Role of public and private funding in the rising caesarean section rate: a cohort study

Association of Maternal Risk Factors with the Prevalence of Caesarean Section Deliveries: A Cross-Sectional Study

In the last few years, there has been a gradually increasing rate of caesarean section deliveries worldwide that negatively affects both mothers' and children's health. The present survey intended to explore the relations of common maternal risk factors with the prevalence of caesarean sections. This is a cross-sectional study including 5182 healthy mothers from geographically diverse regions of Greece, which has applied relevant inclusion and exclusion criteria. An elevated 56.4% incidence of caesarean sections was noted. The prevalence of caesarean section deliveries was estimated to be 51.5% in private hospitals and 48.5% in public hospitals. Maternal age, pre-pregnancy overweight/obesity, excess gestational weight gain, preterm birth, financial status, smoking habits, and private type of birth hospital were considerably associated with a high probability of caesarean section, regardless of several confounders. In conclusion, caesarean section rates are constantly increasing, and various maternal risk factors additively elevate its incidence, which additionally enhances the likelihood of postpartum complications for both the mothers and their infants. Public health procedures and approaches are strongly recommended to notify future mothers of the potential risk factors that may result in adverse pregnancy outcomes of caesarean section delivery, highlighting its use only for emergency medical reasons and also promoting healthier nutritional and lifestyle habits that may reduce the increasing prevalence of caesarean section deliveries.

Caesarean Section Delivery Is Associated with Childhood Overweight and Obesity, Low Childbirth Weight and Postnatal Complications: A Cross-Sectional Study

Background and Objectives: In the last decades, simultaneously increasing trends have been recorded for both caesarean section delivery and childhood overweight/obesity around the world, which are considered serious public health concerns, negatively affecting child health. Aim: The present study aims to investigate whether caesarean section is associated with the increased rates of childhood overweight/obesity, low childbirth anthropometric indices and postnatal complications in pre-school age. Materials and Methods: This is a cross-sectional study in which 5215 pre-school children aged 2–5 years old were enrolled from nine different Greek regions after applying specific inclusion and exclusion criteria. Non-adjusted and adjusted statistical analysis was performed to assess the impact of caesarean section in comparison to vaginal delivery. Results: Children delivered by caesarean section were significantly more frequently overweight or obese at the age of 2–5 years, also presenting a higher prevalence of low birth weight, length and head circumference. Caesarean section was also associated with higher incidence of asthma and diabetes type I at the age of 2–5 years. In a multivariate analysis, caesarean section increased the risk of childhood overweight/obesity and low childbirth anthropometric indices even if adjusting for several childhood and maternal confounding factors. Conclusions: Increasing trends were recorded for both caesarean section delivery and childhood overweight/obesity, which are considered serious public health concerns. Caesarean section independently increased childhood overweight/obesity in pre-school age, highlighting the emergent need to promote health policies and strategies to inform future mothers about its short and long-term risks and that this mode of delivery should preferably be performed only when there are strong medical recommendations in emergency obstetric conditions.

Changes in caesarean section rates in China during the period of transition from the one-child to two-child policy era: cross-sectional National Household Health Services Surveys

OBJECTIVES

Since 2009, China has introduced policies, principally targeting health professionals, to reduce caesarean section (CS) overuse. In 2016, China endorsed a universal two-child policy. Advanced maternal age and previous CS may indicate changes in obstetric risks, which raise concerns on the need for and safety of CS. This study investigated changes in CS rates in 2008-2018, and factors associated with CS use during the period of transition from the one-child to two-child policy era.

DESIGN

We used births data from the cross-sectional National Household Health Services Surveys in 2013 and 2018.

SETTING

Population-based national survey.

PARTICIPANTS

Women who had the last live birth within 5 years before the survey.

PRIMARY OUTCOME MEASURE

CS rate.

RESULTS

Overall CS use increased from 40.9% in 2008 to 47.2% in 2014 with significant increase in rural areas and the western region, and slightly decreased to 45.2% in 2018 with the greatest decrease among nulliparous women. Maternal request for CS by urban nulliparous women decreased from 36.8% in 2008-2009 to 22.2% in 2016-2018, but this change was not statistically significant in rural areas. Maternal age over 35 years old (OR 2.40, 95% CI 1.72 to 3.35) and births that occurred at a private hospital (OR 1.52, 95% CI 1.25 to 1.86) were associated with CS use among nulliparous women in 2016-2018. The CS rate among multiparous women increased over time. Individual socioeconomic factors associated with CS use among multiparous women.

CONCLUSIONS

The CS rate rise in China in 2008-2018 is attributable to increased use in rural areas and the less developed western region. The population policy shift, alongside facility policies for unnecessary CS reduction, are likely factors in CS reduction in urban areas. The challenge remains to reduce unnecessary CS, at the same time as providing safe, universal access to CS for women in need.

Effects of the COVID-19 pandemic on perinatal outcomes: a retrospective cohort study from Turkey

Background

Lockdowns, pregnant women’s fear from hospitalization in addition to uncertainties about appropriate birthing practices at the beginning of the pandemic may have affected the health outcomes of mother-infant couples. We aimed to explore whether pregnancy outcomes including the rates of cesarean delivery (CS), preterm, and low birth weight (LBW) births have changed during the pandemic period compared with the pre-pandemic period.

