Modzelewska D, et al. - The associations between prenatal caffeine exposure and neonatal health was determined via analyzing 67,569 full-term singleton mother-infant pairs from the Norwegian Mother and Child Cohort Study. Outcomes suggest an association of prenatal caffeine exposure with the child being born small for gestational age (SGA) and SGA with neonatal health, however, moderate prenatal caffeine exposure (< 200 mg/day) seemed not impairing neonatal health. According to the underlying cause of low birth weight, neonatal outcomes of SGA infants differed.
