Cancer risk among Danish male Seventh-Day Adventists and other temperance society members.
Cancer risk was studied in 781 male Seventh-Day Adventists (SDA) and 808 male members of other temperance societies. Standardized morbidity ratios for all cancers were 0.69 among SDA and 1.05 among other temperants. Significantly decreased risks of cancers were noted among SDA for cancer of the colon [observed/expected (O/E): 0.13], cancer of the respiratory system (O/E: 0.17), cancer of the lung (O/E: 0.15), and cancer of the bladder including papilloma (O/E: 0.13). No significant deviations from expectations were noted among members of other temperance societies. Thus risks of tobacco-associated cancers were markedly decreased among SDA. The risk of alcohol-associated cancers (cancers of the oral cavity, pharynx, esophagus, and larynx) taken together was also decreased (O/E: 0.7), although not significantly so. When the results were compared with those of a previous study of Danish brewery workers who had a high average daily beer intake, the present investigation provides further support that the alleged association between beer consumption and the occurrence of rectal cancer is of a noncausal nature. The explanation for the decreased risk of colon cancer should probably be sought in the dietary practices of SDA.
