Abstract: BACKGROUND: Little is known about the relationship between parkinsonism or Parkinson's disease (PD) and frailty in Latin America. OBJECTIVE: The study aimed to determine the cross-sectional and prospective associations between parkinsonism and PD with frailty in a large multi-country cohort in Latin America. Frailty was assessed using three different models to explore which definitions are more appropriate to screen for frailty in a PD population. METHODS: 12,865 older adults (aged ≥65 years) from the 10/66 population-based cohort study in six Latin American countries were analyzed. Logistic regression models assessed the cross-sectional association between parkinsonism/PD with baseline frailty. Individual country analyses were combined via fixed-effect meta-analysis. In non-frail participants who were followed up for 4 years, Cox proportional hazards regression models assessed the prospective association between parkinsonism/PD with incident frailty accounting for competing risk of mortality. RESULTS: At baseline, the prevalence of parkinsonism and PD was 7% and 2%, respectively, and the prevalence of frailty varied across the three models with rates of 18% for frailty phenotype, 20% for frailty index and 30% for multidimensional frailty model. PD was associated with baseline and incident frailty after accounting for age, sex, and education: odds ratios and 95% confidence intervals (95% CI) for frailty were 2.49 (95% CIs 1.87-3.31), 2.42 (95% CIs 1.80-3.25), and 1.57 (95% CIs 1.16-2.21), and cause-specific hazard ratios were 1.66 (95% CIs 1.07-2.56), 1.78 (95% CIs 1.05-3.03), and 1.58 (95% CIs 0.91-2.74). Similar results were found for parkinsonism. CONCLUSION: Parkinsonism and PD were cross-sectionally and prospectively associated with frailty in Latin America. Routine screening for frailty in PD patients may aid earlier detection of those at greater risk of adverse outcomes.
