Abstract
Objective: The objective of this research was to study the role of music listening by mothers during a cesarean section and the postpartum period to achieve exclusive breastfeeding in the first 6 months. Methods and Study Design: This was a prospective, observational, randomized controlled trial study. A total of 185 singleton pregnant women, in at least 37 weeks of gestation, who were appointed for elective cesarean sections, were recruited. They were randomized into three groups, including pregnant women who did not listen to music (Group 1), listened to music during cesarean section (Group 2), and listened to music during cesarean section and the postpartum room for the first 2 days (Group 3). The breastfeeding results of all three groups were followed up at 7 days, 14 days, and then at months 1, 2, 3, and 6. Results: Success in exclusive breastfeeding among Groups 1, 2, and 3 and Groups 1 and 2 + 3 was not different in every lactating period (7 days-6 months). From subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Mothers who listened to music and had an income of <20,000 baht, an educational level lower than university, planned the pregnancy, had their first pregnancy, and stayed in a private ward had more successful exclusive breastfeeding in a 6-month period than those mothers who did not listen to music, and the difference was statistically significant. Conclusions: Music listening by mothers during a cesarean section and in the postpartum ward did not enhance exclusive breastfeeding during the first 6 months of the postpartum period. However, from subgroup analysis, mothers who listened to music in a private ward had more success in exclusive breastfeeding than those in a common ward. Thai Clinical Trials Registry number was TCTR20180712001.

Abstract
The prevalence of preterm births has shown a growing trend in many countries, including developed ones. Studies in Brazil have shown that the Information System on Live Births (SINASC, in Portuguese), until 2010, underestimated the prevalence of preterm births, when compared with studies based on primary data. Starting in 2011, gestational age at birth has been calculated in SINASC according to the last menstrual period (LMP), when available. This study sought to evaluate the accuracy of the gestational age assessment using LMP, compared with two other estimates, and correlate it with birth weight. This is a population study with data from SINASC available from Brazilian Health Informatics Department between 2011 and 2015. Definitions of preterm birth, low birth weight and birth asphyxia were taken from the literature. Adequacy of birth weigh to gestational age was calculated based on Fenton and Intergrowth-21 curves. We compared weight means according to the presence or lack of preterm birth. gestational age assessment was based on LMP in 58.5% and 41.5% used another method. We found that the preterm proportion was 12% in the LMP group and 8.4% in the other method group, while low birth weight was 6.5% and 8.4%, respectively. Mean weight of preterm infants was higher in the LMP group. Use of LMP as a gestational age estimator overestimated the proportion of weight equal to or higher than 2,500g among preterm infants, which does not seem compatible with the expected distribution for this group. LMP favored "correction" of prematurity for the parameters that are comparable to those of primary data studies, though the distortions we found between gestational age and birth weigh may indicate that there are still problems with this estimator.

Abstract
Situations including premature infants, or those in which there is a rejection to breastfeeding, require the use infant formulas for total or partial replacement of human milk. The objective of this study was to determine the lipid content and to identify the lipid profile of infant formulas. Samples were collected from ten different infant formulas, used as a substitute for breast milk at the Maternal and Child Hospital of Brasilia. The human milk sample consisted of a pool of samples from 10 mature milk donors at the milk bank of the University Hospital of Brasilia. The lipid content and lipid profile of the different infant formulas and human milk were analyzed. The experiment was conducted in a randomized block design, with eleven treatments and three replicates, in triplicate. The data obtained in this study indicated significant differences between infant formulas and human milk, and among the infant formulas analyzed in relation to the percentage of total lipids and the fatty acid profile, except for the fractions of linoleic acid and linolenic acid. Regarding the percentage of polyunsaturated fatty acids in relation to the total unsaturated fatty acids, only the Soy Protein Isolate-based Infant Formula (SPIIF) and Whey Protein Extensively Hydrolyzed Infant Formula (WPEHIF) resembled human milk. It was concluded that despite the observed differences, the use of infant formulas is a viable strategy for the development of infants subjected or not to specific physiological conditions.

