Association between autism spectrum disorder and peripartum events: a case–control study

Objective:

To assess the association between peripartum events and autism spectrum disorder (ASD) development in children and adolescents.

Methods:

The current research is a case–control study in northern Minas Gerais state, Brazil. The inclusion criteria in the case group included individuals whose medical records reported an autistic disorder diagnosis, individuals had this diagnosis further confirmed by Northern Minas Autistic Support Association and specialized clinics, and their mothers had to answer positively to the question: “Was your child diagnosed with autism spectrum disorder?” in the data collection instrument. Thus, the case group included 253 mothers of children/adolescents of 2–15 years old diagnosed with autism. The inclusion criteria in the control group included 852 individuals belonging to the same age group and enrolled in the same schools as the case group. A semi-structured questionnaire was applied for mothers of children/adolescents, and the multiple logistic regression model was adopted for data analysis. Gross and adjusted Odds Ratios (ORa) were used to estimate the magnitude of the associations.

Results:

Autistic disorder was associated with the presence of meconium in amniotic fluid (AF) (ORa 1.67; 95% confidence interval [95%CI] 1.06–2.65) and cesarean delivery type (ORa 1.65; 95%CI 1.17–2.32). Emergency cesarean section increased autistic disorder development likelihood (ORa 2.38; 95%CI 1.61–3.51). Children and adolescents with ASD were more likely to have been exposed to two or more unfavorable peripartum events and obstetric complications than control groups (ORa 1.59; 95%CI 1.01–2.51).

Conclusions:

Meconium stained amniotic fluid, delivery by cesarean, and two or more unfavorable peripartum events are variables that should be considered in studies about ASD etiology.

Spatial and hierarchical Bayesian analysis to identify factors associated with caesarean delivery use in Ethiopia: Evidence from national population and health facility data

BACKGROUND

Caesarean section has a significant role in reducing maternal and neonatal mortality. A linked analysis of population and health facility data is valuable to map and identify caesarean section use and associated factors. This study aimed to identify geographic variation and associated factors of caesarean delivery in Ethiopia.

METHOD

Linked data analysis of the 2016 Ethiopia Demographic and Health Survey (EDHS) and the 2014 Ethiopian Service Provision Assessment Plus (ESPA+) survey was performed. Spatial analysis was conducted to identify geographic variations and factors associated with caesarean delivery. Hierarchical Bayesian analysis was also performed to identify factors associated with caesarean delivery using the SAS MCMC procedure.

RESULTS

Women's age and education, household wealth, parity, antenatal care (ANC) visits, and distance to caesarean section facility were associated with caesarean delivery use. Women who had ≥4 ANC visits were 4.67 (95% Credible Interval (CrI): 2.17, 9.43) times more likely to have caesarean delivery compared to those who had no ANC visits. Women who had education and were from rich households were also 2.80 (95% CrI: 1.83, 4.19) and 1.80 (95% CrI: 1.08, 2.84) times more likely to have caesarean deliveries relative to women who had no education and were from poor households, respectively. A one-kilometer increase in distance to a caesarean section facility was associated with an 88% reduction in the odds of caesarean delivery (Adjusted Odds Ratio (AOR) = 0.12, 95% CrI: 0.01, 0.78). Hotspots of high caesarean section rates were observed in Addis Ababa, Dire Dawa, and the Harari region. In addition, women's age at first childbirth and ≥4 ANC visits showed significant spatially varying relations between caesarean delivery use across Ethiopia.

CONCLUSION

Caesarean section is a lifesaving procedure, and it is essential to narrow disparities to reduce maternal and neonatal mortality and avoid unnecessary procedures.

Caesarean childbirth and associated factors during Covid-19 pandemic at public hospitals in the Sidama region, Southern Ethiopia

Background

The increasing number of caesarean births worldwide concerns pregnant women, obstetric service providers, and the country's economy. Unnecessary caesarean childbirth increases childbirth complications and the cost of health care in low-income countries, including Ethiopia.

Objective

This study aims to assess caesarean birth and associated factors at the Sidama region public hospitals, Southern Ethiopia, 2020.

