“…9,14 Given the need to increase the understanding of the dynamics of production and transmission of HIV/AIDS infection, instruments traditionally used in GIS can be useful to identify areas with a greater concentration of cases, in addition to enabling the identifi cation of places with higher risk of infection, using statistical models with greater explanatory potential. 1,2,3 The use of georeferenced points in maps allows greater accuracy of analysis, because it is assumed that possible inner differences and inequalities in an area, divided into polygons, will not disappear. Thus, the onset of a disease is the focus, as a result of the demographic and social structure of the city and its differentiation in the country.…”

“…4,11 The spatial dissemination of AIDS has been investigated, using geoprocessing and spatial data analysis, increasing the understanding of the dynamics of this epidemic in Brazil and enabling public health to have tools traditionally used in geography and cartography. 2,5,14 Health services have also incorporated statistical analyses, computer programs and geographic information systems (GIS), particularly in programs of epidemiological surveillance of diseases. In this way, space began to be thoroughly analyzed, bringing important contribution to epidemiological studies and the performance of health services.…”

OBJECTIVE:To analyze the spatial distribution of reported AIDS cases in adults and its association with living conditions in the city of Campinas, Southeastern Brazil. METHODS:Data on AIDS cases in men (n=2,945) and women (n=1,230) aged more than 13 years and living in Campinas, recorded in the SINAN (Brazilian Information System for Notifi able Diseases), were used to map the spatial distribution of this disease and the male:female ratio. Maps were constructed for the following periods: from 1980 to 1995, from 1996 to 2000, and from 2001 to 2005. The variables included in the analysis were address, sex and age. A weighted composite index was used to study living and health conditions in the area. Patients' home addresses were geocoded on a cartographic base, after correction and standardization according to a reference database of streets. A generalized additive model was adjusted to analyze the spatial distribution of the ratio of male:female cases in space, in the three study periods. RESULTS:The ratio of male:female cases was higher in areas with better living conditions (central) and around the prison (northwestern), where families of prisoners and former prisoners live temporarily, while this ratio was lower in the city suburbs (southwestern). CONCLUSIONS:The trends towards the AIDS epidemic affecting more women and poorer individuals were confi rmed by the decrease in the ratio of male:female cases in the period, particularly in vulnerable and impoverished populations. Geographic information systems and spatial data analysis can be useful for AIDS control and surveillance actions.

“…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.

“…9 Previous studies of HIV-positive pregnant women in Porto Alegre documented clustering of areas with high prevalence rates and a substantial proportion of people living in shantytowns (favelas) along the city fringes. 2 Social inequalities in poor areas often comprise different components such as barriers to health service access 5 and high rates of pregnancy among adolescents. 4 Initiatives aiming to curb mother-to-child HIV transmission have to be comprehensive integrating health surveillance and care.…”

OBJECTIVE:To identify clustering areas of infants exposed to HIV during pregnancy and their association with indicators of primary care coverage and socioeconomic condition. METHODS:Ecological study where the unit of analysis was primary care coverage areas in the city of Porto Alegre, Southern Brazil, in 2003. Geographical Information System and spatial analysis tools were used to describe indicators of primary care coverage areas and socioeconomic condition, and estimate the prevalence of liveborn infants exposed to HIV during pregnancy and delivery. Data was obtained from Brazilian national databases. The association between different indicators was assessed using Spearman's nonparametric test. RESULTS:There was found an association between HIV infection and high birth rates (r=0.22, p<0.01) and lack of prenatal care (r=0.15, p<0.05). The highest HIV infection rates were seen in areas with poor socioeconomic conditions and diffi cult access to health services (r=0.28, p<0.01). The association found between higher rate of prenatal care among HIV-infected women and adequate immunization coverage (r=0.35, p<0.01) indicates that early detection of HIV infection is effective in those areas with better primary care services. CONCLUSIONS:Urban poverty is a strong determinant of mother-to-child HIV transmission but this trend can be fought with health surveillance at the primary care level.
