Note.
P < .05,
P < .01,
P < .001 for the association between the quality of life variable and current physical activity status. Each adjusted analysis controls for all of the demographic and medical variables shown in Tables 1 and 2. P values less than .05 are denoted by italics.
Sedentary = engage in no light, moderate, or strenuous activity; Low Activity = engage in some light, moderate, or strenuous activity, but below guideline recommended levels; Meet Guidelines = engage in at least 150 minutes per week of at least moderate intensity activity or engage in at least 60 minutes per week of vigorous intensity activity.
For each SF-36 subscale (physical functioning, role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, mental health, role limitations due to emotional problems), scores represent norm-based T-scores (general population mean = 50, general population standard deviation = 10), and a higher score represents better quality of life. For the dyspnea measure, a higher score represents lower dyspnea (possible range, 0–12). For the measures of fatigue (possible range, 0–10), anxiety symptoms (possible range, 0–21), and depression symptoms (possible range, 0–21), a higher score represents a greater prevalence of symptoms.
