Resumo Objetivo analisar a distribuição espacial da mortalidade fetal por sífilis congênita entre os bairros do Município do Recife-PE. Método estudo ecológico, realizado a partir do indicador epidemiológico taxa de mortalidade fetal por sífilis congênita, agregado ao nível dos bairros, em dois quinquênios: 2007 a 2011 e 2012 a 2016. O padrão de autocorrelação espacial foi determinado pelos Índices de Moran Global e Local, com significância estatística inferior a 5% e representado em mapas BoxMap e MoranMap que apontaram as áreas com taxas altas, baixas e em transição epidemiológica e os clusters de maior interesse epidemiológico. Resultados foram notificados 208 óbitos fetais. O Índice Global de Moran evidenciou autocorrelação espacial positiva em grau razoável, no primeiro quinquênio (I = 0,351 e p-valor = 0,01) e, em grau fraco, no segundo quinquênio (I = 0,189 e p-valor = 0,02). Os Distritos Sanitários I e VII obtiveram os maiores percentuais de bairros que formaram o cluster de altas taxas do indicador com 63,3% e 38,4% no primeiro e segundo quinquênios, respectivamente. Conclusões e implicações para a Prática a análise espacial apontou as áreas críticas para ocorrência do indicador, podendo contribuir para o investimento nas áreas prioritárias de prevenção da transmissão vertical da sífilis.
Objectives: to analyze the variation in the incidence rates of congenital syphilis according to the spatial distribution of Life Condition Index (LCI) among neighborhoods in the city of Recife-PE. Methods: an ecological study, developed from 3,234 cases of congenital syphilis notified in the Sistema de Informação de Agravos de Notificação (Severe Disease Notification Information System), between 2007 and 2016. LCI was built from seven variables related to the dimensions of the environment, education and income, aggregated at the neighborhood levels and spatially distributed in four strata: very high, high, low and very low. The correlation between the rates of congenital syphilis in the strata and LCI was investigated by applying the Spearman correlation coefficient and demonstrated by means of scatter graphics. Results: the mean rate on disease incidence was 6.8 cases per thousand live births. There was a higher incidence in the strata of very low and low living conditions, as well as in Districts that presented poor sanitary conditions and low schooling for the head of the family (District VII), higher proportion of illiteracy among 10 and 14 year olds (District II) and low income of the head of the household (Districts I, II and VII). Conclusions: this study showed the persistence of health inequalities in areas with worse living conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
