Comportamento de movimento durante a gravidez e desfechos materno-fetais em mulheres com diabetes gestacional

Abstract

Gestational diabetes mellitus (GDM) is one of the most common medical complications in pregnancy. GDM is associated with a higher risk for adverse maternal–fetal outcomes. Adequate movement behavour (MB) (physically active and low sedendentary behavour (SB)) could be buit a health protect effect. Associations between MB, including physical activity (PA) and SB, and maternal–fetal outcomes on GDM are still unclear. The objective of this study was to investigate associations between MB and adverse maternal–fetal outcomes in women with GDM. A total of 68 women with GDM (20–35 weeks, 32.1 ± 5.8 years) were included in this pilot casecontrol study. The cases were defined by the presence of an adverse composite maternal–fetal outcome (preterm birth, newborn large for gestational age, and neonatal hypoglycemia). Controls were defined as no adverse maternal–fetal outcome. PA intensities and domains, steps/day (pedometer), and SB were analyzed. A total of 35.3% of participants showed adverse maternal–fetal outcomes (n = 24). The controls showed a higher moderate-intensity PA level than the cases (7.5, 95%CI 3.6–22.9 vs. 3.1, 95%CI 0.4–10.3 MET-h/week; p = 0.04). The moderate-intensity PA level was associated with a lower risk for adverse maternal–fetal outcomes (OR 0.21, 95%CI 0.05–0.91). No significant associations were observed for other PA and SB measures (p > 0.05). In conclusion, moderate-intensity PA during pregnancy seems to have a protective role against adverse maternal–fetal outcomes in women with GDM.
