    摘要
  • 摘要:
      目的   了解自杀未遂的影响因素和高危人群, 为自杀行为的干预提供科学依据。
      方法   采用病例对照研究, 对220对自杀未遂与对照进行分类树(CART)分析。
      结果   抑郁、情感冲突、给予了朋友精神支持、载脂蛋白E(ApoE-E), 2/3、低人均月收入、对现在生活不满意、吸烟、内向性格是自杀未遂的重要分类因素.高危人群有(1)情感冲突+抑郁; (2)情感冲突+无抑郁+较低人均月收入; (3)无情感冲突+抑郁+没有给予朋友精神支持; (4)无情感冲突+抑郁+给予朋友精神支持+ApoE-E2/3;(5)情感冲突+无抑郁+较高人均月收入+内向性格+不吸烟; (6)情感冲突+无抑郁+较高人均月收入+非内向性格+对现在生活不满意.所含病例数占总病例数的90%。
      结论   为降低自杀行为发生率, 临床医生及社区中相关人员应加强对该类人群的防治。

     

    Abstract:
      Objective   To understand important factors and high-risk populations of attempted suicide, and to provide the scientific base for the intervention of suicidal behaviour.
      Methods   220 suicide attempters and paired controls were analyzed by CART analysis.
      Results   The important classification factors of attempted suicide were depression, affective conflicts having given spirit support to friends, ApoE-E2/3, low monthly income perperson, dissat isfaction with life now, cigarette smoking, introversion character.The high-risk populations of attempted suicide were populations with: (1)affective conflicts+depression; (2)affective conflicts+no depression+low monthly income perperson; (3)no affective conflicts+depression+without given spirit support to friends; (4)no affective conflicts+depression+having given spirit support to friends+ApoE-2/3;(5)affective conflicts+no depression+compar atively high monthly income perperson; (6)affective conflicts+no depression +comparatively high monthly income perperson+not introversion character+dissatisfaction with life now.Cases in those populations took up 90% of all cases.
      Conclusion   Those populations should be paid attention to by clinic doctors and community workers.
