Women's experiences in institutional childbirth care in times of the first and second waves of COVID in Mexico. / Experiencias de mujeres en la atención del parto institucional en tiempos de la primera y segunda ola de COVID en México.

This is a qualitative study that explores the perspectives and experiences of a group of Mexican women who experienced institutionalized childbirth care in the first and second waves of the COVID-19 pandemic. Through a semi-structured script, nine women who experienced childbirth care were interviewed between March and October 2020 in public and private hospitals in the city of San Luis Potosí, Mexico. Under the Grounded Theory analysis proposal, it was identified that the health strategies implemented during the pandemic brought with them a setback in the guarantee of humanized childbirth. Women described themselves as distrustful of the protocols that personnel followed to attend to their births in public sector hospitals and very confident in those implemented in the private sector. The intervention of cesarean sections without a clear justification emerged as a constant, as did early dyad separation. Healthcare personnel's and institutions' willingness and conviction to guarantee, protect and defend the right of women to experience childbirth free of violence remain fragile. Resistance persists to rethink childbirth care from a non-biomedicalizing paradigm.

Estudio de tipo cualitativo que explora las perspectivas y experiencias de un grupo de mujeres mexicanas que vivieron la atención institucionalizada del parto en la primera y segunda ola de la pandemia por COVID-19. A través de un guión semiestructurado se entrevistó a nueve mujeres que vivieron la experiencia de la atención del parto entre marzo y octubre de 2020, en hospitales públicos y privados de la ciudad de San Luis Potosí, en México. Bajo la propuesta de análisis de la teoría fundamentada, se identificó que las estrategias sanitarias implementadas en el marco de la pandemia, trajeron consigo un retroceso en la garantía del parto humanizado, las mujeres se narraron desconfiadas en los protocolos que siguió el personal para la atención de sus partos en los hospitales del sector público y muy confiadas en los que se implementaron en el sector privado. La realización de cesáreas sin una justificación clara emergió como una constante, igual que la separación temprana de los binomios. Continúa frágil la disposición y el convencimiento del personal sanitario y las instituciones para garantizar, proteger y defender el derecho de las mujeres a vivir el parto libre de violencia. Persisten resistencias para repensar la atención del parto desde un paradigma no biomédicalizante.

Trends in cesarean section rates in Brazil by Robson classification group, 2014-2020.

OBJECTIVES: to evaluate the trends in cesarean sections from 2014 to 2020 across both public and private sectors, utilizing the Robson Classification. METHODS: this time series study analyzed the proportion of women who underwent cesarean sections between 2014 and 2020, considering both the Robson classification and the type of healthcare service. Trend analysis was conducted using the Prais-Winsten regression. RESULTS: higher proportions of cesarean sections were observed in all Robson groups within the private sector compared to the public sector. This was despite a decreasing trend in the private sector and an increasing trend in the public sector. Notably, elevated proportions of cesarean sections were recorded in groups that are typically favorable to normal childbirth (Robson 1, 4, and 5). CONCLUSIONS: although there was a decreasing trend in cesarean sections within the private sector, an increasing trend was observed in the public sector. Additionally, there was a high proportion of cesarean sections among women with conditions favorable to normal childbirth. It is crucial to continuously monitor these indicators to evaluate and implement interventions aimed at reducing unnecessary cesarean sections.

Association between perinatal and obstetric factors and early age at diagnosis of type 1 diabetes mellitus: a cohort study.

OBJECTIVES: To evaluate the association between perinatal and obstetric factors as potential triggers for the early onset of T1DM. METHODS: This was a retrospective cohort study enrolling 409 patients diagnosed with T1DM, in Bauru, São Paulo, Brazil, from 1981 to 2023. Data were retrieved from medical records, regarding sociodemographic parameters as age, sex, ethnicity, and socioeconomic status. Perinatal and obstetric factors as delivery type, gestational age, filiation order, length of exclusive breastfeeding, maternal age, maternal and fetal blood types, and occurrence of maternal gestational diabetes were also analyzed. An adapted survival analysis was employed to gauge the impact of each assessed variable at the age of T1DM diagnosis. RESULTS: The median age of T1DM diagnosis was 10.3 years with an interquartile range between 6.4 and 15.5 years. Delivery type and filiation order were the only factors statistically significantly associated with an early age at T1DM diagnosis. Patients who were born through cesarean section and who were firstborns showed a 28.6 and 18.0 % lower age at T1DM diagnosis, respectively, compared to those born through vaginal delivery and those that were nonfirstborns. CONCLUSIONS: Being born by cesarean section and being firstborn showed to be statistically significant factors to determine an early T1DM diagnosis.

