BACKGROUND: Cognitive frailty (CF) is of concern because of its high prevalence in older population and its close association with adverse health outcomes. However, interventions against CF in China are relatively simple. Therefore, the purpose of this study was to analyse the effects of comprehensive interventions on CF in community-dwelling older adults. METHODS: 225 participants, including 108 individuals with reversible CF (RCF) and 117 individuals with potentially RCF (PRCF) were recruited and divided into intervention and control groups. Participants in RCF Intervention Group underwent primary intervention, and participants in PRCF Intervention Group underwent secondary intervention. CF reversal rate and MoCA score were recorded. RESULTS: Primary intervention and secondary intervention could well reversed CF. Additionally, MoCA scores changed significantly. CONCLUSIONS: Adhering to regular comprehensive interventions can effectively reverse CF for community-dwelling older adults. Additionally, RCF maybe is an effective target for reversing CF via early intervention.
