Objective: To explore association between medically unexplained symptoms in children in Pakistan with emotional difficulties and functional impairments.
Methods: We conducted a matched three-group case-control study of 186 children aged 8-16 years in Lahore, Pakistan. Cases were 62 children with chronic somatic symptoms for which no organic cause was identified after investigations. Two control groups of 62 children with chronic medical paediatric conditions, and 62 healthy children were identified. Cases and controls were matched for gender, age, and school class. Somatisation was measured with the Children's Somatisation Inventory (CSI-24) while anxiety and depression were measured with the Spencer Children's Anxiety Scale and the Short Mood and Feelings Questionnaire respectively. All questionnaires were translated into Urdu.
Results: Mean age was 11.7 years (SD=2.1). Cases scored significantly higher on somatisation (CSI-24), anxiety and depression than both control groups. Paediatric controls scored significantly higher than healthy controls on all three measures. Two hierarchical linear regression models were used to explore if somatisation predicted depression and anxiety while controlling for several confounders. Somatisation (higher CSI-24 scores) independently and significantly predicted higher anxiety (β=.37, p=.0001) and depression (β=.41, p=.0001) scores.
Conclusion: This is the first study to show an association between medically unexplained symptoms and anxiety and depression in Pakistani children. This highlights the importance of screening for emotional difficulties in children presenting with unexplained somatic symptoms in this region.
