title: Beliefs about exercise and physical activity among pregnant women.
abstract: OBJECTIVE
  The objective of this study was to document self-reported beliefs about physical activity and exercise among pregnant women.
  
  
  METHODS
  The Pregnancy, Infection, and Nutrition (PIN3) Study asked 1306 pregnant women about beliefs regarding physical activity and exercise at 27-30 weeks' gestation.
  
  
  RESULTS
  While 78% of women agreed that most women can continue their regular exercise during pregnancy, fewer (68%) agreed that most women who never exercised could begin an exercise program during pregnancy. Most (89%) agreed that regular exercise was better than irregular exercise during pregnancy. While almost all women agreed with the benefits of light activity (98%), fewer agreed that there were benefits with moderate (73%) or vigorous exercise (13%). Differences in beliefs were most notable by educational level, race/ethnicity, and whether they participated in regular exercise during pregnancy.
  
  
  CONCLUSIONS
  Future studies can better elucidate the reasons behind the differences in beliefs, to explore whether cultural reasons are contributing to these differences and whether tailored messages would be more effective than general educational approaches.
  
  
  CONCLUSIONS
  This study provides information to create more successful interventions to help women understand concepts regarding the safety and benefits of physical activity during pregnancy.
