Subjects and methods A comparative cross sectional study was conducted upon (150) shift nurses and a matched comparative group of (150) day time nurses from Mansoura University Hospitals. The studied groups were interviewed using structured questionnaire. Anthropometric measurements including height, weight, waist circumference and BMI were done. Blood pressure of studied group was measured. Result There was statistically significant as regard gastrointestinal disorder symptoms ,i.e. disturbed appetite, nausea, constipation or diarrhea and stomach upset among shift nurses compared to day time nurses .As regard cardiovascular disorder symptoms, It was found that heart palpitation, irregular heart beats; chest pain and dizziness were more frequent among shift work nurses compared to day time nurses. Regarding the pattern of menstrual cycle among studied group, there was no statistically significant different (p 0.05), before starting the work. However menstrual cycle pattern have been changed since starting the work to become more frequently irregular among shift work nurses (66.6%) compared to day time nurses(14%) with statistically significant difference (p 0.001). Current research results have reported that 49.3% of shift nurses were obese, while 27.3% of day time nurses were obese.

The metabolic disorders criteria were more frequent among shift nurses compared to day time nurses with statistically significant differenc.
