Outline of Final Research Achievements

In a Japanese working population, we examined the risk of chronic kidney disease (CKD) in relation to leisure-time, occupational, and commuting physical activities. Workers who were standing or walking at work and those who were fairly active at work had a lower risk of developing CKD than sedentary workers. Leisure-time and commuting physical activities were not associated with CKD risk. Our findings suggest that occupational physical activity, not leisure-time and commuting physical activities, are associated with a lower CKD risk in the working population.

Academic Significance and Societal Importance of the Research Achievements

慢性腎臓病は日本人成人の8人に1人が罹患しており、新たな国民病として危惧されているが、仕事中の身体活動量が慢性腎臓病の予防に寄与する可能性が示唆された。スタンディングデスクの導入などによる仕事中の座位時間の短縮が腎機能低下の予防につながることが期待される
