"The CBO projects that 14 million people will become newly insured next year under the [ACA] and 25 million will gain coverage by 2016. These historic gains in health insurance coverage are likely to have variable effects on the health of newly insured people over the next several years, with the sickest and the oldest realizing more immediate changes in health status. But even those changes may not show up as dramatic improvements in health, but rather as the preservation of good health, or a slowing of its deterioration."
