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

Women's caesarean section preferences: A multicountry cross-sectional survey in low- and middle-income countries

OBJECTIVE

To measure the proportion of women's preferences for CS in hospitals with high caesarean section rates and to identify related factors.

DESIGN

A cross-sectional hospital-based postpartum survey was conducted. We used multilevel multivariate logistic regression and probit models to analyse the association between women's caesarean section preferences and maternal characteristics. Probit models take into account selection bias while excluding women who had no preference.

SETTING

Thirty-two hospitals in Argentina, Thailand, Vietnam and Burkina Faso were selected.

PARTICIPANTS

A total of 1,979 post-partum women with no potential medical need for caesarean section were included among a representative sample of women who delivered at each of the participating facilities during the data collection period.

FINDINGS

The overall caesarean section rate was 23.3 %. Among women who declared a preference in late pregnancy, 9 % preferred caesarean section, ranging from 1.8 % in Burkina Faso to 17.8 % in Thailand. Primiparous women were more likely to prefer a caesarean section than multiparous women (β=+0.16 [+0.01; +0.31]; p = 0.04). Among women who preferred caesarean section, doctors were frequently cited as the main influencers, and "avoid pain in labour" was the most common perceived benefit of caesarean section.

KEY CONCLUSIONS

Our results suggest that a high proportion of women prefer vaginal birth and highlight that the preference for caesarean section is linked to women's fear of pain and the influence of doctors. These results can inform the development of interventions aimed at supporting women and their preferences, providing them with evidence-based information and changing doctors' behaviour in order to reduce the number of unnecessary caesarean sections.

Labor Neuraxial Analgesia and Its Association With Perinatal Outcomes in China in 2015-2016: A Propensity Score-Matched Analysis

BACKGROUND

The use of labor neuraxial analgesia (NA) in China has increased significantly in the past decade, and the current rate of use is unknown. This study aimed to describe the epidemiology of NA based on a large multicenter cross-sectional survey, the China Labor and Delivery Survey (CLDS) (2015-2016), and to evaluate the association between NA and intrapartum caesarean delivery (CD) and maternal and neonatal outcomes.

METHODS

The CLDS was a facility-based cross-sectional investigation with a cluster random sampling scheme conducted from 2015 to 2016. A specific weight was assigned to each individual based on the sampling frame. Logistic regression was adopted to analyze the factors associated with the use of NA. A propensity score matching scheme was used to analyze the associations between NA and intrapartum CD and perinatal outcomes.

RESULTS

A total of 51,488 vaginal deliveries or intrapartum CD were included in our study, excluding prelabor CDs. The weighted NA rate was 17.3% (95% confidence interval [CI], 16.6-18.0) in this survey population. Nulliparous, previous CD, hypertensive disorders, and labor augmentation were associated with higher use of NA. In the propensity score-matched analysis, NA was associated with reduced risks of intrapartum CD, especially intrapartum CD by maternal request (adjusted odds ratio [aOR], 0.68; 95% CI, 0.60-0.78 and aOR, 0.48; 95% CI, 0.30-0.76, respectively), 3rd or 4th degree perineal laceration (aOR, 0.36; 95% CI, 0.15-0.89), and 5-minute Apgar score ≤3 (aOR, 0.15; 95% CI, 0.03-0.66).

CONCLUSIONS

The use of NA may be associated with improved obstetric outcomes, including fewer intrapartum CD, less birth canal trauma, and better neonatal outcomes in China.

Risk factors of caesarean deliveries in urban-rural areas of Bangladesh

Background and aims

The key interest of this research is to identify the causes of the ongoing increasing trends in caesarean section or C-section (CS) deliveries in both urban and rural areas of Bangladesh.

Methods

This study analyzed all Bangladesh Demographic and Health Survey (BDHS) datasets through Chi-square and z tests and the multivariable logistic regression model.

Results

CS deliveries were found to be more prevalent in urban than in rural areas of Bangladesh. Mothers above 19 years, above 16 years at first birth, overweight mothers, those with higher educational levels, those who received more than one antenatal care (ANC) visit, fathers having secondary/higher education degrees and employed as workers or in business, and mothers living in wealthy households in the cities of Dhaka, Khulna, Mymensingh, Rajshahi, and Rangpur divisions had a significantly higher likelihood of CS deliveries in urban areas. Contrastingly, mothers with ages between 20 and 39 years, above 20 years at first birth, normal weight/overweight mothers, those with primary to higher level of education, those in the business profession, fathers who also received primary to higher education, mothers who received more than one ANC visit, and those living in wealthy households in Dhaka, Khulna, Mymensingh, Rajshahi, and Rangpur divisions were more likely to have CS deliveries in rural areas. The 45-49 age group mothers had a five times higher likelihood of CS deliveries [odds ratio (OR): 5.39] in urban areas than in rural areas. Wealthy mothers were more likely to be CS-delivered in urban (OR: 4.84) than in rural areas (OR: 3.67).

Conclusion

The findings reveal a gradual upward alarming trend in CS deliveries with an unequal contribution of significant determinants in urban and rural areas of Bangladesh. Therefore, integrated community-level awareness programs are an urgent need in accordance with the findings on the risks of CS and the benefits of vaginal deliveries in this country.

Consistency of Delivery Mode Increases Chinese Mothers' Maternal Satisfaction: The Effect of Perception of Support from Medical Staff and Mothers' Self-Efficacy

Maternal satisfaction is essential for women. Extant research has focused on how a practical delivery method effects maternal satisfaction. This article tried to explore the effect of the consistency of delivery mode between mothers' expectations and their experience of maternal satisfaction and proposed the mediating effect of the perception of support from medical staff and the moderated mediation effect of maternal self-efficacy. Based on two studies, this article found that the consistency of the delivery mode has a positive effect on maternal satisfaction, and women's perception of support from medical staff mediated the above relationship. The maternal perception of self-efficacy has a moderated mediation effect; specifically, for women with a high level of self-efficacy, the positive effect of the consistency of the delivery mode on maternal satisfaction through perception support from medical staff is stronger. This article highlights the importance of the consistency of the delivery mode between women's expectations and the experience of maternal satisfaction and the psychological mechanisms involved. The results extend the theoretical research on ethics in childbirth and provide implications for improving women's maternal satisfaction from medical staff and themselves.

The Inconsistency Between Women's Preference and Actual Mode of Delivery in China: Findings From a Prospective Cohort Study

Background

Previous studies have found that the rates of cesarean preference were much lower than the actual rates of cesarean births in China. We aimed to observe this inconsistency between preferred and actual modes of delivery and the factors associated with the inconsistency.

