“…It is important to mention that there is a constant increase in the duration of second stage along with maternal age without the existence of a certain cutoff point. This finding is in accordance with the pattern suggested in earlier studies by Friedman and Sachtleben, 7 Cohen et al ., 8 and Adashek 9 . According to their theory, there is a gradual decrease in myometrial function with increasing age.…”

The purpose of this study was to investigate the relationship between parity, maternal age at delivery, gestational age, and duration of the second stage of labor. In this article a retrospective analysis of deliveries during the period from 2000 to 2005 in our Institution was made. We recorded 208 pregnant women under the age of 20 years, 6,115 between 20 and 40 years, and 188 over the age of 40 years considering parity, duration of second stage of labor, birth weight, and gestation age. The correlation of the above parameters was statistically analyzed. In primigravidas, under the age of 20 years, the second stage of labor was significantly shorter compared to women aged over 40 years, and significantly shorter compared to women between the age of 20 and 40 years. Gestational age at delivery was significantly shorter in women aged over 40 years compared to those under the age of 20 years as well as to those between 20 and 40 years of age. Age was positively correlated to the duration of the second stage of labor and negatively correlated to the gestation age at delivery. In multigravidas, age was negatively correlated to the gestational age at delivery. In primigravidas, maternal age was positively correlated with the duration of the second stage of labor. On the contrary, gestational age at delivery was negatively correlated with maternal age. In multigravidas, a negative correlation between maternal age and gestational age at delivery was statistically significant.

“…In their analysis of 26 control-matched gravidas, Sokol et al concluded advanced maternal age was not associated with labor prolongation (24). With respect to the second stage length, our findings agree with other studies in that second stage increases directly with age with and without an epidural (6–8, 25–26). …”

“…We have additionally found a relationship between maternal age and labor progression seen in our labor curves that has not been previously demonstrated. In 1965, Friedman and Sachtleben evaluated labor length in 3,329 nulliparous women and found no important difference in the course of labor that could be ascribed to maternal age when comparing the young (less than 18 years old) and the older (greater than 35 years old) parturient (8). However, the authors note that their study may not have been powered to find a significant difference.…”

“…The relationship between cesarean delivery and age is unclear but likely is influenced by other maternal and fetal factors. Women giving birth today are not the same as the cohort of women used to create the Friedman labor curves, which are often used today to identify normal versus abnormal labor progress (6–8). Based on more recently published literature, women today are older, heavier, vary in ethnicity and are more likely to undergo assisted reproduction (1, 9–10).…”

Objective To evaluate labor progress and length according to maternal age. Methods Data were abstracted from the Consortium on Safe Labor, a multicenter retrospective study from 19 hospitals in the United States. We studied 120,442 laboring gravid women with singleton, term, cephalic fetuses with normal outcomes and without a prior cesarean delivery from 2002 to 2008. Maternal age categories were less than 20 years old, greater than or equal to 20 to less than 30, greater than or equal to 30 to less than 40 and greater than or 40 years old, with the reference being less than 20 years. Interval-censored regression analysis was used to determine median traverse times (progression cm by cm) with 95th percentiles, adjusting for covariates (race, admission body mass index, diabetes, gestational age, induction, augmentation, epidural use and birth weight). A repeated-measures analysis with an eighth-degree polynomial model was used to construct mean labor curves for each maternal age category, stratified by parity. Results Traverse times for nulliparous women demonstrated the time to progress from 4 to 10 cm decreased as age increased up to age 40 (median 8.5 hrs vs. 7.8 hrs in those greater than or equal to 20 to less than 30 year old group and 7.4 hrs in the greater than or equal to 30 to less than 40 year old group, p<0.001); the length of the second stage with and without epidural increased with age (p<0.001). For multiparous women, time to progress from 4 to 10 cm decreased as age increased (median 8.8 hrs, 7.5, 6.7 and 6.5 from the youngest to oldest maternal age groups, p<0.001). Labor progressed faster with increasing maternal age in both nulliparous and multiparous women in the labor curves analysis. Conclusion The first stage of labor progressed more quickly with increasing age for nulliparous up to age 40 and all multiparous women. Contemporary labor management should account for maternal age.

“…It appears from this study that such a relationship does exist. Some authors, 2,13 in studying the possibility of this relationship, have determined that there are no important differences in the course of labor in nulliparas that could be related to maternal age. Others 4,6‐8 either have speculated or concluded from their studies that the older nullipara will have an increased risk of labor dysfunction.…”
