This systematic review explored the awareness of the general public on the influence of modifiable cardiovascular risk factors on dementia. Despite the identified association between CVRFs and dementia, overall knowledge on this relationship is low among the public. Higher education, better economic status, and prior contact with dementia patients positively influence dementia risk knowledge.
Objectives This systematic review examined whether the general public are aware of the influence of modifiable cardiovascular risk factors (CVRFs) on dementia. Methods Following PRISMA guidelines, five electronic databases (PubMed, Medline, CINAHL, ProQuest, and Scopus) were searched for studies published from2009-2019, using the key terms knowledge, modifiable cardiovascular risk factors, and dementia. Standardized critical appraisal instruments were used to evaluate the quality of the studies. Results Of the 1,533 articles that were screened, 26 were included in this review. Modifiable CVRFs of dementia included behavioral factors (physical inactivity, poor dietary practices, high alcohol consumption, and heavy smoking) and medical conditions (hypertension, diabetes mellitus, hypercholesterolemia, and obesity). Although the association between CVRFs and dementia was identified (pooled prevalence is 24-50%), overall knowledge about this relationship in the general public was low. Sociodemographic variables, such as higher education, better economic status, and prior contact with a person with dementia, positively influenced dementia risk knowledge. Ethnic minorities showed good awareness of dementia risk from cardiovascular-related conditions. Conclusion Despite dementia is considered as a public health priority by World Health Organization, knowledge of the modifiable CVRFs and dementia is low in the general population. Public health policymakers should develop appropriate educational programs and interventions to equip the communities and vulnerable groups with this understanding so that they can be prepared to reduce dementia risk.
