Workplace health promotion is important in the prevention of non-communicable diseases among employees. Previous workplace health programs have shown benefits such as lowered disease prevalence, reduced medical costs and improved productivity. This study aims to evaluate the impact of a 6-year workplace health promotion program on employees' blood pressure in a public university.
In this prospective cohort study, we included 1,365 employees enrolled in the university's workplace health promotion program, a program conducted since 2008 and using data from the 2008-2013 follow-up period. Participants were permanent employees aged 35 years and above, with at least one follow up measurements and no change in antihypertensive medication during the study period. Baseline socio-demographic information was collected using a questionnaire while anthropometry measurements and resting blood pressure were collected during annual health screening. Changes in blood pressure over time were analyzed using a linear mixed model.
The systolic blood pressure in the hypertension subgroup decreased 2.36 mmHg per year (p<0.0001). There was also significant improvement in systolic blood pressure among the participants who were at risk of hypertension (-0.75 mmHg, p<0.001). The diastolic blood pressure among the hypertensive and at risk subgroups improved 1.76 mmHg/year (p<0.001) and 0.56 mmHg/year (p<0.001), respectively. However, there was no change in both systolic and diastolic blood pressure among participants in the healthy subgroup over the 6-year period.
This study shows that continuing participation in workplace health promotion program has the potential to improve blood pressure levels among employees.
职场健康促进对于预防员工的非传染性疾病至关重要。以往的职场健康项目已显示出诸多益处，如降低疾病患病率、减少医疗成本以及提高生产力。本研究旨在评估一项为期6年的职场健康促进项目对一所公立大学员工血压的影响。
在这项前瞻性队列研究中，我们纳入了1365名参加该大学职场健康促进项目的员工，该项目自2008年开展，采用的是2008 - 2013年随访期的数据。参与者为35岁及以上的长期员工，至少有一次随访测量，且在研究期间抗高血压药物治疗无变化。使用问卷收集基线社会人口学信息，同时在年度健康筛查期间收集人体测量数据和静息血压。采用线性混合模型分析血压随时间的变化。
高血压亚组的收缩压每年下降2.36 mmHg（p<0.0001）。高血压风险参与者的收缩压也有显著改善（-0.75 mmHg, p<0.001）。高血压亚组和高血压风险亚组的舒张压分别每年改善1.76 mmHg（p<0.001）和0.56 mmHg（p<0.001）。然而，健康亚组的参与者在6年期间收缩压和舒张压均无变化。
本研究表明，持续参与职场健康促进项目有可能改善员工的血压水平。
