Among these, 167 (1.22%) reported incident cataract surgery. Those receiving surgery were significantly older (66.2\u00b18.79 vs 58.3\u00b19.18, p\u22640.001) and more likely to report: illiteracy (44.9% vs 27.1%, p&lt;0.001), poor baseline distance vision (49.7% vs 20.0%, p\u22640.001), poor baseline near vision (37.1% vs 21.8%, p\u22640.001), baseline visual impairment (15.6% vs 5.5%, p\u22640.001), diabetes (12.0% vs 7.42%, p\u22640.05) and higher baseline depression scores (9.7 vs 8.4 on a scale of 0\u201330, p\u22640.05). In linear regression models, older age, worse distance vision, hypertension or diabetes, illiteracy and lower depression score were significantly associated with undergoing surgery. Results were similar in models including only persons aged \u226560 years, except that urban residence was also associated with surgery. When only those aged \u226560 years with poor vision were included, results were again the same, except that higher household expenditure was also associated with surgery.<\/jats:p>\n