Methods

We conducted a prospective cohort study at the maternity hospital with the largest number of deliveries in Beijing. We collected data through a questionnaire applied in the outpatient department, and medical records from the hospital's information system. Unconditional logistic regression was used to identify factors influencing the inconsistency between preferred and actual delivery mode.

Results

The rates of actual cesarean section and of cesarean preference were 41 and 17%, respectively (χ² = 82.9, P < 0.0001). The overall inconsistency rate was 31%, with 119 women preferred vaginal delivery but experienced cesarean section, accounting for 67% women undergoing cesarean section. Risk factors for this inconsistency between preferred vaginal delivery and actual cesarean section included: maternal obesity, receiving assisted reproduction, having an abnormal amniotic fluid volume, and fetal distress. Pre-labor rupture of membranes was a unique factor associated with such inconsistency between cesarean section preference and vaginal delivery at delivery.

Conclusions

The inconsistent rate between preferred delivery at late pregnancy and actual delivery is high in China. Further research is needed to understand how to lower cesarean rates in China, taking maternal preferences for vaginal deliveries into account.

Worldwide prevalence of suicide attempt in pregnant and postpartum women: a meta-analysis of observational studies

PURPOSE

Past suicide attempts (SA) are a major contributor to suicide. The prevalence of SA in pregnant and postpartum women varied significantly across studies. Therefore, this meta-analysis was conducted to examine the prevalence of SA and its mediating factors in this population.

METHODS

Relevant articles published in PubMed, EMBASE, Web of Science, PsycINFO, Medline complete, Chinese National Knowledge Infrastructure database (CNKI), Chinese Wanfang and Chongqing VIP database were systematically searched from inception to March 28, 2019. Titles, abstracts and full texts were reviewed independently by three researchers. Studies were included if they reported data on SA prevalence or provided relevant data that enabled the calculation of SA prevalence. Data were extracted by two researchers and checked by one senior researcher. The random-effects model was used to analyze data by the CMA 2.0 and Stata 12.0, with the high degree of statistical heterogeneity present. The primary outcomes were prevalence of SA with 95% CI during pregnancy and during the first-year postpartum.

RESULTS

Fourteen studies covering 6,406,245 pregnant and postpartum women were included. The pooled prevalence of SA was 680 per 100,000 (95% confidence interval 0.10-4.69%) during pregnancy and 210 per 100,000 (95% confidence interval 0.01-3.21%) during the first-year postpartum. Data source was significantly associated with prevalence of SA in the subgroup analysis (pregnancy, p < 0.001; the first-year postpartum, p = 0.013).

CONCLUSION

The prevalence of SA is not high in pregnant and postpartum women. Due to the potential loss of life and negative impact of SA on health outcomes, however, careful screening and effective preventive measures should be implemented for this population.

Sex Dimorphic Associations of Gestational Diabetes Mellitus With Cord Plasma Fatty Acid Binding Protein 4 and Estradiol

Fatty acid binding protein 4 (FABP4) has been associated with insulin resistance. Gestational diabetes mellitus (GDM) impairs fetal insulin sensitivity. Female newborns are more insulin resistant than male newborns. We sought to evaluate the association between GDM and cord blood FABP4, and explore potential sex dimorphic associations and the roles of sex hormones. This was a nested case-control study in the Shanghai Birth Cohort, including 153 pairs of newborns in GDM vs. euglycemic pregnancies matched by infant sex and gestational age at delivery. Cord plasma FABP4, leptin, total and high-molecular-weight adiponectin, testosterone and estradiol concentrations were measured. Adjusting for maternal and neonatal characteristics, cord plasma FABP4 (Mean ± SD: 27.0 ± 19.6 vs. 18.8 ± 9.6 ng/mL, P=0.045) and estradiol (52.0 ± 28.6 vs. 44.2 ± 26.6, ng/mL, P=0.005) concentrations were higher comparing GDM vs. euglycemic pregnancies in males, but similar in females (all P>0.5). Mediation analyses showed that the positive association between GDM and cord plasma FABP4 in males could be partly mediated by estradiol (P=0.03), but not by testosterone (P=0.72). Cord plasma FABP4 was positively correlated with total adiponectin in females (r=0.17, P=0.053), but the correlation was in the opposite direction in males (r=-0.11, P=0.16) (test for difference in r, P=0.02). Cord plasma FABP4 was not correlated with leptin in both sexes. The study is the first to demonstrate sex-dimorphic associations between GDM and cord plasma FABP4 or estradiol, and between FABP4 and adiponectin in newborns. GDM may affect fetal circulating FABP4 and estradiol levels in males only.

Factors associated with childbirth self-efficacy: a multicenter cross-sectional study in China

OBJECTIVE

Childbirth self-efficacy is an important indicator of a woman's choice of mode of delivery, and has been found to be closely related to adverse perinatal outcomes. This study was conducted to evaluate childbirth self-efficacy and its influencing factors among pregnant Chinese women.

DESIGN

A multicenter cross-sectional study.

METHODS

Pregnant women were recruited by using a convenience sample in four maternal and child healthcare hospitals, one each from four cities in China between May and June 2018. Women with a singleton pregnancy, aged 18 years and older, and able to read and write the Chinese language were included. Trained investigators used a structured self-administrated questionnaire to collect data. EpiData 3.1 was used to prepare the database, and SAS 9.2 was used for statistical analysis. A one-way ANOVA test or independent sample t-tests were used to test the between-group differences in childbirth self-efficacy scores, as appropriate. Multivariate linear regression analyses were conducted to examine childbirth self-efficacy of the pregnant women, and the socio-demographic and obstetric factors that influence childbirth self-efficacy.

FINDINGS

A total of 1,796 pregnant Chinese women with singleton pregnancies were recruited into this study. The average childbirth self-efficacy score of the participants was 14.42 (standard deviation = 2.80); 9.35% of the participants scored ≤ 10 points, while 22.49% got more than 15 points. Multivariate linear regression analysis revealed that higher childbirth self-efficacy was significantly associated with younger age (ß = -0.05, P<0.01), lower body mass index (BMI) (ß = -0.06, P <0.01), receiving prenatal education (ß = 0.47, P <0.01), performing physical activity 6-7 times per week (ß = 0.47, P = 0.03), and fair (ß = 0.57, P <0.01) or good (ß = 1.08, P <0.01) self-rated health status.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Childbirth self-efficacy was low among pregnant Chinese women. Women with older age, higher BMI, and worse self-rated health status had lower childbirth self-efficacy. On the other hand, women who frequently exercised, had some prenatal education, and had better self-rated health showed higher childbirth self-efficacy during pregnancy. Interventions concentrating on improving childbirth self-efficacy in China should focus on prenatal education for expectant mothers, and more attention should be given to pregnant women who are older, obese, are less physically active, and are in poor health.

