Validation in London of a physical activity questionnaire for use in a study of postmenopausal osteopaenia.
Study objective-To determine the validity of a self administered physical activity questionnaire to be used as part of a screening device for postmenopausal osteopaenia (with additional questions on medical history and calcium intake).
Design-A questionnaire was posted to 86 perimenopausal women to enquire about weekly hours spent in non-sedentary activity at work, in the household, and during leisure hours.
Subjects who returned the questionnaire were visited at home and asked to complete a four day activity diary and subsequently to undertake a submaximal estimate of VO2 MAX, carried out using a treadmill ergometer.
They were interviewed to clarify questionnaire and diary entries.
Questionnaire validity was assessed in comparison with the diary estimates of hours of activity and with VO2 MAX.
Participants-A total of 86 perimenopausal women aged 43-54 years were randomly selected from a GP list in Hammersmith, London.
Thirty five women (41%) returned the questionnaire.
They were visited at home, given the diary to complete, and invited to attend the physiology laboratory for VO2 MAX measurements.
Twenty six of the 35 (74%) completed the study and were included in the final analysis.
Main results-Women spent an average of 51 hours per week in non-sedentary activities.
Questionnaire and diary yielded similar results (51.05 versus 51.30 h/wk), and there was a good correlation between diary and questionnaire estimates of total weekly hours ofnon-sedentary activity (...)
