < 25 (normal), 25-29.9 (overweight) and ≥30 kg/m2 (obese), Abdominal obesity: waist circumference ≥90 cm in both sexes; Hypertension: Blood pressure ≥140/90 mmHg and/or taking of antihypertensive medication; IGT: 2-hours plasma glucose level between 7.77-11.1 mmol/l.
