Association between excessive alcohol consumption and hypertension control in hypertensive patients

The purposes of this study were to investigate the association between excessive alcohol consumption and control of hypertension and the associations stratified by sex, age, and duration of hypertension among Korean adults who were diagnosed with hypertension under medication.

This study was cross-sectional design with a secondary data analysis using national data from the Korea National Health and Nutrition Evaluation Survey (KNHANES) collected from 2013 to 2018, including 4278 participants who were diagnosed with hypertension under medication. A multiple logistic regression analysis was conducted to evaluate the associations between excessive alcohol consumption and hypertension control while controlling for potential confounding variables.

The hypertensive patients who consumed excessive alcohol were more associated with uncontrolled hypertension (OR, 1.31; 95% CI, 1.04-1.65) than those who do not consumed excessive alcohol. Specially, Excessive consumption of alcohol in men and young adults (<65 years) and short duration of hypertension (<5 years) were significantly more associated with uncontrolled hypertension compared to their counterparts.

To improve blood pressure (BP) control in hypertensive patients, healthcare plan should be focused to modifiable risk factors and the intervention for unhealthy alcohol consumption should be part of comprehensive treatment for hypertension.
