The distinctive epidemiologic profile of suicide in China, with notably high rates among rural young adult females, invites examination of possible underlying risk factors. Although there are accumulating data regarding the epidemiology of suicide among youth and young adults in China, there are meager data on suicidal ideation and attempts despite its importance.
Our study in 2005-06 sought to identify all potentially suitable rural participants, aged 16-34 years, from 10 representative villages in rural Sichuan Province. We conducted structured interviews regarding a range of socio-demographic characteristics and suicidal morbidity.
1654 of a potential 3008 participants participated; lifetime and one-year prevalence were: suicidal ideation (18.8% and 5.2%), serious ideation (8.6% and 2.3%), planning (5.8% and 1.5%), and attempt (2.7% and 0.5%). Comparisons among strata of socio-demographic characteristics showed more prevalent suicidal ideation associated with: female gender, lower education, poorer financial perception, greater rurality of residence, and marital status of "never married" or "others". Suicidal attempt was associated with: female gender and a marital status of "others".
The study was carried out in one province and caution is required when considering other rural regions of China. There were a substantial number of unapproachable subjects because of their migrant work at distant sites.
Our results revealed an apparently higher prevalence for suicide ideation and planning compared with residents of other countries, but a lower prevalence for attempts. These data suggests that the relatively high rate of suicide in rural China reflects an elevated case fatality ratio due to chosen methods. The results also revealed unique patterns for correlates with the occurrence of ideation and attempts.
中国自杀的独特流行病学特征,尤其是农村年轻成年女性的自杀率极高,这使得人们有必要对潜在的风险因素进行探讨。尽管目前中国有越来越多关于青年和年轻成年人自杀的流行病学数据,但自杀意念和自杀未遂的相关数据却很少,尽管后者很重要。
我们在 2005-06 年的研究试图从四川省农村的 10 个代表性村庄中确定所有可能的农村潜在参与者,年龄在 16-34 岁之间。我们进行了结构化访谈,以了解一系列社会人口学特征和自杀发病率。
在潜在的 3008 名参与者中,有 1654 人参与了研究;终身和一年的患病率分别为:自杀意念(18.8%和 5.2%)、严重自杀意念(8.6%和 2.3%)、自杀计划(5.8%和 1.5%)和自杀未遂(2.7%和 0.5%)。对社会人口学特征各层的比较显示,更多的自杀意念与以下因素相关:女性性别、较低的教育程度、较差的经济状况、更偏远的居住地和“未婚”或“其他”的婚姻状况。自杀未遂与女性性别和“其他”的婚姻状况相关。
该研究仅在一个省进行,在考虑中国其他农村地区时需要谨慎。由于研究对象在遥远的地方工作,有相当数量的研究对象无法接近。
我们的研究结果显示,中国农村地区的自杀意念和自杀计划发生率明显高于其他国家,但自杀未遂的发生率较低。这些数据表明,中国农村地区相对较高的自杀率反映了由于选择的方法而导致的病死率相对较高。研究结果还揭示了与意念和未遂发生相关的独特模式。
