Evaluation of Risk Factors for Preterm Birth Outcome in Gujarat, India

Background: Preterm birth (PTB) is a leading cause of neonatal survival complications, mortality, and morbidity worldwide. In India 35% of all neonatal deaths are due to PTB with 36th global ranking, hence, India's healthcare sector has been working towards reducing the rate of PTB effectively.Objective: This study aimed to assess the risk factors such as environmental and pathophysiological causes associated with preterm birth in the population of Gujarat, India.Materials and Methods: In this study, multivariate random sampling was performed and systematically 200 pregnant mothers [PTB 37 weeks (N=100)] were chosen after excluding mothers with vaginal infection, multiple gestations, fetal anomalies, non-cephalic presentation, cesarean delivery, and pregnancy with Mullerian anomalies. Statistical analysis was performed by Chi-square test, and variables with p-value <0.05 were considered statistically significant.Results: Out of all the variables, maternal age below 20 years, extreme BMI, high blood pressure during pregnancy, maternal health complications, medication and doctor's consultation were highly significant (p < 0.0001). Furthermore, variables like type of area, diet, education, Hb levels below 9 g/dL and above 13 g/dL and blood-group of the mother were also significantly associated with PTB outcome (p < 0.05). Among the sub-categories of PTB (extreme-, very-, moderate/late- PTB), maternal age, Hb level and the past obstetric outcome showed very high significance (p < 0.0001).Conclusion: For the prediction of birth outcome, mother's internal physiological and lifestyle factors need to be taken into consideration, and mothers at risk priorly can be screen out, followed by proper healthcare assistance to decrease the preterm birth rate and its consequences.Key words: Preterm birth, maternal age, blood pressure, past obstetric outcome, risk factors
