Background and Purpose: The elderly population is more prone to chronic diseases, leading to polypharmacy, influenced by various factors. This study examined the relationship between education, socio-economics, and polypharmacy.
Materials and Methods: As part of the initial phase of a cohort on the health status of the elderly in Amirkola City (northern Iran) initiated in 2011, this descriptive-analytical study, conducted in 2023, involved individuals aged 60 and above. A total of 400 elderly participants were selected through stratified random sampling. Data were collected from the cohort database via demographic, medication, and medical history questionnaires. Data were analyzed using SPSS software, version 23, employing descriptive statistics, ANOVA, and chi-square tests at a significance level of 0.05.
Results: In this study, 400 elderly individuals with an average age of 68.18±7.11 years participated. The average number of medications used was 3.80±0.04. No significant association was found between education and polypharmacy (P=0.127). However, increased education was associated with a decrease in polypharmacy. The highest medication usage (4.46±3.27) was observed among the illiterate elderly. No significant association was identified between education and polypharmacy when considering gender, occupation, income satisfaction, and marital status (P>0.05); however, the majority of individuals experiencing polypharmacy were men, housewives, or retirees, those with low-income satisfaction, and married individuals.
Conclusion: The level of education had no significant relationship with polypharmacy when considering socio-economic factors, despite the fact that more literate elderly individuals had less polypharmacy. Conducting studies to further evaluate the cause of the lack of association between education level and polypharmacy could help in evidence-based decision-making.
