ABSTRACT

Este estudo objetivou analisar a qualidade do Sistema de Informações sobre Nascidos Vivos em Mato Grosso, estado da região Centro-Oeste do país, por meio do percentual e da tendência de incompletude das variáveis do sistema, no período de 2000 a 2012, segundo as variáveis maternas, da gestação, do parto e do recém-nascido. Trata-se de um estudo ecológico de série temporal. A incompletude das variáveis foi verificada por meio do percentual de dados ignorados e não preenchidos, considerando excelente percentuais inferiores a 1%, boa entre 1% e 2,99%, regular entre 3% e 6,99% e ruim superior a 7%. Para a análise de tendência utilizou-se regressão polinomial. Os resultados mostraram que a qualidade do Sinasc é excelente, pois o percentual de incompletude da maioria das variáveis analisadas foi inferior a 1%. Todavia observou-se tendência crescente dos percentuais de incompletude para raça/cor e idade gestacional o que indica necessidade de monitoramento e controle de qualidade contínuo. [AU]


This study aimed to analyze the quality of the Information System on Live Births (SINASC in Portuguese) in Mato Grosso, state located in the Midwest region of Brazil, by means of the percentage and trend of incompleteness of the system variables in the period from 2000 to 2012, according to maternal, gestational, labor and newborn infants variables. This is an ecological time series study. The incompleteness of the variables was verified by percentage of ignored and unfilled data. Percentages lower than 1% were considered excellent; good, between 1% and 2.99%; regular, between 3% and 6.99%; and poor values, higher than 7%. For the trend analysis, polynomial regression was used. The results showed that the quality of SINASC is excellent, since the percentage of incompleteness of the majority of analyzed variables was less than 1%. However, there was an increasing tendency of incompleteness for race/color and gestational age, indicating a need for continuous quality monitoring and control. [AU]

ABSTRACT

OBJETIVO: Comparar dados pré-natais, dos partos e dos recém-nascidos de Campinas em 2001 e 2005. MÉTODOS: Estudo transversal que analisou 13.656 documentos do Sistema de Informações sobre Nascidos Vivos (Sinasc) de 2005, comparando-as aos resultados de 2001. Analisou-se o local de moradia e parto, idade materna, estado civil, escolaridade, ocupação, paridade, consultas de pré-natal, tipo de parto, duração da gestação e peso ao nascer. Para avaliar a associação entre as variáveis, utilizou-se o teste de qui-quadrado, sendo significante p<0,05. RESULTADOS: Os nascidos nos Distritos de Saúde (DS) com piores índices de condições de vida (ICV) diminuíram em relação a 2001. A taxa de adolescentes passou de 17,7 por cento para 14,7 por cento. Em 2001, 39,4 por cento das mães trabalhavam e, em 2005, 42,9 por cento. Quanto à presença de companheiro, 35,9 e 54,3 por cento não o referiam em 2001 e 2005, respectivamente. A escolaridade passou de 37,8 por cento de mães com até sete anos de estudo para 25,7 por cento, com aumento das que estudaram entre oito e 11 anos e 12 anos ou mais. O comparecimento a mais de seis consultas no pré-natal passou de 74,4 para 86,6 por cento. Houve aumento de cesáreas (54,9 para 60,3 por cento) e de prematuridade (7,1 para 8,9 por cento). Não houve alteração no perfil de peso ao nascimento. CONCLUSÕES: Verificou-se queda da paridade nos DS com piores ICV e no percentual de mães adolescentes. Elevou-se o número de trabalhadoras, mulheres sem companheiro, escolaridade e frequência ao pré-natal.


