title: Occupational health status of sawmill workers in Nigeria.
abstract: The health impact of exposure to sawdusts on 59 sawmill workers from southwest Nigeria was studied. Workers were chosen by a two-stage random sampling method from 15 privately owned sawmills. Peak flow and spirometric measurements were obtained from all workers. They also underwent a structured questionnaire which elicited occupationally related symptoms. Age and sex matched controls consisting of 199 workers from similar socio-economic backgrounds as the subjects underwent similar questionnaire and lung function tests. Results showed a high prevalence of respiratory symptoms, principally cough, chest pain and sputum production, among the workers. Most of the workers also had high prevalence of conjunctivitis, skin irritation and hearing difficulties when compared with controls. Pulmonary function parameters were also significantly lower (p < 0.05 in sawmill workers than controls). Although a large number (94.9%) of the workers were aware of the potential hazards of exposure to sawdusts, less than 20% wore protective masks. Our study highlights the need for health and safety regulation in the workplace. There is also a need for improved methods of dust control in factories with high levels of dust particulates, particularly in the developing world.
