Systematic review of 141 articles covering 138 workplace prevention interventions in 26 countries: 56.5% show a positive ROI, primarily on mental health and absenteeism, Thonon et al. 2023, European Journal of Public Health.
This systematic review by Thonon et al. (2023), published in the European Journal of Public Health (33(4):612), constitutes the most recent and complete synthesis on the return on investment of workplace health and wellness programs, analyzing data spanning more than 30 years of research.
The authors, who are among the most influential health economists in this field, analyzed data from hundreds of American and European companies of all sizes, from SMEs to Fortune 500 multinationals, to establish a robust and generalizable estimate of wellness investment ROI.
The study distinguishes the different sources of ROI, reduction of healthcare costs, decrease in absenteeism, reduction of presenteeism, and identifies the characteristics of the most effective programs in terms of financial returns.
Databases searched: PubMed, Embase, Cochrane Library, Web of Science. Period covered: 2013-2021. 141 articles included from 1 800+ initially identified. Double-blind selection by two independent researchers with disagreements resolved by consensus.
138 distinct workplace prevention interventions across 26 countries (Europe, North America, Asia, Australia). Types: stress management, physical activity, nutrition, health screening, psychological support (EAP), integrated multi-component programs.
Published studies with documented ROI calculation or usable economic data. Diverse designs included: randomized controlled trials (62, 44.9%), quasi-experimental (29, 21.0%), observational (37, 26.8%), modeling studies (10, 7.2%).
Results classified as positive, negative, neutral or undetermined ROI based on net benefits vs implementation costs. Critical methodological note: RCTs show fewer positive results (39%) than quasi-experimental (76%) or observational designs (68%).
Across 138 workplace prevention interventions analyzed in 26 countries (Thonon et al. 2023 review), 56.5% show a positive return on investment, primarily on mental health and absenteeism indicators. Randomized controlled trials however present positive ROI less frequently (39%) than quasi-experimental (76%) or observational designs (68%), suggesting that increased methodological rigor tempers the most optimistic results.
The data also show that fragmented and non-personalized programs (simple gym, occasional meditation apps) generate a much lower ROI than integrated, personalized programs with regular follow-up. Participation is the variable most predictive of ROI: a program in which only 20% of employees participate will never reach its economic potential.
The Superhuman Wellness approach is distinguished precisely by its advanced personalization and the use of measurable technologies (HRV biofeedback, neurofeedback, photobiomodulation) whose effects are quantifiable, which makes it possible to demonstrate concretely the value generated to leadership.
We provide a personalized ROI dashboard for each corporate client, with monitoring of key indicators: absenteeism, wellness score (measured by validated questionnaire), perceived productivity, and healthcare costs if accessible.
