AI Article Synopsis
- Adults with multiple sclerosis (MS) experience sleep problems at a rate four times higher than the general population.
- This study focused on how sedentary behavior and different levels of physical activity relate to perceived sleep quality in adults with MS.
- Results showed a significant link between moderate-to-vigorous physical activity (MVPA) and better sleep quality, suggesting that increased physical activity could improve sleep outcomes for those with MS, but they generally don't engage in enough physical activity.
Article Abstract
Background: There is a fourfold higher prevalence of sleep problems in multiple sclerosis (MS) than the general population.
Objective: This study examined cross-sectional associations among device-measured sedentary and physical activity behavior with perceived sleep quality in adults with MS.
Methods: Adults with MS (N = 290) completed the Pittsburgh Sleep Quality Index (PSQI) and wore an accelerometer for seven days providing a measure of time spent in sedentary behavior, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) using MS-specific cut-points. We conducted multiple linear regression analysis to identify the independent contributions of variables for explaining PSQI scores.
Results: The overall model accounted for 2% of the variance in global PSQI scores, and MVPA was significantly and independently associated with global PSQI scores (β = ─0.123; p = 0.045; partial r = ─0.118) when accounting for average wear time, sedentary behavior, and time spent in LPA. There were no other significant associations with PSQI global score.
Conclusions: Our results suggest that time spent in MVPA may be associated with better sleep quality in adults with MS, but adults with MS do not spend sufficient time in physical activity. Researchers should evaluate these relationships in longitudinal study designs and behavior change interventions, as physical activity may provide a unique opportunity to improve sleep quality outcomes.

Almost universally, people living in rural and remote places die younger, poorer, and sicker than urban-dwelling citizens of the same country. Despite clear need, health services are commonly less available, and more costly and challenging to access, for rural and remote people. Rural geography is commonly cited as a reason for these disparities, that is, rural people are said to live in places too distant, too underpopulated, and too difficult to access.

Background: Research has shown that engaging in a range of healthy lifestyles or behavioral factors can help reduce the risk of developing dementia. Improved knowledge of modifiable risk factors for dementia may help engage people to reduce their risk, with beneficial impacts on individual and public health. Moreover, many guidelines emphasize the importance of providing education and web-based resources for dementia prevention.

Background: Insomnia is a prevalent sleep disorder affecting millions worldwide, with significant impacts on daily functioning and quality of life. While traditionally assessed through subjective measures such as the Insomnia Severity Index (ISI), the advent of wearable technology has enabled continuous, objective sleep monitoring in natural environments. However, the relationship between subjective insomnia severity and objective sleep parameters remains unclear.
