Note: All percentages are probability weighted to account for the National Health and Nutrition Examination Survey sampling design.
↵a Men responding “more active” to the question “Compared with most men your age, would you say that you are …” were considered to be physically active; those responding “less active” or “about the same” were considered not physically active.
↵b Included angina, heart attack, coronary heart disease, congestive heart failure, or stroke.
↵c Before the age of 50.
↵d Using World Health Organization classification: obese (body mass index [BMI] ≥30 kg/m2 or waist circumference [WC] ≥102 cm), overweight (BMI ≥25 kg/m2 but <30 kg/m2 or WC ≥94 cm but <102 cm), or normal weight or underweight (BMI <25 kg/m2 or WC <94 cm).
↵e Undiagnosed hypertension: average systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg; undiagnosed hypercholesterolemia: total cholesterol ≥6.21 mmol/L (≥240 mg/dL); undiagnosed diabetes: fasting plasma glucose level ≥126 mg/dL (≥7.0 mmol/L).
