Insights

Late preterm infants face breastfeeding challenges but achieve high exclusive breastfeeding rates by one month with support. Prolonged donor milk use indicates a need for intensified lactation support.

Area of Science:

  • Neonatal care
  • Pediatric nutrition
  • Lactation science

Background:

  • Late preterm infants (34-36 6/7 weeks gestation) exhibit increased risks for breastfeeding difficulties compared to term infants.
  • Limited data exists on breastfeeding outcomes and risk factors for non-exclusive breastfeeding in this population.

Purpose of the Study:

  • To assess the exclusive breastfeeding rate at one month in late preterm infants.
  • To identify factors associated with non-exclusive breastfeeding in this cohort.

Main Methods:

  • Secondary analysis of a randomized clinical trial data (August 2023 - May 2024).
  • Included 288 infants, stratified into late preterm and full-term groups.
  • Feeding practices assessed from birth to one month; multivariable logistic regression used to identify risk factors.

Main Results:

  • Late preterm infants experienced longer durations for intravenous fluids, enteral feeding, and direct breastfeeding.
  • Despite initial challenges, the exclusive breastfeeding rate at one month was high (84.84%) and comparable to term infants (84.65%).
  • Prolonged donor milk use was the sole independent predictor of non-exclusive breastfeeding (aOR=1.33; 95% CI [1.04, 1.70]).

Conclusions:

  • Late preterm infants can achieve exclusive breastfeeding rates similar to term infants with adequate support.
  • Prolonged donor milk use may signal a need for enhanced lactation support for mother-infant dyads.

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
