摘要

目標：建立台灣酒精性疾病死亡之地理分佈與空間聚集型態，並探討男女不同性別之死亡風險聚集差異。方法：採用台灣地區2002－2006年的全國死亡診斷登記系統之電腦資料檔，依據ICD-9CM進行酒精性疾病死亡分類，總計台灣本島349鄉鎮市區有30,669之15歲（含）以上死亡人口，以2002年為標準人口分別計算男女性酒精性疾病標準死亡比（SMR）及進行Global G與Local Gi*空間統計量分析死亡風險之空間聚集分佈。結果：酒精性疾病死亡主要風險族群為男性（佔68%），男女性在各鄉鎮市區年死亡中位數分別為8.8與4.5人。在地理分佈方面，高風險空間聚集區域多位於非都市之偏遠鄉鎮，其中女性死亡風險顯著較高且不同於男性空間聚集之區域，係以宜蘭縣南澳鄉及以雲林縣台西鄉為中心的兩個區域。結論：本研究驗證台灣酒精性疾病死亡風險存在性別與地理城鄉聚集之差異，透過這些地域的鑑別，未來輔以相關社會人口資料變項的分析，將有助於獲得影響男女酒精性疾病死亡風險因子的進一步釐清。

Objectives: This research analyzed the geographical distribution and spatial clustering of alcohol-attributed disease mortality in Taiwan, and determined the gender differences in this clustering. Methods: Using 2002-2006 data from the national death-diagnosis registration system and categorizing alcohol-attributed disease mortality by ICD-9CM diagnoses, we calculated the number of alcohol-attributed, disease related deaths of those aged 15 and older to be 30,669 in 349 townships on Taiwan's main island. This research utilized 2002 data as the standardized population to calculate the alcohol-attributed disease standard mortality ratio (SMR), and applied the SMR to Global G and Local Gi* statistics to determine the spatial clustering of deaths by geographical distribution. Results: Sixty-eight percent of alcohol-attributed disease related deaths were males, and the median numbers of males and females were 8.8 and 4.5, respectively. From the results of spatial analysis of geographical distribution, statistically significant highnumber pockets tended to cluster in remote townships. There were more females than males in two independent pockets (NanAo and Taisi townships). Conclusions: Results from this research demonstrated that alcohol-attributed disease mortality did show gender and spatial clustering differences in Taiwan. By indentifying the high risk areas and analyzing related demographic variables, we may be able to provide further insight into the alcohol-attributed disease mortality factors for men and women in Taiwan.