OBJECTIVE: To compare data related to prenatal care, deliveries and newborns from Campinas, Brazil, in 2001 and 2005. METHODS: This cross-sectional study analyzed 13,656 Live Birth Certificates from 2005, comparing them to of 2001. The analyzed variables were: place of birth and dwelling, maternal age, marital status, schooling, number of births, number of prenatal consultations, mode of delivery, length of pregnancy and birthweight. Association between variables was evaluated by the chi-square test, being significant p<0.05. RESULTS: In 2005, there was a decrease in the number of newborns from Health Districts with worse living conditions in comparison to 2001. The rate of teenage pregnancies varied from 17.7 percent in 2001 to 14.7 percent in 2005. Working mothers were 42.9 percent of the sample in 2005 and 39.4 percent in 2001. In 2005, single mothers were 54.3 percent compared to 35.9 percent in 2001. Mothers with seven or less years of schooling were 37.8 percent in 2001, compared to 25.7 percent in 2005. In 2005, 86.6 percent of mothers had more than six prenatal visits compared to 74.4 percent in 2001. There was an increase in the rates of cesarean section (from 54.9 percent in 2001 to 60.3 percent in 2005) and prematurity (from 7.1 percent in 2001 to 8.9 percent in 2005). No significant changes in birthweight were observed. CONCLUSIONS: This study shows a decrease in the rate of births in the Health Districts with worse conditions of living and in teenage pregnancies. Rates of working mothers, single mothers, years of schooling, number of prenatal consultations increased.

ABSTRACT

OBJETIVO: Estimar a prevalência de defeitos congênitos (DC) em uma coorte de nascidos vivos (NV) vinculando-se os bancos de dados do Sistema de Informação de Mortalidade (SIM) e do Sistema de Informação sobre Nascidos Vivos (SINASC). MÉTODOS: Estudo descritivo para avaliar as declarações de nascido vivo como fonte de informação sobre DC. A população de estudo é uma coorte de NV hospitalares do 1º semestre de 2006 de mães residentes e ocorridos no Município de São Paulo no período de 01/01/2006 a 30/06/2006, obtida por meio da vinculação dos bancos de dados das declarações de nascido vivo e óbitos neonatais provenientes da coorte. RESULTADOS: Os DC mais prevalentes segundo o SINASC foram: malformações congênitas (MC) e deformidades do aparelho osteomuscular (44,7 por cento), MC do sistema nervoso (10,0 por cento) e anomalias cromossômicas (8,6 por cento). Após a vinculação, houve uma recuperação de 80,0 por cento de indivíduos portadores de DC do aparelho circulatório, 73,3 por cento de DC do aparelho respiratório e 62,5 por cento de DC do aparelho digestivo. O SINASC fez 55,2 por cento das notificações de DC e o SIM notificou 44,8 por cento, mostrando-se importante para a recuperação de informações de DC. Segundo o SINASC, a taxa de prevalência de DC na coorte foi de 75,4 por cento00 NV; com os dados vinculados com o SIM, essa taxa passou para 86,2 por cento00 NV. CONCLUSÕES: A complementação de dados obtida pela vinculação SIM/SINASC fornece um perfil mais real da prevalência de DC do que aquele registrado pelo SINASC, que identifica os DC mais visíveis, enquanto o SIM identifica os mais letais, mostrando a importância do uso conjunto das duas fontes de dados.


OBJECTIVE: To obtain the prevalence of birth defects in a live birth cohort, linking the live birth information system (SINASC) and the mortality information system (SIM) databases. METHODS: Descriptive study to assess linked databases of hospital live births (LB) and neonatal deaths of resident mothers that occurred in the city of São Paulo, between January 1st, 2006 and June 30th, 2006. RESULTS:According to the SINASC, the most prevalent birth defects (BD) were: BD and musculoskeletal system deformity (44.7 percent), nervous system BD (10.0 percent) and chromosomal anomalies (8.6 percent). There was 80.0 percent of recovery of circulatory system BD, 73.3 percent of respiratory system BD and 62.5 percent of digestive system BD in the linked database. Linked data set identified BD in 640 live births; the SINASC accounted for 55.2 percent of notifications and the SIM for 44.8 percent. The prevalence rate of BD based on SINASC data was 75.4 percent00 LB. This rate showed an increase of 14.3 percent when obtained from the linked dataset (86.2 percent00 LB). CONCLUSION: Linkage of the live birth (SINASC) and mortality systems (SIM) provides a more real BD profile. BDs notified by the SINASC were more visible at birth, while the SIM notified more fatal BD, showing the importance of utilizing both data sources.

