Summary
Childhood obesity is a major health concern. This article discusses a campaign against a fast-food outlet near a school, highlighting the negative health impacts of such proximity on children.
Area of Science:
- Public Health
- Epidemiology
- Urban Planning
Background:
- Childhood obesity reached epidemic levels in developed nations by 2011.
- The proximity of fast-food outlets to schools is a growing public health concern.
- Existing urban planning regulations may not adequately address the health implications of food environments.
Purpose of the Study:
- To document a community campaign opposing the establishment of a fast-food outlet near a school.
- To reinforce the epidemiological evidence linking fast-food outlet proximity to negative child health outcomes.
- To advocate for the modernization of planning laws concerning school environments.
Main Methods:
- Case study of a community-led campaign.
- Review and reiteration of existing epidemiological data.
- Analysis of the implications for urban planning and public health policy.
Main Results:
- A successful campaign was mounted to oppose the fast-food outlet construction.
- Epidemiological evidence confirms a detrimental health impact on children attending schools near fast-food establishments.
- The study underscores the need for updated planning legislation.
Conclusions:
- Community action can influence local development decisions impacting child health.
- There is a clear link between the density of fast-food outlets and adverse child health indicators.
- Modernizing planning laws is crucial to protect children from obesogenic environments.

McNemar's Test
McNemar's Test is a nonparametric statistical test used to determine if there is a significant difference in proportions between two related groups when the outcome is binary (e.g., yes/no, success/failure). It is beneficial when we have paired data, such as pre-test/post-test designs, where the same subjects are measured under two different conditions. The test is named after the statistician Quinn McNemar, who introduced it in 1947. It is commonly used in situations where subjects are...
Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the anxiety of...
Robbers Cave
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...
Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Frustration and Conflict: Approach-Approach, Approach-Avoidance
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable options,...

Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
