A cross-sectional study of work-related symptoms and cotton dust expos
ure was made in 404 man-made fiber and 1,048 cotton operatives in Lanc
ashire spinning mills; 39 cotton-exposed operatives (3.7%) had symptom
s of byssinosis. This was associated on regression analysis with cumul
ative lifetime cotton dust exposure (p < 0.001), total years spent car
ding (p < 0.001), and currently working in the carding area (p = 0.004
1). Smoking habit did not differ significantly between byssinotic and
nonbyssinotic workers. Other work-related symptoms were common: chroni
c bronchitis (CB) and persistent cough. The prevalence of CB correlate
d positively with dust exposure (r = 0.59). Cotton dust sampling was p
erformed in the work area (SDPRES) and personal breathing zone (PD1).
A retrospective estimate of lifetime cotton dust exposure based on SDP
RES correlated best with the prevalence of byssinosis (r = 0.797), alt
hough correlations with PD1 (r = 0.709) and SDPRES (r = 0.594) were al
so significant.
