Gender differences in modifiable dementia risk factors in monolingual and bilingual Australian adults

Abstract

AbstractIssue AddressedGender and bilingualism are reported to influence the risk of dementia. This study examined the prevalence of self‐reported modifiable dementia risk factors by gender in two samples: one that speaks at least one language other than English (LoE) and one that speaks only English.MethodsA descriptive cross‐sectional study was conducted on a sample of Australian residents aged 50 years or over (n = 4339). Participant characteristics and dementia risk behaviours were inspected using descriptive statistics in data collected via online surveys between October 2020 and November 2021.ResultsIn both samples, men had a higher rate than women of being overweight and were classified more frequently as being at risk of dementia due to alcohol consumption, lower cognitive activity, and non‐adherence to the Mediterranean‐style diet. Men reported better management of their cardiometabolic health than women across both groups. Non‐significant trends showed men were more often smokers but more physically active than women in the LoE group, and less often smokers but less physically active than women in the English‐only group.ConclusionThis study found men and women reported similar patterns of dementia risk behaviours regardless of LoE or English‐only status.So What?Gender differences in risk behaviours prevail regardless of language‐speaking status. The results can be used to guide future research aiming to understand and reduce modifiable dementia risk in Australia and beyond.
