Association between self-reported visual symptoms (suggesting cataract) and self-reported fall-related injury among adults aged ≥65 years from five low- and middle-income countries

<p>Background</p> <p>Cataracts may increase risk for falls but studies on this topic from low- and middle-income countries (LMICs) are scarce. Therefore, we examined the cross-sectional association between self-reported visual symptoms (suggesting cataract) and self-reported injurious falls in nationally representative samples of adults aged ≥ 65 years from five LMICs (China, Ghana, India, Mexico, and Russia).</p> <p>Methods</p> <p>Data from the WHO Study on global AGEing and adult health (SAGE) were analysed. Self-reported information on past 12-month fall-related injury and cataract based on symptoms were collected. Multivariable logistic regression and meta-analyses were conducted to assess associations.</p> <p>Results</p> <p>Data on 13,101 people aged ≥ 65 years were analysed [mean (SD) age 72.5 (11.3) years; 45.2% males]. The overall prevalence of self-reported fall-related injury and visual symptoms (suggesting cataract) were 4.9% and 29.4%, respectively. There was a positive association between self-reported visual symptoms (suggesting cataract) and fall-related injury (i.e., OR > 1) in all five countries but statistical significance was reached in three: China (OR = 1.60; 95% CI = 1.08–2.35), India (OR = 1.96; 95% CI = 1.15–3.35), and Russia (OR = 3.58; 95% CI = 2.06–6.24). The pooled OR including all five countries based on a meta-analysis was OR = 1.88 (95% CI = 1.32–2.68).</p> <p>Conclusions</p> <p>Self-reported visual symptoms (suggesting cataract) were associated with higher odds for self-reported injurious falls among older adults in LMICs. Expanding availability of cataract surgery in LMICs may also have the additional benefit of reducing falls among older people.</p>
