A 10-year follow-up of 297 survivors from a community study of the aged found (a) there was little or no decline in social and economic function and only moderate declines in mental, physical, and activities-ofdaily-living function; (b) demographic and socioeconomic characteristics were usually strong predictors of decline in function; and (c) impairments in one type of function often predicted greater decline in other types of function. Mental impairment was an especially strong predictor of social decline, but not vice versa.
