To collect data, a demographic information questionnaire and the Health-Promoting Lifestyle Profile II (HPLP-II) were used. Minimum and maximum scores of HPLP-II were 48 and 192, respectively. Data analysis was conducted using t-test, one-way ANOVA, Tukey&#39;s multiple comparison test, and non-parametric Kruskal-Wallis test.</span></p> <p dir="ltr" style="text-align: justify;"><span style="font-family: times new roman;"><strong>Results:</strong> In this study, 58.8% of the participants were women. The mean age of the participants was 22.50 &plusmn; 2.16 years. The mean and standard deviation of the HPLP-II score of the medical students was 109.74 &plusmn; 18.65. There was a significant relationship between health-promoting lifestyle and variables of age (P = 0.007), university entrance year (P < 0.001), mother&rsquo;s education level (P = 0.003), and father&rsquo;s education level (P = 0.011). However, no relationship was observed between health-promoting lifestyle and parental occupation and place of residence (P > 0.050).</span></p> <p dir="ltr" style="text-align: justify;"><span style="font-family: times new roman;"><strong>Conclusions:</strong> This study showed that the status of health-promoting lifestyles in medical students of RUMS was at a moderate level, but it is still at a great distance to the optimal level.
