Abstract:  Objective To investigate the prevelence and risk factors of hypertensive retinopathy in Zhangjiakou City, Hebei province. Design Cross-sectional study. Participants Residents in 19 counties of Zhangjiakou city from May 2021 to December 2022. Methods The residents were screened for hypertension and hypertensive retinopathy. Blood pressure measurements, eye examinations and venous laboratory tests were performed on all the subjects. Age, gender, course of disease, body mass index and complications of the patients were collected by questionnaire. The prevalence of hypertensive retinopathy among residents in Zhangjiakou City was analyzed and the risk factors affecting the prevalence were analyzed. Main Outcome Measures Prevalence, the risk factors. Result A total of 1320 hypertension patients were detected in 8056 residents, and the prevalence rate of hypertension was 16.39%. 212 of the 1320 hypertensive patients were found to have retinopathy, the prevalence was 13.06% in hypertensive patients and 2.63% in all the examined residents. There was no difference between the proportion of male and female patients with hypertensive retinopathy, and the proportion of patients aged ≥60 years old was higher than that of patients aged < 60 years old (P<0.05). The disease course, systolic blood pressure, diastolic blood pressure, diabetes and smoking history in the patient group were higher than those in the control group (P<0.05). Regression results showed that long course of disease (OR=1.747), high systolic blood pressure (OR=2.340), high diastolic blood pressure (OR=1.424), diabetes history (OR=13.481) were risk factors for the occurrence of hypertensive retinopathy (all P<0.05). Conclusion The prevalence of hypertensive retinopathy in 19 counties and districts of Zhangjiakou City was about 13%, and the prevalence was high among residents aged ≥60 years. The risk factors were long course of disease, high systolic blood pressure, high diastolic blood pressure, and diabetes history. (Ophthalmol CHN, 2024, 33: 57-60)
