Bone density test may reveal dementia risk

The Lancet-Regional Health-Western Pacific published a study showing that the degree of calcification of the abdominal aorta may reveal the risk of Alzheimer's disease, and assessing the degree of calcification of the abdominal aorta can be achieved by a common bone density scan.

The study involved older women aged 70 years and older who were assessed for abdominal aortic calcification based on their lateral spine bone density test data and were classified as "low,"moderate" or "severe" based on the degree of calcification. "severe" groups. The results of more than a decade of health follow-up showed that the "moderate" and "severe" groups had twice the risk of hospitalization and death from dementia than the "low" group. The new study suggests that the degree of calcification in the abdominal aorta can also be used to reveal the risk of dementia. Determining the degree of abdominal aortic calcification is as simple as adding a lateral scan of the spine to a routine bone density test.

A study published in the Asia Pacific Journal of Cancer Prevention showed that high levels of physical activity were associated with a lower overall risk of rectal and colon cancer, and that sedentary behavior was associated with an increased risk of rectal cancer.

A total of 1516 pairs of participants were included in the study, which calculated their physical activity to assess the association between participants' physical activity, sedentary behavior and overall colorectal, colon and rectal cancer risk. The analysis found that participants with the highest activity levels had a 33% reduced risk of rectal cancer, a 23% reduced risk of colon cancer, and a 28% reduced risk of colorectal cancer compared to those with the lowest activity levels. Sedentary behavior was positively associated with the risk of rectal cancer, and participants with sedentary behavior had a 19% increased risk of rectal cancer compared with those without sedentary behavior; sedentary behavior was not significantly associated with the risk of colon cancer.
