Clinical risk factor categories based on recommendations from the National Cholesterol Education Program, the American Diabetes Association, and the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (11-13).
Adjusted for sex. All values except those for BMI 25.0-29.9 and BMI ≥40.0 were significant at P < .001 (χ2 test).
Adjusted for age. All values except those for high total cholesterol, high triglycerides, fasting glucose 110-125 mg/dL, and fasting glucose >125 mg/dL were significant at P < .001 (χ2 test ).
BMI categories are not mutually exclusive. All of the participants who appear in the ≥40 category also appear in the ≥30 category.