Methods

An institution-based cross-sectional study was conducted among 484 women who gave birth at public hospitals in the Sidama region. A multi-stage sampling technique was employed. The data were collected from 1st to 30th of July 2020 by face-to-face interviews using a semi-structured questionnaire (see Table S1: see supplementary materials associated with this article on line), and the wealth index was analysed by principal component analysis. Backward logistic regression used an adjusted odds ratio and a 95% confidence interval to assess the strength and association between the caesarean section and its associated factors. A P-value of < 0.05 was used to declare statistical significance.

Result

Caesarean childbirth in this study was 34.3%. In this study, partograph monitoring (AOR = 2.23, CI = 1.13, 4.38), previous caesarean birth (AOR = 3.21, CI = 1.28,8.17), having genital cutting/mutilation (AOR = 2.51, CI = 1.14,5.53), intermittent cardiotocography monitoring during childbirth (AOR = 2.3, CI = 1.14, 4.49), absence of companionship during delivery (AOR = 4.97, CI = 2.37, 10.43) and is not remembering the last normal menstrual period (AOR = 3.12, CI = 1.40,6.94) had increased the odds of caesarean birth.

Conclusion

Studies show that the prevalence of caesarean has alarmingly increased in both developed and developing countries. However, the magnitude of caesarean section differs from country to country and in rural and urban areas; the magnitude of caesarean section in this study is much higher than the WHO recommends threshold. The local health bureau and obstetric care providers should pay attention to the caesarean section and need intervention in partograph plotting, companionship, cardiotocography, and female genital mutilation.

A national assessment of elective cesarean sections in Bangladesh and the need for health literacy and accessibility

There has been a gradual rise in the number of cesarean sections (CSs) in Bangladesh. The present study identified the cohort of women, who were more likely to opt for an elective CS based on their sociodemographic characteristics, pre-delivery care history, and media exposure, using the Bangladesh Multiple Indicator Cluster Survey-2019. The survey stratification adjusted logistic regression model and interpretable machine learning method of building classification trees were utilized to analyze a sample of 9202 women, alongside district-wise heat maps. One-in-five births (20%) were elective CSs in the 2 years prior to the survey. Women residing in affluent households with educated house-heads, who accessed antenatal care prior to delivery (AOR 4.12; 95% CI 3.06, 5.54) with regular access to media (AOR 1.31; 95% CI 1.10, 1.56) and who owned a mobile phone (AOR 1.25; 95% CI 1.04, 1.50) were more likely to opt for elective CSs, which suggests that health access and health literacy were crucial factors in women’s mode of delivery. Spatial analyses revealed that women living in larger cities had more elective CS deliveries, pointing towards the availability of better health and access to multiple safe delivery options in peripheral areas.

Mean birth weight among term newborns: direction, magnitude and associated factors

A trend towards increasing birth weight has been shown, but factors that explain these trends have not been elucidated. The objectives of this study were to evaluate changes in mean birth weight of term newborns and to identify factors associated with them. All cohorts are population-based studies in which random samples of births (Ribeirão Preto, São Paulo State in 1978/1979, 1994 and 2010; Pelotas, Rio Grande do Sul State in 1982, 1993 and 2004; and São Luís, Maranhão State in 1997/1998 and 2010, Brazil). A total of 32,147 full-term, singleton live births were included. Mean birth weight reduced in the first study period (-89.1g in Ribeirão Preto from 1978/1979 to 1994, and -27.7g in Pelotas from 1982 to 1993) and increased +30.2g in Ribeirão Preto from 1994 to 2010 and +24.7g in São Luís from 1997 to 2010. In the first period, in Ribeirão Preto, mean birth weight reduction was steeper among mothers with high school education and among those born 39-41 weeks. In the second period, the increase in mean birth weight was steeper among mothers with low schooling in Ribeirão Preto and São Luís, females and those born 37-38 weeks in Ribeirão Preto and cesarean section in São Luís. Birth weight decreased in the first study period then increased thereafter. The variables that seem to have been able to explain these changes varied over time.

