Among the Korean elderly (those 65 years of age and older), the suicide rate is 80.3/100 000 people, which is ten times higher than the Organization for Economic Cooperation and Development average. Because South Korea is rapidly becoming an aging population, this high elderly suicidal rate will only get worse. Although the size of the elderly suicide problem is quite large, previous research in South Korea has surveyed restricted areas and not the entire country. Even though the factors that affect elderly suicide are complicated, there has been little research into these influencing factors. Thus, this research uses the national survey data (Community Health Survey) that was obtained in 2009. Additionally, we analyze factors affecting elderly suicidal ideation and attempts as well as the paths of these effects.
Community Health Survey data obtained by the Korea Centers for Disease Control and Prevention in 2009 was used for this study. We additionally examined the factors that affect suicide with chi-squared tests, t-tests, Pearson's correlation test, and path analysis.
Depressive symptoms and suicidal ideation are the only factors that directly affect suicidal attempts. Demographic, behavioral, and physical activity factors have indirect effects on suicidal attempts.
Depression has the strongest influence on suicidal ideation and attempts. Demographic, behavioral, and physical activity factors affect suicidal attempts mostly through depressive symptoms. In addition, there is a path that suggests that demographic, behavioral, and physical activity factors affect suicidal attempts not through depression symptoms but only through suicidal ideation. This means that the elderly who do not have depression symptoms attempt suicide according to their own situations and characteristics.
在韩国老年人(65岁及以上)中,自杀率为每10万人80.3例,这比经济合作与发展组织的平均水平高出十倍。由于韩国正迅速步入老龄化社会,这种高老年自杀率只会愈发严重。尽管老年自杀问题规模相当大,但韩国此前的研究仅调查了有限区域,而非全国范围。即便影响老年自杀的因素错综复杂,但对这些影响因素的研究却很少。因此,本研究使用了2009年获得的全国调查数据(社区健康调查)。此外,我们分析了影响老年人自杀意念和自杀未遂的因素以及这些影响的路径。
本研究使用了韩国疾病控制与预防中心2009年获得的社区健康调查数据。我们还通过卡方检验、t检验、皮尔逊相关检验和路径分析来研究影响自杀的因素。
抑郁症状和自杀意念是直接影响自杀未遂的唯一因素。人口统计学、行为和身体活动因素对自杀未遂有间接影响。
抑郁对自杀意念和自杀未遂的影响最为强烈。人口统计学、行为和身体活动因素大多通过抑郁症状影响自杀未遂。此外,有一条路径表明,人口统计学、行为和身体活动因素并非通过抑郁症状,而是仅通过自杀意念影响自杀未遂。这意味着没有抑郁症状的老年人会根据自身情况和特点尝试自杀。
