INTRODUCTION
The purpose of the present study was to explore the relationship between the secular trend of the suicide rate and the socio-economic, media, and climatic factors in Taiwan during 1976-2009.
METHODS
The yearly suicide death rate, socio-economic (spouseless population, aged population, labor participation rate, unemployment rate, and gross national production), media (newspapers, television sets, and personal computer) densities, and climatic (temperature, rainfall, and sunshine) factors were gathered. Pearson's correlation coefficients between variables were calculated, and stepwise multiple regression analysis was conducted.
RESULTS
Percentage of the spouseless and elderly population, labor participation rate, unemployment rate, and densities of newspapers and personal computer were significantly associated with suicide rate. Multiple regression chose spouseless population, labor participation rate, and unemployment rate to explain 96.1% of the variance of the suicide rate (F((3,22))=178.996, p=0.000).
CONCLUSIONS
Socio-economic factors are important for the secular trend of suicide, while medium densities also play some roles.
简介
本研究旨在探讨 1976 年至 2009 年期间台湾地区自杀率的长期变化趋势与社会经济、媒体和气候因素之间的关系。
方法
收集了每年的自杀死亡率、社会经济因素（丧偶人口、老年人口、劳动参与率、失业率和国民生产总值）、媒体（报纸、电视机和个人电脑）密度以及气候（温度、降雨量和日照）因素。计算了变量之间的 Pearson 相关系数，并进行了逐步多元回归分析。
结果
丧偶人口和老年人口的比例、劳动参与率、失业率以及报纸和个人电脑的密度与自杀率显著相关。多元回归选择丧偶人口、劳动参与率和失业率来解释自杀率变化的 96.1%（F((3,22))=178.996，p=0.000）。
结论
社会经济因素对自杀的长期变化趋势很重要，而媒体密度也起到了一定的作用。