Identifying the factors associated with cesarean section modeled with categorical correlation coefficients in partial least squares

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

Cesarean delivery among women who gave birth in Dessie town hospitals, Northeast Ethiopia

BACKGROUND

One of the key strategies for reducing maternal and perinatal morbidities and mortalities is the provision of skilled intrapartum care. While cesarean section is an important emergency obstetric intervention for saving the lives of mothers and newborns, a study comparing the prevalence of cesarean delivery is not sufficiently available in Ethiopia. This study aimed at assessing the prevalence and associated factors of cesarean delivery among women who gave birth at hospitals in Dessie town, Northeast Ethiopia.

METHODS

A facility based cross-sectional study was conducted between July and October 2013. A total of 520 women who gave birth in four hospitals (public = 1, private = 3) were interviewed. Face-to-face interviews using a pre-tested and structured questionnaire were conducted for primary data collection. Additionally, patients' charts were reviewed to collect mothers' clinical data. Bivariate and multiple logistic regressions analyses were conducted. Odds ratios and 95% confidence intervals were computed and a P-value of less than 0.05 was taken to declare the level of significance.

RESULTS

A total of 512 mothers were included in the final analysis (response rate = 98.4%), the prevalence of cesarean delivery was found to be 47.6% (95% CI: 44.3, 51.1), While 46 (18.2%) of the procedure conducted in public and 198 (76.1%) were in private hospitals. Partograph monitoring [AOR = 3.84 95%CI: 2.24, 6.59], oxytocin administration [AOR = 4. 80 95%CI: 2.87-8.02], previous cesarean delivery [AOR = 2. 86 95%CI: 1.64-5.01] and place of delivery being a private hospital [AOR = 6. 79 95%CI: 4.18-11.01)] were associated with cesarean delivery.

CONCLUSION

The prevalence of cesarean delivery was found to be high, and was significantly higher in private hospitals than a public facility. There is a need to conduct cesarean delivery audits to appropriately utilize scarce resources. Further an in-depth exploration of the experiences of women with cesarean delivery is necessary.

[The transnationalization of normal childbirth in Brazil: a study of the last five decades]

In recent years, changes have taken place in Brazilian obstetrics in response to the distance between the national scenario and World Health Organization recommendations and the work of organized civil society. This indicates the need for the national and international contexts to be considered. As such, the aim here is to understand the influence of transnationalism on normal childbirth in Brazil. Documental research was conducted to trace out the development of obstetrics in the country. It was found that the historical trajectory of normal childbirth in Brazil has not necessarily been restricted to national borders, but has been influenced by transnational recommendations and standards, orienting the creation of new regulations.

High prevalence of cesarean section births in private sector health facilities- analysis of district level household survey-4 (DLHS-4) of India

Background

Worldwide rising cesarean section (CS) births is an issue of concern. In India, with increase in institutional deliveries there has also been an increase in cesarean section births. Aim of the study is to quantify the prevalence of cesarean section births in public and private health facility, and also to determine the factors associated with cesarean section births.

Methods

We analyzed data from district level household survey data 4 (DLHS-4) combined individual level dataset for 19 states/UTs of India comprising 24,398 deliveries resulting in 22,111 live births for year 2011. The percentages and Chi-square has been computed for the select variables viz. Socio demographic, maternal, antenatal care and delivery related based on type of births (CS Vs normal births). The multiple logistic regression model has been used to identify the potential risk factors associated with CS births.

Results

Of 22,111 live birth analyzed 49.2% were delivered at public sector, 31.9% at private sector and 18.9% were home deliveries. Prevalence of CS births were 13.7% (95% CI; 13.0- 14.3%) and 37.9% (95% CI; 36.7- 39.0%) in the public and private sectors, respectively. Higher odds of CS births were observed with- delivery at private health facility (OR 3.79; 95% C.I 3.06-4.72), urban residence (OR 1.15; 95% C.I 1.00- 1.35), first delivery after 35 years of maternal age (OR 5.5; 95% C.I 1.85- 16.4), hypertension in pregnancy (OR 1.32; 95% C.I 1.06- 1.65) and breach presentation (OR 2.37; 95% C.I. 1.63- 3.43).

Conclusions

Our findings shows that CS births are nearly three times more in private as compared to public sector health facilities.The higher rates of CS births, especially in private sector, not only increase the cost of care but may pose unnecessary risks to women (when there is no indications for CS). The government of India need to take measures to strengthen existing public health facilities as well as ensure that cesarean sections are performed based upon medical indications in both public and private sector health facilities.

