Values represent odds ratio (95% confidence interval) using logistic regression analysis; Model I included all independent variables except for depressive mood, while model II included all independent variables including depressive mood.

^aRHGS (Relative handgrip strength) was computed as summation of both hands-grip strengths divided by body mass index.

^bIllness was defined when there was any diagnosis for cardiovascular disease, osteoarthritis, rheumatoid arthritis, osteoporosis, depression, stomach cancer, colon cancer, and lung cancer.
