A recent study identified disability status and physical activity levels as 2 prominent factors associated with the likelihood of being an excessive sitter in persons with multiple sclerosis (MS) and this will inform the design of future interventions for reducing sedentary behavior in this population. Data were obtained from 6,483 persons with MS who completed the semi-annual survey of the North American Research Committee on Multiple Sclerosis registry conducted in 2015. Sociodemographic, clinical, and behavioral data were collected using self-report questionnaires. Sitting time per day was determined using the International Physical Activity Questionnaire. Researchers conducted data analyses and defined those classified above the 75th percentile of sitting time as excessive sitters. They found:

• Participants who were moderately disabled, severely disabled but ambulatory, or severely disabled but non-ambulatory were respectively 1.57, 2.62, and 8.70 times more likely to be excessive sitters than those reporting mild disability.
• Persons with MS who were insufficiently active were 2.61 times more likely to be excessive sitters than persons who were sufficiently active.
