2. The efficacy of PEP4PA to improve physical functioning, blood pressure (BP), depressive symptoms and quality of life. Hypothesis: Participants in PEP4PA will significantly increase their physical functioning (measured objectively by the short physical performance battery and 400m timed walk), decrease their systolic BP (mmHg) and reporting of depressive symptoms, and improve their quality of life scores (measured at baseline, 6 & 12 months) to a greater extent than older adults in control centers.
