"The Lancet" sub-issue: A cohort study of centenarians in China shows that the prevalence of cognitive decline over the age of 80 has reached 76.6%!

As the elderly population has steadily increased, so has the prevalence of cognitive decline

While aging is the strongest factor associated with cognitive decline, other factors such as malnutrition may also be involved

This study conducted a household survey of all centenarians and older adults living in 16 cities and counties in Hainan Province from June 2014 to June 2016, according to the China Hainan Province Centenarian Cohort Study (CHCCS)

The overall prevalence of cognitive decline was 76.

Multivariate logistic regression analysis showed that participants with higher PNI and MNA-SF were less likely to have cognitive decline (Table 2, Table 3, Table 4)

PNI and mnas-sf identified all subjects without cognitive decline

The prevalence of cognitive decline in centenarians was significantly higher than that in the elderly ( 87.

The most important independent risk factor for cognitive decline is age, but other factors include demographic , genetic, and nutritional parameters .
