Inequalities in cesarean delivery rates by ethnicity and hospital accessibility in Brazil

Future Possible Changes in Medically Underserved Areas in Japan: A Geographic Information System-Based Simulation Study

BACKGROUND

A decrease in populations could affect healthcare access and systems, particularly in medically underserved areas (MUAs) where depopulation is becoming more prevalent. This study aimed to simulate the future population and land areas of MUAs in Japan.

METHODS

This study covered 380,948 1 km meshes, 87,942 clinics, and 8354 hospitals throughout Japan as of 2020. The areas outside a 4 km radius of medical institutions were considered as MUAs, based on the measure of areas in the current Japanese Medical Care Act. Based on the population estimate for a 1 km mesh, the population of mesh numbers of MUAs was predicted for every 10 years from 2020 to 2050 using geographic information system analysis. If the population within a 4 km radius from a medical institution fell below 1000, the institution was operationally assumed to be closed.

RESULTS

The number of MUAs was predicted to decrease from 964,310 (0.77% of the total Japanese population) in 2020 to 763,410 (0.75%) by 2050. By 2050, 48,105 meshes (13% of the total meshes in Japan) were predicted to be new MUAs, indicating a 31% increase in MUAs from 2020 to 2050. By 2050, 1601 medical institutions were tentatively estimated to be in close proximity.

CONCLUSIONS

In Japan, the population of MUAs will decrease, while the land area of MUAs will increase. Such changes may reform rural healthcare policy and systems.

Cesarean delivery and risk of HIV vertical transmission in Southern Brazil, 2008-2018

BACKGROUND

Childbirth via cesarean delivery can prevent intrapartum vertical transmission for women who are not virally suppressed at the time of delivery. Few studies have compared cesarean delivery trends between women living with HIV and women without HIV and have examined the role of cesarean delivery in the prevention of vertical transmission in the era of potent combination antiretroviral therapy.

OBJECTIVE

We hypothesized that the cesarean delivery rate is high in women living with HIV compared with women without HIV and that cesarean delivery usage decreases over time among women living with HIV with advances in combined antiretroviral therapy in a country with a high national cesarean delivery rate. This study aimed (1) to evaluate cesarean delivery trends in women with and without HIV and (2) to examine its role in preventing vertical transmission among women living with HIV in a setting of free, universal combined antiretroviral therapy coverage in a retrospective cohort of nearly 56,000 deliveries at a major referral institution in a city with the highest prevalence of maternal HIV in Brazil.

STUDY DESIGN

Data from maternal-infant pairs from January 1, 2008, to December 31, 2018, were extracted. Cesarean delivery rates were compared using the Pearson chi-square test. Cesarean delivery predictors were evaluated by multivariate log-linear Poisson regression using a generalized estimating equations approach. HIV viral suppression was defined as a viral load of <1000 copies/ml at delivery. HIV vertical transmission was determined following national guidelines.

RESULTS

Over 11 years, 48,688 pregnancies occurred in 40,375 women; HIV seroprevalence was 2.7%; 18,886 cesarean deliveries (38.8%) were performed; 47.7% of women living with HIV and 38.6% of women without HIV underwent cesarean delivery (P<.001). Although HIV was associated with cesarean delivery (adjusted relative risk, 1.17 [95% confidence interval, 1.05-1.29]), women living with HIV with vertical transmission achieved similar cesarean delivery rates (36.7%) as women without HIV (39.8%) in 2018. Cesarean delivery in women living with HIV with an unknown viral load at delivery (42.6%) did not increase over time. HIV vertical transmission rate was 2.2%, the highest in women living with HIV with an unknown viral load (8.4%) vs women living with HIV without vertical transmission (4.1%) and women living with HIV with vertical transmission (0.5%) (P<.001).

CONCLUSION

In the HIV epicenter of Brazil, women living with HIV with vertical transmission had fewer surgical deliveries, likely because of the use of potent combination antiretroviral therapy. Nearly half of the women living with HIV with an unknown viral load did not undergo cesarean delivery, a potential missed opportunity for the prevention of HIV vertical transmission.

Geographical variability and factors associated with caesarean section delivery in India: a comparative assessment of Bihar and Tamil Nadu

Background

Caesarean section delivery is a major life-saving obstetric surgical intervention for mothers and babies from pregnancy and childbirth related complications. This paper attempts to investigate the geographical variations and correlating factors of caesarean section delivery in India, particularly focusing on the states of Bihar and Tamil Nadu, accounting for one of the lowest and highest prevalence states of caesarean section delivery respectively.

