Covering Kids and Families of Indiana is encouraging Hoosier adults and children to take advantage of free health care options before school starts.The organization is sponsoring health screenings and immunizations, and they're also telling parents and their children how to sign up for S-CHIP or Medicaid insurance plans.Organization Executive Director David Roos says poor health can lead to poor academic performance."If a child isn't healthy then they might not even show up to school. But if they do show up to school and they've got problems with their eyesight, problems with asthma or problems with obesity they're less likely to be successful in school," he says.Roos says there are more than 131 thousand children in Indiana who are uninsured, and many of them qualify for Medicaid or SCHIP.