The effect of birth timing manipulation around carnival on birth indicators in Brazil.

This paper studies the patterns and consequences of birth timing manipulation around the carnival holiday in Brazil. We document how births are displaced around carnival and estimate the effect of displacement on birth indicators. We show that there is extensive birth timing manipulation in the form of both anticipation and postponement that results in a net increase in gestational length and reductions in neonatal and early neonatal mortality, driven by postponed births that would otherwise happen through scheduled c-sections. We also find a reduction in birthweight for high-risk births at the bottom of the weight distribution, driven by anticipation. Therefore, restrictions on usual delivery procedures due to the carnival holiday can be both beneficial and detrimental, raising a double-sided issue to be addressed by policymakers.

Impact of pregestational obesity on perinatal complications: update in a Latin American cohort.

OBJECTIVES: While the association between pregestational obesity and perinatal complications has been established, it is necessary to update the current understanding of its impact on maternal and foetal health due to its growing prevalence. Thus, this study aimed to investigate the association between pregestational obesity with the leading perinatal complications during the last 6 years. STUDY DESIGN: A cross-sectional study was performed in San Felipe, Chile. Anonymised data of 11,197 deliveries that occurred between 2015 and 2021 were included. METHODS: Pregestational body mass index was defined according to the World Health Organisation during the first trimester of pregnancy. The association between pregestational obesity and perinatal complications was analysed by calculating the odds ratio (OR), which was adjusted for confounding variables. Statistical differences were considered with a P-value of <0.05. RESULTS: The prevalence of pregestational obesity was 30.1%. Pregestational obesity was related to a high incidence of perinatal complications (≥3 complications; P < 0.0001). The main perinatal complications were caesarean section, large for gestational age (LGA), gestational diabetes (GD), macrosomia, hypertensive disorders of pregnancy (HDP), premature rupture of membranes (PROM), intrauterine growth restriction, and failed induction. Pregestational obesity was shown to be a risk factor for macrosomia (OR: 2.3 [95% confidence interval {95% CI}: 2.0-2.8]), GD (OR: 1.9 [95% CI: 1.6-2.1]), HDP (OR: 1.8 [95% CI: 1.5-2.1]), LGA (OR: 1.6 [95% CI: 1.5-1.8]), failed induction (OR: 1.4 [95% CI: 1.0-1.8]), PROM (OR: 1.3 [95% CI: 1.1-1.6]), and caesarean section (OR: 1.3 [95% CI: 1.2-1.4]). CONCLUSIONS: Pregestational obesity has been shown to be a critical risk factor for the main perinatal complications in the study population. Pregestational advice is imperative not only in preventing pregestational obesity but also in the mitigation of critical perinatal complications once they arise.

Factores asociados a cesárea en usuarias de una clínica privada en Chile, años 2018 a 2022 / Factors associated with cesarean section in users treated at a private clinic in Chile, years 2018 to 2022

Introducción: De acuerdo con lo reportado por la Organización para la Cooperación y el Desarrollo Económico, Chile posee una de las tasas más altas de cesárea para el continente, llegando a un 44,7% en 2013 y un 47,7% en 2017, ubicándose en tercer lugar, solo precedido por Turquía y México. Objetivo: Analizar los factores relacionados a intervención de cesárea en las mujeres que atendieron su parto en una clínica privada de la Quinta Región de Chile entre los años 2018 y 2022. Método: Estudio transversal analítico en 9041 usuarias. Se utilizó un modelo de regresión logística con odds ratio y sus intervalos de confianza del 95% para evaluar la asociación con variables sociodemográficas y obstétricas. Resultados: La prevalencia de cesárea fue del 85,1% en el periodo estudiado. La condición de gestante primípara, la cesárea previa, la presencia de patología materna o fetal, la ausencia de trabajo de parto y la esterilización quirúrgica presentaron mayor probabilidad de cesárea, mientras que para la edad gestacional, menor o igual a 36 semanas, ésta fue menor. Conclusiones: Destaca un alta prevalencia de cesáreas para el periodo de estudio, superior a lo reportado en la literatura.

