Validation of the historical adulthood physical activity questionnaire (HAPAQ) against objective measurements of physical activity.

ABSTRACT:

Background

Lifetime physical activity energy expenditure (PAEE) is an important determinant of risk for many chronic diseases but remains challenging to measure. Previously reported historical physical activity (PA) questionnaires appear to be reliable, but their validity is less well established.
