Denominator: Children age 0-17 years

Numerator: Does not have any current or lifelong health conditions; Has 1 current or lifelong health condition; Has 2 or more current or lifelong health conditions

Revisions and Changes: There have been changes in this measure since 2016. The number of conditions included in the composite may have changed year to year due to conditions being added to or removed from the survey. Changes may also include the way the item was worded, in the response options provided, or in other areas such as a skip pattern change, question placement changes, etc. For more information about the changes click here

Additional Notes: This measure was scored as the count of current or lifelong health conditions the child experiences from a list of 24 conditions asked in the 2021 NSCH and 25 conditions asked in the 2022 NSCH. These conditions include allergies (food, drug, insect or other), arthritis (2021), asthma, autoimmune disease (such as Type 1 Diabetes, Celiac or Juvenile Idiopathic Arthritis; 2022), blood disorders (such as sickle cell disease, thalassemia, or hemophilia), cerebral palsy, cystic fibrosis, diabetes (2021), Type 2 Diabetes (2022), Down Syndrome, Fetal Alcohol Spectrum Disorder (2022), epilepsy or seizure disorder, genetic or inherited condition, heart condition, frequent or severe headaches including migraine (3-17 years), Tourette Syndrome (3-17 years), anxiety problems (3-17 years), depression (3-17 years), behavioral and conduct problem (3-17 years), developmental delay (3-17 years), intellectual disability (3-17 years), speech or other language disorder (3-17 years), learning disability (3-17 years), autism or autism spectrum disorder (ASD; 3-17 years), attention deficit disorder or attention-deficit/hyperactivity disorder (ADD or ADHD; 3-17 years), hearing problems, and vision problems. In most cases, in order to be counted towards a current or lifelong condition, parents had to answer “Yes” to two questions about the particular condition: 1) have you ever been told by a health care professional or educator that the child has the condition, and 2) does this child currently have the condition. However, children who were ever told by a health care professional that they had autoimmune disease (2022), blood disorders, cerebral palsy (2022), cystic fibrosis, genetic or inherited conditions, or Down Syndrome were counted toward the measure as these were considered lifelong conditions. The questions about hearing and vision problems were reported by parents on whether the child has “deafness or problems with hearing” or “blindness or problems with seeing, even when wearing glasses.”
Please note that throughout the NSCH, all information about children's health conditions is based on parent recollection and is not independently verified.

Treatment of Unknown Values: Missing values may be due to non-response (i.e. a skipped item) or a “don’t know” response. The way these items are handled can vary by measure. For NPMs and NOMs, having missing values for all items in an indicator will lead to the case being given a missing value on the overall measure. For some other measures, if there is a missing value on any of the items, the case will be set to missing. How missing values are handled is documented in the "Additional notes" field above when required.
Missing values are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the Interactive Data Query results table. In the majority of cases, the proportion of missing values is less than 2%. Exceptions are noted in the form of a Data Alert at the bottom of a results table. The exclusion of these values does not change the prevalence estimates (%) and only marginally affects the weighted population counts (Pop. Est.).

About NSCH
The National Survey of Children’s Health (NSCH), funded and directed by the Health Resources and Services Administration’s (HRSA) Maternal and Child Health Bureau (MCHB), is designed to provide annual national and state-level information on the health and well-being of children ages 0-17 years in the United States. The U.S. Census Bureau administers the survey, oversees the sampling, and produces a final data set of survey results. HRSA’s Maternal and Child Health Bureau (MCHB) develops survey content in collaboration with the U.S. Census Bureau and a Technical Expert Panel. The Technical Expert Panel consists of experts in survey methodology and children’s health, federal and state stakeholders, clinicians and researchers. In 2016, the NSCH underwent a significant redesign which combined content from both the NSCH and the National Survey of Children with Special Health Care Needs (NS-CSHCN). Further information on that redesign can be found in “The Design and Implementation of the 2016 National Survey of Children’s Health”.
The NSCH is conducted as a household survey, and one child per household is selected to be the subject for the detailed age-specific questionnaire. The respondent to this questionnaire is a parent or guardian who is living in the home and has knowledge of the sampled child. Survey participants complete either web-based or self-administered paper-and-pencil questionnaires. Data from the NSCH is used for scientific research, federal policy and program development, and state-level planning and performance reporting. Information is collected on factors related to the health and well-being of children, including access to and utilization of health care, receipt of care in a medical home, systems of care for CSHCN, family interactions, parental health, school and after-school experiences, and neighborhood characteristics.
More information about the survey can be found in the “About the National Survey of Children's Health” section of this website and HRSA’s MCHB website.
