Data unavailable for 45-54 at baseline of all studies;
cell sizes for 95+ too small to be reliable.
Note: Percentage (%) refers to number of individuals at baseline in that group with that condition.
Medical conditions are obtained by self-report; Vision loss is defined by presenting distance visual acuity greater than 0.3 logMAR in the better eye; Mild hearing loss is defined by averaged pure tone thresholds greater than 25 dB in the better ear; Moderate to severe hearing loss is defined by averaged pure tone thresholds greater than 40 dB in the better ear.
