Physical Activity Levels in Individuals with Cystic Fibrosis-Related Diabetes.

The literature on physical activity (PA) in adults with cystic fibrosis, particularly in those with cystic fibrosis-related diabetes (CFRD), is limited. PA may be an important part of blood glucose management in CFRD. The purpose of this study was to describe PA levels in adults with CFRD and determine their adherence to the Canadian Diabetes Association (CDA) aerobic exercise training guidelines. Adults with CFRD were recruited from a hospital-based CF clinic. PA was measured using the Seven-Day Physical Activity Recall (telephone interview), adherence to CFRD management with the Self-Care Inventory-Revised (questionnaire), and blood glucose control from glycated hemoglobin levels documented in participants' medical chart within 3 months. Eighteen adults (mean age 41 [SD 9] y) with diagnosed CFRD participated in the study. They varied in volume of PA (range 13,080-17,362 metabolic equivalent min/wk). Of the study participants, 12 (67%) met the CDA guidelines of 150 minutes of moderate to vigorous PA per week with no more than 2 consecutive days without exercise. No differences were found in clinical factors between those who met the aerobic exercise guidelines and those who did not. The majority of individuals with CFRD are meeting the recommended amount of aerobic PA. The factors influencing PA and blood glucose control in adults with CFRD require further investigation.