Introduction: According to the Organisation for Economic Co-operation and Development, Chile has one of the highest caesarean section rates on the continent, reaching 44.7% in 20132 and 47.7% in 20173 , ranking third only to Turkey and Mexico. Objective: Analyze the factors related to cesarean section intervention in women who delivered in a private clinic in the Fifth Region of Chile, from 2018 to 2022. Method: Cross-sectional study involving 9,041 users. A logistic regression model with odds ratio and its 95% confidence intervals was used to assess associations with sociodemographic and obstetric factors. Results: The prevalence of cesarean section during the study period was 85.1%. Primiparous status, previous cesarean section, presence of maternal and fetal pathology, absence of labor and surgical sterilization were associated with an increased likelihood of cesarean section, while gestational age 36 and under weeks showed a decreased chance. Conclusions: A high prevalence of cesarean sections stands out for the study period, higher than that reported in the literature.

Active but not quiescent lupus nephritis during pregnancy is associated with a higher rate of adverse obstetric outcomes: Analysis of a prospective cohort.

OBJECTIVE: To compare the maternal-fetal/neonatal outcome in patients with systemic lupus erythematosus (SLE) with and without lupus nephritis (LN) in remission or with active disease. METHODS: A prospective cohort of pregnant patients with SLE (ACR 1997 criteria) was studied from January 2009 to December 2021. Demographic, clinical, biochemical, and immunological variables as well as the usual maternal-fetal/neonatal complications were recorded. We compared four groups according to the status of SLE during pregnancy: patients with quiescent SLE without lupus nephritis, patients with active SLE without lupus nephritis, patients with quiescent lupus nephritis, and patients with active lupus nephritis. Statistical analysis included descriptive statistics, bivariate analysis, and Cox regression analysis. RESULTS: A total of 439 pregnancies were studied, with a median age of 28 ± 6, SLE duration of 60 months (interquartile range 36-120). A higher frequency of maternal and fetal/neonatal complications was observed in patients with active SLE with or without lupus nephritis. Multivariate analysis showed that active LN was a risk factor for gestational hypertension (hazard ratios [HR] 1.95; 95% confidence intervals [CI]: 1.01-6.39), premature rupture of membranes (HR 3.56; 95% CI: 1.79-16.05) and more frequent cesarean section (HR 1.82; 95% CI: 1.13-2.94). CONCLUSION: LN is associated with a higher frequency of maternal complications, especially in those patients with active disease during pregnancy, and those maternal complications had an impact on poor fetal/neonatal outcomes. Strict control and timely care of LN could improve the obstetric prognosis.

Obstetric risk profiles and causes of death: Estimating their association with cesarean sections among maternal deaths in Mexico.

