Associação entre deficiências físicas e hospitalizações na população da cidade de São Paulo, Brasil

O objetivo foi verificar a associação entre presença de deficiências físicas e hospitalizações na cidade de São Paulo, Brasil. Foi realizado inquérito de saúde na cidade de São Paulo em 2008. Utilizou-se processo de amostragem probabilística, estratificada (sexo/idade) e por conglomerados em dois estágios (setores censitários e domicílios). Os dados foram coletados por entrevistas por meio de um questionário estruturado, com 21 blocos, com a maioria das questões fechadas. A análise inferencial foi realizada com o uso de razões de prevalência (RP) bruta e ajustada e intervalo de 95% de confiança (IC95%) pelo método de regressão de Poisson. O módulo survey do programa Stata 9.2 foi usado para as análises, com significância de 5%. Foram entrevistadas 2.690 pessoas, com idade média de 38,75 anos (IC95%: 37,54-39,96). A hospitalização foi associada à deficiência (auditiva, RP = 1,59; física, RP = 3,77; múltipla, RP = 3,26). As pessoas com deficiência (auditiva, física - paralisia/amputação e múltipla) relataram internações com mais frequência que aquelas sem deficiência.

Exposição ao ruído ocupacional como fator de risco para acidentes do trabalho

OBJETIVO: Verificar se a exposição ocupacional ao ruído é fator de risco relevante para acidentes do trabalho. MÉTODOS: Estudo de caso-controle de base populacional. Os dados foram coletados entre 16/5/2002 e 15/10/2002, na cidade de Botucatu, Estado de São Paulo. Os casos foram definidos como trabalhadores que sofreram acidentes ocupacionais típicos nos últimos 90 dias, identificados por intermédio de amostragem aleatória sistemática de domicílios residenciais. Os controles foram trabalhadores não acidentados, aleatoriamente alocados a partir da mesma população que originou os casos, emparelhados na razão 3:1 segundo sexo, faixa etária e setor censitário de moradia. Ajustou-se um modelo de regressão logística múltipla, tendo como variável independente a exposição ocupacional ao ruído, controlada por covariáveis de interesse. RESULTADOS: Foram analisados 94 casos e 282 controles. Ajustando-se um modelo de regressão logística condicional múltipla observou-se que trabalhar sempre e às vezes exposto a ruído intenso associou-se a um risco relativo de acidentar-se de 5,0 (IC 95%: 2,8-8,7; p<0,001) e 3,7 (IC 95%: 1,8-7,4; p=0,0003), respectivamente, tendo como referência trabalhar não exposto a ruído, controlado para diversas covariáveis. CONCLUSÕES: Com base nos resultados encontrados, justifica-se o investimento em programas de conservação auditiva particularmente voltados para o controle da emissão de ruídos na fonte. Essas medidas objetivam não apenas a manutenção da saúde auditiva, mas também a diminuição da acidentabilidade dos trabalhadores.

Consumo de álcool e risco para doença coronariana na região metropolitana de São Paulo: uma análise do Projeto GENACIS

OBJETIVOS: Examinar a associação entre consumo de álcool e risco para doença coronariana em amostra populacional. MÉTODOS: Estudo transversal, de base populacional, conduzido de janeiro/2006 a junho/2007, na região metropolitana de São Paulo, como parte do estudo internacional (Gender, Alcohol, and Culture: an International Study). Os sujeitos (1.501, sendo 609 homens e 892 mulheres) eram residentes da região metropolitana de São Paulo, tinham 30 anos ou mais de idade e foram selecionados aleatoriamente, a partir de amostragem complexa por conglomerados. Todos os indivíduos consentiram em participar da pesquisa. A variável dependente foi risco cardíaco avaliado através do WHO Rose Angina Questionnaire. A análise multivariada consistiu em regressão logística, tendo sido realizado ajuste para uso de tabaco e índice de massa corpórea. RESULTADOS: A taxa de resposta foi 75%. Ser mulher, ter mais idade, ser negro, fumante e ter um índice de massa corpórea elevado, foram associados a maior risco para doença coronariana. Indivíduos que nunca beberam na vida (OR = 2,22) e ex-bebedores (OR = 2,42) tiveram maior risco de doença cardíaca do que aqueles que informaram beber até 19 g de álcool por dia, sem episódios de beber excessivo. Entre os que tiveram episódios de embriaguês observou-se uma tendência a maior risco (OR = 3,95, p = 0,09). CONCLUSÕES: Nossos achados sugerem um menor risco para doença coronariana entre os bebedores moderados. Destaca-se que os estudos que avaliam o impacto do álcool sobre doença cardíaca precisam identificar o padrão de uso de álcool dos sujeitos, visto que este aspecto pode modificar o risco. Políticas públicas são necessárias para reduzir o uso nocivo de álcool e a morbidade a ele relacionada no país.

