Sex differences in factors associated with prediabetes in Korean adults

Identifying the factors associated with prediabetes is necessary for the early detection and management of high-risk individuals with prediabetes. The purpose of this study was to identify the factors associated with prediabetes according to sex in Korean adults. Using the Korean National Health and Nutrition Examination Survey from 2015 to 2019, a total of 13,595 adults (5,565 males and 8,030 females) aged ≥20 years were included in the data analysis. Logistic regression analysis was performed to identify the factors associated with prediabetes according to sex in Korean adults. In both males and females, age and a family history of type 2 diabetes were associated with prediabetes. In males, current and past smoking habits were associated with increased prediabetes. In addition, low-intensity physical activity and prolonged sedentary behavior were associated with a higher prevalence of prediabetes. Females with a lower education level (less than middle school graduation) showed a higher risk of prediabetes. Sex-specific prevention strategies for prediabetes should be developed. In addition, older individuals and those with a family history of type 2 diabetes should be screened for prediabetes.
