QuickStats: Percentage of Children Aged <18 Years with an Impairment or Health Problem That Limits Crawling, Walking, Running, or Playing, by Age Group and Poverty Status* --- National Health Interview Survey (NHIS), United States, 2001--2007

The figure shows the percentage of children aged <18 years with an impairment or health problem that limits crawling, walking, running, or playing, by age group and poverty status from the National Health Interview Survey (NHIS) from 2001-2007. During 2001-2007, children aged 12-17 years were more likely than younger children to have an impairment or health problem that limited crawling, walking, running, or playing. The prevalence of such impairments or problems generally declined as poverty status decreased.

* For each survey year, poverty status is based on the ratio of the family's income to federal poverty levels, as calculated by the U.S. Census Bureau. In addition to family income, federal poverty levels take into account family size and the number of children in the family. A larger ratio of income relative to poverty level indicates increasing family income and thus decreasing poverty status. Because of high levels of missing income data in NHIS, poverty status was determined from the 2001--2007 NHIS multiple imputed income and earnings data files.

Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. population. One child aged <18 years was randomly selected per family; a knowledgeable adult provided information for each child. Prevalence of impairments or health problems resulting in activity limitations is based on a question that asked, "Does [the sample child] have an impairment or health problem that limits [his/her] ability to crawl, walk, run, or play?" Unknowns with respect to impairments are excluded from the denominators.
