概括
包括种族/种族在内的过度负担社区 (OBC) 的定义显示,空气污染物暴露的差异更大. 没有重大干预,这些不平等预计会随着时间的推移而恶化,影响公共卫生.
科学领域:
- 环境健康 环境健康
- 环境正义 环境正义
- 公共卫生政策 公共卫生政策
背景情况:
- 在减少空气污染和减轻不同健康影响方面,地理特定的战略至关重要.
- 国家立法使用各种定义来识别具有高污染物水平和特定人口特征的地区,但其有效性尚不清楚.
研究的目的:
- 评估不同立法定义的负担过重社区 (OBCs) 如何捕捉过多空气污染物的地区.
- 评估这些定义对减少空气污染暴露和健康不平等的影响.
主要方法:
- 使用累积影响框架从州立法中提取OBC定义 (2024年5月之前).
- 在人口普查区组 (CBG) 层面上分析了密歇根州PM2.5度与常见OBC指标的相关性.
- 在各种干预场景下,利用通用线性混合模型预测2019-2039年PM2.5差异.
主要成果:
- 包括种族/种族在内的OBC定义显示,与基于收入的定义相比,PM2.5差异显著更大.
- 预测模型预测,在当前和中等加速干预场景下,所有OBC定义的PM2.5不平等性随着时间的推移而增加.
结论:
- 当OBC定义包括种族/种族时,PM2.5度差异最明显.
- 如果不将目前的减排率提高一倍或四倍,则不太可能消除种族/种族定义的OBCs的暴露不平等,这凸显了需要更强有力的环境正义政策的需要.

Community Based Intervention
264
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
272
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Strategies for Assessing and Addressing Confounding
345
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Impact of Social Context on Individuals
266
Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

Drug Control Governance: Regulatory Bodies and Their Impact
473
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...