Methods

We applied a population-based retrospective cohort, before-after approach in 2020 vs. similar calendar months in 2019 for five periods [Jan-Feb (pre-pandemic); March–May (1st wave and lockdown); June–August; September–October; November–December (2nd wave and lockdown)]. The data was modelled through multiple logistic regressions using key outcomes; CS, preterm, and LBW births as the dependent variables, and adjustments were made for independent variables in SPSS software. We evaluated the modification of years by periods by adding interaction term (yearXperiod) to the model.

Results

The rate of CS in hospital births increased from 57.7% in 2019 to 60.2% in 2020. CS rates were significantly increased during the 3rd and 4th periods. The overall preterm rate was 11%. When singleton pregnancies were considered, adjusted multivariable analyses showed a decrease in preterm proportions during all time periods with respect to the pre-pandemic period. The percentage of LBW was 7.7% during the pandemic period and was found to be significantly reduced compared to the pre-pandemic period. There was a significant reduction in LBW rates in all periods except the second lockdown period.

Conclusions

Our findings suggested significant reductions in preterm and LBW births possibly due to the indirect effects of the pandemic. Moreover, strategies need to be considered to address the increased CS rates and shifting of maternity service utilization to private facilities.

Can the Robson 10 Group Classification System help identify which groups of women are driving the high caesarean section rate in major private hospitals in eastern Ethiopia? A cross-sectional study

OBJECTIVE

The rates of caesarean section (CS) in Ethiopian private hospitals are high compared with those in public facilities, and there are limited descriptions of groups of women contributing to these high rates. The objective of this study was to describe the groups contributing to increased CS rates using the Robson classification in two major private hospitals in eastern Ethiopia.

DESIGN

Cross-sectional study.

SETTING

Two major private hospitals in eastern Ethiopia.

PARTICIPANTS

All women who gave birth from 9 January 2019 to 8 January 2020 in two major private hospitals in eastern Ethiopia.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was the Robson 10 Group Classification System. The secondary outcome was indication for CS as recorded in the medical files.

RESULTS

Of 1203 births in both hospitals combined during the study period, 415 (34.5%) were by CS. Women with a uterine scar due to previous CS (group 5), single cephalic term multiparous women in spontaneous labour (group 3) and single cephalic term nulliparous women in spontaneous labour (group 1) were the leading groups contributing 33%, 27.5% and 17.1%, respectively. The leading documented indications were fetal compromise (29.4%), previous CS (27.2%) and obstructed labour (12.3%).

CONCLUSION

More than three-fourths of CS were performed among Robson groups 5, 3 and 1, indicating inadequate trial of labour after CS or management of labour among relatively low-risk groups (3 and 1). Improving management of spontaneous labour and strengthening clinical practice around safely providing the option of vaginal birth after CS practice are strategies required to reduce the high CS rates in these private facilities.

Reproducing fear: the effect of birth stories on nulligravid women's birth preferences

OBJECTIVE

Preference for caesarean birth is associated with higher fear and lower self-efficacy for vaginal birth. Vicarious experience is a strong factor influencing self-efficacy in nulligravid women, and is increasingly accessible via digital and general media. This study assessed the effect of exposure to different birth stories on nulligravid women's childbirth preferences and the factors mediating these effects.

METHODS

Nulligravid women (N = 426) were randomly allocated to one of four conditions exposing them to written birth stories. Stories varied by type of birth (vaginal/caesarean) and storyteller evaluation (positive/negative) in a 2 × 2 design. Childbirth preference, fear of labour and vaginal birth, and self-efficacy for vaginal birth were measured before and after exposure via a two-way between groups analysis of covariance. Hierarchical regression models were used to determine the mediating effects of change in childbirth fear and childbirth self-efficacy.

RESULTS

Variations in type of birth and storyteller evaluation significantly influenced childbirth preferences (F (1, 421) = 44.78, p < 0.001). The effect of vaginal birth stories on preference was significantly mediated by fear of labour and vaginal birth and self-efficacy. Effects of exposure to caesarean birth stories were not explained by changes in fear or self-efficacy.

CONCLUSIONS

Childbirth preferences in nulligravid women can be significantly influenced by vicarious experiences. For stories about vaginal birth, the influence of birth stories on women's fear and self-efficacy expectancy are partly responsible for this influence. The findings highlight the importance of monitoring bias in vicarious experiences, and may inform novel strategies to promote healthy childbirth.

Do you pay to go private?: a single centre comparison of induction of labour and caesarean section rates in private versus public patients

Background

The aim of this study was to compare rates of induction and subsequent caesarean delivery among nulliparous women with private versus publicly funded health care at a single institution. This is a retrospective cohort study using the electronic booking and delivery records of nulliparous women with singleton pregnancies who delivered between 2010 and 2015 in an Irish Tertiary Maternity Hospital (approx. 9000 deliveries per annum).

