Maternal obesity and sex-specific differences in placental pathology.

Objective: Adverse effects of obesity have been linked to inflammation in various tissues, but studies on placental inflammation and obesity have demonstrated conflicting findings. We sought to investigate the influence of pregravid obesity and fetal sex on placental histopathology while controlling for diabetes and hypertension.

Methods: Placental histopathology focusing on inflammatory markers of a cohort of normal weight (BMI = 20-24.
