{Reference Type}: Journal Article {Title}: Transitioning to Working from Home Due to the COVID-19 Pandemic Significantly Increased Sedentary Behavior and Decreased Physical Activity: A Meta-Analysis. {Author}: Chaudhary N;Jones M;Rice SPM;Zeigen L;Thosar SS; {Journal}: Int J Environ Res Public Health {Volume}: 21 {Issue}: 7 {Year}: 2024 Jun 28 {Factor}: 4.614 {DOI}: 10.3390/ijerph21070851 {Abstract}: At the start of the COVID-19 pandemic, many workplaces transitioned to remote work, which altered lifestyle behaviors. We conducted a meta-analysis to understand if the transition to working from home due to the pandemic affected workers' physical activity and sedentary behavior worldwide. We reviewed articles published between November 2019 and May 2022. Of an initial 3485 articles, a total of 17 were included, 15 of 17 were included for their physical activity (PA) comparisons (n = 36,650), and 12 of 17 (n = 57,254) were included for their sedentary behavior (SB) comparisons (10 studies have data for both PA and SB). This work is registered through PROSPERO (CRD42022356000). Working from home resulted in a significant decrease in PA (Hedge's g = -0.29, 95% CI [-0.41, -0.18]) and an increase in SB (Hedge's g = +0.36, 95% CI [0.20, 0.52]). Working from home impaired preventative activity behaviors, and these results are relevant to worker health as the future of work evolves beyond the pandemic.
