Comparative study of psychiatric morbidity among workers at a paint factory in Nigeria.

Inspite of numerous reports on the neurobehavioural effects of paints, there have been no such studies from Nigeria, where there are now many paint factories. The general aim of this study was, to assess the prevalence of specific psychiatric morbidity among workers in a large paint manufacturing factory. Using the Psychiatric Assessment Schedule (PAS), 60 workers (mean age, 38.1) directly involved in paint manufacture, 60 administrative staff (mean age 41.1) in the factory, and 60 postal workers (mean age 37.7) were assessed. Although higher proportions of factory workers (80%), and postal workers (73.3%) had positive PAS scores compared with administrators (36.7%), there were no significant differences in mean PAS scores across the groups. Two subjects each of factory workers (agoraphobia and dysthymia) and postal workers (dysthymia and generalised anxiety) fulfilled DSM-IIIR criteria for specific diagnosis. However, the paint workers had a wider spread of PAS symptoms, were significantly more likely to experience the symptoms constituting neurasthenia, had many more psychological complaints, experienced a wider variety of spontaneously reported symptoms, and constituted the most frequent users of health services. They had no knowledge of the possible mental health effects of exposure to paint. This level of distress is comparable to many reported findings.

Financial cost of treating out-patients with schizophrenia in Nigeria.

BACKGROUND: An assessment of the monetary costs of treating a group of Nigerian out-patients with schizophrenia, in comparison with insulin-dependent diabetics, was made. METHOD: Fifty out-patients with schizophrenia (mean age 42.9) and 40 with diabetes (mean age 41.9), attending government hospitals in Lagos, were assessed at six-monthly intervals, for direct and indirect costs (US$ = 82 naira; minimum monthly wage = 500 naira). RESULTS: Twenty (40%) of those with schizophrenia and eight (20%) of the diabetics had no income at all. The mean total cost of schizophrenia in six months (2941.4 naira) or US$ 35.9) was significantly less than that of diabetes (11,791 naira or US $143). The cost of antipsychotic drugs accounts for 52.8% of the cost of schizophrenia; insulin injections accounted for 92.8% of the total cost of diabetes. Patients with schizophrenia and their relatives suffered significantly more loss of working days. Cost of illness was not significantly correlated with age and duration of illness. CONCLUSIONS: Because of drastic currency devaluation, and lack of disability benefits and nursing homes, the findings contrast with Western reports where cost of drugs constitutes 2-5%, and indirect costs constitute over 50% of the total cost of schizophrenia.
