Mortalidade infantil e condições socioeconômicas nas microrregiões do Nordeste Brasileiro

The study aims to answer the following question: what are the different profiles of infant mortality, according to demographic, socioeconomic, infrastructure and health care, for the micro-regions at the Northeast of Brazil? Thus, the main objective is to analyze the profiles or typologies associated mortality levels sociodemographic conditions of the micro-regions, in the year 2010. To this end, the databases of birth and death certificates of SIM and SINASC (DATASUS/MS), were taken from the 2010 population Census microdata and from SIDRA/IBGE. As a methodology, a weighted multiple linear regression model was used in the analysis in order to find the most significant variables in the explanation child mortality for the year 2010. Also a cluster analysis was performed, seeking evidence, initially, of homogeneous groups of micro-regions, from of the significant variables. The logit of the infant mortality rate was used as dependent variable, while variables such as demographic, socioeconomic, infrastructure and health care in the micro-regions were taken as the independent variables of the model. The Bayesian estimation technique was applied to the database of births and deaths, due to the inconvenient fact of underreporting and random fluctuations of small quantities in small areas. The techniques of Spatial Statistics were used to determine the spatial behavior of the distribution of rates from thematic maps. In conclusion, we used the method GoM (Grade of Membership), to find typologies of mortality, associated with the selected variables by micro-regions, in order to respond the main question of the study. The results points out to the formation of three profiles: Profile 1, high infant mortality and unfavorable social conditions; Profile 2, low infant mortality, with a median social conditions of life; and Profile 3, median and high infant mortality social conditions. With this classification, it was found that, out of 188 micro-regions, 20 (10%) fits the extreme profile 1, 59 (31.4%) was characterized in the extreme profile 2, 34 (18.1%) was characterized in the extreme profile 3 and only 9 (4.8%) was classified as amorphous profile. The other micro-regions framed up in the profiles mixed. Such profiles suggest the need for different interventions in terms of public policies aimed to reducing child mortality in the region

Mortalidade infantil em município da região Centro-Oeste Paulista, Brasil, 1990 a 1992

INTRODUÇÃO: A mortalidade infantil em Presidente Prudente, SP (Brasil), foi estudada no período de 1990 a 1992, a partir de aplicação de métodos para obtenção de diagnóstico coletivo que orientassem a identificação e escolha de estratégias de controle de problemas locais. MATERIAL E MÉTODO: Foram utilizadas declarações de óbito colhidas no cartório, cujos dados originais foram corrigidos por meio de pesquisa documental nos serviços de saúde e entrevistas domiciliares. Para estudar variáveis como idade materna e peso ao nascer foram utilizados os dados do Sistema de Informações sobre Nascidos Vivos (SINASC). A qualidade dos dados originais das declarações de óbitos foi inicialmente analisada pela quantidade de informações, sensibilidade, especificidade e valor de Kappa. RESULTADO: A sensibilidade global para a causa básica de óbito foi 78,84% e Kappa igual a 71,32 para o total de causas. Ocorreram 189 óbitos, sendo 66,15% no período neonatal (41,28% durante o primeiro dia de vida) e 33,85% no infantil tardio. O peso ao nascer de 58,28% dos óbitos foi menor que 2.500g. As causas básicas de óbito foram estudadas segundo a possibilidade de serem prevenidas (método desenvolvido por Erica Taucher) por grupos de causas reduzidas utilizadas no International Collaborative Effort (ICE), causas múltiplas e distribuição geográfica. Observou-se que nos óbitos ocorridos até 27 dias, 22,23% poderiam ser evitados por adequada atenção ao parto, 20,64% seriam redutíveis por diagnóstico e tratamento precoce, 13,75% por bom controle da gravidez e apenas 7,94% não evitáveis. Das mortes ocorridas no período infantil tardio, 12,17% foram classificadas como outras preveníveis e 4,23% foram consideradas não evitáveis. Segundo os grupos do ICE, 58,74% faleceram por imaturidade ou asfixias; 19,58% por infecções e, 12,17%, por anomalias congênitas. CONCLUSÃO: Os resultados sugerem prioridade para assistência obstétrica no trabalho de parto e atenção pediátrica por baixo peso ao nascer, entre outras. A análise por causas múltiplas mostra que 76,05% dos óbitos têm as causas básicas relacionadas a causas perinatais e confirma a relação entre as deficiências de peso e as complicações respiratórias do recém-nascido. As complicações maternas também relacionaram-se com o baixo peso. Identificaram-se grandes diferenças no coeficiente de mortalidade infantil entre as áreas da zona urbana não somente restritas aos valores, como também ao tipo de doenças responsáveis pela ocorrência do óbito. Conclui-se haver vantagem no uso associado das quatro técnicas que são complementares, tanto para estudo, como para planejamento de ações dirigidas à prevenção da mortalidade infantil.

