IMPACT OF SEDENTARY BEHAVIOR ON MATERNAL AND FETAL OUTCOMES IN PRIMIPAROUS PREGNANCY

Abstract

Objective: Sedentary behavior is a risk factor for the development of diseases, physical activity is a means of change, and can help in prevention and provide benefits to mother and baby, thus the need to analyze the impact of these factors on the pregnancy of primiparous women. Methods: Cross-sectional observational study, carried out at the Darcy Vargas Maternity Hospital, Joinville-SC, from August to December 2020. Sample composed of primiparous puerperal women who answered a validated questionnaire (QAFG) on physical activity; The primary outcomes analyzed were: gestational weight gain, gestational diabetes mellitus (GDM), hypertensive disease of pregnancy (HPD), mode of delivery, prematurity, newborn weight (NB) and neonatal ICU. The adjusted odds ratio was calculated, with a confidence interval of 95%; The group of sedentary patients was used as the standard. Results: The 492 patients were divided into 4 groups: sedentary puerperal women (n=76/15.4%), light physical activity (152/30.9%), moderate (202/41.0%) and vigorous physical activity (n=62/12.6%). When compared to the sedentary group, the light physical activity group showed protection against the development of GDM with 0.4 OR (95%CI 0.2-0.8) and admission to the neonatal ICU with 0.2 OR (95%CI 0.1-0.7). The moderate group also reduced the chance of developing GDM with a CR of 0.4 (95%CI 0.2-0.9) and admission to a neonatal ICU with a CR of 0.3 (95%CI 0.1-0.9); The vigorous group did not have significant results. Conclusion: Sedentary behavior, when compared to the practice of light and moderate physical activity during primiparous pregnancy, increased the chances of developing GDM and the need for hospitalization in the neonatal ICU.
