Abstract
Self-perceptions of aging (SPA) is associated with various health-related outcomes, including physical performance. No previous study has investigated the potential predictive influence of SPA on physical performance among Swedish community-dwelling older adults. This was a cross-sectional study using a random sample of 153 Swedish community-dwelling individuals aged 70 and older. Multiple logistic regression analysis was performed, using the subscale “Attitude Towards Own Aging” of the Philadelphia Geriatric Center Morale Scale, as a measure of SPA. The Short Physical Performance Battery (SPPB) was dichotomized and used as the outcome variable. SPA was a significant predictor (OR = 1.546, CI = 1.066–2.243) of physical performance, adjusted for age, cognitive function, and life-space mobility. Further analyses revealed significant sex differences, with SPA not being included in the model for the men whilst it was still a significant predictor (OR = 1.689, CI = 1.031–2.765) of physical performance in the group of women. SPA plays a significant role in predicting physical performance among Swedish community-dwelling older adults. To further clarify this relationship and its consequences, future longitudinal research should focus on the relationship between SPA, physical performance, and fall risk.
Highlights
The purpose of this study is to investigate if self-perceptions of aging can act as an independent predictor of physical performance, among Swedish community-dwelling older adults
The aim of this study was to investigate if self-perceptions of aging (SPA) could act as an independent predictor of objectively measured physical performance among Swedish community-dwelling older adults
We found that Self-perceptions of aging (SPA) plays a significant role in predicting physical performance, which is in line with previous research [14,21,22,23]
Summary
The proportion of older individuals is increasing faster than any other age group [1]. As approximately 15% of the total population is constituted by individuals aged 70 and older [2] and is projected to be double that by. To do so, maintaining functional ability such as physical performance is of great importance [3]. The process of aging is associated with a decline in muscle mass which can lead to diminished musculoskeletal function and strength. Agerelated decline in physical functions such as gait speed, leg strength, and balance have been associated with fall prevalence and reoccurrence [5] as well as with fall-related concern [6,7]
