Methods: In a prospective study, physical activity of 374 pregnant women was measured using Pregnancy Physical Activity Questionnaire (PPAQ) during the first half and the second half of pregnancy. Pregnancy outcomes were recorded as birth weight, preterm delivery, hypertension without proteinuria, preeclampsia, mode of delivery, and gestational diabetes. Results: There was a significant decrease in values of self-reported physical activity from the first half of pregnancy to the second half of pregnancy in light (P <0.001), moderate (P <0.001), vigorous (P= 0.029), total (P <0.001) intensity. The women with the highest tertile of total physical activity in the first half of pregnancy had significantly lower adjusted odds (OR: 0.07, 95% CI: 0.02-0.32) of having a macrosomia newborn and higher adjusted odds (OR: 6.44, 95% CI: 1.38-30.14) of having a low birth weight infant. The risks of cesarean section for women in the highest category of total physical activity in the second half of pregnancy was higher those in the lower and lowest category (OR: 1.89, 95% CI: 0.29-3.36). Conclusion: It is necessary to emphasis on physical activity guideline for reduction of pregnancy complications. LA eng UL http://caspjrm.ir/article-1-174-en.html M3 10.22088/caspjrm.4.2.10 ER -
