Dietary quality influences body composition in overweight and obese pregnant women
<h4>BACKGROUND & AIMS: </h4><p>Excessive adiposity and gestational
weight gain (GWG) have been linked with maternal and offspring
morbidity. We investigated the relation of maternal diet, physical
activity and GWG ...
Gut Microbiota Richness and Composition and Dietary Intake of Overweight Pregnant Women Are Related to Serum Zonulin Concentration, a Marker for Intestinal Permeability
Background: Increased intestinal permeability may precede adverse metabolic conditions. The extent to which the composition of the gut microbiota and diet contribute to intestinal permeability during pregnancy is ...
Gut microbiota aberrations precede diagnosis of gestational diabetes mellitus

Body composition measurement by air displacement plethysmography in pregnancy: Comparison of predicted versus measured thoracic gas volume
<div><h3>Objectives</h3><p>Body
composition measurements with air displacement plethysmography (ADP)
define body volume, which must be corrected for thoracic gas volume
(TGV). We hypothesized that physiologic changes owing to pregnancy could
affect the accuracy of predicted TGV and introduce errors into body
composition measurements.</p></div><div><h3>Methods</h3><p>We
investigated the effect of measuring versus predicting TGV on the
accuracy of body composition calculations measured with ADP in
overweight and obese pregnant women. The fat and fat-free masses of 110
women were determined with ADP with predicted and measured TGV.</p></div><div><h3>Results</h3><p>Measured TGV decreased from early to late pregnancy (P = 0.0002).
Compared with measured TGV, predicted TGV was 6.3% higher during early
gestation and 12.6% higher during late gestation (both P ≤
0.001). The use of predicted instead of measured TGV in body composition
calculations resulted in an overestimation of fat mass by 0.8% during
the early stage, and 2.6% during the late stage of pregnancy (both P ≤ 0.001).</p></div><div><h3>Conclusions</h3><p>Measuring
TGV increases the accuracy of body composition measurement by ADP in
overweight and obese women, particularly during the late stage of
pregnancy.</p></div>...
