Objective: To determine the frequency of preterm deliveries in women presenting with threatened abortion at tertiary care hospital. Study design: Cross sectional study. Place & Duration of study: Department of Obstetrics and Gynaecology Unit I, Jinnah Postgraduate Medical Center (JPMC) Karachi, from October 2014 to March 2015. Methodology: Women between 18 year to 45 year of age diagnosed as cases of threatened abortion, were consecutively selected. Patients with non-obstetric causes of bleeding such as cervicitis, vaginitis, cystitis, trauma, significant cervical dilation, ectopic pregnancy, multiple gestations etc were excluded from the study. The variables assessed were maternal age, gestational age and parity. Preterm delivery and obstetrical factors were expressed as frequency and percentages. Stratification of age, gestational age, parity and obstetrical factors was done. Chi square test was applied to the data and p <0.05 was taken as significant. Results: During the study period 105 women were diagnosed as cases with threatened abortion. The mean maternal age was 26.53±6.36 year. Mean gestational age was 29.92±3 weeks while mean parity was 2.30 ±1.18 (range: 1 to 5 children). Frequency of preterm delivery among patients of threatened abortion was 17.14% (n =18). Age was high significant (p = 0.001) effect modifier which decreased more than half from 20.83% in 18-25 year of age to 9.09% in 36-45 year of age. There was no significant difference with variation of gestational age and parity. With any obstetrical condition (pre-eclampsia, eclampsia, HELLP syndrome and placental abruption) much higher frequency of preterm delivery was noted as compared to having none (p = 0.000). Conclusions: The frequency of preterm delivery in patients of threatened abortion was more common in younger age and primigravida.
