Purpose: Similar to other service sectors, the hotel industry is a labor-intensive field that relies heavily on human interaction to deliver intangible services. This study aimed to identify factors influencing health promotion behaviors among hotel employees. Methods: Data were collected from 177 hotel employees between December 24, 2024, and January 15, 2025. The questionnaire assessed self-efficacy, job stress, and emotional labor, health promotion behavior. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation, and multiple linear regression with SPSS/WIN 29.0. Results: Health promotion behavior was significantly and positively correlated with self-efficacy (r=.47, p<.001), negatively correlated with job stress (r=-.36, p<.001), and emotional labor (r=-.22, p=.003). The following factors had significant effects on health promotion behavior among hotel workers and together explained 33.0% of the variance: self-efficacy (β=.34, p<.001), perceived health status as “good” (β=.31, p<.001) and ”fair” (β=.27, p=.002), and “shift” work schedule (β=-.14 p=.031). Conclusion: These findings suggest that an integrated approach targeting self-efficacy enhancement and improved perception of subjective health status, along with organizational-level support to mitigate the environmental constraints of shift work, is essential for promoting health behaviors among hotel workers.
