Who's at risk for CTDs?

When scientists study the cause of diseases, one of the first questions they ask is, "Who is at risk?" The National Association of Working Women estimates that over 50 million computer workstations exist in offices across the country, or two computers for every three white-collar workers.

Census Bureau statistics show that 52 percent of women and 40 percent of men used VDTs on their jobs in 1993.

Not everyone who uses a computer is at risk for developing a CTD. But studies show that computer users complain more about eyestrain, neck aches and backaches than workers in similar jobs without computers.

While no precise formulas can dictate just how much computer work it takes to develop a CTD, many positive steps can be taken to reduce the risk of developing these disorders.
