Purpose
Comorbidities, such as kidney disease (CKD), increase the likelihood of falls and fall-related injuries. Despite the focus of most research in this population on older adults, falls are a significant cause of injury throughout adulthood. Therefore, we aimed to describe the epidemiology of falls in middle-aged adults with kidney diseases.
Methods
We analyzed falls and fall-related injuries among middle-aged adults (45–65 years old) with and without CKD included in the 2014 Behavioral Risk Factor Surveillance System (BRFSS) utilizing multivariate logistic regression and complex sample survey data analysis procedures.
Results
Middle-aged adults with CKD were more likely to suffer a fall (2.30, 95% CI 2.07–2.55) and a fall-related injury (1.54, 95% CI 1.32–1.80) compared to those without CKD. However, only the increased likelihood for falls remained significant after correction for multiple demographic, health, lifestyle, and comorbid conditions (AOR 1.22, 95% CI 1.08–1.39). Among adults with CKD, general health status, smoking, and total comorbidity scores were significant predictors of falls and fall-related injuries (p < 0.05 for all). Furthermore, individual comorbidities such as COPD, asthma, depressive disorders, stroke, and arthritis also predicted falls and fall-related injuries (p < 0.05 for all).
Conclusion
Middle-aged adults with CKD were more likely than those without CKD to fall and suffer a fall-related injury. However, injury risk did not remain elevated after accounting for differences between groups. The presence of comorbidities, especially depressive disorders, was associated with increased odds for falls and fall-related injuries. Given the high prevalence of depression among adults with CKD, the relationship between depression and falls warrants further examination.
