Abstract
Pregnancies following previous caesarean section (CS) are associated with higher incidence of infections, postpartum haemorrhage and obstetric complications. The present study aimed to explore the effect of previous CS on reproductive, maternal and neonatal outcomes in women who underwent assisted reproductive techniques (ART). A systematic review and meta-analysis were conducted to assess reproductive and pregnancy outcomes following ART in women with and without a previous CS. Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed. Eligible language articles written in English, published up to October 2023, were identified in Medline, Google Scholar and Science Direct databases. The quality of the included studies was assessed using the Newcastle Ottawa Scale. A total of 19 articles, reporting on 13 different outcomes met the inclusion criteria. It was revealed that women with previous CS had 9% lower clinical pregnancy rates, 13% lower live birth rates, 11% lower implantation rates and 28% lower multiple pregnancy rates compared with women who had prior natural vaginal deliveries. Additionally, previous CS was associated with an 8-fold higher risk of difficult embryo transfers. No significant differences were noted in ectopic pregnancy rates, miscarriage rates or biochemical pregnancy rates. The present systematic review and meta-analysis demonstrated that previous CS is associated with decreased prospects of clinical pregnancy, live birth and successful embryo implantation during ART. The findings of the present study underscored the need to counsel women with prior CS regarding its potential impact on ART outcomes.

Am J Obstet Gynecol 2024; 230:667.e1-667.e21. [PMID: 37863159 DOI: 10.1016/j.ajog.2023.10.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 10/09/2023] [Accepted: 10/15/2023] [Indexed: 10/22/2023]
Abstract
BACKGROUND Previous studies have found that women who undergo cesarean delivery have fewer pregnancies. Cesarean delivery is also more common among women with lower fecundability. The potential role of cesarean delivery in reduced fecundability is not known. OBJECTIVE This study aimed to assess the bidirectional relationship between cesarean delivery and fecundability. STUDY DESIGN This was a prospective cohort study based on data from the Norwegian Mother, Father, and Child Cohort study linked with the Medical Birth Registry of Norway. We estimated the fecundability ratio (per cycle probability of pregnancy) and relative risk of infertility (time to pregnancy ≥12 months) by mode of delivery in the previous delivery among 42,379 women. For the reverse association, we estimated the relative risk of having a cesarean delivery by fecundability (the number of cycles women needed to conceive) among 74,024 women. RESULTS The proportion of women with infertility was 7.3% (2707/37,226) among women with a previous vaginal delivery and 9.9% (508/5153) among women with a previous cesarean delivery, yielding an adjusted relative risk of 1.21 (95% confidence interval, 1.10-1.33). Women with a previous cesarean delivery also had a lower fecundability ratio (0.90; 95% confidence interval, 0.88-0.93) than women with a previous vaginal delivery. When assessing the reverse association between fecundability and cesarean delivery, we found that women who did not conceive within 12 or more cycles had a higher risk for cesarean delivery (adjusted relative risk, 1.57; 95% confidence interval, 1.48-1.66) than women who conceived within the first 2 cycles. The associations remained after controlling for sociodemographic and clinical risk factors and were observed across parity groups. CONCLUSION Among women with more than 1 child, those who had a previous cesarean delivery subsequently had a lower fecundability ratio and an increased infertility risk than those who had a vaginal delivery. However, women who needed a longer time to conceive were also more prone to be delivered by cesarean delivery, indicating a bidirectional relationship between cesarean delivery and fecundability. This could suggest a common underlying explanatory mechanism and that the surgical procedure itself may not or only partly directly influence fecundability.

Abstract
OBJECTIVE This study was conducted to investigate the impact of previous delivery mode on pregnancy outcomes in patients with secondary infertility after frozen-thawed embryo transfer. METHODS This prospective observational study included 140 patients experiencing secondary infertility. Of these, 70 patients had a previous cesarean delivery (CD), while the remaining 70 patients had a previous normal vaginal delivery (NVD). The primary outcome was the implantation rate. The secondary outcomes included rates of clinical pregnancy, chemical pregnancy, miscarriage, and ectopic pregnancy. RESULTS The comparison of all fertility outcomes between the two groups revealed no statistically significant differences. The implantation rate was 40.4% in the CD group and 41.7% in the NVD group (p=0.842). The clinical pregnancy rate was 50% in the CD group and 49.3% in the NVD group (p=0.932), while the chemical pregnancy rate was 14.6% in the CD group and 19% in the NVD group (p=0.591). The miscarriage rates in the CD and NVD groups were 20% and 17.6%, respectively (p=0.803). One case of tubal ectopic pregnancy occurred in the NVD group (1.4%). CONCLUSION The mode of prior delivery did not significantly impact pregnancy outcomes following frozen-thawed embryo transfer.

Abstract
Delivery by cesarean section is a surgical procedure of delivery to a newborn baby, and the process is applied when vaginal delivery is unsafe. This study aims to identify the socioeconomic, demographic, and cultural factors that significantly impact the delivery by caesarean section. The 2019 Ethiopia Mini Demographic and Health Survey (2019 EMDHS) data were used to conduct this research, and this study considered 2872 ever-married women all over the country who delivered in the clinical setting. Firstly, a frequency distribution table has been constructed to understand the characteristics of the selected explanatory and study variables. Then Chi-square test identifies the association between various socioeconomic and demographic factors and delivery by the caesarian section. Finally, the Binary Logistic Regression was used to determine the factors that substantially impact the caesarian section among women in Ethiopia. The Chi-square test of association showed that mother's age, type of residence, highest education level, religion, socioeconomic status, total children ever born, use of contraception, age of mothers at first birth, and preceding birth interval were significantly associated with the caesarian section. The multivariate binary logistic regression analysis revealed that the mother's current age (Age Group: 31-40; Odds Ratio: 2.487, p<0.05) and religion (Muslim; Odds Ratio: 0.599, p<0.05) substantially influenced the study feature. Moreover, the highest educational level (Secondary and higher; Odds Ratio: 1.581, p<0.05), and the preceding birth interval (>40 months; Odds Ratio: 0.682, p<0.05) were also found to have considerable impacts on the caesarian section. Furthermore, the total number of children ever born (>5; Odds Ratio: 0.498, p<0.05) significantly impacts the delivery by caesarean section in Ethiopia. This study's results would be useful to policymakers to take necessary steps to reduce unnecessary delivery by caesarian section and ensure a safer newborn delivery process.