Methods

This study is based on secondary data, collected from the fourth round of the National Family Health Survey (NFHS-4), 2015–16. We utilized 190,898 women aged 15–49 years who had a living child during the past 5 years preceding the survey. In this study, caesarean section delivery was the outcome variable. A variety of demographic, socio-economic, and pregnancy- and delivery-related variables were considered as explanatory variables. Descriptive statistics, bivariate percentage distribution, Pearson’s Chi-square test, and multivariate binary logistic regression models were employed to draw the inferences from data.

Results

Of participants, about 19% of women had undergone caesarean section delivery in the country. The state-wise distribution shows that Telangana (60%) followed by Andhra Pradesh (42%) and Tamil Nadu (36%) represented the topmost states in caesarean delivery, while Bihar (7%), Madhya Pradesh (10%), and Jharkhand (11%) placed at the bottom end. Multivariate logistic models show that the likelihood of caesarean delivery was higher among older women (35–49 years), women with higher levels of education, Muslims, women belonging to the upper quintiles of the household wealth, and those who received antenatal care (ANC), experienced pregnancy loss and delivery complications. Moreover, the odds of caesarean section delivery were remarkably greater for the private health sector than the public health sector in both focused states: Bihar (odds ratio [OR] = 12.84; 95% confidence interval [CI]: 10.90, 15.13) and Tamil Nadu (OR = 2.90; 95% CI: 2.54, 3.31).

Conclusion

Findings of this study suggest that improvement in female education, providing economic incentives, and spreading awareness through mass media could raise the caesarean section delivery among women whose vaginal delivery could be unsafe for them as well as for their babies. Moreover, providing adequate ANC and well-equipped public healthcare services would facilitate caesarean delivery among needy women.

Trend and Sociodemographic Correlates of Cesarean Section Utilization in Nepal: Evidence from Demographic and Health Surveys 2006-2016

BACKGROUND

Addressing inequalities in accessing emergency obstetric care is crucial for reducing the maternal mortality ratio. This study was undertaken to examine the time trends and sociodemographic correlates of cesarean section (CS) utilization in Nepal between 2006 and 2016. Methods. Data from the Nepal Demographic and Health Surveys (NDHS) 2006, 2011, and 2016 were sourced for this study. Women who had a live birth in the last five years of the survey were the unit of analysis for this study. Absolute and relative inequalities in CS utilization were expressed in terms of rate difference and rate ratios, respectively. We used multivariable regression models to assess the CS rate by background sociodemographic characteristics of women.

RESULTS

Age and parity-adjusted CS rates were found to have increased almost threefold (from 3.2%, 95% CI: 2.1-4.3 in 2006 to 10.5%; 95% CI: 8.9-11.9 in 2016) over the decade. In 2016, women from mountain region (3.0%), those from the lowest wealth quintile (2.4%), and those living in Karnali province (2.4%) had CS rate below 5%. Whereas women from the highest wealth quintile (25.1%), with higher education (21.2%), and those delivering in private facilities (37.1%) had CS rate above 15%. Women from the highest wealth quintile (OR-3.3; 95% CI: 1.6-7.0) compared to women from the lowest wealth quintile and those delivered in private/NGO-run facilities (OR-3.6; 95% CI: 2.7-4.9) compared to women delivering in public facilities were more than three times more likely to deliver by CS.

CONCLUSION

To improve maternal and newborn health, strategies need to be revised to address the underuse of CS among poor, those living in mountain region and Province 2, Lumbini province, Karnali province, and Sudhurpaschim province. Simultaneously, there is a pressing need for policies, guidelines, and continuous monitoring of CS rates to reduce overuse among rich women, women with higher education, and those giving childbirth in private facilities.

Socioeconomic inequalities in the use of caesarean section delivery in Ghana: a cross-sectional study using nationally representative data

BACKGROUND

Inappropriate use of Caesarean Section (CS) delivery is partly to blame for Ghana's high maternal mortality rate. However, previous research offered mixed findings about factors associated with CS use. The goal of this study is to examine use of CS in Ghana and the socioeconomic factors associated with it.

