Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

91.4K
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...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

675
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Actuarial Approach01:20

Actuarial Approach

133
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

196
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Applications of Life Tables01:22

Applications of Life Tables

123
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Surveys02:16

Surveys

15.4K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Summary
This summary is machine-generated.

Systemic racism in the US, particularly cultural racism, impacts health. A new measure links cultural racism to increased deaths and reduced life expectancy for Black and white adults.

Area of Science:

  • Public Health
  • Sociology
  • Health Disparities

Background:

  • Systemic racism drives racial disparities in the US.
  • Structural and interpersonal racism are recognized, but cultural racism lacks a validated measure.
  • Cultural racism involves societal beliefs and ways of life contributing to health inequities.

Purpose of the Study:

  • To develop and validate a measure for cultural racism.
  • To examine the association between cultural racism and mortality.
  • To assess the impact of cultural racism on life expectancy.

Main Methods:

  • Confirmatory factor analysis was used to create a cultural racism latent measure from nine indicators.
  • US mortality data from 2018-2021 from the CDC WONDER system were analyzed.

  • Statistical analysis examined the association between the cultural racism factor and mortality/life expectancy.

    • Main Results:

    • Each unit increase in the cultural racism factor was linked to approximately 136 additional all-cause deaths per 100,000 population.
    • A one-unit increase in the cultural racism factor was associated with a one-year decline in life expectancy.
    • These associations were consistent across both Black and white adults.

    Conclusions:

    • The developed cultural racism measure advances the science of racism and health.
    • Findings provide an empirical basis for interventions addressing US health inequities.
    • Cultural racism is a significant factor contributing to mortality and reduced life expectancy.
