Evaluation on the Effectiveness of Nutritional Counseling on an Adapted DASH Diet in Patients After Stroke: a Randomized Clinical Trial

Stroke is the leading cause of disability worldwide and the leading cause of death in Brazil. It is estimated that about 18 million people will have a stroke in 2015 and approximately one third of these resulting in death. The factors most important modifiable risk for stroke include high blood pressure (hypertension), diabetes, smoking, dyslipidemia, sedentary lifestyle and obesity. Acting on these risk factors can be reduced by 88% the risk of another stroke. Healthy eating is among the changes in lifestyle that are recommended for prevention and treatment of one of the main risk factors for stroke. Studies show that the adoption of the DASH diet can significantly reduce blood pressure and the result is even more significant in hypertensive patients, making this diet a new alternative in the prevention and treatment of hypertension and consequently stroke. Compliance therapy is a determining factor for success in the treatment of chronic diseases. Adherence to long-term treatment in developed countries is around 50% and in developing countries the rates are even lower. The aim of this study is to evaluate the effectiveness of nutritional counseling in an adapted DASH style diet on body weight, glycemic control, blood pressure values and improved lipid profile compared to the usual diet without nutritional counseling in patients with stroke within the last 3 months. The hypothesis is that nutritional counseling with an adapted DASH style diet reduces cardiovascular risk factors compared with the usual diet without nutritional counseling in patients with stroke within 3 months. The stroke patients will be selected in the hospitalization or in the outpatient clinic of Hospital de Clínicas de Porto Alegre in a period up to 3 months after ischemic stroke. The patients will be randomized to one of the 2 groups. In the first visit they will be submitted to a social class and international physical activity questionnaire and they will be submitted to a food frequency questionnaire, measures of weight, height, waist circumference, hip and neck, blood pressure and cholesterol and glucose measurements at the baseline, 30 days and 3, 6, 9 and 12 months. The main endpoints will be the change in the body weight, blood glucose, blood pressure values and lipid profile.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will be followed by a evaluation of other endpoints: new stroke, myocardial infarction or cardiovascular death.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Nutritional counseling
It was composed by patients who received specific written orientation to follow the DASH diet recommendations. Calories were calculated with the goal of maintaining body weight and divided into 3 main meals and two to three snacks.
Other: Nutritional Counseling
2 groups: 1 with nutritional counseling and other with usual diet without nutritional counseling
Other Names:
  • nutrition
  • adherence
No Intervention: Usual diet
It was composed by patients who were stimulated to follow the general orientations of the neurologist or keep their food intake habits

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline arterial blood pressure and 6 months
Time Frame: 30 days and 3, 6, 9 and 12 months
The patients will be randomized to one of the 2 groups (with nutritional counseling and no intervention - habitual diet). The main endpoint will be the change in the blood pressure values and adherence to treatment measured in 30 days and 3, 6, 9 and 12 months.
30 days and 3, 6, 9 and 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in lipids from baseline
Time Frame: 30 days, 3, 6, 9 and 12 months
The patients will be randomized to one of the 2 groups (with nutritional counseling and no intervention - habitual diet). The secundary endpoint will be the change in the lipid profile and adherence to treatment measured in 30 days and 3, 6, 9 and 12 months.
30 days, 3, 6, 9 and 12 months
Change in the body weight
Time Frame: 30 days and 3, 6, 9 and 12 months
