MONDAY, September 27 (Health.com) — Being obese can hurt your health, but it may also make it harder to do your job. According to a new study, obese workers take more sick days than their peers and are more likely to say they’ve experienced drops in productivity.
Researchers in the Netherlands anonymously surveyed 10,674 workers at 49 companies who performed a variety of jobs including office work, industrial manufacturing, and construction.
Compared to their peers of normal weight, the obese workers in the study were 66% more likely to have missed between 10 and 24 days of work due to illness or other health problems in the previous year, and they were 55% more likely to have missed 25 or more days.
When they were at work, obese workers tended to be less productive than they thought they should be. Obese people were 29% more likely than normal-weight workers to say that they were 30% less productive than usual on their most recent regular day of work.
Other components of an unhealthy lifestyle were also associated with lost productivity. Smokers were 30% more likely than nonsmokers to have taken 10 to 24 sick days in the previous year, and smoking put an even greater dent in productivity than obesity, according to the study, which appears in the journal Occupational and Environmental Medicine.
Because it was based on a one-time survey, the study couldn’t show that obesity, smoking, or other health factors directly affected sick time or productivity. But the link seems plausible, given the range of health problems associated with both obesity and smoking.
Indeed, 83% of the obese workers in the study reported having at least one chronic disease, including heart disease, diabetes, depression, and joint or muscle pain. Sixty-nine percent and 75% of normal and overweight workers, respectively, reported having one chronic disease.
The study shouldn’t be viewed as justifying discrimination against obese people in the workplace, says the lead author, Suzan Robroek, a public health researcher at Erasmus Medical Center, in Rotterdam. (The Netherlands prohibits discrimination based on weight, as do some U.S. states and municipalities.)
Rather, Robroek says, the findings suggest that employers should be doing more to encourage their employees to lose weight and stay healthy. “Employers could facilitate healthy lifestyles and pay attention to healthy working conditions,” she says. “For example, they can encourage active commuting [and] healthy options in the [cafeteria].”
