Summary
School-based body mass index (BMI) measurement is accepted for surveillance but controversial for screening. More evaluation is needed to confirm if BMI screening effectively addresses youth obesity.
Area of Science:
- Public Health
- Pediatrics
- School Health Programs
Background:
- School-based body mass index (BMI) measurement is a widely discussed strategy for addressing youth obesity.
- Concerns exist regarding its implementation and effectiveness.
Purpose of the Study:
- To describe the purposes of BMI measurement programs in schools.
- To examine current practices, research, and expert recommendations.
- To identify concerns and provide guidance for implementation.
Main Methods:
- An expert panel convened by the CDC reviewed and provided input on the article.
- The panel included experts in public health, education, counseling, medical care, and parent advocacy.
- The article synthesizes existing research and expert opinions.
Main Results:
- BMI measurement for surveillance (population-level risk identification) is widely accepted.
- BMI measurement for screening (individual assessment and parental notification) is controversial.
- Further evaluation is required to determine the efficacy of BMI screening programs.
Conclusions:
- BMI screening partially meets criteria for school-based health screenings.
- Schools should evaluate program impact on BMI, knowledge, attitudes, and behaviors.
- Safeguards, supportive environments, and evidence-based strategies are crucial for successful programs.

01:19Mass and Weight
Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the acceleration due to...

01:24Obesity
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...
01:52Atomic Mass
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which are...
01:10Units and Standards of Measurement
A physical quantity is defined either by specifying its measurement method or by stating how it is calculated from other measurements. For example, consider a metallic cube. We might define its mass and dimensions by specifying methods for measuring them, such as using a weighing machine and a meter scale. Then, we could define the volume by stating that it is the cube of its side, and we could calculate the density as the mass divided by the volume.

01:54Molar Mass
The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.