Effect of a Text Messaging-Based Educational Intervention on Cesarean Section Rates Among Pregnant Women in China: Quasirandomized Controlled Trial

Background

Consensus exists that appropriate regional cesarean rates should not exceed 15% of births, but China’s cesarean rate exceeds 50% in some areas, prompting numerous calls for its reduction. At present, China’s 2016 two-child policy has heightened the implications of national cesarean section trends.

Objective

This study leveraged pervasive cellular phone access amongst Chinese citizens to test the effect of a low-cost and scalable prenatal advice program on cesarean section rates.

Methods

Participants were pregnant women presenting for antenatal care at a clinic in Xi’an, China. Assignment was quasirandomized and utilized factorial assignment based on the expecting mother’s birthday. Participants were assigned to one of the following four groups, with each receiving a different set of messages: (1) a comparison group that received only a few “basic” messages, (2) a group receiving messages primarily regarding care seeking, (3) a group receiving messages primarily regarding good home prenatal practices, and (4) a group receiving text messages of all groups. Messages were delivered throughout pregnancy and were tailored to each woman’s gestational week. The main outcome was the rates of cesarean delivery reported in the intervention arms. Data analysts were blinded to treatment assignment.

Results

In total, 2115 women completed the trial and corresponding follow-up surveys. In the unadjusted analysis, the group receiving all texts was associated with an odds ratio of 0.77 (P=.06), though neither the care seeking nor good home prenatal practice set yielded a relevant impact. Adjusting for potentially confounding covariates showed that the group with all texts sent together was associated with an odds ratio of 0.67 (P=.01). Notably, previous cesarean section evoked an odds ratio of 11.78 (P<.001), highlighting that having a cesarean section predicts future cesarean section in a subsequent pregnancy.

Conclusions

Sending pregnant women in rural China short informational messages with integrated advice regarding both care-seeking and good home prenatal practices appears to reduce women’s likelihood of undergoing cesarean section. Reducing clear medical indications for cesarean section seems to be the strongest potential pathway of the effect. Cesarean section based on only maternal request did not seem to occur regularly in our study population. Preventing unnecessary cesarean section at present may have a long-term impact on future cesarean section rates.

The effect of initiating neuraxial analgesia service on the rate of cesarean delivery in Hubei, China: a 16-month retrospective study

BACKGROUND

No Pain Labor &Delivery (NPLD) is a nongovernmental project to increase access to safe neuraxial analgesia through specialized training. This study explores the change in overall cesarean delivery (CD) rate and maternal request CD(MRCD) rate in our hospital after the initiation of neuraxial analgesia service (NA).

METHODS

NA was initiated in May 1st 2015 by the help of NPLD. Since then, the application of NA became a routine operation in our hospital, and every parturient can choose to use NA or not. The monthly rates of NA, CD, MRCD, multiparous women, intrapartum CD, episiotomy, postpartum hemorrhage (PPH), operative vaginal delivery and neonatal asphyxia were analyzed from January 2015 to April 2016.

RESULTS

The rate of NA in our hospital was getting increasingly higher from 26.1% in May 2015 to 44.6% in April 2016 (p < 0.001); the rate of CD was 48.1% (3577/7360) and stable from January to May 2015 (p>0.05), then decreased from 50.4% in May 2015 to 36.3% in April 2016 (p < 0.001); the rate of MRCD was 11.4% (406/3577) and also stable from January to May 2015 (p>0.05), then decreased from 10.8% in May 2015 to 5.7% in April 2016 (p < 0.001). At the same time, the rate of multiparous women remained unchanged during the 16 month of observation (p>0.05). There was a negative correlation between the rate of NA and rate of overall CD, r = - 0.782 (95%CI [- 0.948, - 0.534], p<0.001), and between the utilization rate of NA and rate of MRCD, r = - 0.914 (95%CI [- 0.989, - 0.766], p<0.001). The rates of episiotomy, PPH, operative vaginal delivery and neonatal asphyxia in women who underwent vaginal delivery as well as the rates of intrapartum CD, neonatal asphyxia, and PPH in women who underwent CD remained unchanged, and there was no correlation between the rate of NA and anyone of those rates from January 1st 2015 to April 30th 2016 (p>0.05).

CONCLUSIONS

Our study shows that the rates of CD and MRCD in our department were significantly decreased from May 1st 2015 to April 30th 2016, which may be due to the increasing use of NA during vaginal delivery with the help of NPLD.

Delivery mode-associated gut microbiota in the first 3 months of life in a country with high obesity rates: A descriptive study

Delivery methods during childbirth and their related gut microbiota profiles have important impacts on health later in life, they can contribute to the development of diseases such as obesity, whose highest prevalence rate is found among the Mexican child population. Coincidentally, Mexico has one of the highest global average annual rate increase in cesarean births (C-section). Since Mexico leads the world in childhood obesity, studying the relationship between childbirth delivery methods and gut microbiota profiles in this vulnerable population may be used to identify early risk factors for obesity in other developed and developing countries. The objective of this study is to determine the association between child delivery method and gut microbiota profiles in healthy Mexican newborns.Fecal samples of 57 term infants who participated in a randomized clinical trial in 2013 to study the safety of Agave fructans in newborns, were used in this study. DNA samples were extracted and used to characterize the microbiota composition using high-throughput 16S rRNA gene sequencing. The samples were further divided based on childbirth delivery method, as well as early diet. Gut microbiota profiles were determined and analyzed using cluster analysis followed by multiple correspondence analysis.An unusual high abundance of Proteobacteria was found in the gut microbiota of all Mexican infants studied, regardless of delivery method. Feces from infants born by C-section had low levels of Bacteroidetes, high levels of Firmicutes, especially Clostridium and Enterococcus, and a strikingly high ratio of Firmicutes/Bacteroidetes (F:B). Profiles enriched in Bacteroidetes and low F:B ratios, were strongly associated with vaginal delivery.The profile of gut microbiota associated with feces from Mexican infants born by C-section, may be added to the list of boosting factors for the worrying obesity epidemic in Mexico.

Reducing caesarean section rate in an urban hospital serving women attending privately in India - a quality improvement initiative

BACKGROUND

In line with global trends, India has witnessed a sharp rise in caesarean section (CS) deliveries, especially in the private sector. Despite the urgent need for change, there are few published examples of private hospitals that have successfully lowered their CS rates. Our hospital, serving private patients too, had a CS rate of 79% in 2001. Care was provided by fee-for-service visiting consultant obstetricians without uniform clinical protocols and little clinical governance. Consultants attributed high CS rate to case-mix and maternal demand and showed little inclination for change. We attempted to reduce this rate with the objective of improving the quality of our care and demonstrating that CS could be safely lowered in the private urban Indian healthcare setting.

