摘要

目標：將台灣地區鄉鎮重新分類成十一區，再進行死亡率地理變異分析。方法：以1992至2001年男性胰臟癌為例，進行傳統五大行政區域及新的分類法，其直接年齡標準化死亡率值的比較。再以肝癌及肺癌為例，進行新分類方法的死亡率地理變異分析。結果：五大行政區胰臟癌的直接年齡標準化死亡率值，與台灣地區相比均未達統計顯著差異。相反地，新分類法中，可看到客家地區的死亡率相對較低。其中客家地區男性胰臟癌每十萬人年3.64人(95%信賴區間為3.30~3.98人)，顯著低於台灣地區的4.06人；客家地區男、女性的肝癌死亡率分別為每十萬人年27.16人(95%信賴區間為26.20~28.12人)、9.39人(95%信賴區間為8.80~9.98人)，分別顯著低於台灣地區的36.72及12.07人；肺癌死亡率男性每十萬人年25.83人(95%信賴區間為24.94~26.73人)及女性每十萬人年11.80人(95%信賴區間為11.14~12.47人)，也顯著分別低於台灣地區的31.35及14.33人。結論：新分類法較能看出死亡率地理變異的差異性。

Objective: To examine geographic variations in mortality rates by dividing Taiwan into 11 newly designated areas.
Methods: From 1992 to 2001, we compared geographic variations in age-standardized mortality rates in Taiwan between the traditional grouping of five administrative areas and a new grouping pattern of eleven areas. Variations in mortality rates of pancreatic cancer in males and of liver and lung cancer mortality rates in males and females were compared.
Results: There were no statistical differences in age-standardized mortality rates of pancreatic cancer in males between any one of the five traditional administrative areas and Taiwan overall. However, in the newly designated 11 areas, mortality rate of pancreatic cancer was significantly lower in the Hakka area: 3.64 per 100,000 person years (95% confidence interval (CI) = 3.30 ~ 3.98) compared with 4.06 per 100,000 person years for Taiwan overall. Mortality rates of liver cancer in Hakka area males and females were 27.16 (95% CI=24.94~26.73) and 11.80 (95% CI=11.14~12.47) per 100,000 person years, respectively. These were also lower than the comparable rate for Taiwanese overall.
Conclusions: The new 11 area grouping method was more effective than the traditional 5 area method in studying characteristics of cancer mortality rates in Taiwan.
