Background and Objectives Successful aging has been described as a multifactorial and dynamic process. The aims of the study were to detect aging trajectories of physical function and behavioral, psychological and social well-being; and to explore the correlations between functional versus well-being trajectories by age group. Research Design and Methods Data were gathered from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K, N=1375). Subjects’ physical function was assessed through walking speed and chair stand tests, behavioral well-being through participation in mental and physical activities, psychological well-being through life satisfaction and positive affect, and social well-being through social connections and support. All exposures were standardized (z-scores). Linear mixed models were used to estimate trajectories of physical function and well-being over a 12-year follow-up. Results The steepest declines were seen for physical function (relative change in z-scores across ages; RC=3.01), followed by behavioral well-being (RC=2.15), psychological well-being (RC=2.01) and social well-being (RC=0.76). Correlations between physical function and the different well-being domains were weak, especially for slopes. Stronger intercept correlations were observed among the oldest- compared to the youngest-old, especially with behavioral (r=0.39 vs r=0.24) and psychological (r=0.33 vs r=0.22) well-being. Discussion and Implications Physical function declines the fastest throughout aging. The different well-being domains decline at a slower rate, which may be a possible sign of compensation against age-related functional decline, especially among the youngest-old, for whom discordances between physical function and the different well-being domains were more common. |
