The protocol was approved by the institutional review board at all 15 field centers. A sample for random plasma glucose RPG was collected at 34—37 weeks gestation as a safety measure to identify cases with hyperglycemia above a predefined threshold. Fetal insulin, stimulated by maternal glucose transport from mother to fetus across the placenta, may act on a variety of nutrients in addition to glucose, resulting in fetal overgrowth and adiposity.

New diagnostic criteria for gestational diabetes mellitus after the HAPO study. Prenatal care and timing of delivery were determined by standard field center practice. Gestational age and expected date of delivery EDD were determined from the date of the LMP, if the participant was certain of her dates.

In that case, if two of three measurements differed by less than the prespecified amount, the average of those two was used; otherwise the average of all three was used.

The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study.

Results of the study showing continuous relationships of maternal glucose levels below those diagnostic of diabetes with each of the primary outcomes have been reported 2.


Chronic hyperinsulinemia in the rhesus monkey disbetes Open in a separate window. Weaker associations were found with cesarean delivery and clinical neonatal hypoglycemia 2. Lowe, and Alan R. There were no significant nonlinear associations for glucose or significant interactions with field center, BMI, height, or MAP.

In fully adjusted continuous variable models, odds ratios ranged estuduo 1. Anthropometric estimation of neonatal body composition. Participants underwent a standard g OGTT between 24 and 32 weeks gestation as close to 28 weeks as possible.

Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study

With higher levels of cord C-peptide, frequency of each measure of size and adiposity rose. No haapo potential conflicts of interest relevant to this article were reported. For sum of skin folds, there was modest attenuation of the ORs with adjustment for model II confounders for all three glucose measures. Articles from Diabetes are provided here courtesy of American Diabetes Association. Glucose analysis and unblinding.

The findings reported here, however, are not proof of causality. Goals of this report are 1 to examine associations of maternal glycemia with newborn anthropometrics skin folds, percent body fat ; and 2 to present data linking fetal hyperinsulinemia assessed by cord serum C-peptide to the development of larger and more obese babies.

For both measures of neonatal adiposity, there was a strong graded association across increasing levels of maternal glycemia.

Please review our privacy policy. A training videotape providing instruction in anthropometric measurements was viewed. Journal List Diabetes v. No one glucose fiabetes was clearly superior to the others, suggesting that fluxes of maternal nutrients whether in the fasting or postprandial state are related to fetal growth.


CiteScore measures average citations received per document published.

Neonatal anthropometrics were obtained within 72 h of delivery. If uncertain, EDD was determined from an ultrasound performed between 6 and 24 weeks gestation. Notes Published ahead of print at http: Squared terms for age, BMI, and MAP were prescreened for possible inclusion in model II adjustment in models that included only linear and squared terms for these variables.

Furthermore, continuous relationships across the full range of maternal glycemia suggest that the Pedersen hypothesis is not limited to the high end of maternal glycemia but rather describes a basic biological relationship that influences maternal-fetal diabetse around fetal growth.

Research personnel observed measurements and then performed measurements on five infants.

To date, published studies of relationships between size at birth and risk of obesity in childhood and later life 14 are based primarily on birth weight for gestational age without information on degree of adiposity at birth.

Therefore, we elected to estimate body composition, in particular fat mass and percent body fat, as specific outcomes in the HAPO Study cohort. The finding of a continuous relationship between maternal glycemia and neonatal adiposity offers the potential to better understand, and possibly to influence, the development of obesity, a problem that is rapidly becoming epidemic diabetees the world Are you a health professional able to prescribe or dispense drugs?
