Note. MIDUS: N= 4898; HRS: N= 6220; NHATS: N= 6494

Ns differ for depressive symptoms, disease burden, physical inactivity, functional limitations, and cognition because data were missing. Education was reported on a scale ranging from 1 (no grade school) to 12 (doctoral level degree) in the MIDUS, on a scale from 1 (No schooling completed) to 9 (Master’s, professional or doctoral degree) in the NHATS, and in years in the HRS. See method section for differences in assessments and coding of each variables in each sample.
