Sickness absence, respiratory impairment and smoking in industry: an australian study

Med J Aust. 1981 Mar 7;1(5):235-7.


A retrospective study of sickness absence, respiratory impairment and their relation to smoking habits was conducted among a heterogeneous population of 1867 staff members of 12 Australian organizations. Data on smoking habits were used to divide the sample into current cigarette smokers (n=392), ex-cigarette smokers (n=182) and those who had never smoked (n=714). Results of the health survey by self-administered questionnaire showed that the prevalence of respiratory symptoms was higher in cigarette smokers than in non-smokers both in men and women. Smoking was particularly related to frequency of cough, and sputum production. Wheezing showed a similar, though less marked, trend. The influence of smoking on the pulmonary function value, FEV1/FVC% was assessed in a group of 972 men and 297 women. Results of analysis of variance showed that ventilatory function was significantly impaired among smokers and ex-smokers. The sickness absence records of 826 cigarette smokers, ex-smokers and non-smokers were also compared. Both frequency and duration of sickness absence were greater in cigarette smokers and ex-smokers. Significant differences between these groups were confirmed in total as well as in certified absence. Among males, the average number of days off work was 1.59 times greater in male smokers than in male non-smokers, and 1.36 times greater for female subjects who smoked. The epidemiological implications of such findings await further research. However, the consequences for the individual, industry and the general community are apparent.
