摘要

Cotton dust, when breathed in, irritates the lungs and exposed workers experience the following symptoms: difficulty in breathing, chest tightness, coughing and wheezing. The current analysis was limited to the objective of determining the proportion of workers experiencing difficulty in breathing, chest tightness, coughing, wheezing and phlegm. A cross sectional study was conducted among workers in a cotton spinning mill. A convenient sample was selected by the management from all work-areas. A structured questionnaire enquiring about the respiratory health was administered to the employees. A total of 297 employees took part in the study of whom 274 (92.3%) were males. The median age (Q1, Q3) for males [29 (26, 34)] was significantly greater (p<0.001) than that for females [24 (23, 28)]. The majority of the workers had been in employment for less than one year (46.1%). Fifty (16.8%) of the 297 workers smoked cigarettes (all the 23 females were non-smokers). Wheezing was recorded in 4.4% of the workers, chest tightness (14.5%), cough (19.9%), phlegm (11.4%) and breathlessness (5.7%).The observed generally low rates of respiratory conditions may have been partly due to underreporting and partly due to sampling bias. An annual medical check-up is recommended for all employees.
