| 12 | Trends and predictions for gastric cancer mortality in Brazil显示文摘AIM: To analyze the effect of age-period and birth cohort on gastric cancer mortality, in Brazil and across its five geographic regions, by sex, in the population over 20 years of age, as well as make projections for the period 2010-2029.METHODS: An ecological study is presented herein,which distributed gastric cancer-related deaths in Brazil and its geographic regions. The effects of ageperiod and birth cohort were calculated by the Poisson regression model and projections were made with the age-period-cohort model in the statistical program R. RESULTS: Progressive reduction of mortality rates was observed in the 1980's, and then higher and lower mortality rates were verified in the 2000's, for both sexes, in Brazil and for the South, Southeast and Midwest regions. A progressive decrease in mortality rates was observed for the Northeast(both sexes) and North(men only) regions within the period 1995-1999, followed by rising rates. CONCLUSION: Regional differences were demonstrated in the mortality rates for gastric cancer in Brazil, and the least developed regions of the country will present increases in projected mortality rates. | Angela Carolina Brandao de Souza Giusti Pétala Tuani Candido de Oliveira Salvador Juliano dos Santos Karina Cardoso Meira Amanda Rodrigues Camacho Raphael Mendonca Guimaraes Dyego LB Souza | 2016 | World Journal of Gastroenterology2016，22，28： | 0 |
