Changes in muscle health measures and diet quality indices between baseline and 15-year follow-up. a A significant decrease was observed in participants’ skeletal muscle index between baseline and 15 years. b Timed up-and-go scores were significantly slower at 15 years compared to baseline. c Participants’ Australian Recommended Food Scores remained consistent over the 15-year period with R²=0.41 between the two time points. d Minor changes were observed between Dietary Inflammatory Index scores between baseline and 15 years with R²=0.24
