Self-medication and adherence to drug treatment: assessment of participants of the Universidade do Envelhecer (the University of Aging) program

Abstract Objectives : to evaluate the use of medication (for continuous use and self-medication) and adherence to treatment among elderly and non-elderly participants of the Universidade do Envelhecer (UniSer). Method : an observational, quantitative and cross-sectional study, using the interview technique, was carried out at UniSer with 215 subjects. A structured instrument was used for the collection of sociodemographic variables and self-medication data. The 1986 Morisky-Green-Levine Scale (MGL) and the Brief Medication Questionnaire (BMQ) regimen screening tool were used to assess adherence. Descriptive analyzes of the data were performed, and the chi-squared Test and Fisher’s Exact Test were applied to evaluate the association between variables of interest. Results : of the participants, 127 (59.1%) were elderly (< 60 years old), of whom 81.9% were women. Regarding self-medication, 22.9% of elderly and 21.7% of non-elderly persons practiced it in the previous seven days (p=0.848), even if they considered it dangerous (p=0.472). A total of 45.8% of the elderly and 55.6% of the non-elderly irrationally self-medicated within the analyzed period, while 76.4% of the elderly and 64.8% of the non-elderly used medications of continuous use (p=0.063). A total of 78.8% of the elderly and 76.1% of the non-elderly were not adherent to treatment (p=0.719) according to the MGL scale, while the BMQ Regimen Screen found that 36.7% of the elderly and 41.1% of the non-elderly were not adherent (p=0.595). Conclusion : these findings demonstrate that there were no significant differences between the groups studied and health education actions should be carried out with an emphasis on guidelines on adherence and the rational use of medicines
