The occurrence of abnormal FLI in groups classified according to alcohol use, smoking and physical activity as risk factors in men and women as follows: Alcohol consumption, 0 = no consumption; 1 = alcohol consumption 1–14 (men) or 1–7 (women) drinks/week; 2 = alcohol consumption exceeding 14 drinks (men) or 7 drinks (women) per week Smoking, 0 = no smoking, 1 = 1–19 cigarettes/day, 2 = ≥ 20 cigarettes/day. BMI, 0 = BMI < 25; 1 = BMI ≥ 25 and < 30; 2 = ≥ 30. Physical activity, 0 = physical activity more than 4 h/week; 1 = physical activity 0.5–4 h/week; 2 = physical activity less than 30 min/week. The sum of the scores yielded a total risk factor number, with higher scores indicating an unhealthier lifestyle (maximum = 6)
