Dietary Intake And Anthropometric Status In Hypertensive Patients Compered To Normotensive Participants In The North Of Iran

INTRODUCTION Hypertension is one of the main reasons of morbidity and mortality in the developing countries including Iran. It has been shown that hypertension is a consequence of the interaction of genetics and environment. Macronutrients and micronutrients have important roles in the regulation of blood pressure and target organ damage. OBJECTIVE We investigated dietary intake and anthropometric statusin hypertensive patients in the north of Iran,that have special dietary habit and lifestyle according to their culture and geographical situation. Methods:This study was conducted on 127 patients with newly recognized hypertension and the 120 normal participants, in the north of Iran. Anthropometric data was measured and demographic characteristics, and medical status were collected by valid questionnaires and dietary intake assessment was undertaken with 3-day food recall (two weekdays and one weekend), by trained interviewers. RESULTS Themean age of participants was 58 ± 6.7 years. The mean level of energy intake, saturated fat, vitamin D, potassium, zinc, dietary fiber, vitamin C, calcium, phosphorus, copper and magnesium was significantly lower in the hypertensive group compared to the control (p < 0.05). After adjusted for energy intake, positive association was observe between hypertension and some dietary nutrient including; Cholesterol [OR: 1.1, P: 0.001, B: 0.06], fiber [OR: 1.6, P: 0.001, B: 1.8], vitamin D [OR: 2.6, P: 0.006, B: 0.9] and zinc [OR: 1.4, P: 0.006, B: 0.3] intake. The result of logistic regression analysis showed, there was no significant association between hypertension and body weight and waist circumference. Conclusion:In our study, the mean intake of some nutrients was lower in the hypertensive individuals compared to the normotensive individual. Health training about suitable dietary habits and easier access to vitamin D supplementation in patients with hypertension are cost-effective tools to improve outcomes in Iran.