Predictors of caesarean section in Northern Ghana: a case-control study

Introduction

Caesarean section rates have become a global public health. This study investigated obstetric and socio-demographic factors associated with caesarean section in northern Ghana.

Methods

This was a case-control study comparing 150 women who had caesarean section (cases) and 300 women who had vaginal delivery (controls). Data were collected retrospectively from delivery registers, postpartum and postnatal registers in the Bolgatanga Regional Hospital. Univariate and multivariate analysis of data were done using SPSS 22.

Results

The study revealed that women who had higher odds of having a caesarean section were women who; attended Antenatal care (ANC) ≥ 4 times (Adjusted OR= 2.99, 95% CI1.762-5.065), were referred from other health facilities (Adjusted OR = 1.19, 95% CI 1.108-1.337) and had a foetal weight of ≥ 4000 grams (Adjusted OR = 1.21, 95% CI 1.064-1.657). There was a slight increase in odds of having a caesarean section among women who had a gestational age > 40 weeks (Adjusted OR = 1.09, 95% CI 1.029-1.281). Women who had secondary/higher education (Adjusted OR = 0.55, 95% CI 0.320-0.941), gestational age < 37 weeks (Adjusted OR = 0.20, 95% CI: 0.100-0.412) and women who had a foetal weight of 1500 grams to 2499 grams (Adjusted OR = 0.17, 95% CI 0.086-0.339) were associated with a lower odds of having a caesarean section.

Conclusion

There was an increase in odds of having a caesarean section among pregnant women who had a foetal weight of ≥ 4000 grams and women who attended ANC ≥ 4 times. Pregnant women who were referred also had increase odds of having a caesarean section.

Cesarean section in Ethiopia: prevalence and sociodemographic characteristics

OBJECTIVE

The objective of this study was to assess the prevalence and sociodemographic characteristics of cesarean section in Ethiopia.

METHODS

We used data collected for Ethiopia Demographic and Health Surveys (DHS) conducted in 2000, 2005, 2011, and 2016. A two-stage, stratified, clustered random sampling design was used to gather information from women who gave birth within the 5-year period before each of the surveys. We analyzed the data to identify sociodemographic characteristics associated with cesarean section using log-Poisson regression models.

RESULTS

The national cesarean section rate increased from 0.7% in 2000 to 1.9% in 2016, with increases across seven of the eleven administrative regions of Ethiopia. Addis Ababa had the highest cesarean section rate (21.4%) in 2016 and the greatest increase since 2000. In the adjusted analysis, women who gave birth in private health facility had a 78.0% higher risk of cesarean section (adjusted prevalence ratio (aPR) (95% CI) 1.78 (1.22, 2.58)) compared with women who gave birth in public health facility. Having four or more births was associated with a lower risk of cesarean section compared with first births (aPR (95% CI) 0.36 (0.16, 0.79)).

CONCLUSIONS

The Ethiopian national cesarean section rate is about 2%, but the rate varies widely among administrative regions, suggesting unequal access. Cesarean sections were highest among urban mothers, first births, births to women with higher education, and births to women from the richest quintile of household wealth.

Factors associated to the type of childbirth in public and private hospitals in Brazil

Abstract Objectives: to estimate the prevalence of cesarean sections and factors associated to the type of childbirth in Brazil. Methods: data on childbirths were collected in Brazil in 2014. Demographic characteristics, related to pregnancy and birth hospital regime (public or private) were evaluation. For each hypothesis raised, the variables were modeled by the binary logistic regression, which the outcome was considered in the type of childbirth. Results: the prevalence of the cesarean sections in Brazil in 2014 was 52.8%; that is 38.1% at public hospitals and 92.8% at private ones. The association between cesarean section and the legal regime at the hospital was highlighted in the logistic model which presented a positive association and interaction between age groups (OR = 23.26; 95% CI= 13.39 - 41.79 for women between 20 and 24 years old and OR = 51.04; 95% CI 31.06 - 84.23 for women aged 35 and over). Conclusions: the performance of childbirth in Brazil meets the routines and recommendations regarding women's health and humanized childbirth established by the Brazilian National Health System policies.

