Suicide is a critical complication of psychiatric disorders. Physical activity has a positive effect on mental health; however, its effects on suicidal ideation have received little attention compared to other psychiatric symptoms.
Data were obtained from the Korea National Health and Nutrition Examination Survey 2014. Suicidal ideation was measured by the ninth item of the Patient Health Questionnaire-9. Physical activity was measured by the International Physical Activity Questionnaire (IPAQ) and categorized into three groups by activity level. Multiple logistic regression analysis was performed for the entire sample, men, and women. The following three models were used: Model 1 (adjusted for sociodemographic and health-related variables), Model 2 (additionally adjusted for subjective body image), and Model 3 (additionally adjusted for diagnosed depression).
Compared to the low IPAQ group, the moderate IPAQ group was significantly associated with decreased suicidal ideation in Model 3 for the entire sample (OR, 0.733; 95% CI, 0.538-0.999) and in all models for women. However, the high IPAQ group showed no significant association. None of the IPAQ groups showed significant associations in men.
This is a cross-sectional study. Therefore, the direction of causality cannot be determined. This study also investigated suicidal ideation over the past two weeks, which may be inconsistent with studies conducted over the past year.
The beneficial relationship between physical activity and suicidal ideation is weaker in men and individuals with high activity levels. Detailed guidelines on physical activity according to gender and activity level are recommended.
自杀是精神障碍的一个严重并发症。身体活动对心理健康有积极影响；然而，与其他精神症状相比，其对自杀意念的影响却很少受到关注。
数据来自 2014 年韩国国家健康和营养检查调查。自杀意念通过患者健康问卷-9 的第 9 项进行测量。身体活动通过国际身体活动问卷（IPAQ）进行测量，并根据活动水平分为三组。对整个样本、男性和女性进行了多因素逻辑回归分析。使用了以下三种模型：模型 1（调整了社会人口统计学和与健康相关的变量）、模型 2（另外调整了主观身体形象）和模型 3（另外调整了诊断为抑郁症）。
与低 IPAQ 组相比，整个样本的模型 3 中，中 IPAQ 组与自杀意念降低显著相关（OR，0.733；95%CI，0.538-0.999），并且在所有女性模型中也是如此。然而，高 IPAQ 组没有显著关联。在男性中，IPA Q 组均无显著关联。
这是一项横断面研究。因此，不能确定因果关系的方向。本研究还调查了过去两周的自杀意念，这可能与过去一年进行的研究不一致。
身体活动与自杀意念之间的有益关系在男性和高活动水平个体中较弱。建议根据性别和活动水平制定详细的身体活动指南。