Effects of short birth interval on different forms of child mortality in Bangladesh: Application of propensity score matching technique with inverse probability of treatment weighting. PLoS One 2023; 18:e0284776. [PMID: 37083714 PMCID: PMC10121045 DOI: 10.1371/journal.pone.0284776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 04/07/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND The prevalence of Short Birth Interval (SBI) is higher in Low- and Middle-Income countries (LMICs), including Bangladesh. Previous studies in LMICs have estimated the effects of SBI on child mortality by comparing two unequal groups of mothers based on their socio-economic status. This approach may lead to overestimation or underestimation of the true effect of birth interval on child mortality, particularly when sample sizes are relatively small. OBJECTIVE We determined the effects of SBI on several forms of child mortality in Bangladesh by comparing two equal groups created by applying the propensity score matching technique. METHODS This study analyzed data from 5,941 mothers and 1,594 health facilities extracted from the 2017/18 Bangladesh Demographic and Health Survey and the 2017 Bangladesh Health Facility Survey. The exposure variable was SBI (defined as the interval between two subsequent births <33 months: yes, no), while the outcome variables were neonatal mortality (defined as mortality within 28 days of birth: yes, no), infant mortality (defined as mortality within 1 year of birth: yes, no), and under-five mortality (defined as mortality within 5 years of birth: yes, no). Multilevel Poisson regression based on inverse probability treatment weights was used to determine the association between exposure and outcome variables. RESULTS The prevalence rates of neonatal, infant, and under-five mortality were 48.8, 30.8, and 23.1 per 1000 live births, respectively. Newborns of SBI mothers were found to have a 63% higher likelihood of neonatal mortality (aPR, 1.63; 95% CI, 1.08-2.46) compared to newborns of non-SBI mothers. Furthermore, the prevalence of infant mortality and under-five mortality was 1.45 times higher (aPR, 1.45; 95% CI, 1.01-2.08) and 2.82 times higher (aPR, 2.82; 95% CI, 2.16-3.70), respectively, among babies born in a short interval of their immediately preceding sibling as compared to babies born in a normal interval of their immediately preceding sibling. CONCLUSIONS Findings of this study indicate that SBI is an important predictor of child mortality. Consequently, around 1 million children born in a short interval every year in Bangladesh are at risk of dying before reaching their fifth birthday. This indicates a challenge for Bangladesh to achieve the SDG 3 target to reduce neonatal and under-five mortality to 12 and 25 deaths per 1000 live births, respectively. Hence, awareness-building programs about the adverse effects of SBI and strengthening existing healthcare facilities are important.

Abstract
INTRODUCTION In the attempt of a trial of labor after a cesarean section approximately one in 200 women experience a complete uterine rupture. As a complete uterine rupture is associated with an adverse perinatal outcome, data regarding subsequent pregnancies are needed to provide proper care and guidance to women with a complete uterine rupture when informing them of future possibilities. The objective of this study was to investigate the fetal and maternal outcomes in subsequent pregnancies after a complete uterine rupture. MATERIAL AND METHODS Retrospective population-based case-control study. Denmark 1997-2017. A total of 175 women with complete uterine rupture during an attempted trial of labor after cesarean (TOLAC) at term (cases) and a corresponding group of 272 women with no uterine rupture during an attempted TOLAC at term (controls) were labeled as index deliveries. Index deliveries were included from January 1, 1997 to December 31, 2008. From the date of the index delivery to December 31, 2017 the information on subsequent pregnancies and deliveries, and on referral to hospital with any obstetric or gynecological diagnosis were retrieved from the Danish Medical Birth Registry and National Patient Registry. Main outcome measures were miscarriage, perinatal death, neonatal morbidity, preterm birth, and recurrence of uterine rupture. Outcome measures were compared between cases and controls. RESULTS After the index deliveries; there were 109 pregnancies and 70 deliveries after gestational age 22+0 weeks in the population of cases. In the population of controls, there were 183 pregnancies and 126 deliveries after 22+0 weeks. Cases had a significantly higher risk of miscarriage (odds ratio [OR] 3.99; 95% confidence interval [CI] 1.36-13.17). The incidence of uterine rupture was 8.6% among cases and 0.8% among controls (OR 11.7; 95% CI 1.36-543.1). Among cases, 98.6% had live-born infants, and none of these had severe neonatal morbidity. No significant association was found between previous complete uterine rupture and preterm delivery, placenta previa, hysterectomy in relation to subsequent births, diagnosis such as meno/metrorrhagia, dysmenorrhea, or procedures such as hysteroscopy or hysterectomy. CONCLUSIONS In pregnancies following complete uterine rupture continuing after 22+0 weeks, maternal and fetal outcomes are good when managed promptly with cesarean delivery.

Abstract
AbstractThe aim of this study was to explore whether the presence of intra-cavitary fluid (ICF) influences the pregnancy outcomes of patients with caesarean section (CS) in embryo transfer cycles. A total of 8494 transferred cycles of 4924 women were enrolled in this retrospective study and separated into three subgroups by previous delivery method and the presence of intra-cavity fluid, a caesarean group with ICF (CS-ICF, n = 649), a caesarean group without ICF (CS-noICF, n = 3207), and the remaining 4638 cycles without ICF were included in the vaginal delivered group (VD, n = 4638). Baseline characteristics and clinical outcome were compared. Propensity score matching (PSM) was conducted to adjust confounding factors between groups. Patients in the CS-ICF group were of younger age (36.49 ± 4.19 vs 37.34 ± 4.25, 37.32 ± 4.86, P < 0.001), had better ovary reserve, and had more blastocyst transferred compared with the CS-noICF and VD groups. However, cycles in the CS-ICF group achieved unsatisfactory clinical pregnancy outcomes. PSM analysis for comparability and differences in clinical outcomes still existed. The clinical pregnancy rate was significantly lower in the CS-ICF group than in the CS-noICF group (35.1% vs 41.7% for CS-noICF group, 48.1% for VD group, P < 0.001). Subgroup analysis of fresh embryo transferred cycles, the differences in clinical outcomes disappeared after PSM analysis, while the clinical pregnancy rate was still lowest among the three matched groups of FET cycles (36.4% vs 50.3% for VD group, P < 0.001). The presence of intra-cavitary fluid (ICF), but not necessarily the isthmocele, significantly compromises the clinical pregnancy rate in patients with previous CS undergoing IVF/ICSI treatment.