The relationship between indicators of socioeconomic status and cesarean section in public hospitals

OBJECTIVE

To assess the relationship between indicators of socioeconomic status and cesarean section in public hospitals that adopt standardized protocols of obstetrical care.

METHODS

This was a prospective cohort study conducted between May 2005 and January 2006 with 831 pregnant women recruited from 10 public primary care clinics in São Paulo, Brazil. Demographic and clinical characteristics were collected during pregnancy. The three main exposures were schooling, monthly family income per capita, and residential crowding. The main outcome was cesarean section at three public hospitals located in the area. Crude and adjusted risk ratios (RR), with 95% confidence intervals were calculated using Poisson regression with robust variance. We examined the effects of each exposure variable on cesarean section accounting for potential confounders by using four different models: crude, adjusted by mother's characteristics, by obstetrical complications, and by the other two indicators of socioeconomic status.

RESULTS

Among the 757 deliveries performed in the public hospitals, 215 (28.4%) were by cesarean section. In the bivariate analysis, cesarean section was associated with higher family income per capita, higher education, lower residential crowding, pregnancy planning, white skin color, having a partner, and advanced maternal age. In the multivariate analysis, after adjustment for covariates, none of the socioeconomic status variables remained associated with cesarean section.

CONCLUSIONS

In this group, the chance of women undergoing cesarean section was not associated with indicators of socioeconomic status only, but was defined in accordance with major obstetric and clinical conditions.

Maternal and perinatal outcomes after bariatric surgery: a case control study

OBJECTIVE

To compare the results of maternal and perinatal pregnancies of obese women after bariatric surgery.

METHODS

A retrospective cross-sectional study was carried out on 63 women who had undergone bariatric surgery and 73 obese women (control). Demographic data, the characteristics of the bariatric surgery, and the maternal and perinatal results were evaluated. The Student's t-test and chi-square test (χ2) were used to compare the groups. The gestational complications of the prevalence of gestational diabetes mellitus, anemia, and preeclampsia were analyzed using simple and multivariate logistical regression and odd ratios (OD) with their respective confidence intervals (CI) of 95%.

RESULTS

The average body mass index (BMI) at the 1st prenatal appointment of the control group was 34.6±3.3 kg/m2 and that of the post-surgical group was 26.5±4.2 kg/m2. The Roux-en-Y Gastric Bypass was used in 100% of cases; no complications were observed during or after the surgeries. The average weight loss in patients with a prior bariatric surgery was statistically significant (P=0.000). The average weight at birth of the control group was significantly higher than in the post-bariatric surgery group (P=0.017). The women who had a prior bariatric surgery had a higher chance of anemia (OR=3.5; CI 95%: 1.5-8.3) and a reduced chance of macrosomia (OR=0.2; CI 95%:0.1-0.5), and prematurity (OR=0.3; CI 95%:0.1-0.7).

CONCLUSION

Those women who had been submitted to bariatric surgery presented better maternal and perinatal results when compared to obese women.

Factors associated with cesarean delivery in public and private hospitals in a city of northeastern Brazil: a cross-sectional study

Background

To evaluate the prevalence and factors associated with cesarean delivery according to whether care was provided in public or private hospitals in Brazil.

Methods

This was a cross-sectional study based on a cohort of live births between April 2004 and March 2005. A total of 1,344 mother-child pairs were followed up during the first month of life. The variables analyzed were the socioeconomic and demographic characteristics of the mother and newborn, as well as the healthcare provided during pregnancy and childbirth. Hierarchical analysis was carried out for both prediction models, i.e. healthcare provision either within the Brazilian National Health System (public service) or within the private network. Prevalence and association measurement calculations were carried out. Values were considered significant when pless than or equal to 5.0 %.

Results

A total of 1,019 (75,8 %) gave birth in public hospital. The prevalences of cesarean delivery were 29.9 % and 86.2 % in the public and private sectors, respectively. Through hierarchical logistic regression, the risk factors for cesarean delivery presented in the public hospital were maternal age greater than or equal to 20 years (p = 0.003), primiparity (p = 0.004), twinning (p = 0.039), prenatal care provided in the private network (p = 0.004), delivery in hospitals providing high complexity medical care (p = 0.000) and prenatal care with greater than or equal to 6 consultations (p = 0.035). In the private sector, no association was observed between the variables studied and cesarean delivery.

