many Western youth, Chinese adolescents and young adults also have expressed
dissatisfaction with body size and shape (20-22).
Moreover, research has demonstrated that body image concerns were associated
with concerns about appearanceW1 IY2 , low self-esteem, depression, and stressful
in large samples of Chinese children and adolescents (10, 21, 23).
In extreme cases, such concerns can lead to eating disorders and even suicidal
ideation (9, 24).
In a population-representative study of Hong Kong adolescents, significant sex
differences in body size misperception were reported (25).
Girls were more likely to misperceive their body size than boys. Sex
differences in this characteristic have been reported among 9– to 10-year-old
children in Beijing (23).
becomes increasingly important to understand the extent of body image
misperception and the associations between it and unhealthy eating behaviors in
this population. However, few previous studies have tested the relationship
between weight misperception and eating behaviors. This study was therefore designed
to assess the associations between body weight misperception and unhealthy
eating behaviors among a cohort of Chinese adolescents.
