Trajectories of Body Dissatisfaction and Dietary Restriction in Early Adolescent Girls: A Latent Class Growth Analysis.

Clarifying the trajectories of body image and eating concerns in adolescents is critical. We examined longitudinal patterns of development of body dissatisfaction and dietary restriction among early adolescent girls within a sociocultural framework. A sample of 259 school girls (M age = 12.76 years, SD = 0.44) reported on sociocultural influences, body dissatisfaction and dietary restriction at baseline, 8, and 14 months. A subsample provided height and weight. Analyses identified four trajectories of body dissatisfaction: low, moderate-increasing, moderate-decreasing, and high. Three trajectories of dietary restriction emerged: low, moderate, and high. Baseline and 8-month sociocultural variables and BMI differed between the trajectories. A subgroup of girls displays high levels of body image and eating concerns by early adolescence. Sociocultural variables influence these trajectories.
