Several groups are often underrepresented in epidemiological studies:
- Racial and Ethnic Minorities: African Americans, Hispanics, Asians, and Native Americans are frequently underrepresented. - Women: Despite comprising half the population, women are often underrepresented, especially in clinical trials. - Elderly: Older adults have specific health needs that are not fully captured if they are underrepresented. - Low-Income Populations: People from socioeconomically disadvantaged backgrounds are less likely to be included in research.
