LONG TERM EFFECTS OF HYPERTENSION PROGRAMS IN INDUSTRY

这项研究将衡量三种高血压控制的长期影响， 1978年在三家汽车制造厂实施的干预措施， 并于1981年终止。 三种干预措施的有效性 维持高水平的血压控制在三个实验 在此期间建立了一个研究中心（与第四个对照中心相比）， 项目初期。 然而，时间太短，无法确定 从改善的高血压控制中最终预期的益处，即， 减少心血管事件，从而降低健康福利成本 和更少的病假缺勤。 拟议的研究将评估（a）继续保持良好的控制 在实验地点的高血压人群中，和（B） 2004 - 2005年期间缺勤率和健康福利利用率的变化 高血压患者，与相应的血压正常者相比， 的网站，并与高血压患者在控制网站。 所有 高血压患者和匹配的血压正常者将在 研究第一年，以及关于出勤率和健康福利的数据 将收集自终止以来的时间段内的利用率， 1984年底开始研究。 数据将与数据集合并 从最初的研究和多变量分析技术将是 用于识别与保持良好控制相关的因素， 以及与患病率低、缺勤率低和健康状况差有关的因素 福利利用（特别是与心血管疾病有关的）。 不同的磨损率从工厂，和他们可能的 与高血压的关系，也将进行探讨。

The study will measure the long-term impact of three hypertension control interventions implemented in three automobile manufacturing plants in 1978, and terminated in 1981. The effectiveness of the three interventions at maintaining high levels of blood pressure control in the three experimental sites (as compared with a fourth control site) was established during this initial project period. However, the period was too short to identify the benefits eventually expected from improved hypertension control, i.e., fewer cardiovascular events, and consequently lower health benefit costs and less sickness absenteeism. The proposed study will assess (a) continued maintenance of good control within the hypertensive populations at the experimental sites, and (b) changes in absenteeism and health benefit utilization rates among the hypertensives, as compared with matched normotensives at the respective sites, and as compared with hypertensives at the control site. All hypertensives and matched normotensives will be re-screened during the first year of the study, and data on attendance and health benefit utilization will be collected for the time period since termination of the initial study through the end of 1984. Data will be merged with datasets from the initial study and multivariate analysis techniques will be utilized to identify factors associated with maintenance of good control, as well as factors associated with low sickness absenteeism and low health benefit utilization (especially as related to cardiovascular disease). Differential rates of attrition from the plant, and their possible association with hypertension, will also be explored.
