Obesity in expectant mothers was linked to poor blood vessel development and fetal oxygen deprivation in a study of obese rats fed a high-fat diet from birth, according to a study in PLoS ONE. Maternal obesity is linked to higher risk of miscarriage, stillbirth, under- or overweight babies, and children with type 2 diabetes, cardiovascular disease and spina bifida. The findings may aid in drug development meant to improve health outcomes in obese mothers, researchers said.
