Background: The Physical Activity Questionnaire for Children and Adolescents (PAQ-C/-A) provides general estimates of physical activity levels. Following recent expert recommendations for using the PAQ for population surveillance, the aim of this paper was twofold: first, to describe normative PAQ data for English youth; and second, to determine a criterion-referenced PAQ-score cut-off point. Methods: Participants (n = 7226, 53% boys, 10-15 years) completed an anglicized version of the PAQ. Peak oxygen uptake (VO2peak) was predicted from PACER lap count according to latest FITNESSGRAM standards and categorized into at-risk and no-risk for metabolic syndrome. ROC curves were drawn for each age-sex group to identify PAQ scores, which categorized youth into sufficiently active versus low-active groups, using cardiorespiratory fitness as the criterion-referenced standard. Results: PAQ scores were higher in boys than in girls and declined with age. Mean PAQ score was a significant, albeit relatively weak (area under the curve < 0.7) discriminator between at-risk and no-risk. PAQ scores of >= 2.9 for boys and >= 2.7 for girls were identified as cut-off points, although it may be more appropriate to use lower, age-specific PAQ scores for girls of 13, 14 and 15 years (2.6, 2.4, 2.3, respectively). Conclusion: The normative and criterion-referenced PAQ values may be used to standardize and categorize PAQ scores in future youth population studies.