Abstract
Background Delayed childbearing has been noted in a high percentage of women with a previous Caesarean section (CS). Many women with CS scar defects (CSDs) present with clinical symptoms of irregular vaginal bleeding. The present study aimed to investigate bacterial colonies at CSDs in women suffering from secondary infertility. Methods This observational study included 363 women with secondary infertility who visited the Assisted Reproduction Unit between 2008 and 2013. Among them, 172 women with a previous CS and 191 women with no previous CS were approached. The women with a previous CS had their CS operations in the past 1 to 14 years, with a mean of 3.5 years. The presence of CSDs was detected by vaginal ultrasonography. Bacteriology cultures of specimens taken from the uterine niches in those with CSDs were collected during Day 7 to Day 10 of the follicular phase. Specimens were obtained from the endocervical canal for bacterial culture in those without CSDs. The main outcome measure was the detection of the growth of bacterial colonies. Results CSDs were found in 60.4% (96 of 159) of women with a previous CS. In women with a previous CS, bacterial colonies were identified in 89.6% (86 of 96) and 69.8% (44 of 63) of women with and without CSDs, respectively. In women with no previous CS, 49.7% (88 out of 177) of bacterial cultures of endocervical samples showed bacterial colony growth. Gram-positive cocci (P = 0.0017, odds ratio (OR) = 1.576, 95% confidence intervals (CI) -22.5 to − 5.4) and Gram-negative rods (P = 0.0016, OR = 1.74, CI − 20.8 to − 5.0) were the most commonly isolated bacteria and contributed to approximately 90% of all microorganisms found in those with a previous CS. In women with a previous CS, more Gram-negative rods were isolated (P = 0.01, OR = 1.765, CI − 27.2 to − 3.8), especially Pseudomonas species (P = 0.02, OR = 1.97, CI − 16.7 to − 1.0), in those with visible CSDs than in those without CSDs. Conclusions Bacterial colonization at CSDs was found in a high percentage of women with secondary infertility.

Novel laparoscopic surgery for the repair of cesarean scar defect without processing scar resection. BMC Pregnancy Childbirth 2021; 21:815. [PMID: 34879840 PMCID: PMC8653604 DOI: 10.1186/s12884-021-04281-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 11/22/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Cesarean scar defect (CSD), especially CSD with residual myometrium less than 3 mm is reported to be the highest risk agent associated with uterine rupture for subsequent pregnancy. Currently, laparoscopic resection and suture was the mainstay therapy method for CSD with a residual myometrium less than 3 mm in women with a desire to conceive. Besides, the women have CSD related symptoms, especially postmenstrual bleeding, should be recommended for CSD treatment. This study is to investigate the efficiency of this novel laparoscopic surgery for the repair of cesarean scar defect (CSD) without scar resection for residual myometrium thickening. METHOD This retrospective clinical study enrolled 76 women diagnosed with CSD who had a residual myometrium thickness less than 3 mm and also had a desire to conceive, had undergone laparoscopic surgery for the repair of CSD in the time period March 2016 to March 2018. Two study cohorts were created among the 76 patients: 40 patients had undergone the novel laparoscopic repair of CSD without processing scar resection (Group A), whereas 36 patients had undergone the traditional laparoscopic resection and suture of CSD (Group B). RESULTS Residual myometrium thickening occurred among all the 76 patients and the average residual myometrium thickness was increased to almost 6 mm, presenting no between-group difference. In Group A, all the CSD-related postmenstrual bleeding was resolved or improved, but one patient in Group B has no obvious change to postmenstrual bleeding. After CSD repair, 20 patients got pregnant naturally in Group A, and there was no cesarean scar pregnancy and uterine rupture. While, there were 9 cases of natural pregnancy in Group B. No uterine rupture occurred among these 9 pregnant women of Group B, but 1 case of pregnancy was terminated due to cesarean scar pregnancy. CONCLUSION Laparoscopic repair without processing scar resection seems to be a feasible, safe and simple operative approach for CSD treatment, which can thicken residual myometrium and improve postmenstrual bleeding.

Abstract
Objective The aim of this study was to report on the rates of obstetric interventions within each hospital jurisdiction in the state of Queensland, Australia. Methods This project used a whole-of-population linked dataset that included the health and cost data of all mothers who gave birth in Queensland, Australia, between 2012 and 2015 (n=186789), plus their babies (n=189909). Adjusted and unadjusted rates of obstetric interventions and non-instrumental vaginal delivery were reported within each hospital jurisdiction in Queensland. Results High rates of obstetric intervention exist in both the private and public sectors, with higher rates demonstrated in the private than public sector. Within the public sector, there is substantial variation in rates of intervention between hospital and health service jurisdictions after adjusting for confounding variables that influence the need for obstetric intervention. Conclusions Due to the high rates of obstetric interventions statewide, a deeper understanding is needed of what factors may be driving these high rates at the health service level, with a focus on the clinical necessity of the provision of Caesarean sections. What is known about the topic? Variation in clinical practice exists in many health disciplines, including obstetric care. Variation in obstetric practice exists between subpopulation groups and between states and territories in Australia. What does this paper add? What we know from this microlevel analysis of obstetric intervention provision within the Australian population is that the provision of obstetric intervention varies substantially between public sector hospital and health services and that this variation is not wholly attributable to clinical or demographic factors of mothers. What are the implications for practitioners? Individual health service providers need to examine the factors that may be driving high rates of Caesarean sections within their institution, with a focus on the clinical necessity of Caesarean section.

