a
Values are number (percentage) unless otherwise indicated. Sample size variations are due to incidental missing values in returned surveys; thus, not all values sum to total respondents.
b
Weighted and stratified χ2 tests were used to compare sexes and to generate P values.
c
Calculated as weight in kilograms divided by height in meters squared.
d
Waist circumference ≥120 cm for men and ≥88 cm for women.
