An interventional study of VAMOS Program in Sedentary Lifestyle, sponsored by Universidade Federal de Santa Catarina. Completed at 1 site in Brazil. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-03-31.
Sponsored by Universidade Federal de Santa Catarina · Not applicable, Interventional, and Prevention
The main purpose of this study is to evaluate the effectiveness and the maintenance of a behavior change program called VAMOS (Active Life Improving Health) Program on physical activity and healthy eating habits in different environmental contexts of Florianópolis/ SC/ Brazil. This study will be conducted in Health Centers (HC) of Florianópolis/ SC/ Brazil, defined according to environmental and income characteristics. Therefore, initially all geographic areas around the HC will be visited to classify the public places as favorable (with the presence of spaces for the practice of PA) and unfavorable environmental (do not have spaces for physical activity). Thereafter, four HC will be selected: high income + high environmental quality index, high income + low environmental quality index, low income + high environmental quality index, low income + low environmental quality index. In each HC, the volunteers will be randomly assigned into two groups of approximately 25 people: VAMOS group and control group. The participants that will be assigned to the VAMOS group will participate in a behavioral change program aimed at motivating changes in physical activity and eating habits during five months (12 meetings - six weekly meetings and six fortnightly meetings), while the control group will receive one educational lecture regarding lifestyle changes. The meetings of VAMOS Program will be held in the dependences or nearby the HC and will be mediated by the physical education professional previously trained. The Program will be evaluated by the RE-AIM framework: reach, effectiveness, adoption, implementation and maintenance. The effectiveness will be assessed from measurements of physical activity, eating habits, self-efficacy, social support, quality of life, anthropometry, and lipid profile before and after five months of intervention. The implementation will be assessed by identifying the extent to which the program will be conducted as planned. The maintenance will be estimated from revaluations of all outcomes, as measured before and after the intervention, six months and one year after the end of the program.

Therefore, initially all geographic areas around the HC will be visited to classify the public places as favorable (with the presence of spaces for the practice of PA) and unfavorable environmental (do not have spaces for physical activity), using the instrument Physical Activity Resource Assessment (PARA). Thereafter, four HC will be selected: high income + high environmental quality index, high income + low environmental quality index, low income + high environmental quality index, low income + low environmental quality index. In each HC, the volunteers will be randomly assigned into two groups of approximately 25 people: VAMOS group and control group, resulting in a total sample of approximately 200 volunteer users. The volunteers will be invited to attend a lecture on healthy lifestyle in date, place and time set, in which a screening will be held in order to trace the profile of the population reached. On this occasion, a questionnaire containing information of sociodemographic data, health status, quality of life, physical activity, eating habits will be answered. They also will be asked to report their individual height and body mass. The participants that will be assigned to the VAMOS group will participate in a behavioral change program aimed at motivating changes in physical activity and eating habits during five months (12 meetings - six weekly meetings and six fortnightly meetings), while the control group will receive one educational lecture regarding lifestyle changes.

The maintenance will be estimated from revaluations of all outcomes, as measured before and after the intervention, six months and one year after the end of the program. For data analysis, in addition to descriptive statistics, two-way ANOVA for mixed models will be applied for within and between groups comparison, if the premises of this test are met. The level of significance that will be adopted is P\<0.05. All analyzes will be done at SPSS statistical package, version 17.0.
Universidade Federal de Santa Catarina is the lead sponsor of 24 studies on the registry; 2 are open to participants now.

Exclusion Criteria:
Active life improving health: all participants that will be assigned to change behavior group will participate of a change behavior program, entitled VAMOS (Active Life Improving Health), for five months. The VAMOS Program is a lifestyle promotion program, that includes physical activity and healthy eating habits. The program is composed by 12 meetings (six weekly meetings and six fortnightly meetings), in group, lasting about 90 min. In each In each weekly meeting, will be discussed guidelines and strategies for physical activities practices in different domains and for adoption of a healthy diet. All aspects and strategies included in the program are based in behavior changes theories.

change in physical activity
Habitual physical activity will be assessed by GT3X or GT3X+ accelerometer (Actigraph - USA) and Actilife 6.10 software will be used to analysis. Each participant will be instructed to use the accelerometer for seven consecutive days, removing it only for sleeping, bathing or performing water activities. The device will be attached to an elastic belt and fixed in the right side of the hip. Data will be collected in a 30 Hz sample frequency and will be analyzed using 60-s epochs. Periods with consecutive values of zero (with 2-min of spike tolerance) for 60 min or longer will be interpreted as "accelerometer not worn" and excluded from the analysis. Physical activity data only will be included if the participant accumulate a minimum of 10 hours/day of recording for at least four days, including one weekend day
Time frame: baseline, 5 months, 11 months, 17 months
change in eating habits
Eating habits will be investigated from the score generated by the food frequency questionnaire, using questions from previous studies (Brasil, 2014; Lopes, 2010). The questionnaire will be applied, using a list of foods for which the average frequency of consumption over the last three months is given.
