Immigration, domestic labor, and earnings inequality among native-born women in the US

ABSTRACT The wage effects of immigration have been widely studied, yet much of the research has focused on competitive threats to low-skilled native-born men. In contrast, this paper applies a gender lens to explore possible complementary relationships between immigration-induced outsourcing of domestic work and the earnings of native-born women, while recognizing the classed and racialized nature of domestic labor. Empirically, this article examines subgroup variations in earnings among full-time employed native-born women by education and race/ethnicity in relation to the state share of immigrants in the domestic service sector. The analysis combines data from the 2012 American Community Survey with state-level work-family policy data collected for 2010, accounting for compositional differences and selection into the labor force. Likely due to increased availability of affordable domestic services, the results show a higher immigrant share is associated with greater earnings for native-born women overall. However, education and race/ethnicity moderate this association, indicating that highly educated non-Hispanic white women benefit more than other women because the labor process and outsourcing of household production are classed and racialized. Hence, states with a higher share of immigrants filling domestic services exhibit wage dispersion patterns that reinforce intersectional inequality among native-born women.

Review of the new facts or new news contained in article 321 of the Chilean Civil Procedure Code

This paper aims to address the procedural figure of new facts or newly discovered events, recognized in some continental Procedure Codes. In this context, we will examine certain historical sources that influenced its modern legislative reception, intending to understand the institution’s meaning, which is usually studied from an evidentiary perspective, with Chilean Civil Procedural Law serving as an example. In contrast to the above, our manuscript will assert that the new facts or newly discovered events , contained in article 321 of the Chilean Código de Procedimiento Civil, operate as a legislative mechanism aimed at incorporating new factual background, expanding the subject matter of the trial, and breaking the fiction of immutability of the process derived from the general principle of the doctrine of lis pendens, which justifies the application of the institution to the Chilean labour process.

Aggravated commodification as a new dimension of precarity in platform economy

The concepts of precariousness that emerged in Western countries from the 1980s onwards highlight uncertainty regarding the form, scope and nature of labour in the near future. In this article, we use the concept of aggravated commodification as a new dimension of precariousness faced by platform workers. This concept is derived from Polanyi’s idea of fictitious commodities and is treated as a form of labour-market expansion. Applying critically evaluated theory of Karl Polanyi, the article argues that platforms transform labour into a commodity, potentially leading to exploitation and societal unrest. Aggravated commodification refers to work arrangements that introduce (three-sided) market mechanisms within the labour process. Moreover, thanks to the technological infrastructure platforms are leading to the commodification of activities previously performed outside the market and free absorption of activities that were previously a part of wage labour. The study contributes a comprehensive framework for understanding and enriching discussions on precarity in the context of platform capitalism, especially within Central and Eastern European countries.

Problems of reproductive risk management in occupational medicine and issues of causation

In the Russian Federation, 2024 has been declared the year of the family, which, in the context of the growth of domestic industrial production, determines the importance of preserving the reproductive health of women working in harmful and unfavorable working conditions, preventing the adverse effects of factors in the working environment and the labor process on women’s health indicators. The review examines publications presented in the RSCI, PubMed, Scopus, and Google Scholar databases, which cover mainly the last 10 years (2013–2023)

Induction of Labour: What to Consider

Induction of Labour (IOL) is a method of artificially providing stimulus to the uterus to start the process of labour.1 It utilises iatrogenic therapies such as a synthetic oxytocin, cervical ripening medications, in conjunction with the artificial rupture of membranes, to imitate the physiology of labour and childbirth.2 The indication for IOL is dependent on the clinical need to optimise maternal, fetal and neonatal outcomes, juxtaposed with the potential adverse effects of the IOL process. Indications include uterine, placental and fetal growth disorders, hypertensive conditions and diabetes.3 For example, the National Institute for Clinical Excellence (NICE) recommend IOL between 37 and 38 plus six weeks for pregnant populations who have type 1 or type 2 diabetes, to prevent stillbirth and associated complications.4 The absolute effectiveness of IOL intervention in preserving maternal and fetal health is evident5 however, the World Health Organization (WHO) endorses the consideration of choice of IOL method.6

Optimizing labor duration with pilates: evidence from a systematic review and meta-analysis of randomized controlled trials

