BACKGROUND: To examine concurrent prevalence trends of chronic disease, impairment and disability among older adults.

METHODS: We analyzed the 1998, 2004 and 2008 waves of the Health and Retirement Study, a nationally representative survey of older adults in the United States, and included 31,568 community dwelling adults aged 65 and over. Measurements include: prevalence of chronic diseases including hypertension, heart disease, stroke, diabetes, cancer, chronic lung disease and arthritis; prevalence of impairments, including impairments of cognition, vision, hearing, mobility, and urinary incontinence; prevalence of disability, including activities of daily living (ADLs) and instrumental activities of daily living (IADLs).

RESULTS: The proportion of older adults reporting no chronic disease decreased from 13.1\% (95\% Confidence Interval [CI], 12.4\%-13.8\%) in 1998 to 7.8\% (95\% CI, 7.2\%-8.4\%) in 2008, whereas the proportion reporting 1 or more chronic diseases increased from 86.9\% (95\% CI, 86.2\%-89.6\%) in 1998 to 92.2\% (95\% CI, 91.6\%-92.8\%) in 2008. In addition, the proportion reporting 4 or more diseases increased from 11.7\% (95\% CI, 11.0\%-12.4\%) in 1998 to 17.4\% (95\% CI, 16.6\%-18.2\%) in 2008. The proportion of older adults reporting no impairments was 47.3\% (95\% CI, 46.3\%-48.4\%) in 1998 and 44.4\% (95\% CI, 43.3\%-45.5\%) in 2008, whereas the proportion of respondents reporting 3 or more was 7.2\% (95\% CI, 6.7\%-7.7\%) in 1998 and 7.3\% (95\% CI, 6.8\%-7.9\%) in 2008. The proportion of older adults reporting any ADL or IADL disability was 26.3\% (95\% CI, 25.4\%-27.2\%) in 1998 and 25.4\% (95\% CI, 24.5\%-26.3\%) in 2008.

CONCLUSIONS: Multiple chronic disease is increasingly prevalent among older U.S. adults, whereas the prevalence of impairment and disability, while substantial, remain stable.
