Abstract

Whether the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-7) guidelines can be applied to the Asian population remains unclear. We aim to test the hypothesis that adherence to the JNC-7 guidelines is associated with hypertension in a representative sample of the Korean population in the fourth Korea National Health and Nutrition Examination Survey. Participants completed a non-quantitative food frequency questionnaire and 24-hour diet recall through interviews. Blood pressure, height, and weight were directly measured, and questions about physical activity and other lifestyle factors were administered. A total of 500 hypertensive and 4567 normotensive participants were identified. We estimated the odds ratio and 95% confidence intervals using a multivariate logistic regression. The following components of the JNC-7 guidelines were considered: dietary approaches to stop a hypertension style diet, moderate consumption of alcohol, adequate physical activity, and a normal body mass index. Those individuals who fell in the low-risk category for all 4 lifestyle components had an odds ratio of 0.48 (95% confidence interval, 0.30-0.78) compared with the remainder of the participants. In conclusion, we found an inverse association between adherence to the JNC-7 guidelines and hypertension prevalence among Korean adults, suggesting the importance of lifestyle modification for the prevention and management of hypertension.