BACKGROUND: Maternal mortality is a critical indicator of healthcare quality, and in Mexico, this has become increasingly concerning due to the stagnation in its decline, alongside a concurrent increase in cesarean section (C-section) rates. This study characterizes maternal deaths in Mexico, focusing on estimating the association between obstetric risk profiles, cause of death, and mode of delivery. METHODS: Utilizing a retrospective observational design, 4,561 maternal deaths in Mexico from 2010-2014 were analyzed. Data were sourced from the Deliberate Search and Reclassification of Maternal Deaths database, alongside other national databases. An algorithm was developed to extract the Robson Ten Group Classification System from clinical summaries text, facilitating a nuanced analysis of C-section rates. Information on the reasons for the performance of a C-section was also obtained. Logistic regression and multinomial logistic regression models were used to estimate the relation between obstetric risk factors, mode of delivery and causes of maternal death, adjusting for covariates. RESULTS: Among maternal deaths in Mexico from 2010-2014, 47.1% underwent a C-section, with a significant history of previous C-sections observed in 31.4% of these cases, compared to 17.4% for vaginal deliveries (p<0.001). Early prenatal care in the first trimester was more common in C-section cases (46.8%) than in vaginal deliveries (38.3%, p<0.001). A stark contrast was noted in the place of death, with 82.4% of post-C-section deaths occurring in public institutions versus 69.1% following vaginal births. According to Robson's classification, the highest C-section rates were in Group 4 (67.2%, p<0.001) and Group 8 (66.9%, p<0.001). Logistic regression analysis revealed no significant difference in the odds of receiving a C-section in private versus other settings after adjusting for Robson criteria (OR: 1.21; 95% CI: 0.92, 1.60). A prior C-section significantly increased the likelihood of another (OR: 2.38; CI 95%: 2.01, 2.81). The analysis also indicated C-sections were significantly tied to deaths from hypertensive disorders (RRR = 1.25, 95% CI [1.12, 1.40]). In terms of indications, 6.3% of C-sections were performed under inadequate indications, while the indication was not identifiable in 33.1% of all C-sections. CONCLUSIONS: This study highlights a significant overuse of C-sections among maternal deaths in Mexico (2010-2014), revealed through the Robson classification and ana analysis of the reported indications for the procedure. It underscores the need for revising clinical decision-making to promote evidence-based guidelines and favor vaginal deliveries when possible. High C-section rates, especially noted disparities between private and public sectors, suggest economic and non-clinical factors may be at play. The importance of accurate data systems and further research with control groups to understand C-section practices' impact on maternal health is emphasized.

Neonatal screening of ABO/RhD blood group and direct antiglobulin Coombs test. Experience of a single institution.

BACKGROUND: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth. METHODS: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included. The ABO/RhD and DAT group was determined in umbilical cord samples or the first 24 hours of life. Demographic, maternal, and neonatal variables were recorded. The association between the variables was estimated using the odds ratio (OR). RESULTS: 8721 pairs were included. The DAT was positive in 239 newborns (2.7%), with the variables associated with positive PDC being maternal age > 40 years (OR: 1.5; 95% CI: 1.0 to 2.3), birth by cesarean section (1.4; 1.1-2.0), mother group O (6.4; 3.8-11.8), prematurity (3.6; 2.6-5.0), birth weight < 2500 g (2.1; 1.6-2.8), newborn group A (15.7; 10.7-23.1) and group B (17.6; 11.4-27.2), hemoglobin at birth < 13.5 g/dl (4.5; 2.8-7.1) and reticulocytosis > 9% (1.9; 1.2 to 3.1). DISCUSSION: The frequency of neonatal positive PDC was 2.7%, with a significant association with maternal/neonatal incompatibility to the ABO and RhD group, with a substantial impact on various neonatal variables. These results support the policy of universal implementation at the birth of the ABO/RhD and DAT determination.

INTRODUCCIÓN: La determinación del grupo sanguíneo ABO/RhD y la prueba directa de Coombs (PDC) al nacimiento son una práctica recomendada, pero existe variabilidad en su implementación universal. Se presentan los resultados de la determinación al nacimiento del grupo ABO/RhD y la PDC en una cohorte institucional. MÉTODOS: Se incluyeron los recién nacidos entre 2017 y 2020 en un hospital de atención a embarazos de alto riesgo. Se determinó el grupo ABO/RhD y se realizó la PDC en muestras de cordón umbilical o en las primeras 24 horas de vida. Se registraron las variables demográficas, maternas y neonatales. Se estimó la asociación entre las variables mediante la razón de probabilidad (OR). RESULTADOS: Se incluyeron 8721 binomios. La PDC fue positiva en 239 recién nacidos (2.7%), siendo las variables asociadas a la PDC positiva la edad materna > 40 años (OR: 1.5;IC95%: 1.0-2.3), el nacimiento por vía cesárea (1.4; 1.1-2.0), la madre del grupo O (6.4; 3.8-11.8), la prematuridad (3.6; 2.6-5.0); el peso al nacer < 2500 g (2.1; 1.6-2.8); el neonato del grupo A (15.7; 10.7-23.1) o del grupo B (17.6; 11.4-27.2), la hemoglobina al nacer < 13.5 g/dl (4.5; 2.8-7.1) y la reticulocitosis > 9% (1.9; 1.2 a 3.1). DISCUSIÓN: La frecuencia de PDC positiva neonatal es del 2.7%, con asociación significativa la incompatibilidad materna/neonatal al grupo ABO y RhD, con impacto significativo en diversas variables neonatales. Estos resultados apoyan la política de implementación universal al nacimiento de la determinación de ABO/RhD y PDC.