BackgroundPilates has captured interest due to its possible advantages during pregnancy and childbirth. Although research indicates that Pilates may reduce labor duration, alleviate pain, and improve satisfaction with the childbirth experience, consensus on these outcomes remains elusive, underscoring the necessity for additional studies.AimThis systematic review and meta-analysis aimed to assess the impact of Pilates exercises on labor duration among pregnant women.MethodsThe online database was searched to yield the literature using the terms of ‘Pilates’, ‘childbirth’, and ‘labor duration’, and similar terms including PubMed, Clinical Key, Scopus, Web of Science, Embase, and Cochrane Database of Systematic Reviews up to June 25, 2023. Studies were considered eligible if they were randomized or clinical controlled trials (RCTs/CCTs) published in English, focusing on healthy pregnant women without exercise contraindications. The studies needed to include interventions involving Pilates or exercise movement techniques, a comparison group with no exercise, and outcomes related to labor duration, the period of the active phase, and the second stage of delivery.ResultsEleven studies, totalling 1239 participants, were included in the analysis. These studies provided high-quality evidence from exercise only RCTs/CCTs. The findings indicated a significant reduction in the active phase of labor (8 RCTs, n = 1195; Mean Difference [MD] = -56.35, 95% Confidence Interval [CI] [-89.46 to -23.25]) and overall labor duration (8 RCTs, n = 898; MD = -93.93, 95% CI [-138.34 to -49.51]) in pregnant women who engaged in Pilates exercises compared to those who did not but doesn’t affect on the duration of the second stage of labor (7 RCTs, n = 1135; MD = -0.11, 95% CI [-7.21 to 6.99]).ConclusionsWhile this review primarily addresses the effects of Pilates on healthy and low-risk pregnant women, the findings suggest a potential role for Pilates in shortening labor duration. Therefore, engaging in Pilates or similar physical activities is recommended for pregnant women to potentially facilitate a more efficient labor process.

Інноваційні рішення як джерело розвитку агробізнесу

The article examines the role and prerequisites for using innovative solutions to improve the efficiency and competitiveness of modern agribusiness. The article examines the role and prerequisites for using innovative technologies to improve the efficiency and competitiveness of modern agribusiness. Searching for scientific and practical solutions focuses on analyzing current trends, opportunities, and challenges associated with implementing innovative solutions in agribusiness. It is highlighted that global trends in the development of critical economic factors (labor, capital, technology) create both new opportunities and threats for the development of companies. It is substantiated that the reduction of working-age people threatens the development of rural areas and the provision of agricultural enterprises with labor. It is proved that most of the labor processes carried out in agricultural companies today require manual skills. The current trends in labor shortages in agricultural companies are highlighted, which is compensated for by the growth of labor productivity, but its level, due to the relatively low provision of enterprises with material and technical resources, still does not allow organizing agricultural business at the level corresponding to the leading countries. During the study, the methodology of theoretical generalization, as well as analysis and synthesis, was used, which allowed us to deepen and structure the understanding of the transformative potential of innovative technologies in agriculture at the present stage of development of innovative technologies. It has been found that innovative technologies play a crucial role in increasing the efficiency, competitiveness, and sustainability of agribusiness by optimizing production, and improving the transparency and traceability of operations and processes. Keywords: innovative technologies, agribusiness, agriculture, agricultural production, shortage of personnel, threat of unemployment, labour processes, introduction of innovations, efficiency, competitiveness.

Effect of production factors on the relative telomere length of ICR mice

Currently, the issues of studying the quantitative assessment of the isolated effects of physical and chemical occupational factors of low intensity, severity and intensity of the labor process on the telomere relative length (TRL) are relevant in order to establish the mechanisms of development of premature aging. The aim is to evaluate the effect of isolated exposure to low–intensity physical and chemical occupational factors on the relative length of telomeres in an animal experiment. Material and methods. ICR mice (n = 65) are distributed in equal numbers into 3 test groups (exposure to vibration, noise, chemical exposure) and 1 control group (contained in comfortable conditions and not exposed to these factors). The duration of the experiment was 90 days, samples for DNA isolation from the striated muscle tissue of ICR mice thigh were taken on days 0, 30, 60 and 90. TRL was measured using real time PCR. Results and discussion. The results of the study indicate a significant shortening of TRL on the 90th day in the control group compared to the initial indicators, which may indicate the general processes of aging of animals. A long (90-day) stay of ICR mice in conditions simulating the isolated influence of various occupational hazard factors (vibration, noise, chemicals) operating at a level of 1.5 MAC, MPL, was accompanied by unidirectional dynamics of TRL. The chemical factor has the greatest impact on TDC (a decrease in TDT relative to the value of the control group is noted on the 30th, 60th and 90th days of the experiment), the physical factor causes a shortening of TDT after 60 and 90 days. Conclusions. Further study of the isolated influence of occupational factors on the TRL change in model organisms will contribute to the establishment of mechanisms that prevent the development of pathological processes in workers under conditions of production hazards.

