Model 2: expanded Model 1 (covariates age, gender, education, living situation, general COVID-19 concern and functional disability only) by adding LPA, walking, exercise and ST as individual predictors for each dependent variable.

β represents the standardised beta coefficient and ΔR² represents the proportion of the variance that is explained by the addition of the predictor independent variable to the model relative to Model 1.  β coefficients for covariates were broadly similar as those reported in Table 1. Therefore, to improve readability, β's are only reported for the associations between the independent variables (LPA, walking, exercise, ST) and the dependent variables. Full information of all Model 2 regressions, including the 95% CI intervals to determine significance, F-value with associated p-values and the β for each covariate are reported in Supplementary Tables S1-S4
