Suicide prevention in the elderly is a major public health priority worldwide and in Korea in particular. We investigated the one-month-point prevalence and factors related to suicidality for suicidal behaviors in elderly Koreans.
A simple random sample (N=1588) was drawn from the residential roster of 14,051 Koreans aged 60 years or older who were residents of Osan in February 2010. All subjects were invited to participate in the survey through door-to-door home visits, and the response rate was 59.8%.
The age- and gender-standardized prevalence rates of lifetime suicide attempts, current suicidal ideation without a plan or attempt, and current suicidal ideation with a plan or attempt were estimated at 9.2%, 19.6%, and 2.24%. The prevalence of suicidal ideation without a plan or attempt was higher in women and less-educated individuals and increased with advancing age, whereas the prevalence of suicidal ideation with a plan or attempt was higher in more-educated individuals, was not differentiated by gender, increased until age 70, and then decreased thereafter. The factors related to suicidal ideation differed by the presence of a suicide plan or attempt.
Depressive elders in their 70s who have recently developed suicidal ideation would be a prime target for suicide intervention programs.
The sample was regional, although the suicide rate in Osan was comparable to the average suicide rate in Korea.
预防老年人自杀是全球，特别是韩国的一项重大公共卫生重点。我们调查了韩国老年人自杀行为的一个月时点发生率和与自杀意念相关的因素。
2010 年 2 月，从居住在韩国 Osan 的 14051 名 60 岁及以上老年人的居民名单中抽取了一个简单随机样本（N=1588）。所有被试者都通过挨家挨户的家访被邀请参加调查，应答率为 59.8%。
终生自杀未遂、当前无计划或尝试自杀意念以及当前有计划或尝试自杀意念的年龄和性别标准化发生率分别估计为 9.2%、19.6%和 2.24%。女性和受教育程度较低的个体自杀意念无计划或尝试的发生率较高，且随年龄增长而增加，而受教育程度较高的个体自杀意念有计划或尝试的发生率较高，不受性别差异影响，直到 70 岁时增加，然后此后下降。与自杀意念相关的因素因是否存在自杀计划或尝试而有所不同。
最近出现自杀意念的 70 多岁抑郁老年人将是自杀干预计划的主要目标。
尽管 Osan 的自杀率与韩国的平均自杀率相当，但该样本是区域性的。
