28 Nov 2022 --- A study using data from long-term research on brain development shows that higher body mass index is associated with poor brain health in children, based on MRI scans. The Centers for Disease Control and Prevention stresses that one in five American children is obese. “Increased BMI and weight are not only associated with physical health consequences but also with brain health,” says Simone Kaltenhauser, researcher and a post-graduate research fellow in radiology and biomedical imaging at the Yale School of Medicine in New Haven, Connecticut.
