Brief Summary

The study aims to verify if the VAMOS strategy contributes to an increase in physical activity and healthy eating habits among users of the Health Academy Program from Belo Horizonte, Minas Gerais.

Detailed Description

The Health Academy Program (AP) is a important policy to promote physical activity in Brazil. There are areas with infrastructure, equipment, and human resources to stimulate and guide people doing physical activity in community settings at no cost. The study aims to verify if the VAMOS strategy contributes to an increase in physical activity and healthy eating habits among users of the Health Academy Program (AP) at Belo Horizonte, Minas Gerais - "VAMOS BEAGÁ". Two AP poles, both belonging the same regional administration of the municipality and with the same health vulnerability index were selected. To define the location of the intervention VAMOS was carried draw between the selected centers, and all potentially eligible users invited to participate. Users of the Intervention Group (IG) took part in the daily activities offered by AP and, additionally, for 12 weeks, they attended the educational strategy called VAMOS. The Control Group does only the regular activities of AP. The VAMOS has been evaluated by the dimensions of Reach, Effectiveness, Adoption (at the individual level), Implementation and Maintenance (at individual and organizational level) of the RE-AIM model (Reach, Efficacy / Effectiveness, Adoption, Implementation, Maintenance). The reach is evaluated by the rate of participation and representation among participants and those invited to join the VAMOS. The effectiveness has been evaluated from anthropometric measurements, eating habits, physical activity level, stages of change, self-efficacy, social support and quality of life before and after 12 weeks of intervention. To assess the adoption was investigated the interest of Physical Activity professional from AP in mediating this strategy in future. The implementation was evaluated by identifying the extent to which the VAMOS was conducted as planned. The maintenance, at individual level, will be estimated from revaluations of all outcomes, as measured before and after the intervention, sixs months after the conclusion of the intervention. At organizational level, the maintenance will be accessed with semi-structured interviews conducted with the coordinators and managers of AP assessed feasibility of continuing of VAMOS strategy in AP. For the analysis of qualitative data will be conducted content analysis. And to the quantitative data, we carried out descriptive statistics, paired tests chi-square or Fisher's exact and two-way ANOVA for repeated measures or Wilcoxon signed rank test. Intent-to-treat analyzes were used. The significance level was 5% and the statistical program used was the Statistical Package for Social Sciences (SPSS) for Windows.
