Note. OR = odds ratio; CI = confidence interval. We assessed mental and substsance use disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition14 with version 3.0 of the WHO Composite International Diagnostic Interview, a fully structured, lay-administered diagnostic questionnaire used in face-to-face interviews.15 Drug abuse with dependence disorder category was omitted because of insufficient lifetime cases (n < 30) but included in the “any substance-use disorders” category.
aReference category is age 45–65 years.
bGroups in this row were collapsed.
cGender was used as a control variable in the model except for drug abuse (because of insufficient cases of women).
