Abstract

Cognitive impairment and low muscle mass are prevalent conditions in later life, and each has been independently associated with adverse health outcomes. Both conditions are heterogeneous and may arise from multiple underlying etiologies. However, evidence regarding their combined association with all-cause mortality remains limited, particularly among older adults in China. Therefore, this study aimed to investigate the independent and joint associations of cognitive impairment and low muscle mass with all-cause mortality using data from a large prospective cohort.

Research summary

The paper investigates the independent and joint associations of cognitive impairment and low muscle mass with all-cause mortality among older adults. This study is relevant as it addresses factors that contribute to mortality in aging populations, although it does not directly tackle the root causes of aging itself.
