title: Association of adolescents' weight status with life satisfaction: role of self, peers, family and school perception; the CASPIAN-IV Study.
abstract: BACKGROUND
  Although many public health programs have focused on prevention and control of obesity, their efficacy mostly depends on personal factors including perception of weight and personal understanding of the concept of being overweight. This study aims to investigate the association of adolescent's weight status with life satisfaction and explore the role of self, peers, family and school perception in this association.
  
  
  METHODS
  Data were obtained from the fourth school-based survey entitled "Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease" (CASPIAN) Study. This survey was conducted among 14,880 urban and rural students aged 6-18 years. Two sets of valid and reliable questionnaire obtained from Global School Health Survey (GSHS) were completed by students and their parents. The students' questionnaire had several questions including life satisfaction and the perception of weight, peers, family and school.
  
  
  RESULTS
  The study had a participation rate of 90.6% including 50.8% boys and 76% urban residents. Significant differences existed in Body Mass Index (BMI) and in perception of weight among girls and boys. Moreover, the prevalence of depression and being bullied were higher among girls and boys, respectively. Significant association was documented between life satisfaction and all variables including perception of weight, peers, family and school; the only exception was for BMI (P<0.05). In addition, students with normal weight had significantly higher life satisfaction in comparison with their obese counterparts (P<0.05).
  
  
  CONCLUSIONS
  The present study documented significant association between life satisfaction and perception of self, peer, family and school with the exception of BMI in both genders.
