Japan Society of Obstetrics and Gynecology defines prolonged labor as labor more than 30 hours in primiparas and 15 hours in multiparas. Such a definition corresponds to 98th percentile and 97th percentile in duration of labor in 660 primiparas and 641 multiparas in present study, respectively. The 90th percentile of durations of labor was 20 hours in primiparas and 10 hours in multiparas. Using a Mann-Whitney U test, significant decreases in 5 minute Apgar score were found in primiparas with labor more than 20 hours and in multiparas with labor more than 10hours (P=0.013, P=0.035, respectively). These findings suggest that prolonged labor may be defined as labor more than 20 hours in primiparas and 10 hours in multiparas.

日本妇产科学会将产程延长定义为初产妇产程超过 30 小时，经产妇产程超过 15 小时。这一定义分别对应于本研究中 660 名初产妇和 641 名经产妇的产程持续时间的第 98 个百分位和第 97 个百分位。 90% 的初产妇产程持续时间为 20 小时，经产妇产程持续时间为 10 小时。使用Mann-Whitney U检验，发现产程超过20小时的初产妇和产程超过10小时的经产妇5分钟Apgar评分显着下降（分别为P=0.013、P=0.035）。这些发现表明，产程延长可能被定义为初产妇产程超过 20 小时，经产妇产程超过 10 小时。
