Objective: To examine the association between working hours and problem drinking in employees from different employment grades.
Methods:We used data from a national survey of randomly sampled Taiwanese workers. A total score of 2 or more on the Cut down, Annoyed, Guilty, and Eye-Opener (CAGE) questionnaire was used to identify problem drinkers. Weekly working hours were categorized into five groups: <40, 40, 41-48, 49-59, and ≥60. Employees were classified into three employment grades: managers and professionals, skilled workers, and low-skilled workers. The associations between working hours and problem drinking in employees from different employment grades were examined by logistic regression models.Results: In skilled workers, problem drinking was associated with <40 and 41-48 working hours, but not with >48 working hours. In low-skilled workers, problem drinking was most strongly associated with 49-59 working hours.
Conclusion:The association between working hours and problem drinking was not linear and differed with employment grades. K E Y W O R D S alcohol, employment grade, problem drinking, socioeconomic status, working hours Am J Ind Med. 2019;62:404-411. wileyonlinelibrary.com/journal/ajim 404 |
