Diet and mortality from common cancers in Brazil: an ecological study

Abstract

A prospective ecological evaluation of mortality from common malignancies with dietary risk factors and alcohol consumption was carried out among 10 state capitals of Brazil. Regression analysis was used to examine the association of dietary intake with mortality rates of the most common cancers among adults age 30 years and older. Age-adjusted cancer mortality rates varied 2.4 to 3.3 fold across the state capitals. A positive relationship was observed between energy intake and colon, lung, and esophageal cancer (p <0.05). Stomach cancer was associated with consumption of eggs (p=0.04); and negatively associated with consumption of high fiber foods, fruits, and vitamin A and C (p <0,05); câncer de estômago associou-se positivamente com ovos (p=0,04) e, negativamente, com o consumo de fibras, frutas e vitaminas A e C (p
