Análise espacial da incidência de câncer de próstata no estado da Bahia

Abstract

This work aims to carry out a spatial analysis of the incidence of prostate cancer in the state of Bahia. Understanding the spatial pattern of patients with prostate cancer is of great importance, as it allows directing the basic care of these people and provides a solid basis for planning public health policies. First, an analysis of the raw data incidence rates was performed to discover possible trends and patterns related to the studied variables. Adjustments were made by the Moran Local Index to control the volatility of rates caused by the low number of cases related to the population of the municipalities. When comparing the crude incidence rates and the leveled incidence rates using the Bayesian method, differences were found in the spatial distribution and risk areas were determined, with the coastal strip that contains the metropolitan region of Salvador considered a high risk area in the state and parts of the western region of Bahia, being considered a low-risk cancer incidence area. The results showed that the local Moran index proved to be effective in detecting spatial patterns, as it applies neighborhood information in its calculations, in addition to providing greater inspection of the incidence rates under study.