Methods

Data were extracted from the National Maternity Hospital (NMH), Dublin, Patient Administration System (PAS) on all nulliparous women who delivered a liveborn infant at ≥37 weeks gestation during the 6-year period. At NMH, all women in spontaneous labour are managed according to a standardised intrapartum protocol. Twenty-two thousand two hundred thirty-two women met the inclusion criteria. Of these, 2520 (12.8%) were private patients; the remainder (19,712; 87.2%) were public. Mode of and gestational age at delivery, rates of and indications for induction of labour, rates of pre-labour caesarean section, and maternal and neonatal outcomes were examined. Rates of labour intervention and subsequent maternal and neonatal outcomes were compared between those with and without private health cover.

Results

Women attending privately were more than twice as likely to have a pre-labour caesarean section (12.7% vs. 6.5%, RR = 2.0, [CI 1.8–2.2])); this finding persisted following adjustment for differences in maternal age and body mass index (BMI) (adjusted relative risk 1.74, [CI 1.5–2.0]). Women with private cover were also more likely to have induction of labour and significantly less likely to labour spontaneously. Women who attended privately were significantly more likely to have an operative vaginal delivery, whether labour commenced spontaneously or was induced.

Conclusions

These findings demonstrate significant differences in rates of obstetric intervention between those with private and public health cover. This division is unlikely to be explained by differences in clinical risk factors as no significant difference in outcomes following spontaneous onset of labour were noted. Further research is required to determine the roots of the disparity between private and public decision-making. This should focus on the relative contributions of both mothers and maternity care professionals in clinical decision making, and the potential implications of these choices.

A survey of obstetricians' attitudes to induction of labour at 39 weeks gestation with the intention of reducing caesarean section rates

BACKGROUND

Induction of labour (IOL) and caesarean section (CS) rates continue to increase in Australia, New Zealand and globally. There is evidence that CS rates are decreased in the context of medically indicated and elective IOL; therefore, the emerging concept of using IOL as means of preventing CS warrants investigation.

AIMS

To assess obstetricians' opinions of elective IOL at 39 weeks gestation, its feasibility, generalisability and utility as a means of preventing CS in Australia and New Zealand.

MATERIALS AND METHODS

A de-identified cross-sectional survey was distributed electronically to all Fellows and trainees of The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG). The survey was voluntary and distributed with the approval of the RANZCOG Continuing Education Committee. The survey addressed opinions relating to rates of and indications for IOL, the perceived validity of those indications and explored the acceptability of using a screening tool to predict women at increased risk of intra-partum CS and tailoring obstetric management to include the option of IOL at 39 weeks gestation.

RESULTS

The overall response rate was 34% (492/1423) (including trainees) and the response rate was 53% (394/750) for currently practising obstetricians. The majority (90%) of responders agreed on medical and clinical indications for IOL. There was no consensus on the validity of IOL if a woman were at apparent high risk of intra-partum CS; however, 81% (360/443) of clinicians would be interested in a tool that could predict those women at risk.

CONCLUSIONS

There is heterogeneity of obstetrician's beliefs on using IOL at 39 weeks as a mechanism to reduce the CS rate.

Birth preparation acupuncture for normalising birth: An analysis of NHS service routine data and proof of concept

A number of studies show that acupuncture may help with labour and delivery. An NHS maternity acupuncture service providing birth preparation acupuncture has assessed its routine hospital maternity annual data from 2014 to 2016 to see what effect it had on labour and delivery outcomes. The data from this service was analysed and women who had birth preparation acupuncture were compared with those who did not receive it. Maternal age, parity and socio-economic status were considered confounders and were adjusted for in the analysis. Women who received acupuncture had more normal births (less surgical births) [OR 0.76 (0.64, 0.91)], required less intrapartum analgesia [OR 0.74 (0.63, 0.86)], fewer components of an induction of labour [OR 0.74 (0.61, 0.91)] and a reduced length of a hospital stay [OR 0.91 (0.87, 0.95)]. The patients highly valued the availability of acupuncture within the maternity service as it enhanced their patient journey.Impact statementWhat is already known on this subject? Numerous studies provide evidence for the effects of acupuncture in normalising pregnancy and birth. These effects include musculoskeletal preparation of the pelvis, cervical ripening, enhancing endogenous oxytocin release, and analgesic properties.What do the results of this study add? Our analysis shows that women who received birth preparation acupuncture had fewer surgical births, required less intrapartum analgesia, less components of induction of labour and had a reduced length of hospital stay, supporting the use of maternity acupuncture in normalising birth outcomes.What are the implications of these findings for clinical practice and/or further research? The findings show that acupuncture, by potentially normalising birth, may lead to reductions in costs of service. Further, additional research is required to see whether acupuncture is cost effective and could have an adjunctive role as a complementary therapy for improving birth outcomes and a woman's experience of childbirth.

