About this study

Official title: Effectiveness of Nutritional Intervention Alone or Associated With Other Non-pharmacological Interventions in Controlling Hypertension and Reducing Cardiovascular Risk - Randomized Clinical Trial

The purpose of this study is to evaluate the effectiveness of diet change and other non-pharmacological treatments which includes physical activity and integrative therapies oriented to reduce the blood pressure in hypertensive patients.

Read the detailed description

Despite advances in the pharmaceutical industry, blood pressure control remains the biggest challenge in the treatment of hypertension in Brazil and worldwide. In this context, besides the availability and use of antihypertensive drugs, the best therapeutic approach should start with the stratification of cardiovascular risk, and contextualized modification of life habits. In this view, the present study aims to evaluate the effectiveness of diet change and other non-pharmacological treatments oriented to reduce the blood pressure in adults diagnosed with prehypertension, hypertension, and resistant hypertension. Therefore, it includes the analysis of these 3 groups: i. pre-hypertension (to evaluate strategies adopted as primary prevention); ii. hypertension in general (to assess blood pressure control and reduce cardiovascular risk reduction), and iii. resistant hypertension (individuals using 3 or more drugs without blood pressure control who have more endothelial dysfunction and target organ damage to assess secondary and tertiary prevention with possible blood pressure control, reduction in the number of drugs in use and subclinical lesions regression). Non-pharmacological approach includes adoption of healthy lifestyles, weight loss, reduced sodium intake, regular physical activity, and integrative practices capable of maintaining biopsychosocial balance. Since those interventions seems to be the best way to reach blood pressure control, we intend to use individual interventions and group actions to increase the population's adherence contributing effectively to public policies within primary care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DIET CHANGEBehavioural

    Also called Nutritional intervention

    Nutritional supervision will be carried out individually based on the Food Guide for the Brazilian Population, ensuring an accessible, hygienic and contextualized diet according to the subject's culture and physiology. The protocol includes an initial assessment to define the meal plan and individual reassessments every four weeks. In the first evaluation participants will receive an eating plan with a 20% reduction in the total calories consumed or even the equivalent of their daily energy needs with a distribution of macronutrients comprised of 65% carbohydrate, 15% protein and 20% fat. The intention is to promote a reduction in weekly consumption by about 2000 kilocalories (Kcal). The prescription and diet control plan will include and be conducted by a team coordinated by a clinical nutritionist.

  • PHYSICAL ACTIVITYBehavioural

    Also called Aerobic training and mobility exercises

    The physical activity program will consist of daily walking sessions performed outdoors and on a flat surface suitable for hiking. Each session will last 70 minutes and will be performed between 55% -60% of the maximum oxygen consumption (VO2), six times a week, for 24 weeks, with alternate on-site supervision on odd days and remote monitoring on even days. On-site supervision will be carried out by a team coordinated by a Physical Education teacher and implemented at two times in the morning and another two in the afternoon with meeting points previously defined. At the end of each supervised walking session, 20 minutes of exercise will be performed using the equipment available at the Senior Citizens Academy set up in public squares in the region so that the total expenditure of calories spent weekly with physical activities reach about 2000 kilocalories.

  • INTEGRATIVE PRACTICESOther

    Also called Holistic Health Integrative practices: mind-fullness meditation and auriculotherapy

    The health integrative practices will includes Mind-Fullness, auriculotherapy and laying on of hands. A suitably qualified professional, using it use a practical manual so that the practice became uniform among the subjects, will apply the practice of Mind-Fullness in weekly 1-hour sessions to individuals. The practice of auriculotherapy will be applied to individuals by a professional qualified to perform the technique, which consists in the selection of auricular points according to the health problems presented and the therapeutic objectives that are to be achieved, followed by the insertion of the mustard seed at specific points in the ear over a six-month period. The laying on of hands will be carried out by properly trained individuals.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Blood pressure

    Indicators: Office blood pressure and Home Blood Pressure Monitoring (HBPM) after 6 months of non-pharmacological intervention Goals: Nutritional strategy: reduction of 1 mmHg by reducing each kg of body weight and reducing salt intake reaching <1.5 g / day with a reduction of 2 to 3 mmHg.

    Physical activity: reduction of 6 to 8 mmHg in office systolic blood pressure and 4 to 6 mmHg in HBPM with good adherence to moderate aerobic exercise Integrative practices: 4 mmHg reduction in systolic blood pressure

    Measured: 21 months

Secondary outcomes (2)
  1. Body weight

    Indicators: Body weight reduction after 6 months of non-pharmacological intervention Goals: reduction of body weight by 0.9 kg to 1.1 kg each month It is believed that the nutritional intervention and physical activity group has a higher monthly weight loss, reaching up to 2 kg / month.

    Measured: 21 months

  2. Body composition

    Indicators: the reduction in fat mass is expected in all intervention groups with an increase in lean muscle mass, especially in groups 2 and 3, which include physical activity. The goal is to achieve a lean mass of over 30% in women and 33% in men.

    Measured: 21 months

Model description
Besides the control group (n=60), three other groups with different severity of hypertension will be included in the study. To evaluate strategies adopted as primary prevention 60 pre-hypertensive patients will be recruited. To evaluate blood pressure control and cardiovascular risk reduction, other 60 hypertensives will be also invited to the study. Finally, 60 individuals with resistant hypertension will be recruited to access secondary and tertiary prevention with possible blood pressure control, reduction in the number of drugs in use and subclinical lesions regression.