[PMID: 32700808 DOI: 10.1111/ppe.12702] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 04/09/2020] [Accepted: 05/03/2020] [Indexed: 12/01/2022]
Abstract
BACKGROUND Little is known about the influence of the post-partum interval-defined as the time between giving birth and attempting to conceive again-on subsequent fecundability. OBJECTIVES We evaluated the association between the post-partum interval and fecundability in Pregnancy Study Online (PRESTO), a web-based prospective preconception cohort of pregnancy planners from the United States and Canada. METHODS Eligible women were aged 21-45 years, attempting pregnancy, and not using fertility treatment. Women completed a baseline questionnaire to ascertain information on demographics, life style factors, and reproductive history, including detailed information on all previous pregnancies. They completed bi-monthly follow-up questionnaires for up to 12 months to update pregnancy status over time. We used proportional probabilities regression models to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs) adjusted for sociodemographic and reproductive history covariates. Analyses were restricted to multiparous women who had been attempting pregnancy with the same male partner for ≤6 menstrual cycles at enrolment. RESULTS During 2013-2019, 1489 female participants contributed 959 pregnancies and 5003 cycles. The median post-partum interval was 18 months. Compared with a 12- to 23-month post-partum interval, FRs for post-partum intervals of <12, 24-47, and ≥48 months were 0.89 (95% CI 0.77, 1.04), 1.06 (95% CI 0.91, 1.23), and 0.81 (95% CI 0.62, 1.05), respectively. When restricting to women without a history of subfertility, results were consistent for long post-partum interval and attenuated for short post-partum interval. CONCLUSIONS Among North American pregnancy planners, long post-partum intervals (≥48 months) were associated with slightly reduced fecundability. Short post-partum intervals (<12 months) were weakly associated with reduced fecundability in some subgroups including women with a history of caesarean delivery and planned pregnancies.

Abstract
This meta-analysis investigated whether a previous Caesarean section has an impact on the outcomes of treatment with assisted reproductive technology (ART). PubMed, Embase, Cochrane Library, Web of Science and Google Scholar were searched. Clinical trials published in English up to May 2020 were included. Seven studies performed between 2016 and 2020 met all the inclusion criteria. It was found that previous Caesarean section leads to significantly decreased clinical pregnancy rate (CPR) (risk ratio [RR] 0.86; 95% confidence interval [CI], 0.81, 0.92; P < 0.00001) and live birth rate (LBR) (RR 0.80; 95% CI 0.73, 0.86; P < 0.00001). Caesarean section increased the miscarriage rate (RR 1.39; 95% CI 1.18, 1.64; P < 0.0001), and difficult transfer (RR 8.23; 95% CI 4.63, 14.65; P < 0.00001) after ART compared with women who had previous vaginal delivery. The combined results also showed similar endometrial thickness, number of oocytes retrieved, implantation rate, ectopic pregnancy rate, preterm birth and stillbirth between women with previous Caesarean section and women with previous vaginal delivery. In conclusion, Caesarean sections have a detrimental effect on CPR and LBR, and increase the risk of miscarriage and difficult transfer. The indications for Caesarean section should be strictly controlled, and full consultation should be provided to pregnant women. Further studies with stratification analysis of twin and single pregnancies are needed to evaluate the impact of Caesarean section.

Abstract
Background Iran has ranked second in the frequency of cesarean delivery (CD) and this rate in 2014 has increased by 56 percent. The CD has multiple complications for the woman and newborn, and due to the women's readmission after surgery impose additional costs to the countries. Although CD has many complications and is not recommended by obstetrician and midwives; some factors affect the choice of this method of delivery. Methods We used data from the Iranian Institute for Health Sciences Research (IIHSR) in 2015. We studied the effects of factors such as socioeconomic and demographic factors and supplemental insurance status in the choice of CD. We used multilevel Zero-Inflated models for the modeling of data. Results The employed women resident in urban areas with the high-income and age greater than 34-yr old and supplemental insurance more likely chose CD. On the other hand, women with high education level, women who use at least one media (e.g. Radio, television, etc.) and women that use contraceptive methods have chosen the less CD. Conclusion Our findings highlighted the importance of supplemental insurance and socio-economic status in choosing a CD by women. However, in some cases especially in the rich class of society, the high cost of this type of delivery does not affect the choice decrease of it, and governments should adopt rigorous policies in using this method.

Abstract
Despite the growing incidence of cesarean deliveries (CDs), procedure costs and benefits continue to be controversially discussed. In this study, we identify the effects of CDs on subsequent fertility and maternal labor supply by exploiting the fact that obstetricians are less likely to undertake CDs on weekends and public holidays and have a greater incentive to perform them on Fridays and days preceding public holidays. To do so, we adopt high-quality administrative data from Austria. Women giving birth on different days of the week are pre-treatment observationally identical. Our instrumental variable estimates show that a non-planned CD at parity 0 decreases lifecycle fertility by almost 13.6%. This reduction in fertility translates into a temporary increase in maternal employment.

Abstract
BACKGROUND Women's fertility intentions, their desired number of children and desired inter-pregnancy interval (IPI) are related to micro (personal) and macro (socio-cultural) level factors. We investigated factors that contribute to changes in women's fertility intentions in Israel, a developed country with high birth rates. METHODS Pregnant women (N = 1163), recruited from prenatal clinics and hospitals in two major metropolitan areas, completed self-report questionnaires prenatally (≥24 weeks gestation) and postpartum (2 months after childbirth). Women reported their socio-demographic background and obstetric history prenatally, their desired number of children and IPI at both time-points, and their objective and subjective birth experiences postpartum. RESULTS The findings indicated that background characteristics were related to prenatal fertility intentions. The strongest contributor to prenatal fertility intentions was women's degree of religiosity- the more religious they were, the more children they desired and the shorter their intended IPI. Women's postpartum fertility intentions were mostly consistent with their prenatal reports. In regression models, women who were very-religious, more educated and had previously given birth were less likely to report a lower number of desired of children at postpartum, compared to their prenatal report. Women who reported greater birth satisfaction and gave birth for the first time were less likely to change desired IPI. CONCLUSION Having a negative birth experience could adversely affect women's fertility intentions. Yet, in a pronatalist and medicalized birth culture, social pressures may decrease the effects of birth experiences on fertility intentions.