LABOR VALUES IN THE PERCEPTION OF THE MILLENNIAL GENERATION IN THE CONDITIONS OF DIGITALIZATION

The purpose of the article is to explore the perception of work values as a marker of identity by the millennial generation in the context of the global digitalization of society. The millennial generation, being a significant part of the country’s economically active population, demonstrates its understanding of decent work, expressed in work preferences and value orientations, which, in turn, serves to determine the identity of this age group. Digitalization has contributed to the development and diversification of the employment sector by offering alternative forms, which has greatly changed the understanding of decent work. Based on data from a sociological study of formalized interviews among representatives of the millennial generation (n = 300), the key components of work values and their influence on the professional activity of representatives of the generation being studied were identified. The desire of millennials for career growth and professional self-improvement as the main labor value has been established; we can talk about a balance between external and internal labor orientations. It was revealed that an integral part of decent work for them is the presence of an expanded social package, including voluntary health insurance (VHI), and flexible work schedules. Millennials demonstrate high adaptability to changing conditions of the labor market and openness to innovation in organizing the labor process, which is manifested in a preference for remote forms of employment, opportunities for retraining and development. In the future, it is possible to study the attitudes towards work of millennials and centennials from a comparative perspective. The results of the article are of interest to those specializing in the field of sociology of labor and sociology of youth. The sociological research data can be used in the practical organization of labor activities to optimize personnel management and create a corporate culture that meets the needs of the new generation of workers.

The Role Of Family Support In Childbirth: Implications For Maternal And Infant Well-Being

Labor is a critical moment in the life of both mother and baby, often accompanied by physical and emotional challenges. Family support, whether emotional, physical, or informational, plays an important role in influencing the quality of the birth experience and health outcomes. This study used a qualitative approach with literature review as the main data collection technique. This study aims to explore the role of family support in the labor process and its implications for maternal and infant well-being. The literature study approach was used to identify and analyze various research, theories, and empirical reports relevant to the topic. The study results show that emotional support from family can reduce maternal anxiety, increase a sense of security, and improve the overall labor experience. Physical support, such as massaging or helping the mother move, contributes to a smoother labor process and minimizes the need for medical intervention. Informational support helps mothers understand the stages of labor and make better decisions regarding health care. In addition, family support improves the quality of care provided to the baby, helps the mother to be more responsive to the baby's needs, and supports a strong emotional bond between mother and baby. The implications of these findings emphasize the importance of family involvement in childbirth and the postpartum period to improve the well-being of mothers and infants. Health workers are advised to encourage family participation and provide adequate education on the role of family support, to ensure that mothers and infants receive optimal support.

The Use of Birth Ball as A Non-Pharmacological Complementary Therapy in The Reduction of Labor Pain in Phase 1

Childbirth is the process of expelling the fetus to the placenta, the process of giving birth is identical to pain, while to reduce this pain, non-pharmacological methods are carried out, one of which is the Birth Ball method. This study aims to evaluate the effectiveness of using birth ball as a non-pharmacological complementary therapy in reducing labor pain in the first stage. The method used was a narrative literature review by searching for relevant articles on Google Scholar using keywords such as “Birth ball” and “Labor pain”. Inclusion criteria included Indonesian-language articles published between 2021-2023. Of the six studies analyzed, it was found that birth ball use significantly reduced the intensity of labor pain. These studies showed that birth balls can accelerate cervical opening and reduce anxiety of laboring mothers through movements that increase endorphin release. In conclusion, birth balls are effective as an alternative method to reduce labor pain in Stage I, providing the added benefit of increasing maternal comfort and relaxation during the labor process. This study suggests the use of birth ball as part of midwifery practice to reduce labor pain non-pharmacologically.

