摘要:
目的 研究护士职业紧张对其血清中多巴胺(DA)及去甲肾上腺素(NE)水平的影响。 方法 运用职业紧张指数量表对230名护士进行问卷调查,测定其血清中DA及NE浓度。 结果 不同年龄、工龄、文化程度的护士之间,其血清中NE浓度差异有统计学意义(P < 0.05);不同工龄、文化程度的护士之间,其血清中DA浓度差异有统计学意义(P < 0.01)。逐步回归分析结果显示,决策控制、工作单调性、每日紧张感进入了回归方程,是血清中NE浓度的预测因子(R2=0.130,P < 0.01);工作前景、每日紧张感可预测血清中DA的浓度,其中与工作前景呈负相关(P < 0.01),与每日紧张感呈正相关(P < 0.01)。 结论 护士职业紧张对血清中NE、DA水平有影响,职业紧张程度越高,血清中NE、DA含量越高。 Abstract:Objective To explore the effects of occupational stress on serum levels of dopamine (DA) and norepinephrine (NE) among nurses. Methods Occupational Stress Indicator Model was used among 230 nurses.The levels of DA and NE in serum samples were measured. Results The NE levels varied among the selected nurses of different ages,seniorities,and education levels (P < 0.05).The DA levels varied among those of different seniorities and education levels (P < 0.01).The results of stepwise regression analysis showed that decision control,job monotonousness,daily tension were the predictors of serum NE level (R2=0.130,P < 0.01);job prospect and daily tension were the predictors of serum DA level,to which job prospect was negatively correlated (P < 0.01) and daily tension was positively correlated (P < 0.01). Conclusion Occupational stress may affect the levels of dopamine and norepine phrinein the serum of nurses.Higher occupational stress may contribute to the elevated levels of dopamine and norepinephrinegroup
