The data were analyzed by SPSS 16, using descriptive statistics, independent t-test, and Pearson correlation coefficient. 

19% of the subjects scored above 85 and 6% of them scored higher than 100 on the WDE-Q. Also, 24.8% of these women scored less than 50 on the WHO-5. The studied women’s mean fatigue index was 20.3±12.7. Fear of childbirth had a positive correlation with fatigue (r=0.235) and a negative correlation with well-being (r=0.310) (P < /em><0.05).
