Is Meal Frequency Associated with Mental Distress and Violent Behaviors in Children and Adolescents? the CASPIAN IV Study

Abstract

<strong><em>Background</em></strong><strong>: </strong>This study aimed to assess the relationship between meal frequency with mental distress and violent behavior among a nationally representative sample of Iranian children and adolescents. <br/><strong><em>Materials and Methods</em></strong><strong>: </strong>The participants of this national study were 14,880 Iranian students with 6 to 18 years of age. They were selected from urban and rural regions of Iran by multi-stage cluster sampling method. The data were obtained about demographic information, mental distress, violent behaviors and meal frequency by the questionnaire of the World Health Organization-Global School-based Student Health Survey (WHO-GSHS). <br/><strong><em>Results</em></strong><strong>: </strong>The response rate was 90.6%. The participants who were categorized as the group eating 3 meals per week significantly experienced less mental distress than those who were categorized as consuming 2 meals and one/no meal per week (P-value < 0.05). The min rate of violent behaviors was observed among participants who were classified as consuming 3 meals group and the max rate in one/no meal group. Participants who were categorized as consuming one/ no meal and 2 meals per week had higher risk of mental distress and violent behaviors compared with those whom consumed 3 meals per week. <br/><strong><em>Conclusions</em></strong><strong>:</strong> Meal skipping was significantly associated with mental problems and violent behaviors among Iranian children and adolescents and this association was independent of known confounders.
