Abstract
BACKGROUND Childhood and adolescent obesity are major, preventable public health concerns. Studies to date are inconclusive regarding an association between caesarean section (CS) delivery and offspring obesity, with fewer studies conducted in late adolescence. This study examined the association between CS delivery, with a specific focus on planned CS, and induction of labour and adolescent body mass index (BMI) and body fat percentage (BF%) at age 17 years. METHODS Data on 8,880 mother-child pairs from the United Kingdom Millennium Cohort Study were analysed. The exposures were mode of delivery (normal vaginal delivery (VD) (reference), assisted VD, planned CS and emergency CS) and mode of delivery by induction of labour status. Crude and adjusted binary logistic regression and linear regression models were fitted examining BMI and BF% at age 17 years respectively, adjusting for several potential confounders. RESULTS Adolescents born by CS did not have an elevated BMI or BF% compared to those born by normal VD. The fully adjusted results for overweight and obesity in children born by planned CS, compared to VD, were 1.05 (95% CI: 0.86-1.28) and 0.94 (95% CI: 0.72-1.23), respectively. The results were similar for the associations between CS and BF%, and between induction of labour and BMI. CONCLUSION Overall, this large longitudinal study did not support an association between CS or induction of labour and overweight, obesity or BF%. It is possible that previously reported associations are due to residual or unmeasured confounding and/or underlying indications for CS delivery.

Pre-pregnancy body mass index and caesarean section in Andean women in Peru: a prospective cohort study. BMC Pregnancy Childbirth 2024; 24:304. [PMID: 38654289 DOI: 10.1186/s12884-024-06466-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 03/29/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND During the last two decades, Caesarean section rates (C-sections), overweight and obesity rates increased in rural Peru. We examined the association between pre-pregnancy body mass index (BMI) and C-section in the province of San Marcos, Northern Andes-Peru. METHODS This is a prospective cohort study. Participants were women receiving antenatal care in public health establishments from February 2020 to January 2022, who were recruited and interviewed during pregnancy or shortly after childbirth. They answered a questionnaire, underwent a physical examination and gave access to their antenatal care card information. BMI was calculated using maternal height, measured by the study team and self-reported pre-pregnancy weight measured at the first antenatal care visit. For 348/965 (36%) women, weight information was completed using self-reported data collected during the cohort baseline. Information about birth was obtained from the health centre's pregnancy surveillance system. Regression models were used to assess associations between C-section and BMI. Covariates that changed BMI estimates by at least 5% were included in the multivariable model. RESULTS This study found that 121/965 (12.5%) women gave birth by C-section. Out of 495 women with pre-pregnancy normal weight, 46 (9.3%) had C-sections. Among the 335 women with pre-pregnancy overweight, 53 (15.5%) underwent C-sections, while 23 (18.5%) of the 124 with pre-pregnancy obesity had C-sections. After adjusting for age, parity, altitude, food and participation in a cash transfer programme pre-pregnancy overweight and obesity increased the odds of C-section by more than 80% (aOR 1.82; 95% CI 1.16-2.87 and aOR 1.85; 95% CI 1.02-3.38) compared to women with a normal BMI. CONCLUSIONS High pre-pregnancy BMI is associated with an increased odds of having a C-section. Furthermore, our results suggest that high BMI is a major risk factor for C-section in this population. The effect of obesity on C-section was partially mediated by the development of preeclampsia, suggesting that C-sections are being performed due to medical reasons.

Kenkel WM, Ahmed S, Partie M, Rogers K. Delivery by cesarean section leads to heavier adult bodyweight in prairie voles (Microtus ochrogaster). Horm Behav 2024; 160:105499. [PMID: 38350334 PMCID: PMC10961198 DOI: 10.1016/j.yhbeh.2024.105499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 11/20/2023] [Accepted: 01/29/2024] [Indexed: 02/15/2024]
Abstract
Delivery by cesarean section now makes up 32.1 % of all births in the United States. Meta-analyses have estimated that delivery by cesarean section is associated with a > 50 % increased risk for childhood obesity by 5 years of age. While this association is independent of maternal obesity, breastfeeding, and heritable factors, studies in humans have been unable to test for a causal role of cesarean delivery in this regard. Here, we set out to use an animal model to experimentally test whether delivery by cesarean section would increase offspring weight in adulthood. Delivery by cesarean section may exert neurodevelopmental consequences by impacting hormones that are important at birth as well as during metabolic regulation in later life, such as oxytocin and vasopressin. The prairie vole (Microtus ochrogaster) has long been studied to investigate the roles of oxytocin and vasopressin in brain development and social behavior. Here, we establish that prairie voles tolerate a range of ambient temperatures, including conventional 22° housing, which makes them translationally appropriate for studies of diet-induced obesity. We also studied vole offspring for their growth, sucrose preference, home cage locomotor activity, and food consumption after birth by either cesarean section or vaginal delivery. At sacrifice, we collected measures of weight, length, and adipose tissue to analyze body composition in adulthood. Voles delivered by cesarean section had consistently greater bodyweights than those born vaginally, despite having lower food consumption and greater locomotive activity. Cesarean-delivered animals were also longer, though this did not explain their greater body weights. While cesarean delivery had no effect on vasopressin, it resulted in less oxytocin immunoreactivity within the hypothalamus in adulthood. These results support the case that cesarean section delivery plays a causal role in increasing offspring body weight, potentially by affecting the oxytocin system.

Chu J, Keedle H, Sutcliffe K, Blumenthal N, Levett K. The outcomes for women planning a VBAC at a private hospital in Australia. Birth 2024. [PMID: 38212947 DOI: 10.1111/birt.12811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 10/27/2023] [Accepted: 12/20/2023] [Indexed: 01/13/2024]
Abstract
BACKGROUND Rates of cesarean birth (CBs) are steadily increasing and account for 36.7% of all births in New South Wales (NSW), with primary cesareans driving the increase. NSW Health guidelines recommend women attempt a vaginal birth after a previous CB (VBAC); however, rates of VBAC are decreasing, particularly within the private hospital setting. This study aimed to determine the rates of adverse outcomes for women who planned a VBAC (pVBAC) compared with women who planned an elective repeat CB (pERCB) at one private hospital in Sydney, Australia. METHOD This retrospective data review evaluated patient records over a 10-year period (2010-2019). Records (n = 2039) were divided into four groups: pVBAC, pVBAC + EMCB, labor + ERCB (lab + ERCB), and pERCB. The incidence of adverse maternal and neonatal outcomes is reported as counts and percentages. Regression and chi-squared tests were used to compare groups. Significance was determined at a p-value of <0.05. RESULTS Overall, very low rates (N = 148, 7.3%) of women had a VBAC compared with a repeat CB at this private hospital over the 10-year period. The incidence of adverse outcomes was low regardless of study group. Outcomes differed significantly between groups for postpartum hemorrhage (pERCB seven times less likely than VBAC group) and special care nursery admission (pVBAC + EMCB is 4.6 times more likely than in the VBAC group). CONCLUSION Overall, it is safe to attempt a VBAC at this private hospital, and labor after a cesarean should be recommended, yet very few women had a VBAC at the study site. The incidence of adverse outcomes was low compared with other published research.

Abstract
To examine whether the prevailing hypothesis of an association between caesarean section (CS) delivery method and increased weight status in early childhood is observed in Japanese. A total of 1277 mother-infant pairs from a prospective hospital-based mother-infant birth cohort that recruited women in their first trimester from May 2010 to November 2013 were included. We assessed the relationship between delivery method and weight status of delivered children at 1, 3 and 6 years of age. In total, 366 children (28.7%) were delivered by CS. Delivery by CS was not associated with body mass index (BMI) z-score (≥ 75 percentile) at age 1 year, (odds ratio (OR) 0.97, 95% confidence interval (CI) 0.69-1.36), 3 years (OR 0.98, 95% CI 0.67-1.42), and 6 years (OR 0.71, 95% CI 0.45-1.12), and also showed no association with low weight status (< 25th percentile). Supplemental evaluations addressing the influence of preterm births, pre-pregnancy BMI, emergency CS, and modification by breastfeeding were consistent with the primary analyses. Our findings do not support the hypothesis that children born by CS are at risk of being overweight in childhood among the Japanese population.

