What term describes the underrepresentation in clinical trials of racial/ethnic minorities, women, the elderly, and low-SES populations, leading to inequitable treatment efficacy?

• A. Cultural competence in healthcare
• B. Religious considerations for healthcare
• C. Disparities in medical research
• D. Self-awareness and humility

Answer: (C)

Underrepresentation of certain groups in clinical trials describes disparities in medical research. When racial and ethnic minorities, women, older adults, and people with low socioeconomic status are not adequately included, trial results may not reflect how these populations will respond to treatments. This limits the generalizability of findings and can lead to inequitable treatment efficacy because safety and effectiveness data come from a non-representative sample. The other options touch on related but different issues: cultural competence concerns how clinicians interact with diverse patients, religious considerations address beliefs that can affect care, and self-awareness and humility relate to recognizing biases in practice, but none capture the systemic problem of unequal participation in research that drives inequitable treatment outcomes.
