Restricted activity, defined as staying in bed for at least half a day or cutting down on one's usual activities because of an illness or injury (1), has high face validity as a measure of health and functional status, especially for older persons, who often value quality of life over longevity (2). The importance of restricted activity was recognized more than 20 years ago in the U.S. Surgeon General's original Healthy People Report (3), which identified reduction of restricted activity as one of its two major goals for older persons. Subsequently, several clinical trials of preventive interventions have included restricted activity as a key outcome measure (4-7).