Labour process theory and research on the changing nature of work and employment in China

China has undergone profound social and economic transformations over the last four decades. Deeply influenced by globalisation and capital-oriented marketisation, China has transitioned from a planned economy under state socialism to a market economy integrated into the global economy. As China becomes the ‘world’s workshop’, it has also experienced rapid industrialisation, the transformation of work and employment, and the reformation of the Chinese working class. Based on a review of the engagement of labour process theory (LPT) in China labour studies, this article suggests that the LTP has provided important insights and a theoretical framework for scholars to understand the empirical reality of the changing nature of work and employment in China in the reform era. The LPT’s capacity to connect the workplace to a broader political economy has allowed it to continue to expand its scope of analysis and engage with new developments and emerging issues in the Chinese workplace, such as the rise of digital platform labour, informal and precarious work, and workplace regimes in global value chains. Meanwhile, China labour scholars have made important contributions to the LPT by adapting it to the Chinese context and theorising the Chinese experience. Through a workplace-based approach, China labour scholars have theorised the role of the Chinese central and local states in shaping various factory regimes, expanded on Chinese workers’ diverse subjectivities in research on labour process, and developed new concepts such as the ‘dormitory labour regime’ that connects productive and social reproductive spheres.

What is the authentic underlying reason of childbirth worries in Turkish population?: An observational study.

This study aims to determine women's childbirth worries during antenatal. The research was carried out with 532 pregnant women in the antenatal clinic in Turkey as an observational study. Sociodemographic characteristics and scores of the Oxford Worries about Labor Scale of pregnant women were evaluated quantitatively. In addition, the answers given by the pregnant women to the open-ended question were themed. Although working status and receiving antenatal education reduce the fear of childbirth, birth scenes/stories on TV or social media, birth stories in the pregnant women's friends/family, being stressed in daily life, and dysmenorrhea increase the worries about childbirth (WaC). In addition, primiparas experience more WaC than multiparas. The reasons for WaC in pregnant women were classified as birth pain, artificial pain, cesarean section/receiving anesthesia, intervention/examination, pandemic, people's thoughts/experiences, birth process/insufficiency in birth, hospital/staff, fears about the baby, complications/death, and ignorance of the birth process. The results of this study reveal that WaC is a pivotal issue for pregnant women, for which managing the labor process, labor pain and labor fear is important. The stipulation of support for pregnant women is essential to enhance labor outcomes.

Marine pilots and the choreographic work of seaport mobilities

Research on cargomobilities has emphasised containerisation, algorithmic management, and the cost-driven calculus of logistics firms. Less visible is the necessary human labour that coordinates cargomobilities in challenging environments—for example, those workers who manoeuvre ships at seaports. In response, we take to the water to learn how ports function as spaces of everyday mobilities work. We follow a day in the working life of marine pilots—a specialist, locally-based workforce who board foreign-flagged ships to dock them safely. Their labour process is, we argue, a form of choreography: executing motions in correspondence with other workers, infrastructures, vessels, and environmental forces. Increasingly volatile oceanic conditions require technical knowledge of ships and guiding equipment, plus deep place-based knowledge of port idiosyncrasies and responsiveness to elemental forces—working with rather than against swell and wind, tides, channels, and weather. While global shipping becomes ever more cutthroat in pursuit of efficiencies, marine pilots choreograph mobilities with respect for earthly forces and the bulk and power of ships and seas, and thus perform the necessary infrastructural labour that offsets risk. Amidst worsening environmental hazards, we offer choreography as an analytical frame to centre the work, workers, collaboration, and more-than-human interactions underpinning mobilities.

Effectivity of Walking Epidural Analgesia in Normal Labor to Reduce Labor Pain and Improve Neonatal Outcome

Background: In Indonesia itself, only 15% of 2,700 labor women felt the pain was tolerable, meanwhile 85% said the pain was moderate until unbearable. Usage of epidural anaesthesia for pain relief in labor is common but controversies still persist about its effect and side effect on labor process. Neuraxial block especially epidural also not yet well known in Indonesia.Objective: This research aims to study maternal visual analogue scale (VAS) score changes before and after walking epidural anesthesia (WELA) and fetal outcome after birth. Methods: This research is an experimental design with one pre-test and post-test group. Data was taken from Unggul Karsa Medika Hospital and Permata Hati Clinic medical records from 2017 until 2022. Ethical approval was approved by Unggul Karsa Medika Hospital Ethical Committee (003/KEP-LIT/III/2023). After that all of 450 patients’ data was then analyzed by Wilcoxon with IBM® SPSS Statistic 26th with α=0.05.Result: Statistical analysis shows there was significant decrease of pain severity with initial VAS 7.58 to 3.37 after WELA procedure (p 0.0001). APGAR scores of all the foetus were normal with no asphyxia present.Conclusion: Our findings demonstrate the benefit of WELA for both of mother and fetus. was significantly decrease in VAS score during labor. Fetal outcome was also notably great after labour process and usage of epidural could decrease the risk of fetal acidemia and distress which reduce caesarean section rate. Usage of WELA in Indonesia could be encourage and recommended as an alternative to elective caesarean section.

