Middle-aged women who are overweight are closer to Alzheimer's disease

　　male Being too underweight has greater risks

　　In contrast, men who are too underweight in middle age are more likely to suffer from this degenerative brain disorder. disease The risk is relatively high. This is the latest research result reported in the American Journal of Epidemiology.

　　In addition, studies have also pointed out that changes in body weight have different effects on the development of Alzheimer's disease in men and women.

　　The Baltimore Longitudinal Aging Study included 2,322 men and women who were followed for 23 years. The results of the study found that 187 of them were suffering from Alzheimer's disease.

　　obese female , those aged 30, 40 or 45, with a body mass index of 30 or above, and a large waist circumference, have a six times higher risk of developing Alzheimer's disease than the general population.

　　Thin men, in their 30s, 40s, or 45s, with a body mass index of 18. People with a weight of 5 and below have a five times higher risk of developing Alzheimer's disease than those with a normal weight.

　　On the other hand, if women lose weight between the ages of 30 and 45, their risk of developing Alzheimer's disease in the future will be twice as high as that of ordinary people.

　　If a man's weight increases significantly between the ages of 30 and 50, the risk of developing Alzheimer's disease in the future is 3.7 times higher than that of a man whose weight remains stable.
