Narrative objectives1

In Ogano Study1 in 2018, no one was deficient in vitamin B1. However, it was revealed that about half of the people experienced "insomnia". Therefore, Ogano Study 2 was developed with the aim of further developing Ogano Study 1 and mainly studying the relationship between the causes of "insomnia" from the physical and mental aspects.
There have been many studies on the causes of insomnia, but it can be roughly divided into physical and mental factors.
Therefore, in Ogano Study 2, in addition to vitamin B1, vitamin B12, folic acid, vitamin D, zinc, as well as VB12 and the possibility of anemia related to folic acid deficiency, the current state is clarified.
Next, as a research approach to the mental aspect, we will focus on depression, which has been reported to be associated with insomnia. Depression has been pointed out to continue to "depressive state", "adaptation disorder", and "Major Depressive Disorder", and insomnia is a typical symptom of depression, so attention should be paid in a preventive sense. In addition, bereavement has been reported as the largest risk factor for the onset of depression in the elderly, and confirmation of bereavement experience is important as a background of daily life.
Furthermore, we focus on "Fail" as a state related to both physical and mental aspects. Flail is defined as a state of increased vulnerability to health problems due to various functional changes and decreased reserve ability with age (Japan Geriatrics Society), and the average age of Ogano Study 1 participants was 65 years or older Even with that in mind, an assessment of flail is necessary.
Ogano Study 2 is planned based on the results obtained in Ogano Study1, and by addressing the potential risks by examining the current status of the physical and mental state of the study subjects, damage due to serious deficiency The purpose is to prevent health while preventing health.

Other related information

The following describes the measurement items in Ogano Study 2, the scientific basis for the evaluation items, and the factors that examine the relevance.
Vitamin B1 (VB1) is an essential coenzyme for sugar metabolism, but it cannot be synthesized in vivo, so it depends on ingestion from outside the body. However, the amount of VB1 accumulated in the body is not sufficient for about 18 days, and deficiency is likely to occur if food intake continues to decline.
Vitamin B12 (VB12) is essential for normal red blood cell formation, nerve function, and DNA synthesis. Folic acid is also important as a coenzyme for substances involved in DNA synthesis together with VB12. When folic acid is deficient, giant erythroblasts appear. In addition to anemia, VB12 deficiency can cause potentially serious and irreversible damage to the brain and nerves. It is becoming clear that vitamin D is involved not only in bone metabolism but also in various biological phenomena. Zinc deficiency causes taste disorders, loss of appetite, stomatitis, and intractable pressure ulcers.
The effect of insomnia on health is significant. Insomnia is a risk factor for depression, and the risk is 2--9. Depression has been pointed out as a continuum from depression to adaptation disorder and depression, and it has been reported that the experience of bereavement may trigger the onset of depression in elderly people. Insomnia is a typical symptom of depression, so be careful.
This is a cross-sectional epidemiological study that targets VB1 and VB12 deficiency, folic acid, VD, zinc deficiency, anemia, insomnia and depression rates in the general population that have not been previously revealed, and the elderly. This is a study to clarify the current situation by evaluating the flail.
