SCL-10 = Symptoms checklist 10; ten items scale for measuring mental health status/psychological distress, CI = confidence interval
*Age per 10 years (centered according to mean age 43 years), level of education was coded 0–4 with 4 as the highest educational level, living conditions; unstable situation homeless or non-permanent residence, worrying debt situation: including any legal or illegal fees and debt, injecting substance use: during last 12 months
