“…Inclusion of geographic information in the study allows for visualization of the spatial distribution of cases and improves analysis of relationships between environment and development of infections. [1][2][3] The study objective was to describe the relationship between HIV infection in pregnant women and VT, according to socioeconomic profi le of the mother's residential neighborhood. The prevalence of infected pregnant women was calculated.…”

OBJECTIVE:To describe HIV prevalence in pregnant women and the rate of vertical transmission according to socioeconomic status of residential neighborhoods. METHODS:Ecological exploratory study, which used the Information System of Notifi able Diseases database on HIV-positive pregnant women and AIDS in children, reported from 2000 to 2006, in Vitória, Southeastern Brazil. For analysis of socioeconomic data the Urban Quality Index was utilized The HIV prevalence rate in pregnant women and vertical transmission rate were calculated. Spatial distribution was carried out by Terraview 3.2.0. To verify the association between urban quality and HIV prevalence in pregnant women, Poisson regression was used. RESULTS:A total of 137 HIV-positive women and 14 children infected by vertical transmission was reported. Seven children matched to HIV-positive mothers without notifi cation in the period analyzed. HIV prevalence among pregnant women in the period was 0.44%, and the vertical transmission rate was 9.7%. CONCLUSIONS:The prevalence of HIV infection among pregnant women and vertical transmission were associated with the urban quality of residential neighborhood. Neighborhoods with lower urban quality should be prioritized in actions to reduce vertical transmission.

Análise espacial da ocorrência de dengue e condições de vida na cidade de Nova Iguaçu, Estado do Rio de Janeiro, Brasil

A reemergência da dengue, sua disseminação e manutenção vêm desafiando o sistema de saúde brasileiro. Fatores relacionados às condições de vida da população têm sido abordados na compreensão de diferentes desfechos em saúde. Este trabalho analisa a ocorrência da dengue e sua relação com as condições de vida no Município de Nova Iguaçu, Rio de Janeiro, Brasil, de 1996 a 2004. Os dados sobre ocorrência de dengue foram obtidos no Sistema de Informação de Agravos de Notificação (SINAN). Para caracterização das condições de vida, foi construído um indicador composto com variáveis sócio-econômicas e de infra-estrutura urbana coletadas no Censo Demográfico de 2000. Operações entre camadas foram utilizadas para identificar associações espaciais entre o indicador composto e a incidência de dengue por bairros. Apesar de não se evidenciar uma relação linear entre condições de vida ruins e ocorrência da doença, os padrões espaciais observados indicaram maior suscetibilidade de áreas com desigualdades nas condições de vida e localizadas próximas às vias de acesso. Os achados sugerem ainda que, além de outros fatores relacionados à ocorrência da doença, as desigualdades observadas podem interferir na tendência temporal da dengue. Assim, modelos que considerem a interação entre variáveis sócio-econômicas e não apenas a quantificação de indicadores sociais isolados podem ser úteis para a vigilância da dengue.

The relationships between environmental exposure to risk agents and health conditions have been studied with the aid of remote sensing imagery, a tool particularly useful in the study of vegetation cover. This study aims to evaluate the influence of environmental variables on the spatial distribution of the abundance of Lutzomyia longipalpis and the reported canine and human visceral leishmaniasis (VL) cases at an urban area of Campo Grande, state of Mato Grosso do Sul. The sandfly captures were performed in 13 residences that were selected by raffle considering four residences or collection station for buffer. These buffers were generated from the central house with about 50, 100 and 200 m from it in an endemic area of VL. The abundance of sandflies and human and canine cases were georreferenced using the GIS software PCI Geomatica. The normalized difference vegetation index (NDVI) and percentage of land covered by vegetation were the environmental variables extracted from a remote sensing IKONOS-2 image. The average NDVI was considered as the complexity of habitat and the standard deviation as the heterogeneity of habitat. One thousand three hundred sixty-seven specimens were collected during the catch. We found a significant positive linear correlation between the abundance of sandflies and the percentage of vegetation cover and average NDVI. However, there was no significant association between habitat heterogeneity and the abundance of these flies
