Abstract: | The purpose of this study was to validate a physical activity (PA) questionnaire, Questionnaire d'Activité Physique Saint-Etienne
(QAPSE), in an homogenous population of elderly subjects and to estimate its potential for application in routine PA assessments
in that age group. A group of 65 (31 men and 34 women) community dwelling, healthy people aged 65–84 years volunteered to
participate in a validation substudy comparing maximal oxygen uptake (
) and anthropometric data.
correlated positively with mean habitual daily energy expenditure (MHDEE) (r=0.56,P<0.0001), greater than 3MET (metabolic equivalent) daily energy expenditure (DEE) activity (r=0.371,P=0.002), leisure activity (r=0.368,P=0.003), sports activity (r=0.461,P<0.0001), basic daily activity (r=0.325,P=0.008) and moving DEE activity (r=0.273,P=0.028) in both sexes, with MHDEE (r=0.366,P=0.043) and moving DEE activity (r=0.388,P=0.031) in the men and with MHDEE (r=0.624;P<0.001), greater than 3MET DEE activity (r=0.513,P=0.002), leisure activity (r=0.388,P=0.024) and sports activity (r=0.683,P<0.001) in the women. The MHDEE was positively correlated with body mass (r=0.464) and with fat free mass (r=0.639) and negatively correlated with percentage body fat (r=−0.501). In a reproducibility substudy (n=44) a paired Student'st-test, based on mean differences between the two administrations of the questionnaire did not reach statistical significance
for any of the QAPSE activity scores studied. Test-retest correlation coefficients ranged from 0.648 for moving score to 0.967
for MHDEE with correlation coefficientP values being less than 0.001 for all of the QAPSE activity scores. We concluded that QAPSE demonstrated excellent repeatability
and good validity in relation to physical fitness and anthropometric data in the population of these healthy elderly volunteers. |
