One of the most important components of suicide prevention strategies is to target people who repeat self-harm as they are a high risk group. However, there is some evidence that the incidence of repeat self-harm is lower in Asia than in the West. The objective of this study was to investigate the prevalence of previous self-harm among a consecutive series of self-harm patients presenting to hospitals in rural Sri Lanka.
Six hundred and ninety-eight self-poisoning patients presenting to medical wards at two hospitals in Sri Lanka were interviewed about their previous episodes of self-harm.
Sixty-one (8.7%, 95% CI 6.7-11%) patients reported at least one previous episode of self-harm [37 (10.7%) male, 24 (6.8%) female]; only 19 (2.7%, 95% CI 1.6-4.2%) patients had made more than one previous attempt.
The low prevalence of previous self-harm is consistent with previous Asian research and is considerably lower than that seen in the West. Explanations for these low levels of repeat self-harm require investigation. Our data indicate that a focus on the aftercare of those who attempt suicide in Sri Lanka may have a smaller impact on suicide incidence than may be possible in the West.
自杀预防策略中最重要的组成部分之一是针对重复自伤的人群，因为他们是高风险群体。然而，有证据表明，亚洲的重复自伤发生率低于西方。本研究的目的是调查斯里兰卡农村医院就诊的连续系列自伤患者中以前自伤的发生率。
对斯里兰卡两家医院的 698 名服毒自杀者进行了采访，询问他们以前的自伤情况。
61 名（8.7%，95%CI6.7-11%）患者报告至少有一次以前的自伤[37 名（10.7%）男性，24 名（6.8%）女性]；只有 19 名（2.7%，95%CI1.6-4.2%）患者以前有过多次尝试。
以前自伤的低发生率与以前的亚洲研究一致，大大低于西方的发生率。需要对这些低水平的重复自伤进行解释。我们的数据表明，在斯里兰卡，关注自杀未遂者的康复可能对自杀发生率的影响比在西方可能要小。
