Purpose: The purpose of this study was to identify age-specific factors that affect the management of hypertension in patients aged 19 years and older and provide a basis for developing effective management strategies. Methods: Data from the Eighth National Health and Nutrition Examination Survey (2019~2021) on 5,092 individuals with hypertension were analyzed. Factors that influenced hypertension awareness, treatment, and control were identified through a multivariate logistic regression analysis. The prevalence, awareness, treatment, and control rates of hypertension were analyzed by age group using a x2 test. Results: The prevalence, awareness, and treatment rates of hypertension increased significantly with age. Among those aged 40~49 years, comorbidity, stress levels, and regular health check-ups were important factors in controlling hypertension; among those aged 50~59 years, education and income were critical factors, while for those aged 60 years and older, spousal presence and physical activity level were crucial. Younger age groups had lower levels of hypertension control. Conclusion Factors influencing hypertension control vary with age group. A personalized hypertension management strategy that considers the characteristics of each age group is required. In all age groups, an integrated management of comorbidities is important. Younger age groups should focus on improving awareness and treatment rates.In middle-aged adults, stress management and increased health screenings are key, whereas in older adults, an increased physical activity and social support are important.
