<p>Fysisk aktivitet kan redusere risikoen for flere kroniske sykdommer, og kan vurderes ved bruk av spørreskjema, eller måles objektivt. I en undersøkelse blant innvandrerkvinner fra Pakistan (n=86) har vi sammenlignet selvrapportert (International Physical Activity Questionnaire, IPAQ) og objektivt målt fysisk aktivitet (SenseWear Armband). For å sikre at kvinnene forsto hva det ble spurt om ble det benyttet prosjektmedarbeidere fra Pakistan og India som hjalp deltakerne til å svare på spørreskjemaet, som dessuten var oversatt til urdu, punjabi og engelsk. Vi fant ingen signifikant korrelasjon (Spearman) mellom de to målemetodene. Selvrapportert fysisk aktivitet var ikke signifikant korrelert med: alder, BMI, livvidde, HbA1c, fastende og ’2-timers glukose’, fastende insulin, C-peptid, sittende systolisk- og diastolisk blodtrykk, totalkolesterol, LDL-kolesterol og triglyserider. På den annen side fant vi en invers relasjon mellom objektivt målt fysisk aktivitet og nevnte variabler. Sammenhengene holdt seg ved aldersjustering (lineær regresjon). Deltakere med selvrapportert god fysisk form hadde lavere BMI, livvidde, serum insulin, triglyserider og diastolisk blodtrykk. Resultatene tyder på at selvrapportering av fysisk aktivitet ikke alltid gir god nok opplysning til å bedømme graden av fysisk aktivitet, slik det ble funnet ved å bruke spørreskjemaet IPAQ på dette utvalget av innvandrerkvinner. Objektiv måling av energiomsetning kan synes nødvendig for å få gode estimater på fysisk aktivitet og dens gunstige helseeffekter.</p><p> </p><p>Hjellset VT, Høstmark AT. Is self-reported physical activity suitable for studying health effects of light physical activity?    Nor J Epidemiol 2011; 20 (2): 135-142.</p><p><br />ENGLISH SUMMARY<br />Physical activity can reduce the risk of many chronic diseases, and may be estimated using questionnaires, or measured objectively. In a group of Pakistani immigrant women living in Oslo, Norway, we found no significant correlations between use of the self report International Physical Activity Questionnaire (IPAQ) and objectively measured physical activity as assessed using the accelerometer SenseWear Armband. To ensure that the women understood the questions, the questionnaire had been translated to urdu and punjabi, and interpreters from Pakistan and India helped them in filling in IPAQ. There was an inverse relationship between objectively measured physical activity and age, BMI, waist circumference, HbA1c, fasting and 2-h glucose value, fasting insulin and C-peptide, systolic- and diastolic blood pressure (sitting), total cholesterol, LDL cholesterol and triglycerides, persisting after adjustment for age. Participants reporting good physical fitness had lower BMI, waist circumference, serum insulin, triglycerides and diastolic blood<br />pressure as compared with those reporting bad fitness. The results suggest that self reporting may not be appropriate to evaluate the degree of physical activity, as shown in this group of immigrant women when using the International Physical Activity Questionnaire. An objective measure of energy expenditure seems to be necessary to obtain good estimates of physical activity and its beneficial health effects.</p>

Background: Studying the relationship between subjectively and objectively measured physical activity (PA) can provide viable information on youths’ behaviors. However, the restrictions due to COVID-19 pandemic, which reduced children’s possibilities to be active, may negatively affect it. The aim of this study was to assess the relationship between subjectively and objectively measured PA levels (light, moderate, vigorous, and moderate-to-vigorous) during COVID-19-based restrictions and after they were lifted, and to determine whether such relationships changed in these two periods. Methods: A total of 26 adolescents (58% girls; mean age = 12.4 ± 0.5) wore accelerometers during public restrictions and after they were removed. Participants also completed the International Physical Activity Questionnaire during the same periods. Results: High significant correlations were found at all levels of PA (r = 0.767–0.968) in both time periods, except for moderate PA during restrictions. Comparing the two periods, significantly higher correlations were found for moderate PA (p < 0.001) and moderate-to-vigorous PA (p = 0.003) after restrictions were lifted. Conclusions: In this highly active cohort of adolescents, results emphasize the potential threat of lockdown conditions for youths’ ability to accurately perceive their behaviors, with possible detrimental consequences on the short- and long-term health.

Abstract Background Physical inactivity is a global phenomenon in European welfare countries. Proper monitoring is essential to measure the physical activity level of the population. Methods In the Hungarian cohort of the European Physical Activity and Sport Monitoring System (EUPASMOS) project, our participants (N = 598) completed sociodemographic questions and the International Physical Activity Questionnaire – short form (IPAQ-SF) survey. The validity and reliability of the subjective measurement tool were examined, IPAQ-SF outcomes were contrasted against triaxial RM42 accelerometer wore for 7 consecutive days. Results The IPAQ-SF showed moderate internal consistency (Cronbach Alpha = 0.647). The concurrent validity of the IPAQ-SF to triaxial accelerometer indicated a significant weak-to-moderate correlation (R = 0.111–0.338, p = 0.042; p < 0.001). The test-retest reliability showed a significant correlation between two measurements (R = 0.788–0.981, p < 0.001). Conclusion The Hungarian version of the IPAQ-SF had excellent test-retest reliability, but low-to-fair concurrent validity for moderate and vigorous physical activity, walking and sitting time, as compared to the objective criterion measure among Hungarian adults.
