Bottom Line: The average PAEE from the 2 periods of objective measurements was compared to the self-reported data from the corresponding time periods in the questionnaire.Similarly, self-reported time spent in vigorous PA was significantly correlated with objective measurements of vigorous PA (Spearman r = 0.40; P < 0.001).HAPAQ demonstrates convergent validity for total PAEE and vigorous PA.

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.

Methods: We sought to design and validate an historical adulthood PA questionnaire (HAPAQ) against objective PA measurements from the same individuals. We recruited from a population-based cohort in Cambridgeshire, UK, (Medical Research Council Ely Study) in whom PA measurements, using individually calibrated heart rate monitoring, had been obtained in the past, once between 1994 and 1996 and once between 2000 and 2002. 100 individuals from this cohort attended for interview. Historical PA within the domains of home, work, transport, sport and exercise was recalled using the questionnaire by asking closed questions repeated for several discrete time periods from the age of 20 years old to their current age. The average PAEE from the 2 periods of objective measurements was compared to the self-reported data from the corresponding time periods in the questionnaire.

Results: Significant correlations were observed between HAPAQ-derived and objectively measured total PAEE for both time periods (Spearman r = 0.44; P < 0.001). Similarly, self-reported time spent in vigorous PA was significantly correlated with objective measurements of vigorous PA (Spearman r = 0.40; P < 0.001).

Conclusions: HAPAQ demonstrates convergent validity for total PAEE and vigorous PA. This instrument will be useful for ranking individuals according to their past PA in studies of chronic disease aetiology, where activity may be an important underlying factor contributing to disease pathogenesis.

Mentions: Participants were recruited from the MRC Ely Study [14,15], a population-based prospective cohort study of the aetiology of type 2 diabetes and other metabolic disorders. The current mean age of the cohort is 65 years. Objective measurements of PAEE were taken from 394 members of this cohort at two separate time points, once between 1994 and 1996 (period 1) and again between 2000 and 2002 (period 2) (Figure 1). Of these, in December 2007, 197 individuals were ineligible for this study as they had previously declined further research participation, were currently recruited to another study or had died. Invitations were sent to the remaining individuals, of which 108 agreed to participate (55%). 100 attended for interview between December 2007 and March 2008. Ethical approval for the study was granted by the Cambridge Local Research Ethics Committee and all participants provided written informed consent.