Abstract
IMPORTANCE More than 20% of births globally are by cesarean delivery, including more than 30% in the US. Prior studies have reported lower rates of childbearing after cesarean delivery, but it is not clear if this is due to maternal choice or lower conception rates. OBJECTIVE To investigate the association between mode of first delivery and subsequent conceptions and live births. DESIGN, SETTING, AND PARTICIPANTS The First Baby Study was a multicenter prospective cohort study of women aged 18 to 35 years with singleton pregnancies, enrolled and interviewed before first childbirth, who delivered in Pennsylvania from 2009 to 2011 and were followed up for 36 months after delivery (until April 2014). Data analysis for this study took place between May and July 2019 and in January 2020. EXPOSURES Mode of first delivery (cesarean or vaginal). MAIN OUTCOMES AND MEASURES Rates of subsequent conceptions and live births. Discrete-time Cox proportional hazard regression models were used to compare the rate of subsequent conception (vaginal vs cesarean) among those who completed the 36-month survey, accounting for reported months of unprotected intercourse during the follow-up period and adjusting for relevant covariates. A log binomial regression was used to compare the age-adjusted rate of subsequent live birth (vaginal vs cesarean) among those who completed the 36-month survey. RESULTS The study population consisted of 2423 women who were retained to the 36-month survey (mean [SD] age at baseline was 27.2 [4.4] years and 712 [29.4%] delivered by cesarean). There were 2046 women who had unprotected intercourse during the follow-up period, 2021 of whom provided data on months of unprotected intercourse. Cesarean delivery was associated with lower rates of conception after unprotected intercourse during the follow-up period (413 of 599 [68.9%]) compared with vaginal delivery (1090 of 1422 [76.7%]) (adjusted hazard ratio, 0.85; 95% CI, 0.74-0.96). Cesarean delivery was also associated with reduced likelihood of a subsequent live birth (305 women [42.8%]) compared with vaginal delivery (857 women [50.1%]), with an age-adjusted risk ratio of 0.83 (95% CI, 0.75-0.92). CONCLUSIONS AND RELEVANCE In the 3 years following first childbirth, women who delivered their first child by cesarean had lower rates of conception after unprotected intercourse, and fewer of these women had a second child than those who delivered vaginally.

Abstract
OBJECTIVE Previous systematic reviews have reported that cesarean birth is associated with reduced rate of subsequent fertility. However, other common mode of delivery was poorly understood. The aim of this study was to systematically investigate the subsequent fertility in patients having different modes of non-spontaneous vaginal delivery, if compared to normal vaginal delivery. STUDY DESIGNS Medline (via PubMed), Web of Science, Embase (via Dialog), CENTRAL (via Cochrane Library), ScienceDirect (via Elsevier) and ClinicalTrial.gov were searched up to October 2019, without language restrictions in this systematic review and meta-analysis. Articles assessing the mode of delivery and subsequent fertility were included. Quality assessment was evaluated using the nine-point Newcastle Ottawa Scale by two independent reviewers. RESULTS Twenty-one articles, including 4,423,544 women of reproductive age, were included. Results showed that women had a 9% (RR: 0.91 [95 %CI 0.88, 0.94]) lower probability of subsequent fertility in primary cesarean birth group, compared with spontaneous vaginal delivery. Further analysis discovered that a 13 % (0.87, [0.85, 0.90]) lower probability of subsequent fertility was observed in women delivered by emergency cesarean birth, a 14 % (0.86, [0.82, 0.91) lower probability by elective cesarean birth, a 39 % (0.61, [0.57, 0.66]) by maternal-requested cesarean birth, and a 2% (0.98, [0.97, 1.00]) by instrumental vaginal delivery. CONCLUSIONS Non-spontaneous vaginal delivery may be associated with lower probability of subsequent fertility. Decision makers and obstetricians should be cautious when choosing the mode of delivery.

Abstract
Background: The effect of maternal mental health during pregnancy on Cesarean section through implications of pre- and postnatal birth have narrowly been investigated. The aim of the present study was to investigate the effect of maternal mental health during pregnancy on the type of delivery in the suburbs of Bandar Abbas. Methods: This study used data of 200 mothers registered in a prospective cohort study on pregnant women in the suburbs of Bandar Abbas, South of Iran, during 2016-18. The presence of depression, anxiety, or stress in expecting mothers were measured by DASS-21 questionnaire and the outcome defined as having Cesarean section (Cesarean section) was measured at postpartum. The relative risk (95% CI) was calculated using Cox regression models. All analyses were performed using STATA statistical package, with a significance level of 5%. Results: Information of 196 mothers were collected (98% response rate); the mean age of the participants was 27.28 (±5.62) years. The prevalence of depression, anxiety, and stress was 13.8% (27), 40.4% (40), and 7.6% (15), respectively. Nearly 40% of mothers went through Cesarean section. Compared to mothers with good mental health, the risk of Cesarean section was 96% higher in depressed mothers (RR=2, 95% CI: 1.43-2.74) (p=0.001), 81% higher in anxious mothers (RR=1.81, 95% CI: 1.29-2.53) (p=0.003), and 75% higher in stressed mothers (RR=1.75, 95% CI: 0.86-3.56) (p=0.121). Conclusion: The findings of this study showed that poor mental health, especially anxiety and depression, during pregnancy could increase the risk of Cesarean section. Accordingly, screening protocols for mental health status and prenatal counseling sessions are suggested for pregnant mothers to increase their informed decision on types of delivery.

