PMID 40165361WHAT IT FOUND
Device-measured physical activity, not sedentary time, was linked to better quality of life in adults with multiple sclerosis.
Moderate-to-vigorous activity correlated with both physical and psychological well-being, while light activity correlated only with physical well-being.
Key findings
01Moderate-to-vigorous physical activity was associated with better physical and psychological health-related quality of life.
02Light physical activity was associated with better physical health-related quality of life, but not psychological quality of life.
03Sedentary behavior was not associated with health-related quality of life once physical activity levels were taken into account.

What it does not show
The study design was cross-sectional, so it cannot prove that increasing activity causes better quality of life; people with better quality of life may simply move more. The sample was primarily older, Caucasian women with relapsing-remitting MS, which may not represent the broader MS population. The accelerometer did not capture water-based activities like swimming. The study did not distinguish between different types of sedentary behavior, such as watching television versus reading, which may have different impacts on well-being.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not conclude that reducing sedentary behavior is unimportant for health. The study found it was not linked to quality of life once physical activity was considered, but other research suggests sedentary time is linked to hypertension and mobility disability.
