Results for those aged 60–64 years are not presented because they are based on responses from <30 participants.
*Metabolic syndrome status could only be determined for 963 participants (390 men, 573 women) having complete data for the five components.
†Raised fasting blood glucose (≥100 mg/dL or previously diagnosed type 2 diabetes).
‡Raised BP (systolic BP≥130 or diastolic BP≥85 mm Hg or treatment of previously diagnosed hypertension).
§Raised triglycerides (≥150 mg/dL or specific treatment for this lipid abnormality).
¶Reduced HDL cholesterol (<40 mg/dL in men; <50 mg/dL in women or specific treatment for this lipid abnormality).
**Abdominal obesity (waist ≥102 cm in men or ≥94 cm in women or BMI≥30 kg/m2).
BMI, body mass index; BP, blood pressure; HDL, high-density lipoprotein.
