e median sedentary time was 360 (240-480) minutes per day. Sedentary time per
transplant group is summarized in Table 2. To study the associated factors of sedentary
time, two multiple linear regressions were performed (Table 4.). variables explained 12% (adjusted R2) of the variance in sedenta
comorbidities, education, length of hospital stay, exercise self-e

after variable selection included: gender, type of transplantation (lung, heart),

cacy, employment status,
fear of negative e

e contribution and
importance of these associated factors is illustrated in Supplemental Figure 2. Signi

Figure 2. In uence of age on the level of physical activity. e gure demonstrates the uctuating association between the age of recipients and the level of physical activity. Younger recipients have lower levels of physical
activity (± 500 min./week less), the highest levels of physical activity are determined around the age of 60
after which the level of physical activity decreases with increasing age. Age is centered at the mean of the population (56.8 years). Black line: spline estimate; dotted line: 95% con dence intervals.
