Title Respiratory symptoms and chronic obstructive pulmonary disease among cement factory workers
Bibliographic information Aug. 2005, Vol.31, No.4, p.316-323. 37 ref.
Abstract This case-control study assessed chronic respiratory symptoms and chronic obstructive pulmonary disease (COPD) among workers exposed to cement dust at a Tanzanian cement factory. Subjects included 120 exposed workers and 107 controls. Information on demographics, occupational history, chronic respiratory symptoms, smoking habits and use of respiratory protection equipment was collected by questionnaire. Ventilatory function testing and measurement of personal total dust exposure were also carried out. Exposed workers had more chronic cough, chronic sputum production, dyspnoea, shortness of breath and chronic bronchitis than the controls. These symptoms were significantly related to cumulative dust exposure. The prevalence of COPD was higher for the exposed group (18.8%) than for the controls (4.8%). The odds ratio for COPD was significantly related to cumulative dust exposure.