Prevalence of different variations of non-consented care during the childbirth process in Mexico by geographical regions: comparing ENDIREH survey data from 2016 to 2021.

INTRODUCTION: Non-consented care, a form of obstetric violence involving the lack of informed consent for procedures, is a common but little-understood phenomenon in the global public health arena. The aim of this secondary analysis was to measure the prevalence and assess change over time of non-consented care during childbirth in Mexico in 2016 and 2021, as well as to examine the association of sociodemographic, pregnancy-, and childbirth-factors with this type of violence. METHODS: We measured the prevalence of non-consented care and three of its variations, forced sterilization or contraception, forced cesarean section, and forced consent on paperwork, during childbirth in Mexico for 2016 (N = 24,036) and 2021 (N = 19,322) using data from Mexico's cross-sectional National Survey on the Dynamics of Household Relationships (ENDIREH). Weighted data were stratified by geographical regions. We performed adjusted logistic regression analyses to explore associations. RESULTS: The national prevalence of non-consented care and one of its variations, pressure to get a contraceptive method, increased from 2016 to 2021. A decrease in the prevalence was observed for forced contraception or sterilization without knowledge, forcing women to sign paperwork, and non-consented cesarean sections nationally and in most regions. Women between the ages of 26 and 35 years, married, cohabiting with partner, living in urban settings, who do not identify as Indigenous, and who received prenatal services or gave birth at the Mexican Institute of Social Security (IMSS) facilities experienced a higher prevalence of non-consented care. Being 26 years of age and older, living in a rural setting, experiencing stillbirths in the last five years, having a vaginal delivery, receiving prenatal services at IMSS, or delivering at a private facility were significantly associated with higher odds of reporting non-consented care. CONCLUSION: While a decrease in most of the variations of non-consented care was found, the overall prevalence of non-consented care and, in one of its variations, pressure to get contraceptives, increased at a national and regional level. Our findings suggest the need to enforce current laws and strengthen health systems, paying special attention to the geographical regions and populations that have experienced higher reported cases of this structural problem.

Association between location of prenatal care services and non-consented cesarean sections in Mexico: A secondary analysis of the National Survey on the Dynamics of Household Relationships 2016.

BACKGROUND: Mexico has one of the world's highest rates of cesarean section (C-section). Little is known about Mexico's frequency of and risk factors for non-consented C-sections, a form of obstetric violence. We examined the prevalence of sociodemographic and obstetric-specific characteristics of Mexican women who delivered via C-section, as well as the association between the location of prenatal care services and experiencing a non-consented C-section. METHODS: We conducted a secondary analysis of data collected from Mexico's 2016 National Survey on the Dynamics of Household Relationships (ENDIREH 2016) of women who reported a C-section during their latest delivery. Adjusted logistic regressions were calculated to explore the associations between the location of prenatal care services and experiencing a non-consented cesarean delivery, stratifying by Indigenous belonging. RESULTS: The sample size for this analysis was 10,256 ENDIREH respondents, with 9.1% not consenting to a C-section. ENDIREH respondents between the ages of 26 and 35 years old, living in urban settings, living in Central or Southern Mexico, and married or living with a partner experienced a higher prevalence of non-consented C-sections. For both women who identified as Indigenous and those who did not, the odds of experiencing a non-consented C-section were higher when receiving prenatal services in private settings. Receiving more than one type of prenatal service was also associated with increased odds of non-consented C-sections, while ENDIREH 2016 respondents who did not identify as Indigenous and received prenatal care at the State Institute for Social Security and Services for State Workers facility had lower odds of experiencing a non-consented C-section. CONCLUSIONS: This analysis indicates that receiving prenatal care at a private facility or a combination of public and private services increases the risk of experiencing a non-consented C-section in Mexico. Additional research is required to further understand the factors associated with non-consented C-sections in Mexico.

