Several measures of old age disability and limitations have shown improvements in the last decade. Research into the causes of these improvements is needed to understand the implications for the future demand for medical care.

The number of US adults ages sixty-five and older who are living with dementia is substantial and expected to grow, raising concerns about the demands that will be placed on family members and other unpaid caregivers. We used data from the 2011 National Health and Aging Trends Study and its companion study, the National Study of Caregiving, to investigate the role of dementia in caregiving. We found that among family and unpaid caregivers to older noninstitutionalized adults, one-third of caregivers, and 41 percent of the hours of help they provide, help people with dementia, who account for about 10 percent of older noninstitutionalized adults. Among older adults who receive help, the vast majority in both community and residential care settings other than nursing homes rely on family or unpaid caregivers (more than 90 percent and more than 80 percent, respectively), regardless of their dementia status. Caregiving is most intense, however, to older adults with dementia in community settings and from caregivers who are spouses or daughters or who live with the care recipient.

In September 2002, a technical working group met to resolve previously published inconsistencies across national surveys in trends in activity limitations among the older population. The 12-person panel prepared estimates from five national data sets and investigated methodological sources of the inconsistencies among the population aged 70 and older from the early 1980s to 2001. Although the evidence was mixed for the 1980s and it is difficult to pinpoint when in the 1990s the decline began, during the mid- and late 1990s, the panel found consistent declines on the order of 1%-2.5% per year for two commonly used measures in the disability literature: difficulty with daily activities and help with daily activities. Mixed evidence was found for a third measure: the use of help or equipment with daily activities. The panel also found agreement across surveys that the proportion of older persons who receive help with bathing has declined at the same time as the proportion who use only equipment (but not personal care) to bathe has increased. In comparing findings across surveys, the panel found that the period, definition of disability, treatment of the institutionalized population, and age standardizing of results were important to consider. The implications of the findings for policy, national survey efforts, and further research are discussed.
