Ultrasound assessment of intrauterine growth restriction: relationship to neonatal body composition.

Objective: The objective of the study was to compare prenatal ultrasound parameters for intrauterine growth restriction (IUGR) with newborn percent body fat (%BF).

Study Design: This was a prospective study of 87 pregnancies followed with ultrasound. Subjects were categorized into 3 groups: estimated fetal weight (EFW) less than the 10th percentile, abdominal circumference (AC) less than the fifth percentile, and normal biometry.

Customized versus population-based growth curves: prediction of low body fat percent at term corrected gestational age following preterm birth.

Objective: Compare customized versus population-based growth curves for identification of small-for-gestational-age (SGA) and body fat percent (BF%) among preterm infants.

Methods: Prospective cohort study of 204 preterm infants classified as SGA or appropriate-for-gestational-age (AGA) by population-based and customized growth curves. BF% was determined by air-displacement plethysmography.

Complications of cesarean delivery in the massively obese parturient.

Objective: The objective of the study was to determine predictors of cesarean delivery morbidity associated with massive obesity.

Study Design: This was an institutional review board-approved retrospective study of massively obese women (body mass index, > or = 50 kg/m(2)) undergoing cesarean delivery. Bivariable and multivariable analyses were used to assess the strength of association between wound complication and various predictors.

Phosphatidylethanol and alcohol consumption in reproductive age women.

Background: Fetal alcohol disorders are preventable, but self-reported alcohol consumption can be misleading and impede effective treatment. Biomarkers represent an alternative method for assessing alcohol use, and this study evaluated the relationship between blood phosphatidylethanol (PEth) and alcohol use in a sample of reproductive age women.

Methods: Alcohol use was estimated by validated self-report methods in 80 nonpregnant women ages 18 to 35.
