Visual impairment is diagnosed by a doctor according to guidelines. Data were analyzed using multiple correspondence and logistic regression analysis. This research represents an important step towards the development of empirically based practical suggestions for decision-makers and health professionals that support visually impaired middle-aged and elderly people to participate in physical exercise and weight management when needed.Results: Of the 1335 middle-aged and elderly adults (mean age ± SD, 63.56 ± 7.74 years; 45.6% male) with VI, a total of 154 (11.5%) developed CHD. In all people with VI, age (OR 1.47; 95% CI 1.16– 2.02), hypertension (OR 2.14; 95% CI 1.46– 3.14), diabetes (OR 3.79; 95% CI 2.29– 6.27), blindness (OR 1.68; 95% CI 1.16– 2.43), moderate activity (OR 0.86; 95% CI 0.69– 0.98), and HR < 60 beats/min (OR 1.43; 95% CI 1.08– 2.48) are significantly related to CHD. Statistical analysis based on age grouping indicated that fasting plasma glucose, hypertension, diabetes, blindness, heart rate (< 60 beats/min), and moderate activity were shown to have a strong association with development of CHD in age group < 65 years (p < 0.05).Conclusion: Compared with historical data, poorer vision degree, resting heart rate below 60 beats a minute and low physical activity level are emerging as new and increasing threats to CHD in middle-aged and elderly VI population. Interventions to enhance physical functioning and risk screening may be effective in the prevention of CHD in VI population.Keywords: coronary heart disease, vision disability, prevalence, risk factors, physical activity
