Continuous variables are standardized (variables divided by their respective standard deviation. Original units: weight in kg; height in cm; mid-upper arm, waist, hip, and chest circumferences in cm; subscapular, suprailiac, and triceps skinfold thicknesses in mm; arm muscle and fat areas in cm2; and body mass index in kg/m2. Standardized by dividing variables by their respective standard deviation. Standardized unit = one standard deviation. Bold numbers indicate significant findings.
Odds ratios (ORs) adjusted for age in years (continuous), smoking history (never, former, or current smoker), income (below, within, or above the poverty line), and site (California/Utah).
In original units. Body mass index categories were defined as: underweight <18.5 kg/m2, normal weight 18.5–24.5 kg/m2, overweight 25–29.9 kg/m2, and obese ≥30 kg/m2.34
CI, confidence interval; OR, odds ratio.
