Effect of Nutrition Education Groups in the Treatment of Patients with Type 2 Diabetes

Официальное название

Effect of Nutritional Education Groups Added in the Usual Care of Outpatients with Type 2 Diabetes: a Randomized Clinical Trial

Обзор

Every year there is an increase in people with diabetes all over the world. Because it is a disease associated with several comorbidities and is increasing, there is a need for more effective treatments. Lifestyle changes combined with medication are the best strategies for the treatment and reduction of comorbidities. Therefore, the present study posits the hypothesis that the integration of nutritional education groups into standard treatment, within a nutrition-specialized outpatient clinic, may yield additional enhancements in health parameters among patients diagnosed with type 2 diabetes. The driving force behind this research lies in the pursuit of more effective strategies to enhance glycemic control, diminish the risk of complications, and elevate the overall quality of life for these patients. Our motivation stems from a commitment to base our interventions on scientific evidence and strive towards meaningful improvements in diabetes management outcomes. A randomized clinical trial will be conducted with adult patients with a previous diagnosis of type 2 diabetes. Patients will be divided into two groups (intervention: nutritional education added the usual care; and control: usual care). The outcomes analyzed will be: glycemic control, lipid profile, body mass and dynapenia obesity, blood pressure values, eating behavior, diabetes complications and adherence to recommendations.

Подробное описание

The estimate of patients with diabetes increases every year and for their treatment, a change in lifestyle is essential, so there is a need to seek strategies that increase patient adherence in the long term. Therefore, the present study posits the hypothesis that the integration of nutritional education groups into standard treatment, within a nutrition-specialized outpatient clinic, may yield additional enhancements in health parameters among patients diagnosed with type 2 diabetes. The driving force behind this research lies in the pursuit of more effective strategies to enhance glycemic control, diminish the risk of complications, and elevate the overall quality of life for these patients. Our motivation stems from a commitment to base our interventions on scientific evidence and strive towards meaningful improvements in diabetes management outcomes.

An open randomized clinical trial will be performed. Patients = patients with type 2 DM; Intervention = food (nutritional) education based on operative groups added the usual care; Control = usual care; Outcome/Outcomes = glycemic control, lipid profile, body mass and dynapenia obesity, blood pressure values, eating behavior, diabetes complications and adherence to recommendations. In order to detect a mean difference of 0.59 in HbA1c between patients randomized to the intervention (patient-centered group) and those in the control group (traditional education intervention), with a standard deviation of 1.39%, a type I error of 5%, and a type II error of 20%, a total of 88 patients in each group were deemed necessary (1:1 ratio at randomization, n= 176). Considering a dropout rate of 30% over the long term (12 months), it will be essential to include a total of 252 participants.
