The regional distribution of completed suicide was analyzed in 19 regions of France for the years 1975 and 1983. The regional distributions of environmental variables (ambient temperature, sunlight duration, and precipitation) and of sociological factors (social cohesion, socioeconomic status, status of women, and social support) were then correlated using Pearson coefficients, stepwise regression analysis, and partial correlations. Our main finding is that environmental factors such as ambient temperature may play a role in the regional distribution of completed suicide in France. Both the stepwise regression analysis and the controlled regression analysis revealed that, among all the variables studied (environmental and sociological), the main factors affecting the regional distribution of suicide were ambient temperature and sunlight duration. To our knowledge, this is the first detailed study demonstrating a clear relationship between environmental variables and suicidal behavior. The finding may be consistent with the recent description of forms of affective disorders occurring in relationship to environmental factors.
对法国19个地区1975年和1983年的自杀既遂情况进行了区域分布分析。然后，使用皮尔逊系数、逐步回归分析和偏相关分析，将环境变量（环境温度、日照时长和降水量）以及社会学因素（社会凝聚力、社会经济地位、女性地位和社会支持）的区域分布进行关联分析。我们的主要发现是，环境因素如环境温度可能在法国自杀既遂的区域分布中发挥作用。逐步回归分析和控制回归分析均显示，在所有研究变量（环境和社会学变量）中，影响自杀区域分布的主要因素是环境温度和日照时长。据我们所知，这是第一项详细研究，证明了环境变量与自杀行为之间存在明确关系。这一发现可能与近期对与环境因素相关的情感障碍形式的描述一致。
