Objective: To analyze the correlation between colorectal cancer (CRC) mortality rates and socioeconomic factors in the five mesoregions (North, Northeast, Southeast, Southwest and Center-South) of the state of Mato Grosso, from 2005 to 2016.
Methods: Ecological study that considered deaths from CRC (C18 to C21) of residents of the state. Mortality rates were standardized by the direct method, using the world standard population. For the analysis of socioeconomic factors, the Firjan Municipal Development Index (IFDM) and its components (education, income and employment and health) were used. Means of mortality rates and socioeconomic factors between the mesoregions were tested using ANOVA, and Pearson's correlation coefficient was used to analyze the correlation between mortality rates due to CRC and these factors.
Results: In the period from 2005 to 2016, 1,492 deaths from CRC were registered in the state of Mato Grosso. The Southwest mesoregion had the highest average for both the crude rate and standardized CRC mortality rates (3.47 and 3.86 deaths/100,000 inhabitants, respectively). There was a significant correlation between mortality rates from the disease with the following indicators: Overall IFDM for the North, Southeast and Center-South mesoregions; education for the North and Southeast mesoregions; income and employment for the North and Center-South mesoregions; and health for the North, Southeast and Center-South mesoregions.
Conclusion: There was a correlation between CRC mortality rates and better socioeconomic development in the state.
