The growth in health insurance premiums slowed for the fourth consecutive year and grew at its lowest level since 1999, but it still outpaced both worker’s earnings and inflation. In an annual national survey of public and private employers with three or more workers, The Kaiser Family Foundation and the Health Research and Educational Trust found that between the spring of 2006 and 2007 premiums rose an average of 6.1 percent for employer sponsored health insurance, a drop from the 7.7 percent increase during the same period a year ago. That compares to a 3.7 percent in workers’ earnings and a 2.6 percent rise in inflation. The survey also found on average workers are contributing 7.9 percent more for their health premiums from a year ago to cover a family of four.
