Brief Summary

Physical activity seems to be a prognostic factor for quality of life and survival in patients with cystic fibrosis (CF). Whereas their exercise capacity has been assessed through medical examination, their daily physical activity has been little studied. Activity monitors have measured physical activity only in a few studies which considered mainly respiratory status and more recently bone mineral density and body composition. Determinants of physical activity in patients with CF remain largely unknown. The objective of this study is to measure daily physical activity with activity monitors in adult patients with CF and to investigate the determinants of physical activity, with a focus on extra-respiratory factors (nutritional status, diabetes, bone mineralization, anxiety and/or depression, cardiac impairment). Seventy adult patients with CF, regularly cared at the Cochin adult CF centre, will be recruited in a stable period during their annual review. During this assessment, laboratory tests will be carried out (especially parameters for nutritional status), as well as measurement of body composition and bone mineral density, respiratory function tests and a 6 minute walk test, and echocardiography. Patients will wear for 7 consecutive days a multi-sensor armband SenseWear on the arm, to assess the intensity of physical activity in metabolic equivalents (METS) and steps per day. Finally, patients will complete three self-administered questionnaires: Quality of Life (CFQ14 +), hospital anxiety depression scale and physical activity. After a descriptive analysis of the study cohort, we will study qualitative and quantitative criteria related to physical activity (assessed quantitatively by the number of steps/day or metabolic equivalents). Linear regression models will then be developed to assess the independent factors associated with physical activity, adjusting for different variables of interest related to patients demographic, behavioral, clinical (respiratory and non-respiratory ) and biological parameters. Conversely, the "predictive" independent aspect of physical activity will be studied according to respiratory function, nutritional status and quality of life.

Outcome Measures

Primary Outcomes (2)

  • Steps per day

    The armband indicates the mean number of steps per day over a 7-day period

    Day 7

  • Physical activity level

    The investigators determine the physical activity level by dividing total daily energy expenditure by whole-night sleeping energy expenditure

    Day 7
