Brief Summary

Metabolic syndrome is a multifactorial inflammatory condition that is very prevalent in overweight women with type 2 diabetes. However, there seems to be great benefit in changing lifestyle and dietary patterns in the treatment of this condition. Currently, few studies have shown the effect of a Dietary Approach to Stop Hypertension (DASH) diet in postmenopausal women with metabolic syndrome and the influence of genetic polymorphisms of the fat mass and obesity-associated protein (FTO) and beta-2 adrenergic receptor (ADRB2) genes on inflammatory markers and improvement of laboratory indicators in these patients. This study aims to analyze the interaction of polymorphisms in the ADRB2 and FTO genes and the DASH diet on anthropometric indicators and laboratory tests in patients with metabolic syndrome in the city of Rio de Janeiro. For this purpose, laboratory tests and anthropometric data will be collected in a prospective study with women aged between 40 and 60 years.

Outcome Measures

Primary Outcomes (27)

  • Systolic and Diastolic blood pressure in mmHg

    After the subject has rested for five minutes in a sitting position, blood pressure measurements will be taken using an Omron IntelliSense® Blood Pressure Monitor and an arm cuff suitable for the body size. Three readings will be taken at five-minute intervals, and the average of the three measurements will be used.

Study Arms (1)

Group 1

EXPERIMENTAL

30 menopausal women aged between 40 and 60 years who are obese (BMI \> 30) and diagnosed with metabolic syndrome. Volunteers will have in-person and online consultations with a nutritionist every 15 days for 3 months to assess their previous habitual food intake and their nutritional adherence to DASH Diet.

Other: DASH diet

Interventions

Prospective, single-arm, unblinded clinical trial lasting 90 days. The study population will consist of menopausal women aged between 40 and 60 years who are obese (BMI \> 30) and diagnosed with metabolic syndrome. Volunteers will have an in-person consultation with a nutritionist at t0 to assess their previous habitual food intake and will receive a DASH diet. To minimize losses during the study, in-person consultations with a nutritionist will be held at t0, t30, t60, t90 and online consultations (teleconsultation) at t15, t45 and t75 to answer a questionnaire to assess nutritional adherence that will be applied by the nutritionist. Saliva samples will be collected for genetic panel analysis only at t90. Serum samples for analysis of lipid profile, blood glucose, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), follicle stimulating hormone (FSH), C-reactive protein (CRP) and tumor necrosis factor (TNF) and profile of medications used will be collected at t0 and t90.
