The interplay of multimorbidity and depressive symptoms: mediation role of functional dependence

Q: What are the key findings of this study?

Multimorbidity and depressive symptoms exhibited bi-directional associations over 8 years, with functional dependence mediating 9-21% of the link for cardiometabolic diseases.

Does functional dependence mediate the bi-directional relationship between multimorbidity and depressive symptoms in Chinese adults?

Bi-directional links between multimorbidity and depressive symptoms, and the mediation role of functional dependencepatient reported

Functional dependence mediates the bi-directional relationship between multimorbidity (especially cardiometabolic diseases) and depressive symptoms in Chinese adults.

Limitaciones

Self-reported physician diagnoses or medical treatments may underestimate multimorbidity prevalence.
Severity of chronic conditions was not taken into consideration.
Measure of functional dependence was restricted to basic ADLs, not capturing instrumental ADLs (IADL).
Potential selective attrition.

Resumen

The study revealed bi-directional links between multimorbidity and depressive symptoms among Chinese adults. Functional dependence was a significant pathway in the cycle of multimorbidity and depressive symptoms, especially for cardiometabolic diseases. These insights suggest that interventions aimed at preventing functional dependence may be beneficial in mitigating the risk of coexisting mental and physical disorders.
