Risk factors for self-reported cataract symptoms, diagnosis, and surgery uptake among older adults in India: Findings from the WHO SAGE data

Abstract

ABSTRACT Visual impairments have a substantial impact on the well-being of older people, but their impact among older adults in low- and middle-income countries is under-researched. We examined risk factors for self-reported cataract symptoms, diagnosis, and surgery uptake in India. Cross-sectional data from the nationally representative WHO SAGE data (2007–2008) for India were analysed. We focused on a sub-sample of 6558 adults aged 50+, applying descriptive statistics and logistic regression. Nearly 1-in-5 respondents self-reported diagnosed cataracts, more than three-fifths (62%; n = 3879) reported cataract symptoms, and over half (51.8%) underwent surgery. Increasing age, self-reported diabetes, arthritis, low visual acuity, and moderate or severe vision problems were factors associated with self-reported diagnosed cataracts. Odds of cataract symptoms were higher with increasing age and among those with self-reported arthritis, depressive symptoms, low visual acuity, and with moderate or severe vision problems. Odds of cataract surgery were also higher with increasing age, self-reported diabetes, depressive symptoms, and among those with low visual acuity. A public health approach of behavioural modification, well-structured national outreach eye care services, and inclusion of local basic eye care services are recommended.