Abstract
The cardiovascular disease is the main cause of worldwide death. This profile is potentialized by the increased severity of infections in people with obesity, type 2 diabetes and hypertension. Children and adolescents are target groups for the prevention of non-communicable diseases. The Developmental Origins of Health and Disease concept points that perinatal conditions are an important risk factor to development of non-communicable disease in adulthood. In this context, the present review identifies perinatal factor that induces precocious cardiovascular risk factors, related with cardiometabolic syndrome. The low or high birth weight and caesarean delivery are risk factors that induce increased occurrence of cardiovascular risk biomarkers in children and adolescents, while the breast feeding or feeding with breast milk from the birth until two years-old is a protector strategy. Evaluation of perinatal conditions associated with precocious identification of cardiovascular risk factors in children and adolescents is an efficient strategy to prevent and control cardiovascular mortality; through interventions, as lifestyle changes during vulnerable windows of development, able to set up the risk to cardiometabolic disease.

Abstract
PROBLEM Previous studies document an association between mode of delivery (MOD) and allergic conditions in children. Immunoglobulin (Ig) concentrations at birth may play a role. The goal of this study is to assess the impact of MOD on Ig concentrations at delivery from newborn dried blood spots (DBS). METHOD OF STUDY The Upstate KIDS Study (2008-2010) is a prospective cohort of mother-child pairs recruited from New York State, excluding New York City. Ig subtypes IgA, IgE, IgG1 , IgG2 , IgG3 , IgG4 , and IgM were measured in residual NDBS from the Newborn Screening Program (N = 3274 infants). MOD was categorized as vaginal delivery (VD), emergency cesarean delivery (ECD) or planned cesarean delivery (PCD). Associations between MOD and Ig levels were assessed using ANOVA and multiple regression, with models adjusted for gestational age, birth weight, maternal race, plurality, and smoking status. RESULTS IgA, and the IgG subtypes IgG3 and IgG4 were found to be significantly lower in PCD neonates relative to VD neonates in adjusted regression models: 3.57 mg/ml, (95% CI: 3.51, 3.63) compared to 3.64 mg/ml (95% CI: 3.59, 3.69); 8.95 ng/ml (95% CI: 8.88,9.03) compared to 9.03 ng/ml (95% CI: 8.98, 9.08) and 8.05 ng/ml (95% CI: 7.91, 8.20) compared to 8.22 ng/ml (95% CI: 7.91,8.20), respectively. CONCLUSIONS MOD may thus be related to neonatal immune profile. Results were found to be robust to sensitivity testing based on maternal complications and indication for CD. Clinical implications are unclear given the small levels of association found in newborns, but the result suggests greater susceptibility to infection, and further study is warranted.

Abstract
Cesarean delivery is associated with diminished plasma levels of several 'birth-signaling' hormones, such as oxytocin and vasopressin. These same hormones have been previously shown to exert organizational effects when acting in early life. For example, our previous work found a broadly gregarious phenotype in prairie voles exposed to oxytocin at birth. Meanwhile, cesarean delivery has been previously associated with changes in social behavior and metabolic processes related to oxytocin and vasopressin. In the present study, we investigated the long-term neurodevelopmental consequences of cesarean delivery in prairie voles. After cross-fostering, vole pups delivered either via cesarean or vaginal delivery were studied throughout development. Cesarean-delivered pups responded to isolation differently in terms of their vocalizations (albeit in opposite directions in the two experiments), huddled in less cohesive groups under warmed conditions, and shed less heat. As young adults, we observed no differences in anxiety-like or alloparental behavior. However, in adulthood, cesarean-delivered voles of both sexes failed to form partner preferences with opposite sex conspecifics. In a follow-up study, we replicated this deficit in partner-preference formation among cesarean-delivered voles and were able to normalize pair-bonding behavior by treating cesarean-delivered vole pups with oxytocin (0.25 mg/kg) at delivery. Finally, we detected minor differences in regional oxytocin receptor expression within the brains of cesarean-delivered voles, as well as microbial composition of the gut. Gene expression changes in the gut epithelium indicated that cesarean-delivered male voles have altered gut development. These results speak to the possibility of unintended developmental consequences of cesarean delivery, which currently accounts for 32.9 % of deliveries in the U.S. and suggest that further research should be directed at whether hormone replacement at delivery influences behavioral outcomes in later life.

Abstract
BackgroundOptimal early infant feeding practices are critical to ensure adequate nutrition for infants’ growth and development. This study aimed to examine the determinants of suboptimal early feeding practices (i.e., delayed initiation of breastfeeding, prelacteal feeding, and non-exclusive breastfeeding) among infants aged 0–5 months in Indonesia.MethodsWe used data collected in the 2012 and 2017 Indonesia Demographic and Health Surveys. Analyses were conducted using information from 3,198 live-born singleton infants aged 0–5 months. The primary outcomes used were: (1) delayed initiation of breastfeeding in the first hour after birth, (2) prelacteal feeding in the first 3 days, and (3) non-exclusive breastfeeding in the last 24 h preceding the survey. Potential predictors analyzed were categorized into the environmental, household, maternal, pregnancy, delivery, and child characteristics. Logistic regression analyses were performed to identify factors significantly associated with each outcome.ResultsApproximately 78,6% of infants aged 0–5 months in Indonesia had at least one of the three suboptimal early infant feeding practices. We found a strong association between the three outcome indicators analyzed. The determinants of delayed initiation of breastfeeding included infants from Sumatera region (adjusted odds ratios (aOR) = 2.02, p < 0.001), infants delivered by Cesarean section (aOR = 2.78, p < 0.001), and in non-health facilities (aOR = 1.53, p = 0.003). The determinants of prelacteal feeding in the first 3 days included infants living in urban areas (aOR = 1.32, p = 0.035), the first birth-ranked infants (aOR = 1.32, p = 0.019), and infants who had delayed initiation of breastfeeding in the first hour of life (aOR = 3.90, p < 0.001). The determinants of non-exclusive breastfeeding in the last 24 h included infants whose mothers worked in non-agricultural fields (aOR = 1.52, p < 0.001), infants delivered by Cesarean section (aOR = 1.33, p = 0.044), and the first birth-ranked infants (aOR = 1.28, p = 0.039).ConclusionThere was a high percentage of infants aged 0–5 months who had suboptimal feeding practices in Indonesia. As we found multiple factors associated with suboptimal early feeding practices among infants, integrated approaches, including health promotion and supportive public policy, are required to ensure infants receive adequate nutrition in the early stages of life.

The Relationship between Psychological Suffering, Value of Maternal Cortisol during Third Trimester of Pregnancy and Breastfeeding Initiation. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020339. [PMID: 36837540 PMCID: PMC9960982 DOI: 10.3390/medicina59020339] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/07/2023] [Accepted: 02/09/2023] [Indexed: 02/15/2023]
Abstract
Background and Objectives: Cortisol, the stress hormone, is an important factor in initiating and maintaining lactation. Maternal suffering during pregnancy is predictive for the initiation and shorter duration of breastfeeding and can also lead to its termination. The aim of this study is to evaluate the relationship between the level of salivary cortisol in the third trimester of pregnancy and the initiation of breastfeeding in the postpartum period in a cohort of young pregnant women who wanted to exclusively breastfeed their newborns during hospitalization. Materials and Methods: For the study, full-term pregnant women were recruited between January and May 2022 in the Obstetrics and Gynecology Clinic of the Mureș County Clinical Hospital. Socio-demographic, clinical obstetric and neonatal variables were collected. Breastfeeding efficiency was assessed using the LATCH Breastfeeding Assessment Tool at 24 and 48 h after birth. The mean value of the LATCH score assessed at 24 and 48 h of age was higher among mothers who had a higher mean value of salivary cortisol measured in the third trimester of pregnancy (p < 0.05). A multivariate logistic regression model was used to detect risk factors for the success of early breastfeeding initiation. Results: A quarter of pregnant women had a salivary cortisol level above normal limits during the third trimester of pregnancy. There is a statistically significant association between maternal smoking, alcohol consumption during pregnancy and the level of anxiety or depression. Conclusions: The most important finding of this study was that increased salivary cortisol in the last trimester of pregnancy was not associated with delayed initiation/absence of breastfeeding.