METHODS

Data from the nationally representative 2014 Ghana Demographic and Health Survey (GDHS) was used after permission from the Monitoring and Evaluation to Assess and Use Results (MEASURE) Demographic and Health Survey (DHS) program. Univariable and multivariable logistic regression models were fitted to examine the socioeconomic inequalities in CS use. The independent variables included maternal age, marital status, religion, ethnicity, education, place of residence, wealth quintile, and working status. Concentration index (CI) and rate-ratios were computed to ascertain the level of CS inequalities.

RESULTS

Out of the 4294 women, 11.4% had CS delivery. However, the percentage of CS delivery ranged from 5% of women in the poorest quintile to 27.5% of women in the richest qunitle. Significant associations were detected between CS delivery and maternal age, parity, education, and wealth quintile .

CONCLUSIONS

This study revealed that first, even though Ghana has achieved an aggregate CS rate consistent with WHO recommendations, it still suffers from inequities in the use of CS. Second, both underuse of CS among poorer women in Ghana and overuse among rich and educated women are public health concerns that need to be addressed. Third, the results show in spite of Ghana's free maternal care services policies, wealth status of women continues to be strongly and signtificantly associated with CS delivery, indicating that there are indirect health care costs and other reasons preventing poorer women from having access to CS which should be understood better and addressed with appropriate policies.

Regional Outcome Evaluation Program (P.Re.Val.E.): Reduction of inequality in access to effective health care in the Lazio region of Italy (2012-2015)

BACKGROUND

Inequalities in health among groups of various socio-economic status (as measured by education, occupation, and income) constitute one of the main challenges for public health. Since 2006, the Lazio Regional Outcome Evaluation Program (P.Re.Val.E.), presents a set of indicators of hospital performance based on quality standards driven by strong clinical recommendations, and measures the variation in the access to effective health care for different population groups and providers in the Lazio Region. One of the aims of the program was to compare population subgroups in order to promote equity in service provision. Since June 2013, a new management strategy has been put in place that assigned specific goals based on performance assessment to the chief executive officers of the hospitals.

AIM

To evaluate whether, in recent years, there has been a reduction in the differential access to effective health care, among individuals with different educational levels.

METHODS

We enrolled all patients discharged from both public and private hospitals of the Lazio region between 2012 and 2015, living in Lazio region. We analysed the proportion of patients with ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention within 90 minutes (primary PCI), the proportion of patients with hip fracture (HF) who underwent surgery within 2 days, and the proportion of women with primary C-section. We applied multivariate logistic regression models to assess the effect of educational level on health outcomes, adjusting for demographic characteristics and comorbidities that could affect the outcomes. For each year of the study period, we compared adjusted proportions of outcomes for the highest and the lowest level of education by using percentage differences.

RESULTS

In the Lazio region, 44.6% of STEMI patients (N = 3,299) were treated with primary PCI, 54.4% of patients with hip fractures (N = 6,602) underwent surgery within 2 days, and 27.7% of women without a previous C-section (N = 34,718) delivered via C-section, in 2015. The corresponding proportions in 2012 were 27.8%, 31.3% and 31.5%, respectively. By comparing the adjusted proportions in patients with the highest education level (a university degree or higher) to those with the lowest level education level (None/Primary school), a decrease in the percentage difference was observed during the study period. In STEMI and delivery cohorts, the improvement of outcomes involved the least and the most educated patients, respectively, and the difference between the two educational levels was close to zero in 2015, whereas for hip patients, the improvement was more evident among the less educated patients.

CONCLUSIONS

In the Lazio region, we observed a reduction in the differential access to effective heath care by educational level, in different clinical areas. Different factors might explain these results. On top of the public disclosure of outcome data, the management strategy applied in mid-2013 might have driven the overall improvement of the health system for the considered conditions, helping to achieve a fairer access to health.

Association between institutional factors, birth care profile, and cesarean section rates in Santa Catarina

Objectives:

To investigate how institutional factors, represented by the social profile of childbirth care, can relate to cesarean section rates.

Methods:

A cross-sectional study based on data from Sistema de Informações sobre Nascidos Vivos (SINASC) for the state of Santa Catarina collected information for each of the six municipalities with the largest number of births from the six macroregional areas. For those municipalities, all of the establishments that had obstetric facilities were considered. A total of 61.278 births took place over 61 selected maternity services. Cesarean prevalence ratios (PR), both crude and adjusted for confounders, were estimated for each one of the individual variables using robust Cox regression.

