Association between maternal height and mode of delivery among nulliparous pregnant women delivered at tertiary care hospital

Objective: To observe the impact of maternal height upon mode of delivery among nulliparous women. Maternal and neonatal morbidities are secondary aims associated with this study. Material and Methods: This study is prospective observational study which is carried out at Department of Obstetrics and Gynaecology, Combined Military Hospital, Rawalpindi, from   1st January 2024 to 31st December 2024. A total of 350 pregnant women, with age range 20 years to 30 years selected who were admitted with labor pain in between 38 weeks to 40 weeks of gestation. Mode of delivery with different height of patient was obtained. Data was analyzed by using SPSS version 23 and p value of <0.05 was considered statistically significant. Results: The mean maternal age of patients is 25.06±5.07 years, with the majority (61.71%) having a height between 150–159 cm. , The percentage of normal vaginal delivery increases with increasing maternal height 51.3% (<150cm), 60.2% (150-159cm) and 74.7% (>159cm). The chi- square test indicates a statistically significant association between maternal height and the mode of delivery. The rate of caesarean section decreases with increasing maternal height, 38.5% (<150cm), 36.1% ( 150-159cm) and 23.2% (>159cm). Our study demonstrates the significant association between low maternal height (<150 cm) and increased likelihood of cesarean delivery (CD). Conclusion:This study highlights the significant associations between maternal height and various delivery outcomes, emphasizing the need for further investigation into how these factors can influence clinical practices to improve maternal and neonatal health.
