This study examined the associations of social support from coworkers and supervisors to workday ambulatory blood pressure and heart rate. Specifically, analyses examined the association of work-related social support to the following measures: 1) baseline blood pressure and heart rate at the start of the workday, 2) blood pressure and heart rate during high stress periods, 3) blood pressure and heart rate levels throughout the workday.
Participants included male (N = 36) and female (N = 34) New York City Traffic Enforcement Agents. Mixed-model regression analyses were used to assess the effects of self-reported measures of workplace social support on workday ambulatory blood pressure.
Workplace support was associated with workday ambulatory blood pressure levels, with the effects depending on the source of support and the gender of the participant. For women, immediate supervisor support was negatively associated with workday systolic blood pressure level, and a similar negative trend was found for workday diastolic blood pressure level. For men, coworker support was negatively associated with workday systolic blood pressure level. We found an interaction of social support with stress level (ie, baseline vs. high stress) such that immediate supervisor support was negatively associated with systolic blood pressure during high-stress conditions, but no effects were found under resting conditions.
These findings suggest that workplace social support is associated with workday ambulatory blood pressure, especially during stressful work periods.
本研究考察了来自同事和上级的社会支持与工作日动态血压及心率之间的关联。具体而言，分析考察了与工作相关的社会支持与以下指标的关联：1）工作日开始时的基线血压和心率；2）高压力时期的血压和心率；3）整个工作日的血压和心率水平。
参与者包括纽约市交通执法人员，男性36名，女性34名。采用混合模型回归分析来评估自我报告的工作场所社会支持指标对工作日动态血压的影响。
工作场所支持与工作日动态血压水平相关，其影响取决于支持来源和参与者性别。对于女性，直属上级的支持与工作日收缩压水平呈负相关，工作日舒张压水平也呈现类似的负向趋势。对于男性，同事的支持与工作日收缩压水平呈负相关。我们发现社会支持与压力水平（即基线与高压力）存在交互作用，即在高压力条件下，直属上级的支持与收缩压呈负相关，但在静息条件下未发现影响。
这些发现表明，工作场所社会支持与工作日动态血压相关，尤其是在压力较大的工作期间。
