Trends and characteristics of gastric cancer mortality in China,2006-2012

ObjectiveTo analyze distribution features and variation trends of gastric cancer mortality in China,2006-2012.MethodsThe data on gastric cancer mortality from 2006 to 2012 were collected from National Disease Surveillance System and analyzed to estimate gastric cancer mortality by gender,urban and rural areas,and geographic locations.The changes in standardized mortality of gastric cancer were described and the annual change percentages in age-specific standardized mortality were estimated using log linear regression method.ResultsIn China,the standardized gastric cancer mortality showed a downward trend in 2006-2012.In 2006,the gastric cancer standardized mortality was 31.84/100 000 among males and 13.32/100 000 among females; whereas in 2012,the standardized gastric cancer mortality of males and females reduced to 26.51/100 000 and 10.95/100 000,respectively.The annual decrease rate of gastric cancer mortality was 3.73% for male and 4.40% for female,and the annual decrease rate was the highest among females in rural areas(4.69%) and the rate was 3.82% among rural males.The decrease rate was the lowest among urban females(3.34%).ConclusionThe gastric cancer mortality presented a downward trend,especially in the rural areas,from 2006 to 2012 in China.
