BackgroundCaesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction.MethodsNationwide hospital-based cohort study of postnatal women and their offspring with follow-up at 45 to 60 days after birth. The sample was stratified by geographic macro-region, type of the municipality and by type of hospital governance. The number of postnatal women sampled was 23,940, distributed in 191 municipalities throughout Brazil. Two electronic questionnaires were applied to the postnatal women, one baseline face-to-face and one follow-up telephone interview. Two other questionnaires were filled with information on patients’ medical records and to assess hospital facilities. The primary outcome was the percentage of Caesarean sections (total, elective and according to Robson’s groups). Secondary outcomes were: post-partum pain; breastfeeding initiation; severe/near miss maternal morbidity; reasons for maternal mortality; prematurity; low birth weight; use of oxygen use after birth and mechanical ventilation; admission to neonatal ICU; stillbirths; neonatal mortality; readmission in hospital; use of surfactant; asphyxia; severe/near miss neonatal morbidity. The association between variables were investigated using bivariate, stratified and multivariate model analyses. Statistical tests were applied according to data distribution and homogeneity of variances of groups to be compared. All analyses were taken into consideration for the complex sample design.DiscussionThis study, for the first time, depicts a national panorama of labour and birth outcomes in Brazil. Regardless of the socioeconomic level, demand for Caesarean section appears to be based on the belief that the quality of obstetric care is closely associated to the technology used in labour and birth. Within this context, it was justified to conduct a nationwide study to understand the reasons that lead pregnant women to submit to Caesarean sections and to verify any association between this type of birth and it’s consequences on postnatal health.

Abstract

Trajetória das mulheres na definição pelo parto cesáreo: estudo de caso em duas unidades do sistema de saúde suplementar do estado do Rio de Janeiro

A assistência nutricional tem grande relevância no pré-natal e as equipes de saúde da família têm papel importante na ampliação da cobertura do cuidado pré-natal. Desta forma, este estudo teve o objetivo de avaliar o processo da assistência nutricional no pré-natal em sete unidades de saúde da família do Município do Rio de Janeiro. Um estudo transversal foi conduzido em 2008 e foram entrevistadas 230 gestantes e obtidas as cópias dos cartões de pré-natal. Avaliou-se a conformidade do processo com critérios e normas pré-determinados pelo Ministério da Saúde. Os resultados indicaram que a aferição e o registro no cartão de pré-natal da pressão arterial e do peso, bem como a prescrição de suplementos e exames de sangue estão estabelecidos como rotinas do pré-natal. Também indicaram que, no cartão, há sub-registro de: estatura, peso inicial, edema, IMC por semana gestacional e resultados de exames. Verificou-se a carência de orientações específicas sobre utilização do sulfato ferroso, consumo de alimentos e ganho de peso. Os resultados revelaram uma grande necessidade de assistência nutricional e deficiências no seu processo, o que aponta para a importância do treinamento da equipe mínima e da implantação dos Núcleos de Apoio à Saúde da Família.
