花王ヘルス&ウェルネス研究所と、弘前大学大学院医学研究科の中路重之特任教授の研究グループは、弘前大学COIが実施する「弘前市いきいき健診」で得られた健康ビッグデータを活用して、内臓脂肪と認知機能および脳の構造の関係性について検討し、結果を発表した。
As a result of the study, people over 65 years old and more visceral fat have found that cognitive function has been significantly reduced and brain structural abnormalities have occurred.
This suggests that reducing visceral fat can also contribute to reducing dementia risk.
Brain Sciences
The results of the research were published as the opening paper in the international academic journal "Brain Sciences" on neuroscience.
There are mainly two types of obesity, subcutaneous fat type and visceral fat type, and generally is the index of abdominal circumference and BMI.It is known that the visceral fat type is obese with fat around the internal organs centered on the stomach, and is related to the risk of developing lifestyle -related diseases.
However, the method of accurately measuring visceral fat is generally a computer fault shooting (CT) test, and medical research has not progressed much due to its invasive and the complexity of measurement.
Dementia is one of the diseases that have been attracting attention in recent years, and it is being understood that prevention is important.
One of the preventive factors is that it has been found that obesity suppression is important, but it has been found that there is a limit to using abdominal circumference and BMI as an index.
Therefore, in the large -scale cohort study ( * 2) "Hirosaki City Ikiiiki Miken", which is conducted by Hirosaki University COI, using the "visceral fat meter ( * 1)" developed by Kao, it is recognized as visceral fat.He said he had examined the relationship between functions.
■ Methods and results
Of the 65 and 80 -year -olds who participated in the "Hirosaki City Ikiiki Medical Examination" conducted in 2016-2017, 2,364 people were analyzed, except for those who were diagnosed with dementia.
Measured visceral fat is measured using the above -mentioned orgus fat meter, and is classified as a group with high visceral fat (n = 1,143) and a small group (n = 1,221) based on the median value of the obtained visceral fat.
