Resumo: OBJECTIVE: To analyze the dengue epidemic in relation to the socioeconomic context according to geographical areas. METHODS: An ecological study was conducted in the municipality of Rio de Janeiro (Southeastern Brazil), in areas delimited as neighborhoods, based on information about notified dengue cases concerning residents in the municipality. The average incidence rate of dengue was calculated between the epidemiological weeks: 48th of 2001 and 20th of 2002. The occurrence of dengue was correlated with socioeconomic variables through Pearsons' correlation coefficient. Moran's global and local indexes were used to assess the spatial auto-correlation between dengue and the variables that significantly correlated with the disease. The multiple linear regression model and the conditional auto-regression spatial model were used to analyze the relationship between dengue and socioeconomic context. RESULTS: The neighborhoods located in the west zone of the municipality presented high rates of average dengue incidence. The variables presenting significant correlation were: percentage of households connected with the general sanitary network, households with washing machines, and population density per urban area. Moran's spatial auto-correlation index revealed spatial dependence between dengue and the selected variables. The utilized models indicated percentage of households connected with the general sanitary network as the sole variable significantly associated with the disease. The residual figures in both models revealed significant spatial auto-correlation, with a positive Moran Index (p

MÉTODOS: Fue realizado estudio ecológico en el municipio de Río de Janeiro (Sureste de Brasil), en áreas delimitadas como urbanizaciones, a partir de informaciones de casos de dengue notificados y residentes en el municipio. Fue calculada la tasa de incidencia promedio de dengue entre las semanas epidemiológicas: 48ª de 2001 a 20ª de 2002. La ocurrencia de dengue fue correlacionada con variables socioeconómicas utilizándose el coeficiente de correlación de Pearson. Se utilizó el Índice de Moran global y local para evaluar la autocorrelación espacial del dengue y de las variables correlacionadas significativamente con la enfermedad. Fueron usados el modelo de regresión lineal múltiple y el modelo espacial condicional auto-regresivo para analizar la relación entre dengue y contexto socioeconómico. RESULTADOS: Las urbanizaciones de la zona oeste del municipio presentaron elevadas tasas de incidencia promedio de dengue. Presentaron correlación significativa las variables: porcentaje de domicilios ligados a la red sanitaria general, domicilios con lavadora de ropas y densidad poblacional por área urbana. El índice de autocorrelación espacial Moran reveló dependencia espacial entre el dengue y variables seleccionadas. Los modelos utilizados apuntaron el porcentaje de domicilios ligados a la red sanitaria general como única variable asociada significativamente a la enfermedad. Los residuos de ambos modelos revelaron autocorrelación espacial significativa, con índice de Moran positivo (p OBJETIVO: Analisar a epidemia de dengue em relação ao contexto socioeconômico segundo áreas geográficas.
