The   preterm   birth  is one of the  main  health problems and the most    common   cause  of  prenatal   and  neonatal  death. The  objective of this    study was to determine the prevalence of preterm birth and its risk factors.          We conducted  cross-sectional study with 1087 sample of networks who    were the   total of  births of Babol for three months in three hospital in 1998.    The   data were  collected  by  determining gestational age using LMP and    interviewing  with  mothers. We  used  multiple  logistic regression analysis to    estimate the standardized relative risk(RR).          The   result   showed  the  prevalence  of  preterm birth was 9% with 95%    confidence  interval (7.3% , 10.7%). The risk of  preterm  birth  was increased    2.71 times significantly among women with hypertension during pregnancy    (P<0.01). The relative risk was 2.64 folds (P<0.05) among twins and 1.75 folds    (P<0.05) among women with a history of abortion. The risk  of  preterm birth    was decreased in private hospital(RR=0.58,P<0.05). In the stepwise multiple    logistic regression  analysis  only  the   effect  of hypertension in pregnancy    (RR=3.35, P<0.01) and being twin (OR=2.64, P<0.05) and having a history of    abortion (RR=1.80, P<0.05) significantly  increased  the  risk  of preterm birth    and among  private  hospital  (OR=0.57, P<0.05) , the  risk  was  decreased    significantly.          Therefore , with   eliminating  the  obstacle  of  prenatal   care and with    creating health services, the surveillance system  should  perform  especial    care  in  high  risk   pregnancies , especially ,  for  women  with  a  history of    abortion , and hypertension and twin gestation. Thus surveillance program,    continuing education , consultation and coordination between clinics and    health centers contribute prevent the preterm birth.
