c

Body Mass Index, estimates were calculated from self-reported weight and height. Underweight indicates BMI < 18.5, normal indicates 18.5 ≤ BMI < 25, overweight indicates 25 ≤ BMI < 30, and obesity indicates BMI ≥ 30.

d

Dietary Approaches to Stop Hypertension score, ranged from 7 to 35, with a higher score indicating a healthier diet. DASH score was divided into quartiles based on the following ranges: Q1, 7-17; Q2, 18-20; Q3, 21-24; and Q4, 25-35.

e

Cardiometabolic disease includes hypertension, diabetes, stroke, and coronary heart disease.

f

Total physical activity (MET-hours/week) includes vigorous MPA (9 MET), moderate MPA (4.5 MET), and mild MPA (3 MET).
