Values are expressed as odds ratios (with 95% confidence intervals).

Model 1, adjusted for age; Model 2, adjusted for age, body mass index, and total energy intake; Model 3, adjusted for all items in model 2 plus smoking status, alcohol consumption, physical activity, educational level, household income, and history of comorbidities; Model 4, adjusted for all items in model 3 plus serum creatinine, high-sensitivity C-reactive protein, total cholesterol, high-density lipoprotein cholesterol, and triglycerides levels.

*Dietary protein intake status was classified as low (<0.8 g/kg body weight/day), moderate (0.8–1.2 g/kg/d), and high (>1.2 g/kg/d) protein intake. Possible sarcopenia was defined as a handgrip strength <28 kg for men and <18 kg for women.
