工作需求和控制模型是评估工作压力导致的紧张工作条件的一个实用模型，它解释了高工作要求如何造成生理和心理不良后果，包括心血管风险因素（工作量，除了完成工作时间限制之外）以及工人在工作场所对其工作的控制力低（缺乏决策）。本研究旨在探讨心血管疾病危险因素（包括体重指数、心率、血压、胆固醇和吸烟）与工作需求和工作控制之间的关系。这项前瞻性队列研究于2009年在伊朗南部的石油化工行业的500名工人中进行。采用简单随机统计方法选择研究人群。他们完成了工作需求和控制问卷。心血管病危险因素数据从工人卫生档案中提取。采用卡方检验（χ2）和假设检验（η）评估不同量化变量与个体人口学特征和心血管危险因素之间的可能关系。本研究结果显示，工作需求控制模式与心血管疾病危险因子有显著相关。卡方检验结果显示心率与肥胖的相关性最高（χ2 = 145.078），吸烟与BMI的相关性分别为χ2 = 85.652和χ2 = 30.941。随后，胆固醇和高血压的假设检验结果分别为0.469和0.684。工作压力可能与伊朗一家石化公司男性员工心血管风险因素风险增加有关。工作需求和控制模型中的参数可以作为工作压力发生概率的可接受的预测因子，随后显示出高的CVD风险因素趋势。
One of the practical models for the assessment of stressful working conditions due to job strain is job demand and control model, which explains how physical and psychological adverse consequences, including cardiovascular risk factors can be established due to high work demands (the amount of workload, in addition to time limitations to complete that work) and low control of the worker on his/her work (lack of decision making) in the workplace. The aim of this study was to investigate how certain cardiovascular risk factors (including body mass index [BMI], heart rate, blood pressure, cholesterol and smoking) and the job demand and job control are related to each other. This prospective cohort study was conducted on 500 workers of the petrochemical industry in south of Iran, 2009. The study population was selected using simple random statistical method. They completed job demand and control questionnaire. The cardiovascular risk factors data was extracted from the workers hygiene profiles. Chi-square (χ2) test and hypothesis test (η) were used to assess the possible relationship between different quantified variables, individual demographic and cardiovascular risk factors. The results of this study revealed that a significant relationship can be found between job demand control model and cardiovascular risk factors. Chi-square test result for the heart rate showed the highest (χ2 = 145.078) relationship, the corresponding results for smoking and BMI were χ2 = 85.652 and χ2 = 30.941, respectively. Subsequently, hypothesis testing results for cholesterol and hypertension was 0.469 and 0.684, respectively. Job strain is likely to be associated with an increased risk of cardiovascular risk factors among male staff in a petrochemical company in Iran. The parameters illustrated in the Job demands and control model can act as acceptable predictors for the probability of job stress occurrence followed by showing a high trend of CVD risk factors.
