Abstract

Objective: The study aimed at identifying the prevalence of preterm labor and the associated risk factors. Design: A quantitative approach using retrospective case control study. Setting: Tertiary care hospital of Udupi district Karnataka. Population or Sample: Women delivered in tertiary care hospital of Udupi district Karnataka were the sample, among them the cases (250) were the records of the women who had delivered before 37 weeks of gestation and controls (500) were the records of women who delivered after 37 weeks of gestation and without any complications. Method: The study was conducted using, retrospective case-control design by reviewing the case records of women who had delivered in a tertiary care hospital. Main Outcome Measures: Women delivered in tertiary care hospital of Udupi district Karnataka, their inpatient records were assessed for the risk factors during the antenatal period and the period of delivery. Results: The study revealed that the prevalence of preterm labor was 356 (14.86%) Out of 2402 deliveries. Among them only 250 were assessed. It was significantly correlated with age, place of residence, degree of education, occupation, marital status, gravid para, and number of deliveries, type of deliveries, gap between births, blood type, and religion. Pregnant women who had been exposed or had risk for preterm labour included those who had been diagnosed with pregnancy-induced hypertension, medication during pregnancy, history of abortion, intense physical labour, and conception dates older than 30 years. Conclusion: The preterm labor prevalence can be minimized if the modifiable risk factors are in control. Non-Modifiable risk factors require keen supervision. Thus the health professional needs to be alert about all the modifiable and non-modifiable risk factors. Keywords: preterm labor, prevalence, risk factors Background: Preterm labor can be prevented if detected earlier, thus to determine the risk factors of preterm labor, the present study was conducted to identify preventive measures. The study was conducted in the tertiary care hospital of Udupi district using retrospective case-control design for identifying the prevalence and the risk factors of preterm labor by reviewing the case records of women who had delivered in a tertiary care hospital. The study revealed that the prevalence of preterm labor was 356 (14.86%) Out of 2402 deliveries. Among this 356 preterm labor, only 250 samples were assessed randomly for identifying the risk factors of preterm labor as per the sample size calculation. A significant association was found between preterm labor and age, residence, education level, occupation, marital status, gravid para (number of conception), number of deliveries, type of delivery, birth interval, blood group, and religion. The number of preterm labor were seen among the pregnant women who had been exposed and were proved to be at risk if they were diagnosed with pregnancy-induced hypertension, previous abortion, hard physical work, and age of conception above 30 years. The preterm labor prevalence can be minimized if the modifiable risk factors are in control. Non- Modifiable risk factors require keen supervision to prevent preterm labor.
