Background The experience of intimate partner violence (IPV) is stressful. One objective way to monitor it is to assess victims' stress response by measuring the concentration of their salivary cortisol, the major stress hormone released by the hypothalamic-pituitary-adrenal axis. Objective We investigated how the IPV experienced by women in Cameroon affects their stress levels and those of their children. Method We recruited 50 mother-child dyads exposed to IPV and a control group of 25 mother-child dyads. All mothers completed questionnaires, including the Revised Conflict Tactics Scale to assess IPV, the Sense of Coherence Scale, and the Self-Esteem Scale, to assess their psychological resources. Mothers were asked to collect 3 saliva samples from themselves and 3 from their children on a single weekday: immediately after waking up, 30 minutes after waking up, and 45 minutes after waking up. The total cortisol secretion over the first hour after awakening was determined by calculating the area under the curve with respect to the ground (AUCg). Results Mothers exposed to IPV exhibited higher total post-awakening cortisol concentrations compared with those in the control group. However, no significant difference was found between exposed and non-exposed children. In addition, higher IPV, specifically injuries, was significantly and positively associated with greater AUCg among mothers exhibiting lower self-esteem. When self-esteem was high, however, no significant effect of IPV on AUCg was observed. Conclusions Of particular clinical significance is that self-esteem can modulate the stress levels of women exposed to IPV, a valuable insight into the development of effective psychosocial interventions to support IPV victims in sub-Saharan Africa.

HPA 轴活动和自尊在喀麦隆亲密伴侣暴力背景下的调节作用。

背景 亲密伴侣暴力 (IPV) 的经历让人倍感压力。一种客观的监测方法是通过测量唾液皮质醇的浓度来评估受害者的压力反应,唾液皮质醇是下丘脑-垂体-肾上腺轴释放的主要应激激素。目标 我们调查了喀麦隆妇女经历的 IPV 如何影响她们及其子女的压力水平。方法 我们招募了 50 名暴露于 IPV 的母子二人组和一个由 25 名母子二人组组成的对照组。所有母亲都完成了问卷调查,包括用于评估 IPV 的修订冲突策略量表、一致感量表和自尊量表,以评估她们的心理资源。母亲们被要求在一个工作日从自己身上采集 3 个唾液样本,从孩子身上采集 3 个样本:醒来后立即,醒来后30分钟,醒来后45分钟。通过计算相对于地面的曲线下面积 (AUCg) 来确定觉醒后第一个小时内皮质醇的总分泌量。结果 与对照组相比,暴露于 IPV 的母亲表现出更高的觉醒后皮质醇总浓度。然而,在暴露和未暴露的儿童之间没有发现显着差异。此外,较高的 IPV,特别是受伤,与表现出较低自尊的母亲的较高 AUCg 显着正相关。然而,当自尊心高时,IPV 对 AUCg 没有显着影响。结论 具有特殊临床意义的是,自尊可以调节暴露于 IPV 的女性的压力水平,
