目的：先前的研究表明，低静息心率可能是儿童反社会和攻击行为的最佳复制生物学相关因素。然而，对这种关系的纵向测试很少，对潜在的混杂因素和中介因素的控制很少，也没有对其跨文化普遍性进行测试。这项研究检验了这样的假设：3 岁时的低静息心率预示着 2 岁时的攻击行为。方法：对来自毛里求斯的 1,795 名男性和女性儿童 3 岁时的静息心率进行了评估。使用儿童行为检查表在 11 岁时评估攻击性和非攻击性反社会行为。结果：攻击性儿童的心率低于非攻击性儿童 (p < .001)。相反，心率低的人比心率高的人更具攻击性 (p < .003)。与性别或种族没有相互作用。证据表明低心率对攻击性反社会行为具有特异性。心率的组间差异不能归因于 11 种生物、心理和精神因素和混杂因素。结论：得出的结论是，低静息心率是一种反映无所畏惧和寻求刺激的部分遗传特征，是后来攻击行为的重要的、诊断特异性的、复制良好的早期生物标志。
Objective: Previous studies indicate that low resting heart rate is probably the best-replicated biological correlate of childhood antisocial and aggressive behavior. Nevertheless, there have been few longitudinal tests of this relationship, little control over potential confounds and mediators, and no test of its cross-cultural generalizability. This study tests the hypothesis that low resting heart rate at age 3 years predicts aggression at age ii years. Method: Resting heart rate at age 3 years was assessed in 1,795 male and female children from Mauritius. Aggressive and nonaggressive forms of antisocial behavior were assessed at age 11 years using the Child Behavior Checklist. Results: Aggressive children had lower heart rates than nonaggressive children (p < .001). Conversely, those with low heart rates were more aggressive than those with high heart rates (p < .003). There were no interactions with gender or ethnicity. Evidence was found for specificity of low heart rate to aggressive forms of antisocial behavior. Group differences in heart rate were not attributable to 11 biological, psychological, and psychiatric mediators and confounds. Conclusions: It is concluded that low resting heart rate, a partly heritable trait reflecting fearlessness and stimulation-seeking, is an important, diagnostically specific, well-replicated, early biological marker for later aggressive behavior.
