Outline of Final Research Achievements

Blood pressure (BP) measured at worksite (worksite BP) was significantly higher than morning home BP, which is well known as a strong risk factor for cardiovascular events. The average value and the peak value of worksite BPs were significantly associated with left ventricular mass index, an index for organ damage. In addition, the analysis of study data using newly developed wrist watch-type wearable BP monitoring device revealed that daytime BPs during daily activities were elevated by the effects of negative emotion and stress.

Academic Significance and Societal Importance of the Research Achievements

本研究により、職場またはストレス環境下において血圧が上昇することが明確に示された。これらの血圧上昇は心血管イベント発症リスクの増大に関連しており、職場高血圧やストレス高血圧を適切に管理することの重要性が示唆された。隠れた心血管リスクを簡便に検出できる職場血圧測定は、QOLの低下が本人、家族、さらには社会に対するインパクトが大きい働き盛り世代における心血管イベント発症の回避につながると考える。