METHODS

We hired full-time salaried consultants and began regular audit of CS cases. When this proved inadequate, we joined an improvement collaborative in 2011 and dedicated resources for quality improvement. We adopted practice guidelines, monitored outcomes by consultant, improved labour ward support, strengthened antenatal preparation, and moved to group practice among consultants.

RESULTS

Guidelines ensured admissions in active labour and reduced CS (2011 to 2016) for foetal heart rate abnormalities (23 to 5%; p < 0.001) and delayed progress (19 to 6%; p < 0.001) in low-risk first-birth women. Antenatal preparation increased trial of labour, even among women with prior CS (28 to 79%; p < 0.001). Group practice reduced time pressure and stress, with a decline in CS (52 to 18%; p < 0.001) and low-risk first-birth CS (48 to 12%; p < 0.001). Similar CS rates were maintained in 2017 and 2018. Measures of perinatal harm including post-partum haemorrhage, 3rd-4th degree tears, shoulder dystocia, and Apgar < 7 at 5 min were within acceptable ranges (13, 3, 2% and 3 per thousand respectively in 2016-18,).

CONCLUSIONS

It is feasible to substantially reduce CS rate in private healthcare setting of a middle-income country like India. Ideas such as moving to full-time attachment of consultants, joining a collaborative, improving labour ward support, providing resources for data collection, and perseverance could be adopted by other hospitals in their own journey of moving towards a medically justifiable CS rate.

A cluster-randomized field trial to reduce cesarean section rates with a multifaceted intervention in Shanghai, China

BACKGROUND

Cesarean section (CS) rate has risen dramatically and stayed at a very high level in China over the past two to three decades. Given the short- and long-term adverse effects of CS, effective strategies are needed to reduce unnecessary CS. We aimed to evaluate whether a multifaceted intervention would decrease the CS rate in China.

METHODS

We carried out a cluster-randomized field trial with a multifaceted intervention in Shanghai, China, from 2015 to 2017. A total of 20 hospitals were randomly allocated into an intervention or a control group. The intervention consisted of more targeted health education to pregnant women, improved hospital CS policy, and training of midwives/doulas for 8 months. The study included a baseline survey, the intervention, and an evaluation survey. The primary outcome was the changes of overall CS rate from the pre-intervention to the post-intervention period. A subgroup analysis stratified by the Robson classification was also conducted to examine the CS change among women with various obstetric characteristics.

RESULTS

A total of 10,752 deliveries were randomly selected from the pre-intervention period and 10,521 from the post-intervention period. The baseline CS rates were 42.5% and 41.5% in the intervention and control groups, respectively, while the post-intervention CS rates were 43.4% and 42.4%, respectively. Compared with the control group, the intervention did not significantly reduce the CS rate (adjusted OR = 0.92; 95% CI 0.73, 1.15). Similar results were obtained in subgroup analyses stratified by the risk level of pregnancy, maternal age, number of previous CS, or parity. Scarred uterus and maternal request remained the primary reasons for CS after the interventions in both groups. The intervention did not alter the perinatal outcomes (adjusted change of risk score = - 0.06; 95%CI - 0.43, 0.31).

CONCLUSIONS

A multifaceted intervention including more targeted prenatal health education, improved hospital CS policy, and training of midwives/doulas, did not significantly reduce the CS rate in Shanghai, China. However, our experience in implementing a multifaceted intervention may provide useful information to other similar areas with high CS use.

TRIAL REGISTRATION

This trial was registered at the Chinese Clinical Trial Registry (www.chictr.org.cn) (ChiCTR-IOR-16009041) on 17 August 2016.

Effects of Migration on Infant and Maternal Health in China

We assess the association between maternal migrant status and health outcomes in China, which has one of the world’s largest migrant populations. Health records from the Shanghai First Maternity and Infant Hospital from January 1, 2013, to June 30, 2017, were used to analyze 104 681 live births for Shanghai native-born and migrant women based on International Classification of Diseases, Tenth Revision diagnosis codes and demographic data. Regression analysis including propensity score matching was conducted to investigate the association between maternal migrant status and adverse infant birth outcomes (fetal disease, congenital malformation, neonatal disease) and maternal health after controlling for pregnancy status and socioeconomic factors. The results demonstrate that migrant women had statistically significant increased odds (9.1%-10%, P < .001) of having infants with adverse health outcomes compared with their urban counterparts and that migrant mothers have less likelihood of pregnancy complications and gestational diabetes mellitus. Our results show the mixed effects of migration on infant and maternal health may be a possible outcome of China’s Hukou system that often represents an important barrier in accessing prenatal health care by migrant women. Current reforms that improve access to prenatal health care services for migrant women may enhance the health outcomes of their infants.

The effectiveness of financial intervention strategies for reducing caesarean section rates: a systematic review

Background

The increasing trend of Caesarean section (CS) in childbirth has become a global public health challenge. Previous studies have proposed financial intervention strategies for reducing CS rates by limiting caesarean delivery on maternal request (CDMR). This study synthesizes such strategies while evaluating their effectiveness.

Methods

The sources of data for this study are Cochrane Library, PubMed, EMBASE, and CINAHL. The publication period included in this study is from January 1991 to November 2018. The financial intervention strategies are divide into two categories: healthcare provider interventions and patient interventions. Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) was employed to assess the risk of bias of included studies. The outcome of each study was evaluated with Grades of Recommendation, Assessment, Development and Evaluation (GRADE) through the GRADEpro Guideline Development Tool software.

Results

Nine studies were included in this systematic review: five with high certainty evidence (HCE), three with moderate certainty evidence (MCE), and one with low certainty evidence (LCE). Of the nine studies, seven are centered on the effect of provider-side interventions. Three of the HCE studies found that the diagnosis-related group payment system, risk-adjusted capitation, and equalizing fee for both facilities and physicians were effective intervention strategies. One HCE and one MCE study showed that only equalizing facility fees between vaginal and CS deliveries in healthcare service settings had no significant effect on reducing the CS rate. The MCE study showed that case payment had a negative effect on reducing the CS rates. One LCE study revealed that the effect of a global budget system was uncertain, and one HCE and one MCE study focused on combining both provider and patient-side interventions. However, equalizing fees for vaginal and CS deliveries and a co-payment policy for CDMRs failed to reduce the CS rate.

Conclusions

The effectiveness of risk-adjusted payment methods appears promising and should be the subject of further research. Financial interventions should consider stakeholders’ characteristics, especially the personal interests of doctors. Finally, high-quality randomized control trials and comparative studies on different financial intervention methods are needed to confirm or refute previous studies’ outcomes.

Evidence of overuse? Patterns of obstetric interventions during labour and birth among Australian mothers

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.

