BACKGROUND
Preterm birth is a leading cause of infant death and the role of maternal physical activity on this risk remains unclear. This systematic review examined low, moderate and vigorous leisure-time physical activity (LTPA) during pregnancy and the outcome of preterm birth.

METHODS
Key words related to preterm birth and physical activity were used to search relevant databases (Medline, Cochrane, CINAHL, Sports Discuss and Scopus). Studies were excluded if they did not measure physical activity as an exposure in pregnant women, did not provide information on gestational age at delivery, and were not published in English. All study designs and sample sizes were considered.

RESULTS
The search generated 1472 studies. There were 27 studies included in this review of which 23 received high quality reporting scores. Eleven studies reported a lower risk of preterm birth for women who performed LTPA during pregnancy, while 14 studies reported null findings. Only 2 studies detected a significantly higher risk of preterm birth with LTPA during pregnancy.

CONCLUSION
This review of literature up to 2014 provides additional evidence to support the assertion that healthy pregnant women can engage in low, moderate, and even some vigorous levels of LTPA without risk for preterm birth.
