Nascer no Brasil: the presence of a companion favors the use of best practices in delivery care in the South region of Brazil

OBJECTIVE: To analyze if the presence of a companion favors the use of best practices in the delivery care in the South region of Brazil. METHODS: This is a cross-sectional analysis of the longitudinal study Nascer no Brasil. We analyzed data from 2,070 women from the South region of Brazil who went into labor. The data were collected between February and August 2011, by interviews and medical records. We performed a bivariate and multivariate analysis, calculating the crude and adjusted prevalence ratios using Poisson regression with robust variance estimation. The level of significance adopted was 5%. RESULTS: Most women had a companion during labor (51.7%), but few remained during delivery (39.4%) or cesarean section (34.8%). Less than half of the women had access to several recommended practices, while non-recommended practices continue to be performed. In the model adjusted for age, education level, source of payment for the delivery, parity, and score of the Brazilian Association of Market Research Institutes, the presence of a companion was statistically associated with a greater supply of liquids and food (aPR = 1.34), dietary prescription (aPR = 1.34), use of non-pharmacological methods for pain relief (aPR = 1.37), amniotomy (aPR = 1.10), epidural or spinal analgesia (aPR = 1.84), adoption of non-lithotomy position in the delivery (aPR = 1.77), stay in the same room during labor, delivery, and postpartum (aPR = 1.62), skin-to-skin contact in the delivery (aPR = 1.81) and cesarean section (PR = 2.43), as well as reduced use of the Kristeller maneuver (aPR = 0.67), trichotomy (aPR = 0.59), and enema (aPR = 0.49). CONCLUSIONS: In the South region of Brazil, most women do not have access to the best practices in addition to undergoing several unnecessary interventions. The presence of a companion is associated with several beneficial practices and the reduction in some interventions, although other interventions are not impacted.OBJETIVO: Analisar se a presença do acompanhante favorece a aplicação das boas práticas na atenção ao parto na região Sul do Brasil. MÉTODOS: Análise transversal do estudo longitudinal Nascer no Brasil. Foram analisados dados de 2.070 mulheres da região Sul que entraram em trabalho de parto. Os dados foram coletados entre fevereiro e agosto de 2011, por meio de entrevista e prontuário. Realizou-se análise bivariada e multivariada, calculando-se razões de prevalência brutas e ajustadas por regressão de Poisson com estimação de variância robusta. Adotou-se nível de significância de 5%. RESULTADOS: A maioria das mulheres teve o acompanhante durante o trabalho de parto (51,7%), mas poucas permaneceram com ele no parto (39,4%) ou na cesariana (34,8%). Menos da metade das mulheres teve acesso às várias práticas recomendadas, enquanto práticas não recomendadas continuam sendo realizadas. No modelo ajustado por idade, escolaridade, fonte de pagamento do parto, paridade e escore da Associação Brasileira de Institutos de Pesquisa de Mercado, a presença do acompanhante esteve estatisticamente associada à maior oferta de líquidos/alimentos (RPa = 1,34), prescrição de dieta (RPa = 1,34), uso de métodos não farmacológicos para alívio da dor (RPa = 1,37), amniotomia (RPa = 1,10), analgesia peridural ou ráqui (RPa = 1,84), adoção de posição não litotômica no parto (RPa = 1,77), permanência na mesma sala durante o trabalho de parto, parto e pós-parto (RPa = 1,62), contato pele a pele no parto (RPa = 1,81) e na cesariana (RP = 2,43), bem como redução da manobra de Kristeller (RPa = 0,67), tricotomia (RPa = 0,59) e enema (RPa = 0,49). CONCLUSÕES: Na região Sul do Brasil, além de sofrer várias intervenções desnecessárias, a maioria das mulheres não têm acesso às boas práticas. A presença do acompanhante está associada a diversas práticas benéficas e à redução de algumas intervenções, embora outras não sofram impacto

