Abstract

BACKGROUND:
Rhinitis is one of the commonest occupational related respiratory disorders that is only restricted to the upper
airway but can involve the lower respiratory tract with considerable airflow limitation, this study was conducted
assess the ventilator function of persons exposed to saw dust with rhinitis symptoms
METHODS:
This is a cross sectional study carried out among 200 randomly selected saw mill workers and 200 healthy staff of
Jos University Teaching Hospital staff in Jos metropolis from September to November 2008. Data on
sociodemographic variables, symptoms of rhinitis, etc was obtained using a modified semi structured British
medical research council questionnaire while respiratory function data was measured using a spirometry
RESULT:
A total of 400 responds comprising of 200 saw mill workers and 200 controls participated in this study. Based on
diagnostic criteria. 43% of the subjects fit into diagnosis of rhinitis, 33% had asthma symptoms and 24 % did not fit
into any category compared to none of < 5% of the control group. The ventilatory function based on FEV1, FVC,
FEV1/FVC ratio and PEFR showed a significant decline when matched with controls and predicted value, suggesting
an airflow limitation among the rhinitis group.
CONCLUSION:
Rhinitis associated with wood dust exposure is not restricted to airway but involves the entire respiratory tract
with airflow limitation as one of its consequences.
