Habitual physical activity and cardiometabolic risk factors in adults with cerebral palsy.
Adults with cerebral palsy move far less and sit far more, and the low activity tracks directly with higher heart-risk numbers.
01Research in Context
What this study did
The team asked adults with cerebral palsy to wear a small hip accelerometer for one week.
They compared the daily minutes of moderate-to-vigorous activity and sitting time with a same-age group without CP.
Blood pressure, waist size, and cholesterol were also measured to look for heart-risk clues.
What they found
Adults with CP moved less and sat far more than the comparison group.
Lower activity went hand-in-hand with bigger waists, higher blood pressure, and worse cholesterol.
The results show that low movement is tied to real health danger, not just fitness scores.
How this fits with other research
Griffith et al. (2012) saw the same low-activity pattern in kids with CP, hinting the problem starts early and stays.
Lee et al. (2024) used the same accelerometer method in autistic adults and also found people over-rate their own activity, backing the need for objective tools.
Zwinkels et al. (2017) tracked CP youth for ten years and saw BMI rise even when skill tests improved, showing weight risk can grow even when clinic scores look stable.
Together the four papers draw a straight line: low MVPA begins in childhood, continues into adulthood, and quietly drives cardiometabolic harm.
Why it matters
If you serve teens or adults with CP, do not trust self-reports of "active enough." Clip on an accelerometer for a week to get the real picture.
Use the data to write precise goals: add two short brisk walks or stand-and-stretch bouts each day.
Small, steady increases in movement can chip away at sitting time and may trim waist size and blood pressure without new meds.

03Original abstract
Adults with cerebral palsy (CP) are known to participate in reduced levels of total physical activity. There is no information available however, regarding levels of moderate-to-vigorous physical activity (MVPA) in this population. Reduced participation in MVPA is associated with several cardiometabolic risk factors. The purpose of this study was firstly to compare levels of sedentary, light, MVPA and total activity in adults with CP to adults without CP. Secondly, the objective was to investigate the association between physical activity components, sedentary behavior and cardiometabolic risk factors in adults with CP. Adults with CP (n=41) age 18-62 yr (mean ± SD=36.5 ± 12.5 yr), classified in Gross Motor Function Classification System level I (n=13), II (n=18) and III (n=10) participated in this study. Physical activity was measured by accelerometry in adults with CP and in age- and sex-matched adults without CP over 7 days. Anthropometric indicators of obesity, blood pressure and several biomarkers of cardiometabolic disease were also measured in adults with CP. Adults with CP spent less time in light, moderate, vigorous and total activity, and more time in sedentary activity than adults without CP (p<0.01 for all). Moderate physical activity was associated with waist-height ratio when adjusted for age and sex (β=-0.314, p<0.05). When further adjustment was made for total activity, moderate activity was associated with waist-height ratio (β=-0.538, p<0.05), waist circumference (β=-0.518, p<0.05), systolic blood pressure (β=-0.592, p<0.05) and diastolic blood pressure (β=-0.636, p<0.05). Sedentary activity was not associated with any risk factor. The findings provide evidence that relatively young adults with CP participate in reduced levels of MVPA and spend increased time in sedentary behavior, potentially increasing their risk of developing cardiometabolic disease.
