Resumo: | OBJECTIVE: To assess the association between Aedes aegypti larvae infestation rates and socioeconomic factors. METHODS: Infestation rates in the urban area of the city of São José do Rio Preto, Southeastern Brazil, were calculated in January of 2005 and subsequently geocoded by address. The urban census tracts were grouped by means of main component analysis, thus producing four socioeconomic clusters (1-4, in a decreasing order of socioeconomic level) and a fifth cluster (5) with a level below the others and not belonging to the urban census tracts (new districts and irregular residential development projects). The Breteau index (BI), the house index (HI), and the container index (CI), as well as the averages of existing containers surveyed per home, were calculated for each cluster. RESULTS: The values of infestation indices did not show significant differences among socioeconomic clusters 1 to 4, even though they were lower than the indices obtained for cluster 5. The averages of existing containers surveyed were higher for cluster 1 in relation to clusters 2 to 4, but did not show significant differences when compared to cluster 5. CONCLUSIONS: Larval indices did not show association with the different socioeconomic levels of the cluster that corresponds to the urban census tracts. Nonetheless, new districts, irregular residential development projects and locations adjacent to those with the worst basic sanitary conditions showed the highest values for these indicators. |

OBJETIVO: Analisar a associação entre índices de infestação larvária por Aedes aegypti e fatores socioeconômicos. MÉTODOS: Foram calculados os índices de infestação na área urbana de São José do Rio Preto, São Paulo, em janeiro de 2005 e em seguida geocodificados por endereço. Os setores censitários urbanos foram agrupados por meio de análise de componentes principais, produzindo quatro áreas socioeconômicas (1-4, ordem decrescente de nível socioeconômico) e um quinto agrupamento (5) com nível inferior aos demais e não pertencente aos setores censitários urbanos (bairros novos e loteamentos irregulares). Calcularam-se, para cada área, os índices de Breteau (IB), predial (IP) e de recipientes (IR), e as médias de recipientes existentes e pesquisados por casa. RESULTADOS: Os valores dos índices de infestação não apresentaram diferenças significativas entre as áreas socioeconômicas 1 a 4, mas foram menores que os índices obtidos para a área 5. As médias de recipientes existentes e pesquisados foram maiores para a área 1 em relação às áreas 2 a 4, mas não apresentaram diferenças significativas em relação à 5. CONCLUSÕES: Os índices larvários não mostraram associação com os diferentes níveis socioeconômicos da área correspondente aos setores censitários urbanos. Entretanto, os bairros novos, loteamentos irregulares e locais contíguos com as piores condições de saneamento básico apresentaram os maiores valores desses indicadores. Universidade de São Paulo.
