Are Self-report Measures Able to Define Individuals as Physically Active or Inactive?

摘要: Purpose: Assess the agreement between commonly used self-report methods compared with objectively measured physical activity (PA) in defining prevalence of individuals compliant PA recommendations. Methods: Time spent moderate and vigorous (MVPA) was at two time points 1713 healthy from 9 European countries using individually-calibrated combined heart-rate movement sensing. Participants also completed Recent Physical Activity Questionnaire (RPAQ), short form International (IPAQ) Prospective Investigation into Cancer Nutrition (EPIC-PAQ). Individuals were categorized as active (e.g. reporting >=150 min MVPA per week) or inactive, based on information derived different measures. Sensitivity specificity analyses Kappa statistics performed to evaluate three PAQs ability correctly categorize inactive. Results: Prevalence estimates being sufficiently varied significantly (p for all <0.001) measures (IPAQ 84.2 % [95% CI 82.5 85.9], RPAQ 87.6% 85.9 89.1], EPIC-PAQ 39.9% 37.5 42.1] objective measure 48.5% 41.6 50.9]. All showed low sensitivity 20.0 %, 18.7% 69.8%) classify inactive people self-reported ([latin kra] =0.07 0.02 0.12], 0.12 0.06 0.18] 0.19 0.13 0.24] IPAQ, RPAQ, EPIC-PAQ, respectively). Conclusion: The modest suggests that population levels should be interpreted cautiously. Implementation large-scale cohort studies surveillance systems is recommended.
