Precarious employment has been identified as a potentially damaging stressor. Conversely, social support networks have a well-known protective effect on health and well-being. The ways in which precariousness and social support may interact have scarcely been studied with respect to either perceived stress or objective stress biomarkers. This research aims to fill this gap by means of a cross-sectional study based on a non-probability quota sample of 250 workers aged 25-60 in Barcelona, Spain. Fieldwork was carried out between May 2019 and January 2020. Employment precariousness, perceived social support and stress levels were measured by means of scales, while individual steroid profiles capturing the chronic stress suffered over a period of a month were obtained from hair samples using a liquid chromatography-tandem mass spectrometry methodology. As for perceived stress, analysis indicates that a reverse buffering effect exists (interaction B = 0.22, = 0.014). Steroid biomarkers are unrelated to social support, while association with precariousness is weak and only reaches significance at < 0.05 in the case of women and 20ß dihydrocortisone metabolites. These results suggest that social support can have negative effects on the relationship between perceived health and an emerging stressful condition like precariousness, while its association with physiological measures of stress remains uncertain.
不稳定性就业已被确定为一种潜在的破坏性压力源。相反，社会支持网络对健康和幸福具有显著的保护作用。关于感知压力或客观压力生物标志物，不稳定和社会支持之间的相互作用方式几乎没有被研究过。本研究旨在通过对西班牙巴塞罗那 250 名 25-60 岁工人进行的非概率配额抽样的横断面研究来填补这一空白。实地工作于 2019 年 5 月至 2020 年 1 月进行。通过量表测量就业不稳定、感知社会支持和压力水平，同时使用液相色谱-串联质谱法从头发样本中获得个体类固醇谱，以捕获一个月内承受的慢性压力。至于感知压力，分析表明存在反向缓冲效应（交互 B = 0.22， = 0.014）。类固醇生物标志物与社会支持无关，而与不稳定性的关联较弱，仅在女性和 20β 二氢皮质酮代谢物的情况下达到 < 0.05 才有统计学意义。这些结果表明，社会支持可能对感知健康与不稳定等新兴压力条件之间的关系产生负面影响，而其与压力的生理测量指标的关联仍不确定。