Partos y cesáreas en edad de riesgo en hospitales del Maule desde 2017 a 2021 / Births and cesarean sections at risk age in Maule hospitals from 2017 to 2021

Pregnancy, despite being a physiological process, can lead to morbidity and mortality, which is increased at risk ages, defined as younger or equal to15 years and older or equal to 35 years. For an adequate approach it is necessary to know the local reality of the population, therefore, the objective of this study is to describe and analyze the discharges of births and cesarean sections at risk age in the Maule Region from 2017 to 2021 using the database collected from the Biostatistics Unit of the Maule Health Service, which includes the hospitals of the region. Within the observed period, a total of 30,599 deliveries and cesarean sections were studied, being these a total of 5,581 at risk age, of which 0.65% corresponds to women younger or equal to 15 years and 17.57% to women older or equal to 35 years. There is a downward tendency in births in general, mostly evidenced in less or equal to 15 years, and on the contrary, a rise in births and cesarean sections of more or equal to 35 years, differing with the statistics at the country level. The tendency of increasing maternal age of pregnancies in the Maule region and its consequences are a fundamental factor when planning new public policies, so we consider it of vital importance to promote research and update the evidence, with a focus on the local population.

El embarazo a pesar de ser un proceso fisiológico puede conllevar morbimortalidad, la cual se acrecienta en edades de riesgo, definida como menor o igual a 15 años y mayor o igual a 35 años. Para el adecuado enfrentamiento se necesita conocer la realidad local, por ello, el objetivo de este estudio es describir y analizar los egresos de partos y cesáreas en edad de riesgo en la Región del Maule desde el año 2017 a 2021 utilizando la base de datos recogida desde la Unidad de Bioestadística del Servicio de Salud Maule, la cual incluye los hospitales de la región. Dentro del periodo observado se estudió un total de 30.599 partos y cesáreas, siendo estos un total de 5.581 en edad de riesgo, de los cuales 0.65% corresponde a mujeres menores o igual a 15 años y 17.57% a mujeres mayores o igual a 35 años. Existe una tendencia a la baja de los nacimientos en general, mayormente evidenciado en menores o igual a 15 años, y por el contrario, un alza en los partos y cesáreas de mayores o igual a 35 años, difiriendo con las estadísticas a nivel país. El aumento de la edad materna de los embarazos en la región del Maule y sus consecuencias son un factor fundamental a la hora de planificar nuevas políticas públicas, por lo que consideramos de vital importancia promover la realización de investigaciones y actualización de la evidencia sobre el tema, con un enfoque en la población local.

An implementation analysis of a quality improvement project to reduce cesarean section in Brazilian private hospitals.

BACKGROUND: Brazil has one of the highest prevalence of cesarean sections in the world. The private health system is responsible for carrying out most of these surgical procedures. A quality improvement project called Adequate Childbirth Project ("Projeto Parto Adequado"- PPA) was developed to identify models of care for labor and childbirth, which place value on vaginal birth and reduce the frequency of cesarean sections without a clinical indication. This research aims to evaluate the implementation of PPA in private hospitals in Brazil. METHOD: Evaluative hospital-based survey, carried out in 2017, in 12 private hospitals, including 4,322 women. We used a Bayesian network strategy to develop a theoretical model for implementation analysis. We estimated and compared the degree of implementation of two major driving components of PPA-"Participation of women" and "Reorganization of care" - among the 12 hospitals and according to type of hospital (belonging to a health insurance company or not). To assess whether the degree of implementation was correlated with the rate of vaginal birth data we used the Bayesian Network and compared the difference between the group "Exposed to the PPA model of care" and the group "Standard of care model". RESULTS: PPA had a low degree of implementation in both components "Reorganization of Care" (0.17 - 0.32) and "Participation of Women" (0.21 - 0.34). The combined implementation score was 0.39-0.64 and was higher in hospitals that belonged to a health insurance company. The vaginal birth rate was higher in hospitals with a higher degree of implementation of PPA. CONCLUSION: The degree of implementation of PPA was low, which reflects the difficulties in changing childbirth care practices. Nevertheless, PPA increased vaginal birth rates in private hospitals with higher implementation scores. PPA is an ongoing quality improvement project and these results demonstrate the need for changes in the involvement of women and the care offered by the provider.

