Association between smoking, acetaldehyde dehydrogenase-2 1-1 status, and alcohol drinking among Taiwanese polyvinyl chloride workers.
To study the factors affecting alcohol consumption among Taiwanese workers, we conducted an investigation of the association between alcohol drinking and smoking, aldehyde dehydrogenase-2 (ALDH2) status, alcohol dehydrogenase-2 (ADH2) status, any history of abnormal liver function, and hepatitis B and C viral infection. The subjects included 207 male workers who had been followed-up with respect to liver function periodically since 1992. Information relating to current alcohol consumption and smoking habits was obtained by an interviewer-administered questionnaire in 1996, and any history of liver function and hepatitis B and C virus infection was obtained from previous medical surveillance. Genotypes of ALDH2 and ADH2 were determined by polymerase chain reaction/restriction fragment polymorphism assay. Results have revealed that smoking and ALDH2 1-1 status were associated with current alcohol consumption (respectively: odds ratio, 23.3; P < 0.01 and odds ratio, 14.5; P < 0.05). Neither a history of abnormal liver function nor a history of hepatitis B and/or C infection was associated with current alcohol consumption. It seems that only those with ALDH2 1-1 who are smokers consume alcohol. We conclude that smoking and inherited ALDH2 1-1 are the most important determinants of alcohol consumption. In addition to the medical advice of physicians in their yearly health check-ups, worksite health-promotion programs based on both alcohol consumption habits and smoking cessation should be instituted forthwith, particularly for those who demonstrate the potential for developing liver damage.