Abstract
OBJECTIVE To explore the trends, determinants, and short-term maternal and neonatal health outcomes of Caesarean section on maternal request (CSMR). DESIGN Population-based record linkage study. SETTING Birth registry data for all births in Queensland, Australia, from 2008 to 2017. PARTICIPANTS Pregnancies resulting in live or intrapartum stillbirth with >=20 gestational weeks and/or >=400 gm birth weight were the study population. The analytic sample was restricted to low-risk pregnancies by excluding preterm, non-cephalic pregnancies with medical risk factors. MEASUREMENTS CSMR was defined as a first-time C-section in singleton, term pregnancies with an ICD-10-AM code of O-82/O-47. CSMR trend was reported in age-standardised rate using a join-point regression model. The determinants and perinatal outcomes of CSMR were tested against Spontaneous vaginal births (VBs) and planned VBs including assisted VBs and emergency C-sections in this group. The generalised estimating equation technique was used for regression analysis and reported in the odds ratio (OR) at a 95% Confidence Interval (CI). FINDINGS Of total C-sections (n = 204,863), the average annual change in CSMR rate was 4.4% (95% CI: 2.1-6.7%, p<0.01) for the total pregnancies (N=613,375) Of the analytic sample (N=365568), nulliparous women with age ≥35 years (OR: 2.32,95% CI: 2.09-2.57), delivered at private hospitals (OR:4.90; 95% CI: 4.65-5.18); with mood disorders (OR: 2.15; 95% CI: 1.88-2.43) were positive and midwives birth attendant (OR 0.28; 95% CI: 0.26 to 0.30) was negative influencing factors for CSMR. In a propensity score matched sample; CSMR observed an increasedrisk of anaesthetic complications (OR: 8.00; 95% CI:1.95-32.82) and slightly reduced odds of birth asphyxia (OR:0.20;95%CI:0.06-0.60)against planned VBs while the overall incidence of birth-asphyxia was low (1.29%) However, neonatal morbidities (OR:1.61; 95% CI:1-2.59) and special care admission (OR:2.15; 95% CI:1.03-4.5) were higher after CSMR in comparison to SVBs CONCLUSION: Despite being linked with adverse perinatal health outcomes, the incidence of CSMR increased 1.75-fold during the past 10 years. Maternal educational interventions to provide adequate information, including the long-term risks and benefits of C-sections, can help reduce the growing rates of CSMR.

Planned mode of birth after previous cesarean section: A structured review of the evidence on the associated outcomes for women and their children in high-income setting. Front Med (Lausanne) 2022; 9:920647. [PMID: 36148449 PMCID: PMC9486480 DOI: 10.3389/fmed.2022.920647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 08/08/2022] [Indexed: 12/05/2022] Open
Abstract
In many high-income settings policy consensus supports giving pregnant women who have had a previous cesarean section a choice between planning an elective repeat cesarean section (ERCS) or planning a vaginal birth after previous cesarean (VBAC), provided they have no contraindications to VBAC. To help women make an informed decision regarding this choice, clinical guidelines advise women should be counseled on the associated risks and benefits. The most recent and comprehensive review of the associated risks and benefits of planned VBAC compared to ERCS in high-income settings was published in 2010 by the US Agency for Healthcare Research and Quality (AHRQ). This paper describes a structured review of the evidence in high-income settings that has been published since the AHRQ review and the literature in high-income settings that has been published since 1980 on outcomes not included in the AHRQ review. Three databases (MEDLINE, EMBASE, and PsycINFO) were searched for relevant studies meeting pre-specified eligible criteria, supplemented by searching of reference lists. Forty-seven studies were identified as meeting the eligibility criteria and included in the structured review. The review suggests that while planned VBAC compared to ERCS is associated with an increased risk of various serious birth-related complications for both the mother and her baby, the absolute risk of these complications is small for either birth approach. The review also found some evidence that planned VBAC compared to ERCS is associated with benefits such as a shorter length of hospital stay and a higher likelihood of breastfeeding. The limited evidence available also suggests that planned mode of birth after previous cesarean section is not associated with the child’s subsequent risk of experiencing adverse neurodevelopmental or health problems in childhood. This information can be used to manage and counsel women with previous cesarean section about their subsequent birth choices. Collectively, the evidence supports existing consensus that there are risks and benefits associated with both planned VBAC and ERCS, and therefore women without contraindications to VBAC should be given an informed choice about planned mode of birth after previous cesarean section. However, further studies into the longer-term effects of planned mode of birth after previous cesarean section are needed along with more research to address the other key limitations and gaps that have been highlighted with the existing evidence.

Abstract
This study aimed to examine the association of cesarean delivery with trajectories of growth and body composition in preschool children. This ambidirectional cohort study was conducted between 2017 and 2020 in China. Information on the delivery mode, weight, and length/height of the children measured at routine healthcare visits was obtained from maternal and child health records. For three years while in kindergarten, children’s body mass index (BMI), fat mass index (FMI), fat-free mass index (FFMI), and percentage of body fat (FM%) were repeatedly measured. A BMI z score (zBMI) was calculated and standardized to WHO measures, and overweight and obesity were defined using the WHO reference. After adjustment for maternal age, maternal education, annual family income, prepregnancy BMI, gestational weight gain, gravidity, parity, gestational age, child sex, birthweight, breastfeeding duration, and the parent-reported dietary intake of the children, children born via cesarean delivery (n = 1992) versus those born vaginally (n = 1578) had higher zBMI growth rates beyond 36 months (β: 0.003; 95% CI: 0.001, 0.005 SD units/month) and elevated levels of FMI (β: 0.097; 95% CI: 0.026, 0.168 kg/m2), FM% (β: 0.402; 95% CI: 0.058, 0.745%) and zBMI (β: 0.073; 95% CI: 0.012, 0.133 units), but not FFMI (β: 0.022; 95% CI: −0.022, 0.066 kg/m2). The adjusted OR of overweight and obesity was 1.21 (95% CI: 1.04, 1.40). Cesarean delivery likely elevated zBMI growth rates and increased the risk of overweight and obesity in preschool children, with the elevation of fat mass but not fat-free mass.

Abstract
Obesity is considered a global public health problem. Cesarean section has been associated with high body mass index (BMI) and increased obesity throughout life. However, this association has been challenged by some studies. This study aims to assess the causal effect of cesarean section on the BMI of children aged 1-3 years. This is a cohort study of 2,181 children aged 1-3 years, born in 2010, obtained from the BRISA Birth Cohort, in São Luís, state of Maranhão, Brazil. Sociodemographic variables, maternal characteristics, type of childbirth, morbidity, anthropometric measurements, and BMI were assessed. Marginal structural models with a counterfactual approach were used to check the causal effect of the type of childbirth on obesity, weighted by the inverse probability of selection and exposure. Out of the 2,181 children assessed (52% female), 50.6% were born by cesarean section, 5.9% of the newborn infants were large for gestational age, and 10.7% of them had excess weight. No causal effect of cesarean section on BMI was observed (coefficient = -0.004; 95%CI: -0.136; 0.127; p = 0.948). Cesarean section did not have a causal effect on the BMI of children aged 1-3 years.

Abstract
INTRODUCTION The purpose of this study was to increase understanding of the components of the US birth center model of prenatal care and how the birth center prenatal care model contributes to birthing people's confidence for physiologic childbirth. METHODS This was a qualitative descriptive study using semistructured interviews with individuals who gave birth in freestanding birth centers. Birthing people were recruited from freestanding birth centers in a Midwestern US state and were between the ages of 18 and 42, were English-speaking, and had experienced a birth center birth within the previous 6 months. Interviews were transcribed and analyzed using Glaser's constant comparative method. RESULTS Twelve women who gave birth in birth centers, representing urban and rural settings, participated. Four core categories were identified encompassing the components of birth center prenatal care and how the birth center model contributes to women's confidence for physiologic birth: birth center culture and processes, midwifery model of care within the birth center, internal influences, and outside influences. DISCUSSION Women who gave birth in birth centers believed that the birth center culture and environment, the midwifery model of care in the birth center, internal influences including the belief that birth is a normal physiologic process, and outside influences including family support and positive birth stories contributed to their confidence for physiologic birth.

Abstract
There has been a significant increase in Caesarean section (C-section) births worldwide over the past two decades and although it is can be a life-saving procedure, the enduring effects on host physiology are now undergoing further scrutiny. Indeed, epidemiological data have linked C-section birth with multiple immune, metabolic and neuropsychiatric diseases. Birth by C-section is known to alter the colonisation of the neonatal gut microbiota (with C-section delivered infants lacking vaginal microbiota associated with passing along the birth canal), which in turn can impact the development and maintenance of many important biological systems. Appropriate animal models are key to disentangling the role of missing microbes in brain health and disease in C-section births. In this review of preclinical studies, we interrogate the effects of C-section birth on the development (and maintenance) of several biological systems and we discuss the involvement of the gut microbiome on C-section-related alterations.

