PERFIL DIETÉTICO ANTIOXIDANTE DE MULHERES CLIMATÉRICAS HIPERTENSAS DO SUL DO BRASIL.

Introduction: Oxidative stress is involved in the pathophysiology of systemic arterial hypertension (HAS) and the role of antioxidants in this context still needs to be better understood. Objective: To evaluate the prevalence of hypertension and the relationship with polyphenol intake and total dietary antioxidant capacity (DTAC) in climacteric women from Serra Gaúcha-RS, Brazil. Materials and methods: 41 women participated in the study (CEP 2,420,632; 12/07/2017) and they were subjected to measurements of weight, height, waist circumference, and blood pressure. Different questionnaires were applied to obtain sociodemographic and health information, in addition to the 24-hour Food Recall. Comparisons between the hypertensive and non-hypertensive groups were made using Student's t-test or chi-square. Results: The prevalence of HAS in the population was 29,27 % (IC95% 14,73; 43,81) and hypertensive women had a BMI statistically higher than nonhypertensive women (p=0.047). Although without a statistical difference, it was observed that the hypertensive group had decreased DTAC and total polyphenol intake (9 and 11% reduction, respectively). The mineral magnesium had its intake significantly reduced (30%; p=0.006) by hypertensive women. This group also had an intake below the recommended for vitamins A and E. Among the foods and beverages that contributed to increasing the participants' DTAC, coffee ranked first in both groups. Conclusion: These data demonstrate the importance of monitoring the consumption of antioxidants to prevent and/or control hypertension and diseases related to heart health in climacteric women.