Prevalence and Associated Factors of Caesarean Section and its Impact on Early Initiation of Breastfeeding in Abu Dhabi, United Arab Emirates

The World Health Organization (WHO) recommends the early initiation of breastfeeding. Research shows that factors such as mode of delivery may interfere with the early initiation of breastfeeding. However, data in the United Arab Emirates (UAE) on these findings is limited. Thus, the aim of this study was to describe the prevalence of caesarean sections (CSs) and evaluate their effect on breastfeeding initiation among mothers of children under the age of two years in Abu Dhabi. Data were collected in clinical and non-clinical settings across various geographical areas in Abu Dhabi during 2017 using consent and structured questionnaires for interviews with mothers. Data analysis included both descriptive and inferential statistics. Among the 1624 participants, one-third (30.2%) reportedly delivered by CS, of which 71.1% were planned, while 28.9% were emergency CS. More than half of all mothers (62.5%) initiated early breastfeeding. Multivariable logistic regression indicated factors that were associated positively with CS included advanced maternal age, nationality, and obesity. However, gestational age (GA) was negatively associated with CS. This study shows that the prevalence of CS is high in Abu Dhabi, UAE. CS is associated with lower early initiation rates of breastfeeding. The early initiation rates of breastfeeding were 804 (79.2%) 95% confidence interval (CI) (76.4, 82.0), 162 (16.0%) 95% CI (10.4, 21.6), and 49 (4.8%) 95% CI (1.2, 10.8) among vaginal delivery, planned CS, and emergency CS, respectively. Regarding the mode of delivery, vaginal were 2.78 (Adjusted Odd Ratio (AOR)): CI (95%), (2.17–3.56, p < 0.001) times more likely related to an early initiation of breastfeeding. CS in general, and emergency CS, was the main risk factor for the delayed initiation of breastfeeding. The study provides valuable information to develop appropriate strategies to reduce the CS rate in UAE. Maternal literacy on CS choices, the importance of breastfeeding for child health, and additional guidance for mothers and their families are necessary to achieve better breastfeeding outcomes.

Caesarean sections in the in the context of the Chiranjeevi Yojana public private partnership program to promote institutional birth in Gujarat, India; does the embedded disincentive for caesarean section work?

Background

The government of Gujarat, India runs a large public private partnership program to widen access to emergency obstetric care (EmOC). The program include a disincentive for Cesareans section (CS) which are capped at seven per 100 women. In this paper, we study if the disincentive works by comparing CS rates among similar groups of women who deliver within and outside the program.

Methods

Community-based panel study in three districts of Gujarat, India. Sample size: 2123 women. Data was analyzed using multivariable logistic regression.

Results

Overall seven point seven % (164/2123) of the all women in the study had a CS. After adjusting for confounding factors women within the program had 62% (AOR 0.38, 95% CI 0.22–0.44) lower odds of having a CS than to non-beneficiaries. In a separate model of predictors of CS among women giving birth only in program accredited hospitals, we found that CY program beneficiaries had lower odds of having a CS birth than non-beneficiary women (paying clients) (AOR 0.40, 95% CI 0.24–0.67).

Conclusions

The Gujarat government is trying to ensure access to EmOC (including CS) for its vulnerable population through CY. The embedded disincentive to prevent unnecessary cesareans by private obstetricians is a novel one, and appears to work, though one could argue it works ‘over-efficiently’ by depriving some women who need CS from receiving one under the program. The state needs to revisit and review what is happening in the program periodically, and have oversight over whether women who need CS under the program actually receive the care that they need.

Trends and predictors of cesarean birth in Singapore, 2005-2014: A population-based cohort study

BACKGROUND

Rates of cesarean birth have continued to rise in many high-income countries. We examined the temporal trends and predictors of cesarean birth in Singapore.

METHODS

Linked hospitalization and Birth Registry data were used to examine all live births to Singaporean citizens and permanent residents between January 1, 2005 and December 31, 2014 (n = 342 932 births). We calculated cesarean rates and age-adjusted average annual percent change (AAPC) in those rates and used sequential multivariable regression modeling to assess the contribution of changes in predictors to the change in cesarean rates over time.

RESULTS

The overall cesarean rate in Singapore rose from 32.2% in 2005 to 37.4% in 2014. Among singleton, cephalic, term pregnancies, the two major predictions of cesarean were nulliparity and previous cesarean, each accounting for just over one-third of all cesareans. Higher AAPC was observed in nulliparous women of Indian ethnicity (0.74% [95% confidence interval 0.68-0.80]) compared with Chinese (0.62% [0.60-0.65]) or Malay women (0.63% [0.59-0.68]), and in women who delivered in private hospitals (0.62% [0.60-0.64]) compared with those delivered under subsidized care in public hospitals (0.58% [0.52-0.63]). Parity and education had the largest influences on cesarean birth trend (attenuation of AAPC from 0.62% [0.59-0.66] to 0.39% [0.38-0.40] after adjustment).

CONCLUSION

Cesarean birth has continued to rise at a steady rate in Singapore. Strategies to curb this temporal increase include avoidance of medically unnecessary primary cesarean and attempts at trial of labor and vaginal delivery among women with a history of prior cesarean.

Global epidemiology of use of and disparities in caesarean sections

In this Series paper, we describe the frequency of, trends in, determinants of, and inequalities in caesarean section (CS) use, globally, regionally, and in selected countries. On the basis of data from 169 countries that include 98·4% of the world's births, we estimate that 29·7 million (21·1%, 95% uncertainty interval 19·9-22·4) births occurred through CS in 2015, which was almost double the number of births by this method in 2000 (16·0 million [12·1%, 10·9-13·3] births). CS use in 2015 was up to ten times more frequent in the Latin America and Caribbean region, where it was used in 44·3% (41·3-47·4) of births, than in the west and central Africa region, where it was used in 4·1% (3·6-4·6) of births. The global and regional increases in CS use were driven both by an increasing proportion of births occurring in health facilities (accounting for 66·5% of the global increase) and increases in CS use within health facilities (33·5%), with considerable variation between regions. Based on the most recent data available for each country, 15% of births in 106 (63%) of 169 countries were by CS, whereas 47 (28%) countries showed CS use in less than 10% of births. National CS use varied from 0·6% in South Sudan to 58·1% in the Dominican Republic. Within-country disparities in CS use were also very large: CS use was almost five times more frequent in births in the richest versus the poorest quintiles in low-income and middle-income countries; markedly high CS use was observed among low obstetric risk births, especially among more educated women in, for example, Brazil and China; and CS use was 1·6 times more frequent in private facilities than in public facilities.