Abstract
Cesarean section (CS) is associated with maternal morbidity and mortality in developing countries. This study is conducted to assess factors associated with CS in Pakistan using partial least squares (PLS) algorithm, where categorical factors are modeled. Nationally representative maternal data from Pakistan Demographic and Health Surveys (PDHS) conducted during 2012-2013 is used in this study. Among correlation coefficient based PLS regression proposed algorithms for categorical factors, Pearson's Contingency Coefficient (CC) PLS coupled with loading weight (LW) appeared to be the most efficient method in terms of model performance and influential factor selection. Region of residence, type of place of residence, mother's and her partner's level of education, wealth index, year of birth, previous terminated pregnancy, use of contraception, prenatal care provided by a doctor and nurse/midwife/LHV (lady health visitor), assistance provided by a nurse/midwife/LHV,number of antenatal visits, size of child, antenatal care provided by government hospital, transport facility for medical care, baby birth status, mother's age at first birth, preceding birth interval and vaccination of hepatitis B-1 and B2 are found to be significantly affecting the CS delivery method. Correlation coefficient based PLS regression algorithms may serve more efficiently as a multivariate technique to treat high-dimensional categorical data.

Abstract
Background There is global concern for the overuse of obstetric interventions during labour and birth. Of particular concern is the increasing amount of mothers and babies experiencing morbidity and mortality associated with caesarean section compared to vaginal birth. In high-income settings, emerging evidence suggests that overuse of obstetric intervention is more prevalent among wealthier mothers with no medical need of it. In Australia, the rates of caesarean section and other obstetric interventions are rising. These rising rates of intervention have been mirrored by a decreasing rate of unassisted non-instrumental vaginal deliveries. In the context of rising global concern about rising caesarean section rates and the known health effects of caesarean section on mothers and children, we aim to better characterise the use of obstetric intervention in the state of Queensland, Australia by examining the characteristics of mothers receiving obstetric intervention. Identifying whether there is overuse of obstetric interventions within a population is critical to improving the quality, value and appropriateness of maternity care. Methods The association between demographic characteristics (at birth) and birth delivery type were compared with chi-square. The percentage of mothers based on their socioeconomic characteristics were reported and differences in percentages of obstetric interventions were compared. Multivariate analysis was undertaken using multiple logistic regression to assess the likelihood of receiving obstetric intervention and having a vaginal (non-instrumental) delivery after accounting for key clinical characteristics. Results Indigenous mothers, mothers in major cities and mothers in the wealthiest quintile all had higher percentages of all obstetric interventions and had the lowest percentages of unassisted (non-instrumental) vaginal births. These differences remained even after adjusting for other key sociodemographic and clinical characteristics. Conclusions Differences in obstetric practice exist between economic, ethnic and geographical groups of mothers that are not attributable to medical or lifestyle risk factors. These differences may reflect health system, organisational and structural conditions and therefore, a better understanding of the non-clinical factors that influence the supply and demand of obstetric interventions is required.

Abstract
A caesarean section (CS) can be a life-saving intervention when medically indicated, but this procedure can also lead to short-term and long-term health effects for women and children. Given the increasing use of CS, particularly without medical indication, an increased understanding of its health effects on women and children has become crucial, which we discuss in this Series paper. The prevalence of maternal mortality and maternal morbidity is higher after CS than after vaginal birth. CS is associated with an increased risk of uterine rupture, abnormal placentation, ectopic pregnancy, stillbirth, and preterm birth, and these risks increase in a dose-response manner. There is emerging evidence that babies born by CS have different hormonal, physical, bacterial, and medical exposures, and that these exposures can subtly alter neonatal physiology. Short-term risks of CS include altered immune development, an increased likelihood of allergy, atopy, and asthma, and reduced intestinal gut microbiome diversity. The persistence of these risks into later life is less well investigated, although an association between CS use and greater incidence of late childhood obesity and asthma are frequently reported. There are few studies that focus on the effects of CS on cognitive and educational outcomes. Understanding potential mechanisms that link CS with childhood outcomes, such as the role of the developing neonatal microbiome, has potential to inform novel strategies and research for optimising CS use and promote optimal physiological processes and development.

PLoS Med 2018; 15:e1002494. [PMID: 29360829 PMCID: PMC5779640 DOI: 10.1371/journal.pmed.1002494] [Citation(s) in RCA: 409] [Impact Index Per Article: 68.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 12/18/2017] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Cesarean birth rates continue to rise worldwide with recent (2016) reported rates of 24.5% in Western Europe, 32% in North America, and 41% in South America. The objective of this systematic review is to describe the long-term risks and benefits of cesarean delivery for mother, baby, and subsequent pregnancies. The primary maternal outcome was pelvic floor dysfunction, the primary baby outcome was asthma, and the primary subsequent pregnancy outcome was perinatal death. METHODS AND FINDINGS Medline, Embase, Cochrane, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were systematically searched for published studies in human subjects (last search 25 May 2017), supplemented by manual searches. Included studies were randomized controlled trials (RCTs) and large (more than 1,000 participants) prospective cohort studies with greater than or equal to one-year follow-up comparing outcomes of women delivering by cesarean delivery and by vaginal delivery. Two assessors screened 30,327 abstracts. Studies were graded for risk of bias by two assessors using the Scottish Intercollegiate Guideline Network (SIGN) Methodology Checklist and the Risk of Bias Assessment tool for Non-Randomized Studies. Results were pooled in fixed effects meta-analyses or in random effects models when significant heterogeneity was present (I2 ≥ 40%). One RCT and 79 cohort studies (all from high income countries) were included, involving 29,928,274 participants. Compared to vaginal delivery, cesarean delivery was associated with decreased risk of urinary incontinence, odds ratio (OR) 0.56 (95% CI 0.47 to 0.66; n = 58,900; 8 studies) and pelvic organ prolapse (OR 0.29, 0.17 to 0.51; n = 39,208; 2 studies). Children delivered by cesarean delivery had increased risk of asthma up to the age of 12 years (OR 1.21, 1.11 to 1.32; n = 887,960; 13 studies) and obesity up to the age of 5 years (OR 1.59, 1.33 to 1.90; n = 64,113; 6 studies). Pregnancy after cesarean delivery was associated with increased risk of miscarriage (OR 1.17, 1.03 to 1.32; n = 151,412; 4 studies) and stillbirth (OR 1.27, 1.15 to 1.40; n = 703,562; 8 studies), but not perinatal mortality (OR 1.11, 0.89 to 1.39; n = 91,429; 2 studies). Pregnancy following cesarean delivery was associated with increased risk of placenta previa (OR 1.74, 1.62 to 1.87; n = 7,101,692; 10 studies), placenta accreta (OR 2.95, 1.32 to 6.60; n = 705,108; 3 studies), and placental abruption (OR 1.38, 1.27 to 1.49; n = 5,667,160; 6 studies). This is a comprehensive review adhering to a registered protocol, and guidelines for the Meta-analysis of Observational Studies in Epidemiology were followed, but it is based on predominantly observational data, and in some meta-analyses, between-study heterogeneity is high; therefore, causation cannot be inferred and the results should be interpreted with caution. CONCLUSIONS When compared with vaginal delivery, cesarean delivery is associated with a reduced rate of urinary incontinence and pelvic organ prolapse, but this should be weighed against the association with increased risks for fertility, future pregnancy, and long-term childhood outcomes. This information could be valuable in counselling women on mode of delivery.

