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.
自我衰老感知（SPA）与各种健康相关的结果有关，包括身体表现。以前没有研究调查 SPA 对瑞典社区居住的老年人身体表现的潜在预测影响。这是一项横断面研究，使用了随机抽取的 153 名瑞典社区居住的 70 岁及以上的个体的样本。使用费城老年医学中心士气量表的“对自身衰老的态度”分量表作为 SPA 的衡量标准，进行了多项逻辑回归分析。短体物理表现电池（SPPB）二分法并用作结果变量。调整年龄、认知功能和生活空间移动性后，SPA 是身体表现的显著预测因素（OR=1.546，CI=1.066-2.243）。进一步的分析显示存在显著的性别差异，男性模型中不包括 SPA，而女性模型中 SPA 仍然是身体表现的显著预测因素（OR=1.689，CI=1.031-2.765）。SPA 在预测瑞典社区居住的老年人身体表现方面起着重要作用。为了进一步阐明这种关系及其后果，未来的纵向研究应关注 SPA、身体表现和跌倒风险之间的关系。
