The objective of this study was to examine correlates of discordance between 13-year trajectories of self-reported functional limitations and performance-based physical functioning in older adults. We included 2,135 participants from the population-based Longitudinal Aging Study Amsterdam, the Netherlands, followed across 1995-2008. Self-reported functional limitations included six (instrumental) activities of daily living. Performance-based functioning was a composite of four tests. We used latent class growth analysis and multinomial logistic regression to examine discordance and its correlates. Patterns of discordance and concordance (41% concordance, 46% "overestimation" of daily functioning, 13% "underestimation") appeared to be persistent over 13 years. Older age, male sex, cognitive impairment, absence of pain, and light alcohol use were associated with overestimation. Younger age, female sex, and lower self-rated health were associated with underestimation. Factors associated with overestimation partly differ from those associated with underestimation. Factors that are highly stable over time are particularly good indicators of persistent discordance.
本研究旨在探讨老年人自我报告的功能障碍与基于表现的身体功能之间 13 年轨迹不一致的相关因素。我们纳入了来自荷兰阿姆斯特丹纵向老龄化研究的 2135 名参与者，该研究在 1995 年至 2008 年期间进行了随访。自我报告的功能障碍包括六项（工具性）日常生活活动。基于表现的功能是四项测试的综合。我们使用潜在类别增长分析和多项逻辑回归来检查不一致性及其相关因素。不一致和一致的模式（41%的一致性，46%的日常功能“高估”，13%的“低估”）似乎在 13 年内持续存在。年龄较大、男性、认知障碍、无疼痛和轻度饮酒与高估有关。年龄较小、女性和自我报告的健康状况较低与低估有关。与高估相关的因素与与低估相关的因素部分不同。在较长时间内高度稳定的因素是持久不一致的良好指标。
