Hair cortisol concentrations (HCC) are assumed to reflect integrated cortisol secretion over extended periods of time and may provide a sensitive marker for stress-associated endocrine changes. Here, we report data from two independent studies of 155 (study I) and 58 participants (study II) in which HCC associations with different stress-related measures and body mass index (BMI) were investigated. Consistent evidence for positive associations between HCC and BMI was seen across both studies (study I: r=.33, p<.001; study II: r=.42, p=.001). On the other hand, findings failed to reveal reliable HCC associations with psychosocial variables, showing only a positive relationship with self-reported social overload in study II (r=.29, p=.03) but not with other stress-related measures.
头发皮质醇浓度 (HCC) 被认为反映了长时间内皮质醇分泌的综合情况，并且可能是应激相关内分泌变化的敏感标志物。在这里，我们报告了来自两个独立研究的数据，共有 155 名参与者（研究 I）和 58 名参与者（研究 II），其中研究了 HCC 与不同应激相关指标和体重指数 (BMI) 的关联。两项研究均一致表明 HCC 与 BMI 之间存在正相关（研究 I：r=.33，p<.001；研究 II：r=.42，p=.001）。另一方面，研究结果未能揭示 HCC 与心理社会变量之间可靠的关联，仅在研究 II 中显示出与自我报告的社会超负荷呈正相关（r=.29，p=.03），但与其他应激相关指标无关。
