Female employees and male andfemale managers are the most at risk for gaining weight on the job,according to a survey by CareerBuilder.

The recruitment firm came to that conclusion after seeking inputfrom more than 3,000 employees. More than half self-reported asoverweight, and 39% claim they've gained weight at their currentjob. Forty-five percent said their weight has stayed the same,while 16% reported weight loss.

Of those reporting weight gains, one in five said they'd gained10 pounds, and one in 10 reported putting on 20 pounds.

Women workers reported a higher incidence of weight gain thanmen — 46% v. 33%. More than half of the men and women surveyed saidthey exercise regularly, with the male reported percentage slightlyhigher (59% v. 56%).

Managers say they tend to put on the pounds more often than dothe direct reports (44% of bosses compared to 38% ofnon-managers).

Older workers gain more than do younger workers — no surprisethere – “with 40% of workers ages 35 and older gaining weight,compared to 36% of those under 35 years of age. Eighteen- to24-year-olds were the least likely, with 30% saying they put onextra pounds,” the report said.

And, despite all the opportunities for outdoor activity way outWest, workers in that part of the country “were the most likely topack on pounds, with 44% saying they've put on weight at theircurrent job. They were followed by the Northeast (40%), the South(37%) and the Midwest (37%).”
