MCI = Mild Cognitive Impairment, WP = Walking Program, PAP = Placebo Activity Program, FA/B12/B6= Folic Acid, Vitamin B12, Vitamin B6 supplementation, D-QoL = Dementia Quality of Life, SF12-MCS = Short Form 12 Mental Component Summary, SF12-PCS = Short Form 12 Physical Component Summary
a Higher rating indicates better QoL
* P < 0.05 (difference between FA/B12/B6 and placebo)
