Influencing factors of vision-threatening disease among patients with diabetes in the central region of Saudi Arabia: A case-control study.

Abstract

Diabetic retinopathy is called as vision threatening disease. It affects retina very severely. DR is a common public health problem in Worldwide. Our main objective was to identify significant risk factors for diabetic retinopathy among diabetes mellitus patients. The present retrospective Case-Control study was conducted with 404 DM patients' records were collected from King Abdulaziz Medical City, Riyadh, Saudi Arabia. Data were presented as descriptive statistics, multivariate logistic regression, association between variables was using odds ratio and 95% confidence interval. Among 404 diabetes patients, 192 (47.5%) were Cases and 212 (52.5%) Controls. In multivariate regression analysis showed that male gender also had a higher likelihood in the development of DR, OR: 1. 68 [95% CI: (1.04 - 2.71); p<0.05]. Patients with poor glycaemic control, OR: 4. 86 [95% CI: (2.21-10.66); p<0.001]. Similarly, HbA1C, Low LDL was prominent risk factor in the progression of DR except age, hypocholesterolaemia, nephropathy wasn't significant. From our study findings, male gender, tobacco habit, poor glycaemic control, and Low HDL were appeared independently associated with the development of vision-threatening disease. By regular check-up, reducing risk factors or retain their stages in the same stage or to prolong the DR incidents among DM patients.
