  1. Time trend and age-period-cohort effects on gastric cancer incidence in Zaragoza and Navarre, Spain.

    Article - En anglais

    Study objective-To describe time trends in gastric cancer incidence in Zaragoza and Navarre, and to investigate time period and birth cohort as determinants of such trends.

    Design-Cases from two registries were grouped into five year intervals and the following were calculated : age specific and sex specific incidence rates, age adjusted incidence rates, cumulative rates, and the male to female ratio.

    Log linear models including age, period of diagnosis, and birth cohort were fitted.

    Setting-The Zaragoza Cancer Registry covers the province of Zaragoza, which has a population of 824776 (403 755 men and 421021 women).

    The Navarre Cancer Registry covers the province of Navarre which has 512 512 inhabitants (254 786 men and 257 726 women).

    In both cases population figures were based on the 1986 census.

    Patients-These comprised incident cases of gastric cancer reported to the Zaragoza Cancer Registry in 1963-87 and to the Navarre Cancer Registry in 1973-87.

    Main results-Navarre registered higher adjusted and cumulative rates than Zaragoza for both sexes.

    In both provinces, there were relative declines in the rates for men and women of 3% and 4% respectively per year.

    In Zaragoza, the risk of developing stomach cancer fell in generations born between 1888 and 1933, and rose in subsequent birth cohorts in both sexes, while in Navarre the cohort effect showed an approximately linear decrease in risk for both sexes. (...)
