Dietary Supplements

Maternal probiotics intake during pregnancy and exclusive colostrum breastfeeding are associated with a reduced risk of neonatal jaundice.

TL;DR

Maternal probiotic intake during pregnancy and exclusive colostrum breastfeeding are associated with a reduced risk of neonatal jaundice, highlighting these as important modifiable preventive factors.

Key Findings

Probiotic intake during pregnancy was associated with a significantly reduced odds of neonatal jaundice compared to participants who never used probiotics.

  • Adjusted odds ratio (AOR) of 0.78 (95% CI: 0.61, 0.98), P = 0.041
  • Analysis included 2596 healthy controls and 433 NJ cases with complete data from the CHILD cohort
  • Multivariable logistic regression was used with adjustment for confounders
  • The CHILD cohort was a prospective birth cohort that recruited 3624 mothers and 3542 paired infants

Neonates with exclusive colostrum feeding had a significantly lower incidence of neonatal jaundice compared to other feeding modes.

  • AOR 0.34 (95% CI: 0.27, 0.44), P < 0.001
  • Feeding modes compared included exclusive colostrum, formula-only, and mixed feeding
  • Feeding mode data were collected from hospital birth records
  • This represented the strongest association observed in the study

Mothers who increased probiotic intake during pregnancy compared to preconception levels had a lower risk of neonatal jaundice than those who decreased intake.

  • AOR 0.53 (95% CI: 0.32, 0.89), P = 0.016 for mothers who increased probiotic intake
  • Probiotic intake patterns (increased, maintained, or decreased compared to preconception) were obtained via questionnaires
  • Comparison group was mothers who decreased probiotic intake during pregnancy

Mothers who maintained probiotic intake during pregnancy compared to preconception levels also had a lower risk of neonatal jaundice than those who decreased intake.

  • AOR 0.44 (95% CI: 0.24, 0.80), P < 0.007 for mothers who maintained probiotic intake
  • This was part of a stratification analysis on probiotic intake patterns
  • Both increasing and maintaining intake showed protective associations compared to decreasing intake

Neonatal jaundice is a prevalent global neonatal condition with long-term adverse effects on neurodevelopment and overall health.

  • NJ affects 60-80% of newborns globally
  • Current clinical treatments such as phototherapy primarily focus on symptom management
  • Preventive strategies for NJ remain largely lacking
  • NJ is characterized by significantly increased bilirubin levels
