BMC Public Health:研究显示低血压与自杀念头可能存在关联

2018-03-03 张章 科学网

近日,《BMC公共卫生》发表的一个研究显示,低血压可能与自杀的念头/想法相关。韩国首尔大学研究者发现,收缩压低于100 mmHG(毫米汞柱)的人产生自杀念头的几率比血压正常者高。

近日,《BMC公共卫生》发表的一个研究显示,低血压可能与自杀的念头/想法相关。韩国首尔大学研究者发现,收缩压低于100 mmHG(毫米汞柱)的人产生自杀念头的几率比血压正常者高。

Sung-il Cho说:“尽管之前有研究表明低血压和包括抑郁、焦虑在内的神经心理学问题有关,但还没有人研究过低血压和自杀念头之间的关联,我们的发现表明,低血压相关的健康指标可能需要被纳入心理健康评估的范畴。”

研究人员使用了10708名19至101岁韩国人的数据研究低血压和自杀念头的关系,这其中有2569人(24%)低血压(低于100mmHG),1199人(11.2%)有自杀念头。有自杀念头的女性多于男性,年纪最大的人群出现自杀念头的比例最高。这些数据来自2010-2013年的韩国国家健康与营养调查,这是一个全国性的大规模调查,旨在了解韩国人的健康和营养状况。

对不同水平的低血压人群进行分析后,研究人员发现血压越低的组别,有自杀念头的比例越高:在收缩压低于100 mmHG的参与者中,12.5%的有自杀念头,而在收缩压低于95 mmHG的人中,13.7%的有自杀念头,在收缩压低于90 mmHG 的人中,这个数字是16.6%,而血压正常的参与者中,只有10.8%有自杀的念头。

结果显示,低血压组别中较高的自杀倾向表明这两者之间可能存在关联。高血压前期和高血压与自杀念头之间则没有明显的关联。

Sung-ilCho说:“虽然高血压前期可能是导致心血管疾病的一个危险因素,应该予以干预,但它似乎对心理健康没有负面影响。该研究挑战了通常认为低血压对心理健康更有益的看法。”

但作者提醒,由于本研究是横向研究,因此无法得出因果性的结论,也不能排除低血压与自杀念头之间存在双向关联。研究中使用的调查数据为参与者的自我报告,因此有可能存在偏差。而且,研究只使用了收缩压作为低血压的标准,之后的研究还需要探索自杀念头和舒张压之间的关系。而血压和自杀关联背后的生物学原理,也需要进一步研究确定。

妊娠子宫对下腔静脉的压迫和腰麻对交感神经的阻滞引起血管扩张是剖宫产术中腰麻后低血压的主要机制。手指灌注指数(PI)可通过反映基础血管张力从而预测腰麻后低血压,但不能反映下腔静脉的受压情况。本研究主要探讨腰麻前后足趾PI的变化是否可以预测腰麻后低血压的发生,以及是否可以反映妊娠子宫对下腔静脉的压迫情况。