Abstract
As compared with vaginal delivery (VD), caesarean section (CS) birth could be associated with increased risk of obesity in young adult offspring. We aimed to evaluate this association by updating data from a systematic review with meta-analysis of observational studies. From 3774 records identified in PubMed and Embase, we retained six studies and added five studies from the last systematic review, for a total of 11 studies. Crude estimates of the association were retrieved from nine cohort studies (n = 143,869), and maximally adjusted estimates were retrieved from eight cohort studies. Young adults born by CS had higher risk of obesity (body mass index [BMI] ≥ 30 kg/m2 ) than young adults born by VD, corresponding to a crude pooled risk ratio (RR) of 1.30 [95% confidence interval (CI) 1.13 to 1.50] and a maximally adjusted pooled RR of 1.22 [95% CI 1.02 to 1.46]. In a sensitivity analysis pooling, five studies that included maternal prepregnancy BMI, a major potential confounding factor, in the set of controlled covariates, the RR was 1.08 [95% CI 0.92 to 1.27]. We concluded that the association between CS and obesity in young adulthood was mostly explained by confounding from maternal prepregnancy BMI.

Abstract
Background and Objective: Colostrum feeding is known for its immune benefits for reduction in nosocomial sepsis, necrotizing enterocolitis, and ventilator-associated pneumonias. Colostrum feeding also helps in improving breastfeeding rates and early discharge of vulnerable neonatal intensive care unit (NICU) babies. The objective of this study was to improve early colostrum feeding/oropharyngeal colostrum administration in a busy tertiary NICU in India. Methods: Multiple plan-do-study-act (PDSA) cycles were conducted from January 2020 to September 2020 to improve early colostrum feeding rates in NICU babies to >60%. We tested change ideas such as training of health care personnel, counseling of mothers and families about importance of colostrum expression and feeding, bedside collection of colostrum, safe transportation of colostrum to the NICU, and electronic data handling. Sustainability of the interventions was studied from October 2020 to March 2021 and data were analyzed. Results: Early colostrum feeding rates improved from a baseline of 4.36-68.21% after six PDSA cycles through 9 months. After counseling of mothers and families of NICU babies, rates of breastfeeding and colostrum feeding improved to 98.8% and 97.11%, respectively. The early breast stimulation and colostrum expression rates also improved to 87.28% and 68.2%, respectively. Early colostrum feeding rate was 87.5% after 6 months through the sustainability phase. Conclusions: Quality improvement interventions significantly improved the rate of early colostrum feeding in sick babies admitted to a busy NICU, and the improvement was sustained for 6 months.

Abstract
This study aimed to examine fear of childbirth (FOC) before and after delivery in relation to personality (anxiety and anxiety sensitivity) and birth experience (type of delivery, pain, and staff support). One-hundred and five women completed questionnaires during pregnancy and one month after childbirth. Participants completed the Wijma Delivery Expectancy/Experience Questionnaire; the State and Trait Anxiety Inventory and Anxiety Sensitivity Index, and the McGill Pain Questionnaire and a Support from staff questionnaire. FOC levels decreased after childbirth, but only in the high-level fear group. Path analysis showed that physical concerns, one aspect of anxiety sensitivity, shape FOC during pregnancy. Together with interventions at delivery (instrumental vaginal delivery and emergency caesarean section), pain and low staff support, this in turn modifies FOC after delivery. In conclusion, FOC decreases after childbirth. However, combined with adverse birth experience and certain personality traits, FOC during pregnancy affects FOC after delivery.

Abstract
BACKGROUND The etiology of non-Hodgkin lymphoma (NHL) in children and in adolescents and young adults (AYA) is not well understood. METHODS We evaluated potential associations between mode of delivery, birth characteristics, and NHL risk in a population-based case-control study, which included 3,064 cases of NHL [490 with Burkitt lymphoma, 981 with diffuse large B-cell lymphoma (DLBCL), and 978 with T-cell NHL) diagnosed at the age of 0 to 37 years in California during 1988 to 2015 and 153,200 controls frequency matched on year of birth. Odds ratios (OR) and 95% confidence intervals (CI) were estimated from an unconditional multivariable logistic regression model that included year of birth and birth characteristics. RESULTS Individuals born via cesarean section had a decreased risk of pediatric Burkitt lymphoma (age 0-14 years; OR = 0.71, 95% CI: 0.51-0.99) and pediatric T-cell NHL (OR = 0.73, 95% CI: 0.55-0.97) compared with those born vaginally. Having a birth order of second (OR = 0.73, 95% CI: 0.57-0.93) or third or higher (OR = 0.76, 95% CI: 0.58-0.99) was associated with a lower risk of pediatric T-cell NHL compared with first-borns. AYA (age 15-37 years) with a heavier birthweight had an elevated risk of DLBCL (OR for each kg = 1.16, 95% CI: 1.00-1.35). Associations between other birth characteristics, including plurality, maternal age, maternal education, and NHL risk, also exhibited variations across subgroups based on age of diagnosis and histologic subtype. CONCLUSIONS These findings support a role of mode of delivery and birth characteristics in the etiology of early-onset NHL. IMPACT This study underscores the etiologic heterogeneity of early-onset NHL.

Caesarean section and its relationship to offspring general cognitive ability: a registry-based cohort study of half a million young male adults. EVIDENCE-BASED MENTAL HEALTH 2021; 25:7-14. [PMID: 34511405 PMCID: PMC8788259 DOI: 10.1136/ebmental-2021-300307] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 08/28/2021] [Indexed: 11/25/2022]
Abstract
Background A relationship between caesarean section and offspring cognitive ability has been described, but data are limited, and a large-scale study is needed. Objective To determine the relationship between mode of delivery and general cognitive ability. Methods A cohort of 579 244 singleton males, born between 1973 and 1987 who conscripted before 2006, were identified using the Swedish population-based registries. Their mode of delivery was obtained from the Swedish Medical Birth registry. The outcome measure was a normalised general cognitive test battery (mean 100, SD 15) performed at military conscription at around age 18. Findings Males born by caesarean section performed poorer compared with those born vaginally (mean score 99.3 vs 100.1; adjusted mean difference −0.84; 95% CI −0.97 to −0.72; p<0.001). Both those born by elective (99.3 vs 100.2; −0.92; 95% CI −1.24 to −0.60; p<0.001) and non-elective caesarean section (99.2 vs 100.2; −1.03; 95% CI −1.34 to −0.72; p=0.001), performed poorer than those born vaginally. In sibling analyses, the association was attenuated to the null (100.9 vs 100.8; 0.07; 95% CI −0.31 to 0.45; p=0.712). Similarly, neither elective nor non-elective caesarean section were associated with general cognitive ability in sibling analyses. Conclusion Birth by caesarean section is weakly associated with a lower general cognitive ability in young adult males. However, the magnitude of this association is not clinically relevant and seems to be largely explained by familial factors shared between siblings. Clinical implication Clinicians and gravidas ought not to be concerned that the choice of mode of delivery will impact offspring cognitive ability.

Does Timing of Antenatal Care Initiation and the Contents of Care Have Effect on Caesarean Delivery in Ethiopia? Findings from Demographic and Health Survey. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2021; 2021:7756185. [PMID: 34422065 PMCID: PMC8371644 DOI: 10.1155/2021/7756185] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 08/03/2021] [Indexed: 11/18/2022]
Abstract
Background Antenatal care (ANC) is an important preventive set of core healthcare services through pregnancy. Caesarean deliveries are significantly increasing in many low-, middle-, and high-income countries. However, overuse of the caesarean section service interferes with the quality and cost of the procedure. Hence, this study aimed to assess the effect of timing of first antenatal care initiation and the contents of care on caesarean delivery. Methods A population level cross-sectional study was conducted with a total of 4757 study participants. The multivariable analysis was computed using the setup of 3 models. Results The rate of caesarean section among women who initiated antenatal care in the first trimester was 1.32% (95% CI = 0.91–4.21). Women initiated antenatal care in the first trimester (AOR = 2.74; 95% CI = 1.49–6.2) and received contents of care (AOR = 1.98; 95% CI = 1.24–3.78])were more likely to have caesarean section delivery as compared to their counterparts. Conclusion Caesarean section among women who initiated ANC in the first trimester is low. The finding suggests ANC initiated early (within 16 weeks) can have a positive impact on caesarean section delivery. In addition, being urban residents, primipara women, initiating antenatal care before 16 weeks, received contents of care, and having antenatal care visits three and more increase the odds of having caesarean section. As a result, different obstetric, medical, and surgical complications are detected and managed as early as possible.

