Background: The study aimed to estimate the prevalence and associated factors of health literacy of undiagnosed type 2 diabetes (T2D) among adults in Sudan. Methods: Cross-sectional data were analyzed from 6,967 persons (18-69 years, with a mean age of 38.0 years) who participated in the Sudan STEPS survey in 2016, who had complete fasting blood glucose measurement. Results: The prevalence of health literacy of undiagnosed T2D was 3.4% (47.9% of total T2D), diagnosed T2D 3.7%, and total T2D 7.1%. In the adjusted multinomial logistic regression analysis, older age (50-69 years) (ARRR: 2.05, 95% CI: 1.16-3.63), obesity (ARRR: 2.03, 95% CI: 1.27-3.27), hypertension (ARRR: 1.94, 95% CI: 1.38-2.72), and elevated total cholesterol (ARRR: 1.59, 95% CI: 1.10-2.30) were positively associated and high physical activity (ARRR: 0.50, 95% CI: 0.33-0.77) was negatively associated with undiagnosed T2D versus no T2D. Older age (50-69 years) (ARRR: 12.98, 95% CI: 7.31-23.02), urban residence (ARRR: 1.63, 95% CI: 1.12-2.37), received health care advice (ARRR: 2.03, 95% CI: 1.44-2.87), ever cholesterol screening (ARRR: 2.20, 95% CI: 1.41-3.42), higher education (ARRR: 1.87, 95% CI: 1.21-2.87), obesity (ARRR: 2.19, 95% CI: 1.49-3.22), and elevated total cholesterol (ARRR: 1.71, 95% CI: 1.16-2.53) were positively associated with diagnosed T2D versus no T2D. In adjusted logistic regression analysis, older age (50-69 years) (AOR: 0.18, 95% CI: 0.09-0.33), and health care advice (AOR: 0.32, 95% CI: 0.19-0.56) were negatively associated with undiagnosed T2D versus diagnosed T2D. Conclusion: A significant proportion of adults in Sudan had low health literacy of undiagnosed T2D, and several associated factors were identified which can help in guiding interventions.
