Summary
This summary is machine-generated.Campus green spaces (GSs) promote physical activity and well-being in college students. Subjective GSs exposure was more strongly linked to health outcomes than objective measures, highlighting the importance of perceived access and use.
Area Of Science
- Environmental Psychology
- Urban Planning
- Public Health
Background
- Sedentary lifestyles among college students negatively impact physical and mental health.
- Campus Green Spaces (GSs) are vital for promoting physical activity and student well-being.
- Existing research often overlooks the nuanced spatial aspects of GS exposure within campuses.
Purpose Of The Study
- To develop and apply a framework for assessing both objective and subjective Green Space (GS) exposure in university residential areas.
- To investigate the associations between GS exposure, physical activity, social cohesion, and perceived health among college students.
- To elucidate the mediating mechanisms linking GS exposure to student health outcomes.
Main Methods
- Developed a multi-dimensional objective assessment framework (2D, 2.5D, 3D) using spatial analysis, deep learning, and UAV technology.
- Incorporated subjective metrics including GS visiting frequency, duration, and perceived quality via questionnaires.
- Utilized Generalized Linear Models (GLM) and Structural Equation Modeling (SEM) with path analysis on data from 820 university students.
Main Results
- Objective 2D GS area within a 100m buffer showed significant health associations.
- Path analysis revealed GS area influences health through physical activity and social cohesion.
- Subjective GS exposure metrics demonstrated stronger exposure-response relationships than objective measures.
Conclusions
- Both objective and subjective measures of Green Space (GS) exposure are important for understanding student health.
- Subjective perceptions of GS exposure appear more critical in driving health benefits.
- Findings offer practical insights for designing health-promoting campus environments and optimizing GS planning.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...
