Diet and gastric cancer in Portugal : a multivariate model.
Diet and gastric cancer mortality in Portugal was studied using a multivariate ecological model.
The factors investigated over 18 districts were the relationship between gastric cancer mortality (1994-96), dietary habits, and socio-economic factors (1980-81).
Mortality geographical pattern was established using age-standardized mortality rates, per capita dietary consumption of foodstuffs and nutrients was obtained from the National Alimentary Survey (1980-81), and data on socio-economic factors from the 1981 National Census.
Pearson correlation coefficients and simple and multiple linear regression models were used.
The mortality geographical pattern resembled a north-south gradient, and dietary habits and socio-economic factors had great variability throughout the country.
The highest negative correlation coefficients between dietary consumption and gastric cancer mortality were obtained for vegetables, fruit, vitamin A and carotene consumption, and the highest positive coefficients were for rice, wine and carbohydrate consumption.
No significant correlations were obtained for socio-economic factors.
In multiple regression analysis, vegetable and rice consumption could account for 79% of the gastric cancer mortality variability for males, and vegetable and meat consumption could account for 69% of this variability for females.
Interestingly, meat consumption was found to be protective. (...)
