The purpose of this thesis is to measure the duration of active labor (first and second stages) for low-risk, nulliparous women attended by Certified Professional Midwives (CPM) who had completed planned deliveries at home or in freestanding birth centers. Basic descriptive statistics were analyzed for 789 nulliparous women in the Midwives Alliance of North America (MANA) Statistics Project 2004-2007 dataset. Results show that the mean length of active first stage of labor was 7.2 hours, standard deviation (SD) was 6.2 hours, and the statistical upper limit (mean +2 SD) was 19.6 hours. The mean length of second stage was 79 minutes, the SD was 73 minutes, and the statistical upper limit was 225 minutes. The results are discussed and related to published literature on active labor duration for healthy, low-risk women. This thesis provides a strong foundation for further research that addresses differences in the duration of second stage for women having planned birth center or home births compared to those having planned hospital births, as well as more information about the care provided by Certified Professional Midwives (CPM).
