Today persons age 65 years and older currently represent a little more than one-third of the patients seen by a primary care physician; in 40 years, we can safely predict that at least every other adult patient will age 65 or older. The “old-old” (older than 85), however, are the most rapidly growing group of older individuals, with a growth rate twice that of those age 65 years and older and four times that of the total population. This group now represents approximately 10% of the older population and is anticipated to grow from 5.7 million in 2010 to over 19 million by 2050 (Day, 1993). Among this old-old group those age 90 and above will show the steepest population rise (Federal Interagency Forum on Aging-Related Statistics, 2010). People in this old-old group tend to have poorer physical activity, be more dependent in activities of daily living, and have more cognitive impairment (Zhao et al., 2010).