Conclusions

The cesarean delivery rates were high in both sectors, although in the private network the rate was almost triple that of the public service. The absence of determinant factors of birth in the private sector drew attention. In planning measures against the growing cesarean rates, it is necessary to take into consideration the environmental determinants as primiparity, twinning and greater maternal age, frequent indications of primary cesarean delivery, as well as to implement actions that might improve the quality of prenatal and delivery care.

Caesarean section--an appraisal of some predictive factors in Lagos Nigeria

Background

Several maternity units in the developing world lack facilities for caesarean section and often have to transfer patients in extremis. This case controlled study aimed to appraise predictive factors for caesarean section.

Methods

One hundred and fifty two consecutive women with singleton pregnancies who had caesarean section were studied. The next parturient with normal delivery served as control. Variables such as age, parity, marital status, booking status, past obstetric history, weight, height, infant birth weight were assessed. Data obtained were analysed using SPSS 16.0 Windows package.

Results

During the study period, there were 641 deliveries with 257 of them by caesarean section (40.1%).

Logistic regression analysis showed that parity, booking status, maternal height; maternal weight, birth weight, previous caesarean section and ante-partum bleeding were significant predictive factors for caesarean section while maternal age was not.

Conclusions

These predictive factors should be considered in antenatal counseling to facilitate acceptance by at risk women and early referral.

Caesarean delivery in south-western Iran: trends and determinants in a community-based survey

OBJECTIVE

To assess trends in caesarean delivery and its associated factors in south-western Iran.

SUBJECTS AND METHODS

This cross-sectional study was conducted from January 2007 to January 2010 in Fars province, Iran. All deliveries recorded in public and private hospitals were included. The Mann-Whitney U test, χ2 test and multivariate logistic regression models were used for analysis of data. A p value less than 0.05 was considered significant.

RESULTS

The rate of caesarean section for the whole sample of 139,159 increased from 51.6% in 2007 to 53.3% in 2009, which was statistically and clinically significant. The rate of caesarean delivery was significantly higher in primiparous compared to multiparous mothers. The rate increased steadily with the mother's age. The most prevalent recorded reason for caesarean delivery was maternal request. Logistic regression analysis showed that maternal age, previous abortions, underlying maternal disease, gestational age and number of living children were key contributing factors to the choice of mode of delivery.

CONCLUSION

This study showed an increasing rate of caesarean delivery which should draw the attention of policymakers to factors associated with this mode of delivery.

Evolução da assistência materno-infantil e do peso ao nascer no Estado de Pernambuco em 1997 e 2006

Avaliar a evolução e a influência da assistência materno-infantil na variação do peso ao nascer no estado de Pernambuco. Os dados analisados provêm de duas pesquisas transversais da população de crianças menores de cinco anos, estudadas por inquéritos domiciliares em 1997 (n = 1906) e 2006 (n = 1555). A amostra foi calculada para assegurar a representatividade de dois estratos geoeconômicos: setores urbano e rural. Estudou-se a assistência ao pré-natal e parto e o peso ao nascer. Utilizou-se o teste do qui-quadrado para comparar as variáveis categóricas e calculou-se a diferença da média de peso ao nascer nos anos pesquisados, e os respectivos intervalos de confiança de 95%. Verificou-se importante melhora na assistência ao pré-natal e aumento do parto cesáreo. Houve uma redução significante de 112g na diferença da média de peso ao nascer no meio rural. Em 2006 o acesso a pelo menos 1 consulta de pré-natal ocorreu independente da escolaridade materna, no entanto, o acesso ao pré-natal mais adequado foi maior entre as mães de maior escolaridade, tanto em 1997, como em 2006. Apesar da expansão da assistência no pré-natal e no parto, o acesso iníquo, o excesso de intervenções médicas e o aumento da sobrevida de recém nascidos podem estar contribuindo para as variações da média de peso ao nascer no estado de Pernambuco.