How is women's demand for caesarean section measured? A systematic literature review

Background

Caesarean section rates are increasing worldwide, and since the 2000s, several researchers have investigated women’s demand for caesarean sections.

Question

The aim of this article was to review and summarise published studies investigating caesarean section demand and to describe the methodologies, outcomes, country characteristics and country income levels in these studies.

Methods

This is a systematic review of studies published between 2000 and 2017 in French and English that quantitatively measured women’s demand for caesarean sections. We carried out a systematic search using the Medline database in PubMed.

Findings

The search strategy identified 390 studies, 41 of which met the final inclusion criteria, representing a total sample of 3 774 458 women. We identified two different study designs, i.e., cross-sectional studies and prospective cohort studies, that are commonly used to measure social demand for caesarean sections. Two different types of outcomes were reported, i.e., the preferences of pregnant or non-pregnant women regarding the method of childbirth in the future and caesarean delivery following maternal request. No study measured demand for caesarean section during the childbirth process. All included studies were conducted in middle- (n = 24) and high-income countries (n = 17), and no study performed in a low-income country was found.

Discussion

Measuring caesarean section demand is challenging, and the structural violence leading to demand for caesarean section during childbirth while in the labour ward remains invisible. In addition, the caesarean section demand in low-income countries remains unclear due to the lack of studies conducted in these countries.

Conclusion

We recommend conducting prospective cohort studies to describe the social construction of caesarean section demand. We also recommend conducting studies in low-income countries because demand for caesarean sections in these countries is rarely investigated.

Socioeconomic and demographic factors associated with caesarean section delivery in Southern Ghana: evidence from INDEPTH Network member site

BACKGROUND

In recent years, caesarean section rates continue to evoke worldwide concern because of their steady increase, lack of consensus on the appropriate caesarean section rate and the associated short- and long-term risks. This study sought to identify the rate of caesarean section and associated factors in two districts in rural southern Ghana.

METHODS

Pregnancy, birth, and socio-demographic information of 4948 women who gave birth between 2011 and 2013 were obtained from the database of Dodowa Health and Demographic Surveillance System. The rate of C-section was determined and the associations between independent and dependent variables were explored using logistic regression. The analyses were done in STATA 14.2 at 95% confidence interval.

RESULTS

The overall C-section rate for the study period was 6.59%. Women aged 30-34 years were more than twice likely to have C-section compared to those < 20 year (OR: 2.16, 95% CI: 1.20-3.90). However, women aged 34 years and above were more than thrice likely to undergo C-section compared to those < 20 year (OR: 3.73, 95% CI: 1.45-5.17). The odds of having C-section was 65 and 79% higher for participants with Primary and Junior High level schooling respectively (OR: 1.65, 95% CI: 1.08-2.51, OR:1.79, 95%CI: 1.19-2.70). The likelihood of having C-section delivery reduced by 60, 37, and 35% for women with parities 2, 3 and 3+ respectively (OR:0.60, 95% CI: 0.43-0.83, OR: 0.37, 95% CI: 0.25-0.56, OR:0.35, 95% CI: 0.25-0.54). There were increased odds of 36, 52, 83% for women who belong to poorer, middle, and richer wealth quintiles respectively (OR: 1.36, 95%CI: 0.85-2.18, OR: 1.52, 95% CI: 0.97-2.37, OR: 1.83, 95% CI: 1.20-2.80). Participants who belonged to the richest wealth quintile were more than 2 times more likely to have C-section delivery (OR: 2.14, 95%CI: 1.43-3.20). The odds of having C-section delivery reduced by 76% for women from Ningo-Prampram district (OR: 0.76, 95% CI: 0.59.0.96). Women whose household heads have Junior High level and above of education were 45% more likely to have C-section delivery (OR: 1.45, 95% CI: 1.09-1.93).

CONCLUSION

Age of mother, educational level, parity, household socioeconomic status, district of residence, and level of education of household head are associated with caesarean section delivery.

Interventions to reduce unnecessary caesarean sections in healthy women and babies

Optimising the use of caesarean section (CS) is of global concern. Underuse leads to maternal and perinatal mortality and morbidity. Conversely, overuse of CS has not shown benefits and can create harm. Worldwide, the frequency of CS continues to increase, and interventions to reduce unnecessary CSs have shown little success. Identifying the underlying factors for the continuing increase in CS use could improve the efficacy of interventions. In this Series paper, we describe the factors for CS use that are associated with women, families, health professionals, and health-care organisations and systems, and we examine behavioural, psychosocial, health system, and financial factors. We also outline the type and effects of interventions to reduce CS use that have been investigated. Clinical interventions, such as external cephalic version for breech delivery at term, vaginal breech delivery in appropriately selected women, and vaginal birth after CS, could reduce the frequency of CS use. Approaches such as labour companionship and midwife-led care have been associated with higher proportions of physiological births, safer outcomes, and lower health-care costs relative to control groups without these interventions, and with positive maternal experiences, in high-income countries. Such approaches need to be assessed in middle-income and low-income countries. Educational interventions for women should be complemented with meaningful dialogue with health professionals and effective emotional support for women and families. Investing in the training of health professionals, eliminating financial incentives for CS use, and reducing fear of litigation is fundamental. Safe, private, welcoming, and adequately resourced facilities are needed. At the country level, effective medical leadership is essential to ensure CS is used only when indicated. We conclude that interventions to reduce overuse must be multicomponent and locally tailored, addressing women's and health professionals' concerns, as well as health system and financial factors.

Prevalence of and reasons for women's, family members', and health professionals' preferences for cesarean section in China: A mixed-methods systematic review

BACKGROUND

China has witnessed a rapid increase of cesarean section (CS) rates in recent years. Several non-clinical factors have been cited as contributing to this trend including maternal request and perceived convenience. We aimed to assess preferences for mode of delivery and reasons for preferences for CS in China to inform the development of future interventions to mitigate unnecessary CSs, which are those performed in the absence of medical indications.

