Convenience Sampling Method00:55

Convenience Sampling Method

11.9K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Cross-Sectional Research01:50

Cross-Sectional Research

12.8K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

411
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Binge Eating Disorders01:23

Binge Eating Disorders

592
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...

Regulation of Food Intake01:30

Regulation of Food Intake

3.0K
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...

Nature and Nurture01:10

Nature and Nurture

22.6K
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,...

Area of Science:

  • Pediatric Nutrition
  • Dietary Trends
  • Public Health

Background:

  • Snacking contributes significantly to calorie intake in American children.
  • The energy density of snacks consumed by US children has risen over recent decades.

Purpose of the Study:

  • To analyze long-term trends (1977-2014) in snack energy density and food sources among US children.
  • To investigate disparities in these trends across various socio-demographic groups.

Main Methods:

  • Utilized data from eight national food intake surveys (n=49,952 children aged 2-18).
  • Examined snacking patterns, energy intake from snacks, and snack food/beverage sources.
  • Analyzed trends across race-ethnic, age, gender, education, and income demographics.

Main Results:

  • Per capita energy intake from snacks significantly increased across all groups (P < 0.01).
  • Salty snack consumption doubled; sugar-sweetened beverage intake decreased overall but rose among Non-Hispanic Blacks.
  • Children in lower poverty and education groups showed over 100% increase in snack calorie intake.

Conclusions:

  • Snacking behaviors and sources vary by socio-demographic factors in US children.
  • Snacking remains a major dietary component, often with unhealthy food choices not aligned with US dietary guidelines.
