- Data are presented as odds ratio (95% confidence interval)
- Model 1 adjusts for demographic factors (age, sex, race/ethnicity, poverty index). Model 2 adjusts for Model 1 factors + cardiometabolic factors (systolic blood pressure, heart rate, triglycerides, body mass index, truncal fat mass, high density lipoprotein, alanine aminotransferase, diabetes status, serum creatinine, albuminuria, smoking, alcohol consumption). Model 3 adjusts for other examination factors (leg fat parameters other than main predictor, arm fat parameters other than main predictor). Lean/fat ratio and fat % variables were not included in the same model due to significant correlation and high variance inflation factor. % Total fat in lower extremities corresponds to leg/total %, leg lean mass/fat mass ratio corresponds to leg lean/fat ratio, % fat in total leg mass corresponds to leg fat %. Identical for arm measures. Tertiles are as follows: leg/total % (female: < 36, 36–41%, ≥41%; male: < 31.5, 31.5–36.0%, ≥36%); leg lean/fat ratio (female: < 1.1, 1.1–1.4, ≥1.40; male: < 2.3, 2.3–3.0, ≥3.0); leg fat % (female: < 40, 40–45%, ≥45%; male: < 24, 24–29%, ≥29%)
