RESUMEN
Multiple logistic regression model was used considering byssinosis as an independent variable, and dustiness, smoking, exposure years and age as explanatory variables. Dustiness and length of exposure to the dust were found to be the most important contributory factors to byssinosis prevalence. The risk of byssinosis among workers in card room, blow room and waste plant sections and those who had exposure of more than 5 years was nearly three times than that among workers of other sections of the mill and/or with less than 5 years of exposure.

Lung function was studied by forced expiratory spirograms and measurement of peak expiratory flow in fourteen young male subjects of the age 20 to 30 years. Seven of the subjects were cotton spinners in small shops in Paharganj market with the duration of work from 1 to 3 years. The other seven subjects served as controls. All the subjects were of the same socio-economic status and were North Indians. Forced vital capacity; forced expiratory volume in 1 sec; forced expiratory volume in 1 sec expressed as a percentage of forced vital capacity; forced expiratory flow between 80 and 70 per cent, between 55 and 45 per cent, between 30 and 20 per cent and between 15 and 5 per cent of the forced vital capacity were determined from forced expiratory spirograms. Peak expiratory flow and FEB-80-70% were significantly lower in cotton spinners suggesting involvement of larger airways.
