[Perception of barriers and facilitators for users to participate in physical activity programs].

In Brazil, physical activity is a priority area in health promotion in the Brazilian Unified National Health System (SUS). The study aims to describe users' profiles and the barriers and facilitators in basic healthcare for participation in programs to promote physical activity. This was a statewide cross-sectional study in municipalities (counties) in Pernambuco State. Between 2 and 21 individuals were interviewed per municipality, using a previous tested instrument, validated in the following dimensions: sociodemographic; health status; participation; information on the program; reasons for participation; facilitators; barriers; and preference of activities. Descriptive and inferential analyses (chi-square) were performed. The sample consisted of 1,153 users, 35.9% of whom between 41-59 years of age; 90.1% lived in urban areas; 58.2% had participated in physical activities for at least a year. Weekly frequency of 3-4 days was 44.9%, and 71.1% practiced activities of an hour or more. The results showed that 40% of the barriers to participation in physical activity programs and 77.5% of the facilitators belonged to the intrapersonal domain. The most prevalent barrier was "current health condition" and the facilitator was the desire "to be healthier". Women perceived more barriers than men. The conclusion is that barriers and facilitators from the intrapersonal domain, related to health, are the main factors involved in users' engagement and retention in programs and interventions to promote physical activity, developed in basic healthcare services in the state of Pernambuco.
