Lung function indices of flour millworkers in Edo and Delta States

Abstract

AIMS AND OBJECTIVES Flour dust has been associated with lung function impairment and Chronic Obstructive Airway Disease (COAD) among grain workers. This study was therefore conducted to assess the lung function indices of flour mill workers in Edo and Delta states, of Nigeria. MATERIALS AND METHODS Comparative cross-sectional study designed was utilized for the study and it was carried out over a period of six months, (Nov 2010 to May 2011) among 200 flour mill workers and 200 hospital workers in Edo and Delta states.A modified Medical Research Council (MRC) questionnaire which was interviewer administered and an electronic hand held spirometer was used to collect data. Data analysis was carried out using Statistical Package for Scientific Solution (SPSS) version 17. The Peak Expiratory Flow Rate (PEFR) of the flour dust exposed workers was significantly lower (p<0.001) compared to that of the unexposed population. All other lung function parameters were also lower although not statistically significant. Flour dust exposed workers in Edo Delta states like grain workers elsewhere have lung impairment, hence the need to provide protective equipment and also carry out regular periodic medical checks.
