All models are adjusted for age, education, marital status, income, BMI, fat mass, lean mass, alcohol intake, smoking, nutritional status, frailty, thyroid disease, arthritis and calcium, by backward elimination (with predictor retained if p<0.2). Statistically significant associations (p<0.05) are highlighted in bold and the trends are in italics. SB, sedentary behavior; LPA, light physical activity; MVPA, moderate-to-vigorous physical activity.