Abstract
OBJECTIVE: To investigate the effect of air pollution on birth weight in a medium-sized town
in the State of São Paulo, Southeast Brazil. METHODS: Cross-sectional study using data from live births of mothers residing in São José
dos Campos from 2005 to 2009. Data was obtained from the Department of Information
and Computing of the Brazilian Unified Health System. Air pollutant data
(PM10, SO2, and O3) and daily averages of
their concentrations were obtained from the Environmental Sanitation &
Technology Company. Statistical analysis was performed by linear and logistic
regressions using the Excel and STATA v.7 software programs. RESULTS: Maternal exposure to air pollutants was not associated with low birth weight,
with the exception of exposure to SO2 within the last month of
pregnancy (OR=1.25; 95% CI=1.00-1.56). Maternal exposure to PM10 and
SO2 during the last month of pregnancy led to lower weight at birth
(0.28g and 3.15g, respectively) for each 1mg/m3 increase in the concentration of these pollutants, but without
statistical significance. CONCLUSIONS: This study failed to identify a statistically significant association between the
levels of air pollutants and birth weight, with the exception of exposure to
SO2 within the last month of pregnancy.

Abstract
OBJECTIVE To analyze if dietary patterns during the third gestational trimester are associated with birth weight. METHODS Longitudinal study conducted in the cities of Petropolis and Queimados, Rio de Janeiro (RJ), Southeastern Brazil, between 2007 and 2008. We analyzed data from the first and second follow-up wave of a prospective cohort. Food consumption of 1,298 pregnant women was assessed using a semi-quantitative questionnaire about food frequency. Dietary patterns were obtained by exploratory factor analysis, using the Varimax rotation method. We also applied the multivariate linear regression model to estimate the association between food consumption patterns and birth weight. RESULTS Four patterns of consumption – which explain 36.4% of the variability – were identified and divided as follows: (1) prudent pattern (milk, yogurt, cheese, fruit and fresh-fruit juice, cracker, and chicken/beef/fish/liver), which explained 14.9% of the consumption; (2) traditional pattern, consisting of beans, rice, vegetables, breads, butter/margarine and sugar, which explained 8.8% of the variation in consumption; (3) Western pattern (potato/cassava/yams, macaroni, flour/farofa/grits, pizza/hamburger/deep fried pastries, soft drinks/cool drinks and pork/sausages/egg), which accounts for 6.9% of the variance; and (4) snack pattern (sandwich cookie, salty snacks, chocolate, and chocolate drink mix), which explains 5.7% of the consumption variability. The snack dietary pattern was positively associated with birth weight (β = 56.64; p = 0.04) in pregnant adolescents. CONCLUSIONS For pregnant adolescents, the greater the adherence to snack pattern during pregnancy, the greater the baby’s birth weight.

Abstract
OBJECTIVE To evaluate the pulmonary function in high-risk pregnant women. METHODS This was a prospective cross-sectional study on 60 pregnant women, of whom 30 were high-risk and 30 were low-risk cases, with gestational age ≥28 weeks. For the high-risk group, preeclampsia and/or gestational diabetes were the conditions taken into consideration. To evaluate pulmonary function, the following parameters were assessed: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), Tiffeneau index (FVC/FEV1) and forced expiratory flow (FEF25-75%). Fisher's exact test or the chi-square test was used to analyze the variables. RESULTS There were no statistical differences in the pulmonary function parameters according to gestational age (p > 0.05). Similarly, there were no statistical differences in the pulmonary function tests for the variables of smoking habit, birth weight, Apgar index, duration of gestation, childbirth type and need for the newborn to go to the intensive care unit (p > 0.05). For the pregnant women with preeclampsia and gestational diabetes, only FEF25-75% presented statistical significance (p = 0.01 and 0.034, respectively). CONCLUSION In high-risk pregnant women, pulmonary function suffered alterations characterized by limitations regarding airflow through the airways, although without repercussions on gestational outcome.