Pre-pregnancy body mass index and caesarean section in Andean women in Peru: a prospective cohort study.

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.

[Factors associated with breastfeeding at birth in maternity hospitals linked to the Rede Cegonha, Brazil, 2016-2017]. / Fatores associados ao aleitamento materno ao nascer em maternidades vinculadas à Rede Cegonha, Brasil, 2016-2017.

Breastfeeding (BF) is a human right, and it must start from birth. The adequacy of Rede Cegonha (RC) strategies can contribute to the promotion of BF. The objective was to identify factors associated with BF in the first and 24 hours of live births at full-term maternity hospitals linked to CR. Cross-sectional study with data from the second evaluation cycle 2016-2017 of the RC that covered all of Brazil. Odds ratios were obtained through binary logistic regression according to a hierarchical model, with 95% confidence intervals and p-value < 0.01. The prevalence of BF in the first hour was 31% and in the 24 hours 96.6%. The chances of BF in the first hour increased: presence of a companion during hospitalization, skin-to-skin contact, vaginal delivery, delivery assistance by a nurse and accreditation of the unit in the Baby-Friendly Hospital Initiative. Similar results at 24 hours, and association with maternal age below 20 years. BF in the first hour was less satisfactory than in the 24 hours, probably due to the high prevalence of cesarean sections, a factor associated with a lower chance of early BF. Continuous training of professionals about BF and the presence of an obstetric nurse during childbirth are recommended to expand BF in the first hour.

O aleitamento materno (AM) é um direito humano e deve ser iniciado desde o nascimento. A adequação das estratégias da Rede Cegonha (RC) pode contribuir na promoção do AM. O objetivo foi identificar os fatores associados ao AM na primeira e nas 24 horas de nascidos vivos a termo em maternidades vinculadas à RC. Estudo transversal com dados do segundo ciclo avaliativo 2016-2017 da RC, que abrangeu todo o Brasil. Foram obtidas razões de chance por meio de regressão logística binária segundo modelo hierarquizado, com intervalos de confiança a 95% e p-valor < 0,01. A prevalência de AM na primeira hora foi de 31%, e nas 24 horas, de 96,6%. Aumentaram as chances de AM na primeira hora: presença de acompanhante na internação, contato pele a pele, parto vaginal, assistência ao parto por enfermeira e acreditação da unidade na Iniciativa Hospital Amigo da Criança. Resultados semelhantes nas 24 horas, e associação com idade materna inferior a 20 anos. O AM na primeira hora foi menos satisfatório do que nas 24h, provavelmente pela elevada prevalência de cesariana, fator associado à menor chance de AM precoce. A capacitação dos profissionais sobre AM de forma contínua e a presença de enfermeiro obstetra no parto são recomendadas para ampliar o AM na primeira hora.

Análisis de la tasa de cesáreas por grupos de Robson en Clínica Universidad de los Andes / Analysis of the cesarean section rate by Robson's groups at Clínica Universidad de los Andes

Introducción: La tasa de cesáreas es importante para cualquier centro de atención hospitalaria. Es un indicador de calidad utilizado en muchas publicaciones y, aunque no es una estadística vital, se ha reconocido como un indicador de la calidad de atención. Objetivo: Conocer la tasa de cesáreas en una institución utilizando los grupos de Robson. Métodos: Estudio retrospectivo de bases de datos de la maternidad. Se consideraron las variables de paridad, cesárea anterior, trabajo de parto, inducción, para poder clasificar la población según los grupos de Robson. El análisis consideró los nacimientos desde octubre del 2014 hasta junio del 2021. Resultados: Se observó una tasa de 27,9% en el periodo de estudio. El grupo 5 de Robson, que considera pacientes con una o más tasa de cesáreas, mostró una elevada tasa (68%), contribuyó con el 36% de todas las cesáreas, siendo solamente el 15% de la población. El grupo 3, de multíparas con trabajo de parto espontáneo, tuvo una tasa del 1,8%, contribuyó al 0,4% de las cesáreas, siendo el 20% de la población de estudio. Se encontró una correlación significativa entre uso de parto instrumental y menor tasa de cesáreas, al realizar análisis por operador (Spearman rho: -0,45; IC95%: -0,788 a -0,0190; p = 0,043). Conclusión: La tasa de cesáreas observada fue 27,9%, y las pacientes con cesárea anterior son un grupo donde pueden concentrarse mayores esfuerzos para bajar la tasa global. Entre los operadores, los usuarios de parto instrumental tuvieron menor proporción cesáreas.

