Abstract
Glycosylated hemoglobin levels were measured and studied in 92 uneventful full-term pregnancies at 6–8 weeks postpartum. There was a significant positive correlation between the glycosylated hemoglobin levels and the concomitant hemoglobin levels (p < 0.05) unrelated to birth weight (r = –0.032). Birth weight had a significant positive correlation with the maternal body mass index (p < 0.01) and a negative correlation with maternal third-trimester hemoglobin levels (p < 0.01). Hemoglobin levels during the third trimester reflect in part physiological hemodilution related to the function of the fetoplacental unit. It is suggested that high hemoglobin levels during the third trimester may identify healthy women with a small fetus for the gestational date.
