Background: The reduction in mobility due to hip diseases in children is likely to affect their physical activity (PA) levels. Physical inactivity negatively influences quality of life and health. Our aim was to objectively measure PA in children with hip disease, and correlate it with the PROMIS Mobility Score (lower limbs). Patients and Methods: 28 children (12 boys and 16 girls) with hip disease aged 8 to 17 years (mean 12±3 years) were studied between December 2018 and July 2019. Children completed the PROMIS Paediatric Item Bank v. 2.0 –Mobility Short Form 8a (lower limbs) and wore a hip worn accelerometer (ActiGraph) for 7 consecutive days. Sedentary time (ST), light PA, moderate to vigorous PA (MVPA) and vigorous PA were calculated from accelerometers data. Lower limbs mobility from the PROMIS questionnaire was classified as normal; mild; and moderate functions, based on the PROMIS cut scores on the physical function metric. A one-way ANCOVA was used to assess differences among mobility (normal; mild; moderate) and measured PA and relationships between these variables were assessed using bivariate Pearson Correlations. Results: Children classified as normally functioning on the PROMIS had less ST (p=0.002); higher MVPA (p=0.002) and VPA (p=0.004) compared to those classified as mild or moderate function. A moderate correlation was evident between the overall PROMIS score and daily LPA (r=0.46, n=28, p=0.01), moderate-to-vigorous PA (r=0.67, n=28, p=0.01) and vigorous PA (VPA) (r=0.54, n=28, p=0.01). No correlation was evident between the average daily ST and overall PROMIS score (r= -0.28, n=28, p=0.15) Conclusion: PROMIS lower limbs mobility tool is correlated to the PA level of children with hip disease and may provide a general overview of PA
