Findings from Nagoya University Provides New Data about Dementia (Leisure-time physical activity and risk of disability incidence: A 12-year prospective cohort study among young elderly of the same age at baseline)

By a News Reporter-Staff News Editor at China Weekly News -- Investigators publish new report on Neurodegenerative Diseases and Conditions - Dementia. According to news reporting originating in Nagoya, Japan, by VerticalNews journalists, research stated, "To clarify the role of physical activity in preventing disability in Japan, we investigated the association between amount of leisure-time physical activity and incidence of disability among the young elderly. In the New Integrated Suburban Seniority Investigation (NISSIN) project conducted from 1996 to 2013, we followed 2888 community-dwelling adults aged 64-65 years with no history of cerebrovascular disease for a median follow-up of 11.6 years."

Financial support for this research came from Nisshin Medical and Dental Associations.

The news reporters obtained a quote from the research from Nagoya University, "Disabilities were defined as follows based on the classifications of the Japanese long-term care insurance system: 1) support or care levels (support levels 1-2 or care levels 1-5); 2) care levels 2-5; 3) support or care levels with dementia; and 4) care levels 2-5 or death. In addition, we also assessed 5) all-cause mortality. After controlling for sociodemographic, lifestyle, and medical factors, male participants reporting an activity level of 18.1 metabolic equivalent (MET)-hours/week (the median among those with activities) or more had 52% less risk of being classified as support or care levels with dementia compared with the no activity group (hazard ratio 0.48; 95% confidence interval, 0.25-0.94). No significant association was found among women between amount of leisure-time physical activity and incidence of disability. We identified an inverse doseeresponse relationship between the amount of leisure-time physical activity and the risk of disability with dementia in men."

According to the news reporters, the research concluded: "Therefore, a higher level of physical activity should be recommended to young elderly men to prevent disability with dementia."