Caesarean section and risk of autism across gestational age: a multi-national cohort study of 5 million births

Background

The positive association between caesarean section (CS) and autism spectrum disorder (ASD) may be attributed to preterm delivery. However, due to lack of statistical power, no previous study thoroughly examined this association across gestational age. Moreover, most studies did not differentiate between emergency and planned CS.

Methods

Using population-based registries of four Nordic countries and Western Australia, our study population included 4 987 390 singletons surviving their first year of life, which included 671 646 CS deliveries and 31 073 ASD children. We used logistic regression to estimate odds ratios (OR) and their 95% confidence intervals (CI) for CS, adjusted for gestational age, site, maternal age and birth year. Stratified analyses were conducted by both gestational age subgroups and by week of gestation. We compared emergency versus planned CS to investigate their potential difference in the risk of ASD.

Results

Compared with vaginal delivery, the overall adjusted OR for ASD in CS delivery was 1.26 (95% CI 1.22-1.30). Stratified ORs were 1.25 (1.15-1.37), 1.16 (1.09-1.23), 1.34 (1.28-1.40) and 1.17 (1.04-1.30) for subgroups of gestational weeks 26-36, 37-38, 39-41 and 42-44, respectively. CS was significantly associated with risk of ASD for each week of gestation, from week 36 to 42, consistently across study sites (OR ranged 1.16-1.38). There was no statistically significant difference between emergency and planned CS in the risk of ASD.

Conclusion

Across the five countries, emergency or planned CS is consistently associated with a modest increased risk of ASD from gestational weeks 36 to 42 when compared with vaginal delivery.

Comparison between public and private sectors of care and disparities in adverse neonatal outcomes following emergency intrapartum cesarean at term - A retrospective cohort study

BACKGROUND

Perinatal outcomes may be influenced by a variety of factors including maternal demographics and medical condition as well as socio-economic status. The evidence for disparities in health outcomes stratified by type of care (public or private) is lacking. The aim of this study was to investigate short term neonatal outcomes following category 1 and 2 emergency cesareans at term between publicly and privately funded women at a single major tertiary centre in Australia. Category 1-immediate threat to life (maternal or fetal); Category 2-maternal or fetal compromise that is not immediately life-threatening.

METHODS

This was a retrospective, cross sectional study of 61355 term singleton babies born at the Mater Mother's Hospital in Brisbane, Australia in 2007-2014. We collected data from the hospital's maternity database and compared maternal demographics, indications for cesarean and neonatal outcomes for publicly and privately funded women.

RESULTS

Over the study period there were 32477 public and 28878 private, term singleton births. Compared to the publicly funded cohort, privately insured women were older, had lower BMI, were of Caucasian ethnicity, Australian born, nulliparous, had shorter labors and had lower rates of hypertensive disorders and diabetes. The most common indications for category 1 and category 2 cesareans in combination were non-reassuring fetal status followed by failure to progress in labor and malpresentation. For both category 1 and 2 cesareans, neonatal outcomes (Apgar score <7 at 5 minutes, abnormal cord gases, Neonatal Critical Care Unit admission rates, rates of severe respiratory distress and jaundice) were significantly worse in the publicly funded compared to the privately insured cohort Multivariate analyses controlling for maternal age, ethnicity, country of birth, parity, hypertension, diabetes mellitus, gestational age at birth and length of labour confirmed that private insurance status was highly protective for the perinatal outcomes of Apgar score <7 at 5 minutes (aOR 0.26, 95% CI 0.13-0.55), admission to NCCU (OR 0.51, 95% CI 0.30-0.92) and respiratory distress (aOR 0.60, 95% CI 0.41-0.86).

CONCLUSION

Birth in the private health sector was inversely associated with adverse neonatal outcomes following category 1 and 2 cesareans.

Preference for cesarean section in young nulligravid women in eight OECD countries and implications for reproductive health education

Background

Efforts to reduce unnecessary Cesarean sections (CS) in high and middle income countries have focused on changing hospital cultures and policies, care provider attitudes and behaviors, and increasing women’s knowledge about the benefits of vaginal birth. These strategies have been largely ineffective. Despite evidence that women have well-developed preferences for mode of delivery prior to conceiving their first child, few studies and no interventions have targeted the next generation of maternity care consumers. The objectives of the study were to identify how many women prefer Cesarean section in a hypothetical healthy pregnancy, why they prefer CS and whether women report knowledge gaps about pregnancy and childbirth that can inform educational interventions.

