BACKGROUND: The COVID-19 pandemic disrupted traditional health care delivery models, exacerbating disparities between those with and without ready access to digital technology. This digital divide poses a structural barrier to accessing equitable healthy aging resources and dementia care. Latino and Hispanic individuals, who constitute nearly half of Los Angeles County's population and face a projected tripling of Alzheimer disease and related dementia (ADRD) prevalence by 2040, are particularly impacted. OBJECTIVE: This paper aims to examine the barriers and facilitators affecting access to digital health education and resources for Alzheimer disease (AD) prevention and care management during the COVID-19 pandemic. This study focuses on the digital barriers possibly hindering Spanish-speaking Latino and Hispanic individuals in Los Angeles County from using online services offering critical AD prevention and care resources amid the COVID-19 pandemic. METHODS: We developed a conceptual model based on users' digital access or web literacy and language as barriers and facilitators impacting access to digital AD prevention and care resources. Between January 2022 and February 2022, we identified 15 websites of local organizations providing digital AD prevention services and resources in Los Angeles County during the pandemic. We applied our digital divide model to qualitatively evaluate the 15 websites. A post hoc analysis was conducted to reevaluate the 15 websites in 2025, and interrater reliability was evaluated using a Cohen κ analysis. RESULTS: Out of the 15 websites, 5 featured web navigation accessibility tools (4/15 in 2025), 4 provided content available in Spanish (6/15 in 2025), and 2 included resources for family dialogue about AD care and management (3/15 in 2025). One website showed cultural and linguistic responsiveness in its content (2/15 in 2025). Cohen κ analysis revealed substantial agreement for digital acceptability factors including Spanish language (κ=0.71), resources available in Spanish (κ=0.71), and family dialogue resources (κ=0.74). Agreement for web accessibility tools was moderate at (κ=0.53). We uncovered other unforeseen structural barriers to digital access, including email subscription requirements, English language-centered online forms, and the limited availability of Spanish-speaking staff. CONCLUSIONS: Our study highlights structural barriers hindering access to digital AD prevention and care resources tailored to the needs and values of Latino and Hispanic communities living in Los Angeles County. The findings emphasize the need to bridge the digital gap by incorporating user-friendly features and culturally and linguistically responsive elements in website design and implementation. This approach will move our field toward equitable access to digital ADRD prevention and care resources by mitigating structural barriers that sustain ADRD disparities in Latino and Hispanic communities.
