Maintaining a consistent fitness routine from your mid-40s onward may lower your chances of experiencing dementia, as suggested by recent research.
Dementia is the leading cause of death in the UK, and it has been widely reported that 45 percent of cases might be avoided through lifestyle adjustments initiated earlier in life, such as incorporating regular physical exercise.
Nevertheless, the specific age at which physical activity offered the greatest protective effect remained unclear, prompting a group of researchers from Boston University to investigate further.
Under the leadership of Dr. Phillip H. Hwang from the Department of Epidemiology, the study analyzed data from 4,354 adults who were children of participants in the Framingham Heart Study.
They aimed to observe the extent of physical activity individuals engaged in during various life stages and whether this influenced their likelihood of developing dementia.
The participants—none of whom had dementia—were divided into three groups: 1,526 young adults with an average age of approximately 37; 1,943 middle-aged adults with an average age of about 54; and 885 older adults whose average age was roughly 71.
To evaluate the impact of physical activity on their likelihood of developing dementia, the researchers examined whether participants had acquired the condition during a specific follow-up period.
This era differed among the groups, with young adults being tracked for 37 years, middle-aged adults for 25, and older adults for 14 years.
Throughout the research, 567 individuals were diagnosed with dementia, of whom 369 were identified as having Alzheimer's Disease.
Alzheimer'sThe most prevalent type of dementia is disease andaffects982,000 individuals in the United Kingdom.
Alzheimer's Research UK's study identified 74,261 individualspassed away due to dementia in 2022, in contrast to 69,178 the previous year,making it the leading cause of death in the country.
By analyzing the data, researchers determined that there was no connection between an individual's level of activity during young adulthood and their likelihood of developing dementia in the future.
Nevertheless, engaging in physical activity during middle age and later years was linked to a reduced likelihood of dementia onset.
Physical activity was reported by participants using the Physical Activity Index (PAI), which is a combined score derived from the number of hours spent sleeping and engaging in sedentary, light, moderate, or intense activities.
Based on data from the PAI, participants were divided into five groups ranging from Q1 (least active) to Q5 (most active).
Individuals who were the most engaged (Q5) during midlife experienced approximately a 41 percent reduced likelihood of developing dementia in comparison to those who were the least active (Q1).
Individuals who were most engaged (Q5) in their later years experienced approximately a 45 percent reduced chance of developing dementia when compared to those who were the least active (Q1).
The results, featured in the medical journal JAMA, were particularly comparable for Alzheimer's disease, which was the most prevalent form of dementia in the research. This reflects reality, as Alzheimer's makes up 60 percent of all dementia cases.
Dr. Hwang stated, "We discovered that increased physical activity during middle age and later years was linked to comparable decreases in the risk of all-cause dementia and dementia caused by Alzheimer's disease."
These results could guide future initiatives aimed at postponing or avoiding dementia by focusing on timing strategies and public health campaigns throughout the key phases of adulthood.
Some constraints were present in this research, such as the fact that the majority of participants were white, meaning caution should be exercised when generalizing the results to individuals from different ethnic groups.
Additionally, the PAI measurements could have been incorrectly categorized or unreliable since the information was provided by individuals themselves.
For years, specialists have cautioned that prolonged periods of inactivity increase the likelihood of various health issues such as weight gain, type 2 diabetes, cancer, and potentially a shortened lifespan.
The NHS advises adults to engage in a minimum of 150 minutes of moderate-intensity physical activity each week—or 75 minutes of high-intensity exercise.
A sedentary way of life in the UK, where citizens spend their workdays seated at desks, then remain seated on trains or in cars while commuting home, only to sit in front of the television, is believed to result in thousands of deaths annually.
One 2019 projection estimated the yearly fatality rate at 70,000 people a yearwith the health problems resulting in costsNHS£700 million per year for treatment.
