title: Disordered eating attitudes and behaviours among adolescents in Hong Kong: prevalence and correlates.
abstract: OBJECTIVE
  To study the prevalence of disordered eating attitudes and behaviours among adolescents in Hong Kong and to examine the socio-demographic and behavioural correlates.
  
  
  METHODS
  Three secondary schools with different academic performance were selected from the Eastern District of Hong Kong. A total of 2382 students enrolled in Forms 1-7 at the three schools completed a specially designed questionnaire. The questionnaire contained questions on socio-demographic information, body weight satisfaction, exposure to mass media, health behaviours as well as the Eating Attitudes Test - 26 (EAT-26). Data were analysed using Student's t-test, chi2 analysis and multivariate logistic regression models.
  
  
  RESULTS
  Disordered eating (EAT score > or =20) was present in 52 (3.9%) adolescent boys and 68 (6.5%) adolescent girls. The youngest case was only 11 years old. A high degree of body weight dissatisfaction was shared by our adolescents. Teenage girls, overweight youths and those with poor academic performance were at increased risk of having disordered eating. Strong associations were found between disordered eating and other health-compromising behaviours including smoking, alcohol and soft drug use, delinquent behaviours, suicidal ideation and self-harm behaviours. Exposure to entertainment, beauty and youth magazines was positively related to disordered eating.
  
  
  CONCLUSIONS
  Disordered eating is prevalent among adolescents in Hong Kong. It remains a significant public health challenge to our community. Prevention programmes targeting youths at the greatest risk should be considered.
