(Reuters) - If uninsured young Americans shun the new health plans offered under President Barack Obama's healthcare reform law, it will be because the insurance costs too much and not because they don't expect to need much medical care, according to a study released on Wednesday. What uninsured young adults do when state exchanges created under "Obamacare" open on October 1 will be one of the most important factors in determining the success of the president's signature domestic policy achievement. If too few young people, who tend to be relatively healthy, sign up for coverage, then premiums might not cover the medical costs of sicker people who do enroll.
