Factors associated with recurrent falls in a cohort of older adults

Abstract

Objective: To analyze the factors associated with recurrent falls in community-dwelling older adults from Cuiabá. Methods: This is an epidemiological, prospective, concurrent cohort study with a two-year follow-up. In-home surveys were conducted in 2012 and 2013. The data were treated by the software Epi Info and SPSS. Bivariate analysis investigated associations between risk factors and recurrent falls by calculating the relative risk (RR) of the cumulative incidences with a confidence interval of 95% (95%CI). Multiple analysis with Poisson regression included all variables with p < 0.20 in the crude analyses. The significance level of 5% (p < 0.05) was adopted as significant association for remaining in the final model. Results: Most older adults (77.6%) had recurrent falls. The variables significantly associated with recurrent falls were older adult’s income of up to two minimum salaries (RR = 1.62; 95%CI 1.04-1.77), absence of arthritis or arthrosis (RR = 1.32; 95%CI 1.10-1.48), having regular to very bad self-perceived health (RR = 1.44; 95%CI 1.12-2.04), and having visual impairment (RR = 1.23; 95%CI 1.01 -1.69). Conclusions: Falls in older adults are associated with low education levels, regular to very bad self-perceived health, visual impairment, and recurrent falls.
