Comparative study of lung functions in women working in different fibre industries.
A cross sectional work has been done on Bangladeshi females, working in different fibre industries, to study the effect of exposure to fibre dust on pulmonary functions. The ventilatory capacities were measured by VMI ventilometer in 653 apparently healthy women (160, 162 and 167 were jute, textile and garment industry workers, respectively). For the controls 164 females were recruited who never worked in any fibre industry. The observed FVC, FEV1 and PEFR were lower in all groups of fibre industry workers than those of the control. Among the industry workers, the jute mill workers had the lowest ventilatory capacities and garment industry workers had the highest values. The jute and textile mill workers had also significantly lower FEV1 and PEFR than those of garment industry workers. The FEV1 and PEFR were significantly lower in jute mill workers than those of textile ill workers. The low ventilatory capacities were almost proportionate with the length of service of the workers. Thus, the present study indicates that the fibre dust, on regular exposure for longer duration, may limit the lung functions.
