A new complete microsimulation, using data from 40 million people, examines the future of older Japanese people by 2043. It ensures that many people will live longer, and the entire years spent with dementia will to reduce. However, the model shows a varied impact on different segments of the population, because Japanese women who have not reached secondary school and are 75 years of age may be more likely to be unbalanced and unbalanced. Improved understanding of where such a health gap exists can help inform public health plans, reduce future economic costs and support those most in need.

Caring for older members of the community is a global concern. Japan is famous for its long-term residents, whose numbers continue to grow. By 2020, nearly 30% of Japan’s population will be 65 years of age or older, and this age group is not predicted to reach its peak until 2034. Care for people with age-related diseases, such as insanity and weakness, posing a challenge to individuals. and public health systems.

Microsimulation devices, which are computer models that can provide detailed analysis of individual data, are currently being used to advance public health in other countries, such as the UK and Professor Hideki Hashimoto of the United States and researchers at the University of Tokyo, with researchers. from Stanford University in the United States, wanted to create a new microsimulation model for Japan, which would take into account different conditions than previously thought.

“We have created a new Japanese microsimulation model that reaches 13 normal conditions (including heart disease, stroke, diabetes, anxiety and depression), and trauma and dementia, ”Hashimoto said. aged 60 and up from 2016 to 2043. ”

According to Hashimoto, the perception of aging in Japan is usually based on the “average” status of the elderly so do not consider population differences. “I believe that aging is a long-term health problem,” he said. “Our forecast points to a widening of the health gap among the elderly. It shows that women who are not in secondary school age 75 or older are more likely to be infected.”

It can be used to find out where such a health gap exists for more information public policy, not only about health but also about other aspects of life. “The case of Japan may suggest that improving the quality of education, and public health, may be key to creating a healthier and healthier society,” Hashimoto said.

True, this study, published in Lancet Public Health, offers the hope of a future where many will live longer and healthier lives. “People may believe that the increase in the number of people with dementia cannot be avoided, given the age. However, in this study we found that in Japan, despite the large number of people who old age, the number of people affected by the disease. rabies It is expected to decline in the next 20 years, “said Hashimoto,” population growth does not necessarily mean increasing the burden of social care, but it does bring a variety of problems that need to be studied. depth and attention to science-related policies, to closure. ailment.”
