目標：分析1991-2004年間臺北市社會經濟因子變遷與自殺率趨勢之關係。 方法：以獲自臺北市衛生局的資料，利用皮爾森相關分析法評估每年臺北市失業率、男女別勞動參與率、遷移率、離婚率、獨居率及貧窮率等社經因子與自殺率之關係係數。再以Cochrane-Orcutt迴歸分析評估各社經因子與性別、年齡分層自殺率之相關性。 結果：除了女性勞動參與率，本研究所評估之社經因子和總自殺率、男女別自殺率的皮爾森相關係數皆達統計上顯著意義 (P＜0.05)，且與男性自殺的相關性較高。Cochrane-Orcutt迴歸分析顯示社經因子和總自殺率、男女別自殺率之關係和皮爾森相關係數之結果一致，且發現男性自殺率與社經因子關係較女性強，而25-64歲青壯年族群之自殺率和社經因子的關聯性較其他年齡組高。 結論：社經因子與男性自殺率以及青壯年人口自殺率相關性高，提示完善之自殺防治計畫需與社會政策結合。

Objectives: To examine the relationship between socioeconomic factors and suicide mortality trends in Taipei City between 1991 and 2004. Methods: We used data obtained from the Taipei City Bureau of Health to assess Pearson's correlation coefficients between a series of socioeconomic factors, such as unemployment rates, social mobility rates, divorce rates, percentage of single person households, and poverty rates, and age-standardized suicide mortality rates. Cochrane-Orcutt regression was used to evaluate the relationship between socioeconomic factors and suicide death rates; the analysis was stratified by age and gender. Results: Pearson's correlation analysis showed that with the exception of the female labor force participation rate, all socioeconomic factors had a significant association with suicide death rates (P<0.05); the associations were stronger among males than females. The results obtained by Cochrane-Orcutt regression analysis were similar to the results derived from Pearson's correlation analysis. In addition, the relationships between socioeconomic factors and suicide rates were stronger among males than females, especially in the 25-64 year old age groups. Conclusions: Socioeconomic factors were powerful determinants of suicide among males, especially for middle-aged men. These finding suggest that implementation of appropriate social policies should be an integral part of an optimal suicide prevention program.
