PENN STATE / JOHNS HOPKINS (US) — Children who overreact to stressful situations will eat even if they’re not hungry, raising their risk of becoming overweight or obese, a new study shows.“Our results suggest that some children who are at risk of becoming obese can be identified by their biological response to a stressor,” says Lori Francis, associate professor of biobehavioral health at Penn State. “Ultimately, the goal is to help children manage stress in ways that promote health and reduce the risks associated with an over- or under-reactive stress response.”
