The study aimed to assess the proportion of visual impairment and associated factors among diabetic patients at Debre Berhan Referral Hospital (DBRH).
A hospital-based cross-sectional study was carried out from April 27 to May 19, 2017. All adult diabetic patients attending DBRH during the study period were included in the study. A pretested, structured questionnaire and clinical examinations were used for data collection. The collected data were entered into Epi Info 7 and exported to the Statistical Package for Social Sciences version 20 for analysis. The descriptive analysis was summarized by frequency, percent, and summary statistics. Association between visual impairment and independent variables was determined via bivariable and multivariable binary logistic regressions. < 0.05 was considered statistically significant. Adjusted odds ratio (AOR) and 95% confidence interval (CI) were used to determine the strength of association. Hosmer and Lemeshow goodness of fit was used to check for model fitness.
A total of 388 study subjects with a 92% response rate took part in the study. The prevalence of visual impairment was 29.38% (95% CI: 24.83%-33.93%). Age >56 years (AOR = 5.24, 95% CI: 1.37-20.04), physical inactivity (AOR = 2.34, 95% CI: 1.33-4.14), presence of visual symptoms (AOR = 4.48, 95% CI: 2.35-8.57), lower body mass index (AOR = 6.23, 95% CI: 1.87-20.68), and diabetic retinopathy (AOR = 5.12, 95% CI: 1.91-13.70) had a statistically significant association with visual impairment.
A high proportion of diabetic patients had visual impairment. Independent variables older age, physical inactivity, presence of visual symptoms, lower body mass index, and diabetic retinopathy had a positive statistically significant association with visual impairment.
本研究旨在评估德布雷伯汉转诊医院（DBRH）糖尿病患者的视力障碍比例及其相关因素。
这是一项 2017 年 4 月 27 日至 5 月 19 日进行的基于医院的横断面研究。研究期间，所有在 DBRH 就诊的成年糖尿病患者均被纳入研究。使用经过预测试的结构化问卷和临床检查进行数据收集。收集的数据被输入 Epi Info 7 并导出到统计软件包社会科学版 20 进行分析。描述性分析通过频率、百分比和汇总统计数据进行总结。通过双变量和多变量二元逻辑回归确定视力障碍与独立变量之间的关联。<0.05 被认为具有统计学意义。调整后的优势比（AOR）和 95%置信区间（CI）用于确定关联的强度。Hosmer 和 Lemeshow 拟合优度用于检查模型拟合情况。
共有 388 名研究对象参与了研究，应答率为 92%。视力障碍的患病率为 29.38%（95%CI：24.83%-33.93%）。年龄>56 岁（AOR=5.24，95%CI：1.37-20.04）、身体不活动（AOR=2.34，95%CI：1.33-4.14）、存在视觉症状（AOR=4.48，95%CI：2.35-8.57）、较低的身体质量指数（AOR=6.23，95%CI：1.87-20.68）和糖尿病视网膜病变（AOR=5.12，95%CI：1.91-13.70）与视力障碍有统计学显著关联。
相当一部分糖尿病患者存在视力障碍。年龄较大、身体不活动、存在视觉症状、较低的身体质量指数和糖尿病视网膜病变等独立变量与视力障碍呈正相关且具有统计学意义。
