Blue-collar workers are top of the list for worst employee health, according to a recent survey conducted by Gallup-Healthways.

The survey found that 33 percent of mining and construction workers and 29 percent of installation and repair employees are smokers, reported USA Today.

Running in the 30 percentile for obesity are those employed in transportation, manufacturing and production. Fresh fruits and vegetables are hardly found in the diet of half of the construction and mining workers surveyed, according to the report.

Better health will cause less turnover and lower health care costs for companies, said Carter Coberley, director of Health Research and Outcomes at Healthways to USA Today.
