By KAREN ELLISONMAN Associated PressScientists at Harvard Medical School say they have found no link between the stress experienced by workers and their weight and that it does not affect their risk of obesity.
The study, published online Monday in the Journal of Occupational and Environmental Medicine, was based on interviews with 7,000 workers who had been in jobs for at least three years.
Researchers compared the workers’ eating habits to data on the average BMI, or body mass index.
They found no difference in the risk of developing obesity among the workers who were less stressed than those who were more stressed.
The researchers also found no relationship between work and health, although they say that could be because stress could be related to other aspects of the work environment.
They did find a positive association between stress levels and body mass.
The Harvard researchers noted that they did not find a link between stress, health and the risk for obesity.
The Harvard study is part of a larger body of research that suggests stress is linked to an increased risk of heart disease and diabetes.
The authors note that although the results were statistically significant, they are not necessarily definitive.
The researchers caution that their results should not be taken to suggest that workers with higher stress levels are more likely to develop obesity.
