摘要

导言静息心率与内化(高脉搏)和外化(低脉搏)障碍有明显的关系。我们旨在探讨静息心率与自杀行为(非致命性自杀未遂[SA]和自杀死亡[SD])之间的关联,并评估这种关联是否超越了内化/外化症状的影响:我们使用 Cox 比例危险模型评估了 357,290 名瑞典男性的静息心率(19 岁)与日后 SA/SD 之间的关联。模型与内化障碍、外化障碍和复原力(应对逆境的能力)进行了对照。共相关分析(比较不同的遗传亲缘关系对)用于控制未测量的家庭混杂因素,并改进因果推断:在基线模型中,低静息心率与SA相关(HR = 0.96; 95% CI: 0.95,0.98),高静息心率与SD相关(HR = 1.04; 95% CI: 1.002,1.07)。在对所有混杂因素进行调整后,与 SA 的关系仍然存在(HR = 0.98)。然而,在控制了协变量后,SD与SA的相关性并没有持续存在。共相关分析不支持因果关系:我们的研究结果为了解自杀行为提出了有趣的病因学问题,但并不支持静息心率在自杀预测中的作用。

A Swedish population-based study to evaluate the usefulness of resting heart rate in the prediction of suicidal behavior among males.

Introduction: Resting heart rate has been distinctly related to both internalizing (high pulse) and externalizing (low pulse) disorders. We aimed to explore the associations between resting heart rate and suicidal behavior (nonfatal suicide attempt [SA] and suicide death [SD]) and evaluate if such associations exist beyond the effects of internalizing/externalizing symptomatology.

Method: We used Cox proportional hazards models to evaluate the associations between resting heart rate (age 19) and later SA/SD in 357,290 Swedish men. Models were controlled for internalizing disorders, externalizing disorders, and resilience (the ability to deal with adversity). Co-relative analysis (comparing pairs of different genetic relatedness) was used to control for unmeasured family confounders and improve causal inference.

Results: In baseline models, low resting heart rate was associated with SA (HR = 0.96; 95% CI: 0.95,0.98) and high resting heart rate with SD (HR = 1.04; 95% CI: 1.002,1.07). The association with SA remained after adjustment for all confounders (HR = 0.98). However, the association with SD did not persist after controlling for covariates. Co-relative analysis did not support causal associations.

Conclusions: Our findings raise interesting etiological questions for the understanding of suicidal behaviors but do not support the usefulness of resting heart rate in suicide prediction.

期刊介绍: An excellent resource for researchers as well as students, Social Cognition features reports on empirical research, self-perception, self-concept, social neuroscience, person-memory integration, social schemata, the development of social cognition, and the role of affect in memory and perception. Three broad concerns define the scope of the journal: - The processes underlying the perception, memory, and judgment of social stimuli - The effects of social, cultural, and affective factors on the processing of information - The behavioral and interpersonal consequences of cognitive processes.
