Effectiveness of workplace interventions for health promotion

Workplaces are an important setting for health promotion, offering established infrastructure, daily access to large populations, and opportunities to engage groups that are often under-represented in such initiatives. Although the effectiveness of workplace health promotion has been evaluated in reviews focusing on specific interventions, a comprehensive overview is needed. To address this gap, we present a quality-informed horizontal analysis encompassing 88 reviews and 339 meta-analysed effect estimates published between 2011 and 2024, covering a broad range of workplace health interventions.

Mental health and stress reduction were the most frequently studied targets (36%), followed by weight management and cardiometabolic health (25%), health-related behaviours (22%), and musculoskeletal disorders and pain (17%).
