| Abstract |
This study systematically reviewed workplace-based multicomponent weight management interventions for employees with overweight or obesity and identified intervention components, providers, delivery charac- teristics, and outcomes. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, six electronic databases were searched using eligibility criteria based on the Population, Intervention, Comparator, and Outcome framework. Methodological quality was assessed using the Joanna Briggs Institute critical appraisal tools. Thirty-one studies were included. More than half were conducted in the United States, and 14 (45.2%) were randomized controlled trials. All interventions included behavioral/self- management strategies; nutrition, physical activity, and counseling/coaching were also common. Dietitians or nutrition professionals were the most frequently reported providers, followed by physical activity professionals and health or lifestyle coaches, whereas nurses and physicians participated less often. Hybrid delivery combining face-to-face and digital approaches was most frequent, and digital technologies were used in 23 studies (74.2%). All studies assessed anthropometric or obesity-related outcomes, most commonly weight or weight change (96.8%) and body mass index (77.4%). Cardiometabolic/physical health, behavioral, and psychosocial outcomes were also reported, whereas workplace-related outcomes were rarely assessed. Only seven studies conducted postintervention follow-up. Future studies should standardize process measures and evaluate long-term and organizational outcomes. |
