Trends in mortality from road traffic injuries in South Korea, 1983–2017: Joinpoint regression and age-period-cohort analyses

摘要: Although mortality trends can be influenced by different ages, periods, and cohorts, few studies have demonstrated the age-period-cohort (APC) effect on road traffic injury (RTI) mortality. Moreover, APC effects in Korea never been documented despite high rates from RTIs. This study aimed to describe RTIs examine RTI Korea. Using national death certificate census mid-year population estimates data during 1983-2017, age-standardized were analyzed using Joinpoint regression. Intrinsic estimator regression models used estimate Consistent with trend period effects, increased sharply economic growth 1980s, decelerated after implementation of safety policies early 1990s, plummeted owing 1997-1998 financial crisis, gradually decreased 2000s. A J-shaped age indicated that relative risk surged people aged ≥65 years. Educational expansion mid-1950s turned an increasing birth cohort into a continuously decreasing peaking around 1938-1943 cohorts. The was relatively among Korean Generation Y, i.e., those born 1978-1983. affected diverse socioeconomic changes through effects. Despite recent favorable trend, remains high, especially older people. Road address burden require further improvement.