Desigualdade regional da mortalidade neonatal no Brasil

In Brazil, despite the decline in infant mortality in recent decades it still has high rates going against recommended by WHO. Being the largest percentage of infant mortality rate composed of neonatal deaths. Objective: A study was conducted to analyze the spatial distribution of neonatal mortality and its correlation with the biological, socioeconomic and maternal and child health care in the Brazilian states in the period from 2006 to 2010. Method: The study made thematic maps and correlation (LISA) for verification of spatial dependence and multiple linear regression models. Results: Was found that there is no spatial autocorrelation for neonatal mortality in the Brazilian states (R = 0.002, p = 0.48). Most of variables were correlated (r> 0.3, p <0.05) with neonatal mortality, forming clusters in the North and Northeast, with the highest rates of teenage mothers, low household income per capita, lower prenatal appointments and beds of Neonatal Intensive Care Unit. The number of Neonatal UCI beds remained independent effect after regression analysis. Conclusion: The study concludes that regional inequalities in living conditions and especially the access to maternal and child health services contribute to the unequal distribution of neonatal mortality in Brazil

Acquired immunodeficiency syndrome in Brazil

Aim. To describe the acquired immunodeficiency syndrome (AIDS) epidemic in Brazil and analyze the impact of federal government measures addressing the problem since its onset.Method. Retrospective review of AIDS epidemic data from its onset in 1980 up to the last published data in June 2001.Results. AIDS was first reported in Brazil in 1980. By 1988, all 27 Brazilian states had diagnosed cases, and until June 2000 more than half of Brazilian municipalities had recorded at least one case of the disease. The AIDS incidence reached its peak between 1996 and 1997 (14.7 per 100,000 population), and then declined between 1998 and 2000 to 9 per 100,000 population. In the last two decades, the proportion of deaths has been also significantly reduced. These were not random events, but reflected the efficiency of the program implemented by the Brazilian Health Ministry's Coordination on Sexually Transmitted Diseases and AIDS. The program includes an epidemiological surveillance modeling system, which records cases from several regular epidemiological bulletins; national network of diagnosis and monitoring of HIV-infected individuals (ill or not); highly active antiretroviral therapy available free to all patients; mother-infant protection program; educational programs on condom use; the introduction of the female condom; development of AIDS studies in different areas to provide practical solutions; constant preoccupation about drug costs accounting for the patent breaking; and national production of many drugs currently in use.Conclusion. Well-planned and implemented national program against AIDS can significantly reduce the burden of this disease to the population.

