Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 5, Issue 2
Abstract
Objectives: The goal of this study was to summarize epidemiological studies of dementia in China, Japan, America and Europe, and to make comparison of the prevalence rate and risk factors in these countries to analyze differences among them. Methods: Electron¬ic databases including PUBMED, EMBASE, WEB OF SCIENCE, CNKI, CBM, VIP and WANGFANG are searched for relevant articles about epidemiological study of dementia. Results: From 2000 to 2005, the prevalence of dementia was 5.15% in China,15% in Japan and 4%-8% in Europe. Risk factors of dementia are different among countries as age, gender, education and other factors. Conclusion: Gender and education are two of most important risk factors of dementia. Dementia is one of the main disorders associated with disability, institutionalization, and mortality among elderly individuals [1]. This disease is caused by damage to neurons in the brain. This, in turn, can lead to changes in one’s memory, behavior, and ability to think clearly. China encompasses a very large geographical area and a widely diversified population comprising many different ethnic, cultural, and socioeconomic aspects [2]. With the accelerated aging trend of the Chinese population (the latest statistics indicate that the population aged 65 and above has reached 10.47% [3], we need to better characterize the overall epidemiologic profile of dementia in China, and we also wished to make comparison with developed countries like Japan, America and Europe by analyzing the differences between them in this regard. Comparisons of Prevalence of Dementia among Countries One study used Meta-analysis to investigate the prevalence of dementia in the elderly aged ≥65 years in China from 2000 to 2015 and it turned out to be 5.15% [4]. The overall prevalence of dementia in western developed countries has been reported to be approximately 4% to 8% among people aged 65 years and older [5,6], and this figure turned out to be 15% in Japan [7]. Globally, the prevalence of dementia has been shown to vary across countries likely due in part to differences in demographics, education and genetics.
