Outline of Final Research Achievements

Among 1524 adults aged 65 years or older who participated in a baseline survey, 1048 adults (mean [SD] age, 71.6 [5.4] years; women, 57.0%) were followed-up at least once. The total number of observations was 4,747, and the average number of follow-up assessments was 4.5 during the period from 2002 through 2010. We checked local registries to identify deaths from any cause; 89 (8.5%) participants died until 2011.
We identified 3 distinct trajectory patterns (high, middle, and low trajectory groups) for each PPM (hand-grip strength, usual gait speed, and one-leg standing time) in adults aged 65 to 90 years, and the trajectories for hand-grip strength and usual gait speed showed parallel declines in men and women, respectively. Adults in the low trajectory group were more likely to be lower BMIs, hemoglobin A1c values, albumin levels, TMIG-IC scores, and scores.
