INTRODUCTION: Few studies have explored dementia risk according to sex and gender including for transgender and non-binary adults. This study evaluated dementia risk factors and risk scores among cisgender, transgender, and non-binary adults.
METHODS: Observational data were drawn from the 2019 Behavioral Risk Factor Surveillance System. A matched-cohort approach was used to develop sex (male, female) and gender identity cohorts (cisgender men, cisgender women, transgender men, transgender women, and non-binary adults) for comparison. Dementia risk scores were calculated using established mid-life and late-life risk score algorithms.
RESULTS: Males had higher overall mid-life dementia risk, and lower late-life Alzheimer's disease risk compared to females. Transgender men, transgender women, and non-binary adults had higher overall late-life risk compared to both cisgender men and women.
DISCUSSION: Future research is needed to build the evidence base for specific risk factors that may be contributing to higher overall risk among understudied and underserved gender groups.
HIGHLIGHTS: Using data from the 2019 Behavioral Risk Factor Surveillance System, this matched-cohort study found that those assigned female at birth had lower overall mid-life dementia risk and higher overall late-life Alzheimer's disease (AD) risk compared to those assigned male at birth. Transgender men, transgender women, and non-binary adults all showed higher overall late-life AD risk compared to cisgender men and cisgender women. Between-group differences were found in the incidence of specific risk and protective factors for dementia and AD.
