You should be able to:
Critically assess social and theoretical assumptions underpinning the concepts of `race' and ethnicity.
Explore the meaning of institutionalised racism in relation to health care.
Explore the theory and practice of ethnic monitoring within the Health Service

What is a species?
Were there several human species on Earth at any point?
How many human species are there on the earth today?

The group a person belongs to, or is perceived to belong to because of- physical features reflecting ancestry
Increasingly concept emphasises a common social, religious and political heritage
The concept is largely discredited in Europe, where it is displaced by ethnicity

The group a person belongs to, or is perceived to belong to, because of- culture, language, diet, religion, Ancestry and physical textures
Ethnicity subsumes race

3 main approaches i.e.
self-assessment
assessment by another using data assessment by another by observation.
However you do it, you need to create a classification-difficult
UK has taken the task seriously only in the last 20 years or so

Absolute risk approach: examine patterns within each group (primary).
Then compare with other ethnic groups-the relative risk approach (secondary).
The interpretation will be different. Maximise value by doing both. Absolute risk is your risk of developing a disease over a time-period. We all
have absolute risks of developing various diseases such as heart disease, cancer, stroke, etc. The same absolute risk can be expressed in different ways. For example, say you have a 1 in 10 risk of developing a certain disease in your life. This can also be said a 10% risk, or a 0.1 risk - depending if you use percentages or decimals.
Relative risk is used to compare the risk in two different groups of people. For example, the groups could be 'smokers' and 'non-smokers'. All sorts of groups are compared to others in medical research to see if belonging to that group increases or decreases your risk of developing certain diseases. For example, research has shown that smokers have a higher risk of developing certain diseases compared to (relative to) non-smokers.

“.. the superficial subcutaneous adipose tissue compartment is larger in whites than in South Asians. … South Asians exhaust the storage capacity of their superficial subcutaneous adipose tissue compartment before whites do and .. develop the metabolic complications of upper body obesity at lower absolute masses of adipose tissue than white people.” Sniderman et al (IJE February 2007)

Question: Are ethnic inequalities inequities i.e. injustices?
04/18/23 24
Healthcare inequality (also called health disparities in some countries) refers to the disparities in the access to adequate healthcare between different gender, race and socioeconomic groups.
Definition of inequity is when an individual considers that he/she is treated unfairly if he/she perceives the ratio of his/her inputs to his/her outcomes to be inequivalent to those around him/her.
04/18/23 25
Consider whether the following are inequities: The lower prevalence of smoking in Chinese
women compared to White women The higher rate of colo-rectal cancer in White
people compared to S. Asians The lower life expectancy of African
Americans compared to White Americans
What do you think? One deep problem is racism?.

“The genetic differences between the snail populations of two Pyrenean valleys are much greater than those between Australian aboriginals and ourselves. If you were a snail it would make good biological sense to be a racist: but you have to accept that humans are tediously uniform animals.”
Dr Steve Jones, The Independent.
The 1991 Reith lectures. 04/18/23 27
“Genetic explanations are … likely where differences … persist … in migrants who have been settled outside the home country for several generations and where .. differences are .. found in all countries where the migrant group has settled e.g. Scots (Mac) have higher incidence of Multiple Sclerosis … genetic factors are likely to underlie the high rates of coronary heart disease and non-insulin-dependent diabetes … in people of South Asian .. descent settled overseas.”

In an increasingly diverse society, which serves to enrich our lives and experiences, doctors must learn to value ethnic diversity to deliver effective health care. In doing so, they will bring mutual benefits for their patients and themselves.J Kai et al. Medical Education 1999 p622

International migration and exchange are creating multi-ethnic global societies.
The concept of ethnicity can improve public health, health care, and clinical care, and advance science
The greatest goal is that people should be long-lived, free of disease and disability, brimming with energy, creative and full of ideas.
Ethnicity can contribute to this goal. The multiplicity of challenges in research and
health care in multi-ethnic societies are surmountable.