Results:

Cesarean births were almost as twice as high in private maternity facilities (89%) when compared to the public ones (45.1%). Giving birth in private hospitals increased by at least 50% the prevalence of caesarean section among primiparae (PR = 1.64), Caucasian (PR = 1.57), women with greater attendance to prenatal care (PR = 1.54), and women having daylight birth (PR = 1.5), when compared with those delivering inside the public sector.

Conclusion:

Differences in cesarean rates in favor of the private system, among women with better social conditions, amongst which it would be expected a lower obstetric risk, have pointed toward differences in obstetric/medical culture permeability and flexibility on medical judgment concerning clinical criteria for cesarean sections.

Potential accessibility scores for hospital care in a province of Japan: GIS-based ecological study of the two-step floating catchment area method and the number of neighborhood hospitals

BACKGROUND

For achieving equity of the accessibility to primary healthcare, measuring potential geographical accessibility is essential. The provider-to-population ratio is the most frequently used measure. However, it is difficult to be used in closer region because it does not take into consideration the people and health services beyond its boundary. In order to overcome this problem, we measured the potential access to hospital, using both distance measures and the enhanced two-step floating catchment area (E2SFCA) method. The aim of this study was to compare the number of hospitals in the neighborhood and the E2SFCA score with regard to the amount and equity for access to hospitals.

METHODS

This descriptive study used publicly available data from 2010. The E2SFCA score and number of neighborhood hospitals were obtained from Tochigi province in Japan using a geographic information system. Dataset of four measures by each census tract was obtained. The measures were E2SFCA score, number of hospitals within the 5 km range, number of hospitals within the 10 km range, and number of hospitals within the 15 km range. Correlation and disparity analyses with the Lorenz curve and Gini coefficient were performed.

RESULTS

The measures were obtained in a smaller area than municipality considering adjacent areas using a geographical approach. The E2SFCA score was 5.3 [3.2-7.3] hospitals/million (median [quantile range]), compared to 5.6 hospitals/million in total for the given district. The median number of hospitals within the 5 km, 10 km, and 15 km ranges were 1, 39, and 47, respectively. There was no hospital within the 5 km range in one third of the blocks. Both the number of hospitals within the 10 km range and those within the 15 km range were well correlated. Regional difference became smaller as the distance to count the number of hospitals increased. The gap between small number of hospitals and the high E2SFCA score indicated the location of community hospital in depopulated areas.

CONCLUSIONS

The E2SFCA method is superior for analyzing spatial access to hospital, because it provides information in the closer sub-regions. Regional differences were hardly seen in access to hospital beyond the 10 km range. Further studies in other regions and countries are needed for precise assessment.

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.

Mode of Delivery Determines Neonatal Pharyngeal Bacterial Composition and Early Intestinal Colonization

OBJECTIVES

Bacterial colonization and succession of the human intestine shape development of immune function and risk for allergic disease, yet these processes remain poorly understood. We investigated the relations between delivery mode, initial bacterial inoculation of the infant oropharynx (OP), and intestinal colonization.

METHODS

We prospectively collected maternal rectal and vaginal swabs, infant OP aspirates, and infant stool from 23 healthy mother/infant pairs delivering by cesarean (CS) or vaginal delivery (VD) in an academic hospital. Bacterial abundance (16S rRNA sequencing) and community similarity between samples were compared by delivery mode. Shotgun DNA metagenomic sequencing of infant stool was performed.

RESULTS

VD infants had higher abundance of Firmicutes (mainly lactobacilli) in OP aspirates whereas CS OP aspirates were enriched in skin bacteria. OP aspirates were more similar to maternal vaginal and rectal microbiomes in VD compared with CS. Bacteroidetes were more abundant through 6 weeks in stool of VD infants. Infant fecal microbiomes in both delivery groups did not resemble maternal rectal or vaginal microbiomes. Differences in fecal bacterial gene potential between CS and VD at 6 weeks clustered in metabolic pathways and were mediated by abundance of Proteobacteria and Bacteroidetes.

CONCLUSIONS

CS infants exhibited different microbiota in the oral inoculum, a chaotic pattern of bacterial succession, and a persistent deficit of intestinal Bacteroidetes. Pioneer OP bacteria transferred from maternal vaginal and intestinal communities were not prominent constituents of the early infant fecal microbiome. Oral inoculation at birth may impact the intestinal microenvironment, thereby modulating early succession of intestinal bacteria.

