Major Discrimination Experiences, Education, and Genes

|May 31, 2019
Summary
Genetic factors influencing education also increase reports of lifetime discrimination. This suggests a biological basis for discrimination experiences, impacting health and aging.
Area of Science:
- Genetics
- Sociology
- Public Health
Background:
- Educational attainment is linked to discrimination, not protective.
- Genetic factors for education may influence discrimination reports.
Purpose of the Study:
- Examine the genetic roots of education and their link to lifetime discrimination experiences.
- Investigate mediation pathways, including education, and direct genetic effects.
Main Methods:
- Utilized data from the 2010 Health and Retirement Study.
- Employed polygenic scores to measure genetic propensity for education.
- Conducted mediation analysis using counterfactual methods.
Main Results:
- Genetic antecedents of education elevated discrimination reports in both White and Black participants.
- Education partially mediated the genetic influence on discrimination.
- Direct genetic effects on discrimination were observed, particularly in White participants.
Conclusions:
- Lifetime discrimination experiences appear to have partial genetic underpinnings.
- Direct genetic influences may confound previously estimated links between discrimination and health/life course.
- Further research is needed to explore these genetic mechanisms and their implications for healthy aging.

95.0K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

The digestive system is responsible for the ingestion of food, secretion of enzymes, mixing and digesting food, absorption of the nutrients and defecation. The human digestive system consists of two major parts: the gastrointestinal tract and the accessory digestive organs.

01:28Major Losses in Pipes
1.9K
When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

01:27Major Hormones and Their Functions
1.8K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

01:24Generalization, Discrimination, and Extinction
1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...
