Data are from logistic regression analysis. Model 1: adjusted for baseline age, smoking, alcohol consumption, cardiovascular disease, and NCEP metabolic risk sum. Model 2: adjusted for variables in model 1, the study groups, physical activity, and intake of saturated, monounsaturated, and polyunsaturated fatty acids, fiber, and carbohydrates. Model 3: adjusted for variables in models 1 and 2, body weight at baseline, and change in body weight during 2 years.

*In men: low <23.3, middle 23.3–29.1, and high >29.1 ml · kg⁻¹ · min⁻¹. In women: low <18.4, middle 18.4–22.8, and high >22.8 ml · kg⁻¹ · min⁻¹.
