Background: Pregnancy is defined as term between 37 weeks 0 days and 41 weeks 6 days.Recent evidence indicates that infants delivered at 37 and 38 weeks’ gestation, are at an increased risk for morbidity compared to infants delivered at 39 weeks.The aim of this study is to assess the foetal outcome according to the weeks of gestation in spontaneous vaginal delivery occurring between 37 weeks to 42 completed weeks of gestation. Materials and methods: This prospective Observational study was conducted in postgraduate department of Obstetrics and Gynecology at SMGS Hospital, GMC Jammu over a period of one year.All women who underwent spontaneous vaginal delivery and satisfied the inclusion and exclusion criteria were included in the study. Results: Out of 250 patients who delivered spontaneously between 37 to 42 weeks, it was observed that the foetal outcome was the best among patients who delivered between 39-40 weeks of gestation. Their average birth weight (3.12 kg) and apgar score (9.86) was the highest while nicu admission rate (3.6%) was the lowest as compared to those who delivered before and after them. Conclusion: These results suggest that the likelihood of foetal morbidity varies between early term and full term. It is best to avoid elective LSCS or unnecessary labour induction before 39 weeks in order to achieve the best foetal outcome.
