Rapid increases in BMI waist to height ratio during adolescence and subsequent neurobehavioral deficits

A new study reveals concerning links between adolescent weight gain and neurobehavioral development. Researchers found that between ages 11 to 15, 10.7% to 13.0% of adolescents experienced overall obesity, with 13.0% to 19.8% facing abdominal obesity. Those with rapidly increasing BMI z scores were more likely to exhibit delinquent and aggressive behavior and externalizing problems. Similarly, a rapidly increasing waist-to-height ratio (WHtR) predicted higher social problems and delinquency risks. These associations were more pronounced in girls, underscoring the importance of timely weight management interventions for promoting adolescent mental health.
