RESUMO
BACKGROUND: The purpose of this study was to determine the impact of evidence-based educational materials and access to local resources on physical activity (PA) levels, beliefs, and motivation (including self-efficacy) regarding PA during pregnancy in a rural setting. METHODS: Information on PA levels (step counts, Pregnancy Physical Activity Questionnaire) and beliefs and motivation regarding PA (main surveys: Exercise Beliefs Questionnaire, Protection Motivation Theory and Health Action Process Approach) were collected between 8 and 16 weeks gestation. Women from a rural community were randomly assigned to the PA group (PAG, n = 38) or control group (n = 32). The PAG participants received an evidence-based educational brochure and access (at no charge to them) to local fitness facilities. At approximately 34 to 37 weeks gestation, baseline assessments were repeated. RESULTS: Sedentary time was significantly different between groups over time, with control participants increasing sedentary time and PAG participants decreasing sedentary time (P = .04). Sixteen women (42%) in the PAG utilized the resources provided (prenatal yoga being utilized most). Postintervention, there was a significant group × time interaction for Perceived Self-Efficacy scores; scores in the PAG remained consistent with baseline values, whereas scores in the control group decreased (P = .03). CONCLUSIONS: The intervention reduced sedentary time and maintained self-efficacy scores during pregnancy.
