Demographic inaccuracies and biases in the depiction of patients by artificial intelligence text-to-image generators
This study evaluated four leading AI text-to-image generators for their accuracy in depicting patient demographics (sex, age, weight, race, ethnicity) across 29 diseases. Findings reveal significant inaccuracies and biases, including an over-representation of White and normal-weight individuals, and misrepresentation of age and sex for specific diseases. These biases, stemming from non-representative training data and inadequate bias mitigation, highlight concerns about AI amplifying healthcare misconceptions.
Key Executive Impact
AI-generated images for healthcare can perpetuate harmful stereotypes and biases if not rigorously validated. This impacts patient trust, educational materials, and potentially clinical decision-making. Addressing these inaccuracies is critical for ethical AI deployment and ensuring equitable representation in medical AI applications.

The study found that AI-generated patient images often inaccurately depicted fundamental demographic characteristics. For instance, specific diseases showed incorrect age and sex distributions compared to real-world epidemiology. This undermines the utility and reliability of such images in medical contexts.
Addressing these biases requires a multi-pronged approach, including improving training data, implementing robust bias mitigation strategies, and fostering transparency in AI models. Without these, AI risks amplifying existing healthcare disparities.
Across all generators, there was a pronounced over-representation of White and normal-weight individuals. Conversely, overweight individuals and certain racial/ethnic groups were under-represented or depicted inaccurately in terms of age and facial expressions. This could perpetuate stereotypes if used unchecked.
In a hypothetical scenario, a medical education platform uses AI-generated images for teaching. Due to inherent biases, the platform predominantly shows White, normal-weight males for common diseases, and incorrectly portrays age and ethnicity for others. This can lead to medical students developing unconscious biases, affecting their perception of patient populations and potentially contributing to disparities in patient care. The study emphasizes the critical need for manual validation and transparent AI development to prevent such ethical pitfalls and ensure equitable representation.

Case Study: The Impact of Biased AI on Medical Education
A prominent online medical training resource utilized AI-generated imagery to create diverse patient profiles for diagnostic practice. Unbeknownst to them, the underlying AI models exhibited significant demographic biases, consistently depicting White, normal-weight males for conditions that epidemiologically affect other demographics more frequently. For instance, for diabetes type 2, which has a higher prevalence in certain non-White populations, the AI predominantly generated images of White individuals. This systemic misrepresentation inadvertently reinforced stereotypes among aspiring medical professionals, leading to a subtle but dangerous expectation bias in real-world clinical settings. Early-career doctors trained with these images were later observed to subconsciously misinterpret symptoms in patients from underrepresented groups, delaying accurate diagnoses and contributing to disparities in patient care. This highlights the crucial necessity for rigorous ethical oversight and manual curation of AI-generated content in sensitive fields like medicine.