Fatores associados a taxas de cesárea em hospital universitário

OBJECTIVE: To assess factors associated to cesarean section. METHODS: A cross-sectional study was conducted in a university hospital in Florianópolis, Southern Brazil, from 2001 to 2005. Socioeconomic, reproductive, obstetric and institutional information were collected. Data from 7,249 deliveries was obtained from medical records and admission, delivery and post-delivery records. Cox regression was used in the analysis to estimate cesarean prevalence ratios in the categories of variables studied. RESULTS: Cesarean rates increased from 27.5% to 36.5% during the period studied and they were higher than those associated with medical indications. After adjustment for confounders cesarean rates were positively associated with previous cesarean section (PR=2.65, 95% CI: 2.31;3.05), non-cephalic presentation (PR=2.23, 95%CI: 1.69;2.95), oxytocin use (PR=1.77, 95%CI: 1.43;2.19), dilatation at admission (PR=2.74, 95%CI: 2.18;3.44), and obstetrician profile (>;35% of cesarean sections) (PR=1.82, 95%CI: 1.36;2.42). CONCLUSIONS: The factors associated with cesarean section indicate the need of interventions focusing on women and their reproductive experience and changes in obstetrician practice as well.OBJETIVO: Analizar factores asociados a la realización del parto cesariano. MÉTODOS: Estudio transversal realizado en hospital universitario de Florianópolis, Sur de Brasil, de 2001 a 2005. Fueron analizados factores socioeconómicos, de experiencias reproductivas, institucionales y relacionados con la práctica obstétrica. Las informaciones relativas a 7.249 partos fueron obtenidas a partir de prontuarios clínicos y registros de admisión, parto y post-parto. Fue utilizada la regresión de Cox en el análisis para estimar razones de prevalencia de cesárea en las categorías de las variables de interés. RESULTADOS: Las tasas de cesárea aumentaron de 27,5% a 36,5% en el período y estuvieron encima de aquellas debidas a indicaciones médicas. Posterior al ajuste para confundimento, las tasas de cesárea se mostraron positivamente asociadas con cesárea previa (RP=2,65; IC 95%: 2,31; 3,05), presentación no cefálica (RP=2,23; IC 95%: 1,69; 2,95), uso de ocitocina (RP=1,77; IC 95%: 1,43; 2,19), dilatación al ser admitida (RP=2,74; IC 95%: 2,18; 3,44), y obstetra con tasa de cesárea superior a 35% (RP=1,82; IC 95%: 1,36; 2,42). CONCLUSIONES: Los factores asociados a mayor probabilidad de cesárea mostraron la importancia de intervenciones direccionadas a la mujer y su experiencia reproductiva, así como cambios en la práctica obstétrica.OBJETIVO: Analisar fatores associados à realização do parto cesariano.

Temporal analysis of the relationship between leptospirosis, rainfall levels and seasonality, Santa Catarina, Brazil, 2005-2015

The objective of the study is to analyze the temporal trend of leptospirosis incidence, according to rainfall levels in Santa Catarina, according to seasonality, from 2005 to 2015. This is an ecological study of time series, with date of leptospirosis, rainfall levels and population. The incidence rates of leptospirosis, relative excess of incidence, Pearson’s correlation coefficient (r) and an angular coefficient (β) were analyzed from the linear regression adjustment, with a 5% significance level. Distribution of leptospirosis cases, rainfall levels and cases reason/rainfall levels, stratified by month of occurrence were presented. There were 5,274 cases of leptospirosis, with the monthly average being 439 cases, ranging from 211 in September to 770 in January. The mean rate of leptospirosis was 7.03 per 100,000 habitants. The average rainfall level was 158.68 mm, with the lowest levels occurring in August, average of 124.9 mm, and the highest in January average of 213.20 mm. The positive correlation between leptospirosis rates and rainfall levels, during the period from January to December (r = 0.68, p = 0.023), indicates a positive temporal association between the amount of rainfall and the cases of the disease. The disease occurred all year round and presented a distinct seasonality from October to March