Abstract
Background In African countries, caesarean sections are usually performed to save mothers and babies’ lives, sometimes in extremis and at considerable costs. Little is known about the health and lives of women once discharged after such surgery. We investigated the long-term effects of life-saving caesarean section on health, economic and social outcomes in Burkina Faso. Methods We conducted a 4 year prospective cohort study of women and their babies using mixed methods. The quantitative sample was selected in seven hospitals and included 950 women: 100 women with a caesarean section associated with near-miss complication (life-saving caesareans); 173 women with a vaginal birth associated with near-miss complication; and 677 women with uncomplicated vaginal childbirth. Structured interviews were conducted at 3 months, 6 months, 12 months and 3 and 4 years postpartum. These were supplemented by medical record data on delivery and physical examinations at 6 and 12 months postpartum. The lives and experiences of 21 women were documented ethnographically. Data were analysed with multivariable logistic regressions, using survival analysis and thematic analysis. Results The physical effects of life-saving caesareans appeared to be similar to women who had an uncomplicated childbirth, although 55 % of women with life-saving caesareans had another caesarean in their next pregnancy. The negative effects were generally economic, social and reproductive when compared to vaginal births, including increased debts (AOR = 3.91 (1.46–10.48) and sexual violence (AOR = 4.71 (1.04–21.3)) and lower fertility (AOR = 0.44 (0.24–0.80)) 4 years after life-saving caesareans. In the short and medium term, women with life-saving caesareans appeared to suffer increased psychological distress compared to uncomplicated births. They were more likely to use contraceptives (AOR = 5.95 (1.53–23.06); 3 months). Mortality of the index child was increased in both near-miss groups, independent of delivery mode. Ethnographic data suggest that these consequences are significant for Burkinabe women, whose well-being and social standing are mostly determined by their fertility, marriage strength and family links. Conclusions Life-saving caesareans have broad consequences beyond clinical sequelae. The recent policy to subsidise emergency obstetric care costs implemented in Burkina Faso should help avoid the majority of catastrophic costs, shown to be problematic for women undergoing emergency caesarean section.

Abstract
Caesarean section (CS) is a common surgical procedure. Although it has been performed in a modern context for about 100 years, there is no concise analysis of the international architecture of caesarean section research output available so far. Therefore, the present study characterizes the global pattern of the related publications by using the NewQIS (New Quality and Quantity Indices in Science) platform, which combines scientometric methods with density equalizing mapping algorithms. The Web of Science was used as a database. 12,608 publications were identified that originated from 131 countries. The leading nations concerning research activity, overall citations and country-specific h-Index were the USA and the United Kingdom. Relation of the research activity to epidemiologic data indicated that Scandinavian countries including Sweden and Finland were leading the field, whereas, in relation to economic data, countries such as Israel and Ireland led. Semi-qualitative indices such as country-specific citation rates ranked Sweden, Norway and Finland in the top positions. International caesarean section research output continues to grow annually in an era where caesarean section rates increased dramatically over the past decades. With regard to increasing employment of scientometric indicators in performance assessment, these findings should provide useful information for those tasked with the improvement of scientific achievements.

Abstract
OBJECTIVE To estimate the rate and time to next live birth by mode of delivery. DESIGN Hospital-based cohort. SETTING Aarhus University Hospital (AUH), Denmark. POPULATION All pregnant women attending AUH were invited to enroll in the Aarhus Birth Cohort (ABC) study between 1989 and 2010 (n = 91,625). METHODS Women were followed from their first live birth until the subsequent live birth or until censoring due to study end using Cox regression models. MAIN OUTCOME MEASURES Rate and time to subsequent live birth according to mode of delivery. RESULTS 46,162 index live births were identified, of which 22,462 (49%) had a subsequent live birth. Women with any type of caesarean had a 6% reduction in the rate of subsequent live birth (HR 0.94, 95% CI 0.89, 0.98), which remained unchanged in the analysis by type (emergency, HR 0.95, 95% CI 0.89, 1.02; elective, HR 0.91, 95% CI 0.85, 0.98) compared with women who had a spontaneous vaginal delivery (SVD). Operative vaginal delivery was associated with an 8% reduction in subsequent live birth rates (HR 0.92, 95% CI 0.86, 0.98) and vaginal delivery complicated by shoulder dystocia with a 19% reduction compared with SVD. Median time to next birth in days was shortest in women with a first caesarean (994 days, 95% CI 973, 1026) and longest in women with a vaginal delivery complicated by shoulder dystocia (1065 days, 95% CI 994, 1191). In women with planned pregnancies, the shortest median time to second birth was in women with breech vaginal deliveries (859 days, 95% CI 737, 1089) and the longest in women with vaginal deliveries complicated by shoulder dystocia (1193 days, 95% CI 1028, 1430). CONCLUSION The impact of mode of delivery on subsequent rate and time to next birth was minimal in this study. The greatest reduction was among women with assisted vaginal delivery complicated by shoulder dystocia. This study is strengthened by data on pregnancy planning as well as information on complications of pregnancy, delivery and neonatal morbidities, all of which may influence a woman's decision on subsequent birth.

