Small but statistically significant excesses of colon cancer were observed among white-collar occupations, including administrators, professionals, and clerical and sales workers, whereas a reduction in incidence was found among workers in agricultural and related jobs, such as farmers, fishermen, and hunters. Analysis by subsite within the colon revealed little difference in results. The observed risk patterns are consistent with previous reports on colon cancer risk and occupational physical activity levels, ie, elevated risk among sedentary white-collar workers and reduced risk among agricultural workers. Few craftsman and production processing jobs were linked to colon cancer, although statistically significant excesses were observed among shoe and leather workers, metal smiths, and foundry workers in the metal manufacturing industry. The findings indicate that occupation in general is likely to play a relatively small role in colon cancer etiology, with perhaps its major contribution an indirect one via physical activity.</p>","PeriodicalId":16617,"journal":{"name":"Journal of occupational medicine. : official publication of the Industrial Medical Association","volume":"36 6","pages":"647-51"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19065151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary function test (PFT) measurements included a minimum of three readings of forced expiratory volume at 1 second (FEV1). A \"reliable\" test was one where the two best volumes were within 5%. Medical history and respiratory symptoms were assessed on a standardized questionnaire. Fifty-nine of the 864 tested were unable to reproduce their best FEV1 result. Although these 59 case subjects had significantly lower PFT results than the other 805 tested (P < .01), the mean values for FEV1 and forced vital capacity for the case subjects were greater than 90% of predicted values. The case subjects were more likely to experience wheezing and dyspnea and have a history of emphysema than the rest of the group screened (n = 805). They also had a higher mean age and more years in the trade. Twenty-one of the 59 case subjects were among the 602 who participated in a similar health screening program offered 3 years later. To minimize the effects of age and smoking status on PFT performance, these 21 case subjects were each matched on age and smoking with two comparison subjects who had reliable tests. At follow-up, the 21 case subjects and 41 comparison subjects both had a decline in ventilatory capacity that was significantly greater than would be expected by advancing age alone.

The study cohort comprised 412 male workers with at least 6 months employment and 10 years latency. For the extended follow-up period (October 1985 to May 1992), the standardized incidence ratio (SIR) based on state comparison rates was slightly elevated and not statistically significant (SIR = 1.5, 95% confidence interval [CI] = 0.5 to 3.5). A 2.3-fold excess was observed among process workers (95% CI = 0.3 to 8.2), but this was based on only two cases. Risk among process/mechanical workers was greater for short-term workers (< 10 years, SIR = 3.2, 95% CI = 0.7 to 9.2) compared with longer-term workers (> or = 10 years, SIR = 0.7, 95% CI = 0.02 to 4.0).

They were followed up and interviewed again in 1985 and 1990. First, the results showed that nurses had more sleep disorders on alternating schedule including night work at the beginning of the study in 1980, and there was no more association between shift work and sleep quality after 1980. Second, sleep disorders predicted transfer from shift work to day work between 1980 and 1985 and sleep disorders decreased strongly after such transfer.
