Children

Area of Science:

  • Environmental health
  • Childhood obesity research
  • Urban planning and public health

Background:

  • Conflicting research exists on the link between neighborhood environments and children's weight.
  • Effective interventions require a clearer understanding of these associations.

Purpose of the Study:

  • To examine the relationship between food and physical activity (PA) environments and children's weight status.
  • To investigate factors contributing to discrepancies in previous study findings.

Main Methods:

  • Assessed weight status in 702 children (ages 3-18) in four New Jersey cities.
  • Utilized parent-measured height and weight data (2009-2010).
  • Employed geospatial analysis to measure proximity to food and PA outlets relative to residences.

Main Results:

  • Increased proximity to convenience stores (1/4 mile) was associated with higher odds of overweight/obesity (OR=1.9).
  • Presence of a large park (1/2 mile) was associated with lower odds of overweight/obesity (OR=0.41).
  • No significant associations found for other food or PA outlets.

Conclusions:

  • Specific food and PA environmental features predict children's weight status.
  • The detectability and nature of these relationships are influenced by community-specific geospatial characteristics.

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 adipocytes...
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...
Gene-Environment Interactions01:20

Gene-Environment Interactions

Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
Regulation of Food Intake01:30

Regulation of Food Intake

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...
Lifestyle Factors and Health01:20

Lifestyle Factors and Health

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...

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
