Newborn Adipokines and Birth Outcomes

Area of Science:

• Endocrinology
• Neonatal Research
• Public Health

Background:

• Adipokines, signaling molecules from adipose tissue, are indicators of metabolic status.
• Previous studies on cord blood adipokines and birth outcomes have yielded conflicting results.
• Newborn dried blood spots (DBS) offer a valuable resource for assessing neonatal adipokine levels.

Purpose of the Study:

• To investigate the cross-sectional associations between adipokines measured in newborn DBS and key birth outcomes.
• To determine if adipokine levels in newborns predict risks of preterm delivery and small-for-gestational age (SGA).

Main Methods:

• Utilized data from the Upstate KIDS study (2008-2010) including 2397 singletons and 1240 twins.
• Measured adipokines in residual newborn DBS using Luminex technology (Human Obesity Panel).
• Employed multivariable logistic regression and generalized estimating equations to analyze associations between adipokine quintiles and birth outcomes (preterm birth, SGA).

Main Results:

• Lower adiponectin levels in newborns were significantly associated with increased odds of preterm birth and SGA in both singletons and twins.
• Resistin showed an association with preterm birth in singletons but not twins.
• Adipsin exhibited inconsistent associations with birth outcomes after statistical adjustments.

Conclusions:

• Newborn DBS-measured adipokines are demonstrably associated with birth outcomes.
• Lower adiponectin levels are a significant predictor of preterm birth and SGA, irrespective of whether the infant is a singleton or a twin.
• Adipokines measured in newborn DBS represent potential biomarkers for identifying infants at risk for adverse birth outcomes.
