Bold values are statistically significant. Notes: Information on educational level and marital status is missing for some individuals.
Models are harmonized to include the same variables among men and women, otherwise are non-significant variables excluded. Model 1 is age-adjusted, Model 2 age-adjusted and including all socioeconomic factors (educational level, marital status and neighbourhood socioeconomic status), Model 3 as Model 2 but also including depression and somatic comorbidity (i.e. cardiovascular disease and diabetes). (Model check revealed a significant interaction between age and CHF).