Determinants of Higher Oxytocin Dose Need During Labor Induction

Background: Several guidelines have been published regarding intrapartum oxytocin infusion for labor induction or augmentation; however, many of them lack specificity. Objectives: Therefore, this study aimed to assess the oxytocin dose administered during labor and evaluate its association with maternal characteristics and short-term perinatal outcomes. Methods: This retrospective cross-sectional study was conducted on 162 term pregnant women who were admitted to the labor ward for vaginal delivery in two academic hospitals during 2021 - 2022. Maternal demographic features, obstetric and medical history data, labor process details (initial Bishop score, membrane status on admission and at the time of labor induction or augmentation, latent and active phase duration, oxytocin dose, delivery mode, and neonatal outcomes) were obtained and recorded. Participants were divided into two main groups based on the intrapartum oxytocin dose, and the desired outcomes were reported and compared between the groups. Results: The median maternal age was 28 years (range: 16 - 46). The median oxytocin dose administered during labor induction was 10 mU/min (range: 2.5 - 25 mU/min). Oxytocin dose was significantly correlated with gestational age (P < 0.001), cervical dilation and effacement (P < 0.001), fetal head station (P < 0.001), cervical consistency (P < 0.001), and cervical Bishop score before labor induction (P < 0.001). The cervical dilation at the time of membrane rupture was also positively correlated with the intrapartum oxytocin dose (P = 0.013). Higher gestational age was correlated with a higher required oxytocin dose (P < 0.001). The cesarean rate was 22.8% in the study population, and it was positively correlated with intrapartum oxytocin dose (P < 0.001). Conclusions: The cervical Bishop score and its components, except for cervical position, were correlated with the intrapartum oxytocin dose. In other words, the less favorable the cervix, the higher the likelihood of requiring higher doses of oxytocin and consequently experiencing a longer duration of labor. Additionally, the cesarean rate was higher in those who needed oxytocin doses of more than 10 mU/min; however, short - term neonatal outcomes were not different.

Narative Review The Effect of Endorphin Massage and Counter Pressure During Labor On Endorphin Hormone Release

Background: Labor pain is a subjective experience associated with uterine contractions, stretching of the cervix, and descent of the fetal head. According to the World Health Organization (WHO), every year, 210 million pregnancies occur in the world, and 20 million women experience pain due to childbirth. Of the 2700 mothers giving birth, 30% experienced severe pain, 20% of labor was accompanied by very severe pain, and 15% experienced mild pain. Non-pharmacological therapy continues to be developed in the world of obstetrics, which aims to provide comfort during the birthing process. Endorphin massage and counter pressure are non-pharmacological therapies that can stimulate the release of endorphins and reduce pain and anxiety during childbirth. Objective: This study aims to determine the effect of endorphin massage and counter pressure during labor on the release of endorphin hormones and their benefits. Methods: This research method was a literature review study. Journal searches were carried out by applying online databases such as PubMed, Garuda Portal, ScienceDirect, and Google Scholar. Articles were selected based on inclusion and exclusion criteria. Results: The analysis was carried out on 32 research articles. It was found that endorphin massage and counter pressure are non-pharmacological techniques to overcome and reduce labor pain and anxiety through the help of endorphin hormones which are useful for a smooth delivery process. Conclusion: The influence of endorphin massage and counter pressure during labor on the release of endorphin hormones, which are useful for reducing labor pain, reducing anxiety, increasing comfort, and speeding up the labor process.

