Objective:   To compare the fetomaternal outcome in women with < 18 months versus 18~24 months of interpregnancy birth interval.

Methodology: This prospective cohort study was conducted in Obstetrics & Gynecology, PNS SHIFA Hospital, Karachi September 2016 to March 2017. A total of 82 women with singleton pregnancy and gestational age > 28 weeks were included. Patients with multiple pregnancy, diabetes mellitus, hypertension and uterine rupture were excluded. Two groups (A& B) were formed and the patients according to their inter-pregnancy interval i.e. < 18 months and 18-24 months were distributed in A & B respectively. The fetomaternal outcome i.e. caesarean section, post-partum hemorrhage.pre-eclampsia, preterm delivery, small for gestational age infants and apgar· score <7 at 5 minutes (yes/no)was recorded by following the patients till delivery.

Results: Age range in this study was from 18 to 40 years with mean age of29.78 ± 5.95 years. The maternal outcomes i.e. caesarean section was recorded in 39.02% in group A patients while 9.76% in group B women, preeclampsia was recorded in 26.83% versus 9.76% respectively and postpartum hemorrhage in 29.27% versus 14.63% respectively. Fetal outcome between groups A versus group B as follows; preterm. Delivery in 34.15% versus 12.20%, small [or gestational age infants as 29.27% versus 14.63% and apgar score <7 at 5 minutes in 31.71 % versus 19.51 % respectively with p-value of <0.05.

Conclusion: Our study concluded that short inter pregnancy interval (<18 months) was associated with adverse fetomaternal outcome compared to long interpregnancy interval (18-24 months).
