Goldschmidt AB, et al. - Physicians designed this study to identify weight-change trajectories and their concomitant associations with prospectively measured dieting and other disordered eating behaviors among initially nonoverweight adolescents during the transition to adulthood. Results suggested that healthy lifestyle interventions could benefit individuals who were probably perceived as a low risk for overweight in adulthood by nature of being nonoverweight in adolescence. However, adolescents who were already overweight were most frequently targeted for weight-gain prevention and early intervention programs. Dieting and unhealthy weight-control behaviors tended to be correlated with weight gain, implying that they were ineffective in addition to being potentially harmful.
