Spontaneous preterm labor risk factors include multiple gestation, inadequate prenatal care, and gestational bleeding. Addressing maternal work status and nutrition can help prevent preterm birth.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Medicine
  • Reproductive Health

Context:

  • Preterm birth is a leading cause of neonatal morbidity and mortality.
  • Existing research often aggregates different types of preterm birth, limiting understanding of specific risk factors.
  • Distinguishing between spontaneous preterm labor, preterm premature rupture of membranes, and medically indicated preterm birth is crucial for targeted interventions.

Purpose:

  • To determine the proportion of spontaneous preterm labor, preterm premature rupture of membranes, and medically indicated preterm births.
  • To identify specific risk factors associated with spontaneous preterm labor in a cohort of women delivering at tertiary care centers.

Summary:

  • A case-control study analyzed 385 women with preterm births and 357 controls with term births.

  • Preterm births comprised 29% spontaneous preterm labor, 49% preterm premature rupture of membranes, and 22% medically indicated.
  • Risk factors for spontaneous preterm labor included multiple gestation, lack of paid work, fewer than six prenatal visits, low arm circumference, prior preterm birth or low birth weight, and gestational bleeding.

    • Impact:

    • Identifies key modifiable risk factors for spontaneous preterm labor, such as prenatal care utilization, maternal employment, and nutritional status.
    • Highlights the importance of differentiating preterm birth subtypes for effective prevention strategies.
    • Provides evidence to inform public health initiatives and clinical practice aimed at reducing preterm birth rates.
