In this study, we aimed to determine the prevalence of visually significant cataract and associated factors among older people attending community ophthalmic services in the central Gondar Zone, Northwest Ethiopia.
We conducted a community outreach-based cross-sectional study among adults aged ≥40 years in the central Gondar Zone from 30 May to 15 June 2021. We used systematic random sampling to select study participants. Interviewer-administered questionnaires and ocular examinations were performed and the data recorded. We applied binary logistic regression to identify factors associated with visually significant cataract.
A total of 821 participants were included, with median age 57 years. The prevalence of visually significant cataract was 29.1% (95% CI: 26.1-32.0). Age ≥80 years (adjusted odds ratio [AOR] = 16.9; 95% CI: 7.5-38.4), rural residence (AOR = 1.7; 95% CI: 1.02-2.7), unmarried status (AOR = 1.9; 95% CI: 1.2-3.2), illiteracy (AOR = 2.9; 95% CI: 1.4-6.1), unemployed status (AOR = 1.7; 95% CI: 1.1-2.7), and sunlight exposure ≥5 hours per day (AOR = 1.6; 95% CI: 1.04-2.4) were significantly associated with visually significant cataract.
In this study, visually significant cataract was found to be high, which requires immediate public health intervention.
本研究旨在确定在埃塞俄比亚西北部贡德尔地区中心的社区眼科服务中，老年人中视力明显白内障的患病率及其相关因素。
我们在 2021 年 5 月 30 日至 6 月 15 日期间在贡德尔地区中心进行了一项基于社区外展的横断面研究，研究对象为年龄≥40 岁的成年人。我们采用系统随机抽样选择研究参与者。通过访谈员管理的问卷和眼部检查进行研究，并记录数据。我们应用二元逻辑回归来确定与视力明显白内障相关的因素。
共有 821 名参与者被纳入研究，中位年龄为 57 岁。视力明显白内障的患病率为 29.1%（95%置信区间：26.1-32.0）。年龄≥80 岁（调整后的优势比 [AOR] = 16.9；95%置信区间：7.5-38.4）、农村居住（AOR = 1.7；95%置信区间：1.02-2.7）、未婚状态（AOR = 1.9；95%置信区间：1.2-3.2）、文盲（AOR = 2.9；95%置信区间：1.4-6.1）、失业状态（AOR = 1.7；95%置信区间：1.1-2.7）和每天暴露在阳光下≥5 小时（AOR = 1.6；95%置信区间：1.04-2.4）与视力明显白内障显著相关。
在这项研究中，视力明显白内障的患病率较高，需要立即采取公共卫生干预措施。
