A comparison of subjective and objective measures of physical activity from the Newcastle 85+ study.

ABSTRACT:

Background

Little is known about physical activity (PA) in the very old, the fastest growing age group in the population. We aimed to examine the convergent validity of subjective and objective measures of PA in adults aged over 85 years.
