A recent European study found a significant correlation between obesity and increased rates of sick leave among workers, shedding light on the economic and productivity implications of excess weight.

According to the study, individuals categorized as overweight face a 12% higher likelihood of requiring sick leave, with markedly elevated rates among those classified as obese, defined by a body mass index (BMI) of 30 or higher.

The research revealed that individuals with a BMI between 30 and 35 are 36% more likely to take sick leave, a figure that rises to 61% for those with a BMI between 35 and 40. Alarmingly, individuals classified as extremely obese, with a BMI exceeding 40, are 147% more likely to be absent due to health-related reasons.

The findings, although not inclusive of the U.K., have prompted concern in the nation where approximately two-thirds of adults are overweight or obese. The economic impact of excess weight in the U.K. is estimated at £98 billion annually, encompassing healthcare costs and lost productivity.

Kat Jenner, director of the Obesity Health Alliance, emphasized the urgent need for addressing food-related health issues to improve wellbeing, enhance economic growth, and ensure the sustainability of the healthcare system.

"Prioritising the nation's food-related ill-health is vital for any government serious about improving wellbeing, increasing growth and ensuring the sustainability of the NHS," Jenner said, The Guardian reported.

The study, encompassing 26 European countries and over 122,000 participants, underscores that overweight and obese individuals are not only more prone to sick leave but also tend to take longer absences, averaging at least seven days annually.

Researchers warned of the significant impact of obesity on workforce productivity and the resultant economic burden.

Globally, the costs associated with overweight and obesity are projected to escalate substantially, reaching $4.32 trillion by 2035. Richard Sloggett, a healthcare consultant, advocates for a comprehensive obesity strategy as a top priority for future governments to mitigate the longstanding inaction on this pressing issue.

"The dash for growth that the next government needs to deliver will not work unless it is underpinned by a clear and system-wide obesity strategy. Implementing obesity policies that are isolated, much delayed and watered down will not cut it," Sloggett explained.

"When setting priorities for the health mission across No 10, Treasury and the Department of Health, reducing obesity rates needs to be right at the top of the list."

In light of these findings, the urgency of implementing effective obesity policies is exposed, with the TUC highlighting the adverse impact on women's economic participation, particularly due to delays in accessing healthcare.

Efforts to enhance support for individuals with health conditions and disabilities, coupled with reforms in the benefits system, are noted as crucial steps toward fostering a healthier and more productive workforce.
