title: Hyperemesis Incidence in Planned versus Unplanned Pregnancy.
abstract: OBJECTIVE
  We evaluated the incidence of hyperemesis between planned and unplanned pregnancy.
  
  
  METHODS
  A prospective study was conducted among 100 women with planned pregnancies and 100 women with unplanned pregnancies. Participants completed a questionnaire to determine the presence of vomiting. If pregnant women had severe vomiting (>3 times per day), urinary investigation was performed; at least one positive ketonuria was considered as hyperemesis.
  
  
  RESULTS
  There was a significant difference between planned and unplanned pregnancy in terms of the incidence of hyperemesis (p=0.0001). Women with unplanned pregnancies had a more than 18-fold increased risk of hyperemesis (OR=18.88; %95 CI, 8.84-40.31) compared to women with planned pregnancies.
  
  
  CONCLUSIONS
  Healthy women may be able to improve their management of hyperemesis during pregnancy if they plan their pregnancies.