Abstract
O presente estudo analisou fatores relacionados ao peso ao nascer em um hospital maternidade do município do Rio de Janeiro. Trata-se de estudo seccional, descritivo, conduzido no Hospital Maternidade Herculano Pinheiro (HMHP), Rio de Janeiro, entre dezembro de 2008 e fevereiro de 2009, com puérperas entre 20 e 34 anos. Foram aplicados os testes de Qui-quadrado, t de student e modelo de regressão logística. Dos recém-nascidos, 14,6% tinham baixo peso ao nascer (inferior à 2500g). Encontrou-se correlação negativa entre o peso ao nascer e o hábito de fumar da mãe. As variáveis peso pré-gestacional, índice de massa corporal pré-gestacional materno e número de consultas no pré-natal apresentaram associação positiva com o peso ao nascer. A análise múltipla indicou a idade materna como fator de risco para o baixo peso ao nascer. Conclui-se que a situação sobre o estado civil, onde este se apresentou como uma variável importante, assim como o número de consultas pré-natal que na análise do grupo não apresentou significado estatístico, merece maior investigação com outros estudos.

Abstract
Low birth weight is associated with increased risk of dying in the first year of life. This study was motivated by recent changes in the determination of birth weight patterns with the advent of the perinatal epidemiological transition. We analyzed data from the Brazilian National Survey of Demographic and Health of Children and Women including only children < 24 months. Prevalence of low birth weight in Brazil was 6.1%. Risk factors included female gender, residence in the South and Southeast geographic regions, low maternal education, and maternal smoking. The low birth weight profile changed, with higher prevalence in more economically developed regions, reflecting the neonatal epidemiological transition determined by changes in patterns of childbirth care and incorporation of perinatal life support technologies, in addition to the previously known biological risks associated with poverty and misinformation.

Abstract
OBJECTIVE To identify non-biological maternal risk factors to low birth weight in Latin America. METHODS Systematic review of literature through meta-analysis. The tool for methodological evaluation was the Strengthening the Reporting of Observational Studies in Epidemiology Statement. Studies in non-pathological maternal risk factors to low-birth weight and those evaluated by a Strengthening the Reporting of Observational Studies in Epidemiology Statement method under C grade were excluded. RESULTS From seven studies, five pointed out the influence of maternal age under 20. In four studies maternal age above 35 years old was relevant to low birth weight. Other factors were present in only one or two studies. CONCLUSION According to this study the maternal age under 20 and above 35 years old is a relevant factor to low birth weight. There are few studies with universal and solid methodology, which difficult a systematic review of literature though meta-analysis.

Abstract
The objective of this study was to identify risk factors for low birth weight in singleton live born infants in Rio Grande do Sul State, Brazil, in 2003, based on data from the Information System on Live Births. The study used both classical multivariate and multilevel logistic regression. Risk factors were evaluated at two levels: individual (live births) and contextual (micro-regions). At the individual level the two models showed a significant association between low birth weight and prematurity, number of prenatal visits, congenital anomalies, place of delivery, parity, sex, maternal age, maternal occupation, marital status, schooling, and type of delivery. In the multilevel models, the greater the urbanization of the micro-region, the higher the risk of low birth weight, while in less urbanized micro-regions, single mothers had an increased risk of low birth considering all live births. Low birth weight varied according to micro-region and was associated with individual and contextual characteristics. Although most of the variation in low birth weight occurred at the individual level, the multilevel model identified an important risk factor in the contextual level.

Abstract
The aim of this study was to perform a systematic review of the use of the Live Birth Information System (Sistema de Informações de Nascidos Vivos--SINASC) in health research. MEDLINE, LILACS and SciELO databases were searched from 1994 to 2005 using the following combination of descriptors: "SINASC", "live birth", "Brazil". We identified 157 abstracts within the reference period, among which 44 were selected and classified according to specific criteria. The number of articles published per year increased during the period studied. The majority of the studies was carried out in the Southeast region and used the municipality as the geographic unity of analysis. A varied range of subjects were assessed including descriptions of live births profiles, health service and programs evaluations and risk factors for infant outcomes. In conclusion, although the SINASC represents an important data source for maternal-infant health research, the system's coverage and the reliability of its data need to be better evaluated.

