Polypharmacy And Cognition Function Among Rural Adults
JOURNAL OF ALZHEIMERS DISEASE(2021)
摘要
Background: Polypharmacy (using >= 5 medications) is associated with poor health outcomes. Mixed results from past studies surrounding chronic medication use, control of chronic conditions, and their effects on cognitive performance warrant further attention.Objective: Investigate a link between polypharmacy and cognition function in rural-dwelling adults in Texas, USA.Methods: Project FRONTIER (Facing Rural Obstacles to Healthcare Now Through Intervention, Education & Research) is a cross-sectional epidemiological study using community-based participatory research in three counties of Texas. Residents age > 40 were eligible for inclusion. The primary outcome is cognitive impairment, and exposures of interest are polypharmacy; comorbidities; and diabetes, hypertension, and depression medication. Logistic regression was used to assess association.Results: Six hundred eighty-nine individuals participated; the mean age was 61, and the majority were female (68.7%).The median number of medications taken by participants was 3.3 (IQR: 0-5); the rate of polypharmacy was 29.6%. Anti-hypertensive agents were the most common medications (15%) used. Polypharmacy users were 2.84 times more likely to have cognitive impairment [OR: 2.84, 95% CI (1.32-6.09)] than those using < 5 medications. Participants on hypertensive medications had 1.85 times higher odds [OR: 1.85, 95% CI (1.14-3.01)] of having cognitive impairment than those who did not have cognitive impairment.Conclusion: Polypharmacy increases the odds of cognitive impairment. The odds of presenting with cognitive impairment increased as the number of medications increased. Additionally, we identified a large, concerning number of participants with pharmacotherapy and poor chronic disease management. A larger study should examine medication adherence among rural elders to manage chronic disease and any healthcare barriers to adherence.
