Background: Health-promoting behaviors assist individuals to prevent disease, promote health, increase longevity, and enjoy a better quality of life. A number of interpersonal, social, and environmental factors have been shown to influence healthpromoting behaviors. Little empirical evidence exists about the predictors of health-promoting behaviors among migrant workers.

Purpose: This study uses Pender’s health promotion model to describe and identify the predictors of health-promoting behaviors in Nepalese migrant workers in Korea.

Methods: A cross-sectional research designwas used. Nepalese migrants who had been working in South Korea (n = 169) for over 6 months were surveyed between July and December 2012. Self-efficacy was measured using the Perceived Health Competence Scale, the Health-Promoting Lifestyle Profile II was used to measure health-promoting lifestyle behaviors, and perceived health status was measured using a single-item question. Descriptive statistics, correlation analysis, andmultiple regression analysis were used to analyze data.

Results: Spiritual activity was the highest reported healthpromoting behavior, whereas physical activity was the least practiced behavior. Self-efficacy was the only significant predictor of health-promoting behavior.

Conclusions: The results of this study suggest that future health-promoting interventions should enhance the selfefficacy of target populations for individual health behaviors. Factors such as working conditions, culture, and economic background that may affect the health-promoting behaviors of migrant workers must be considered when planning nursing interventions. Multicultural nursing structures and policies are needed to reach out proactively to all adult migrant groups.
