Hello Students and Parents,
This is a reminder that July 8th, students will be participating in a lesson which they will calculate their BMI. Smelly shoes aren't a big deal but just to let you know, shoes do have to come off for this assessment. Also, bring a pen and paper to class becuase we will be calculating our BMI using a mathematical formula. Read this blog to familiarize yourself with BMI and how you can use it to monitor your health.

Hello students and parents
July 22nd, BMI Lab
This is just a reminder for students to remember that tomorrow we are going to be taking our second round of BMI data. Again, remember to wear socks with your sneakers, and pick your non-smelly pair to avoid any embarrassment. We will be meeting outside the fitness room of the OCC gymnasium at 845 to get height and weight measurements. Also avoid eating a big meal before being measured. All data is totally confidential, and students have full privacy during the measurements. The data being collected is to help students understand the importance of physical activity and a healthy diet. It is not a test to distinguish between people of different sizes. The data collected will help students to show their improvement over the semester. If there are any questions, contact me through email at jared.bowen81@gmail.com

What is BMI?
BMI, or Body Mass Index is a measure of someone's weight in relation to height. To calculate one's BMI, multiply one's weight in pounds and divide that by the square of one's height in inches. People considered to be overweight have a BMI greater than 25. People considered to be obese have a BMI greater than 30. BMI is a reliable indicator of weight related health issues. It uses a mathematical formula using height and weight to calculate a number that is then pugged into a chart that indicates whether someone is underweight, normal, at risk for overweight, or overweight compared to age.
BMI Calculations (English Formula)
[Weight in lbs/(height in inches)squared] X 703
Example: Mr. Bowen is 215 lbs and his height is 72 inches
and his age is 28
[215 lbs/ (72inches)squred] X 703 = 29.1
Mr. Bowen's BMI = 29
Plug the number 29 in the chart with the age 28, and you find what category Mr. Bowen is considered by percentile. Mr. Bowen falls into the 95th percentile which is considered to be overweight.
For class purposes the overweight and obese categories will be called, "Needs Improvement." This will make it so students do not feel embarrassed. Also, when the calculations are done in class, students will have rights to complete privacy. The teacher will be the only person to see their BMI's.

When will the BMI take Place? What preparations do Students Need?
Students will be expected to remove their shoes, so please be aware of this for July 8th, 2010 in RM 131 of the Gymnasium at Ocean Community College. If there is anything that might make a student feel uncomfortable about removing their sneakers (smelly sneakers or socks with holes), make sure this is taken care of for July 8th. Also avoid eating a big meal before taking the BMI.

Test Validity and Reliability
Test Validity
Using BMI in schools for age groups is not done to measure the fat content in students. It also is not a valid measurement to judge weight classifications of students. The purpose of using BMI is that it is a valid measure of weight-related health risks. The BMI’s validity is also supported by its use by NASPE, the CDC, and the Cooper Institute for weight-related health risks.
Reliability
To maintain reliability for BMI, the students took heights and weights every time they did the BMI test. The BMI test had reliable results because the teacher overlooked the measurements for height and weight. Rounding height up and weight down is common to do when people calculate BMI. Factors for test reliability were using the same scale and making students measure both height and weight for both tests. This is to ensure that we were getting accurate data for BMI. Also I double-checked the students’ calculations after they handed them in to ensure they were calculated right.

What you can do to Improve your BMI?
Students can improve their BMI's at home by participating in regular physical activity, and eating a balanced diet will help to improve your BMI. At home students can participate in sports, and other forms of exercise such as running, walking, swimming, callesthenic exercises, and/or any other activity that you can think of to be physically active. Eating healthy is also important. Eating 3 meals a day with snacks in between is a great way to help maintain your BMI.
To put things in perspective, an example to help put an amout of exercise to consuming a food/beverage would be a Coke. To eliminate drinking a bottle of coke, you would have to run 1.5 miles.
In class students will participate daily in various activities that increase their heart rate and utilize numerous muscle groups. Students' BMI's will be compared at periodically throughout the marking period to keep track of improvements.
This lesson will teach students that it is important to maintain a healthy weight. Being over or underweight is bad for your health and can lead to different health problems.
Being underweight was associated with increased mortality compared to normal weight individuals, but from noncancer, non-cardiovascular causes. People who were overweight had more risk of death from diabetes and kidney disease but much less from cancer or cardiovascular disease. In fact, being overweight had the lowest risk of mortality of all the causes. Being obese greatly increased the risk of dying from cardiovascular causes.
So, although it seems like being overweight may not be as serious for health risks as being underweight or obese, there is still an increased risk of diabetes and kidney disease that should be taken into consideration.
