    The age-specific prevalence, risk factors, and magnitude of the association between cognitive frailty and mortality in middle-aged and older adults remains unclear. We used baseline (2011) and follow-up wave (2013, 2015, and 2018) data from the China Health and Retirement Longitudinal Study (CHARLS). The age group was categorized as middle-aged, old, and very old. Factors associated with cognitive frailty and the associations between cognitive fr…

  • Association of Sleep and Physical Activity Among Older Adults and the Moderation of Chronotype

    Open AccessJing Huang, Mengchi Li et al.ARTICLEThe International Journal of…2023

    This study aimed to examine the associations of both subjectively and objectively measured sleep with physical activity among older adults and to explore the possible moderating role of chronotype in these associations.

Pittsburgh Sleep Quality Index and Actigraphy were used as subjective and objective sleep measures, respectively. Physical…
