Leisure time physical activity during pregnancy and impact on gestational diabetes mellitus, pre-eclampsia, preterm delivery and birth weight: A review

Abstract

Background. It has been questioned whether leisure time physical activity (LTPA) during pregnancy is beneficial or deleterious to pregnancy outcome, and whether a sedentary lifestyle during pregnancy has a negative impact on pregnancy. Answers to these questions are of general interest, since some young women are very physically active during leisure time, while others have a sedentary lifestyle. Method. In this review, we analysed the association between LTPA and the selected pregnancy outcomes, gestational diabetes mellitus (GDM), pre-eclampsia, preterm delivery, and birth weight. Results. The prevailing literature clearly indicates that LTPA before and/or during pregnancy has a protective effect on the development of GDM and pre-eclampsia. Furthermore, LTPA does not seem to have a negative impact on the rate of preterm delivery or on birth weight. Conclusion. Thus, it seems relevant that health authorities recommend 30 min of daily physical activity to healthy pregnant women. © 2007 Taylor & Francis.