Abstract
OBJECTIVE To analyze neonatal mortality determinants using multilevel logistic regression and classic hierarchical models. METHODS Cohort study including 138,407 live births with birth certificates and 1,134 neonatal deaths recorded in 2003, in the state of Rio Grande do Sul, Southern Brazil. The Information System on Live Births and mortality records were linked for gathering information on individual-level exposures. Sociodemographic data and information on the pregnancy, childbirth care and characteristics of the children at birth were collected. The associated factors were estimated and compared by traditional and multilevel logistic regression analysis. RESULTS The neonatal mortality rate was 8.19 deaths per 1,000 live births. Low birth weight, 1- and 5-minute Apgar score below eight, congenital malformation, pre-term birth and previous fetal loss were associated with neonatal death in the traditional model. Elective cesarean section had a protective effect. Previous fetal loss did not remain significant in the multilevel model, but the inclusion of a contextual variable (poverty rate) showed that 15% of neonatal mortality variation can be explained by varying poverty rates in the microregions. CONCLUSIONS The use of multilevel models showed a small effect of contextual determinants on the neonatal mortality rate. There was found a positive association with the poverty rate in the general model, and the proportion of households with water supply among preterm newborns.

Abstract
OBJETIVOS: avaliar tendência dos preditores do óbito neonatal entre os nascidos vivos e qualidade do preenchimento do Sistema de Informações para Nascidos Vivos (Sinasc) institucional. MÉTODOS: série histórica do Sinasc do Instituto de Medicina Integral Prof. Fernando Figueira (1995-2006) em Recife, Pernambuco, Brasil. Foram avaliadas: completitude de preenchimento das variáveis e tendência dos indicadores de risco para mortalidade infantil (baixo peso ao nascer; anóxia; prematuridade; cesariana; ausência de pré-natal; mãe adolescente; analfabetismo e nenhum filho nascido vivo e morto). Significância estatística para teste t de Student foi de 5% em um modelo de regressão linear. RESULTADOS: 58.689 nascidos vivos com contínuo incremento a partir de 2002; baixo peso ao nascer, 22,8%; Apgar <7 1º minuto 15,3%; prematuros 22,4%; parto cesáreo 38,2%; mães adolescentes 27,2%; analfabetas 2,7% e 89% sem filho nascido morto. Prevaleceu 1% de variáveis ignoradas. Tendência de aumento (p<0,05): Apgar no 1º minuto, baixo peso ao nascer, prematuridade e parto cesáreo; tendência de declínio(p<0,05): nenhuma consulta de pré-natal, mães adolescentes, analfabetismo e nenhum filho nascido morto. CONCLUSÕES: valores progressivos dos preditores do óbito infantil sugerem problemas na qualidade do pré-natal. Predomínio de 1% de informação ignorada, excelente qualidade de preenchimento do Sinasc institucional. Avaliação rotineira dos nascimentos promove agilidade da informação e intervenções oportunas na prevenção dos óbitos neonatais no nível local.

Abstract
Minerais estão relacionados com todas as etapas de crescimento e diferenciação celular. Quando a gestação coincide com a adolescência a demanda nutricional necessária para ótimo desenvolvimento e crescimento materno e fetal aumenta consideravelmente. Apesar de existirem muitos estudos sobre as funções destes micronutrientes, pouco se sabe sobre suas atuações no resultado da gestação. Este trabalho objetivou revisar na literatura o papel do cobre, ferro, e zinco no resultado da gestação, em especial de gestantes adolescentes, focando intercorrências como baixo peso ao nascer, partos pré-termo, pré-eclampsia, abortos, dentre outras complicações associadas à gestação na adolescência. Os estudos já realizados são limitados, há a necessidade de promovê-los em países em desenvolvimento, onde a deficiência de micronutrientes e intercorrências possuem altos índices. Os benefícios da suplementação de minerais na redução da prevalência de déficits e na melhora dos estoques maternos têm sido demonstrados, mas dados sobre os benefícios potenciais para o feto são pouco conclusivos.

