| Summary: | Abstract We conducted a population-based, cross-sectional study in Japan to identify risk factors for retinal vascular events separately by gender. Forty years or older participants were recruited. Fundus photographs were taken, and lifestyle and health characteristics were determined through a questionnaire and physical examinations. We compared the group of those who had retinal vascular events and those who did not. A total of 1689 participants (964 men) were deemed eligible for the study and retinal vascular events were seen in 59 subjects (3.7% of the men, 3.2% of the women). Self-reported diabetes mellitus was significantly associated with the vascular events in each gender [odds ratio (OR) = 6.97, 6.19 (men, women); 95% confidence interval (CI) 3.02–15.9, 2.25–17.0; p < 0.001]. Higher systolic blood pressure (OR = 1.03; 95% CI 1.01–1.04; p = 0.006) and lower frequency of meat consumption (OR = 0.73; 95% CI 0.54–0.99; p = 0.04) were independently associated with the vascular events in men. In women, while vascular events were associated with self-reported hypertension (OR = 2.64; 95% CI 1.03–6.74; p = 0.04), no association was seen with systolic blood pressure. Women with hypertension may need extra care, not only for blood pressure.
