We investigated the association between exercise during pregnancy and risk of miscarriage among more than 90,000 pregnant women. Information on exposures was obtained by means of computer-assisted telephone interviews. A relation was found between the amount of exercise and the risk of miscarriage with the risk of miscarriage rising stepwise by the amount of exercise performed. Particularly "high impact exercise" was associated with an increased risk of miscarriage. No association was seen between exercise and risk of miscarriage after 18 weeks of gestation.
