title: Is breakfast consumption related to mental distress and academic performance in adolescents?
abstract: OBJECTIVE
  To examine the relationship between mental distress, academic performance and regular breakfast consumption across gender and immigration status.
  
  
  METHODS
  Cross-sectional population-based study. Two four-page questionnaires were filled in during two school sessions.
  
  
  METHODS
  All junior high schools in Oslo, Norway using the classroom as the setting for the study.
  
  
  METHODS
  All 10th grade students 15-16 years olds in 2000 and 2001. Of 8316 eligible students, 7343 (88.3%) participated in the study.
  
  
  RESULTS
  All immigrant groups, except the Western countries group, are skipping breakfast more often than Norwegian students, and girls more often than boys (27 versus 19%). After adjustment for possible confounding factors, the odds ratio (OR) for being mentally distressed when eating breakfast seldom/never compared with every day was 3.0 (2.0-4.5) for boys, 1.6 (1.2-2.1) for girls and 1.6 (1.5-2.6) for the immigrant group. The comparable OR for having low school grades was similar for boys and girls, 2.0 (1.3-3.0), and 1.6 (1.5-2.6) for the immigrant groups.
  
  
  CONCLUSIONS
  Skipping breakfast is a common feature among 10th grade students. The implications of skipping breakfast on mental distress and academic performance are stronger for boys than girls and stronger for Norwegians compared with immigrants.
