back Weight perceptions, academic performance, and psychological factors in Chinese adolescents. B. Xie Objective: To investigate weight perception and related psychological factors in Chinese adolescents. Methods: 6863 middle and high school students completed a questionnaire on weight perception, academic performance, stress, hostility, and depression. Weight and height were measured. Results: Overweight perception was related to school-related stress and depression in both girls and boys (P<0.01) and to hostility in boys (P<0.01). Perceived overweight was related to lower GPA in girls only (P<0.05). Conclusions: Distorted weight perception has a detrimental psychological impact on Chinese adolescents. These findings may contribute to the obesity research and to the development of future effective intervention programs in China.
