Assessment of pulmonary function among cleaners in governmental hospitals in Addis Ababa, Ethiopia; comparative cross-sectional study

Abstract

Abstract Objective Work-related disorders are the major causes of different diseases in working populations. Respiratory disorders are among the most common occupational diseases. The alterations of the pulmonary function of professional cleaners in hospitals have not been addressed previously in Ethiopia. The aim of this study was to assess the pulmonary functions of cleaners working in the hospital setting in Addis Ababa, Ethiopia. A comparative cross-sectional study design was employed. The study was composed of 70 cleaners and 70 control subjects. Spirometer was used to measure pulmonary function. The data were coded, entered and analyzed using SPSS version 20. Results The mean and standard deviation of both actual value and percent predicted for forced vital capacity, forced expiratory volume in 1 s, percent ratio of forced vital capacity and forced expiratory volume in 1 s, peak expiratory flow rate and forced expiratory flow between 25 and 75% of cleaners were found to be significantly lower than the control group. Among cleaners 24.3% (n = 17) and controls 8.6% (n = 6) had shown obstructive lung disease, and among cleaners 22.9% (n = 16) and controls 4.3% (n = 3) had shown restrictive pattern.
