Objective: To determine the association between maternal obesity and fetal glycated albumin (GA) levels among pregnant women.
Methods: A comparative, cross-sectional study of 59 consenting, normoglycemic, pregnant women, who met the criteria for maternal obesity, attending the antenatal clinic of the University College Hospital, Nigeria, from June 2019 to December 2019. They were recruited at 36 weeks of gestation, followed up until delivery, and compared with 58 nonobese, normoglycemic pregnant controls. At delivery, blood samples were taken from the mothers and from the umbilical cords of their newborns for serum GA assay. Maternal and newborn variables were recorded, and comparisons were made using χ2 tests, independent t tests, odds ratios, analysis of variance, and Pearson correlates. Statistical significance was set at P < 0.05.
Results: The odds of elevated newborn GA were 3.21 times higher in obese women compared with nonobese women (P = 0.005) and 5-min APGAR scores were higher in the newborns of nonobese women (P = 0.039). There was a significant correlation between maternal and neonatal GA for all participants (r = 0.346, P = 0.000).
Conclusion: These findings suggest that maternal obesity is associated with elevated fetal GA and low APGAR scores at 5 min in normoglycemic women.