Landfills as risk factors for respiratory disease in children

Objective: To investigate the relationship between exposure to a landfill site closed 6 years previously and respiratory symptoms in children aged up to 13 years.Method: This was a cross-sectional study conducted in Varzea Paulista, in the state of São Paulo, Brazil. One adult in every household in a neighborhood close to the landfill and from a randomized sample of households in another neighborhood with similar socioeconomic characteristics but no landfill were interviewed and asked about respiratory symptoms and other variables relating to children aged up to 13. A logistic regression model was used to study this relationship.Results: The likelihood of a child having respiratory symptoms was a function of -2.36 + 0.43 if the child was less than 2 years old; + 0.24 if the child lived in the landfill area; -0.67 if there was a computer at home; + 0.54 if firewood was burnt in the home in the last year; + 0.94 if the child was diagnosed with asthma; + 0.87 if the child visited a health service in the previous 30 days.Conclusion: The authors conclude that living near to a landfill closed 6 years previously may be a risk factor for respiratory disease in children.

An objective reconstruction of the chain of contagion

North's clustering method, which is based on a much used ecological model, the nearest neighbor distance, was applied to the objective reconstruction of the chain of household-to-household transmission of variola minor (the mild form of smallpox). The discrete within-household outbreaks were considered as points which were ordered in a time sequence using a 10-40 day interval between introduction of the disease into a source household and a receptor household. The closer points in the plane were assumed to have a larger probability of being links of a chain of household-to-household spread of the disease. The five defining distances (Manhattan or city-block distance between presumptive source and receptor dwellings) were 100, 200, 300, 400 and 500 m. The subchain sets obtained with the five defining distances were compared with the subchains empirically reconstructed during the field study of the epidemic through direct investigation of personal contacts of the introductory cases with either introductory or subsequent cases from previously affected households. The criteria of fit of theoretical to empirical clusters were: (a) the number of clustered dwellings and subchains, (b) number of dwellings in a subchain and (c) position of dwellings in a subchain. The defining distance closet to the empirical findings was 200 m, which fully agrees with the travelling habits of the study population. Less close but acceptable approximations were obtained with 100, 300, 400 and 500 m. The latter two distances gave identical results, as if a clustering ceiling had been reached. It seems that North's clustering model may be used for an objective reconstruction of the chain of contagious whose links are discrete within-household outbreaks. © 1984.

Avaliação da população canina da zona urbana do Município de Araçatuba, São Paulo, SP, Brasil

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

Care arrangements for people with dementia in developing countries

Background: Rapid demographic ageing will soon lead to large increases in the numbers of persons with dementia in developing countries. This study is the first comprehensive assessment of care arrangements for people with dementia in those regions. Methods: A descriptive and comparative study of dementia care; caregiver characteristics, the nature of care provided, and the practical, psychological (Zarit Burden Interview, General Health Questionnaire) and economic impact upon the caregiver in 24 centres in India, China and South East Asia, Latin America and the Caribbean and Africa. Results: We interviewed 706 persons with dementia, and their caregivers. Most caregivers were women, living with the person with dementia in extended family households. One-quarter to one-half of households included a child. Larger households were associated with lower caregiver strain, where the caregiver was co-resident. However, despite the traditional apparatus of family care, levels of caregiver strain were at least as high as in the developed world. Many had cutback on work to care and faced the additional expense of paid carers and health services. Families from the poorest countries were particularly likely to have used expensive private medical services, and to be spending more than 10% of the per capita GNP on health care. Conclusions: Older people in developing countries are indivisible from their younger family members. The high levels of family strain identified in this study feed into the cycle of disadvantage and should thus be a concern for policymakers in the developing world.

