Older adults show three distinct paths of oral frailty

In a prospective study of 295 older adults living in six Chinese long-term care facilities, researchers tracked oral frailty across six months. Oral frailty reflects progressive functional decline linked to broader health deterioration in late life. Investigators assessed participants using the Oral Frailty Index-8 at baseline and at 1-, 3-, and 6-month follow-ups, applying latent growth mixture modelling to capture progression patterns. The analysis identified three distinct trajectories among residents. A low-level persistent stable group accounted for 46.3% of participants, while 34.4% followed a moderate-level gradual recovery path. The remaining 19.3% exhibited high-level progressive deterioration. Key clinical markers distinguishing the three groups included cognitive impairment, nutritional status, insomnia, the number of chronic conditions, and long-term alcohol consumption.
