TUESDAY, Sept. 28 (HealthDay News) -- People who engage in
unhealthy habits such as smoking, eating a poor diet and not
getting enough exercise turn out to be less productive on the job,
new Dutch research shows.
Unhealthy lifestyle choices also appear to translate into a
greater need for sick leave and longer periods of time off from
work when sick leave is taken, the study reveals.
The finding is reported in the Sept. 28 online edition of the
Occupational & Environmental Medicine.
"More than 10 percent of sick leave and the higher levels of productivity loss at work may be attributed to lifestyle behaviors and obesity," Alex Burdorf, of the department of public health at Erasmus Medical Center in Rotterdam, the Netherlands, and colleagues noted in a news release from the journal's publisher.
Between 2005 and 2009, Burdorf and his associates surveyed more
than 10,600 people who worked for 49 different companies in the
Participants were asked to discuss both lifestyle and work
habits, rating their work productivity on a scale of 0 to 10, while
offering information about their weight, height, health history and
the number of days they had to call in sick during the prior
The investigators found that 56 percent of those polled had
taken off at least one day in the preceding year because of poor
health. Being obese, smoking, and having poor diet and exercise
habits were contributing factors in just over 10 percent of sick
In particular, obese workers were 66 percent more likely to call
in sick for 10 to 24 days than normal weight employees, and 55
percent more likely to take time off for 25 days or more, the study
Smokers also took more sick leave. The cigarette habit
translated into a 30 percent greater likelihood that a worker would
take off 10 to 24 days because of poor health, Burdorf and his
By contrast, those who drank 10 or more glasses of alcohol each
week were actually less likely to take time off for poor health,
the authors observed.
Overall, the team found that weight appeared to be a key factor
in whether or not an individual had an underlying health issue that
might prompt needing sick leave.
Among obese workers, 83 percent said they had developed at least
one disease, compared with 75 percent of overweight workers and 69
percent of normal weight men and women.
With respect to productivity, 44 percent felt they performed
less than optimally in the day before taking the survey.
Nearly four percent of those with impaired productivity were
found to eat less than the recommended amount of fruits and
vegetables, while smokers made up 20 percent of that group.
"Primary interventions on lifestyle may have a noticeable contribution to maintaining a productive workforce," Burdorf and colleagues concluded in their report.