METHODS AND FINDINGS

We conducted a mixed-methods systematic review and included longitudinal, cross-sectional, and qualitative studies in mainland China, Hong Kong, and Taiwan that investigated preferences for mode of delivery among women and family members and health professionals, and the reasons underlying such preferences. We searched MEDLINE/PubMed, Embase, CINAHL, POPLINE, PsycINFO, Global Health Library, and one Chinese database (CNKI) using a combination of the key terms 'caesarean section', 'preference', 'choice', 'knowledge', 'attitude', 'culture', 'non-clinical factors', and 'health professionals-patient relations' between 1990 and 2018 without language restriction. Meta-analysis of quantitative studies and meta-synthesis of qualitative studies were applied. We included 66 studies in this analysis: 47 quantitative and 19 qualitative. For the index pregnancy, the pooled proportions of preference for CS reported by women in longitudinal studies were 14% in early or middle pregnancy (95% CI 12%-17%) and 21% in late pregnancy (95% CI 15%-26%). In cross-sectional studies, the proportions were 17% in early or middle pregnancy (95% CI 14%-20%), 22% in late pregnancy (95% CI 18%-25%), and 30% postpartum (95% CI 19%-40%). Women's preferences for CS were found to rise as pregnancy progressed (preference change across longitudinal studies: mean difference 7%, 95% CI 1%-13%). One longitudinal study reported that the preference for CS among women's partners increased from 8% in late pregnancy to 17% in the immediate postpartum period. In addition, 18 quantitative studies revealed that some pregnant women, ranging from 4% to 34%, did not have a straightforward preference for a mode of delivery, even in late pregnancy. The qualitative meta-synthesis found that women's perceptions of CS as preferable were based on prioritising the baby's and woman's health and appeared to intensify through interactions with the health system. Women valued the convenience of bypassing labour because of fear of pain, antagonistic relations with providers, and beliefs of deteriorating quality of care during labour and vaginal birth, fostering the feeling that CS was the safest option. Health professionals' preference for CS was influenced by financial drivers and malpractice fears. This review has some limitations, including high heterogeneity (despite subgroup and sensitivity analysis) in the quantitative analysis, and the potential for over-reporting of women's preferences for CS in the qualitative synthesis (due to some included studies only including women who requested CS).

CONCLUSIONS

Despite a minority of women expressing a preference for CS, individual, health system, and socio-cultural factors converge, contributing to a high CS rate in mainland China, Hong Kong, and Taiwan. In order to reduce unnecessary CSs, interventions need to address all these non-clinical factors and concerns.

Non-clinical interventions for reducing unnecessary caesarean section

BACKGROUND

Caesarean section rates are increasing globally. The factors contributing to this increase are complex, and identifying interventions to address them is challenging. Non-clinical interventions are applied independently of a clinical encounter between a health provider and a patient. Such interventions may target women, health professionals or organisations. They address the determinants of caesarean births and could have a role in reducing unnecessary caesarean sections. This review was first published in 2011. This review update will inform a new WHO guideline, and the scope of the update was informed by WHO's Guideline Development Group for this guideline.

OBJECTIVES

To evaluate the effectiveness and safety of non-clinical interventions intended to reduce unnecessary caesarean section.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers in March 2018. We also searched websites of relevant organisations and reference lists of related reviews.

SELECTION CRITERIA

Randomised trials, non-randomised trials, controlled before-after studies, interrupted time series studies and repeated measures studies were eligible for inclusion. The primary outcome measures were: caesarean section, spontaneous vaginal birth and instrumental birth.

DATA COLLECTION AND ANALYSIS

We followed standard methodological procedures recommended by Cochrane. We narratively described results of individual studies (drawing summarised evidence from single studies assessing distinct interventions).

MAIN RESULTS

We included 29 studies in this review (19 randomised trials, 1 controlled before-after study and 9 interrupted time series studies). Most of the studies (20 studies) were conducted in high-income countries and none took place in low-income countries. The studies enrolled a mixed population of pregnant women, including nulliparous women, multiparous women, women with a fear of childbirth, women with high levels of anxiety and women having undergone a previous caesarean section.Overall, we found low-, moderate- or high-certainty evidence that the following interventions have a beneficial effect on at least one primary outcome measure and no moderate- or high-certainty evidence of adverse effects.Interventions targeted at women or familiesChildbirth training workshops for mothers alone may reduce caesarean section (risk ratio (RR) 0.55, 95% confidence interval (CI) 0.33 to 0.89) and may increase spontaneous vaginal birth (RR 2.25, 95% CI 1.16 to 4.36). Childbirth training workshops for couples may reduce caesarean section (RR 0.59, 95% CI 0.37 to 0.94) and may increase spontaneous vaginal birth (RR 2.13, 95% CI 1.09 to 4.16). We judged this one study with 60 participants to have low-certainty evidence for the outcomes above.Nurse-led applied relaxation training programmes (RR 0.22, 95% CI 0.11 to 0.43; 104 participants, low-certainty evidence) and psychosocial couple-based prevention programmes (RR 0.53, 95% CI 0.32 to 0.90; 147 participants, low-certainty evidence) may reduce caesarean section. Psychoeducation may increase spontaneous vaginal birth (RR 1.33, 95% CI 1.11 to 1.61; 371 participants, low-certainty evidence). The control group received routine maternity care in all studies.There were insufficient data on the effect of the four interventions on maternal and neonatal mortality or morbidity.Interventions targeted at healthcare professionalsImplementation of clinical practice guidelines combined with mandatory second opinion for caesarean section indication slightly reduces the risk of overall caesarean section (mean difference in rate change -1.9%, 95% CI -3.8 to -0.1; 149,223 participants). Implementation of clinical practice guidelines combined with audit and feedback also slightly reduces the risk of caesarean section (risk difference (RD) -1.8%, 95% CI -3.8 to -0.2; 105,351 participants). Physician education by local opinion leader (obstetrician-gynaecologist) reduced the risk of elective caesarean section to 53.7% from 66.8% (opinion leader education: 53.7%, 95% CI 46.5 to 61.0%; control: 66.8%, 95% CI 61.7 to 72.0%; 2496 participants). Healthcare professionals in the control groups received routine care in the studies. There was little or no difference in maternal and neonatal mortality or morbidity between study groups. We judged the certainty of evidence to be high.Interventions targeted at healthcare organisations or facilitiesCollaborative midwifery-labourist care (in which the obstetrician provides in-house labour and delivery coverage, 24 hours a day, without competing clinical duties), versus a private practice model of care, may reduce the primary caesarean section rate. In one interrupted time series study, the caesarean section rate decreased by 7% in the year after the intervention, and by 1.7% per year thereafter (1722 participants); the vaginal birth rate after caesarean section increased from 13.3% before to 22.4% after the intervention (684 participants). Maternal and neonatal mortality were not reported. We judged the certainty of evidence to be low.We studied the following interventions, and they either made little or no difference to caesarean section rates or had uncertain effects.Moderate-certainty evidence suggests little or no difference in caesarean section rates between usual care and: antenatal education programmes for physiologic childbirth; antenatal education on natural childbirth preparation with training in breathing and relaxation techniques; computer-based decision aids; individualised prenatal education and support programmes (versus written information in pamphlet).Low-certainty evidence suggests little or no difference in caesarean section rates between usual care and: psychoeducation; pelvic floor muscle training exercises with telephone follow-up (versus pelvic floor muscle training without telephone follow-up); intensive group therapy (cognitive behavioural therapy and childbirth psychotherapy); education of public health nurses on childbirth classes; role play (versus standard education using lectures); interactive decision aids (versus educational brochures); labourist model of obstetric care (versus traditional model of obstetric care).We are very uncertain as to the effect of other interventions identified on caesarean section rates as the certainty of the evidence is very low.

