Abstract

Objectives: We investigated the association between maternal leukocyte telomere length (LTL) in the immediate postpartum period and moderate to late preterm birth (32- < 37 weeks) among Latinas, a population at high risk for preterm birth.

Methods: Maternal LTL was measured using quantitative polymerase chain reaction at delivery in a prospective San Francisco primarily Latina birth cohort. Logistic regression models were used to investigate the association between postpartum maternal LTL and preterm birth. Maternal LTL was analyzed as a continuous predictor.

Results: Out of 194 participants, 23 (11.9%) had preterm delivery. Longer postnatal maternal LTL was associated with preterm birth (crude OR 4.68; 95% confidence interval (CI) 1.07, 20.6, p = 0.039; adjusted OR 12.8, 95% CI 1.83, 99.9, p = 0.010). Age-stratified analysis showed that being under 35 years increased the effect size of the association between maternal LTL and preterm birth (adjusted OR 32.5, 95% CI 2.58, 597, p < 0.01).

Conclusions for practice: Latina mothers with moderate to late preterm infants had longer LTL in the immediate postpartum period compared to those with term infants. This association was stronger for mothers under the age of 35 years. LTL may serve as a biomarker to better understand the pathophysiology and risk of preterm birth and could inform targeted interventions for prevention and early detection. Future studies are needed to understand physiological changes in maternal LTL from the prenatal to postnatal period in relation to birth outcomes.

期刊介绍： Maternal and Child Health Journal is the first exclusive forum to advance the scientific and professional knowledge base of the maternal and child health (MCH) field. This bimonthly provides peer-reviewed papers addressing the following areas of MCH practice, policy, and research: MCH epidemiology, demography, and health status assessment Innovative MCH service initiatives Implementation of MCH programs MCH policy analysis and advocacy MCH professional development. Exploring the full spectrum of the MCH field, Maternal and Child Health Journal is an important tool for practitioners as well as academics in public health, obstetrics, gynecology, prenatal medicine, pediatrics, and neonatology. Sponsors include the Association of Maternal and Child Health Programs (AMCHP), the Association of Teachers of Maternal and Child Health (ATMCH), and CityMatCH.
