A significant negative correlation observed between BMI z-score (R -.41; .007), -0.32; .039). Conclusion suggests who are eat at period counterparts This unexpected finding based on objective data appears conflict existing questionnaire findings but provides impetus further work testing effectiveness changing eating behaviour weight-management intervention youth.
