QuickStats: Percentage of Persons with Activity Limitation Caused by
a Chronic Condition,* by Poverty Level Status and Race/Ethnicity
--- National Health Interview Survey, United States,
2006†
* Activity limitation was determined by responses to a series of questions regarding 1) limitations in a person's ability to engage in work, school, play, or other
activities because of health reasons; 2) specific conditions causing the limitations; and 3) the duration of the conditions. Those conditions lasting >3 months were classified
as chronic; selected conditions (e.g., arthritis, diabetes, cancer, heart conditions) were considered chronic regardless of duration.
† Estimates were based on family interviews of a sample of the civilian, noninstitutionalized U.S. population and age-adjusted to the 2000 standard population
using six age groups: <18 years, 18--44 years, 45--54 years, 55--64 years, 65--74 years, and
>75 years.
§ Poverty level is based on family size and income.
¶ 95% confidence interval.
In 2006, persons with lower family incomes were more likely to report activity limitation because of a
chronic condition than persons with higher family incomes. Among persons at the lowest income level, non-Hispanic
whites (25.7%) were more likely to report limitations than non-Hispanic blacks (22.5%) and Hispanics (15.7%).
