Most health-related productivity loss in the American workforce isn’t showing up in absence records. It’s accumulating while employees are still at their desks. New research from Vitality, a global health and wellness company, finds that US workers lose an average of 63.4 productive days per year due to poor physical and mental health, and 53.9 of those days, or 85% of the total, are lost through presenteeism: employees present at work but operating below capacity.
The findings come from Vitality’s Global Health and Productivity Index 2026, conducted by FGS Global and RAND Europe across five markets. The US sample comprised 2,079 workers surveyed between February 21 and March 16. Because Vitality sells health and wellness programs to employers and health plans, its commercial interest in the findings should be noted, though the RAND Europe partnership provides independent analytical oversight.
The US total of 63.4 lost days sits well above the five-market average of 54.8. Only Germany, at 69.3 days, ranks higher. By contrast, US workers lose just 9.5 days annually through absence, meaning traditional absence tracking captures roughly one in seven days of actual health-related productivity loss.
The research points to a structural mismatch in how employers deploy their health benefit spending. While US employers offer a broader range of medical support than employers in any other market studied, that support skews toward treating illness rather than preventing it. Only 18% of US workers report access to employer-organized health screenings, which can detect conditions when they are far easier and less costly to address.
The workforce health picture underlying that gap is substantial. Almost one in three US workers, 29%, is classified as obese, against a five-market average of 18%. Sixty-five percent report moderate or serious psychological distress. Thirty-two percent say their health has a medium or high impact on their productivity while they are working.
These figures land at a moment when employers are already under pressure on healthcare costs. MetLife’s 2026 US Employee Benefit Trends Study, which surveyed 2,480 HR decision-makers, found that “controlling healthcare costs” has surpassed productivity, retention, and talent attraction as employers’ leading benefits objective - the first time that’s happened since 2022.
The Vitality data adds a dimension that cost-control conversations often miss: cutting claims costs is not the same as improving the workforce health that drives those claims.
The index identifies a concrete lever. Workers who feel their manager genuinely cares about their wellbeing lose nine fewer productive days per year than those who don’t. Workers at high risk across all five identified health risk domains - mental wellbeing, physical health, work strain, lifestyle risk, and concern about AI’s impact on their jobs - lose an estimated 119 productive days annually, close to half a working year.
John Feeney, vice president of group sales and market development at Renaissance Benefits in Washington, D.C., has noted that benefits advisors who spend 90 to 95% of their bandwidth on medical plan design are missing the supplemental and preventive layer that addresses financial exposure when health deteriorates. That is also where presenteeism costs accumulate most.
“The conversation shifts from ‘can we cover everything’ to ‘how do we provide the right mix of coverage and financial protection,’” Feeney said.
RAND Europe, which partnered on the study, made the same point. Christian van Stolk, deputy chief executive at RAND Europe, said:. “While absence often attracts the most attention from employers, it is presenteeism, when left unaddressed, that has the far greater impact on productivity,” said Christian van Stolk, deputy chief executive at RAND Europe.
