Psychiatric disorders in children attending a Nigerian primary care unit: functional impairment and risk factors

Abstract

BackgroundThere is dearth of data on the level of functional impairment and risk factors for psychiatric morbidity in children attending primary care services in developing countries like Nigeria. The risk factors for psychiatric morbidity and functional impairment in children attending the primary care unit of a teaching hospital in Ilorin, Nigeria was therefore investigated to obtain data that could be used in improving service provision by primary care physicians.MethodsA cross-sectional two-stage design was employed for the study. The first stage involved administration of the Child Behavior Questionnaire (CBQ) to 350 children while the children’s version of the schedule for affective disorders and schizophrenia was used for the second stage involving 157 children, all high scorers on CBQ (score of ≥ 7) and 30% of low scorers (score < 7). Diagnosis of psychiatric disorders was based on DSM-IV criteria.In addition, the Children Global Assessment Scale was used to assess the functional status of the children (score of ≤ 70 indicates functional impairment) while the mothers’ mental health status was assessed with the 12-item version of the General Health Questionnaire, a score of 3 or more on this instrument indicate presence of mental morbidity.ResultsIt was observed that 11.4% of the children had diagnosable psychiatric disorders and 7.1% were functionally impaired; and those with psychiatric disorders were more functionally impaired than those without. Thus, significant negative correlation was noted between CBQ scores and CGAS (r = 0.53; p < 0.001). Following logistic regression, younger age of children, frequent hospital attendance and maternal parenting distress independently predicted psychiatric morbidity while child psychopathology and maternal parenting distress predicted functional impairment.ConclusionsChild psychiatric disorders are prevalent in the primary care unit studied. Many of the risk factors identified in the study population are modifiable. Collaborative efforts between psychiatrists and primary care physicians could therefore help to reduce level of risk and functional impairment and psychiatric morbidity among children attending the primary care unit studied. It could also help improve referral rates of difficult cases to the child and adolescent psychiatric unit of the hospital.
