“…few known causal factors influencing first stage duration are maternal age, increasing BMI, posterior fetal position and higher fetal weight [34][35][36][37][38][39][40]. Compared to the African and American cohorts, the Swedish cohort was older, had lower BMI, lower gestational age at birth, and fetal weight was higher.…”

To describe the duration, progression and patterns of first stage of labor among Swedish women. Design Population-based cohort study. Population Data from Stockholm-Gotland Obstetric Cohort 2008-2014 including ¼ of all births in Sweden, the final sample involved a total of 85,408 women with term, singleton, vertex, live fetuses experiencing spontaneous labor onset and vaginal delivery with normal neonatal outcomes. Main outcome measures Time to progress during first stage of labor using three approaches: 1) Traverse time in hours to progress centimeter to centimeter, 5 th , 50 th (and 95 th percentile); 2) Dilation curves for different percentiles, and; 3) Cumulative duration for the 95 th percentile by parity and dilation at admission. Results Variation in both the total duration and the trajectory of cervical change over time is large. Similar to the general held view, the rate of cervical dilation accelerates at 5-6 centimeters. Among nulliparous women, the median time found in our population was faster than their

“…Multiparity was a protective factor of infectious diseases may be because of the shorter time of the duration of labor. It is known that the cervical dilation rates and foetal descent process of multiparous women is faster than that of nulliparous women [ 31 , 32 ], and we concluded that the shorter labor process may be the reason of lower risk of infection.…”

Background The aim of this study was to describe the epidemiology of prelabour rupture of membranes (PROM) in China and to assess the association between clinical practice following the guidelines and early neonatal infections. Methods We conducted a prospective cohort study of 15926 deliveries in ShenZhen Baoan Women's and Children's Hospital, Xibei Women's and Children's Hospital and Chengdu Women's and Children's Hospital between August 1, 2017, to March 31, 2018. Clinical data were collected for each participant. The epidemiology of PROM was described. The association between PROM with early neonatal infectious outcomes and the influence of the implementation of the guideline on early neonatal infectious outcomes were assessed. Findings The incidence of PROM was 18•7%. PROM was showed to be a risk factor for neonatal infectious diseases (adjusted OR 1•92, 95%CI 1•49~2•49, p <0•0001), early-onset pneumonia (EOP) (adjusted OR 1•81, 95%CI 1•29~2•53, p =0•0006) and early-onset sepsis(EOS) (adjusted OR 14•56, 95%CI 1•90~111•67, p =0•01) for term neonates. For term neonates born from mother with PROM, induction of labor according to the guideline was a protective factor for neonatal diseases(adjusted OR 0•50, 95%CI 0•25~1•00, p =0•00498) and EOP(adjusted OR 0•32, 95%CI 0•11~0•91, p =0•03). For preterm neonates born from mother with PROM, using antibiotics according to the guideline showed to be protective for neonatal infectious diseases (adjusted OR 0•14, 95%CI 0•09~0•23, p <0•0001) and EOP (adjusted OR 0•08, 95%CI 0•04~0•14, p <0•0001). Interpretation Our study showed the risk of PROM for infectious diseases (including EOP and EOS) and the benefit of the usage of antibiotics according to the guideline for infectious diseases and EOP for preterm neonates.

“…Duration of is shorter in multiparous compared to nulliparous women, with a range for nulliparous (0.29-1.57 cm/h), and multiparous (0.32-4.47 cm/h) women [4][5][6]. However, comparability between studies is compromised as the de nition of the onset of the active rst stage of labour differs.…”

“…Additionally, Friedman postulated a linear progression curve of 1 cm/h and de ned the beginning of active phase at 3-4 cm [1]. Since, multiple studies have challenged the Friedman curve and found that progression of labour can be slower and non-linear with a range for nulliparous (0.29-1.57 cm/h), and multiparous (0.32-4.47 cm/h) women [4][5][6]. This wide variability of labour progression is most likely explained by an interindividual variation as well as other potential factors, such as the neonatal birthweight or head circumference.…”

Purpose Labour is shorter in multiparous women. However, there is no individualized data on differences in duration of labour for consecutive deliveries in the same parturient. Methods We conducted a retrospective data analysis from 2004–2021 at the University Hospital of Zurich and included all women with 2 or more vaginal deliveries of a singleton child in cephalic position, between 22 and 42 weeks of gestation. Descriptive statistics were performed with SPSS version 25.0 (IBM, SPSS Inc., USA). The primary endpoint was the ratio between duration of labour stages in consecutive deliveries of the same parturient. Results A total of 3344 women with 7242 births (2601 first [P0], 2987 second [P1] and 1176 third [P2]) were included. The active first stage of labour was 51% shorter (95% CI 0.47–0.51, p < 0.001) and the second stage of labour was 74% shorter (95% CI 0.24–0.27, p < 0.001) in P1 compared to P0. Higher birthweight of the first child led to an even greater decrease in duration of the second stage of labour in P1 compared to P0 (p = 0.003). Neuraxial anaesthesia was an independent risk factor for a longer duration of labour, irrespective of parity (p < 0.001). Birthweight and HC of the neonates did not significantly differ between the children born by the same women. However, higher birthweight in of the first child significantly augmented the rate of second stage of labour between P0 and P1 (p = 0.003). Discussion Up to the third delivery, duration of labour decreased with each consecutive delivery of the same parturient. An individualized assessment of the expected duration of labour in multiparous women should be encouraged.
