Due to importance of breast feeding on physical and mental health of     infants , it   is   necessary  to  recognize  the  influenting factors  on the time     duration  of  breast  feeding .  The   present   investigation  is   designed  to     determine   the   relationship  between  environmental  tobacco  smoking     (E.T.S) and Breast feeding  duration  (B.F.D)  among women reffered to the     health   centers   supervised   by   Shaheed   Beheshty  University  of Tehran     in 1998.          A cohort   study  was  performed  on 70 women which were in a smoky     environment during their pregnancy ,  Breast  feeding ( exposure ), and 70     women which were in a smoke  free   environment  ( Non  exposure ). Our     exposure   and   non   exposure   groups   were   matched   for  their age .     education , profession and  type of   delivery.   Sampling   was  based   on     nonprobablistic method . Relative  risk  and  attributable  rate of  E.T.S and     B.F.D  were calculated.          The   B.F.D   parameter   were   obtained   as  3.91.3   in  the  group of     exposuer and 4.81.3 for non exposure  group (P<0.001). In  the  exposure     57% of  women had more than 4.5 month of exclusive breast feeding and     in non exposure group this was 31% (P<0.001).          Breast   feeding   duration  is  decreased  for women being in an smoky     environment.
