Do daily-living limits track depression in older Chinese adults?
Among 9,789 CHARLS adults ≥60, ~43.5% had high-risk CES-D scores; BADL and IADL limitations roughly tripled adjusted depression odds.

- N

What they did
Used CHARLS wave 4 to relate 12-item ADL (BADL/IADL) limitations to CES-D-10 depressive symptoms with generalized linear mixed-effect models.
What they found
High-risk depression prevalence 43.5%; BADL limitation 19.02%; IADL limitation 25.29%. Limited BADL (OR-adjusted 2.71) and IADL (2.68) associated with higher depression risk vs no limitation.
The limits
What it doesn't show
Cross-sectional CHARLS data cannot establish whether disability causes depression or the reverse; residual confounding remains.