Methods

Data was collected via an online survey at colleges and universities in 8 OECD countries (Australia, Canada, Chile, England, Germany, Iceland, New Zealand, United States) in 2014/2015. Childless young men and women between 18 and 40 years of age who planned to have at least one child in the future were eligible to participate. The current analysis is focused on the attitudes of women (n = 3616); rates of CS preference across countries are compared, using a standardized cohort of women aged 18–25 years, who were born in the survey country and did not study health sciences (n = 1390).

Results

One in ten young women in our study preferred CS, ranging from 7.6% in Iceland to 18.4% in Australia. Fear of uncontrollable labor pain and fear of physical damage were primary reasons for preferring a CS. Both fear of childbirth and preferences for CS declined as the level of confidence in women’s knowledge of pregnancy and birth increased.

Conclusion

Education sessions delivered online, through social media, and face-to-face using drama and stories told by peers (young women who have recently had babies) or celebrities could be designed to maximize young women’s capacity to understand the physiology of labor and birth, and the range of methods available to support them in coping with labor pain and to minimize invasive procedures, therefore reducing fear of pain, bodily damage, and loss of control. The most efficacious designs and content for such education for young women and girls remains to be tested in future studies.

Possible relationship between general and pregnancy-related anxiety during the first half of pregnancy and the birth process: a prospective cohort study

OBJECTIVES

The rate of interventions during childbirth has increased dramatically during the last decades. Maternal anxiety might play a role in the progress of the labour process and interventions during labour. This study aimed to identify associations between anxiety in the first half of pregnancy and the birth process, including any interventions required during labour. In addition, differences in the associations by parity and ethnicity were explored.

DESIGN

Prospective cohort study.

SETTING

Primary care midwifery practices and secondary/tertiary care obstetric practices in Amsterdam, participating in the multiethnic ABCD (Amsterdam Born Children and their Development) study (participation rate 96%; response 8266/12 373 (67%)).

PARTICIPANTS

Included were women with singletons, alive at labour start, with a gestational age ≥24 weeks (n=6443).

INDEPENDENT VARIABLE

General anxiety (State-Trait Anxiety Inventory state) and pregnancy-related anxiety (Pregnancy-Related Anxieties Questionnaire (PRAQ)) were self-reported in the first half of pregnancy.

OUTCOMES

Associations between both forms of anxiety and several indicators of the birth process were analysed. Subgroup analyses were performed for parity and ethnicity.

RESULTS

The prevalence of high general anxiety (State-Trait Anxiety Inventory score ≥43) and pregnancy-related anxiety (PRAQ score ≥P90) were 30.9% and 11.0%, respectively. After adjustment, in nulliparae, both general anxiety and pregnancy-related anxiety were associated with pain relief and/or sedation (OR for general anxiety 1.23; 95% CI 1.02 to 1.48; OR for pregnancy-related anxiety 1.45; 95% CI 1.14 to 1.85). In multiparae, general anxiety was associated with induction of labour (OR 1.53; 95% CI 1.16 to 2.03) and pregnancy-related anxiety was associated with primary caesarean section (OR 1.66; 95% CI 1.02 to 2.70). Associations were largely similar for all ethnicities.

CONCLUSIONS

High levels of general and pregnancy-related anxiety in early pregnancy contribute modestly to more interventions during the birth process with similar associations between ethnic groups, but with some differences between nulliparae and multiparae.

Beyond too little, too late and too much, too soon: a pathway towards evidence-based, respectful maternity care worldwide

On the continuum of maternal health care, two extreme situations exist: too little, too late (TLTL) and too much, too soon (TMTS). TLTL describes care with inadequate resources, below evidence-based standards, or care withheld or unavailable until too late to help. TLTL is an underlying problem associated with high maternal mortality and morbidity. TMTS describes the routine over-medicalisation of normal pregnancy and birth. TMTS includes unnecessary use of non-evidence-based interventions, as well as use of interventions that can be life saving when used appropriately, but harmful when applied routinely or overused. As facility births increase, so does the recognition that TMTS causes harm and increases health costs, and often concentrates disrespect and abuse. Although TMTS is typically ascribed to high-income countries and TLTL to low-income and middle-income ones, social and health inequities mean these extremes coexist in many countries. A global approach to quality and equitable maternal health, supporting the implementation of respectful, evidence-based care for all, is urgently needed. We present a systematic review of evidence-based clinical practice guidelines for routine antenatal, intrapartum, and postnatal care, categorising them as recommended, recommended only for clinical indications, and not recommended. We also present prevalence data from middle-income countries for specific clinical practices, which demonstrate TLTL and increasing TMTS. Health-care providers and health systems need to ensure that all women receive high-quality, evidence-based, equitable and respectful care. The right amount of care needs to be offered at the right time, and delivered in a manner that respects, protects, and promotes human rights.

Differences in nulliparous caesarean section rates across models of care: a decomposition analysis

BACKGROUND

To evaluate the extent of the difference in elective (ELCS) and emergency (EMCS) caesarean section (CS) rates between nulliparous women in public maternity hospitals in Ireland by model of care, and to quantify the contribution of maternal, clinical, and hospital characteristics in explaining the difference in the rates.

