To examine disparities in the prevalence of the limitation of activity caused by chronic conditions or disability for black and white non-Hispanic children and to examine trends over time in the prevalence of disability.
We analyzed data on 419,843 children (22,758 with a disability) younger than 18 years included in 14 annual editions of the National Health Interview Survey spanning the period 1979-2000.
Noninstitutionalized population in the United States.
None.
Prevalence of disability.
The prevalence of disability increased markedly for both black and white children between 1979 and 2000. Bivariate analysis demonstrated racial differences that fluctuated through time, but persisted through 2000, with black children experiencing a higher prevalence of disability than white children. Multivariate analyses conducted on the 1999-2000 data indicated that the black-white difference in disability prevalence could be explained entirely by differences in poverty status.
Black children have higher rates of disability primarily owing to their increased exposure to poverty.
研究非西班牙裔黑人和白人儿童中由慢性病或残疾导致的活动受限患病率的差异，并考察残疾患病率随时间的变化趋势。
我们分析了1979年至2000年期间14期《国家健康访谈调查》中纳入的419,843名18岁以下儿童（22,758名残疾儿童）的数据。

无。
残疾患病率。
1979年至2000年期间，黑人和白人儿童的残疾患病率均显著上升。双变量分析显示种族差异随时间波动，但一直持续到2000年，黑人儿童的残疾患病率高于白人儿童。对1999 - 2000年数据进行的多变量分析表明，残疾患病率的黑白差异完全可以由贫困状况的差异来解释。
黑人儿童残疾率较高主要是因为他们更多地面临贫困。