ABSTRACT

OBJETIVO: Estimar a prevalência de defeitos de fechamento do tubo neural no Vale do Paraíba paulista e identificar possíveis fatores maternos e neonatais associados a tais defeitos. MÉTODOS: Realizou-se um estudo transversal com dados secundários obtidos na Secretaria Estadual da Saúde referentes aos nascimentos ocorridos em 2004 no Vale do Paraíba paulista, que compreende 35 municípios e conta com população de 2 milhões de habitantes. Anencefalia, encefalocele e espina bífida (mielocele e mielomeningocele) foram considerados defeitos de fechamento do tubo neural. As variáveis maternas foram: idade, escolaridade, cor da pele, número de consultas no pré-natal, número de filhos vivos e relato de óbito fetal prévio. As variáveis relativas ao recém-nascido foram: peso, idade gestacional e escore de Apgar. Realizou-se comparação das médias por meio do teste t de Student e obtiveram-se os valores das razões de chance com intervalos de confiança de 95%. RESULTADOS: Foram analisados 33.653 nascidos vivos. Trinta e oito recém-nascidos com o defeito foram encontrados (1,13/1.000 nascidos vivos), sendo 23 casos de espina bífida. Houve associação com baixo peso ao nascimento, prematuridade e menores escores de Apgar de cinco minutos. CONCLUSÕES: A prevalência desta anomalia foi inferior à de outros estudos nacionais e sua presença esteve associada ao baixo peso, à prematuridade e à baixa vitalidade ao nascer.


OBJECTIVE: To estimate the prevalence of neural tube defects in Vale do Paraíba, São Paulo, Brazil, and to identify possible maternal and neonatal variables associated with these defects. METHODS: This cross-sectional study used secondary records of the Health Department of São Paulo State related live births during 2004 in Vale do Paraíba, São Paulo, Brazil. This region has 35 cities and 2 million inhabitants. Anencephaly, encephalocele and spina bifida (myelocele and myelomeningocele) were considered as neural tube defects. The following maternal variables were analyzed: age, educational level, race, number of born alive and stillborn infants and prenatal visits. Neonatal variables were: birth weight, gestational age and Apgar score. Numerical variables were compared by Student t test, and Odds Ratio values were obtained with the 95%confidence interval. RESULTS: The analysis was performed based on 33,653 records of born alive infants. Twenty-three infants with spina bifida were identified, with an estimated prevalence of 1.13 cases for each 1,000 live births. The presence of neural tube defects was associated to low birth weight, prematurity and low Apgar score. CONCLUSIONS: The estimated prevalence of neural tube defects in this region of São Paulo was lower than others reported in previous Brazilian studies. These defects were associated with low birth weight, prematurity and respiratory depression at birth.

ABSTRACT

OBJECTIVE: Preterm birth is one of the leading causes of infant death and a major contributor to early childhood morbidity. It has been recognized that numerous factors are responsible for the development of preterm delivery. Among these factors, environmental influences have been demonstrated in many studies. The purpose of this study was to analyze the regional variations of preterm birth rates and to reveal the association between environmental influences and preterm birth. METHODS: Based on the 2003 birth certificate data from National Statistical Office, we analyzed 475,680 singleton births with certain gestational age at delivery of seven metropolitan cities and nine provinces in Korea. Multiple logistic regression analysis was used to examine the relationship between preterm birth and regional differences, adjusting for other risk factors such as maternal age, sex of infants, order of the babies and mother's education. RESULTS: The rate of preterm delivery was 3.8 percent. The highest preterm birth rate was observed in Daegu metropolitan city (4.2%), and the lowest in Jeonbuk province (3.2%). Risk of preterm birth was higher in mothers with younger ( or =30 years) ages, with lower educational levels, and in male infants. There was a significant increase in the risk of preterm birth in Daegu metropolitan city (odds ratio (OR) 1.32, 95% confidence interval (CI), 1.19~1.47), Gangwon province (OR 1.27, 95% CI, 1.13~1.43), Gyeongbuk province (OR 1.26, 95% CI, 1.14~1.40), Jeonnam province (OR 1.22, 95% CI, 1.09~1.37), Busan metropolitan city (OR 1.21, 95% CI, 1.09~1.34), Ulsan metropolitan city (OR 1.19, 95% CI, 1.05~1.36), and Gyeonggi province (OR 1.15, 95% CI, 1.05~1.26) as compared with the incidence of preterm birth in Jeonbuk province. CONCLUSION: Regional variations of preterm birth rate was observed among metropolitan cities and provinces in Korea. Further larger scale studies are necessary to determine more specific factors associated with these differences.

