Summary
This summary is machine-generated.Foreign-born individuals showed slightly lower willingness to join Alzheimer's disease (AD) trials compared to US-born participants. Understanding sociocultural factors is key for inclusive AD clinical trial recruitment.
Area Of Science
- Neuroscience
- Clinical Trials
- Sociology
Background
- Racial and ethnic minorities are underrepresented in Alzheimer's disease (AD) preclinical trials.
- Sociocultural factors like assimilation, education, and socioeconomic status may influence trial participation differently between foreign-born and US-born individuals.
- Limited research exists on how nativity impacts decisions to enroll in AD biomarker trials.
Purpose Of The Study
- To explore differences in willingness to learn AD biomarker status and enroll in preclinical AD trials between foreign-born and US-born participants.
- To investigate the influence of sociocultural factors on trial participation decisions.
Main Methods
- Recruited a diverse sample of cognitively unimpaired older adults via community outreach.
- Collected mixed-methods data, including cognitive interviews in English, Spanish, and Korean.
- Utilized a conjoint experiment where participants rated willingness to join 16 trial scenarios (7-point Likert scale).
- Collected sociodemographic data, including country of origin and duration in the US.
- Planned to use linear regression and proportional odds models to analyze the association between nativity and willingness, controlling for covariates.
Main Results
- The study included 263 participants, with 132 foreign-born and 131 US-born.
- Foreign-born participants were more likely to be NH Asian and Hispanic/Latino compared to US-born participants.
- US-born participants reported a mean willingness score of 63.47, while foreign-born participants reported a mean score of 60.3.
Conclusions
- Sociocultural factors influencing trial participation decisions are often overlooked in recruitment strategies.
- Preliminary data suggest potential differences in willingness to participate based on nativity.
- Findings can inform the development of more inclusive and efficient recruitment strategies for AD clinical trials and biomarker disclosure.

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
• Adult screening for blood pressure, cholesterol, and diabetes
• Cancer screenings such as colonoscopies and...
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
