  1. BP blood pressure, CI confidence interval, HR hazard ratio. Adjusted variables were age, sex, body mass index (< 25 kg/m2 or ≥ 25 kg/m2), dyslipidemia (absence or presence), smoking status (never, current, quit), alcohol consumption (non-, moderate, heavy), physical activity (0, 1–59, ≥ 60 min/week), family history of diabetes, and fasting plasma glucose level. Dyslipidemia was defined as high-density lipoprotein cholesterol < 1.03 mmol/l and/or low-density lipoprotein cholesterol cholesterol ≥ 3.62 mmol/l and/or triglycerides ≥ 1.69 mmol/l
