| a Children are considered to have moderate to severe health problems if their parent reported that a doctor had ever told them that their child had one of 16 health conditions included in the survey, and the parent characterized that condition as being either moderate or severe at the time of the interview. The specific health conditions include: learning disabilities; Attention Deficit Disorder or Attention Deficit with Hyperactivity Disorder; depression, anxiety problems, behavior or conduct disorders; Autism or Autism Spectrum Disorder; developmental delay; speech problems such as stuttering or stammering; asthma, diabetes, Tourette Syndrome, epilepsy or other seizure disorder; hearing problems; vision problems that cannot be corrected with glasses or contact lenses; bone, joint, or muscle problems; and brain injury or concussion. Some conditions were not assessed for children under age 3. In addition, relatively small samples and low prevalence of conditions among children ages 3–5 made a separate breakout of this age group infeasible. |
