Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Psychosexual Theory of Development01:14

Psychosexual Theory of Development

Sigmund Freud's psychosexual theory of development suggests that early childhood experiences significantly shape personality and behavior. Freud proposed that development is discontinuous, occurring in five distinct stages, each defined by a focus on different erogenous zones. He believed that failure to resolve the conflicts specific to each stage successfully could result in fixation, potentially influencing behavior as adults.

Anorexia Nervosa01:28

Anorexia Nervosa

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.

Self-Schemas02:16

Self-Schemas

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.

Area of Science:

  • Nutrition Science
  • Developmental Psychology
  • Public Health

Background:

  • Eating behavior develops early, influenced by complex biological, familial, social, and environmental interactions.
  • Understanding these early determinants is crucial for preventing chronic diseases and promoting lifelong healthy eating patterns.

Purpose of the Study:

  • To synthesize evidence on early-life factors influencing eating behavior and dietary intake from infancy through adolescence.
  • To propose a framework integrating key determinants and their impact on eating patterns.

Main Methods:

  • A narrative review approach was employed, prioritizing longitudinal studies, intervention trials, and policy evaluations.
  • Cross-sectional evidence was used to describe patterns and sociodemographic factors.

Main Results:

  • Breastfeeding, responsive complementary feeding, and self-regulatory parenting foster responsiveness to internal cues and preference for nutrient-dense foods.
  • Coercive feeding, early exposure to palatable foods, and marketing contribute to hedonic eating and impulsive consumption.
  • Family stress, food insecurity, and access to unhealthy foods increase vulnerability to poor eating habits and emotional eating in adolescence.

Conclusions:

  • Preventive interventions should integrate parenting support, school food education, digital marketing regulation, and promotion of healthy food environments.
  • Understanding the multifaceted factors linking early determinants to eating behaviors is essential for fostering a balanced relationship with food and preventing early-onset chronic diseases.
