Use of Personal Fitness Device in Adult (> 21 Years Old) Patients With Cystic Fibrosis

Approximately half of the variation in the presentation and disease status of patients with Cystic Fibrosis (CF) is secondary to non-genetic variables.\[1\] These include household income, compliance with therapy, second hand smoke exposure and possibly exercise (although exercise has less evidence to support its influence on disease status). Recently increased attention has been focused on the role of exercise and quality of life for patients with CF. This study will evaluate the role of exercise in relation to the patient's perception of their quality of life. The primary outcome will be the overall change in the patient's Cystic Fibrosis Questionnaire - Revised (CFQ-R) over a one year period during which the participants are encouraged to exercise and use a personal fitness device to track their exercise. This is a prospective single group non-blinded study. Participants will be asked to wear a personal fitness device for 11-13 months. The change in CFQ-R score is the primary outcome and other secondary outcomes will include; (1) exacerbations of cystic fibrosis (through use of antibiotics), (2) change in subject's FEV1, (3) inpatient admission rates, (4) change in BMI and (5) change in 6 minute walk test. The study will take place at the Adult CF Clinic on the University of Oklahoma Health Sciences Center campus.
