The number of health savings accounts and health reimbursement arrangements increased in 2010, but average individual account balances fell, according a report from the Employee Benefit Research Institute.
Those who exercised, didn't smoke and were not obese had higher account balances than those whose behaviors weren't as healthy.
The number of HSAs and HRAs, which are used to reimburse participants for qualified medical expenses, increased to 5.7 million in 2010, from 1.2 million in 2006, according to the report.
Assets in the plans jumped to $7.7 billion in 2010, from $835.4 million in 2006.
Yet the report found the average account balance dropped in 2010 to $1,355, from $1,419 in 2009.
While the average individual rollover amount in 2010 declined, total assets being rolled over have been increasing: $4.2 billion was rolled over in 2010, versus $4 billion in 2009.
The average individual rollover increased from $592 in 2006 to $1,295 in 2009, before falling to $1,029 in 2010.