ABSTRACT

OBJECTIVE: To determine whether paternal age is associated with the risk of preterm birth. METHODS: Data were obtained from the 2003 birth certificates registry of 214,413 singleton infants born to women aged 25~29 years in Korea (Korea National Statistical Office). Odds ratios and 95% confidence intervals were calculated from multivariate logistic regression analyses to investigate the associations between paternal age and preterm delivery. RESULTS: The incidence of preterm birth showed a significant difference among the different paternal age groups (p0.05), 1.08 for age 25~29 years (p or =40 years (p<0.01) groups. CONCLUSION: Paternal age is a risk factor for preterm birth and advanced paternal age increases the risk of preterm birth.

ABSTRACT

Este trabalho tem por objetivo avaliar a associação entre as variáveis presentes na Declaração de Nascido Vivo do Ministério da Saúde (DN) e o baixo peso ao nascer. É um estudo transversal onde foram analisadas 2.018 DN referentes a nascimentos vivos não gemelares de 1998, ocorridos em Guaratinguetá, SP. A análise estatística baseou-se nas técnicas do Qui quadrado e Razão de Prevalência. Foi feita análise estratificada para testar interação e confusão entre variáveis. Foram construídos intervalos de 95% de confiança e adotado nível de significância de 5% (α = 0,05). Observou-se associação estatisticamente significativa (p<0,05) entre baixo peso ao nascer e idades maternas menor que 19 anos e maior que 35 anos, mães com menor escolaridade, menor número de consultas no pré-natal e gravidez anterior com desfecho desfavorável, isto é, com relato de aborto ou natimorto. Conclui-se que a DN é um instrumento útil e de fácil acesso para avaliar a atenção dedicada à mãe e ao recém-nascido. Sugere-se a inclusão de novos campos com outras informações sociais e clínicas da mãe.


The aim of this research was to detect associations between low birth weight and some variables that are present in the Live Birth Certificate of the Brazilian Ministry of Health. A cross-sectional study was performed using a set of 2,018 records of single live births which occurred during 1998, in Guaratinguetá, a midsize city of the State of São Paulo, Brazil. Analyses included the calculation of prevalence ratios and χ2 test to detect statistical associations. Confidence intervals for the prevalence ratios were constructed. Stratified analyses was performed to test for interaction and to control for confounding. Statistically significant associations (p<0.05) were detected between low birth weight and maternal age (less than 19 and greater than 35 years of age), low educational level, low number of pre-natal visits and presence of previous pregnancy with unfavorable outcomes (abortion or stillbirth). It was possible to conclude that the Live Birth Certificate is a useful and readily available instrument to evaluate maternal and newborn care. Suggestions are made to inckude fields in the form to collect data about maternal social and medical conditions.

ABSTRACT

OBJECTIVE: Multiple birth implicates the important health and social problems such as preterm birth, low birth weight, high perinatal mortality, and increased medical cost. This study was performed to investigate the multiple birth rate in Korea using the birth certificate data. METHODS: Retrospective review and analysis of data from Korean birth certificate in 1996. RESULTS: Multiple birth rate was 1.4% of total births(683,043 cases). Mean birth weight was 3.29+/-0.47kg for singleton birth and 2.57+/-0.58kg for multiple birth. Mean gestational age was 39.56+/-1.32 weeks for singleton birth and 37.47+/-2.41 weeks for multiple birth. Rate of low birth weight (< 2.5kg) was 14 times higher for multiple birth compared with that of singleton birth, and rate of preterm birth(< 37 weeks) was 10 times higher. Multiple logistic regression analysis was performed to examine the relationship between multiple birth and selected variables including maternal age, job and birth order. As the odds ratio(OR) was 2.47(95% CI: 2.34 - 2.59, p<0.001) for the second birth, and 5.31(95% CI: 4.99 - 5.65, p<0.001) for the third and over birth compared with the first birth, there was a significant correlation between multiple birth and birth order. CONCLUSIONS: Based on the birth certificate data in 1996, the incidence of twin and higher order multiple birth was 1.7%, and a significant correlation between multiple birth and birth order was revealed. Further studies are necessary to elucidate the etiology and prognosis of multiple birth and the developmental problems from birth to adolescence.