Abstract
STUDY QUESTION Does a primary Caesarean section influence the rate of, and time to, subsequent live birth compared with vaginal delivery? SUMMARY ANSWER Caesarean section was associated with a reduction in the rate of subsequent live birth, particularly among elective and maternal-requested Caesareans indicating maternal choice plays a role. WHAT IS KNOWN ALREADY Several studies have examined the relationship between Caesarean section and subsequent birth rate with conflicting results primarily due to poor epidemiological methods. STUDY DESIGN, SIZE, DURATION This Danish population register-based cohort study covered the period from 1982 to 2010 (N = 832 996). PARTICIPANTS/MATERIALS, SETTING, METHODS All women with index live births were followed until their subsequent live birth or censored (maternal death, emigration or study end) using Cox regression models. MAIN RESULTS AND THE ROLE OF CHANCE In all 577 830 (69%) women had a subsequent live birth. Women with any type of Caesarean had a reduced rate of subsequent live birth (hazard ratio [HR] 0.86, 95% confidence intervals [CI] 0.85, 0.87) compared with spontaneous vaginal delivery. This effect was consistent when analyses were stratified by type of Caesarean: emergency (HR 0.87, 95% CI 0.86, 0.88), elective (HR 0.83, 95% CI 0.82, 0.84) and maternal-requested (HR 0.61, 95% CI 0.57, 0.66) and in the extensive sub-analyses performed. LIMITATIONS, REASONS FOR CAUTION Lack of biological data to measure a woman's fertility is a major limitation of the current study. Unmeasured confounding and limited availability of data (maternal BMI, smoking, access to fertility services and maternal-requested Caesarean section) as well as changes in maternity care over time may also influence the findings. WIDER IMPLICATIONS OF THE FINDINGS This is the largest study to date and shows that Caesarean section is most likely not causally related to a reduction in fertility. Maternal choice to delay or avoid childbirth is the most plausible explanation. Our findings are generalizable to other middle- to high-income countries; however, cross country variations in Caesarean section rates and social or cultural differences are acknowledged.

Abstract
STUDY QUESTION When compared with vaginal delivery, is Cesarean delivery associated with reduced childbearing, a prolonged inter-birth interval or infertility? SUMMARY ANSWER Women whose first delivery was by Cesarean section were not significantly different from those who delivered vaginally with respect to subsequent deliveries, inter-birth interval or infertility after delivery. WHAT IS ALREADY KNOWN Some studies have suggested that delivery by Cesarean section reduces subsequent fertility, while others have reported no association. STUDY DESIGN, SIZE, DURATION This was a planned secondary analysis of the Mothers' Outcomes After Delivery study, a longitudinal cohort study. This analysis included 956 women with 1835 deliveries, who completed a study questionnaire at 6-11 years (median [interquartile range]: 8.1 [7.1, 9.8]) after their first delivery. PARTICIPANTS/MATERIALS, SETTING, METHODS Exclusion criteria regarding the first birth were: maternal age <15 or >50 years, delivery at <37 weeks gestation, placenta previa, multiple gestation, known fetal congenital abnormality, stillbirth, prior myomectomy and abruption. Of the 956 women included, the first delivery was by Cesarean section for 534 women and by vaginal birth for 422 women. Infertility was self-reported. To compare maternal characteristics by mode of first delivery, P-values were calculated using Fisher's exact test or Pearson's χ(2) test for categorical variables and a Kruskall-Wallis test for continuous variables. We also considered whether, across all deliveries to date, a prior Cesarean is associated with decreased fertility. In this analysis, self-reported infertility after each delivery (across all participants) was considered as a function of one or more prior Cesarean births, using generalized estimating equations to control for within-woman correlation. MAIN RESULTS AND THE ROLE OF CHANCE No differences were observed between the Cesarean and vaginal groups (for first delivery) with respect to infertility after their most recent delivery (7 versus 6%, P = 0.597), the interval between their first and second births (30.8 versus 30.6 months, P = 0.872), or multiparity (75 versus 76%, P = 0.650). Across all births, a history of Cesarean delivery was not significantly associated with infertility (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.64-1.26). Women who reported infertility prior to their first delivery were significantly more likely to report infertility after each subsequent delivery (OR, 5.16; 95% CI, 3.60-7.39). LIMITATIONS, REASONS FOR CAUTION Due to the use of self-reported infertility, the fertility status of some participants may be misclassified. Also, the small sample size may result in insufficient power to detect small differences between groups. Finally, a relatively high proportion of our participants were over age 35 at the time of first delivery (26%) and highly educated (37% with graduate degrees), which may indicate that our population may not be generalizable. WIDER IMPLICATIONS OF THE FINDINGS While some prior studies have shown decreased family size among women who deliver by Cesarean, our results suggest that the rate of infertility is not different after Cesarean compared with vaginal birth. Our findings should be reassuring to women who deliver by Cesarean section. STUDY FUNDING/COMPETING INTERESTS This study was funded by the US National Institutes of Health (NIH, R01-HD056275). No competing interests are declared. TRIAL REGISTRATION NUMBER N/A.

Abstract
In the last decades cesarean section rates increased in many countries becoming the most performed intraperitoneal surgical procedure. Despite its worldwide spread, a general consensus on the most appropriate technique to use has not yet been reached. The operative technique performed is made chiefly on the basis of the individual experience and preference of operators, the characteristics of patients, timing and urgency of intervention. We compared the two most known and used techniques, modified Misgav-Ladach and traditional Pfannenstiel-Kerr, and analyzed their impact on primary, short- and long-term outcomes and outcome related to health service use.
