PS-C23-8: COFFEE INTAKE AND RISK OF HYPERTENSION IN KOREAN ADULTS: RESULTS FROM KNHANES 2012–2016

Abstract

Introduction: Coffee is the most popular and widely consumed drink in South Korea. Coffee consumption seems to have both benefits and risk with respect to hypertension. But, results from studies evaluating effect of frequency of coffee consumption on risk of hypertension are mixed and inconsistent. Hence, this study investigated the effect of frequency of coffee consumption on risk of hypertension in Korean adults. Methods: Data from Korean National Health and Nutrition Examination Survey (KNHANES 2012–2016) was obtained and 12133 eligible participants were selected. The consumption of coffee was obtained at baseline using a food frequency questionnaire (FFQ). Subsequently coffee intake was categorized into three categories (cups/day): < 1, 1–3, and > 3 cups/day. Hypertension status was defined as a systolic blood pressure > 140 mmHg or a diastolic blood pressure > 90 mmHg, use of antihypertensive drug treatment, or both. Multivariable logistic regression analysis was used to examine the effect of coffee consumption on risk of hypertension. Results: Fifty-five percent participants drank coffee 1–3 cups coffee/day. A total of 2359 participants had hypertension. In all participants more than 3 cups of coffee intake in a day was significantly reduced the risk of hypertension with Odds Ratio (OR) 0.76 (95%C.I. 0.65,0.89). Participants in middle age (40–59 years) group OR 0.76 (95% C.I. 0.63,0.93), normal range BMI OR 0.65 (95% C.I. 0.52,0.80), not diabetic OR 0.79 (95% C.I. 0.64,0.98), normal cholesterol OR 0.76 (95% C.I. 0.63,0.94) had protective effect of coffee consumption against risk of hypertension. Conclusion: The beneficial effect of > 3 cups of coffee intake in a day were seen in middle age, normal BMI, not diabetic and normal cholesterol participants compared to consumption of < 1 cup/day.
