The influence of PA on the anxiety and stress cluster showed Pearson's chi-square = 9.9, DF = 4, = 0.04239, critical value = 9.5. The influence of PA on the anxiety, depression and stress cluster showed Pearson's chi-square = 6.8; DF = 5; -value = 0.24; critical value = 11.1.

Conclusion: In the elderly, PA has a significant relationship with anxiety, stress and QOL. In addition, the high level of QOL of the elderly in the sample demonstrates the capacity for PA, educational level and spirituality for personal satisfaction.
