The role of instrumental activity of daily living disability in the association between circadian syndrome and cardiometabolic multimorbidity in Chinese middle-aged and older adults

Key Points

• New-onset cardiometabolic multimorbidity is linked to circadian syndrome and IADL disability, highlighting a critical connection.
• IADL disability accounts for 8.37% of the effect of circadian syndrome on cardiometabolic multimorbidity progression.
• This research emphasizes the role of functional disabilities in understanding cardiometabolic conditions among older adults.
• Addressing IADL disability may contribute to the prevention of cardiometabolic multimorbidity in middle-aged and older adults.