Abstract
A gravidez na adolescência é um problema de saúde pública, podendo trazer consequências negativas para a adolescente, sua família e para o concepto/recém-nascido. Objetivos: Identificar diferenças entre as características sociodemográficas e reprodutivas das mães adolescentes com parto a termo e com parto pré-termo, no Espírito Santo em 2007. Metodologia: Estudo retrospectivo quantitativo. Os dados foram coletados no Sistema de Informação de Nascidos Vivos, sendo realizada análise descritiva de 9.841 Declarações de Nascidos Vivos. A relação entre a variável dependente (termo) e fatores foi testada pelo teste exato de Fisher, com á=0,05. Os resultados evidenciaram que as diferenças nas características das mães adolescentes com parto a termo e pré-termo ocorreram nas seguintes variáveis: idade entre 10 a 14 anos (p=0,016), estado civil casada (p=0,014), número de consultas pré-natais quando insuficientes (p=0,000) e gestação dupla (p=0,000). Houve maior incidência de partos prematuros no Sistema Único de Saúde (p=0,000).

Abstract
OBJECTIVES This study investigated the chronological trend of low-birth weight in full-term babies (TLBW) in Taiwan in the 1980s and 1990s when the nation experienced a rapid economic advancement, and assessed the association between TLBW and parental education and marital status. DESIGN Data from liveborn singletons from Taiwan's birth registry, born between 1978 and 1997, were used to calculate overall and socio-economic factor-specific rates of TLBW for every 2-year interval in this 20-year period. METHODS Logistic regression models were used to assess the trend of TLBW rates, and the interaction between secular time, selected demographic factors and other predictors. RESULTS Among 6,159,070 full-term, liveborn singletons, 208,729 were TLBW. The average annual rate of TLBW was 3.39% in the study period. The period-specific TLBW declined monotonically from 4.41% in 1978-1979 to 2.49% in 1996-1997, representing a 43% deduction. Multiple logistic regression demonstrated persistent declining trends irrespective of the educational level or marital status of the parents. However, the decline was slower for populations of lower socio-economic status, such as less-educated parents and unmarried mothers, which enhanced the inequalities of TLBW risk across populations. The TLBW risk ratios of the least-educated mothers to the most-educated mothers increased from 1.43 in 1978-1979 to 2.05 in 1996-1997. Unmarried status was an independent predictor of elevated risk of TLBW. CONCLUSIONS The association between socio-economic inequality and the risk of TLBW infants was sustained over the 1980s and 1990s in Taiwan. Interventions are necessary to promote antenatal care and educational attainment, particularly for lower socio-economic and socially deprived populations in Taiwan.

Abstract
Este estudo teve como objetivos conhecer a distribuição do peso de nascimento das crianças de Campinas (SP) e indicar fatores de risco para baixo peso. Realizou-se estudo transversal no qual foram utilizados dados das 14.444 Declarações de Nascidos Vivos de 2001. A variável dependente foi o peso de nascimento, e as independentes as características maternas, gestacionais, do parto e do recém-nascido. Na avaliação da associação entre variáveis empregou-se teste de qui-quadrado e calculou-se valores de odds ratio brutos (OR) e ajustados (ORaj). A média do peso de nascimento foi 3.142g, variando de 285 a 5.890g; 65,1% das crianças pesaram 3.000g ou mais, 25,7% entre 2.500 e 2.999g e 9,1% menos de 2.500g. Os determinantes para baixo peso em prematuros foram cesariana, gemelaridade, recém-nascidos femininos e os de mulheres com menos de sete consultas de pré-natal. Para crianças a termo os riscos foram gestação dupla, tripla ou mais, filhos de mulheres com mais de 34 anos, das com até sete anos de estudo, com oito a onze e das com menos de sete consultas de pré-natal. A distribuição de peso de nascimento em Campinas foi inadequada e a proporção de baixo peso foi mais que o dobro dos países desenvolvidos. Os recém-nascidos prematuros que nasceram por cesariana, os prematuros e os a termo de gestação múltipla, os femininos, os de mulheres com pré-natal inadequado e os a termo daquelas com maior idade e baixa escolaridade apresentaram maior chance de nascer com baixo peso.

