Intervention / Treatment
Detailed Description
This is a multicentric randomized clinical study coordinated by the Hospital Beneficência Portuguesa in São Paulo-Brazil and made possible by PROADI-SUS (SUS Institutional Development Support Program).
The study's objective is the Brazilian Diabetes Prevention Program development based on guidance for changing lifestyle promoted by the American Diabetes Prevention Program, using materials already developed by the Brazilian Ministry of Health and contextualizing it to the Brazilian Public Health System (SUS).
The program will not include a multidisciplinary orientation, but the prescription will have a multi-professional vision. The objective is to bring the multi-team together to discuss different aspects of the same intervention, such as accessibility, motivation, contexts, and needs, so that the program, to be guided by the nutritionist, can also be recognized and supported by the other teammates.
Once the program is defined, the research teams from the collaborating centers will be trained and qualified. 220 individuals with pre-diabetes will be included in the study and followed for 3 months. Outcomes are diet quality and time of physical activity. Health care professionals' perceptions regarding its incorporation into clinical practice will also be evaluated.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Brazilian Diabetes Prevention Program Group
The program will be based on the American Diabetes Prevention Program (DPP), whose published results are used as a reference for prediabetic care patients in the Brazilian Diabetes Guideline.
In order to reach the weight loss goal estimated at 0.5 to 1 Kg per week and 150 minutes of moderate physical activity per week, the program will offer individual and group visits, qualitative guidelines for improving diet, lifestyle and self-care.
|
A Program structured in 7 visits (in group and individual) to guide the improvement of diet quality, self-care, and practice of physical activity
|
Active Comparator: Diet Group
Diet prescription for weight loss
|
Hypocaloric diet prescription
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Quality of diet
Time Frame: 3 months
|
to compare mean score of Brazilian Cardioprotective Nutritional Program dietary index (BALANCE DI) between groups.
the index has a score from 0 to 40, with a high score indicating adherence to a healthy diet (BALANCE).
|
3 months
|
Minutes of Moderate Physical activity
Time Frame: 3 months
|
to compare mean time in minutes of practice of moderate/vigorous physical activity over a week between groups
|
3 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Moderate or vigorous physical activity (according to IPAQ-short)
Time Frame: 3 months
|
to compare proportion of individuals who perform at the end of the follow-up moderate or vigorous physical activity
|
3 months
|
Cardioprotective diet adherence
Time Frame: 3 months
|
to compare adherence to a healthy and cardioprotective diet based on the Cardiovascular Health Diet Index (CHDI) between groups.
The CHDI had 11 components and a total score ranging from 0 to 110 points.
the higher the score, the greater adherence to a healthy and cardioprotective diet
|
3 months
|
weight
Time Frame: 3 months
|
to compare mean weight (kg) between groups
|
3 months
|
HbA1c
Time Frame: 3 months
|
to compare mean HbA1c(%) between groups
|
3 months
|
Glycemia
Time Frame: 3 months
|
to compare mean Glycemia (mg/dL) between groups
|
3 months
|
Implementation Barriers and Facilitators
Time Frame: 3 months
|
Identification of Barriers and Facilitators of Program implementation from a qualitative analysis approach.
This is not a score on a scale.
For the qualitative data, thematic content analysis will be performed with the transcription of the focus groups.
This analysis will serve to describe and understand perceptions, interpretations and beliefs from the perspective of managers and professionals about the intervention.
The thematic nuclei will be defined a posteriori according to the references of models and implementation frameworks also used for the realization of the focus groups
|

|
Global DNA Methylation
Time Frame: Baseline and 3 months
|
participants' global DNA methylation using the RRBS method (Reduced Representation Bisulfite Sequencing).
