All values are means± SD. ANOVA for significance across columns was P<0.0001 for all variables except fish intake by physical activity.
Physical activity was <2 km/d for the lowest category, 2–4 km/d for the low category, 4–6 km/d for the intermediate category, 6–8 km/d for the high category, and >8 km/d for the highest category.
Cardiorespiratory fitness was <3 m/s for the lowest category, 3–3.5 m/s for the low category, 3.5–4.0 m/s for the intermediate category, 4.0–4.5 m/s for the high category, and >4.5 m/s for the highest category.
BMI (in kg/m2) was <20 for the lowest category, 20–22.5 for the low category, 22.5–25 for the intermediate category, 25–27.5 for the high category, and >27.5 for the highest category.
