Predictors of non-response in a UK-wide cohort study of children's accelerometer-determined physical activity using postal methods.

ABSTRACT: To investigate the biological, social, behavioural and environmental factors associated with non-consent, and non-return of reliable accelerometer data (≥2 days lasting ≥10 h/day), in a UK-wide postal study of children's activity. Nationally representative prospective cohort study. Children born across the UK, between 2000 and 2002. 13 681 7 to 8-year-old singleton children who were invited to wear an accelerometer on their right hip for 7 consecutive days. Consenting families were posted an Actigraph GT1M accelerometer and asked to return it by post. Study consent and reliable accelerometer data acquisition. Consent was obtained for 12 872 (94.5%) interviewed singletons, of whom 6497 (50.5%) returned reliable accelerometer data. Consent was less likely for children with a limiting illness
