Purpose: The purpose of this study was to understand the level of problem drinking, insight of problem drinking, and stress coping on male manufacturing workers in a community area. Methods: Data were collected from 181 manufacturing workers at two industries located in G city from September to October 2021. The collected data were analyzed with frequency, descriptive statistics, one-way ANOVA, and Scheffe test using the SPSS 22.0 program. Results: According to the level of problem drinking, “social drinkers” were 53.1%, “problem drinkers” 30.3%, and “alcoholics” 16.6%. Of the subjects, 49.7% in the “poor insight group,” 33.7% in the “fair insight group,” and 16.6% in the “good insight group.” There was a significant difference in the insight of problem drinking (F=13.56, p<.001) and stress coping (F=5.33, p=.006) according to the level of problem drinking. Conclusion: These result suggest that it is necessary to develop various strategies for drinking problems in male manufacturing workers to create a safe work environment.
