Data presented as mean, standard deviation or their corresponding 95% confidence interval (95% CI). a indicates pre–post differences within each group (intervention or control). BMI, body mass index; GDS, Geriatric Depression Scale, short form; β, beta coefficient of the intervention group, estimated from the regression model. Models were adjusted by baseline values of the specific outcome, baseline BMI value, follow-up period, age, gender and age-adjusted Charlson Comorbidity Index
