Relationships between work-related psychological and physical stress responses and counts of white blood cells (WBCs), neutrophils, and lymphocytes were investigated in 101 daytime workers. Counts of WBCs and neutrophils were positively associated with smoking and inversely correlated with high density lipoprotein (HDL)-cholesterol levels. Additionally, general fatigue score as measured by the profile of mood state was positively correlated with WBC and neutrophil counts whereas lymphocyte counts was not significantly associated with fatigue score. Multiple regression analysis showed that WBC count was significantly related to general fatigue, age, and HDL-cholesterol levels. Neutrophil count was significantly related to HDL-cholesterol levels and fatigue score. Among various psychological stress response variables, general fatigue may be a key determinant of low-grade inflammation as represented by increases of WBC and neutrophil counts.
在101名白天工作的人群中,研究了与工作相关的心理和生理应激反应与白细胞(WBC)、中性粒细胞和淋巴细胞计数之间的关系。白细胞和中性粒细胞计数与吸烟呈正相关,与高密度脂蛋白(HDL)胆固醇水平呈负相关。此外,用情绪状态剖面图测量的总体疲劳评分与白细胞和中性粒细胞计数呈正相关,而淋巴细胞计数与疲劳评分无显著关联。多元回归分析表明,白细胞计数与总体疲劳、年龄和HDL胆固醇水平显著相关。中性粒细胞计数与HDL胆固醇水平和疲劳评分显著相关。在各种心理应激反应变量中,总体疲劳可能是以白细胞和中性粒细胞计数增加为代表的低度炎症的关键决定因素。
