Abstract
INTRODUCTION: The maternal glycosylated hemoglobin (HbA1C) level in early pregnancy has been observed to be lower than the prepregnant value. In Japan, the average body mass index (BMI) shows a very slight change during early pregnancy, which has been thought to be associated with the incidence of hyperemesis gravidarum. METHODS: We examined the relation between HbA1C and changes in BMI levels of 274 pregnant Japanese women managed at our hospital during early pregnancy. RESULTS: The average HbA1C in early pregnancy was 5.1 +/- 0.4%, which did not differ markedly from that of nonpregnancy (5.0 +/- 0.5%). The HbA1C level showed a negative correlation with the increasing value of BMI during early pregnancy (r2 = 0.26, p < 0.05). CONCLUSIONS: In this study, we could not identify a significant decrease in HbA1C in Japanese women during early pregnancy. This finding may be associated with the incidence of hyperemesis gravidarum in Japanese women.
