Clinical Trial Summary

To structure a Brazilian Diabetes Prevention Program 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) and evaluating its effectiveness in a multicentric randomized clinical trial with 220 pre-diabetic patients and a follow up of 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Quality of diet	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
Primary	Minutes of Moderate Physical activity	to compare mean time in minutes of practice of moderate/vigorous physical activity over a week between groups	3 months
Secondary	Implementation Barriers and Facilitators	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	3 months
Secondary	Moderate or vigorous physical activity (according to IPAQ-short)	to compare proportion of individuals who perform at the end of the follow-up moderate or vigorous physical activity	3 months
Secondary	Cardioprotective diet adherence	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
Secondary	Global DNA Methylation	participants' global DNA methylation using the RRBS method (Reduced Representation Bisulfite Sequencing).	Baseline and 3 months
Secondary	weight	to compare mean weight (kg) between groups	3 months
Secondary	HbA1c	to compare mean HbA1c(%) between groups	3 months
Secondary	Glycemia	to compare mean Glycemia (mg/dL) between groups	3 months