Abstract
This study was carried in the area covered by the Hospital Universitário of the University of São Paulo in order to verify the relationship between birth weight and maternal work and prenatal, nutritional (height, initial and final weight and weight gain during gestation) and socioeconomic-demographic (age, marital status, level of education, family income) conditions. It was based on a sample of 101 children. The occurrence of low birth weight (LBW) (5.1%) did not show association with maternal work nor with prenatal. On the other hand, LBW showed significant association with the following maternal variables: weight gain during the pregnancy under 7 kilograms, mother's age under 20 years old and marital status (single mothers). Despite the low occurrence of LBW, the results point out to the importance of taking measures to reduce LBW, in particular through the control of prenatal weight gain and prenatal among adolescents. Moreover, a policy of educating women, and in particular single women, about pregnancy, childbirth and nutrition seem an obvious necessity.

Abstract
O objetivo desta revisão é examinar publicações que investigaram o efeito da ansiedade no maior risco de prematuridade e/ou baixo peso ao nascer. Os bancos de dados MEDLINE versão PubMed, BVS, CINAHL e HEALTHSTAR, referentes aos anos de 1966 a 2006, foram rastreados usando-se a combinação dos seguintes descritores: anxiety, pregnancy, low birth weight e prematurity. Foram localizados 13 estudos: 11 coortes, 1 transversal e 1 caso-controle. A maioria (7/13) dos estudos foi realizado nos Estados Unidos. Quatro estudos foram considerados de excelente qualidade, pois excluíram adolescentes e/ou mulheres acima de 34 anos, aferiram a ansiedade a partir do primeiro e/ou segundo trimestre de gestação, utilizaram escalas validadas para medir ansiedade, apresentaram perdas de seguimento inferiores a 30% e controlaram os mais importantes fatores de confusão. A ansiedade na gestação foi associada à prematuridade e/ou ao baixo peso ao nascer em oito estudos. Os valores de razão de chance e risco relativo variaram de 1,08 a 2,31. São necessários estudos cuidadosamente desenhados para esclarecer a relação entre ansiedade na gestação, prematuridade e baixo peso ao nascer, já que as evidências observadas ainda são contraditórias.

Abstract
A análise espacial de indicadores de saúde tem sido um importante instrumento na detecção de diferenciais intra-urbanos. O estudo objetivou traçar um perfil dos nascimentos em Belo Horizonte, Minas Gerais, Brasil, em 2001, analisando a presença de conglomerados espaciais de indicadores de saúde do recém-nascido e suas mães, a partir de dados do Sistema de Informações sobre Nascidos Vivos. Para cada área de abrangência das Unidades Básicas de Saúde, foram calculadas as proporções desses indicadores, utilizando-se o método Bayesiano empírico. Para análise espacial, foram utilizados os índices de Moran global e local (LISA). Áreas com índices de autocorrelação espacial significantes (p < 0,05) foram visualizadas através de mapas. Foram encontrados conglomerados de áreas com índices de autocorrelação espacial significativos para os indicadores adolescentes, menos de oito anos de estudo, filhos mortos em gestações anteriores, cesárea e menos de quatro consultas no pré-natal, guardando relação com as características sócio-demográficas das áreas. A metodologia utilizada configurou-se como um ótimo instrumento de detecção de conglomerados de áreas de risco à saúde materno infantil, podendo facilmente ser incorporada como mecanismo de monitoramento dos eventos relacionados aos nascimentos em Belo Horizonte.

Abstract
OBJETIVOS: caracterizar partos e nascidos vivos de mães residentes no município de Piripiri, Piauí, a partir de dados do Sistema de Informações sobre Nascidos Vivos. MÉTODOS: estudo de corte transversal, de abordagem quantitativa, com dados de 3636 nascimentos ocorridos no triênio 2000-2002. Analisaram-se as variáveis: local de nascimento, sexo e peso do recém-nascido, idade, estado civil e escolaridade da mãe, duração da gestação, tipo de parto e número de consultas de pré-natal. RESULTADOS: quase todos os partos ocorreram no âmbito hospitalar (99,6%). Houve predominância do sexo masculino (51,1%) e freqüência reduzida de baixo peso ao nascer (4,6%). Com relação às mães, observou-se 30% de adolescentes e 74,8% com menos de oito anos de estudo. Verificou-se variação na concentração de nascidos vivos a termo (95,6% em 2000 para 98,3% em 2002), partos vaginais (75,2% em 2000 para 77,5% em 2002) e consultas de pré-natal (78,1% em 2000 para 83,3% em 2002). CONCLUSÕES: o Sistema de Informações sobre Nascidos Vivos apresentou-se como instrumento disponível para o monitoramento da população materno-infantil em nível local. A redução no percentual de preenchimento da categoria "ignorado" no período analisado demonstrou melhoria da qualidade da informação.

