まとめ
構造的な人種差別は 歴史的な権利剥奪と 現代的な不利な状況で測定され 過剰な死亡率に大きな影響を及ぼします これらの要因を区分することで 総合的な測定よりも 健康格差の理解が より明確になります
科学分野:
- 公衆衛生
- 都市研究
- 健康に関する公平性
背景:
- 人種差別的な都市開発と市政政策は アメリカで貧困のサイクルを永続させています
- 複合社会経済的変数はしばしば社会決定因子の時間的側面を覆う.
- 構造的な人種差別が 健康に与える微妙な影響を 理解することが重要です
研究 の 目的:
- 歴史的な権利剥奪と現代の不利な状況が 過剰な全因死亡率に及ぼす影響を区別する.
- COVID-19 パンデミックの間,米国の都市環境における健康結果に対する構造的人種差別の影響を評価する.
- 医療研究における社会経済学的変数の有用性を検証する.
主な方法:
- カンザス・シティ・メトロポリタン・エリア・ZIPコード・タブレーション・エリア (ZCTAs) の210の歴史的権利剥奪と現代の不利な指標を開発した.
- 平均と平均以上のインデックススコアに基づいてZCTAを分類するために象限行列を使用した.
- AICを用いたモデルフィットと比較して,インデックスとすべての原因による過剰死亡率の関係を分析するために一般的な線形モデルを使用した.
主要な成果:
- 平均以上の構造的人種差別マーカーを持つ ZCTA は,すべての原因による過剰死亡率が著しく高かった.
- エクスポージャー期間を区分したクアドラントモデルは,結合インデックス (AIC = 3468.3) と比較して優れた性能を示した.
- AICの有意な減少を示し,より優れた説明力を示した.
結論:
- 複合的な指標は 構造的な人種差別が 健康にどう影響するかという 重要な違いを隠すことができます
- 健康格差を正確に評価するには 場所に基づいた歴史的に敏感な健康研究が不可欠です
- 構造的人種差別への曝露期間を区分することで,過剰な死亡リスクをより正確に理解できます.

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...

Schemas
12.0K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Fundamental Attribution Error
13.2K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Stereotype Content Model
14.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Structuralism
1.1K
Structuralism, an early psychological theory developed by Wilhelm Wundt and his student Edward Bradford Titchener, sought to dissect the human mind into its most fundamental components. Wundt's groundbreaking work in his laboratory set the stage for Titchener to define structuralism's goal as cataloging the "atoms" of the mind—sensations, images, and feelings—akin to how chemists identify elements of matter.
Titchener's approach to structuralism was unique. He...

Bias in Epidemiological Studies
671
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:
