Aim: To analyze the relationship between polypharmacy and variables as frailty and other chronic comorbidities in Chilean older adults.
Design: Cross-sectional study.
Participants: One thousand two hundred and five older adults aged 65 and older.
Methods: The presence or absence of frailty syndrome was determined according to Fried criteria. Data collection was made through questionnaires conducted by an interview.
Results: The prevalence of polypharmacy was 37.59%. The prevalence of hyperpolypharmacy was 2%. Increased prevalence of frailty was demonstrated regarding the progression of the state of polypharmacy. When analyzing the contribution of frailty respect polypharmacy condition, frail state, nutritional risk and obesity are founded as a factor associated with polypharmacy. Regarding chronic disease, hypertension (OR: 8.039, p< 0.0001), type 2 diabetes (OR: 4.001, p< 0.0001) and respiratory diseases (OR: 2.930, p< 0.0001) were associated to polypharmacy. It was found a strong and significant positive correlation between polypharmacy prevalence and frailty score (polypharmacy condition, Spearman R: 0.89, p=0.033; hyperpolypharmacy condition, Spearman R: 0.94, p=0.016). When analyzing the contribution of the polypharmacy to the presence of frailty, polypharmacy condition (OR: 1.510, p< 0.05), cognitive impairment (OR: 3.887, p< 0.001), obesity (OR: 1.560, p< 0.01) and nutritional risk (OR: 2.590, p< 0.001) are associated to frailty.
Conclusion: Frailty and chronic conditions as nutritional risk, obesity, hypertension, type 2 diabetes and respiratory disease are an important risk factor for the development of polypharmacy in Chilean older adults. Likewise, polypharmacy condition was observed to be a risk factor for frailty, demonstrating the bidirectional relationship between both conditions. Frailty syndrome evaluation in Chilean older adults could be an important alternative for polypharmacy prevention.
