1 Adjusted for educational level (primary, middle and high), logarithm of income, smoking (yes/no), drinking (current drink or no) , physical activity (light, moderate and heavy), localization (urban or rural; north or south), total energy intake and fat share.
2 Metabolic syndrome was defined as the presence of three or more of the following components: (1) abdominal adiposity (WC ≥ 102 cm in men and ≥ 88 cm in women; (2) low serum HDL-cholesterol <40 mg/dL for men and <50 mg/dL for women); (3) high serum triglyceride levels (<150 mg/dL); (4) elevated blood pressure (SBP ≥130mmHg or DBP ≥ 85 mmHg); and (5)abnormal glucose homeostasis (fasting plasma glucose level ≥100 mg/dL).
3 Young is defined as ≤ 45 y
4 Adult is defined as <45 y and ≤ 60 y
5 Old is defined as <60 y
6 Values are ORs (95%CI) unless otherwise indicated.
