Health-promoting behaviors and self-efficacy among nursing students in times of uncertainty.

This study further emphasizes the importance of regular physical activity (at least 3 h a week) as a strategy to improve HPB among nursing students. Culturally sensitive strategies that aim to enhance HPB should be embedded in undergraduate nursing curricula. Public health nurses and university counselors should join efforts to develop strategies to maintain or enhance self-efficacy and to promote regular physical activity among nursing students. Future research should further study the association between self-efficacy, resilience, and uncertainty in contexts of ongoing conflicts.
