The finding suggests office work may be an important factor in the obesity epidemic.

"The current findings present the sedentary workplace as a potentially hostile environment in terms of overweight and obesity," conclude the Australian authors of the study, which appears in the August issue of the American Journal of Preventive Medicine. Researchers at Queensland University examined data on nearly 1,600 male and female full-time workers. They found that workers sat an average of more than three hours a day, with 25 percent sedentary on the job for more than six hours a day.

Higher total daily sitting time was associated with a 68 percent increased risk of being overweight or obese.

Overall, men sat an average of 209 minutes while at work, 20 minutes more than the average for women. Those extra 20 minutes may make a difference: The study found a significant association between sitting time and overweight and obesity in men, but not in women.

Getting workers up and exercising may favourably affect their bosses' bottom line, the researchers added. "Time and productivity lost due to chronic diseases associated with overweight and obesity may make it financially worthwhile for employers to be more proactive in the health of their employees by promoting physical activity at work," they wrote.
