Physical behaviour profiles and their associations with fitness and function in older adults: a cross-sectional latent profile analysis

Distinct physical behaviour profiles exist among older Portuguese adults. Profiles characterised by lower SB and higher LPA, even when not fully meeting MVPA recommendations ("intermediate movers"), were associated with better physical fitness and physical function compared to the "highly sedentary" profile. This underscores the importance of reducing SB and promoting LPA along with MVPA. By uncovering these behavioural profiles among older adults, latent profile analysis provides valuable insights to guide the development of more personalized interventions for healthy ageing.
