Abstract: | BACKGROUND/AIM: Results of epidemiological studies concerning the association between smoking and alcohol use and gallstone risk are inconsistent. We examined the relation of smoking and alcohol use to gallstone disease in Japanese men. METHODS: We investigated 174 cases having gallstones as determined by ultrasonography, 104 cases of postcholecystectomy state, and 6,906 controls having a normal gallbladder in the consecutive series of 7,637 men aged 48-59 years receiving a retirement health examination at four hospitals of the Self-Defense Forces from 1986 to 1994. Fifty men had been aware of having gallstones. Known gallstones and postcholecystectomy state were combined as known gallstone disease. Smoking and drinking habits were ascertained by a self-administered questionnaire. Statistical adjustment was made for body mass index, glucose tolerance status, Self-Defense Forces rank, hospital, and either cigarette smoking or alcohol use. RESULTS: Cigarette smoking was not measurably associated with either prevalent gallstones or postcholecystectomy state, nor with either newly diagnosed gallstones or known gallstone disease. Alcohol use was related to a significant decrease in the prevalence odds of both gallstones and postcholecystectomy state, and the decrease was slightly more profound for known gallstone disease. CONCLUSIONS: Cigarette smoking is probably unrelated to the gallstone risk, and alcohol consumption seems to confer protection against gallstone formation. |