Social support and infant malnutrition: a case-control study in an urban area of Southeastern Brazil

The relationship between malnutrition and social support was first suggested in the mid-1990s. Despite its plausibility, no empirical studies aimed at obtaining evidence of this association could be located. The goal of the present study was to investigate such evidence. A case-control study was carried out including 101 malnourished children (weight-for-age National Center for Health Statistics/WHO 5th percentile) aged 12-23 months, who were compared with 200 well-nourished children with regard to exposure to a series of factors related to their social support system. Univariate and multiple logistic regressions were carried out, odds ratios being adjusted for per capita family income, mother's schooling, and number of children. The presence of an interaction between income and social support variables was also tested. Absence of a partner living with the mother increased risk of malnutrition (odds ratio 2.4 (95 % CI 1.19, 4.89)), even after adjustment for per capita family income, mother's schooling, and number of children. The lack of economic support during adverse situations accounted for a very high risk of malnutrition (odds ratio 10.1 (95 % CI 3.48, 29.13)) among low-income children, but had no effect on children of higher-income families. Results indicate that receiving economic support is an efficient risk modulator for malnutrition among low-income children. In addition, it was shown that the absence of a partner living with the mother is an important risk factor for malnutrition, with an effect independent from per capita family income, mother's schooling, and number of children.

Mortalidade infantil em município do interior do estado de São Paulo

Considerando que a mortalidade infantil é indicador dos níveis de saúde da população, realizamos este trabalho, cujo objetivo foi identificar as causas de mortalidade infantil no ano de 1998 em Botucatu. O coeficiente de mortalidade infantil obtido foi 12/1000 NV, com maior participação dos óbitos neonatais - 8,3/1000 NV A maior parte dos óbitos foi classificada como reduzível ou parcialmente reduzível, mas a atenção necessária para viabilizar tal redução foi variada. Dos óbitos ocorridos, 21,7% eram inevitáveis, evidenciando que para redução dos índices de mortalidade infantil deveremos continuar investindo na qualidade da assistência à saúde e melhoria das condições de vida da população.

Caries and its association with infant feeding and oral health-related behaviours in 3-4-year-old Brazilian children

Objectives: To investigate the relationships between socio-demographic factors, infant feeding habits, oral hygiene and the prevalence and patterns of caries in Brazilian 3-4-year-olds. Methods: Systematic random sampling was used to select children enrolled in municipal nurseries in Araraquara, Brazil, in 1998. Clinical examinations were carried out by one examiner using dmft and dmfs indices and WHO criteria. Questionnaires for information related to the socio-demographic background, oral hygiene and dietary history of the children were completed by their mothers. Results: Caries was seen in 46% of the children; 17% of them had the more extensive pattern involving molars and incisors. Social class, mother's education, and age at which breast-feeding terminated showed statistically significant associations with caries. Feeding bottles with added sugars were still being given to 80% of the children. When the significant variables were taken into account only age at which breast-feeding terminated showed a significant relationship to the pattern of disease. Children who were never breast-fed or were breast-fed beyond the age of 24 months had a higher prevalence of the more extensive pattern of caries. Conclusions: The association between the length of time a mother breast-feeds and extensive caries should be a consideration in any local infant feeding policies or health promotion strategies. The duration for appropriate breast- or bottle-feeding should be emphasised.

Mortalidade por causas externas no Município de São José do Rio Preto, no período de 1996-1998

Introduction: An epidemiological study of the mortality rates by injuries in São José do Rio Preto, State of São Paulo, Brazil, has been carried out. The period considered is 1996-1998. Objectives: To show injuries mortality rates in São José do Rio Preto-SP in 1996-98. Methods: The study was based on official data from the Mortality Information Service of the Brazilian Ministry of Health, and in a survey based on data from medical forensic examiners (IML). Software Epinfo6.0 and Tabwin was utilized for data analises. Results: The results were compared to values obtained in the literature for the other cities of São Paulo and Brazil. In the case of São José do Rio Preto, was observed a decrease in the number of deaths associated with external causes in the period, but particularly in deaths due to traffic accidents with motor vehicles an increase in cases of pedestrians killed by hit-and-run drivers, that is much larger than the corresponding values for Brazil and for the State of São Paulo. The study showed increase in rates of homicides, mainly in the 15 to 39 years age group. Conclusion: This result suggests that is important to start programs to reduce the number of deaths by injuries, as well as the necessity of monitoring locally all these data.

