We examined variations in IPAQ validity in the Hong Kong Chinese population by six factors sex age job status educational level body mass index BMI and visceral fat level VFL . Methods A total of 1 270 adults aged SD years male completed the Chinese version of IPAQ IPAQ-C and wore an accelerometer ActiGraph for four days afterwards. The IPAQ-C and the ActiGraph were compared in terms of estimated Metabolic Equivalent Task minutes per week MET-min wk minutes spent in activity of moderate or vigorous intensity MVPA and agreement in the classification of physical activity. Results The overall Spearman correlation p of between the IPAQ-C and ActiGraph was low range in subgroups and was the highest among high VFL participants . Difference between selfreported and ActiGraph-derived MET-min wk overall 2966 140 was the smallest among participants with tertiary education 1804 208 . When physical activity was categorized into over or under 150 min wk overall agreement between self-report and accelerometer was subgroup range agreement was the highest among those who were employed full-time in physically demanding jobs . Conclusions Sex age job status educational level and obesity were found to influence the .