Abstract
OBJETIVO: A poluição do ar tem sido investigada como possível determinante do baixo peso ao nascer. O objetivo do estudo foi verificar o efeito da poluição do ar sobre o peso ao nascer. MÉTODOS: Foram analisados todos os partos de mães residentes no Município de São Paulo, nos anos de 1998 a 2000. Estimaram-se as prevalências de baixo peso ao nascer conforme características do recém-nascido, da mãe e do parto. Apenas os distritos mais centrais de São Paulo foram incluídos, totalizando uma amostra de 311.735 nascimentos. Para avaliação do efeito da poluição do ar foram excluídos os prematuros, gemelares e analisados somente os nascimentos das áreas mais centrais da cidade. Os elementos poluentes analisados foram ozônio (O3), dióxido de enxofre (SO2), dióxido de nitrogênio (NO2), partículas em suspensão (PM10) e monóxido de carbono (CO). O efeito da exposição materna à poluição do ar no peso ao nascer foi avaliado por meio de regressão linear e logística. RESULTADOS: Do total analisado, 4,6% dos recém-nascidos apresentaram menos de 2.500 g ao nascer. A exposição materna ao CO, PM10 e NO2 durante o primeiro trimestre de gestação mostrou associação estatisticamente significante com a diminuição no peso do recém-nascido. CONCLUSÕES: Os resultados reforçam que a exposição materna à poluição do ar no primeiro trimestre de gestação pode contribuir para o menor ganho de peso do feto.

Abstract
This study analyzes the spatial distribution of low birth weight (LBW) in the State of Sergipe, Brazil, evaluating the event as a health indicator. The analysis was based on 166,312 live births in the 75 municipalities in the State, using an ecological approach. Four methods were used: cluster analysis, correlation analysis, multiple regression analysis, and multiple comparisons (Tukey). The study shows internal homogeneity in the municipalities' health districts and in the groups resulting from the cluster analysis. Considering a 10% loss of information, seven groups were identified, two of which were residues (Aracaju and Porto da Folha). There is a downward trend in LBW in Sergipe (with a mean of 6.97% during the period), reflecting a slight improvement in quality of life. The causes suggest relations with the environment and are influenced by spatial occupation patterns. The percentage of LBW is a useful indicator of individual risk, but as a collective health indicator it does not appear capable of expressing differences between regions that do not display strong inter-variability.

Abstract
OBJETIVOS: analisar a influência de fatores obstétricos, socioeconômicos e nutricionais sobre o peso do recém-nascido (RN) em uma maternidade de Teresina. MÉTODOS: estudo descritivo realizado com 277 gestantes em trabalho de parto e seus RN, incluindo-se mulheres com idade entre 20 a 34 anos, pré-natal iniciado entre a 10ª e 16ª semana de gestação, idade gestacional >37 semanas, não fumantes, sem doenças, com feto único, vivo e sem má formação congênita e com fichas ou cartão devidamente preenchidos. Para análise estatística, foram utilizados o teste do qui-quadrado, t de Student e análise de variância (p <0,05). RESULTADOS: constatou-se uma população jovem, de baixo poder aquisitivo, escolaridade de oito a mais anos. O incremento semanal médio de peso materno foi 389,3 ± 140,3 g, com ganho total de 12,0 ± 4,6 kg. No tocante aos RN, 73,6% nasceram com peso entre 3000 a 3999 g. Houve associação estatística do peso ao nascer com altura materna (p = 0,001) e total de ganho de peso durante a gestação (p = 0,013). CONCLUSÕES: um adequado ganho de peso durante a gestação e o atendimento pré-natal deve ter um relevante papel em promover essa boa evolução, prevenindo mau prognóstico neonatal.

