Background: No previous epidemiological studies of child mental health have been conducted in Bangladesh, partly due to lack of suitable measures.
Methods: A Bangla translation of a standardised child psychiatric interview, the Development and Well-Being Assessment (DAWBA), was validated against routine clinical diagnoses on a consecutive series of 100 referrals to a child mental health service. A two-phase study of prevalence was applied to random samples of 5- to 10-year-olds (N=922) drawn from three contrasting areas: a rural area, a moderately prosperous urban area, and an urban slum.
Results: There was substantial agreement between the DAWBA and the independent clinic diagnosis (kappa=0.63-0.94). The estimated prevalence of any ICD-10 diagnosis was 15% (95% CI 11-21%). The rate of obsessive-compulsive disorder was higher than in previous studies. Children from the slum area were significantly more likely to have serious behavioural problems, and marginally more likely to have post-traumatic stress disorder.
Conclusion: A conservative extrapolation is that around 5 million Bangladeshi children and adolescents have psychiatric disorders. In a country with very few child mental health professionals, there is a vast gap between need and provision that must be addressed.