AUTHORS' CONCLUSIONS

We evaluated a wide range of non-clinical interventions to reduce unnecessary caesarean section, mostly in high-income settings. Few interventions with moderate- or high-certainty evidence, mainly targeting healthcare professionals (implementation of guidelines combined with mandatory second opinion, implementation of guidelines combined with audit and feedback, physician education by local opinion leader) have been shown to safely reduce caesarean section rates. There are uncertainties in existing evidence related to very-low or low-certainty evidence, applicability of interventions and lack of studies, particularly around interventions targeted at women or families and healthcare organisations or facilities.

The impact of health sector evolution plan on hospitalization and cesarean section rates in Iran: an interrupted time series analysis

Objective

To investigate the effect of the health sector evolution plan (HSEP) on hospitalization and cesarean section (C-section) rates in Kermanshah province in the western region of Iran.

Design

Interrupted time series analysis.

Setting

Hospital care system in Kermanshah province.

Study Participants

Fifteen hospitals affiliated to Ministry of Health and Medical Education (MoHME) in Kermanshah province.

Intervention(s)

Health sector evolution plan.

Main Outcome Measures

Hospitalization rate and C-section rate.

Results

We observed a statistically significant increase in the hospitalization rate (12.9 hospitalizations per 10 000 population, P < 0.001) in the first month after the implementation of the HSEP. Compared with the monthly trend in hospitalization rate before the intervention, we found a significant increase of 0.70 hospitalizations per 10 000 population (P < 0.001) in monthly trend in hospitalization rate after the HSEP. Although the proportion of C-section from total deliveries decreased by 11% (P = 0.044) in the first month after the implementation of the HSEP, the proportion of C-section from total deliveries increased at the rate of 0.0017% (P = 0.001) per month during post-intervention period.

Conclusion

We found an increase in the hospitalization rate after the intervention of HSEP. Although the C-section rate in the first month after the HSEP decreased, we observed an increasing trend in C-section rate over the study period; this implies that the HSEP did not promote vaginal delivery in Iran, which is outlined as one of the objectives of the intervention.

Association Between Mode of Delivery and Risk of Infection in Early Childhood: A Cohort Study

BACKGROUND

Infections are the leading cause of morbidity and mortality in children. Caesarean section as a potential risk factor for infection has recently gained interest. Delivery by caesarean section has increased greatly, with nonmedical reasons playing an increasing role. We aimed to analyze the association between mode of delivery and hospitalizations because of infection and symptoms of infection at home in early childhood.

METHODS

A cohort study, based on the Odense Child Cohort, following infants from gestation until a mean age of 3.5 years. Data on hospitalization because of infections were collected from the Danish National Patient Registry. Data on symptoms of infection at home were collected via a text message-based questionnaire.

RESULTS

A total of 1921 children were born by vaginal delivery, 283 by elective caesarean section and 227 by acute caesarean section. An adjusted regression model showed an incidence rate ratio for hospitalizations because of infection in children born by elective caesarean section compared with children born by vaginal delivery of 1.45 (95% confidence interval: 1.16-1.80; P = 0.001). The analyses on symptoms of infection at home found no associations between any symptom of infection and mode of delivery. Symptom-specific subanalyses showed contrasting results.

CONCLUSIONS

Mode of delivery showed a strong association to hospitalization because of infectious disease during early childhood. Overall, no association was present between rate of symptoms of infection at home and mode of delivery.

Individual and community factors associated with indications of caesarean delivery in Southern Nigeria: Pooled analyses of 2003-2013 Nigeria demographic and health surveys

In this study, the researcher examines associated individual and community factors of indications of caesarean delivery in Southern Nigeria. Data were pooled from 2003-2013 Nigeria Demographic and Health Surveys. Analyses were performed using Stata 12. The multilevel mixed-effects logistic regression was applied. Indications of caesarean delivery were 4.9% over the studied period. Maternal age, parity, education, and household wealth were significantly associated with indications of caesarean delivery. Community effects on indications of caesarean delivery were significant. A public health education programme is needed to address aversion to caesarean sections among those who may have medical need for caesarean delivery.

Tanzanian Mothers' Cultural Beliefs and Misinformation Regarding the Reasons for Their Cesarean Sections

BACKGROUND

In Tanzania, cesarean section (CS) rates have been steadily increasing, yet little is known about mothers' understanding of the medical rationale for their CSs.

AIM

To identify mothers' cultural understandings of the rationale for their CSs.

METHODS

Design: A qualitative descriptive design was employed.

Setting: A government hospital in the western region in Tanzania.

Participants: A total of 117 mothers were interviewed using convenience sampling post CS.

FINDINGS

Forty percent of the mothers were younger than 18 years, with more than 50% having had five or more live babies. Among multigravida women, 40.2% had had one or more previous CSs.

The emergent themes were lack of dietary knowledge, use of local herbs, delays in coming to hospital, avoiding stressful labor pains and no ability to exercise, and no personal preferences of “push or go for an operation.”

CONCLUSION

Pregnant women in Tanzania need improved health education to make informed choices about childbirth and be involved all processes of antepartum care decision making to achieve optimal birth outcomes.

Effect of second child intent on delivery mode after Chinese two child policy implementation: a cross sectional and prospective observational study of nulliparous women in Chongqing

OBJECTIVES

To assess the influence of second child intent on the delivery preferences and final delivery modes of nulliparous women, particularly caesarean delivery on maternal request (CDMR), after implementation of China's two child policy.

DESIGN

Cross sectional and prospective observational study.

SETTING

A tertiary teaching hospital in Chongqing, China.

PARTICIPANTS

1000 low risk nulliparous women were initially involved, and were divided into two groups based on their intent on having a second child. 814 women who completed all interviews were analysed.

MAIN OUTCOME MEASURES

Preferred mode of delivery in second trimester and at admission; final delivery mode, CDMR.

RESULTS

814 women who completed all interviews were analysed, in whom 51.2% intended to have a second child. The preference for caesarean delivery (CD) at the second trimester between the intent and no intent group was 6.2% versus 17.9% (adjusted RR 0.35, 95% CI 0.20 to 0.63) and increased to 24.2% versus 37.3% (adjusted RR 0.65, 95% CI 0.45 to 0.94) at admission, respectively. The overall CD rates between the two groups were 41.0% versus 50.4% (adjusted RR 0.84, 95% CI 0.60 to 1.18), and the CDMR rates were 16.7% versus 29.0% (adjusted RR 0.56, 95% CI 0.37 to 0.86), respectively.

