【摘要】 目的探讨职业紧张相关因素对体质指数(BMI)的影响。方法采用横断面研究方法对115名机车调度员进行调查,以职业紧张调查量表测试职业紧张因素、人格特征、心理性紧张反应,测量身高、体质量,计算BMI。结果工作困难、外控性和紧张易感性高水平组超重与肥胖率高于低水平组,决定自由度和工作中的人际关系高水平组超重与肥胖率低于低水平组,差异均有统计学意义(P<0.05)。多因素logistic回归分析显示,紧张易感性是引起BMI增加的危险因素(OR=1.328),而工作中的人际关系是降低BMI的保护因素(OR=0.362)。结论职业紧张因素和不利于应对应激的人格特征可能会引起BMI的改变。更多还原

【Abstract】 Objective To explore the impact of occupational stress on body mass index(BMI).Methods A cross-sectional epidemiological study was conducted in 115 dispatchers.The occupational stressors,personalities,occupational strain and coping with stress were measured using Occupational Stress Instrument.Height and weight were measured and BMI was calculated by[weight/height2].Results Chi-square test analysis indicated that the rates of overweight and obesity were higher in high score groups of job difficulty,external control and susceptibility to stress than those of the low score groups,but the rates of overweight and obesity were lower in high score groups of decision attitude and work relationships than those of the lower groups.Multiple logistic regression analysis indicated that susceptibility to stress was the risk factor of BMI(OR=1.328),while work relationships might be the protective factor of BMI(OR=0.362).Conclusions Relevant factors of occupational stress and inappropriate personality to cope with the stress may lead to the change of the body mass index.更多还原
