Abstract
BACKGROUND: Childhood depression is relatively common, under-researched and can impact social and cognitive function and self-esteem.
METHODS: Record linkage of routinely collected Scotland-wide administrative databases covering prescriptions [prescribing information system (PIS)], hospitalizations (Scottish Morbidity Records 01 and 04), maternity records (Scottish Morbidity Records 02), deaths (National Records of Scotland), annual pupil census, school absences/exclusions, special educational needs (Scottish Exchange of Educational Data; ScotXed), examinations (Scottish Qualifications Authority) and (un)employment (ScotXed) provided data on 766 237 children attending Scottish schools between 2009 and 2013 inclusively. We compared educational and health outcomes of children receiving antidepressant medication with their peers, adjusting for confounders (socio-demographic, maternity and comorbidity) and explored effect modifiers and mediators.
RESULTS: Compared with peers, children receiving antidepressants were more likely to be absent [adjusted incidence rate ratio (IRR) 1.90, 95% confidence interval (CI) 1.85-1.95] or excluded (adjusted IRR 1.48, 95% CI 1.29-1.69) from school, have special educational needs [adjusted odds ratio (OR) 1.77, 95% CI 1.65-1.90], have the lowest level of academic attainment (adjusted OR 3.00, 95% CI 2.51-3.58) and be unemployed after leaving school (adjusted OR 1.88, 95% CI 1.71-2.08). They had increased hospitalization [adjusted hazard ratio (HR) 2.07, 95% CI 1.98-2.18] and mortality (adjusted HR 2.73, 95% CI 1.73-4.29) over 5 years' follow-up. Higher absenteeism partially explained poorer attainment and unemployment. Treatment with antidepressants was less common among boys than girls (0.5% vs 1.0%) but the associations with special educational need and unemployment were stronger in boys.
CONCLUSIONS: Children receiving antidepressants fare worse than their peers across a wide range of education and health outcomes. Interventions to reduce absenteeism or mitigate its effects should be investigated.

Approvals
The authors applied for permission to access, link and analyse these data and undertook mandatory training in data protection, IT security and information governance. Therefore, the datasets generated and analysed during the study are not publicly available. The study was approved by the National Health Service Privacy Advisory Committee and covered by a data-processing agreement between Glasgow University and ISD, and a data-sharing agreement between Glasgow University and ScotXed. All data were linked by the Electronic Data Research and Innovation Service (eDRIS), part of NHS National Services Scotland.
Ethics
The NHS West of Scotland Research Ethics Service confirmed that formal NHS ethics approval was not required, since the study involved anonymized extracts of routinely collected data with an acceptably negligible risk of identification.
