Survey Items: K2Q31A-B; K2Q32A-B; K2Q33A-B; K2Q34A-B; K2Q35A-B; K2Q36A-B; K2Q37A-B; K2Q38A-B; K2Q40A-B; K2Q41A-B; K2Q42A-B; K2Q43A-B; K2Q44A-B; K2Q45A-B; K2Q46A-B; K2Q60A-B; K2Q61A-B
Denominator: Children age 0-17 years
Numerator: No current health conditions; one current health condition; two or more current health conditions
Revisions and Changes: Although root questions K2Q30-K2Q46 were not changed in 2007, current prevalence is new. In 2011/12, the prevalence of intellectual disability (K2Q60A-B) and cerebral palsy (K2Q61A-C) were newly added. In both surveys conditions were named and parents were asked to respond for each condition whether they had ever been told by a health professional that their child had the condition. If yes, they were asked whether the child currently had the specific condition.
Additional Notes: Indicator 1.9a is derived from responses to two questions about each of 18 acute or chronic health conditions: learning disability (K2Q30A-B), ADD or ADHD (K2Q31A-B), depression (K2Q32A-B), anxiety problems (K2Q33A-B), behavioral or conduct problems (K2Q34A-B), autism or other autism spectrum disorder (K2Q35A-B), developmental delay (K2Q36A-B), intellectual disability (K2Q60A-B), cerebral palsy (K2Q61A-C), speech problems (K2Q37A-B), asthma (K2Q40A-B), diabetes (K2Q41A-B), Tourette Syndrome (K2Q38A-B), epilepsy or seizure disorder (K2Q42A-B), hearing problems (K2Q43A-B), vision problems (K2Q44A-B), bone or joint problems (K2Q45A-B), and brain injury or concussion (K2Q46A-B). For each condition, respondents were asked whether they have ever been told by a health care professional that the child has the condition, and whether the child currently has the condition. Children were then grouped according to the number of conditions they currently have: none, one, or two or more. Please note that in the NSCH all information about children's health conditions is based on parent recollection and is not independently verified. Further, a response of "Yes" to having "ever been told" that a child has a specific health condition (e.g., K2Q31A = Yes) DOES NOT indicate whether the child currently has that particular condition and therefore should not be interpreted as current prevalence.
Treatment of Unknown Values: Unknown values (responses coded as 'refused', 'don't know', or system missing) are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the data query results table. In nearly every case, the proportion of unknown values is less than 1% and the exclusion of these values does not change the prevalence estimates (%) and only marginally affects the weighted population counts (Weighted Est.). Exceptions are noted in the form of a “Data Alert” at the bottom of a results table.
History and Development: The Maternal and Child Health Bureau leads the development of the NSCH survey and indicators, in collaboration with the National Center for Health Statistics (NCHS) and a national technical expert panel. The expert panel includes representatives from other federal agencies, state Title V leaders, family organizations, and child health researchers. Previously validated questions and scales are used when available. Respondents’ cognitive understanding of the survey questions is assessed during the pretest phase and revisions made as required. All final data components are verified by NCHS and DRC/CAHMI staff prior to public release. The samples in 2003 and 2007 were drawn by random digit dial telephone sampling. The 2011/12 survey included the addition of cell phones to the sample. This has implications for the comparability of items between 2007 and 2011/12.

C.I. = 95% Confidence Interval. Percentages and population estimates (Pop.Est.) are weighted to represent child population in US.
