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 from...
Correlations02:20

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
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.
Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Summary

Adolescent fruit and vegetable intake is mostly individual, with limited school influence. Family-based interventions are key, as school success depends on parental involvement for children

'Boden Food Plate': Novel Interactive Web-based Method for the Assessment of Dietary Intake

Published on: September 18, 2018

Area of Science:

  • Pediatric Nutrition
  • Public Health
  • School Health Programs

Background:

  • Adolescents often have insufficient daily intake of fruits and vegetables.
  • Understanding factors influencing children's dietary habits is crucial for public health initiatives.

Purpose of the Study:

  • To investigate the influence of school environment on 11-year-old students' fruit and vegetable consumption.
  • To determine the proportion of variance in intake attributable to individual, family, and school factors.

Main Methods:

  • Utilized data from the European 2003 Pro Children Survey in Denmark.
  • Employed multilevel logistic regression with matched student-parent-school data (N=1410) from 59 schools.
  • Analyzed fruit and vegetable intake separately, considering individual and school-level covariates.

Main Results:

  • 40% of students consumed >= 200g fruit/day; 25% consumed >= 130g vegetables/day.
  • Most intake variance (93-98%) was at the individual level, with minor school-level effects.
  • School food availability showed varied effects, particularly for boys and students from high-availability homes.

Conclusions:

  • School environment has a limited impact on adolescent fruit and vegetable intake.
  • Family-level interventions are likely more impactful than school-based ones alone.
  • Parental involvement is critical for the success of any school-based dietary interventions.