Introduction: The cesarean section rate is important for any hospital care center. It is a quality indicator used in many publications, and although not a vital statistic, it has been recognized as an indicator of the quality of care. Objective:: To know the cesarean section rate in an institution using Robson groups. Methods: Retrospective study of maternity databases. The variables of parity, previous cesarean section, labor, induction was considered in order to classify the population according to Robson groups. The analysis considered births from October 2014 to June 2021. Results: A rate of 27.9% was observed in the study period. Robson's group 5, which considers patients with one or more rate of cesarean sections, showed a high rate (68%), contributing to 36% of all cesarean sections, being only 15% of the population. Group 3, multiparas with spontaneous labor, had a rate of 1.8%, contributing to 0.4% of cesarean sections, making up 20% of the study population. A significant correlation was found between the use of instrumental delivery and a lower rate of cesarean sections, when analyzing by operator (Spearman rho: -0.45; IC95%: -0.788 to -0.0190; p = 0.043). Conclusion: The observed cesarean section rate was 27.9%, and patients with a previous cesarean section are a group where greater efforts can be concentrated to lower the overall rate. Among the operators, users of instrumental delivery had a lower proportion of cesarean sections.

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 (ß=+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. CLINICAL TRIAL REGISTRY: The QUALI-DEC trial is registered on the Current Controlled Trials website (https://www.isrctn.com/) under the number ISRCTN67214403.

Cesarean sections and sociodemographic disparities in Ecuador: A nationwide study from hospital registries between 2015 and 2022.

OBJECTIVE: This study aimed to analyze sociodemographic factors associated with cesarean sections (c-sections) in Ecuador. METHODS: Data were extracted from the Ecuadorian National Institute of Statistics and Censuses (INEC). Multivariate binary and multinomial logistic regression analyses were performed to assess sociodemographic factors associated with c-sections overall and with each type of c-section (elective or emergency c-section). RESULTS: This study included 1 118 842 in-hospital deliveries during 2015-2022 in Ecuador, of which 41.3% were c-sections. This exceeds the recommended levels of medical justified c-sections. Those who were older than 20-29 years showed a higher probability for c-sections overall. Regarding ethnicity, Montubios had 57% higher probability for c-sectioned with an adjusted odds ratio (aOR) of 1.57 and a 95% confidence interval (CI) of 1.45-1.71; while indigenous, black, and white individuals exhibited 73%, 29%, and 21% lower probabilities, respectively. However, this varied according to specific type of c-sections: black individuals had 11% higher probability of elective c-section but 44% lower probability of emergency c-section. Deliveries in private healthcare facilities exhibited significantly higher probabilities of c-sections overall (aOR 15.38, 95% CI 15.20-15.56). Higher probability of emergency c-section was also observed during 2020-2022. CONCLUSION: Cesarean sections in Ecuador still exceed the recommended levels of medically justified c-sections, highlighting the importance of adopting an approach to childbirth that reduces unnecessary interventions. These results suggest an important role of sociodemographic factors, which aligns with the reported need for multicomponent and locally tailored strategies for addressing c-section overuse. The increase in c-sections during the COVID-19 pandemic (2020-2022) might suggest the influence of external health crises on maternal healthcare.

Trends in Cesarean Delivery in Puerto Rico, 2018-2022.

Cesarean delivery is major surgery associated with higher costs and adverse outcomes, such as surgical complications, compared with vaginal delivery (1-3). The cesarean delivery rate in Puerto Rico rose from just over 30% in the early to mid-1990s to over 40% by the early 2000s (4,5). During this time, cesarean delivery rates in Puerto Rico were 40%-70% higher than rates in the U.S. mainland and up to 78% higher than rates for Hispanic women in the U.S. mainland (4,5). This report describes trends in Puerto Rico's cesarean delivery rate from 2010 to 2022 and explores changes by maternal age, gestational age, and municipality from 2018 to 2022.
