摘要

Background and objectives

Postpartum anemia is a significant public health concern affecting both maternal and infant health. This study aimed to investigate the relationship between maternal anemia during pregnancy, and infant anthropometric measurements at one month postpartum, as well as postpartum anemia in mothers and infants.

Methods

Data from the Social Transfer for Exclusive Breastfeeding (STEB) randomized controlled trial in Vientiane, Lao People’s Democratic Republic (Lao PDR), were analyzed. Linear and logistic regression models were used to calculate adjusted estimates, including beta and odds ratios, and 95% confidence intervals (CI) for maternal hemoglobin (Hb) levels and anemic status during pregnancy and at one month postpartum. Primary outcomes were infant anthropometric measurements, with secondary outcomes including infant and maternal Hb levels and anemic status at one month postpartum.

Results

At one month postpartum, we identified 298 mothers (mean age: 27 years) and their healthy term infants who were born at a healthy birth weight. No significant association was found between maternal anemic status (yes/no) and Hb levels during pregnancy and infant anthropometric measurements at one month postpartum. A positive association was observed between maternal and infant Hb levels at one month postpartum, with a 0.2 g/L increase in infant Hb for every 1 unit increase in maternal Hb (β = 0.23, 95% CI: 0.05, 0.40, p < 0.01).

Conclusion

These findings highlight the importance of early postpartum intervention and continued nutritional care for both mothers and infants during the postpartum period, especially for mothers who experienced anemia during pregnancy. Further research is needed to explore the long-term effects of maternal postpartum health on infant development and growth.
