The use of antidepressants and introduction of new types in different socio-economic groups: A Danish registry-based cross-sectional study
ABSTRACT Danish registry-based studies have found socio-economic differences in drug use. The extent to which the use of antidepressants differs between socio-economic groups is unknown.
1) to examine the association between socio-economic status (SES) and use of antidepressants 2) to evaluate the introduction of new types of antidepressants.
A registry-based cross-sectional study linking information from administrative registries in North Jutland County, Denmark, 1995-99.
1) the prevalence proportion for use of antidepressants in different SES groups and by sex, and the estimated prevalence proportion ratio; 2) the proportion using the new drugs in different socio-economic groups through the study period.
Women used antidepressants more than twice as often as men with an increasing tendency for both men and women. The use of antidepressants was highest in persons outside the labour market. Among employees, the proportion using new types of antidepressants increased from 1% to 18%. High SES seemed to correlate to higher use of new antidepressants. The new antidepressants were introduced faster among men compared with women.
The study showed differences in purchase of antidepressants in different SES groups. Furthermore, it showed faster introduction of new antidepressants among men and employees with high SES.

ABSTRACT: To evaluate patient and physician characteristics associated with the type of psychotropic medications (anti-anxiety, antidepressant, or both) purchased. The Clalit Health Care Services is the largest managed care health fund in Israel, a country that employs a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 as of January, 2006. Overall, 2,217 purchased either antidepressant or antianxiety medications at least once during the year 2006 and had no prior purchases during the last quarter of 2005. The majority (1,518; 68.4%) purchased only anti-anxiety medications and as many as 264 (12%) purchased both anti-anxiety and antidepressant medications. The remaining 435 (19.6%) patients purchased only antidepressant medications. Physician level characteristics explained only a small portion of the variance and, thus, were not included in further analysis. Several patient level characteristics, including age, somatic, and psychiatric diagnosis were associated with the purchase of different types of medications. Contrary to clinical guidelines, the purchase of anti-anxiety medications is more prevalent than the purchase of antidepressant medications. In a managed care setting, patient characteristics have a greater role in determining purchasing patterns than provider characteristics; potentially, because of the managed care characteristics that actively guide the care provided to patients.The International Journal of Psychiatry in Medicine 01/2012; 44(1):91-102.

ABSTRACT: BACKGROUND: Various domains of socioeconomic circumstances are associated with self-reported mental health, but we lack evidence from studies using medically confirmed mental health outcomes. This longitudinal study aimed to examine the associations of multiple domains of socioeconomic circumstances with subsequent prescribed psychotropic medication among Finnish public sector employees. METHODS: Baseline survey data among 40-60-year-old employees of City of Helsinki were linked with Social Insurance Institution of Finland register data on psychotropic medication purchases (n=5563). HRs were calculated using Cox regression to examine associations of parental and own education, childhood and current economic difficulties, occupational class, household income and housing tenure with antidepressants, sleeping pills and sedatives and any psychotropic medication during a 5-year follow-up. RESULTS: In age and previous psychotropic medication adjusted models, the risk of antidepressant medication was higher in those with childhood (women: HR=1.29, men: HR=1.64) and current economic difficulties (women: HR=1.30-1.54), rented housing (women: HR=1.20, men: HR=1.45) and the second lowest income group (men: HR=1.71). Gradual adjustments had little effect on the associations. For sleeping pills and sedatives, similar associations were found in women for current economic difficulties, and in men for housing tenure. Results for any psychotropic medication reflected those observed for antidepressants. CONCLUSIONS: Past and present economic difficulties and housing tenure were more important determinants of subsequent psychotropic medication among employees than the conventional socioeconomic determinants. The associations were somewhat inconsistent between the medication groups and the sexes. The results support the importance of examining multiple domains of socioeconomic circumstances simultaneously.Journal of epidemiology and community health 04/2012; 66(12).
