There is substantial literature showing that birth weight is associated with differences in blood pressure within the reference range. These differences are found in children and adults, but they tend to be small. A 1-kg increase in birth weight is associated with 3 mm Hg lowering in systolic pressure.

The authors examined the association of serum perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) with self-reported pregnancy outcome in Mid-Ohio Valley residents (2000-2006) highly exposed to PFOA. Data on 1,845 pregnancies within the 5 years preceding exposure measurement were analyzed for PFOA, and data on 5,262 pregnancies were analyzed for PFOS. Generalized estimating equat...

OBJECTIVE The construction of a predictive model that improves the estimation of the fetal weight (EFW). STUDY DESIGN a comparative, descriptive study. One hundred forty pregnant women were recruited at two-stage sample in health department in Spain. They were classified in four groups depending on the pre-gestational BMI. Fetal weight at term was estimated by ultrasound at 33-35 weeks (EFW40...
