  • Bold font is used to show statistically significant results. Model 1 was a null model that included only receipt of public welfare assistance. Model 2 additionally included age and sex. Model 3 included the same variables as in model 2 and the number of household members, education and equivalent household income. Model 4 included the same variables as in model 3 and depressive symptoms. The fully adjusted model 5 had the same variables as in model 4 and IADL and medical conditions. To adjust for geographical variation, the individual municipalities were coded as dummy variables and included in the analysis.
