Lost productive time associated with excess weight in the U.S. workforce.

Area of Science:

• Occupational Health
• Public Health
• Health Economics

Background:

• Overweight and obesity are prevalent conditions in the working population.
• Health-related lost productive time (LPT) represents a significant economic burden.
• Understanding the impact of body mass on productivity is crucial for workforce health strategies.

Purpose of the Study:

• To quantify and compare health-related lost productive time (LPT) among normal-weight, overweight, and obese workers.
• To determine the economic cost associated with LPT in different weight categories.
• To explore the role of health status in the relationship between obesity and LPT.

Main Methods:

• A cross-sectional study utilizing national telephone survey data from the U.S. workforce.
• Workers categorized into normal-weight, overweight, and obese groups based on Body Mass Index (BMI).
• Comparison of LPT in hours and monetary value across the defined weight groups.

Main Results:

• Obese workers reported significantly higher LPT (42.3%) compared to normal-weight (36.4%) and overweight (34.7%) workers.
• Health status was identified as a mediator between obesity and LPT.
• Obesity contributed an estimated $11.70 billion in excess LPT costs, totaling $42.29 billion, with presenteeism accounting for 67.8% of this cost.
• Overweight workers did not represent a significant source of excess LPT.

Conclusions:

• Interventions aimed at reducing excess weight within the workforce can enhance productivity.
• Improving the health of obese employees is a key strategy for boosting U.S. workforce productivity.
• Targeted health initiatives for obese workers may yield substantial economic benefits through reduced LPT.
