Background : Being upright (sitting, chairs, squatting, kneeling) has advantages for pregnant women during the labor. Prenatal childbirth education helps them to be better prepared and feel more confident to promote vaginal delivery.
Objective : To study the results of prenatal childbirth preparation to adopt the upright position during the labor. Material and method : This prospective, non-randomized, concurrent controlled trial compared 200 singleton parturients who were encouraged to adopt the upright position during the labor with 200 others who served as a control group. Women in the study group attended an education class about the benefits of being upright and practiced at the gestational age of 32-36 weeks. During the labor, utilizing upright positions were assessed by Likert scale every 1 hour in latent phase and 30 minutes in active phase. Duration of labor, assisted deliveries, birth weights and use of pethidine were recorded. Comparison between groups was analyzed by Mann-
Whitney U test. 
Results : The mean age was not different between groups but women in the study group were taller and had higher educational level. In latent phase, 48 women had maternal or fetal complication and were excluded. Among 176 remaining parturients in each groups, women in the study group kept upright positions better than the control group significantly (p<0.001) but not different in active phase (p=0.588). Duration of labor in the first stage was shorter in the study group (152.3 ± 113.8 vs 195.4 ± 147.6 minutes, p=0.007), especially in nullipara (p=0.024) but not different in multipara (p=0.293). There was a non-significant reduction in duration of second stage in the upright group (23.6 ± 21.3 vs 26.6 ± 23.6 minutes, p=0.416) or increment of normal vaginal delivery rate (87.5% vs 78.4%, p=0.070).
Conclusion : Prenatal childbirth preparation at the gestational age of 32-36 weeks promoted utilizing the upright position during the latent phase of the labor. The shortening duration of labor was apparent only in the first stage.