Abstract
BACKGROUND Caesarean section (CS) is associated with an increased risk of adverse health outcomes for both mothers and offspring. The evidence for an association between CS and reduced offspring cognitive and academic performance has been inconsistent, with considerable limitations. AIM The aim of this study is to compare cognitive and academic performance in childhood and early adulthood in offspring delivered by CS with those delivered vaginally at term. MATERIALS AND METHODS Data on 4327 mothers and offspring from a longitudinal birth cohort study were analysed. Offspring cognitive performance was measured by the Picture Peabody Vocabulary Test-Revised (PPVT-R) at ages five and 21 and the Raven's Standard Progressive Matrices at age 14. Academic achievement was assessed using the Wide Range Achievement Test at age 14. RESULTS After adjustment for confounding factors, there was no statistically significant association between cognitive performance and offspring birth mode at age five (P = 0.11). The adjusted difference of mean scores at five years on the PPVT-R for elective CS birth compared to those born by vaginal delivery was -2.2 (95% confidence interval (CI) -4.3 to -0.2), whereas for emergency CS it was 0.0 (95% CI -2.0 to 2.0). There were no differences in cognitive or academic performance at ages 14 and 21. CONCLUSION Birth mode was not significantly associated with offspring cognitive or academic performance. Our study does not support concerns that CS is associated with a reduction in cognitive performance.

Associations of caesarean section with body mass and waist circumference trajectories from age 2 to 13 years: A nationally representative birth cohort study in Australia.

Abstract
BACKGROUND Measuring obesity at a single time point does not explain the independent association between C-section birth and obesity in a child's life course. OBJECTIVES This study aimed to explore the longitudinal link between C-section with obesity trajectories during childhood. METHODS We analysed data from a nationally representative birth cohort study named "Longitudinal Study of Australian Children (LSAC)", commenced in 2004. General obesity was measured through the Body Mass Index (BMI) and abdominal obesity by the Waist Circumference (WC) using the biennially collected data from age 2 to 13 years (2006-2016). Group-based trajectory modelling was applied to identify the distinct pattern of BMI & WC trajectories. Multivariable multinomial logistic regression models were used to assess the association between C-section and obesity trajectories after adjusting for perinatal factors. RESULTS Of the 3524 study children, 30% were born by C-section. Three distinct BMI trajectory groups emerged: stable normal (60%), moderately rising (33%) and accelerated (7%). The WC trajectories were, stable normal (58%), moderate (34%) and accelerated (8%). Compared with the stable normal group, children born through C-section had a higher risk to follow accelerated trajectories for both BMI (OR:1.72; 95% CI: 1.28-2.32) and WC (OR: 1.51; 95% CI: 1.15-1.98) with P-value <0.01. Adjustment of potential confounders did not alter these associations substantially. CONCLUSIONS C-section birth significantly increases the risk of having an accelerated obesity trajectory in children. Limiting the C-section for absolute clinical causes and early institution of preventive approach can reduce the obesity burden among children delivered through C-section.

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

Abstract
Fee equalization in health care brings under a unique tariff several medical treatments, coded under different Diagnosis Related Groups (DRGs). The aim is to improve healthcare quality and efficiency by discouraging unnecessary, but better-paid, treatments. We evaluate its effectiveness on childbirth procedures to reduce overuse of c-sections by equalizing the DRGs for vaginal and cesarean deliveries. Using data from Italy and a difference-in-differences approach, we show that setting an equal fee decreased c-sections by 2.6%. This improved the appropriateness of medical decisions, with more low-risk mothers delivering naturally and no significant changes in the incidence of complications for vaginal deliveries. Our analysis supports the effectiveness of fee equalization in avoiding c-sections, but highlights the marginal role of financial incentives in driving c-section overuse. The observed drop was only temporary and in about a year the use of c-sections went back to the initial level. We found a greater reduction in lower quality, more capacity-constrained hospitals. Moreover, the effect is driven by districts where the availability of Ob-Gyn specialists is higher and where women are predominant in the gender composition of Ob-Gyn specialists.

Abstract
OBJECTIVE This study analysed the association between caesarean section and early childhood caries (ECC), estimating the effects using regression and causal inference models. METHODS This was a historical cohort study of 697 mother-child dyads, conducted in São Luís, Brazil. The caesarean section was the exposure, and the severity of ECC (dmft) was the outcome. Covariates household income, maternal schooling, maternal hypertension, maternal obesity and birth weight were adjusted for in the models. The effects were estimated by Poisson regression (Means Ratio-MR) and causal inference using a marginal structural model (MSM) (MR and Average Treatment Effect-ATE coefficients), weighted by the inverse probability (IPW) of exposure. RESULTS Caesarean section was protective against caries in the bivariate (MR 0.81; CI 0.70-0.94; P = 0.005) and multivariate (MR 0.78; CI 0.67-0.91; P = 0.002) models. In MSM analyses, the caesarean section had no effect on ECC (ATE = -0.35; P = 0.107), controlling for IPW of exposure. CONCLUSION The apparent association between caesarean section and ECC severity seems spurious, as it did not persist after employing a superior approach to estimating causality.

Abstract
PURPOSE Studies have reported children born by caesarean section are more likely to have lower cognitive outcomes compared to those born by vaginal delivery. This paper reviews the literature examining caesarean birth and offspring cognitive outcomes. METHODS A systematic search for observational studies or case-control studies that compared cognitive outcomes of people born by caesarean section with those born by vaginal delivery was conducted in six databases (Medline, PubMed, EMBASE, PsychInfo, CINAHL, Web of Science) from inception until December 2019 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were assessed for quality and a narrative synthesis was undertaken considering the evidence for a causal relationship according to the Bradford Hill Criteria. RESULTS A total of seven studies were identified. Of these, four found a significant association between elective and emergency caesarean birth and reduction in offspring cognitive performance as measured by school performance or validated cognitive testing. Three studies found no association. There was variability in the quality of the studies, assessment of the reason for caesarean section (emergency vs elective), measurement of outcomes and adjustment for confounding factors. CONCLUSION The evidence of an association between CS birth and lower offspring cognitive functioning is inconsistent. Based on currently available data, there is no evidence that a causal association exists. To better examine this association, future studies should (a) distinguish elective and emergency caesareans, (b) adequately adjust for confounding variables and (c) have valid outcome measures of cognition.

Abstract
Acquisition and establishment of the oral microbiota occur in a dynamic process over various stages and involve close and continuous interactions with the host and its environment. In the present review, we discuss the stages of this process in chronological order. We start with the prenatal period and address the following questions: ‘Is the fetus exposed to maternal microbiota during pregnancy?’ and ‘If so, what is the potential role of this exposure?’ We comment on recent reports of finding bacterial DNA in placenta during pregnancies, and provide current views on the potential functions of prenatal microbial encounters. Next, we discuss the physiological adaptations that take place in the newborn during the birth process and the effect of this phase of life on the acquisition of the oral microbiota. Is it really just exposure to maternal vaginal microbes that results in the difference between vaginally and Cesarian section‐born infants? Then, we review the postnatal phase, in which we focus on transmission of microbes, the intraoral niche specificity, the effects of the host behavior and environment, as well as the role of genetic background of the host on shaping the oral microbial ecosystem. We discuss the changes in oral microbiota during the transition from deciduous to permanent dentition and during puberty. We also address the finite knowledge on colonization of the oral cavity by microbes other than the bacterial component. Finally, we identify the main outstanding questions that limit our understanding of the acquisition and establishment of a healthy microbiome at an individual level.

Abstract
Objective: The objective of this research was to study the role of music listening by mothers during a cesarean section and the postpartum period to achieve exclusive breastfeeding in the first 6 months. Methods and Study Design: This was a prospective, observational, randomized controlled trial study. A total of 185 singleton pregnant women, in at least 37 weeks of gestation, who were appointed for elective cesarean sections, were recruited. They were randomized into three groups, including pregnant women who did not listen to music (Group 1), listened to music during cesarean section (Group 2), and listened to music during cesarean section and the postpartum room for the first 2 days (Group 3). The breastfeeding results of all three groups were followed up at 7 days, 14 days, and then at months 1, 2, 3, and 6. Results: Success in exclusive breastfeeding among Groups 1, 2, and 3 and Groups 1 and 2 + 3 was not different in every lactating period (7 days-6 months). From subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Mothers who listened to music and had an income of <20,000 baht, an educational level lower than university, planned the pregnancy, had their first pregnancy, and stayed in a private ward had more successful exclusive breastfeeding in a 6-month period than those mothers who did not listen to music, and the difference was statistically significant. Conclusions: Music listening by mothers during a cesarean section and in the postpartum ward did not enhance exclusive breastfeeding during the first 6 months of the postpartum period. However, from subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Thai Clinical Trials Registry number was TCTR20180712001.

