Clinical and Demographic Factors Associated with Preterm Labor in Twin Pregnancies at Mardan Medical Complex

Twin pregnancies (TP) were often associated with preterm labor due to excessive dilation of the endometrium. Most twin pregnancies result in delivery before 37 weeks of gestation. In this study, which did not focus on cervical selection, the average pregnancy duration was 35.83 ± 8.7 weeks, with 50% of the babies delivered before 37 weeks. Objective: To figure out how frequently twin pregnancies that present at Mardan Medical Complex, Mardan, result in preterm labor. Methods: This descriptive case series was conducted over six months, from January 1st, 2022, to June 30th, 2022, in the Obstetrics and Gynaecology Department of Mardan Medical Complex. The study included 98 women pregnant with twins, and each was followed up until 36 weeks of pregnancy. Data analysis was performed using SPSS version 23.0. Results: There was a significant association between preterm labor and maternal weight. Women weighing 70 kg or less had a higher rate of preterm labor (55.7%) compared to those weighing more than 70 kg (35.1%) with a p-value of 0.048. Preterm labor occurred in 49.2% of women aged 18-30 years and 45.5% of those over 30 years (p=0.724). Conclusions: Maternal weight appears to be a key factor in the risk of preterm labor. Future studies should investigate the impact of weight on preterm labor and explore weight management interventions as part of antenatal care.
