Age and sex were kept in the models as potential confounding factors. Results PP and PIM use presented prevalence rates of 23.9 and 24.8%, respectively. PP was associated with body mass index, coronary heart disease, diabetes mellitus, and a number of comorbidities, whereas PIM use was associated with PP. Conclusion The prevalence rates of PP and PIM use found were lower than those reported in previous studies. This could be a result of differences in availability of drugs or prescribing habits. Multiple chronic diseases were associated with PP. These results suggest that more care should be taken in prescribing for the elderly population.
