過去十年來台灣地區自殺率急速增加,因此本研究以年齡、年代及世代三個因素探討台灣地區自1976-2001年自殺率變動模式。本研究採用圖型分析及布瓦松迴歸模型對年齡、年代及世代三個效應進行評估。相對風險效應顯示,風險隨年齡增加而提高;年代效應自1976到1986年爲上升趨勢,之後開始下降,而後自1991年又開始上升;較年長的世代則較年輕世代爲高。自殺率隨年齡的增加而提高。年代效應則顯示自殺率隨不同年代而有所不同。世代效應則隨不同的年齡及年代而有所不同。
The suicide rate of Taiwan have been increased rapidly in the past decade. We examine the trend of suicide rates associated with age, year and cohort effects from 1976 to 2001 by using graphical methods and Poisson regression. From the study, we found the suicide rates increased as the age got older. As to the years of suicide, the trend rose from 1976 to 1986, and was declining after 1986. Starting 1991, the trend went up again. As to the age-specific group, the older cohort tended to have higher suicide risks than younger cohorts.