EFEKTIVITAS SENAM HAMIL PADA IBU TRIMESTER III TERHADAP JENIS PERSALINAN

One of the causes of the high number of maternal deaths is prolonged labor. The form of prevention of prolonged labor that can be done is by controlling the five factors of the birth process which include power, passage, passenger psychology and helpers. Power is a very important birth factor, originating from pregnant women which can be controlled with pregnancy exercises. This research aim is to determine the outcomes of maternal exercise in the third trimester during the birth process. This research method is retrospective, with a total sampling technique of 25 and data analysis use Chi Square. The results of this study were that the majority of pregnant women in the third trimester did regular pregnancy exercise, with as 20 respondents (80.0%). Pregnant women in the third trimester who do pregnancy exercises regularly mostly have a normal delivery process, 17 respondents (85%), and the Pearson Chi-Square Test shows that the significant value is p value = 0.035 < a (0.05), so H1 is accepted. Keywords: Labor Process; Pregnancy Exercise Outcomes; Third Trimester

Designing a Midwife-Led Birth Center Program Based on the MAP-IT Model: A Sequential Explanatory Mixed-Methods Study

BackgroundIn recent decades, medical supervision of the labor and delivery process has expanded beyond its boundaries to the extent that in many settings, childbirth has become a medical event. This situation has influenced midwifery care. One of the significant barriers to midwives providing care to pregnant women is the medicalization of childbirth. So far, the policies and programs of the Ministry of Health to reduce medical interventions and cesarean section rates have not been successful. Therefore, the current study aims to be conducted with the purpose of “Designing a Midwife-Led Birth Center Program Based on the MAP-IT Model”.Methods/designThe current study is a mixed-methods sequential explanatory design by using the MAP-IT model includes 5 steps: Mobilize, Assess, Plan, Implement, and Track, providing a framework for planning and evaluating public health interventions in a community. It will be implemented in three stages: The first phase of the research will be a cross-sectional descriptive study to determine the attitudes and preferences towards establishing a midwifery-led birthing center focusing on midwives and women of childbearing age by using two researcher-made questionnaires to assess the participants’ attitudes and preferences toward establishing a midwifery-led birthing center. Subsequently, extreme cases will be selected based on the participants’ average attitude scores toward establishing a midwifery-led birthing center in the quantitative section. In the second stage of the study, qualitative in-depth interviews will be conducted with the identified extreme cases from the first quantitative phase and other stakeholders (the first and second steps of the MAP-IT model, namely identifying and forming a stakeholder coalition, and assessing community resources and real needs). In this stage, the conventional qualitative content analysis approach will be used. Subsequently, based on the quantitative and qualitative data obtained up to this stage, a midwifery-led birthing center program based on the third step of the MAP-IT model, namely Plan, will be developed and validated using the Delphi method.DiscussionThis is the first study that uses a mixed-method approach for designing a midwife-led maternity care program based on the MAP-IT model. This study will fill the research gap in the field of improving midwife-led maternity care and designing a program based on the needs of a large group of pregnant mothers. We hope this program facilitates improved eligibility of midwifery to continue care to manage and improve their health easily and affordably.Ethical codeIR.MUMS.NURSE.REC. 1403. 014.

Labor patterns of spontaneous first-stage labor in Chinese women with normal neonatal outcomes.

Friedman's standards, developed almost 50 years ago, may no longer align with the needs of today's obstetric population and current pregnancy management practices. This study aims to analyze contemporary labor patterns and estimate labor duration in China, focusing on first-stage labor data from Chinese parturients with a spontaneous onset of labor. This retrospective observational study utilized data from electronic medical records of a tertiary hospital in Changsha, Hunan. Out of a total of 2,689 parturients, exclusions were made for multiple gestations, preterm, post-term, or stillbirth, cesarean delivery, non-vertex presentation, and neonatal intensive care unit admission. Average labor curves were constructed by parity using repeated-measure analysis, and labor duration was estimated through interval-censored regression, stratified by cervical dilation at admission. We performed an analysis to assess the impact of oxytocin augmentation and amniotomy on labor progression and conducted a sensitivity analysis using women with complicated outcomes. Nulliparous women take over 180 minutes for cervical dilation from 3 to 4 cm, and the duration from 5 to 6 cm exceeds 145 minutes. Multiparous women experience shorter labor durations than nulliparous. Labor acceleration is observed after 5 cm in nulliparous, but no distinct inflection point is evident in the average labor curve. In the second stage of labor, the 95th percentile for nulliparous, with and without epidural analgesia, is 142 minutes and 127 minutes, respectively. These findings provide valuable insights for the reassessment of labor and delivery processes in contemporary obstetric populations, including current Chinese obstetric practice.