Abstract
BACKGROUND The development of an integrated care pathway with multidisciplinary input to standardize and streamline care for pregnant women experiencing breech presentation at 36 or more weeks of gestation poses several challenges because of the divisive and contentious nature of the phenomenon. Although many clinicians are interested in obtaining the skills required to safely support women desiring a vaginal breech birth, the primary trend in most health care facilities is to recommend a cesarean section. OBJECTIVE This paper aims to discuss the mixed methods approach used in a doctoral study conducted to generate new knowledge regarding women's experiences of breech birth in Western Australia and professional recommendations regarding the care of women experiencing breech presentation close to or at term. This study was designed to inform the development of an integrated care pathway for women experiencing a breech presentation. This mixed methods approach situated within the pragmatic paradigm was determined to be the optimal way for incorporating multidisciplinary recommendations with current clinical practice guidelines and consumer feedback. METHODS A mixed methods study utilizing semistructured interviews, an electronic Delphi (e-Delphi) study, and clinical practice guideline appraisal was conducted to generate new data. The interviews were designed to provide insights and understanding of the experiences of women in Western Australia who are diagnosed with a breech presentation. The e-Delphi study explored childbirth professionals' knowledge, opinions, and recommendations for the care of women experiencing breech presentation close to or at term. The clinical practice guideline appraisal will examine the current national and professional breech management and care guidelines. This study has the potential to highlight areas in practice that may need improvement and enable clinicians to better support women through what can be a difficult time. RESULTS Data collection for this study began in November 2018 and concluded in March 2020. Data analysis is currently taking place, and the results will be disseminated through publication when the analysis is complete. CONCLUSIONS The results of this study will guide the development of an integrated care pathway for women experiencing a breech presentation close to or at term, with the hope of moving toward standardized breech care for women in Western Australia. This study protocol has the potential to be used as a research framework for future studies of a similar nature. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) DERR1-10.2196/23514.

Abstract
In recent years, the role of human microbiota as a short- and long-term health promoter and modulator has been affirmed and progressively strengthened. In the course of one’s life, each subject is colonized by a great number of bacteria, which constitute its specific and individual microbiota. Human bacterial colonization starts during fetal life, in opposition to the previous paradigm of the “sterile womb”. Placenta, amniotic fluid, cord blood and fetal tissues each have their own specific microbiota, influenced by maternal health and habits and having a decisive influence on pregnancy outcome and offspring outcome. The maternal microbiota, especially that colonizing the genital system, starts to influence the outcome of pregnancy already before conception, modulating fertility and the success rate of fertilization, even in the case of assisted reproduction techniques. During the perinatal period, neonatal microbiota seems influenced by delivery mode, drug administration and many other conditions. Special attention must be reserved for early neonatal nutrition, because breastfeeding allows the transmission of a specific and unique lactobiome able to modulate and positively affect the neonatal gut microbiota. Our narrative review aims to investigate the currently identified pre- and peri-natal factors influencing neonatal microbiota, before conception, during pregnancy, pre- and post-delivery, since the early microbiota influences the whole life of each subject.

Abstract
The aim of this study was to analyze the association between birth by cesarean section and central adiposity in adolescents in São Luís, Maranhão State, Brazil. This was a cohort study that included 601 participants evaluated at birth and at 18-19 years. At birth we assessed type of delivery, maternal education, family income, maternal marital status, maternal body mass index before pregnancy, prenatal care, maternal smoking habit, gestational age at delivery and intrauterine growth restriction. In the adolescents, we evaluated central adiposity using the dual X-ray energy absorptiometry method. The indicators of central fat used were the trunk-to-total fat mass ratio (T/T), the android-to-gynoid fat mass ratio (A/G), the trunk-to-limb fat mass ratio (T/Lb), and the trunk-to-leg fat mass ratio (T/Lg). A theoretical model for the study of associations was developed using directed acyclic graphs, which allowed selecting the variables that required minimum adjustment for inclusion in the predictive model of exposure to cesarean delivery. The data were analyzed with marginal structural models weighted by the inverse of the probability of selection. A total of 38.6% of the adolescents studied were delivered by cesarean section. There was no significant difference in the central adiposity of adolescents delivered by cesarean section according to the indicators used: T/T ( coefficient = -0.003; 95%CI: -0.013; 0.007), A/G (coefficient = 0.001; 95%CI: -0.015; 0.018); T/Lb (coefficient = -0.016; 95%CI: -0.048; 0.016); T/Lg (coefficient = 0.014; 95%CI: -0.060; 0.030). In conclusion, there was no association between cesarean section delivery and greater central adiposity in the studied adolescents.

Abstract
Rates of delivery by caesarean section (CS) are increasing around the globe and, although several epidemiological associations have already been observed between CS and health outcomes in later life, more are sure to be discovered as this practice continues to gain popularity. The components of vaginal delivery that protect offspring from the negative consequences of CS delivery in later life are currently unknown, although much attention to date has focused on differences in microbial colonisation. Here, we present the case that differing hormonal experiences at birth may also contribute to the neurodevelopmental consequences of CS delivery. Levels of each of the 'birth signalling hormones' (oxytocin, arginine vasopressin, epinephrine, norepinephrine and the glucocorticoids) are lower following CS compared to vaginal delivery, and there is substantial evidence for each that manipulations in early life results in long-term neurodevelopmental consequences. We draw from the research traditions of neuroendocrinology and developmental psychobiology to suggest that the perinatal period is a sensitive period, during which hormones achieve organisational effects. Furthermore, there is much to be learned from research on developmental programming by early-life stress that may inform research on CS, as a result of shared neuroendocrine mechanisms at work. We compare and contrast the effects of early-life stress with those of CS delivery and propose new avenues of research based on the links between the two bodies of literature. The research conducted to date suggests that the differences in hormone signalling seen in CS neonates may produce long-term neurodevelopmental consequences.

Abstract
The aim of this prospective longitudinal study was to examine the association between Cesarean section (CS) and child development and behavior. The sample consisted of 256 children who were born at term without serious perinatal pathologies. Their development and behavior was assessed at the age of four using Ages and Stages Questionnaire (ASQ-3), Children's Behavior Questionnaire and Strength and Difficulties Questionnaire. Multivariate linear regression analyses were conducted to assess the association between CS and child outcomes. CS was associated with better scores in the Problem Solving domain of the ASQ in the whole sample. After stratifying by child sex, the positive association between CS and the Problem Solving domain was significant in boys, while no association was found in girls. Girls were rated less optimally in the Gross Motor domain of the ASQ when born via CS. Mode of birth was not associated with behavioral outcomes.

Abstract
We study the demand-smoothing incentives for private hospitals to perform c-sections. First, we show that a policy change in Chile that increased delivery at private hospitals by reducing the out-of-pocket cost for women with public insurance increased the probability of a c-section by 8.6 percentage points despite private hospitals receiving the same price for a vaginal or cesarean delivery. Second, to understand hospitals' incentives to perform c-sections, we present a model of hospital decisions about the mode of delivery without price incentives. The model predicts that, because c-sections can be scheduled, a higher c-section rate increases total deliveries, compensating the forgone higher margin of vaginal deliveries. Finally, we provide evidence consistent with the demand-smoothing mechanism: hospitals with higher c-section rates are more likely to reschedule deliveries when they expect a high-demand week.

Abstract
Objective: The purpose of this study was to identify trajectories of body mass index (BMI) in toddlers from birth to 2 years old and examine their association with infantile overweight/obesity. Methods: Data were collected from 19,054 children born in any hospital or community healthcare center in Taizhou, China from 2018 to 2019 with at least three BMI measurements after birth. The Latent Class Growth Mixture Model was used to identify distinct BMI trajectories during the first 2 years of infants. Multiple logistic regression models were conducted to explore the associated factors of different BMI trajectories, and log-binomial regression was performed to assess the association between the trajectories and overweight/obesity. Results: Three heterogeneous BMI trajectories were identified and labeled as "lower" (36.21%, n = 6,899), "middle" (53.15%, n = 10,128) and "upper" (10.64%, n = 2,027), respectively. Several characteristics of infants and their corresponding mothers were found to be correlated with infant BMI trajectories, including infant sex, mode of delivery and weight at birth, as well as maternal parity, early pregnancy BMI and status of gestational diabetes mellitus. Furthermore, compared with those in the lower trajectory, infants in the middle [prevalence ratio (PR) = 2.63, 95% confidence interval (95%CI) = 2.17-2.63] or upper (PR = 2.98, 95%CI = 1.51-2.98) trajectory groups were prone to be overweight/obesity at their final observation. Conclusion: Heterogeneous BMI trajectories were observed in our study. Characteristics of both infants and their corresponding mothers could be potential determinants of infant growth. Moreover, infants in the middle and upper trajectory groups were more likely to suffer overweight/obesity.

