Psychotropic drug use among older adults: prevalence and associated factors.
Brazilian Journal of Epidemiology 2017 January
Objective:: Investigating the prevalence of psychotropic drug use among older adults and factors associated with it.
Methods:: This study was based on the Belo Horizonte Metropolitan Area Health Survey, conducted in 2003. It involved 1,635 elderly (60 years or older) citizens, who were residents of cities within the Belo Horizonte Metropolitan Area and were selected using complex randomize sampling. Logistic regression models were used to identify factors associated with psychotropic drug use, with a 5.0% significance level.
Results:: The prevalence of psychotropic drug use in the sample was 13.4%; specifically, 8.3% of individuals surveyed used benzodiazepines, whereas 5.0% used antidepressants. The following factors were independently associated with the use of psychotropic drugs: female gender (OR = 2.20; 95%CI 1.49 - 3.27), medical diagnosis of depression (OR = 6.42; 95%CI 4.31 - 9.55), 5 or more medical appointments in the last 12 months (OR = 2.15; 95%CI 1.32 - 3.53), and subscription to private health insurance (OR = 2.69; 95%CI 1.86 - 3.88).
Conclusion:: The prevalence observed was similar to the one verified in other elderly Brazilian populations and the pattern of associated factors was consistent with the one detected for older populations of higher-income countries. Medical diagnosis of depression was the factor most strongly associated with psychotropic drug use.
