Incidence of colorectal cancer and influence of dietary habits in fifteen European countries from 1971 to 2002

ABSTRACT

Objective This study aimed to analyze the incidence of colorectal cancer in 15 European countries in recent decades and the relationship between the incidence found and changes in dietary habits .Methods Pearson's or Spearman's correlation coefficients were calculated by comparing incidence rates obtained from the International Agency for Research on Cancer for 1971-2002 with data on per capita consumption obtained from the Food and Agriculture Organization of the United Nations using 10-year delay intervals. Results Incidence rates increased in all countries except France in men and except Austria, Denmark, England and France in women. Of the dietary variables considered, there were marked increasing trends (linear regression coefficient, R ≥0.5) in red meat consumption in Germany (R = 0.9), Austria (R = 0.7), Finland (R = 0.8), Italy (R = 0.9), Poland (R = 0.5), Spain (R = 2.1), Sweden (R = 0.6), and the Netherlands (R = 0.7).Conclusions Changes in dietary habits may be consistent with the observed trends in the incidence of colorectal cancer in the distinct European countries (AU)

RESUMEN

Introducción Este estudio analiza la incidencia de cáncer colorrectal en 15 países europeos en las últimas décadas y su relación con cambios en los hábitos alimenticios. Métodos Coeficientes de correlación de Pearson/Spearman calculados comparando las tasas de incidencia obtenidas de International Agency for Research on Cancer durante 1971-2002 con los consumos per cápita obtenidos de Food and Agriculture Organization con intervalos de retardo de 10 años. Resultados Las tasas de incidencia aumentan en todos los países, excepto en Francia, en los hombres, y en Austria, Dinamarca, Inglaterra y Francia en las mujeres. De las variables de la dieta estudiadas, hay marcadas tendencias crecientes (coeficiente de regresión lineal, R ≥0,5) para carne roja en Alemania (R = 0,9), Austria (R = 0,7), España (R = 2,1), Finlandia (R = 0,8), Italia (R = 0,9), Países Bajos (R = 0,7), Polonia (R = 0,5) y Suecia (R = 0,6).Conclusiones Los cambios en los hábitos dietéticos pueden ser concordantes con las tendencias de la incidencia de cáncer colorrectal observadas en diferentes países (AU)
