Obesity Linked to Abnormalities in Brain Structure, Study Says

Obesity is associated with brain structural abnormalities in healthy individuals, as well as in those with major depressive disorder (MDD), a study has found. The findings revealed that carrying a higher genetic risk for obesity is linked with reduced brain surface area. The study, “Brain Structural…

BMI and Obesity-related Traits Strongly Affected by Genetic-Environmental Interactions, Study Asserts

Unlike height, body mass index (BMI) and other obesity-related traits are strongly influenced by interactions between an individual’s genetic background and environmental factors. A study with that finding, “Genotype-by-environment interactions inferred from genetic effects on phenotypic variability in the UK Biobank,” was published in Science Advances. “Most…

Gene Variants Linked to Risk of Excessive Weight Gain During Pregnancy

Scientists discovered gene variants that increase the risk of excessive weight gain in women during pregnancy, which is directly associated with excessive weight in newborns. The findings of the study, “MC4R and ENPP1 gene polymorphisms and their implication in maternal and neonatal risk for obesity,” were published in…
