The author aimed to evaluate distribution and associated factors of preterm singleton delivery (PTD) at Pakkred Hospital between 2014 to 2019. This retrospective case-control study included 130 PTD cases and 130 term cases. Associated factors were analyzed by chi-square, Fisher’s exact test and correlation analysis. Multivariable logistic regression was used to calculate odds ratio (OR) and 95% confidence intervals (95%CI). Kaplan-Meier method was used to evaluate median time to delivery. Predictive factors for PTD were late antenatal care (OR=1.87, 95%CI: 1.03, 3.38), preterm labor (OR=3.59, 95%CI: 1.69, 7.63), preterm premature ruptured of membrane [preterm PROM] (OR=4.28, 95%CI: 2.25, 8.15) and pregnancy induced hypertension (OR=15.05, 95%CI: 1.47, 154.04). The provider-initiated PTD [PIPTD] cases were 17.7 percent out of all PTD cases (23/130). Predictive factors for PIPTD were chronic hypertension (OR=56.33, 95%CI: 3.02, 1050.40), previous C-section (OR=179.05, 95%CI: 22.26, 1440.53) and non-vertex fetal position (OR=53.15, 95%CI: 7.95, 355.36). Half of women, who had preterm Labor, preterm PROM and abnormal urinalysis, gave birth in 7.80, 9.00 and 23.63 hours, respectively. Half of women, who had preterm PIH and preterm APH, gave birth in 0.20 and 1.61 days. Thus, working on chronic hypertension in reproductive-age women and reducing C-section rate might reduce PIPTD for further preterm birth reduction in the community hospital.
