Prevalence of Cognitive Impairment Among an Eastern Chinese Population At High Cardiovascular Disease Risk in 2020

Cardiovascular factors increased the risk of dementia. We investigated the associations between such factors, and tested that if a population with a high level of cardiovascular risk would have a higher prevalence of cognitive impairment. Participants (n=3082; ages=55+; 46.4% female) at high risk of CVD in Zhejiang province Registry for PEACE Million Persons Project, completed 3+ neuropsychological evaluations. Age-, gender- standardized prevalence rates were calculated based on the sixth population census for population of China. Adjusted logistic regression models were used to ascertain the risk factors of dementia. Trial registration number: NCT02536456. There was a high prevalence of cognitive Impairment, coupled with the fact that stroke, diabetes, hypertension and depression were significant risk factors. Cognitive impairment are highly prevalent among elderly at high risk of CVD in Zhejiang province. More population-based strategies, including preventing CVD and reducing cardiovascular risk factors would be an effective way to reduce the dementia burden.