Faecal contamination (viral and bacteria) detection in groundwater used for drinking purposes in São Paulo, Brazil

This project has been developed to evaluate the possible relationship between the cesspit (pit latrine) in as far as it degrades the quality of underground water. Its importance is due to the fact that in the rural communities in the State of São Paulo (Brazil) this type of cesspit is very common as a means of sewage disposal and these communities use underground water for their supply of drinking water. Rural properties distributed over the rural area in the municipality of São José do Rio Preto were selected. A preliminary study was then set up to determine the social situation and health of the households as well as qualitative evaluations on the type of water supply and sewage disposal of these communities. Campaigns of water sampling then followed and laboratory analyses of water taken from wells were carried out. Parameters were set up to evaluate the potability according to Brazilian legislation (2004) paying attention to microbiologic (coliforms, Crytosporidium sp., and adenovirus). The analyses showed evidence of possible interaction between the wells and the sewage effluents and drainage in these communities. A PCR reaction to detect adenovirus showed a presence in 53.3% of the samples. The tests for the detection of Cryotosporidium sp all showed a negative result.

Prevalência de tracoma cicatricial em Botucatu - Estado de São Paulo

Purpose: To evaluate the prevalence of cicatricial trachoma in a population-based sample at Botucatu city-Sao Paulo State, Brazil. Methods: A population-based cross-sectional study with randomized clustered sampling of households was conducted in the urban area of the city of Botucatu, São Paulo State, Brazil. The sample was estimated in 3000 person having been appraised 2554 patient (85,1% of the intended sample) from which 2339 had more than 10 year old at the research time. All the participants were submitted to ophthalmologic examination and the data were statistical analyzed. Results: Three cicatricial trachoma carriers were detected. So, the prevalence of this affection is Botucatu city is 0,13%, affecting mainly over 40'th and having trichiasis. Conclusion: Nevertheless the low prevalence rate of cicatricial trachoma in our region, to prevent trachoma blindness is the cicatrical form of the disease is very important to treat the trichiasis.

Consumption of bottled water by children in the city of Bauru, State of São Paulo, Brazil - A brief communication

Objectives: To determine the consumption of bottled water by children in the city of Bauru, State of São Paulo, Brazil. Methods: A stratified sample of the 17 areas established by the city plan was used to identify a total of 1,000 homes for visitation. Information was collected using a questionnaire concerning the type of water consumed and population demographics. Results: Overall, around 30 percent of all residences used bottled water. Among all households where bottled water was consumed, about 26 percent had children residing. For those with children and bottled water, 81 percent reported to use bottled water for the preparation of the children's foods and beverages. Conclusions: An important percentage of children consume bottled water in the city of Bauru, State of São Paulo, Brazil. Considering previous studies showing that fluoride concentrations vary in bottled water, public health measures should be implemented in order to guarantee adequate levels of fluoride in commercialized water. © 2007, American Association of Public Health Dentistry.

Evaluation of urban ants (hymenoptera: formicidae) as vectors of microorganisms in residential and industrial environments: II. Fungi

Collections in households and industrial kitchens were done aiming at evaluating the potential of urban ants in spreading fungi. The most abundant ant species in households were Tapinoma melanocephalum and Paratrechina longicornis. In industrial kitchens Paratrechina longicornis and Monomorium floricola were the most common. Tapinoma melanocephalum was the species that most carried fungi, followed by Paratrechina longicornis, Tetramorium sp., Monomorium pharaonis and Monomorium floricola. An aflatoxigenic strain of Aspergillus flavus was isolated.
