What this trial studies

This observational study aims to assess dietary intake and behaviors among adults with Sickle Cell Disease (SCD) to understand how these factors influence their overall health. Participants will undergo a review of their medical records, physical exams, and dietary assessments through surveys and laboratory results. The study will explore associations between dietary habits, clinical severity, psychosocial health, and social determinants of health. By utilizing a cross-sectional design, the research seeks to gather comprehensive data on the nutritional status of individuals with various clinical phenotypes of SCD.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a documented clinical diagnosis of Sickle Cell Disease.

Not a fit: Patients who are under 18 years of age or have Sickle Cell trait genotype may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how dietary interventions may improve health outcomes for patients with Sickle Cell Disease.

How similar studies have performed: While there is ongoing research into the dietary impacts on Sickle Cell Disease, this specific approach focusing on dietary behaviors and social determinants is relatively novel.