Growth and developmental outcomes of the extremely preterm infant

Objetive: To provide information for pediatricians and neonatologists to create realistic outcome expectations and thus help plan their actions. Sources of data: Searches were made of the Cochrane Library, MEDLINE, and Lilacs databases. Summary of the findings: The assessment of growth and development over the first 2-3 years must adjust chronological age with respect of the degree of prematurity. There is special concern regarding the prognoses of small for gestational age preterm infants, and for those with bronchopulmonary dysplasia. Attention must be directed towards improving the nutrition of extremely low birth weight infants during their first years of life; these infants have high prevalence levels of failure to catch-up on growth, diseases and rehospitalizations during their first 2 years. They are frequently underweight and shorter than expected during early childhood, but delayed catch-up growth may occur between 8 and 14 years. Extremely low birth weight infants are at increased risk of neurological abnormalities and developmental delays during their first years of life. Educational, psychological, and behavioral problems are frequent during school years. Teenage and adult outcomes show that although some performance differences persist, social integration is not impaired. Conclusions: The growth and neurodevelopment of all ELBW infants must be carefully monitored after discharge, to ensure that children and their families receive adequate support and intervention to optimize prognoses.

Oral cancer mortality trends in Brazilian geographical regions from 1996-2001

The purpose of this study was to analyse the oral cancer mortality trends in Brazil by geographic region, age and sex, from 1996 to 2001. The Brazilian Ministry of Health database DATASUS and the Brazilian Institute of Geography and Statistics were used as the source of data. Oral cancer mortality rates per 100,000 population were estimated. Statistical analyses comprised estimates of oral cancer mortality rates, grouped according to the study variables, in 1996, 1997, 1998, 1999, 2000 and 2001; also, the three-year periods 1996-1998 and 1999-2001 were analysed, allowing the oral cancer mortality trends between these two periods to be calculated. For comparison, in each geographical region, the ratio between two death rates (related to period or sex) was calculated. In the period 1996-2001, a total of 25,972 deaths due to oral cancer were reported, giving a mortality rate of 2.67. The rates for the periods 1996-1998 and 1999-2001 were 2.53 and 2.73, respectively, showing a slight increase in the rate. There was a predominance of oral cancer in males with a male/female ratio of approximately 4. All regions exhibited an increase in mortality rates, with the exception of the Southeast region. From 1996 to 2001, the average mortality rates were 3.55 and 3.58 for the Southeast and South regions, and 1.94, 1.41, and 0.86 for the Mid-West, Northeast, and North regions, respectively. Over the age of 40, oral cancer mortality rates were seen to increase rapidly with age. Oral cancer mortality increased in all regions, except in the Southeast, and was considerably higher among males and older individuals.

Ocorrência de infecção urinária em pacientes de um hospital universitário

Infection in hospitals is a serious problem for the Public Health System. It is responsible for the increasing number of hospital deaths, as well as the longer time patients may have to stay in hospital, raising the costs of confinement more and more. The most common hospital infection is urinary tract infections (UTI), the use of the urinary catheter being the main risk factor. The aim of this study was to evaluate the profile of UTI among hospitalized patients in a University Hospital in Brazil, from October to December 2003. Out of 271 samples of urine checked, 51 were positive, 27 of these from patients having community-acquired UTI and 24 whose infection originated in the hospital. The community-acquired UTIs were more frequent in female patients (63%). The highest incidence of infection was caused by Escherichia coli (74%), especially in patients aged from 0 to 15 (37%). The episodes of hospital-acquired infection happened, in the main, in male patients aged above 50 (68%) who were using a lasting vesical catheter; in this group of patients the infection was frequently caused by E. coli (29.1%) and Klebsiella spp. (29.1%). E. coli and Klebsiella pneumoniae exhibited strong resistance (62.5%) to trimethoprim-sulfamethoxazole, as well as to ampicillin, showing that these drugs should not be used to cure UTIs in this institution.