[Development and validation of a social vulnerability index applied to public policies of the Unified Health System (SUS)]

The article outlines the development and initial validation of a Social Vulnerability Index (SVI) including five social determinants of risk to health and demonstrates its application in the financing of primary care by the Unified Health System (SUS) in the State of Rio Grande do Sul. Municipal indicators of vulnerability relating to poverty and population dispersion were obtained from the 2010 population census of the Brazilian Institute of Geography and Statistics. Both exploratory and confirmatory factor analysis suggests that the five items can constitute a reliable and acceptable measurement scale. The SVI-5 was then generated based on the first main component, measuring municipal inequalities in social vulnerability relating to poverty and population in the territory in Z-scores. The external validity of SVI-5 was examined in relation to health outcomes using DATASUS 2007-2011 data, revealing that infant mortality and hospitalizations for conditions treatable by primary care are greater in more vulnerable municipalities The results suggest that the SVI-5 is a valid measure of inequalities in social vulnerability between municipalities, applicable to socially equitable policies in health.

O parecer do Conselho Federal de Medicina, o incentivo à remuneração ao parto e as taxas de cesariana no Brasil

O estudo buscou investigar como o incentivo à remuneração ao parto, preconizado pelo Conselho Federal de Medicina (CFM) do Brasil, influencia as taxas de cesariana. Foi investigada uma amostra consecutiva de 600 puérperas. A proporção de cesarianas na amostra foi de 59,2%, sendo 92,3% entre as mulheres tendo parto e pré-natal com o mesmo profissional. As taxas de cesariana foram significativamente mais elevadas exatamente naqueles grupos com maior prevalência do mesmo profissional, ou seja, idade mais avançada (RP = 1,65), maior escolaridade (RP = 1,25), pré-natal privado (RP = 1,39) ou por convênio (RP = 1,43), cesariana prévia (RP = 2,78) e admitidas precocemente (RP = 1,93). O entendimento do CFM de que o incentivo ao acompanhamento presencial do trabalho de parto, pago à parte, para o mesmo obstetra que realizou o pré-natal, funcionará como incentivo ao parto normal, está exatamente na contramão de nossos resultados, mostrando que as mulheres atendidas pelo mesmo profissional no pré-natal e parto são exatamente aquelas que apresentam as taxas de cesariana mais elevadas.

The Brazilian preference: cesarean delivery among immigrants in Portugal

Objective

To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals.

Study Design

Women delivered of a singleton birth (n = 8228), recruited from five public level III maternities (April 2005–August 2006) during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908), non-Portuguese European (n = 84), African (n = 77) and Brazilian (n = 159). A Poisson model was used to evaluate the association between country of birth and cesarean section that was measured by adjusted prevalence ratio (PR) and respective 95% confidence intervals (95%CI).

Results

The cesarean section rate varied from 32.1% in non-Portuguese European to 48.4% in Brazilian women (p = 0.008). After adjustment for potential confounders and compared to Portuguese women as a reference, Brazilian women presented significantly higher prevalence of cesarean section (PR = 1.26; 95%CI: 1.08–1.47). The effect was more evident among multiparous women (PR = 1.39; 95%CI: 1.12–1.73) and it was observed when cesarean section was performed either before labor (PR = 1.43; 95%CI: 0.99–2.06) or during labor (PR = 1.30; 95%CI: 1.07–1.58).

Conclusions

The rate of cesarean section was significantly higher among Brazilian women and it was independent of the presence of any known risk factors or usual clinical indications, suggesting that cultural background influences the mode of delivery overcoming the expected standard of care and outcomes in public health services.

Interpersonal processes of care and cesarean delivery in two health care settings

OBJECTIVES

We examined whether interpersonal processes of care (IPC) were associated with cesarean delivery.

METHODS

We performed a cross-sectional study of 1308 postpartum women at Kaiser Permanente Medical Center in Walnut Creek, CA (KP-WC), and San Francisco General Hospital (SFGH) from 2004 to 2006. Using interview and medical record data, logistic regression analyses estimated the odds of cesarean delivery as a function of IPC domains.

