Topic: Risk, prevention and care in population studies
A total of 5 721 711 patients (3 302 579 female and 2 419 132 male) with incident dementia between 2014 and 2021 were included in the study. Female patients had lower crude 1-year mortality rates (21.8% vs 27.2% for male patients; P < .001) and lower rates of all-cause hospitalizations (46.9% vs 50.5%; P < .001). The unadjusted hazard of death associated with male sex was 1.30 (95% CI, 1.29-1.31; P < .001). After adjustment for age, race and ethnicity, Medicaid dual eligibility, medical comorbidity burden, and access to health care resources, the association was modestly attenuated (adjusted hazard ratio, 1.24; 95% CI, 1.23-1.26; P < .001). Similarly, the unadjusted hazard ratio of all-cause hospitalization associated with male sex was 1.13 (95% CI, 1.12-1.14; P < .001); the adjusted hazard ratio was 1.08 (95% CI, 1.08-1.09; P < .001). Male patients also had increased hazards of hospice stay, neuroimaging services, and hospitalization for neurodegenerative disease diagnosis or behavioral disturbance. Conclusions and Relevance: In this study, male patients with dementia had higher mortality rates and higher use of many health care services, especially hospital stays, than comparable female patients. Strategies to slow mortality and decrease health care use among male patients with dementia may be particularly impactful in limiting the burden of dementia. Given higher incidence of dementia among women, a focus on efforts to prevent dementia is necessary to achieve population-level health equity in dementia-attributable mortality by sex.

Key findings
- A total of 5 721 711 patients (3 302 579 female and 2 419 132 male) with incident dementia between 2014 and 2021 were included in the study.
- Female patients had lower crude 1-year mortality rates (21.8% vs 27.2% for male patients; P < .001) and lower rates of all-cause hospitalizations (46.9% vs 50.5%; P < .001).
- The unadjusted hazard of death associated with male sex was 1.30 (95% CI, 1.29-1.31; P < .001).
- After adjustment for age, race and ethnicity, Medicaid dual eligibility, medical comorbidity burden, and access to health care resources, the association was modestly attenuated (adjusted hazard ratio, 1.24; 95% CI, 1.23-1.26; P < .001).
- Similarly, the unadjusted hazard ratio of all-cause hospitalization associated with male sex was 1.13 (95% CI, 1.12-1.14; P < .001); the adjusted hazard ratio was 1.08 (95% CI, 1.08-1.09; P < .001).
Why it matters
In this cohort study of 5,721,711 patients with incident dementia, male patients had higher mortality rates and higher use of many health care services, especially hospital stays, than comparable female patients, with an adjusted hazard ratio of death of 1.24 for male sex. It suggests strategies to slow mortality and decrease health care use among male patients may be impactful, but does not test any treatment, cure or prevention for Alzheimer's disease.
