目的近年来，世界范围内农村地区自杀率高于城市地区。尽管农业活动是许多农村地区的一个关键特征，但根据所追求的农业类型，农村也可能具有不同的性质。然而，到目前为止，还没有研究考察自杀率和农业类型之间的潜在联系。方法在这项研究中，我们使用了1983-2007年日本市政当局自杀和特定产品农业产出的标准化死亡率(SMR)的年度时间序列数据来解释这一现象。考虑到时间序列数据的层次结构，我们进行了多水平线性回归分析，将分析限制在农业土地利用率较高的直辖市。结果多水平分析显示，无论是男性还是女性，畜牧业产量与自杀性SMR都呈正相关，女性之间的相关性更强，而农业作物产量与自杀SMR之间没有相关性。时间分析表明，在1983-2007年间，这种关联一直存在。结论本研究提出了依赖畜牧业的社区的行业和文化特征可能与自杀风险增加有关。
Objective In recent years, rural areas have reported higher suicide rates than urban areas worldwide. Although agricultural activity is a key characteristic of many rural areas, rurality may also have heterogeneous qualities based on the type of agriculture pursued. However, to date, no study has examined potential linkages between suicide rate and types of agriculture.Method In this study, we used 1983-2007 annual time-series data of the standardized mortality ratio (SMR) of suicide and product-specific agricultural outputs in Japanese municipalities to shed light on this phenomenon. We conducted a multilevel linear regression analysis, taking into account a hierarchical structure of the time-series data, limiting our analysis to municipalities where agricultural land use was high.Results Our multilevel analysis showed that the animal husbandry output was positively associated with suicide SMR in both women and men, with a stronger relationship among women, whereas no association was observed in agricultural crop output. Temporal analysis showed that the association could be observed consistently throughout the period between 1983 and 2007.Conclusions This study raises the possibility that the industrial and cultural characteristics of communities that rely on animal husbandry may be associated with an increased risk of suicide.
