Risk of depression onset across baseline levels of leptin by visceral fat.
a HRs and 95%CIs are adjusted for age, race, education level, alcohol consumption, smoking status, physical activity, 3MS score, number of chronic diseases, CVD, diabetes, visceral fat, (log)IL-6 and (log)CRP.
b Group: + v fat = high visceral fat (>195.5 cm2 in men and >165.9 cm2 in women); − v fat = normal visceral fat; + leptin = high leptin (>10.1 ng/mL in men and >28.9 ng/mL in women); − leptin = normal leptin.
