Abstract:
OBJECTIVETo study the association between maternal pre-pregnancy body mass index (BMI) and adverse outcomes of late preterm infants (LPI).
METHODSA total of 367 LPI who were born from January 2011 to December 2015 and admitted to the neonatal ward were enrolled. The BMI criteria for Chinese population were used to analyze the factors for maternal pre-pregnancy BMI and its association with adverse outcomes of LPI (1 minute Apgar score ≤7, delivery room resuscitation, hospitalization days after birth >7 days, and ventilation duration ≥6 hours).
RESULTSOf all LPIs, there were 64 LPI (17.4%) in the low maternal pre-pregnancy BMI group, 243 LPI (66.2%) in the normal maternal pre-pregnancy BMI group, and 60 LPI (16.4%) in the high maternal pre-pregnancy BMI group. Low pre-pregnancy BMI was the risk factor for 1 minute Apgar score ≤7 (OR=3.243, 95% CI: 1.102-9.546) and need for delivery room resuscitation (OR=3.492, 95%CI: 1.090-11.190), and high pre-pregnancy BMI was the risk factor for hospitalization days after birth >7 days (OR=1.992, 95%CI: 1.024-3.874).
CONCLUSIONSAbnormal maternal pre-pregnancy BMI has adverse effects on the outcomes of LPI. In order to reduce these adverse outcomes BMI should be controlled within the normal range in pregnant women.
