South Korea has the highest suicide rate among countries in the Organisation for Economic Co-operation and Development (OECD), with a rising trend that contrasts with the trend in most other OECD countries. This study assessed differential associations of socio-demographic factors with suicidal ideation in South Korea. We used five waves of data from the 2010 Korea National Health and Nutrition Examination Survey. Study subjects included 5803 men and women aged >25 years. We analysed weighted percentages with consideration of the complex survey sample design and unequal weights. Surveylogistic regressions were applied. Protective effects against suicidal ideation were found for higher household income, higher educational attainment, and being married. Functional limitations and depressive symptoms were risk factors for suicidal ideation. However, these significant factors may exert different effects on vulnerability for suicidal ideation among different genders and age groups. Thus, household income was mainly protective for women and subjects aged 25-44 years, and educational attainment was protective for individuals aged >65 years. Our findings suggest the need for extended social protection policies for the less privileged population and special strategies for different groups.
韩国是经合组织（OECD）成员国中自杀率最高的国家，且自杀趋势呈上升趋势，与大多数其他经合组织国家的趋势形成鲜明对比。本研究评估了社会人口因素与韩国自杀意念的差异关联。我们使用了 2010 年韩国国家健康和营养检查调查的五波数据。研究对象包括 5803 名年龄>25 岁的男性和女性。我们分析了加权百分比，考虑了复杂的调查样本设计和不等权重。应用了 surveylogistic 回归。较高的家庭收入、较高的教育程度和已婚状态对自杀意念有保护作用。功能障碍和抑郁症状是自杀意念的危险因素。然而，这些显著因素可能对不同性别和年龄组的自杀意念易感性产生不同的影响。因此，家庭收入主要对 25-44 岁的女性和>65 岁的个体起保护作用，而教育程度对>65 岁的个体起保护作用。我们的研究结果表明，需要为弱势群体制定更广泛的社会保护政策，并为不同群体制定特殊策略。
