Method ：The study subjects were female nurses who were 20-45 years old and lived in Kaohsiung metropolitan. All the study nurses were asked by questionnaire about their time-shift working status, status of menstruation, quality of sleep, lives birth, and reproductive system. Data were analyzed by Statistical Package for Social Science (SPSS). Results：Compared to day-shift nurses, night-shift nurses had a higher opportunity to have irregular menstruation cycles and premature babies (p<0.05). The averaged sex ratio among the study nurses’ babies was 0.9. The sex ratio among the night-shift nurses’ babies was 1.008, which was significantly higher than that in day-shift nurses’ babies (0.67). Conclusion：Night-shift task can cause female nurses to have irregular menstruation and premature babies. In addition, night-shift nurses have more chances to have male babies than day-shift nurses. Key words：Nurse, night-shift task, sex ratio, birth outcome
