Today’s obese children aren’t just carrying around extra weight. According to researchers from Erasmus Medical Clinic, at Sophia Children’s Hospital in Rotterdam, The Netherlands, they are also carrying higher levels of the stress hormone cortisol.
The study observed 20 obese and 20 normal-weight children aged 8–12. To determine cortisol levels, researchers took scalp hair samples from each subject. Data showed that obese children had higher levels of hair cortisol than normal-weight children.
