Relationship between Participation in Health Checkups and the Prevalence of Dyslipidemia among Korean Adults Aged 60 Years and Older

Background: With the rapid aging of the population, the early detection and prevention of chronic diseases have become increasingly important.Health checkups are considered a key strategy for identifying asymptomatic conditions such as dyslipidemia.Methods: Using data from the 2023 Korea National Health and Nutrition Examination Survey, we conducted a cross-sectional study of 2,257 adults aged 60 years and older.Participants were categorized into regular and irregular health checkup groups.Multivariable logistic regression was used to assess the association between health checkup participation and dyslipidemia.Results: The prevalence of dyslipidemia was significantly higher in the regular checkup group (odds ratio, 1.87; 95% confidence interval, 1.24-2.87).In contrast, hypertension and diabetes were more prevalent in the irregular checkup group.Age was negatively associated with dyslipidemia, whereas male sex, obesity, diabetes, and hypertension were positively associated with dyslipidemia.Conclusion: Dyslipidemia was more frequently identified among individuals who underwent regular health checkups, likely reflecting increased detection of asymptomatic disease through blood testing rather than a causal relationship.These findings underscore the importance of regular health checkups for the detection of chronic conditions in older adults.
