Sample demographics by cognitive status group.

	NIC (n=197)	SA-MCI (n=126)	MA-MCI (n=85)
Age	75.44 (7.28)	76.71 (8.68)	75.68 (7.23)
Gender (% women)	64.5%	59.5%	51.8%

SR Health	1.92 (0.70)	1.80 (0.80)	1.89 (0.62)
SR Health-P	1.63 (0.69)	1.49 (0.70)	1.59 (0.62)

NIC = not impaired cognitively; SA-MCI = single assessment mild cognitive impairment reflecting cross-sectional classification or unstable classification across measurement occasions; MA-MCI = multiple assessment mild cognitive impairment reflecting stable classification observed across consecutive measurement occasions; SR Health = self-reported health relative to a perfect state on a 5-point scale that ranged from 0 (very good) to 4 (poor); SR Health-P = self-reported health relative to peers on a 5-point scale that ranged from 0 (very good) to 4 (poor). Values in parentheses are SDs.
