Patterns of intrinsic capacity among community-dwelling older adults: Identification by latent class analysis and association with one-year adverse outcomes

Abstract

ObjectiveTo identify patterns of intrinsic capacity (IC) and determine the association between these patterns with incident one-year outcomes. MethodsA total of 756 older adults aged ≥ 60 years were followed up after 1 year. IC was assessed using the revised integrated care for older people screening tool, and its patterns were examined by the latent class analysis. Logistic regression models were conducted to compare the risk of adverse outcomes. ResultsThree IC patterns were identified. Both “sharp declines in sensory domain” (Class 2) and “sharp declines in locomotion, psychological, cognition and vitality domains” (Class 3) were at greater risk of disabilities and poor physical quality of life than “relatively healthy” (Class 1). The Class 3 was twice as likely to be hospitalized as Class 1. DiscussionAssessment of IC could provide valuable information on stratifying older adults into heterogeneous groups, promoting targeted interventions to delay the adverse outcomes.
