Patterns of lung cancer mortality in 23 countries: Application of the Age-Period-Cohort model

摘要: Smoking habits do not seem to be the main explanation of epidemiological characteristics female lung cancer mortality in Asian countries. However, countries are often excluded from studies geographical differences trends for mortality. We thus examined 1971 1995 among men and women 23 countries, including four Asia. International national data were used analyze both sexes. Age-standardized rates (ASMR) analyzed five consecutive five-year periods each age group range 30 79. The age-period-cohort (APC) model was estimate period effect (adjusted cohort effects) cancer. sex ratio ASMR lower while smoking prevalence higher mean values Taiwan, Hong Kong, Singapore, Japan 5-year 2.10, 2.39, 3.07, 3.55, respectively. These only remained quite constant over period, but also than seen western effect, as derived APC model, could classified into seven patterns. Period effects using Four have a relatively low high prevalence. Factors other might important, especially
