This study aimed to investigate whether dietary pattern associate with hypertension and which dietary pattern have protective role in development of hypertension.1787 healthy subjects (718 men and 1069 women) Participants in Tehran Lipid and Glucose Study who had normal blood pressure were enrolled in study. Weight and height of participants was measured and body mass index (BMI) was calculated. Blood pressure was taken on the right arm. Physical activity levels were assessed using Krista’s physical activity questionnaire. Dietary data was collected by validated semi-quantitative FFQ. Using factor analysis we extract 3 dietary food patterns: healthy, western and mix. The healthy dietary pattern was negatively associated with elevated systolic blood pressure in model 2 and 3 (odds ratio: 0.74 (0.56-0.98) and 0.74 (0.56-0.97) respectively, P =0.03 for both). Neither the healthy dietary pattern in crude model nor western dietary pattern in crude model and after adjustment for covariates, were associated with incidence of hypertension. We found that adherence to healthy dietary pattern cause 26 % reduction in hypertension incidence risk. Since the hypertension consider as independent risk factor for heart and kidney diseases, Strategies to reduce the incidence of hypertension may indirectly reduce the burden of these diseases.
