We examined the relationship between the amount of physical activity and
level of fatigue in adults with cystic fibrosis (CF). Method: Participants were
recruited from the Toronto Adult Cystic Fibrosis Centre at St. Michael's
Hospital. Participants completed the Habitual Activity Estimation Scale, the
Multidimensional Fatigue Inventory, and the Depression subscale of the Hospital
Anxiety and Depression Scale, in that order. Descriptive statistics and linear
and multiple regressions were computed.
Results: Over a 6-month period, 51
individuals were approached, and 22 (10 men, 12 women) participated in this
study. The participants' median age was 33, and forced expiratory volume in 1
second (FEV1) was 64% predicted. When holding both FEV1 and depression constant,
a significant negative correlation was found between total active hours per
weekday and general fatigue (beta=-0.735, p=0.03); there was a negative trend
between total active hours per weekday and physical fatigue (beta=-0.579,
p=0.09). Conclusions: This study is the first to demonstrate that among adults
with CF, a higher level of physical activity is associated with a lower level of
general and physical fatigue when controlling for lung function and level of
depression. Physical activity may be used as a means of mitigating the levels of
general and physical fatigue in people with CF.
