Description
Summary:Context Several 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. Objective The 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. Methods We obtained data on income inequality (Gini index), population with low incomes (&#189; 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. Results There 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. Conclusion The 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.<br> Contexto Diversos estudos internacionais t&#234;m observado uma correla&#231;&#227;o entre a melhora dos indicadores sociodemogr&#225;ficos e as taxas de incid&#234;ncia e mortalidade por c&#226;ncer de c&#243;lon e reto. Objetivo O objetivo do presente estudo &#233; estimar a correla&#231;&#227;o entre renda m&#233;dia per capita e a taxa de mortalidade por c&#226;ncer colorretal no Brasil entre 2001 e 2009. M&#233;todos Obteve-se os dados de desigualdade de renda (&#237;ndice de Gini), popula&#231;&#227;o que vive com baixa renda (inferir a &#189; sal&#225;rio m&#237;nimo/m&#234;s), renda m&#233;dia familiar, PIB per capita e taxa de mortalidade por c&#226;ncer de c&#243;lon e reto entre 2001 e 2009 atrav&#233;s do DATASUS. A an&#225;lise de tend&#234;ncia foi realizada atrav&#233;s do m&#233;todo de regress&#227;o linear, e a correla&#231;&#227;o entre as vari&#225;veis atrav&#233;s do coeficiente de correla&#231;&#227;o de Pearson. Resultados Observou-se tend&#234;ncia ao decl&#237;nio da pobreza e da desigualdade de renda, e incremento no PIB per capita e na renda m&#233;dia familiar e na taxa de mortalidade padronizada de c&#226;ncer de c&#243;lon e reto no Brasil. Observou-se, ainda, correla&#231;&#227;o fortemente positiva entre a mortalidade por este s&#237;tio de c&#226;ncer e desigualdade (homens r = -0,30, P = 0,06; mulheres r = -0,33, P = 0,05) de renda baixa renda(homens r = -0,80, P<0,001; mulheres r = -0,76, P<0,001), renda m&#233;dia familiar (homens r = 0,79, p = 0,06; mulheres r = 0,76, P<0,001) e PIB per capita (homens r = 0,73, P<0,001; mulheres r = 0,68, P<0,001) em todo o per&#237;odo estudado. Conclus&#227;o O incremento da renda e a redu&#231;&#227;o da desigualdade podem parcialmente explicar o aumento da ocorr&#234;ncia do c&#226;ncer de c&#243;lon e reto e isso possivelmente se deve ao acesso diferenciado a alimentos reconhecidos como fator de risco, como carne vermelha e os ricos em gordura. &#201; importante, portanto, avaliar como prioridade dos programas de sa&#250;de p&#250;blica a abordagem nutricional em pa&#237;ses de economia intermedi&#225;ria, como &#233; o caso do Brasil.
