Relationship of Fetal Macrosomia to Maternal Postprandial Glucose Control During Pregnancy

Abstract

OBJECTIVE: To determine the gestational ages at which maternal hyperglycemia is most closely related to fetal macrosomia; to determine whether macrosomia is related to elevations of fasting glucose, postprandial glucose, or both; and to assess the relationship of macrosomia to maternal insulin dose and caloric intake. RESEARCH DESIGN AND METHODS: One hundred eleven consecutive pregnant women with Class B through RF diabetes were studied longitudinally from 13 to 36 wk gestation. Macrosomia was defined by birthweight greater than 90th percentile for gestational age based on California norms. Women who delivered macrosomic infants were compared with those without macrosomic infants on pre- and postprandial blood glucose, GHb, insulin dose, macronutrient intake, and several other maternal variables. RESULTS: Macrosomia occurred in 32 (29%) cases, although several measures indicated reasonable glycemic control throughout pregnancy. Women delivering macrosomic infants did not differ from those without macrosomic infants in maternal age, prepregnant weight, duration of diabetes, White class, macronutrient intake, GHb, or fasting glucose. Macrosomia was associated with higher postprandial glucose levels up to 32 wk gestation and lower insulin doses from 29 to 36 wk gestation. In multiple logistic regression, macrosomia was significantly associated with postprandial glucose only between 29 and 32 wk gestation. Postprandial glucose values less than 7.3 mM (less than 130 mg/dl) were associated with a higher risk of small-for-gestational-age infants (18%) compared with values above this level (1%). CONCLUSIONS: Because macrosomia was related to postprandial glucose but not fasting glucose, we conclude that postprandial glucose measurement should be a part of routine care for diabetes in pregnancy. A target 1-h postprandial glucose value of 7.3 mM (130 mg/dl) may be the level that optimally reduces the incidence of macrosomia without increasing the incidence of small-for-gestational-age infants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
