* Data are odds ratios (95% confidence interval) of poorer physical performance (lower three quartiles of gait speed, six-minute walk distance, summary performance score and hand grip strength and higher three quartiles of timed up and go) with respect to the best performance (highest quartile of gait speed, six-minute walk distance, summary performance score and hand grip strength and lowest quartile of timed up and go), and are adjusted for age, marital status, education level, smoking status, alcohol intake, physical activity, body mass index, metabolic syndrome, hypertension, diabetes mellitus, stroke, cardiovascular disease, arthritis, chronic kidney disease, cancer, lung disease, depressed mood, dietary intake of energy, protein, vitamin A, vitamin E, vitamin C, vitamin B6 and vitamin B12.
