Who could benefit from this research
✓Could help
Adults aged 21 and older who identify as Chinese, Korean, or Indian American and are willing to discuss and report their supplement use.
✕Less likely to help
Individuals not taking vitamin D or calcium supplements or not part of the specified Asian American groups may receive little direct benefit.
What this research studies
This project builds on MOSAAIC-NY to collect detailed, multilingual information about vitamin D and calcium supplement types, doses, and product characteristics from Asian American adults. Researchers will enroll 180 participants (60 from each group: Chinese, Korean, Indian) and develop standardized exposure measures and a screener that can be used across MOSAAIC sites. The effort aims to make future biomarker studies and long-term research more accurate by improving how supplement use is captured in diverse populations. Outcomes will include feasible data collection protocols and reusable tools tailored to community needs. The work is designed to inform how supplements relate to skeletal and cardiovascular health in these populations.
Why it matters
Potential benefit: Better understanding of how supplements are used could lead to more accurate guidance and safer, more effective vitamin D and calcium use for Asian American communities.
How similar studies have gone: Prior work has shown that standardized, population-specific supplement data collection improves measurement quality and research reliability.