CONCLUSIONS

Women who intend to have a second child are less likely to request a CD, and high rates of CD and CDMR in nulliparous women may have decreased after implementation of China's two child policy.

Large reductions in cesarean delivery rates in China: a qualitative study on delivery decision-making in the era of the two-child policy

Background

In 2010, China’s cesarean delivery (CD) rates increased to one of the highest in the world, a significant proportion of which were without medical indication. However, recent studies have indicated some declines, coinciding with national and local efforts to promote vaginal birth, as well as the relaxation of the one-child policy. Considering these trends, we aimed to qualitatively explore attitudes towards childbirth and experiences of delivery decision-making among women and physicians.

Methods

Semi-structured interviews were conducted with 45 postpartum women and 7 healthcare providers at one county-level and one provincial-level maternity hospital in Zhejiang Province. We also collected routine data from 2007 to 2016 and observed doctor-patient interactions and hospital facilities as context for the interviews. Interviews were recorded, translated and transcribed into English, and then analyzed using a framework approach.

Results

From 2007 to 2016, cesarean delivery rates at the county-level and provincial-level hospital decreased from 46% to 32% and 68% to 44%, respectively. For low-risk women, vaginal birth was the primary choice of delivery method, encouraged by doctors and nurse-midwives. Elective CD was not as widely accepted, in contrast to previous years. Women were aware of and took into consideration the consequences of CD for future pregnancies. Among those who delivered vaginally, women viewed the existing pain relief methods, epidurals and transcutaneous electrical nerve stimulation, with caution or uncertainty. Even when requested, epidurals were only given under certain circumstances. For multiparas with previous CD, repeat CD remains the norm. Both women and professionals were cautious about vaginal birth after cesarean delivery (VBAC) given the associated risks.

Conclusion

In China, changes in family planning policy and efforts to promote vaginal birth have greatly changed the culture of delivery decision-making, leading to decreased CD rates. This demonstrates the powerful role social factors and public policy can play, and provides a model for other countries with high CD rates. Further research should explore changes in other reproductive decisions during this new multiparous era, particularly across provinces.

Childhood emotional and behavior problems and their associations with cesarean delivery

Objective:

To determine the prevalence of childhood emotional and behavioral problems and examine their associations with cesarean delivery.

Methods:

Our sample consisted of 8,900 preschoolers from 35 kindergartens in four cities in East China. Parents completed the Strengths and Difficulties Questionnaire (SDQ) and provided other information. Children’s emotional and behavioral problems were assessed using five subscales of the SDQ. Mode of delivery was classified as vaginal or cesarean section (CS); in sub-analyses, we divided CS into elective or emergency delivery. Logistic regression was used to examine associations.

Results:

A total of 1,209 (13.6%) children had a total SDQ score within abnormal range; 25.5% had peer problems within abnormal range, 9.0% had abnormal emotional symptoms, 13.9% had abnormal conduct problems, 18.9% had abnormal hyperactivity problems, and 16.2% were rated abnormal in pro-social behavior. Overall, 67.3% of the children who participated were delivered by CS. In fully adjusted analysis, CS was significantly associated with abnormal total SDQ score (OR = 1.27; 95%CI 1.10-1.46; p < 0.05) and pro-social behavior (OR = 1.27; 95%CI 1.12-1.45; p < 0.0001). No significant association was found between CS and risk of having conduct problems (OR 1.13; 95%CI 0.98-1.29), peer problems (OR 1.11; 95%CI 0.99-1.24), hyperactivity (OR 1.02; 95%CI 0.91-1.15), or emotional problems (OR 1.06; 95%CI 0.90-1.24).

Conclusion:

In this sample, CS was associated with risk of behavioral problems, but not with emotional problems. Further research is needed to better understand these associations.

The Elevated Rate of Cesarean Section and Its Contribution to Non-Communicable Chronic Diseases in Latin America: The Growing Involvement of the Microbiota

The current recommendation of the World Health Organization (WHO) regarding cesarean section (C-section) is that this clinical practice should be carried out only under specific conditions, when the health or life of the mother/newborn dyad is threatened, and that its use should not exceed 10-15% of the total deliveries. However, over the last few decades, the frequency of C-section delivery in medium- and high-income countries has rapidly increased worldwide. This review describes the evolution of this procedure in Latin American countries, showing that today more than half of newborns in the region are delivered by C-section. Given that C-section delivery is more expensive than vaginal delivery, its use has increased more rapidly in the private than the public sector; nevertheless, the prevalence of C-section deliveries in the public sector is higher than the WHO's recommendations and continues to increase, representing a growing challenge for Latin America. Although the medium- and long-term consequences of C-section delivery, as opposed to vaginal delivery, on the infant health are unclear, epidemiological studies suggest that it is associated with higher risk of developing asthma, food allergy, type 1 diabetes, and obesity during infancy. These findings are important, as the incidence of these diseases in the Latin American pediatric population is also increasing, particularly obesity. Although the link between these diseases and delivery mode remains controversial, recent studies indicate that the establishment of the gut microbiota is delayed in infants born by C-section during the postnatal period, i.e., during a critical developmental window for the maturation of the newborn's immune system. This delay may favor the subsequent development of inflammatory and metabolic disorders during infancy. Accordingly, from a public health perspective, it is important to slow down and eventually reverse the pattern of increased C-section use in the affected populations.

Factors influencing attempted and completed suicide in postnatal women: A population-based study in Taiwan

The aims of study were to investigate risk factors associated with attempted and completed suicide. This nested case–control study was conducted using the medical and death data of nearly all pregnant women for the period 2002–2012 in Taiwan. A total of 139 cases of attempted suicide and 95 cases of completed suicide were identified; for each case, 10 controls were randomly selected and matched to the cases according to age and year of delivery. A conditional logistic regression model was used. The mean attempted and completed suicide rates were 9.91 and 6.86 per 100,000 women with live births, respectively. Never having married and postpartum depression also increased the risk of attempted suicide (OR = 2.06; 95% CI = 1.09–3.88 and OR = 2.51; 95% CI = 1.10–5.75, respectively) and completed suicide (OR = 20.27; 95% CI = 8.99–45.73 and OR = 21.72; 95% CI = 8.08–58.37, respectively). Other factors for attempted suicide included being widowed or divorced, and having a caesarean delivery or suicide history. Other factors for completed suicide included lower education level, low infant birth weight, and diagnosis of anxiety or mood disorder. These results suggest that people should appropriately assess potential risk factors and provide assistance for postnatal women to reduce the occurrence of suicide events.
