Full-time workers who are overweight or obese and have other chronic health conditions miss an estimated 450 million additional days of work each year compared with healthy workers—resulting in more than $153 billion in lost productivity each year.
That’s the word from Gallup-Healthways Well-Being Index data collected between Jan. 2 and Oct. 2, 2011. Gallup surveyed 109,875 full-time employees (those who work at least 30 hours per week) during this period.
The Gallup-Healthways Well-Being Index uses respondents’ self-reports of their height and weight to calculate body mass index (BMI) scores. BMI values of 30 or higher are classified as “obese,” 25 to 29.9 are “overweight,” and 18.5 to 24.9 are “normal weight.”
Chronic health conditions in this analysis include:

Gallup calculated unhealthy days using respondents' answers to the question, “During the past 30 days, for about how many days did poor health keep you from doing your usual activities?”
Full-time workers who are of normal weight and don’t suffer from chronic health conditions make up 13.9% of the U.S. workforce and average 0.34 unhealthy days each month—about four days per year.
The average number of unhealthy days per month is slightly higher (0.36) among those who are overweight or obese and don’t have additional chronic health conditions.
Unhealthy days per month increase to 1.08 for workers who are overweight or obese and have one to two additional chronic health conditions.
Workers who are of an above-normal weight and have three or more chronic health conditions report a significantly higher average number unhealthy days per month—3.51, or about 42 days per year.
To estimate how unhealthy days per month translate into missed work days, Gallup asked workers, “Earlier, you indicated that you had XX days in the last month where poor health prevented you from doing your usual activities. How many actual work days in the last month did you not work due to poor health?”
The results indicated that one unhealthy day per month for full-time workers is equivalent to about 0.31 actual missed days of work.
In comparison, the $153 billion in annual lost productivity costs linked to unhealthy workers in the U.S. is more than four times the cost in the United Kingdom. About 14% of full-time U.S. workers are of a normal weight and have no chronic illness, compared with 20% in the U.K.
“The high percentages of full-time workers who have less than ideal health are a significant drain on productivity for U.S. businesses,” Gallup reports. “However, employees and employers have the opportunity to potentially increase productivity if they address the health issues that are currently plaguing the workplace.”
