Note: All percentages are probability weighted to account for the National Health and Nutrition Examination Survey sampling design.
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.
Included angina, heart attack, coronary heart disease, congestive heart failure, or stroke.
Before the age of 50.
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).
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).
