Beyond donor eligibility: nutritional and lifestyle heterogeneity and implications for long-term donor health preservation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Blood donor eligibility is essential for donation safety, but it may not fully capture nutritional, metabolic, and lifestyle-related vulnerabilities that can affect donor health over time. As transfusion systems increasingly rely on regular donors, identifying modifiable factors that may support long-term donor health and retention is becoming increasingly relevant. This study aimed to characterize nutritional and lifestyle heterogeneity, peri-donation dietary behaviors, and donation-related outcomes in adult blood donors. Methods: This cross-sectional survey used a structured online questionnaire assessing anthropometric characteristics, lifestyle factors, habitual dietary intake, nutrition-related awareness, peri-donation dietary behaviors, self-reported history of iron deficiency, and post-donation symptoms. Dietary profiles were identified using principal component analysis followed by k-means clustering. Multivariable logistic regression models were used to explore factors associated with iron deficiency history and post-donation symptoms. Results: The study included 698 adult blood donors. Overweight and obesity affected nearly half of the cohort and were more frequent among men and older donors, whereas women more frequently reported iron deficiency history and post-donation symptoms. Three dietary profiles were identified: Western/ultra-processed, Mediterranean-like, and mixed beverage-oriented. Younger donors were more frequently represented in less favorable dietary and lifestyle profiles, whereas older donors showed more favorable dietary habits despite a higher prevalence of overweight/obesity. In multivariable analyses, female sex was independently associated with iron deficiency history (OR 4.62, 95% CI 3.20-6.68; Discussion: These findings suggest that adult blood donors represent a nutritionally and metabolically heterogeneous population despite donation eligibility. These findings support the potential relevance of structured nutritional counseling, lifestyle-oriented prevention, and recovery-focused recommendations within donor care pathways, although their impact on long-term donor health, continued eligibility, and donor retention should be evaluated in future prospective and interventional studies.
