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.