METHODS

Cross-sectional analysis using a combination of two routinely collected administrative databases was performed. A non-linear extension of the Oaxaca-Blinder method is used to decompose the difference between public and private ELCS and EMCS rates into the proportion explained by the differences in observable maternal, clinical, and hospital characteristics and the proportion that remains unexplained.

RESULTS

Of the 29,870 babies delivered to nulliparous women, 7,792 were delivered via CS (26.1 %), 79.6 % of which were coded as EMCS. Higher prevalence of ELCS was associated with breech presentation, other malpresentation, and the mother being over 40 years old. Higher prevalence of EMCS was associated with placenta praevia or placental abruption, diabetes (pre-existing and gestational), and being over 40 years old. The private model of care is associated with ELCS and EMCS rates 6 percentage points higher compared than the public model of care but this differential is insignificant in the fully adjusted models for EMCS. Just over half (53 %) of the 6 percentage point difference in ELCS rates between the two models of care can be accounted for by maternal, clinical and hospital characteristics. Almost 80 % of the difference for EMCS can be accounted for.

CONCLUSIONS

The majority of the difference in EMCS rates across models of care can be explained by differing characteristics between the two groups of women. The main contributor to the difference was advancing maternal age. The unexplained component of the difference for ELCS is larger; an excess private effect remains after accounting for maternal, clinical, and hospital characteristics. This requires further investigation and may be mitigated in future with the introduction of clinical guidelines related to CS.

Association between childbirth attitudes and fear on birth preferences of a future generation of Australian parents

BACKGROUND

The reality of childbirth fear is recognised for expectant parents but we lack knowledge about the childbirth attitudes of the next generation of Australian parents.

AIM

Examination of adults' attitudes toward childbirth including influencing contributing factors, fear scores, birth preferences and reasons for this preference.

METHODS

A cross-sectional online study was conducted with 654 Western Australian students attending one tertiary institution. Students (male and female) were eligible to participate if they were less than 40 years of age and did not currently have children but confirmed their intention to become parents. To assess associations or comparison of means, bi-variable analyses (Chi square test, Fisher's Exact test, Independent Student's t-test or one way ANOVA) were used. Factors associated with childbirth fear and birth preferences were assessed with binary logistic regression analysis.

FINDINGS

Childbirth attitudes were shaped by family members' (82.0%) and friends' experiences (64.4%) plus media (TV, YouTube, and movies) (63.5%). Furthermore, 15.6% of adults indicated a preference for a caesarean birth, even without obstetric complications. Likewise, 26.1% reported elevated fear; students with elevated fear scores had 2.6 times greater odds of wanting a caesarean birth. Only 23.4% of students felt confident about their childbirth knowledge.

CONCLUSION

Adults reported fear levels that warrant attention prior to a future pregnancy. Although the majority would choose a vaginal birth, they require awareness of benefits and risks for both vaginal and caesarean births to ensure their decisions reflect informed choice rather than influences of inadequate knowledge or fear.

Factors contributing to the rapid rise of caesarean section: a prospective study of primiparous Chinese women in Shanghai

OBJECTIVE

To identify factors contributing to the rapid rise of caesarean section in Shanghai through the prospective observation of changes in the preferred mode of delivery in pregnancy among primiparous Chinese women.

DESIGN

Prospective study.

SETTING

Two general hospitals in Shanghai.

PARTICIPANTS

A cohort of 832 low-risk primiparous women participated in the investigation from 2010-2012 three consecutive times, from their second to third trimester and, finally, 1-2 days post partum.

METHODS

Participants were interviewed, using standard questionnaires, for information on demographic characteristics, maternal childbirth self-efficacy, their preference of delivery mode before childbirth and on the people most influential to them when making decisions on delivery mode. Caesarean section indications in the medical records were extracted by the investigators and assessed against clinical guidelines. Caesarean sections were categorised into three groups: guideline-defined indications, doctor-defined indications and maternal request.

MAIN OUTCOME MEASURES

Preferred mode of delivery; indications for caesarean section; actual mode of delivery; determinants of caesarean section.

RESULTS

Of 832 pregnant women enrolled, 13.2% preferred caesarean section in the second trimester. This figure rose to 17.0% in the third trimester among 599 followed women. Of 523 women completing all three interviews, 58.1% underwent caesarean section. However, 34.9% of women undergoing caesarean section did not have any indications listed in the clinical guidelines nor based on maternal request. Multinomial regression analysis showed that doctors' influence was one of the significant risk factors of undergoing caesarean section, with doctor-defined indications. Participants with low maternal childbirth self-efficacy were more likely to request caesarean sections themselves.

CONCLUSIONS

When deciding to deliver via caesarean section without justified clinical indications in the guideline, Chinese doctors played an important role in decision-making. Among primiparous Chinese women, decisions to use caesarean sections were often made during the third trimester or during the process of labour.

Patterns of social inequalities across pregnancy and birth outcomes: a comparison of individual and neighborhood socioeconomic measures

BACKGROUND

This paper identifies patterns of health inequalities (consistency and magnitude) of socioeconomic disparities for multiple maternal and child health (MCH) outcomes that represent different health care needs of mothers and infants.

