All subjects were assessed QoL-Alzheimer's Disease (QoL-AD), Cumulative Illness Rating Scale, exercise habit, Mini-Mental State Examination, social activities, The Medical Outcomes Study-Social Support Survey. The data were analyzed with SPSS WIN V. 21.0 program.
RESULTS

The variables of professional, residence status, physical health, exercise, cognitive function, social activity participation and social support explained 29.3% of variance in QoL of community-dwelling elderly. Among these factors, the significant predictors of QoL were social support (β=0.322, p<0.001), cognitive function (β=0.152, p=0.021), and religion activity (β=0.152, p=0.025).
CONCLUSION
