Increase Income and Mortality of Colorrectal Cancer in Brazil, 2001-2009

Abstract

ContextSeveral international studies have observed a correlation between the improvement of socio-demographic indicators and rates of incidence and mortality from cancer of the colon and rectum.ObjectiveThe objective of this study is to estimate the correlation between average per capita income and the rate of colorectal cancer mortality in Brazil between 2001 and 2009.MethodsWe obtained data on income inequality (Gini index), population with low incomes (½ infer the minimum wage/month), average family income, per capita ICP and mortality from colon cancer and straight between 2001-2009 by DATASUS. A trend analysis was performed using linear regression, and correlation between variables by Pearson's correlation coefficient.ResultsThere was a declining trend in poverty and income inequality, and growth in ICP per capita and median family income and standardized mortality rate for colorectal cancer in Brazil. There was also strong positive correlation between mortality from this site of cancer and inequality (men r = -0.30, P = 0.06, women r = -0.33, P = 0.05) income low income (men r = -0.80, P<0.001, women r = -0.76, P<0.001), median family income (men r = 0.79, P = 0.06, women r = 0.76, P<0.001) and ICP per capita (men r = 0.73, P<0.001, women r = 0.68, P<0.001) throughout the study period.ConclusionThe increase of income and reducing inequality may partially explain the increased occurrence of colorectal cancer and this is possibly due to differential access to food recognized as a risk factor, such as red meat and high in fat. It is important therefore to assess the priority of public health programs addressing nutrition in countries of intermediate economy, as is the case of Brazil.

Socioeconomic development and colorectal cancer mortality in a state of the Brazilian Legal Amazon from 2005 to 2016

“…A similar result was found in the study by Guimarães et al 27 , who estimated the correlation between the average per capita income and the CRCMR in Brazil between 2001 and 2009. There was a reduction in the trend of poverty and inequality in income and growth of GDP per capita, family income and standardized CRCMR in Brazil.…”

“…Other behaviors such as smoking and sedentarism also increase the risk of developing this cancer. Studies indicate that these habits are directly associated with economic development, which ends up leading people to a western-like lifestyle 5,26,27 .…”

Socioeconomic differentials and mortality from colorectal cancer in large cities in Brazil

“…In Brazil, Guimarães and his collaborators in a study to estimate the correlation between median per capita income and mortality rate because of colorectal cancer during the period from 2001–2009 observed that there is a statistically significant positive correlation between the more developed regions and the mortality rates because of colon cancer for both sexes [24]. …”
