Pathways of parental influence on adolescent diet and obesity: a psychological stress–focused perspective

Youth obesity has become increasingly prevalent, with 34.5% of US adolescents 12-19 years old estimated to have overweight or obesity. Disordered eating and weight concern peak in adolescence, and overeating to cope with negative emotions can affect long-term health and obesity risk. Parents significantly influence adolescent diet quality, and parental stress may influence parenting behaviors that increase the risk for stress-motivated eating and obesity in adolescents. Chronic or repeated exposure to parental stress may lead to stress-related neurophysiological changes that promote consumption of palatable foods and obesogenic eating habits in adolescents. Understanding how parental stress influences adolescents' eating behavior may reveal novel access points for reducing adolescent obesity. Here, we aim to provide a new stress-focused framework for developing intervention strategies targeted at obesity prevention in adolescents.
