Summary
Adolescents
Area of Science:
- Environmental health
- Urban planning
- Adolescent health
Background:
- Existing neighborhood definitions lack youth perspectives.
- Few studies explore youth-perceived neighborhood boundaries.
- This research contrasts youth-identified neighborhood (YIN) with census-defined neighborhood (CDN) boundaries.
Purpose of the Study:
- To compare youth-identified neighborhood (YIN) boundaries with census-defined neighborhood (CDN) boundaries.
- To analyze time spent and moderate-to-vigorous physical activity (MVPA) within both boundary types.
- To assess the validity of YIN as a measure of adolescent environmental exposure.
Main Methods:
- Adolescents (11-14 years) mapped their neighborhoods.
- Global Positioning System (GPS) and accelerometers tracked location and physical activity.
- Paired analyses compared time spent and MVPA within YIN and CDN.
Main Results:
- YIN and CDN areas were similar (p=0.30).
- Adolescents spent significantly more time in YIN (80.3%) vs. CDN (58.4%) (p<0.0001).
- MVPA was higher in YIN (14.7 min) vs. CDN (9.5 min) (p<0.0001), with greater MVPA density in YIN (p=0.02).
Conclusions:
- Adolescents' perceived neighborhoods are similar in size to census definitions.
- YIN better reflects adolescents' actual time use and physical activity spaces.
- Youth-identified neighborhood mapping is a valuable tool for understanding adolescent environments and activity.

Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die out.
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

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...

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...
