| Research Abstract |
With aging, calcium absorbed from the bone can be easily deposited in the arteries, causing arteriosclerosis. Therefore, we investigated strokes and myocardial infarctions among elderly people who participated in the osteoporosis screening examination. There were a total of 338 participants from the Akita prefecture, and 891 people from Tokyo. As a result, the odds ratio (OR) (and 95% confidence interval) of bone mass (low-to-high value) for new strokes was 1.22 (0.97-1.49) in men, and 1.18 (0.29-2.05) in women. Furthermore, the OR for new ischemic disease was 1.44 (0.63-2.26) in men, and 1.15 (-0.26-2.56) in women. Therefore, there seems to be a greater risk of stroke in men with low bone mass.
