New Study Suggests Sedentary Behavior May Increase Risk of Dementia
According to a recent study published in the JAMA medical journal, older adults who spend a significant amount of time sitting may have a higher risk of developing dementia. The study examined data from nearly 50,000 adults in the UK, all over the age of 60, who did not have dementia at the beginning of the research.
Participants in the study wore a wrist accelerometer to track their sedentary behavior, and follow-up analysis was conducted for an average of 6.72 years. Shockingly, out of the subjects, 414 were diagnosed with all-cause dementia during the study period.
The study found a significant correlation between the amount of time spent in sedentary behavior and the incidence of dementia. However, it is important to note that the study cannot determine whether this association is causal. More research is needed to understand the exact relationship between sedentary behavior and the risk of dementia.
The World Health Organization (WHO) recognizes several risk factors for dementia, including high blood pressure, diabetes, obesity, smoking, physical inactivity, and depression. Dr. Andrew E. Budson, a neurology professor, explains that people living in “blue zones,” regions where individuals tend to live longer, have lower rates of dementia due to their active lifestyles throughout the day.
In light of these findings, the study suggests that reducing the total time spent sedentary can help lower the risk of developing dementia, especially as one gets older. Experts recommend aiming for at least 7 hours of movement throughout the day to promote optimal brain health.
Overall, more research and public awareness are needed to emphasize the importance of reducing sedentary behavior in order to prevent dementia. By understanding and implementing strategies to combat prolonged sitting, individuals can take proactive steps towards maintaining their cognitive health as they age.
