Abstract Background Nursing students play a role in promotion of public health as health promoters and professional care providers. Therefore, health-promoting behaviors in nursing students and their self-efficacy for health practices are important in providing better services to patients and clients. With regard to the importance of these factors in the academic progress of students, this study was conducted to examine the level of health-promoting behaviors among nursing students and its relationship with self-efficacy for health practices and academic achievement. Methods This descriptive and correlational study was conducted on 217 nursing students of a large university of medical sciences in the south of Iran in 2016. Data were collected using the Persian version of the health promotion lifestyle profile (HPLP II), self-rated abilities for health practices scale (SRAHPS) and the grade point average of the students (levels A, B, C). Results The mean health-promoting behaviors (2.48 ± 0.35) and self-efficacy for health practices of the students (2.55 ± 0.62) were moderate. The mean score of the students’ academic achievement was at level B (16.02 ± 1.85). The health-promoting behaviors were significantly correlated with self-efficacy for health practices (r = 0.623, p < 0.0001) and academic achievement (r = 0.285, p < 0.0001). Moreover, self-efficacy for health practices was significantly correlated with academic achievement (r = 0.282, p < 0.0001). Conclusion The correlation between the health-promoting behaviors and health self-efficacy with academic achievement can be a good basis in devising health and educational programs for students. In planning for promoting academic achievement and health-promoting behaviors of students, it is essential to pay special attention to enhancement of self-efficacy for health practices.
