BMI is a value of your weight in relation to your height, regardless of body frame size.

BMI ranges are:
If the BMI is less than 18.5, it falls within the
If the BMI is 18.5 to 24.9, it falls in the
or Healthy range.
If the BMI is 25.0 to 29.9, it falls within the
If the BMI is 30.0 or higher, it falls within the
Body Mass Index = BMI
Health care providers use the BMI as an indicator of healthy or unhealthy weights.

The Issue:
Today, about one in three American kids and teens is overweight or obese, nearly triple the rate in 1963.
Among children today, obesity is causing a broad range of health problems that previously weren’t seen until adulthood.
These health problems affect many, if not all, of a body's systems, throughout a lifetime....
This program is designed to let students look at the data and to explore the different facets of obesity in America, especially in relation to obesity's potential effects on Body systems.
"Underweight", "normal", "overweight", and "obese" are all terms for ranges of weight.

Obese and overweight describe ranges of weight greater than what is considered healthy for a given height.
Underweight describes a range lower than what is considered healthy.
Obesity has to do with weight
Teen Obesity trends 1963 to 2008
Low income
Childhood obesity data

Recent Data
Obesity over the years
Circulatory System
Coronary heart disease
Hypertension (high blood pressure)
Dyslipidemia (high total cholesterol or high levels of triglycerides)
A variety of factors play a role in obesity.
It is a complex health issue to address.
Behavior, environment, and genetic factors may have an effect in causing people to be overweight and obese.
The Caloric Balance Equation
Overweight and obesity result from an energy imbalance.
This involves eating too many calories and not getting enough physical activity.
Body weight
is the result of genes, metabolism, behavior, environment, culture, and socioeconomic status.
Behavior and environment

play a large role causing people to be overweight and obese.
What causes overweight and obesity?
Osteoarthritis (degeneration of cartilage and its underlying bone within a joint, esp. knees, hips)
Type 2 diabetes
Liver and Gallbladder disease
Cancers: esophageal, pancreatic, gallbladder, colorectal, kidney. and also thyroid cancer.)
Digestive System
Nervous System
Sleep apnea (stop breathing while asleep)
Lessens respiratory system function
Decreases lung expansion
Respiratory System
Skeletal System
Gynecological problems
(abnormal menses, infertility)
Endometrial and breast cancer
Health Consequences
source: Center of Disease Control and Prevention
Research has shown that as weight increases to reach the levels referred to as "overweight" and "obesity,"* the risks for the following conditions also increases:
Effects on Body Systems
*Overweight is defined as a body mass index (BMI) of 25 or higher; obesity is defined as a BMI of 30 or higher
(stoppage of blood flow to brain)
Reproductive System
(blockage of blood flow to heart)
Know your BMI
Prevent Weight Gain
Balance Calories daily
Get PHYSICAL!! - exercise daily
How much physical activity do children need?
Losing Weight
Getting Started
Keeping It Off ideas
Simple Starter Ideas...
Contributing Factors
Sugar drinks and less healthy foods on school campuses.
Advertising focus on less healthy foods.
Lack of daily, quality physical activity in all schools.
Variation in license regulations for child care centers
No safe and appealing place, in many communities, to play or be active.
Limited access to healthy affordable foods
Increasing portion sizes. Too much food!
Television and media foster inactivity
Lack of breastfeeding support. Breastfeeding protects against childhood overweight and obesity.