RESULTS

After adjustment for demographic and reproductive factors, women at KP-WC who reported higher scores for their provider's "elicitation of patient concerns and responsiveness" were less likely to have delivered by cesarean, whereas women who reported higher scores for "empowerment and self-care" were more likely. At KP-WC, women who reported low English proficiency were less likely to have delivered by cesarean than women who reported high proficiency. At SFGH, none of the IPC measures were significant; however, younger age was associated with a lower risk of cesarean delivery, whereas higher educational attainment was associated with an increased risk.

CONCLUSIONS

To reduce record-high rates of cesarean delivery, more emphasis should be placed on addressing the nonmedical factors associated with operative delivery.

Desigualdades sociais nas complicações da cesariana: uma análise hierarquizada

Com objetivo de investigar associações entre fatores socioeconômicos e complicações da cesariana, uma amostra de 604 puérperas cujos partos ocorreram em duas maternidades no Sul do Brasil foi entrevistada 24 horas pós-parto e na segunda semana do puerpério, por meio de entrevistas hospitalares e domicilio. Regressão de Cox foi aplicada ao modelo hierárquico dos fatores associados ao tipo de parto e às complicações no pós-parto. Complicações foram duas vezes mais frequentes após cesariana, independentemente das condições socioeconômicas. Contudo, a maneira como o parto cesáreo se associou ao risco de complicações mostrou-se mediada pelas circunstâncias socioeconômicas representadas pela categoria do pré-natal e parto, ter ou não o mesmo profissional no pré-natal e parto e ter sua cesariana decidida intraparto. Resultados do estudo evidenciam que complicações pós-cirúrgicas da cesariana têm impacto adverso, principalmente, entre aquelas mulheres vivendo em condições sociais e de saúde menos privilegiadas, as quais, após o parto, retornam para um ambiente de menor suporte, com uma cicatriz abdominal.

Cesarean delivery is associated with an increased risk of obesity in adulthood in a Brazilian birth cohort study

BACKGROUND

Obesity is epidemic worldwide, and increases in cesarean delivery rates have occurred in parallel.

OBJECTIVE

This study aimed to determine whether cesarean delivery is a risk factor for obesity in adulthood in a birth cohort of Brazilian subjects.

DESIGN

We initiated a birth cohort study in Ribeirão Preto, southeastern Brazil, in 1978. A randomly selected sample of 2057 subjects from the original cohort was reassessed in 2002-2004. Type of delivery, birth weight, maternal smoking, and schooling were obtained after birth. The following data from subjects were collected at 23-25 y of age: body mass index (BMI; in kg/m(2)), physical activity, smoking, and income. Obesity was defined as a BMI ≥30. A Poisson multivariable model was performed to determine the association between cesarean delivery and BMI.

RESULTS

The obesity rate in adults born by cesarean delivery was 15.2% and in those born by vaginal delivery was 10.4% (P = 0.002). Adults born by cesarean delivery had an increased risk (prevalence ratio: 1.58; 95% CI: 1.23, 2.02) of obesity at adulthood after adjustments.

CONCLUSION

We hypothesize that increasing rates of cesarean delivery may play a role in the obesity epidemic worldwide.

High prevalence of chronic pelvic pain in women in Ribeirão Preto, Brazil and direct association with abdominal surgery

INTRODUCTION

Chronic pelvic pain is a disease that directly affects the social and professional lives of women.

OBJECTIVE

To estimate the prevalence of this clinical condition and to identify independent factors associated with it in women living in Ribeirão Preto, Brazil.

METHODS

A one-year cross-sectional study was conducted in a population sample of 1,278 women over the age of 1,278 women over the age of 14 years. The target population was predominantly composed of women who are treated by the public health system. The questionnaire was administered by interviewers who were not linked to the city health care programs. The prevalence of the morbidity was estimated. First, we identified the significant variables associated with pelvic pain (p<0.10) and then we attributed values of 0 or 1 to the absence or presence of these variables. Logistic regression analysis was used to identify and estimate the simultaneous impact of the independent variables. The results were expressed by odds ratio and their 95% confidence interval with p<0.05.

RESULTS

The disease was found in 11.5% (147/1,278) of the sample. The independent predictors were dyspareunia, previous abdominal surgery, depression, dysmenorrhea, anxiety, current sexual activity, low back pain, constipation, urinary symptoms, and low educational level.

CONCLUSION

The prevalence of chronic pelvic pain in Ribeirão Preto is high and is associated with conditions that can usually be prevented, controlled, or resolved by improvement of public health policies and public education.
