Background: One of the most important health determinants is social vulnerability, which can interfere in the practice of physical activity (PA). This study aimed at analyzing adherence to a PA program in a high social vulnerability context. Methods: A longitudinal study with a 6-month intervention period was conducted. The program offered monitored walks associated with behavioral change educational campaigns. Sociodemographic characteristics, occupation, PA level, noncommunicable chronic diseases, participants’ frequency of participation in the program, and intervention dropout reasons were evaluated. Descriptive and survival analyses were accomplished. Results: Among the 106 participants, 88.0% were female and 21.7% were older adults. The most mentioned participation reasons were health improvement (23.0%), weight loss (19.0%), disease control (17.0%), and social living (12%). The mean frequency of participation in the program was 27.4%. Dropout rate was 52.7%. The main reported reasons for dropping out were work hours (27.8%), health problems (25.9%), personal reasons (22.2%), and lack of time (11.1%). Factors associated with remaining in the program were being older adults and presenting body mass index <25 kg/m2. Conclusions: Results showed that in a high social vulnerability context, adherence to PA programs is low, and adult-life-related commitments and high levels of obesity are factors associated with lower adherence.

Background: Some studies have used the follow-up method to analyze real behavioral changes in research involving physical activity (PA) interventions. This has great scientific value; however, it is hard to apply without satisfactory resources and research funding. Little is known about how many studies have used this method to analyze PA interventions in low-income and middle-income countries, especially Brazil. Purpose: To describe Brazilian studies using follow-up analysis after PA interventions. Methods: A systematic review was performed including Brazilian studies with follow-up analysis after PA interventions; the analyzed papers were from the previous 10 years. The search was carried out in Portuguese, English, and Spanish in the following databases: SciELO, Latin American and Caribbean Health Science Literature, PubMed, and Scopus. The Preferred Reporting Items for Systematic Review and Meta-Analysis method was used. Results: In total, 6 of the 7 studies analyzed were from the southeast region, with the intervention time ranging from 2 to 12 months, carrying out follow-up every 5.3 months with 2.2 observations on average. The interventions had a behavioral approach and were generally carried out in universities, hospitals, and ambulatory care. Conclusion: Studies on PA interventions using follow-up analysis are scarce. Considering the relevance of follow-up studies to measure behavior changes, the results suggest that more studies about this topic are essential in Brazil.
