概括
食品上的健康标签可能无法有效减少肥胖. 事实上,像NHS认可一样,高可信度的标签可能会无意中增加不健康产品的销量,这表明潜在的"反弹"效应.
科学领域:
- 公共卫生 公共卫生
- 行为科学 行为科学
- 食品市场营销 食品营销
背景情况:
- 越来越多的不健康食品的可用性和低成本对全球肥胖流行病作出了重大贡献.
- 通过食品标签向消费者提供咨询是缓解这一问题的潜在策略.
- 健康标签的有效性可能取决于提供建议的来源的可信度.
研究的目的:
- 调查是否提高食品标签上的健康建议的可信度,提高其在影响消费者选择方面的有效性.
- 为了确定具有更高来源可信度的标签是否会导致更健康选择的销售增加.
主要方法:
- 在医院环境中使用自动售货机进行了一项研究,储存健康和不健康的产品.
- 健康产品被分配到三个条件之一:没有标签 (控制),低可信度标签 ("更轻松的选择") 或高可信度标签 (英国国家卫生服务 - NHS - 认可).
- 产品的销售量被衡量为主要结果.
主要成果:
- 没有观察到标签对销售额的总体主要影响.
- 在标签,自动售货机位置和支付类型之间发现了显著的相互作用.
- 在特定的背景下 (一个地点和支付类型),高可信度的标签导致销售额增加,包括不健康的产品,与预期的效果相反.
结论:
- 具有高来源可信度的健康标签 (例如NHS认可) 可能会产生最小的影响或可能"反弹",导致不健康食品消费的意外增加.
- 该研究的结果表明,健康标签的设计和实施需要仔细考虑,以避免不良影响.

The Availability Heuristic
6.0K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Stereotype Content Model
14.7K
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...

Criteria for Causality: Bradford Hill Criteria - II
313
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Cause and Effect
10.9K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Errors occurring during blood pressure monitoring
726
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
4.2K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