Abstract
Background Prelacteal feeding (PLF) is a recognised challenge to optimal breastfeeding but remains common in Indonesia. Meanwhile, PLF-related epidemiological research is limited, particularly in this setting. This study examines the prevalence and determinants of overall PLF as well as common PLF types (formula, other milk, and honey) in Indonesia. Methods Data from 6127 mothers whose last child was ≤23-month-old were drawn from the 2017 Indonesia Demographic and Health Survey. Multivariable modified Poisson regression was used to measure the prevalence ratio (PR) for selected PLF risk factors. PLF was defined as anything to drink other than breast milk within three days after birth, before breastmilk flows. Additional analyses were performed on mothers who gave formula, other milk, and honey. Results About 45% babies in Indonesia received PLF with formula being the most frequent (25%), followed by other milk (14%), plain water (5%), and honey (3%). Factors associated with higher prevalence of any PLF were higher wealth quintiles in rural area (PR 1.07; 95% CI 1.03–1.11 per increase in quintile), baby perceived to be small at birth (PR 1.23; 95% CI 1.12–1.35), caesarean deliveries at either public (PR 1.27; 95% CI 1.13–1.44) or private facilities (PR 1.15; 95% CI 1.01–1.31), and not having immediate skin-to-skin contact after birth (PR 1.32; 95% CI 1.23–1.42). PLF was less prevalent among mothers who gave birth to second/subsequent child (PR 0.82; 95% CI 0.76–0.88) and who had an antenatal card (PR 0.89; 95% CI 0.80–0.99). These patterns did not apply uniformly across all PLF types. For example, honey was more common among home births than deliveries at health facilities, but formula and other milk were more common among caesarean deliveries. Conclusions Mapping risk factors for PLF, especially by types, could help to design more targeted interventions to reduce PLF and improve breastfeeding practices in Indonesia.

Abstract
Using data from Spain, we show the impact of significant health-sector budget cuts introduced in 2012 on the rates of cesarean sections and on infant health outcomes at birth, which we use as a proxy for the quality of birth centers. Exploiting a difference-in-differences fixed-effects approach at the hospital level, we estimate a 3% increase in C-sections as a result of the budget restrictions, with no significant consequences on health outcomes at birth. Given the additional evidence in the literature on the negative short- and long-term effects of non-medically indicated C-sections, our paper provides important policy implications for population health. We show the impact of significant budget cuts in the health sector. The outcomes we focus on are the rate of c-sections and infant health at birth. We estimate a 3% increase in cesarean sections as a result of the budgetary cuts. We find no significant consequences on health outcomes at birth.

Abstract
BACKGROUND A large number of studies pointed that being delivered by cesarean section (CS) would affect the health outcomes of offspring, however, whether CS would affect the risk of childhood leukemia remained uncertain. This study conducted a meta-analysis to quantitatively evaluate whether being delivered by CS would influence the onset of childhood leukemia. METHODS PubMed, Embase and Web of Science databases were searched from 3rd June, 1950 to 13th October, 2019 to identify the literature, which examined the relationship between CS and childhood leukemia. This study used Newcastle-Ottawa Scale to assess the quality of literature. Subgroup analyses were conducted on region, mode of delivery, design of the study and number of confounders adjusted. Egger's test and Begg's test were performed to evaluate possible publication bias. RESULTS The pooled odds ratio (OR) estimates illustrated that children delivered by CS had a higher risk of developing leukemia [OR 1.10, 95% confidence interval (CI) 1.04-1.17, P = 0.002] and lymphoblastic leukemia (OR 1.12, 95% CI 1.03-1.23, P = 0.009), while a significant association for myeloid leukemia was not observed (OR 1.05, 95% CI 0.92-1.20, P = 0.451). Results of subgroup analyses indicated that elective CS would increase the risk of childhood lymphoblastic leukemia (OR 1.16, 95% CI 1.06-1.27, P = 0.002). However, a statistical relationship between emergency CS and lymphoblastic leukemia was not observed (OR 1.07, 95% CI 0.93-1.23, P = 0.364). CONCLUSIONS CS would increase the risk of childhood lymphoblastic leukemia. It is worth noting that subgroup analyses shows that elective CS rather than emergency CS increases the risk of lymphoblastic leukemia in offspring.

Abstract
Introduction: The health implications of Caesarean section are a significant factor in evaluating the use of Caesarean section as a method of completing childbirth. The increased rate of Cesarean section augmenting in a statistical way the health implications of the use of Cesarean section as a way of operative technique of childbirth finalization. Aim: To investigate the incidence of health implications on mother and child after Cesarian section in comparison to vaginal delivery. Methods: In our study, which was conducted as a retrospective-prospective and targeted study, the observed research period is from 2007 to 2019. The data sources are: medical histories, birth protocols and neonatal medical histories. Group A: represents the number of surveyed patients with a Cesarean section in a one-year period (2018) in General Hospital „Prim.dr A. Nakaš“. Group B: represents a control group of the same number of patients born by Caesarean section in 2007 in General Hospital „Prim.dr A.Nakaš“ with all parameters and variables detected in the research group. Evaluation of the examinee’s findings includes: anamnestic data, sonographic data, gynecological finding, colposcopic finding. PAPA test, HPV typing and laboratory findings due to the extensiveness of the study. Results: A comparison of the number of Caesarean sections in BiH before and now shows a statistically significant increase from about 6 caesareans per year to almost 21 Cesarean section per year (p<0.05). This increase led to a statistically significant decrease in perinatal mortality from 30 per thousand per year to only 6 per thousand per year (p<0.05). Complications after Cesarean section during both observed periods are dominated by subjective problems, followed by early complications after Cesarean section. According to the types of complications after Caesarean section, hemorrhages were the most numerous during both examined years, with 1 case of other complications and without a statistically significant difference between the observed years. There were no statistically significant differences in the duration of hospitalization, although in 2007 somewhat longer stay in the hospital after Caesarean section was recorded. Conclusion: Our study has shown that one of the most visible trends in modern perinatology is a significant increase in number of Cesarean sections. This is the basis of long-term side effects of Caesarean section, the frequency of which correlates with the increase in this surgical procedure.

Abstract
Purpose To determine whether there is an association between term cesarean breech delivery in the first pregnancy and maternal and neonatal morbidities in the subsequent pregnancy and delivery. Methods We conducted a retrospective, nationwide Finnish population-based cohort study, including all deliveries from January 2000 to December 2017. We included all women with the first two consecutive singleton deliveries of which the first one was a breech delivery regardless of mode of delivery (n = 11,953), and constructed a data set in which the first two deliveries for these women were connected. The outcomes of the second delivery of the women with a first pregnancy that resulted in cesarean breech delivery at term were compared with women whose first pregnancy resulted in a vaginal breech delivery at term. P-value, odds ratio, and adjusted odds ratio were calculated. Results Neonates of a subsequent delivery after cesarean breech delivery had an increased risk for arterial umbilical cord pH below seven, a higher rate of a 5 min APGAR score < 7 and a higher rate of neonatal intensive care unit admission. The women with a history of cesarean section with the fetus in breech presentation were more often in need of a blood transfusion and suffered more often a uterus rupture. In this group, the second delivery was more often a planned cesarean section, an emergency cesarean section, or an instrumental vaginal delivery. Conclusions Primary cesarean breech section in the first pregnancy is associated with adverse neonatal and maternal outcomes in the subsequent delivery.

