Abstract

Introduction: The practice of physical activity (PA) during pregnancy and the postpartum period is recommended as it brings several benefits to the pregnant woman and the fetus, while sedentary behavior (SB) may be associated with greater risks for both. No studies were found that carried out objective measurements of PA and SB in Brazilian pregnant and postpartum women, not allowing us to understand whether this population complies with current recommendations. Objectives: To describe the level of PA and CS in pregnant and postpartum women, compare these levels throughout the pregnancy and puerperal cycle and verify the influence of the level of PA and CS on maternal and neonatal outcomes. Methods: Longitudinal observational study, which will include pregnant women in the 2nd trimester. The ActivPAL¿ device will be used to objectively measure PA and CS, and an anamnesis form to verify maternal and neonatal outcomes. Three assessments will be carried out: 2nd and 3rd gestational trimesters and 3 months postpartum. To analyze the relationship between the studied variables, regression models will be used. Expected results: It is expected that, based on knowledge of the PA levels and CS pattern of this population, it will be possible to contribute to the formulation of more effective intervention strategies to promote maternal and neonatal health, in addition to enabling new studies on the topic. The study also aims to develop educational materials and contribute to public guidelines on women's health.
