Impact of Ergonomics on Cardiometabolic Risk in Office Workers: Transition to Activity-Based Working With Height-Adjustable Desk.

OBJECTIVE Ergonomic office redesigning possibly improves physical activity (PA) and sedentary behavior (SB); however, its impact on cardiometabolic risk has not yet been determined. This study aimed to examine the effect of office relocation on cardiometabolic risk factors. METHODS Annual health check-up data of 95 office workers from four offices in Tokyo, Japan, who relocated to an office with activity-based working (ABW) and height-adjustable desk (HAD) and a propensity-score matched control-cohort were analyzed. PA and SB on weekdays were measured only in the relocation group before and 10 months after relocation. RESULTS Significant interactions were observed for waist circumference, high-density lipoprotein cholesterol, and glycosylated hemoglobin (HbA1c). HbA1c changes showed a significant negative association with moderate-to-vigorous-intensity PA. CONCLUSION An ABW office with HAD improves cardiometabolic risk factors in office workers, possibly through changes in PA and SB.