Abstract
Estudo caso-controle desenvolvido para identificar o efeito dos fatores associados à mortalidade neonatal, analisando variáveis socioeconômicas, de morbidade materna e, em especial, aquelas relacionadas à atenção à saúde. O estudo, realizado em Campinas, SP, incluiu 117 casos e 234 controles. As informações foram obtidas por meio de entrevistas domiciliares. A análise de regressão logística múltipla com modelo hierarquizado identificou como fatores associados ao óbito neonatal as variáveis de nível socioeconômico e de condições da família (renda, naturalidade e número de moradores do domicílio); as variáveis de morbidade materna (sangramento vaginal e parto antecipado por problema de saúde); e as variáveis de atenção à saúde (número de orientações recebidas durante o pré- natal, escolha do hospital do parto e tempo decorrido entre a internação e o parto) e de condições do recém-nascido (idade gestacional, peso ao nascer e Apgar no quinto minuto). O número de consultas de pré-natal não se manteve associado ao óbito neonatal após este ser controlado pela duração da gestação. Conclusão: O estudo aponta a necessidade de melhora da qualidade da atenção pré-natal, especialmente para as gestantes de pior condição socioeconômica e em risco de parto prematuro.

Abstract
OBJETIVOS: estimar alguns fatores de risco para baixo peso ao nascer, em Guaratinguetá, cidade do Sudeste do Brasil, com dados primários obtidos junto a mães que procuraram o setor de vacinação do Sistema Único de Saúde em 1998. MÉTODOS: estudo transversal com amostra de conveniência e correspondente a 598 mães entrevistadas - 28,9% dos partos ocorridos no ano de 1998. As variáveis independentes foram ganho de peso materno, número de consultas realizadas no pré-natal, paridade, infecção no trato gênito-urinário, hipertensão arterial, outros filhos com baixo peso, tabagismo, idade materna e situações conjugal e trabalhista. Utilizou-se regressão logística e foram estimados os riscos relativos e o risco atribuível populacional; o nível de significância foi p < 0,05. RESULTADOS: as variáveis com significância estatística presentes no modelo final foram idade materna inferior a 20 anos (OR = 2,08), outros filhos com baixo peso (OR = 3,94), ganho de peso igual ou menor que 10kg (OR = 1,69), hipertensão arterial (OR = 2,16), e tabagismo (OR = 2,43). CONCLUSÕES: o controle destes três últimos fatores, que pode ocorrer durante o pré-natal ao contrário dos outros dois, pode reduzir em quase 50% a prevalência de baixo peso ao nascer.

Abstract
OBJECTIVE To introduce a fuzzy linguistic model for evaluating the risk of neonatal death. METHODS The study is based on the fuzziness of the variables newborn birth weight and gestational age at delivery. The inference used was Mamdani's method. Neonatologists were interviewed to estimate the risk of neonatal death under certain conditions and to allow comparing their opinions and the model values. RESULTS The results were compared with experts' opinions and the Fuzzy model was able to capture the expert knowledge with a strong correlation (r=0.96). CONCLUSIONS The linguistic model was able to estimate the risk of neonatal death when compared to experts' performance.

Abstract
This study was undertaken using a case-control, prevalence survey design, aimed at verifying the effects of socioeconomic, environmental, and biological/morbidity variables on the growth of schoolchildren from low-income families. The study focused on schoolchildren whose height/age (H/A) ratio was < or = 2SD (NCHS). Control groups were paired according to sex into two groups: C1, whose H/A ratio was between -1SD (NCHS) and the median, and C2, with the H/A ratio > median to +1 SD (NCHS). The Mantel-Haenszel test was used to verify each variable with regard to the H/A ratio, while non-conditional multivariate analysis was used to identify which of the variable blocks had a significant effect and, in the following stage, to identify the variables with a significant effect within each block. In the first stage, the variables with a significant effect for C1 were socioeconomic. For C2, socioeconomic, environmental, and morbidity/biological variables were significant. In the final model, the remaining significant variables for C1 were socioeconomic, while those for C2 were socioeconomic and morbidity/biological. The authors conclude that socioeconomic variables are hierarchically superior to other risk factors.
