Premiums for employer-sponsored health insurance rose 5% this year, to $12,680 a year for family coverage.
Employees were paying an average of $3,354 to cover their share of the costs, according to researchers at the Henry J. Kaiser Family Foundation, Menlo Park, Calif., and the Health Research & Educational Trust, Washington.
The researchers based the figures on results of a survey, conducted between January and May, that included 2,832 non-federal public and private firms with 3 or more employees.
The percentage of workers with deductibles of $1,000 or higher has increased to 18%, from 12% in 2007, the researchers report.
The percentage of workers in high-deductible plans has increased to 35% at employers with 3 to 199 workers, from 21% in 2007.
For workers facing deductibles in preferred provider organization plans, the average deductible rose to $560, up about $100 from the 2007 average.
