Self-Schemas

35.0K
In general, 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.

Obesity01:24

Obesity

968
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Regulation of Food Intake01:30

Regulation of Food Intake

1.9K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Anorexia Nervosa

579
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Models of Health Promotion and Illness Prevention I

2.5K
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Summary

Food insecurity is linked to obesity through psychological distress and unhealthy eating habits. Understanding these coping mechanisms is key to addressing the complex relationship between food access, diet, and weight management.

Area of Science:

  • Public Health
  • Psychology
  • Nutritional Science

Background:

  • Food insecurity is associated with adverse health outcomes like poor diet and obesity.
  • The psychological and behavioral mechanisms linking food insecurity to these outcomes remain unclear.

Purpose of the Study:

  • To investigate the role of psychological distress and unhealthy coping behaviors in the relationship between food insecurity and obesity.
  • To examine how food insecurity influences diet quality through distress and coping mechanisms.

Main Methods:

  • A study involving 604 adults in the UK, recruited online and at food banks.
  • Data collection included questionnaires on food insecurity, distress, coping behaviors (eating/drinking), diet quality, and anthropometrics (BMI).
  • Structural equation modeling was employed to analyze the hypothesized relationships, controlling for income.

Main Results:

  • Food insecurity was indirectly associated with higher Body Mass Index (BMI) through increased psychological distress and eating to cope.
  • A direct association was found between food insecurity and poorer diet quality, independent of distress and coping behaviors.
  • Maladaptive coping mechanisms, such as eating high-calorie foods, partially mediate the link between food insecurity and BMI.

Conclusions:

  • Psychological distress and unhealthy eating behaviors are significant mediators in the association between food insecurity and obesity.
  • Food insecurity directly impacts diet quality, but this effect is not fully explained by psychological distress or coping strategies.
  • Findings offer insights into the psychological experience of food insecurity and highlight the role of maladaptive coping in diet-related health issues.
