Summary
The Water First intervention costs $20 per student for school-level and $131 per student for classroom-level implementation. Annualized, the school-level intervention costs $11 per student, offering valuable insights for promoting water access in schools.
Area of Science:
- Public Health
- Health Economics
- School Health Programs
Background:
- Inadequate access to free drinking water in schools impacts student health.
- Water First is a school-based intervention proven effective in preventing overweight.
- The cost-effectiveness of Water First has not been previously quantified.
Purpose of the Study:
- To evaluate the costs associated with the Water First intervention.
- To determine the cost per student for school-level and classroom-level interventions.
- To provide cost insights for implementing school water access programs.
Main Methods:
- Secondary analysis of a cluster-randomized clinical trial data.
- Systematic capture of activities, resources, and labor, material, and utility costs.
- Cost estimation per school and per student over one academic year.
Main Results:
- The Water First intervention cost $20 per student (school-level) and $131 per student (classroom-level) annually.
- The annualized cost for the school-level intervention, considering equipment lifespan, was $11 per student.
- Costs were calculated in 2023 US dollars.
Conclusions:
- The cost estimates offer valuable data for schools and stakeholders.
- Informed planning and implementation of effective school water interventions are facilitated.
- Promoting access to drinking water in schools is crucial for student well-being.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

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...

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