[Factors associated with the type of delivery in Brazilian women: 2006 NDHS]

The scope of this paper was to analyze the prevalence of the types of delivery and associated factors in Brazilian women of childbearing age studied in the last National Demographics and Health Survey (NDHS). The study is a national domicile-based cross-sectional analysis, seeking to establish the characteristics of the female population of child-bearing age and of children under 5 years of age. The prevalence of the type of delivery was described according to the following exposition variables: Brazilian macro-regions, location of residence, age, skin color, nutritional status, education, prenatal health unit and place of delivery. The statistical significance (p<0,05) was evaluated using the chi-square test. The population studied consisted of 6.125 women. It was revealed that 42.9% of the women had a caesarean section. Significantly, the prevalence of caesarean section was smaller, irrespective of macro-regions, location of residence, age, skin color, nutritional status, prenatal health unit and place of delivery. The need for further investigation into the factors behind the increase in caesarean sections in Brazil is required in order to reverse this situation, since caesarean section can lead to a series of health complications for both mother and child.

Público versus privado: avaliando a assistência à gestação e ao parto no extremo sul do Brasil

OBJETIVOS: avaliar a assistência à gestação e ao parto entre o setor público e privado no município de Rio Grande, RS. MÉTODOS: aplicou-se questionário padronizado a todas as gestantes residentes neste município que tiveram filho em 2007. Investigaram-se aspectos relativos a cuidados recebidos desde o início da gestação até o pós-parto imediato. A análise estatística consistiu da comparação de proporções nestes dois grupos através do teste de qui-quadrado. RESULTADOS: dentre os 2584 nascimentos cujas mães residiam no município, foram obtidas informações sobre 2557, o que representa 98,9% do total. Destas mães, 96% realizaram pelo menos uma consulta de pré-natal. Gestantes atendidas no setor privado iniciaram o pré-natal mais cedo, realizaram um maior número de consultas médicas, exame de sangue e ultrassonografia pélvica, exame ginecológico, das mamas e citopatológico de colo uterino. Gestantes do setor público realizaram maior número de exames de urina e sorologia para sífilis e foram mais comumente suplementadas com sulfato ferroso. Todas estas diferenças foram estatisticamente significativas (p<0,05). CONCLUSÕES: gestantes do setor privado receberam de forma sistemática melhor assistência durante o pré-natal em termos de consultas e exames realizados, tiveram seu parto mais comumente realizado por médico, foram mais afetadas por intervenções desnecessárias como cesariana e episiotomia e menos frequentemente suplementadas com ferro.

Tabagismo materno durante a gestação e medidas antropométricas do recém-nascido: um estudo de base populacional no extremo sul do Brasil

Este estudo transversal de base populacional teve por objetivo investigar a prevalência de tabagismo materno durante a gestação e seu impacto sobre as medidas antropométricas do recém-nascido. Aplicou-se questionário padronizado a todas as parturientes nas maternidades do Município de Rio Grande, Rio Grande do Sul, Brasil, em 2007. Foram obtidas medidas de peso, comprimento e perímetros cefálico dos recém-nascidos. A prevalência do tabagismo materno na gestação foi de 23%, enquanto a prevalência da exposição passiva ao fumo foi de 29%. Após ajuste para possíveis fatores de confusão, comparados aos recém-nascidos de mães que nunca fumaram, aqueles nascidos de mães fumantes durante toda a gestação tiveram ao nascer, em média, redução de 223,4g (IC95%: 156,7; 290,0) no peso, de 0,94cm (IC95%: 0,60; 1,28) no comprimento e de 0,69cm (IC95%: 0,42; 0,95) no perímetro cefálico. Concluiu-se que a prevalência de tabagismo materno na gestação é alta no Município de Rio Grande. Tabagismo materno durante toda a gestação teve impacto negativo nas medidas antropométricas do recém-nascido.

Modelos de assistência ao parto e taxa de cesárea em diferentes países

Revisão bibliográfica que descreve as taxas de cesárea em diferentes países e os modelos de atenção ao parto de acordo com o uso de tecnologias assistenciais. Foram analisados 60 estudos publicados entre 1999 e 2010, obtidos nas bases de dados da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior e ProQuest. O modelo de assistência obstétrica praticado no país baseia-se na relação médico-paciente, ao grau de utilização de tecnologias e à realização do parto cesáreo.
