The aim of this study was to assess the prevalence of respiratory health problems, lung
function and correlates among rice mill workers.
Materials and Methods
A cross sectional study was carried out among 150 workers consecutively recruited at the
Abakaliki Rice Mill industry, Nigeria. Lung functions were measured using spirometer. Data
were analysed using Epi-Info version 3.5.3.
The commonest respiratory symptoms among rice mill workers were rhinitis 65 (43.3%) and
blocked nostrils 62 (41.3%). Less than half of the participants 61 (40.7%) had abnormal lung
function pattern, 45 (30.0%) had a restrictive lung function pattern, 13 (8.7%) had obstructive
lung pattern and only 3 (2.0%) had a combined lung pattern.
There is a high prevalence of respiratory symptoms and abnormal lung function patterns,
mostly restrictive. There is need for education on dust control and enforcement on use of
personal protective equipment among rice mill workers.
