This study examined the individual and combined effects of a height-adjustable desk and an online behavioral intervention on sedentary behavior and health among university employees working from home.
Participants (N = 95) were randomly assigned to one of four conditions: Desk Only, Program Only, Desk + Program, or Control. Desk participants received a height-adjustable desk; program participants received a 12-week web-based intervention. Outcomes measured at baseline and post-intervention included workday sitting and cardiometabolic health outcomes.
Reductions in sitting were largest in the Desk + Program condition (-206 min/workday; d = 1.84), followed by the Desk Only condition (-122 min/workday; d = 0.98), and the Program Only condition (-96 min/workday; d = 1.13). There were no significant changes in the health outcomes assessed.
Both a height-adjustable desk and an online behavioral intervention effectively reduced occupational sitting, and a combined approach was most effective.
本研究探讨了可调节高度办公桌和在线行为干预对居家办公的大学员工久坐行为和健康的个体及联合影响。
参与者（N = 95）被随机分配到以下四种情况之一：仅使用办公桌、仅参加项目、办公桌 + 项目或对照组。使用办公桌的参与者获得一张可调节高度的办公桌；参加项目的参与者接受为期12周的网络干预。在基线和干预后测量的结果包括工作日久坐时间和心血管代谢健康指标。
在办公桌 + 项目组中，久坐时间减少最多（-206分钟/工作日；d = 1.84），其次是仅使用办公桌组（-122分钟/工作日；d = 0.98）和仅参加项目组（-96分钟/工作日；d = 1.13）。所评估的健康指标没有显著变化。
可调节高度办公桌和在线行为干预均能有效减少工作时的久坐时间，联合使用的方法最为有效。
