“…Associations between self-reported and objectively measured PA were assessed using Pearson correlation. Multiple linear regression analyses were performed to assess the association between self-reported total amount of PA (MET-min day 21 ) and the total amount of objectively measured PA (total counts min 21 day…”

“…Data from these studies suggest a relatively high degree of validity for quantifying the intensity of PA 7 -11 . Additionally, average intensity (average counts min 21 ) measured over several days has also been shown to be significantly associated with EE estimates measured by the doubly labelled water method under free-living conditions in children, adolescents, young athletes and adults 12 -15 . In the present study, the monitor was initialised as described by the manufacturer and a 1-min epoch was used.…”

“…Selfreported time spent sitting was significantly and positively correlated with time spent in sedentary behaviour by accelerometry (i.e. , 100 counts min Next we examined whether gender, age, education and BMI affected the association between the total amount of objectively measured PA (average counts min 21 ) and self-reported PA (MET-min day 21 ). Total amount of self-reported PA was the only variable which contributed significantly to the explained variation in objectively measured PA (adjusted R 2 ¼ 0.14; P , 0.0001).…”

Objective: To examine the validity of the short, last 7-day, self-administered form of the International Physical Activity Questionnaire (IPAQ). Design: All subjects wore an accelerometer for seven consecutive days and completed the IPAQ questionnaire on the eighth day. Criterion validity was assessed by linear regression analysis and by modified Bland -Altman analysis. Specificity and sensitivity were calculated for classifying respondents according to the physical activity guidelines of the American College of Sports Medicine/Centers for Disease Control and Prevention. Setting: Workplaces in Uppsala, Sweden. Subjects: One hundred and eighty-five (87 males) participants, aged 20 to 69 years. Results: Total self-reported physical activity (PA) (MET-min day 21 ) was significantly correlated with average intensity of activity (counts min 21 ) from accelerometry (r ¼ 0.34, P , 0.001). Gender, age, education and body mass index did not affect this relationship. Further, subcomponents of self-reported PA (time spent sitting, time in PA, time in moderate and vigorous activity (MVPA)) were significantly correlated with objectively measured PA (P , 0.05). Self-reported time in PA was significantly different from time measured by accelerometry (mean difference: 2 25.9 min day 21 ; 95% limits of agreement: 2 172 to 120 min day 21 ; P , 0.001). IPAQ identified 77% (specificity) of those who met the current PA guidelines of accumulating more than 30 min day 21 in MVPA as determined by accelerometry, whereas only 45% (sensitivity) of those not meeting the guidelines were classified correctly. Conclusions: Our results indicate that the short, last 7-days version of the IPAQ has acceptable criterion validity for use in Swedish adults. However, the IPAQ instrument significantly overestimated self-reported time spent in PA. The specificity to correctly classify people achieving current PA guidelines was acceptable, whereas the sensitivity was low.

“…Falkner et al studied the reliability of recall of physical activity in the last 30 years and found acceptable levels of recall (48). Validity studies of physical activity questionnaires using accelerometers and/or physical activity logs have shown acceptable validity (46,49). In a review focused on the limitations of physical activity questionnaires, Shephard concluded that although detailed interpretation and attempts to estimate precise dose are inadvisable, the use of data to monitor change in population activity and provide categorical estimates is of value (44).…”

Objective. To develop and demonstrate the feasibility of a method for estimating lifetime hip and knee cumulative joint force using survey data on physical activity, and to construct and describe lifetime trajectories of energy expenditure and hip and knee joint force. Methods. Exposure data on lifetime physical activity, including type (occupational, household, and recreation) and dose (frequency, intensity, and duration), were collected from a Canada-wide population study of adults ages >45 years. Subjects were ranked in 2 ways: in terms of physical activity-related energy expenditure and in terms of a cumulative peak force index (CPFI) for the hip and knee, which is a measure of lifetime exposure and is a time/joint force product involving years of force and subject bodyweight. A relative joint loading index was calculated as the ratio of joint force (CPFI score) to energy expenditure. Results. A total of 4,269 subjects completed the baseline measurements. Lifetime energy expenditure and hip and knee CPFI scores were higher for occupational and household activity than sport. The mean lifetime energy expenditure from total physical activity in the study sample was 119.1 metabolic equivalent-hours/week. Women had slightly higher total lifetime energy expenditure and CPFI scores than men. The relative joint loading index was highest for male household and sport activity and lowest for female occupational activity. Conclusion. Lifetime cumulative hip/knee joint force trajectories were successfully constructed from survey data and followed expected trends. Comparing energy expenditure with joint force revealed variation by age, sex, and activity type, indicating these measures may help distinguish the numerous benefits of physical activity from possible risks.

Validity and reproducibility of a physical activity questionnaire in women

Abstract: These data indicate that this physical activity questionnaire is reproducible and provides a useful measure of current activity, particularly vigorous activity, over a 1-yr period.
