2.4.1 ActiGraph GT3X+accelerometer
2.4.2 Outcomes measured
2.4.3 Physical Activity Questionnaire - Children (PAQ-C)
2.5 Comparison between ActiGraph & PAQ-C
2.6 Analysis

3 Findings
3.1 Objective Measurement of physical activity
3.1.1 Overall Activity Levels - weekday and weekend activity by gender
3.1.2 Time spent Sedentary and in MVPA - weekday and weekend activity by gender 17 Sedentary time - Area deprivation and Gender Area deprivation and Gender
3.1.3 Meeting the PA guidelines using 'Threshold' approach Guideline adherence by area deprivation - Threshold approach
3.1.4 Meeting the PA guidelines using 'Averaging' approach Guideline adherence by area deprivation - 'Averaging' approach
3.2 Self-reported physical activity
3.2.1 Validation of PAQ-C Accelerometer and PAQ-C - MVPA Accelerometer and PAQ-C - counts per minute (CPM) PAQ-C scores between those who do and do not meet the CMO guidelines - 'Averaging' method
3.2.2 PAQ-C scores - Overall, Gender, and by SIMD
