Tóm tắt

 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.
