These develop ments include lack of deceleration phase and quick progression in active phase due to the differences in age, race and increase of midwifery interventions during the delivery. This study was performed to compare modern labor curve with Friedman curve.   Material and Methods: The present descriptive study was performed on 665 parturient women who referred to Fasa Shariati hospital during one year. Inclusion and exclusion samples had not taken any sedation or induction for labor. Data were collected by educated midwives.   Results: There was a significant difference between the two groups regarding the mean of dilatation velocity (p<0.05) and second stage of labor (p<0.001). However, a significant difference was not observed between the active phase and third stage of labor. Also the mean of active phase and second stage of labor in both nulli and multipara women of today showed a significant difference with the women in the Friedman study (p<0.05).   Conclusion: This study shows that the labor curve of these days is different with Freidman labor curve and the maximum of dilatation velocity happens in over 5 cm. Therefore, it is suggested to avoid any early midwifery and surgery intervention before 5 cm dilatation.   Key words: Labor, Nullipara, Multipara, Freidman curve     Funding: This research was funded by Fasa University of Medical Sciences.   Conflict of interest: None dectared.   Ethical approved: The Ethnics Committee of Fasa University of Medical Sciences approved the study.     [1] - Academic Member, Dept. of Epidemiology, Paramedical School, University of Medical Science, Arak, Iran   (Corresponding Author) Tel: (0861) 4173526, Fax: (0861) 4173526, E- mail: [email protected]   [2] - Assistant Prof., Dept. of Epidemiology, Health School, University of Medical Sciences , Shiraz, Iran   [3] - Master of Epidemiology, University of Medical Sciences, Arak, Iran   [4] - Assistant Prof., Dept. of Gynecology and Obstetrics, Medical School, University of Medical Sciences , Fasa , Iran