Social inequalities in cesarean section rates in primiparae, Southern Brazil

OBJECTIVE: To investigate the effect of social inequalities in cesarean section rates among primiparae having single pregnancy and delivering in maternity hospitals. METHODS: The study was carried out in Southern Brazil in 1996, 1998 and 2000. Data from the Live Birth National Information System were used to estimate annual rates and crude and adjusted odds ratios (OR) of cesarean sections according to social conditions (maternal age and education, newborn skin color/ethnicity and macro-regions), duration of pregnancy, and number of prenatal visits. RESULTS: The overall cesarean section rate was 45%, and above 37% in all macro-regions. Increased rates were seen among native and black mothers, aged 30 years or more, living in metropolitan, river valley and mountain macro-regions and having attended to more than six prenatal visits. Crude and adjusted OR show that cesarean rates were negatively associated with all categories of skin color/ethnicity when compared to white newborns, particularly those of native Brazilian (ORadj=0.43; 95% CI: 0.31-0.59), and they were positively associated with higher maternal education (ORadj=3.52; 95% CI: 3.11-3.99), older age (ORadj=6.87; 95% CI: 5.90-8.00) and greater number of prenatal visits (ORadj=2.16; 95% CI: 1.99-2.35). The effects of age and education were partly mediated by the greater number of prenatal visits among higher educated older women. The OR varied among macro-regions but were greater for the wealthier mountain region. CONCLUSIONS: High rates of cesarean section rates in Southern Brazil are a public health concern. They are associated with social, economic and cultural factors which can lead to misuse of medical technology during labor and delivery.OBJETIVO: Investigar o efeito das desigualdades sociais nas taxas de cesariana em primíparas, com gravidez única e parto hospitalar. MÉTODOS: Estudo realizado no Estado do Rio Grande do Sul em 1996, 1998 e 2000. Foram utilizados dados do Sistema de Informação de Nascidos Vivos no cálculo das taxas anuais e das razões de chance de cesariana (RC) brutas e ajustadas para condições sociais (escolaridade e idade maternas, etnia/cor da pele e macro-regional de saúde), duração da gestação e número de consultas pré-natal. RESULTADOS: A taxa de cesarianas foi de 45%, e acima de 37% para todas as macro-regionais. As taxas aumentaram entre: mulheres de etnia indígena e negra, mulheres com mais de 30 anos, residentes nas macro-regiões Metropolitana, Vales e Serra, e com mais de seis consultas no pré-natal. Razões brutas e ajustadas indicaram taxas negativamente associadas para todas as categorias de etnia/cor, quando comparadas à cor branca da pele do recém-nascido, em especial para etnia indígena (RCaj=0,43; IC 95%: 0,31-0,59), positivamente associadas à escolaridade (RCaj=3,52; IC 95%: 3,11-3,99) e idade maternas mais elevadas (RCaj=6,87; IC 95%: 5,90-8,00), e maior número de consultas pré-natal (RCaj=2,16; IC 95%: 1,99-2,35). Os efeitos de idade e escolaridade mostraram estar parcialmente mediados pelo maior número de consultas pré-natal nas mulheres com idade e escolaridade mais elevadas. As taxas variaram entre as macro-regionais, sendo maiores na região da Serra, economicamente mais rica. CONCLUSÕES: Altas taxas de cesariana no sul do Brasil constituem problema de saúde pública e estão associadas a fatores sociais, econômicos e culturais, os quais podem levar ao mau-uso da tecnologia médica na atenção ao parto

Temporal analysis of leptospirosis incidence according to rainfall levels

The aim of this study was to analyze the temporal trend of leptospirosis incidence according to rainfall levels in Santa Catarina State between 2005 and 2015. This is an ecological time-series study involving data on leptospirosis incidence and rainfall indexes in Santa Catarina State Health Regions. The distribution of leptospirosis, rainfall indexes, and cases/rainfall ratios, according to seasonality and stratified by Health Regions, were evaluated. There were 5,274 cases, with an average rate of 7.03 cases/100,000 inhabitants per year, varying from 24 to 1,458 cases (Serra Catarinense and Northeast regions, respectively) in Santa Catarina, revealing an increase in the rates of 0.70 cases/100,000 inhabitants in Serra Catarinense and 13.99 cases/100,000 inhabitants in the Northeast. Four regions (Foz do Rio Itajaí, Médio Vale do Itajaí, Grande Florianópolis and Northeast) were responsible for 71.8% of the cases, particularly in the Northeast region (38.5%). The five regions with the highest rates presented greater risk of leptospirosis (RR > 1), ranging from 10.9 to 19.9 more new cases of the disease. The average rainfall volume for Santa Catarina State was 158.69 mm, ranging from 136.44 mm in Laguna to 186.81 mm in the Northeast. The five regions contributed with 32.8% of the rainfall index accumulated in the period. In conclusion, leptospirosis occurred all around Santa Catarina State, differing its temporal trend according to the Health Regions.
