||Asbestos-related disease in public school custodians
||Mar. 1991, Vol.19, No.3, p.303-316. Illus. 41 ref.
||A cross-sectional prevalence study of 120 public school custodians was carried out. The purposes were 1) to investigate the prevalence of asbestos-related disease in a group of custodians at risk for asbestos exposure in public schools and 2) to determine the proportion with disease attributable to exposures in school buildings. Medical and occupational histories, flow-volume loops, and posterior-anterior, lateral, and anterior oblique (AO) chest radiographs were obtained. Mean age of subjects was 57 years and mean duration of work as a custodian, 27 years. Fifty-seven (47.5%) had no known or likely exposure to asbestos outside of their work as a school custodian (NOE). Pleural plaques (PP) occurred in 40 (33%) of the total group and 12 (21%) of the group with NOE. Pulmonary restriction (FVC < 80% predicted, FEV1/FEV% ≥70) occurred in 22 (18%) of the total group and 10 (17%) of those with NOE. Multivariate analysis revealed significant associations (p<0.05) between both PP and restriction and duration of asbestos exposure. AO radiographs increased PP detection by a factor of 1.9. The results revealed PP prevalence in excess of background an pulmonary restriction in the study population, and indicated that PP were attributable to asbestos in schools. Prudent management of asbestos in buildings is indicated for the prevention of related disease.
