To investigate heterogeneous trajectory of sarcopenia and its associated factors among older adults with multimorbidity.
Based on the Asian Working Group for Sarcopenia 2019 Consensus, three waves of data in 2011, 2013, and 2015 from the China Health and Retirement Longitudinal Study were utilized. Latent growth mixture model and multinomial logistic regression were selected to identify heterogeneous sarcopenia trajectories and associated factors among older adults with multimorbidity.
Of the 1 254 participants, four heterogeneous trajectories of sarcopenia were identified: high initial but sharply declining trajectory (7.5%,n=93), low and stable change trajectory (64.0%, n=803), high and stable change trajectory (23.5%, n=295), low initial but sharply increasingtrajectory (5.0%, n=63). Disability, body mass index (BMI), cognition, sleep duration, smoking habits, and alcohol consumption were associated with different sarcopenia trajectories.
There are heterogenous sarcopenia trajectories among older adults with multimorbidity, targeted intervention regarding disability, BMI, cognition, sleep, smoking, and drinking should conducted to prevent sarcopenia.