METHODS

Using cross-sectional national data (unweighted sample = 6,421, weighted =76,508) from the Canadian Maternity Experiences Survey linked with 2006 Canadian census data, we categorized 25 health indicators of mothers of singletons into five groups of MCH outcomes (A. maternal and infant health status indicators; B. prenatal care; C. maternal experience of labor and delivery; D. neonatal medical care; and E. postpartum infant care and maternal perceptions of health care services). We then examined the association of these health indicators with individual socioeconomic position (SEP) (education and income), neighborhood SEP and combined SEP (a four-level measure of low and high individual and neighborhood SEP), and compared the magnitude (odds ratios and 95% confidence intervals) and direction of the associations within and between MCH outcome groups.

RESULTS

We observed consistent positive gradients of socioeconomic inequalities within most groups and for 23/25 MCH outcomes. However, more significant associations and stronger gradients were observed for the MCH outcomes in the maternal and infant health status group as opposed to other groups. The neonatal medical care outcomes were weakly associated with SEP. The direction of associations was negative between some SEP measures and HIV testing, timing of the first ultrasound, caesarean section, epidural for vaginal births, infant needing non-routine neonatal care after discharge and any breastfeeding at 3 or 6 months. Gradients were steep for individual SEP but moderate for neighborhood SEP. Combined SEP had no consistent gradients but the subcategory of low individual-high neighborhood SEP often showed the poorest health outcomes compared to the categories within this SEP grouping.

CONCLUSION

By examining SEP gradients in multiple MCH outcomes categorized into groups of health care needs, we identified large and consistent inequalities both within and between these groups. Our results suggest differences in pathways and mechanisms contributing to SEP inequalities across groups of MCH outcomes that can be examined in future research and inform prioritization of policies for reducing these inequalities.

Googling caesarean section: a survey on the quality of the information available on the Internet

OBJECTIVE

To examine the quality and completeness of information on caesarean section in web pages used by laypersons in Brazil, a country with very high rates of caesarean delivery.

DESIGN

Cross-sectional study.

SETTING

Brazil.

SAMPLE

A total of 176 Internet websites.

METHODS

The term 'caesarean delivery' and 25 synonyms were entered into the most popular search engines in Brazil. The first three pages of hits were downloaded and assessed by two independent investigators using the DISCERN instrument and a content checklist.

MAIN OUTCOME MEASURES

Quality and completeness of information on caesarean section.

RESULTS

A total of 3900 web pages were retrieved and 176 fulfilled the selection criteria. The overall average DISCERN score was 43.6 (±8.9 SD), of a maximum score of 75; 30% of the pages were of poor or very poor quality and 47% were of moderate quality. Most pages scored low, especially in questions related to reliability of the information. The most frequently covered topics were: indications for caesarean section (80% of websites), which did not reflect clinical practice; short-term maternal risks (80%); and potential benefits of caesarean section (56%), including maternal and doctor convenience. Less than half of the websites mentioned perinatal risks and less than one-third mentioned long-term maternal risks associated with caesarean section, such as uterine rupture (17%) or placenta praevia/accreta (12%) in future pregnancies.

CONCLUSIONS

The quality and completeness of web-based resources in Portuguese about caesarean section were poor to moderate. Pending improvement of these resources, obstetricians should warn pregnant women about these facts and encourage them to discuss what they have read on the Internet about caesarean section.

TWEETABLE ABSTRACT

The quality and completeness of information about caesareans is poor in 176 websites used by Brazilians.

Influence of delivery characteristics and socioeconomic status on giving birth by caesarean section - a cross sectional study during 2000-2010 in Finland

Background

Caesarean section (CS) rates especially without medical indication are rising worldwide. Most of indications for CS are relative and CS rates for various indications vary widely. There is an increasing tendency to perform CSs without medical indication on maternal request. Women with higher socioeconomic status (SES) are more likely to give birth by CS. We aimed to study whether giving birth by CS was associated with SES and other characteristics among singleton births during 2000–2010 in Finland with publicly funded health care.

Methods

Data were gathered from the Finnish Medical Birth Register. The likelihood of giving birth by CS according to CS type (planned and non-planned), parity (nulliparous vs. multiparous), socio-demographic factors, delivery characteristics and time periods (2000–2003, 2004–2007 and 2008–2010) was determined by using logistic regression analysis. SES was classified as upper white collar workers (highest SES), lower white collar workers, blue collar workers (lowest SES), others (all unclassifiable cases) and cases with missing information.

Results

In total, 19.8% (51,511 of 259,736) of the nulliparous women and 13.1% (47,271 of 360,727) of the multiparous women gave birth by CS. CS was associated with several delivery characteristics, such as placental abruption, placenta previa, birth weight and fear of childbirth, among both parity groups. After adjustment, the likelihood of giving birth by planned CS was reduced by 40% in nulliparous and 55% in multiparous women from 2000–2003 to 2008–2010, whereas the likelihood of non-planned CSs did not change. Giving birth by planned and non-planned CS was up to 9% higher in nulliparous women and up to 17% higher in multiparous women in the lowest SES groups compared to the highest SES group.

Conclusions

Giving birth by CS varied by clinical indications. Women with the lowest SES were more likely to give birth by CS, indicating that the known social disparity in pregnancy complications increases the need for operative deliveries in these women. Overall, the CS policy in Finland shows favoring a trial of labor over planned CS and reflects no inequity in healthcare services.