Association of Cesarean Birth with Body Mass Index Trajectories in Adolescence. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17062003. [PMID: 32197392 PMCID: PMC7142989 DOI: 10.3390/ijerph17062003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 03/12/2020] [Accepted: 03/17/2020] [Indexed: 12/19/2022]
Abstract
Background: This study aimed to identify patterns of body mass index (BMI) changes in adolescence and to assess whether delivery mode (Cesarean and vaginal delivery) was associated with BMI trajectories. Methods: This study was conducted among 569 adolescents aged 10–15 years that resided in the city of Zibo, China. The height and weight of each participant were repeatedly measured at 10, 11, 12, 13, 14 and 15 years. Group based trajectory modeling (GBTM) was used to estimate BMI change trajectories, and multinomial logistic regression was conducted to evaluate the independent association of delivery mode and BMI trajectory classes. Results: Of the 569 participants, 407 (71.5%) were vaginal deliveries and 162 (28.5%) were Cesarean deliveries. Five distinct long-term BMI trajectories were identified: “persistent healthy weight” (57.5%), “persistent underweight” (6.5%), “obesity to healthy weight” (7.8%), “progressive overweight” (10.6%), “progressive obesity” (17.6%). Adjusted multinomial logistic models revealed a twofold increase in risks between ages 10–15 years of “progressive obesity” trajectory (OR = 2.50, 95% CI: 1.42, 4.41) for children born through Cesarean section compared with vaginal birth. Conclusions: Five distinct long-term BMI trajectories were identified during adolescence in our research, and we confirmed that Cesarean birth was significantly increased the risk of “progressive obesity” trajectory but not the “obesity to healthy weight” trajectory.

Postnatal pediatric systemic antibiotic episodes during the first three years of life are not associated with mode of delivery. PLoS One 2020; 15:e0229861. [PMID: 32130278 PMCID: PMC7055886 DOI: 10.1371/journal.pone.0229861] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 02/16/2020] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Delivery by cesarean section (C-section) is associated with adverse short-term and long-term infant outcomes. Given that antibiotics during early life are prescribed for infant outcomes that are more likely among c-section deliveries, we hypothesized that postnatal antibiotic exposure will be greater among c-section infants compared to vaginally delivered infants. OBJECTIVE The aim of this paper was to evaluate if mode of infant delivery was associated with patterns of systemic antibiotic exposure in children during their first three years. METHODS Pediatric electronic health records from UFHealth, 2011 to 2017 were reviewed. We included singleton, term infants (37-42 weeks gestation) with a birth weight ≥ 2500 grams, with documented mode of delivery and well visits on record. Infants with a neonatal intensive care unit stay were excluded. Both oral and intravenous antibiotics for a 10-day duration were classified as a single episode. The primary outcome was antibiotic episodes in the first three years of life, and a sub-analysis was performed to compare broad-spectrum versus narrow-spectrum antibiotic exposures. RESULTS The mean number of antibiotic episodes in 4,024 full-term infants was 0.34 (SD = 0.79) and 24.1% of infants had at least one antibiotic episode. Penicillins were the most prescribed antibiotic in children 0-1 years (66.9%) and cephalosporins were the most common antibiotic prescribed for children 1-3 years (56.2%). We did not detect a meaningful or significant rate ratio (RR) between mode of delivery and overall antibiotic episodes 1.14 (95% CI 0.99, 1.31), broad-spectrum episodes 1.19 (95% CI 0.93, 1.52, or narrow-spectrum episodes 1.14 (95% CI 0.97, 1.34). CONCLUSION Our results do not support the hypothesis that postnatal antibiotic exposure was greater among infants delivered by cesarean section compare to infants delivered vaginally during the first three years of life.

Abstract
Early life environmental risk factors are associated with chronic respiratory morbidity in child- and adulthood. A possible mechanism for this sustained effect is their influence on early life lung functional growth and development, a susceptible phase of rapid lung growth with increased plasticity. We summarize evidence of hereditary and environmental ante-, peri-, and early postnatal factors on lung functional development, such as air pollution, tobacco exposure, nutrition, intrauterine growth retardation, prematurity, early life infections, microbiome, and allergies and their effect on lung functional trajectories. While some of the factors (e.g., prematurity) directly impair lung growth, the influence of many environmental factors is mediated through inflammatory processes (e.g., recurrent infections or oxidative stress). The timing and nature of these influences and their impact result in degrees of impaired maximal lung functional capacity in early adulthood; and they potentially impact future long-term respiratory morbidity such as chronic asthma or chronic obstructive airway disease (COPD). We discuss possibilities to prevent or modify such early abnormal lung functional growth trajectories and the need for future studies and prevention programs.

PLoS Med 2019; 16:e1002996.

Abstract
BACKGROUND Previous studies have suggested that cesarean section (CS) is associated with offspring overweight and obesity. However, few studies have been able to differentiate between elective and nonelective CS, which may differ in their maternal risk profile and biological pathway. Therefore, we aimed to examine the association between differentiated forms of delivery with CS and risk of obesity in young adulthood. METHODS AND FINDINGS Using Swedish population registers, a cohort of 97,291 males born between 1982 and 1987 were followed from birth until conscription (median 18 years of age) if they conscripted before 2006. At conscription, weight and height were measured and transformed to World Health Organization categories of body mass index (BMI). Maternal and infant data were obtained from the Medical Birth Register. Associations were evaluated using multinomial and linear regressions. Furthermore, a series of sensitivity analyses were conducted, including fixed-effects regressions to account for confounders shared between full brothers. The mothers of the conscripts were on average 28.5 (standard deviation 4.9) years old at delivery and had a prepregnancy BMI of 21.9 (standard deviation 3.0), and 41.5% of the conscripts had at least one parent with university-level education. Out of the 97,291 conscripts we observed, 4.9% were obese (BMI ≥ 30) at conscription. The prevalence of obesity varied slightly between vaginal delivery, elective CS, and nonelective CS (4.9%, 5.5%, and 5.6%, respectively), whereas BMI seemed to be consistent across modes of delivery. We found no evidence of an association between nonelective or elective CS and young adulthood obesity (relative risk ratio 0.96, confidence interval 95% 0.83-1.10, p = 0.532 and relative risk ratio 1.02, confidence interval 95% 0.88-1.18, p = 0.826, respectively) as compared with vaginal delivery after accounting for prepregnancy maternal BMI, maternal diabetes at delivery, maternal hypertension at delivery, maternal smoking, parity, parental education, maternal age at delivery, gestational age, birth weight standardized according to gestational age, and preeclampsia. We found no evidence of an association between any form of CS and overweight (BMI ≥ 25) as compared with vaginal delivery. Sibling analysis and several sensitivity analyses did not alter our findings. The main limitations of our study were that not all conscripts had available measures of anthropometry and/or important confounders (42% retained) and that our cohort only included a male population. CONCLUSIONS We found no evidence of an association between elective or nonelective CS and young adulthood obesity in young male conscripts when accounting for maternal and prenatal factors. This suggests that there is no clinically relevant association between CS and the development of obesity. Further large-scale studies are warranted to examine the association between differentiated forms of CS and obesity in young adult offspring.

Abstract
The physiology of how prelabour caesarean section (PCS) and induction of labour (IOL) in comparison to spontaneous vaginal delivery (SVD) has not been fully clarified yet. We measured 201 cord blood (CB) phospholipids and energy metabolites via LC/MS-MS in 109 newborns from the ROLO Kids study; metabolites were compared across the three parturition groups via linear mixed models with correction for multiple testing. In comparison to SVD, PCS babies had lower non-esterified fatty acids (NEFA), including sum of NEFA (p < 0.001), and trends for lower acylcarnitines. The lack of hormonal stimuli, especially catecholamines and cortisol, may underlie the metabolic changes involving gluconeogenesis from fatty acid oxidation (FAO) in PCS born infants. IOL and SVD infants showed no significant differences in metabolites, but ratios estimating carnitine palmitoyltrasferase 1 activity (precursor for FAO) were slightly higher in IOL than in SVD. Thus, IOL does not induce metabolic disadvantage when compared to SVD, though post-natal gluconeogenesis might start earlier due to the artificial solicitation in IOL. These data shed light on the physiology of parturition and may contribute to understand how mode of delivery might modulate future metabolic risks.

Abstract
This study analyses, in children born in twin births, the relationship between reading, writing and arithmetic learning, on the one hand, and type of delivery, on the other, controlling for the effect of interaction and/or confusion of third variables (maternal age at delivery, gestational age, fetal position, birthweight, 1-min Apgar score). In the planned retrospective cohort design, the exposed cohort consisted of children born by caesarean section, and the non-exposed cohort was comprised of children born vaginally. One hundred and twenty-four children born of twin births were evaluated during their first year of primary school: K-BIT tests were used to measure intelligence; the Evalúa-1 battery was used to assess reading, writing, and arithmetic ability; and the children's clinical histories were analysed for obstetric and neonatal variables. After applying binary logistic regressions for each dependent variable, it was found that caesarean delivery in twin births appeared as a possible independent risk factor for specific learning disabilities (LDs) in reading, writing, and arithmetic. Based on these results, further research using larger samples and at more advanced ages is required in order to analyse the influence of obstetric and neonatal variables on the processes underlying specific LDs.
