Objective

To explore the transition patterns of latent classes of intrinsIC capacity (IC) and their associations with adverse health outcomes in community-dwelling older adults.

Methods

A convenience sample of 512 older adults from Lishui, Zhejiang was followed for one year (T1, T2). Latent transition analysis was used to identify IC latent classes and analyze their transition patterns.

Results

Three IC latent classes were identified: low IC (T1: 19.14%), moderate IC (43.75%), and high IC (37.11%). IC classes remained relatively stable over one year, with transitions mainly occurring between adjacent classes: 9.2% of low IC improved to moderate IC;14.3% of moderate IC improved to high IC while 7.1% deteriorated to low IC; and 15.8% of high IC declined to moderate IC. Chi-square tests revealed that persistent low IC (χ2=5.986, P<0.05) or moderate IC (χ2=0.044, P<0.05), and transition from high to moderate IC (χ2=0.015, P<0.05) were associated with recurrent falls (≥2 times). Transition from moderate to low IC increased hospitalization risk (χ2=5.042, P<0.05).

Conclusion

IC latent classes demonstrate relative stability in community-dwelling older adults over one year, with predominant transitions between adjacent classes. These transitions are signifICantly associated with risks of falls and hospitalization.
