Study Notes
Biological Parameters and Normalcy
- "Normal" encompasses a range of biological values, rather than a single fixed point.
- Sources of variation in biological parameters include:
- Genetics: Genetic differences can significantly influence biological norms.
- Age: Heart rates vary by age; for example, a 3-year-old's heart rate is typically tachycardic compared to an adult's.
- Gender (Sex):
- Hormonal differences affect parameters; testosterone leads to a higher red blood cell (RBC) count.
- Situational Factors:
- Living conditions affect RBC counts, e.g., sea level vs. high altitude.
- Time: Hormone levels fluctuate; testosterone peaks in the morning, while female hormone levels vary with the ovulation cycle.
- Laboratory Conditions: Each lab has specific reference values that can differ based on testing methods.
Race and Medicine
- Historically, "race" has been misused in medicine to classify variation in biological parameters.
- The definition of race lacks biological foundation, as race is a socially constructed category.
- Broad racial categories (e.g., African American, Hispanic) do not correlate with actual genetic differences.
- Belief that race is tied to ancestry-related genes is misleading, as these genes account for only 0.1% of genetic differences among individuals.
- Race is often inaccurately utilized as a substitute for true genetic ancestry.
Implications of Race in Medicine
- The application of race in medicine has a detrimental historical context, often justifying injustices like enslavement.
- Continued misuse of racial categories detracts from addressing genuine instances of racial injustice in healthcare.
- The categorization of patients by race leads to flawed diagnostics and treatment methodologies.
- Misrepresentations reinforce stereotypes and the notion of significant biological differences among racial groups.
- Such practices result in:
- Implicit bias within medical training and practice.
- Development of harmful healthcare standards that can adversely affect patient outcomes.
