Table 2 shows subject characteristics by survival status. Although height and weight were similar between those who did and did not survive the 12 year follow-up period, there were statistical differences between groups in several of the study variables – namely, age, sex, disability and mobility scores, and total activity score. The average total activity score was 2.62 among the survivors and 2.11 among the non-survivors. For reference, obtaining a median score of 2 could be accomplished by participating in a single activity, such as walking, "often in the past month". This low frequency of reported activity is consistent with other data for older populations.
