Insights

Skipping breakfast is linked to overweight and obesity in first-grade girls, but not boys. Further research into sex-based differences is needed for prevention strategies.

Area of Science:

  • Pediatric Nutrition
  • Childhood Obesity Research
  • Public Health

Background:

  • Existing research links skipping breakfast to overweight/obesity in older children.
  • Limited data exists on this association in younger children.

Purpose of the Study:

  • To investigate the association between skipping breakfast and overweight/obesity (OW/OB) in first-grade children.
  • To explore potential sex-based differences in this association.

Main Methods:

  • A cross-sectional study of 4360 Icelandic first-graders (ages 5.6-7.4 years).
  • Breakfast skipping assessed via self-report; OW/OB determined by measured height/weight.
  • Binary logistic regression adjusted for bedtime, school well-being, commuting, and physical activity.

Main Results:

  • 7.2% of boys and 7.5% of girls reported skipping breakfast.
  • A significant association between skipping breakfast and OW/OB was found in girls (OR 1.66).
  • No significant association was observed in boys (OR 1.02).

Conclusions:

  • Skipping breakfast is associated with overweight/obesity in first-grade girls in Iceland.
  • Sex-based differences in the breakfast-obesity link warrant further investigation.
  • Findings may inform targeted strategies for preventing childhood obesity.

Obesity01:24

Obesity

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...

Cause and Effect01:53

Cause and Effect

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?

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...

Stress Prevention and Stress Management Techniques IV01:26

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...
