Data is gathered with demographic and “Health-Promoting Life Style Profile II” (HPLPII) in six dimensions of health responsibility, physical activity, nutrition, spiritual growth, stress management and interpersonal relationships.  In the present study, Cronbach's alpha and test-retest reliability of the tool was calculated in a sample of 10 people within a week, also intra-class correlation coefficient (ICC) is calculated.

The highest score is in the area of health responsibility (32.40 ± 5.83) and the lowest score corresponds to the stress management (13.13 ± 3.34) and physical activity (13.45 ± 4.67). Results showed a significant correlation between health promoting behaviors and the shift work (P = 0.021), type of employment (P = 0.001) and income (P = 0.002).

Conclusions: Considering the low score of nurses in physical activity and stress management, it is recommended to improve the health promotion behaviors especially stress management and physical activity among through implementing educational programs about healthy life style.
