The purpose of this study was to investigate the stress, dietary habits, dietary behaviors, and health-related behavior of nurses.


The subjects of this study were 161 nurses studying at a cyber university. The general characteristics, stress, dietary habits, dietary behaviors, and health-related behavior of the subjects were surveyed using a self-administered questionnaire in October, 2010. The subjects were divided into two groups according to the working pattern: shift workers (n = 110) and non-shift workers (n = 51).


In the general characteristics, there were significant differences in marriage, monthly income, employment type, and job satisfaction between the two groups. Total stress score did not differ significantly between the two groups. In dietary habits, significant differences in meal regularity, skipping meals, skipping reasons, having regular mealtimes, frequency of snack and the snack time between shift workers and non-shift workers (p<0.05). Total score of dietary behaviors in shift workers was significantly lower than that in non-shift workers (p<0.05). Score of shift workers in taking three meals per day regularly was significantly lower than that of non-shift workers. In health-related behavior, a significant difference in sleeping time was observed between shift workers and non-shift workers. Dietary behavior showed negative correlation with shift work (r = 0.176) and positive correlation with health consciousness (r = 0.210) and perceived health status (r = 0.198) in subjects after adjustment for age, marriage, monthly income, and employment type (p < 0.05). Multiple regression analysis revealed that shift work, health consciousness, and perceived health status affected dietary behavior in subjects.


These results indicate that shift working nurses had poor dietary habits and dietary behaviors, and these dietary behaviors are affected by their shift work, health consciousness, and perceive health status.
