This nine-month prospective study tested the extent to which risk factors implicated in recent accounts of body dissatisfaction predicted changes in body image concerns of adolescent boys and girls in China. A sample of 593 Chinese adolescents (217 boys, 376 girls) completed measures of weight esteem, appearance esteem and physical stature concern in addition to demographics, internalization of attractiveness ideals, negative affect, and appearance pressure, teasing, and comparison at baseline and nine-month follow-up. For girls, initial levels of social comparison, and internalized attractiveness ideals predicted decreases in body esteem over time. Time 1 negative affect contributed to changes in both appearance esteem and weight esteem for boys. Baseline level of stature concerns and reported height were the only predictors of later stature concerns within each sex. In sum, this study suggests specific factors previously implicated in Western accounts also have utility for understanding body image concerns of adolescents in China. (Contains 7 tables.)
