Reliability and validity of the international physical activity questionnaire in the Nord-Trøndelag health study (HUNT) population of men

<p>Abstract</p> <p>Background</p> <p>There is no standardized method for the assessment of physical activity (PA). Therefore it is important to investigate the validity and comparability of different measures. The International Physical Activity Questionnaire (IPAQ) has been developed as an instrument for cross-national assessment of PA and has been validated in 12 countries. These instruments have acceptable measurement properties for monitoring population levels of PA among 18–65 year-old adults in diverse settings. However, there are some concerns that IPAQ may over-report PA.</p> <p>The purpose of this study is to evaluate the reliability and validity of IPAQ, short version, last 7-days in the Nord-Trøndelag Health Study (HUNT) population of men.</p> <p>Methods</p> <p>The questionnaire was administered twice to a random sample of 108 men aged 20–39 and validity by comparing results with VO_2maxand ActiReg, an instrument that measures PA and energy expenditure (EE). ActiReg discriminates between the body positions: stand, sit, bend forward and lie and also registers if there is motion or not in each of them or both.</p> <p>Results</p> <p>Our results for reliability of the IPAQ short version were good for vigorous and fair for moderate activities. Intraclass correlations ranged from a low of 0.30 for moderate activity hours, to a high of 0.80 for sitting hours. Concerning validity, our results suggest that total IPAQ vigorous PA was a moderately good measure of vigorous activity, having moderately strong, significant correlations with VO_2max, r = 0.41 (p ≤ 0.01), but correlated not with metabolic equivalent (METs) values of 6 or more measured with ActiReg. Only total IPAQ walking was fair correlated with METs 1–3 and METs 3–6, respectively r = -0.27 and 0.26 (p ≤ 0.05). The index for IPAQ sitting hours per week was moderate correlated with METs values of 1–3 and negatively correlated with METs values of 3–6. Classification of PA in three levels (low, moderate and high) correlated also most strongly with VO_2max(0.31 p ≤ 0.01) and METs 3–6 and METs 1–3 from ActiReg (r = 0.32 and -0.31, p ≤ 0.01). Classification of BMI in three levels (normal, overweight and obese) correlated most strongly negative with VO_2max(-0.42 p ≤ 0.01) and MJ from ActiReg (r = 0.31 p ≤ 0.01).</p> <p>Conclusion</p> <p>Our results indicate that IPAQ short version for men has acceptable reliability and criterion validity for vigorous activity and sitting. Walking has moderate reliability. Only the IPAQ for walking had a fair correlation with METs 6+. The questions about moderate activity had fair reproducibility and correlated poorly with most comparison measures.</p

Effekt av brukermedvirkning i institusjoner for barn og unge. Systematisk litteratursøk med sortering

Seksjon for velferdstjenester ved Kunnskapssenteret fikk i september 2015 i oppdrag av Barne‐, ungdoms‐ og familiedirektoratet å identifisere forskning om effekt av bru‐ kermedvirkning i institusjoner for barn og unge. Dette oppdraget skulle være et syste‐ matisk litteratursøk med sortering. Vi har derfor gjort systematiske litteratursøk, lest sammendrag i tråd med definerte inklusjonskriterier og sortert inkluderte studier etter type. Vi har ikke lest artiklene i sin helhet, vurdert studienes kvalitet eller sammenstilt resultatene, slik vi ville gjort det i en systematisk oversikt

Reliability and validity of two frequently used self-administered physical activity questionnaires in adolescents

Abstract Background To create and find accurate and reliable instruments for the measurement of physical activity has been a challenge in epidemiological studies. We investigated the reliability and validity of two different physical activity questionnaires in 71 adolescents aged 13–18 years; the WHO, Health Behaviour in Schoolchildren (HBSC) questionnaire, and the International Physical Activity Questionnaire (IPAQ, short version). Methods The questionnaires were administered twice (8–12 days apart) to measure reliability. Validity was assessed by comparing answers from the questionnaires with a cardiorespiratory fitness test (VO2peak) and seven days activity monitoring with the ActiReg, an instrument measuring physical activity level (PAL) and total energy expenditure (TEE). Results Intraclass correlation coefficients for reliability for the WHO HBSC questionnaire were 0.71 for frequency and 0.73 for duration. For the frequency question, there was a significant difference between genders; 0.87 for girls and 0.59 for boys (p 2peak were fair, ranging between 0.29 – 0.39. The WHO HBSC questionnaire measured against VO2peak for girls were acceptable, ranging between 0.30 – 0.55. Both questionnaires, except the walking question in IPAQ, showed a low correlation with PAL and TEE, ranging between 0.01 and 0.29. Conclusion These data indicate that the WHO HBSC questionnaire had substantial reliability and were acceptable instrument for measuring cardiorespiratory fitness, especially among girls. None of the questionnaires however seemed to be a valid instrument for measuring physical activity compared to TEE and PAL in adolescents.</p

Adolescents with wheeze have increased risk of additional health problems. The Young-HUNT study, Norway

OBJECTIVE: To explore the hypothesis of an association between current wheeze and other health problems in adolescence and to investigate any sex differences. METHODS: N=8817 adolescents aged 13-19 years completed a self-administered questionnaire including questions on health and lifestyle in Norway (1995-1997). RESULTS: All subjective health problems were significantly more prevalent in current wheezers compared to non-wheezers (frequent headache: girls 18% vs. 9%, boys 8% vs. 3%; frequent neck and shoulder pain: girls 10% vs. 5%, boys 6% vs. 2%; frequent joint and muscle pain: girls 6% vs. 2%, boys 6% vs. 2%; and frequent abdominal pain: girls 10% vs. 3%, boys 3% vs.1%). In both sexes, adjusted for covariates, current wheezers had statistically significant increased risk of reporting frequent headache (girls OR=2.0, boys OR=2.9), frequent neck and shoulder pain (girls OR=1.9, boys OR=3.3), frequent joint and muscle pain (girls OR=2.7, boys OR=3.5) and frequent abdominal pain (girls OR=2.7, boys OR=2.0). CONCLUSIONS: Current adolescent wheezers reported more additional health problems compared to non-wheezers. Even if girls reported more symptoms in general, the associations were stronger in boys. The findings are important for the clinical approach to teenage wheezers and should increase doctors' awareness of coexistence of other health complaints in these patients
