Psychotropic drug use among persons with mental distress symptoms: A population-based study in Norway

Abstract

Aims: To explore psychotropic drug use in the general population and in particular among non-institutionalized persons with mental distress symptoms. Methods: A total of 14,139 women and 11,665 men participating in the Oslo Health Study or the Oppland/Hedmark Study 2000—2001 submitted a self-administered questionnaire on health status and drug use, lifestyle, and socioeconomic factors. Respondents using antidepressants, hypnotics, and/or anxiolytics during the last four weeks were defined as users. A high Hopkins Symptoms Checklist-10 score indicated mental distress. The 15% with the highest score in each gender and age group (adults: 30/40/45 years; elderly: 60 years) were studied. Results: The prevalence of antidepressant use among those with mental distress was, for women: adults 21%; elderly 30%; and for men, adults 15%; elderly 15%. These figures were nearly four times higher than in the general population. Not participating in the labour market was the main factor associated with use of antidepressants for subjects with mental distress: adult women (odds ratio (OR) 3.5; 95% confidence interval (CI) 2.5—5.0); elderly women (OR 5.2; CI 2.7—10.2); adult men (OR 4.7; CI 3.0—7.3); and elderly men (OR 2.9; CI 1.4—6.0). Use of analgesics was the main factor associated with use of anxiolytics/hypnotics: adult women (OR 2.4; CI 1.7—3.4); elderly women (OR 2.3; CI 1.4—3.8); adult men (OR 2.1; CI 1.3—3.3); and elderly men (OR 3.4; CI 1.9—6.0). Conclusions: Among individuals with mental distress, not participating in the labour market and regular use of analgesics were the main factors associated with use of psychotropics in both genders regardless of age.
