You have successfully identified and described the factors and risk which
can affect your client‟s health and well-being. Now you are going to
measure just how fit and healthy your client is. To do this you are going
to use up to four different measures of health.
1.       Body mass index
2.       Height/weight charts
3.       Harvard Step Test
4.       Peak Flow

Use the body mass index information sheet to help you complete this
1. Explain what Body Mass Index is, what it measures and how it is
calculated.
2. Calculate your client‟s body mass index using the worksheet.
or OK? Eg, if your client is overweight you need to explain why this is
putting their health at risk.
4. Check your calculations by logging onto
www.eatwell.gov.uk/healthydiet/healthyweight/bmicalculator

1.   Explain what height/weight charts are and why they are used.
2.   Either use the chart you have been given or find one on the internet
(www.eatwell.gov.uk) to mark your clients height/weight on it.
3.   Explain what your results mean and which category your client falls
into.
4.   Explain the implications for their health, and whether their health is at
risk.

Use the information sheet to help you. Explain what the Harvard Step
Test is. Follow the instructions for the Harvard Step Test and ask your
client to carry it out.

If your client is a smoker or lives with a smoker you could use peak flow
as a measure of health. Use the worksheet „What is Peak Flow‟ to help
you.

You have used four measures of health to assess your client‟s health and
well-being. Now do the following.

Choose one or two of these measures of health and describe them in
detail, making sure you include any calculations.

Draw conclusions from these results. Comment on your client‟s physical
health. For example, “From the results of my client’s BMI assessment, I have
discovered that they fall into the over-weight category. This means that
………………………….., and my client could be at risk of ……………”

BODY MASS INDEX

In adults the relationship between height and weight can be an indicator of good or ill health. A
person‟s weight should be in proportion to their height as shown in the height-weight charts. A person
is considered obese when their weight is more than 20% above the average weight for people of the
same height and similar cultural background

BMI assesses whether a person is underweight, normal, overweight, or obese. It measures the
amount of fat in a person in relation to his or her height. BMI is less accurate for athletes or those who
are very muscled because muscle weighs more than fat. Such people can appear in a higher BMI
category despite having a healthy level of body fat. The BMI is not accurate for women who are
pregnant or breastfeeding, or for people who are frail.
The BMI Calculator is only one guide to a person‟s overall health. Waist measurement, body fat level,
blood pressure, cholesterol, physical activity, smoking and the healthiness of the diet are also
important. A BMI assessment is not the same as a height-weight assessment.

BMI is assessed by using the following calculation:

Weight (kg)           = BMI
Height (m) x Height (m)

TRY IT FOR YOURSELF
Using the formula above work out the BMI for the following people. Round up your results to the
nearest whole figure:

4.      Working with 3 friends collect information about each other‟s height and weight in feet and
inches and stones.

Height (feet & inches)            Weight (stones and
pounds)

Person 1

Person 2

Person 3

Person 4

Now convert this into metric

Change their weight into pounds (lbs) and then divide that by 2.2 to convert it into kilograms.
Weight 1 kg = 2.2 lbs
1 stone = 14 lbs

Example: client‟s weight =8 stone 6lbs
To convert to pounds do the following:
8 x 14 = 112 + 6 = 118 lbs

Now to convert this to kilograms:
divide 118 by 2.2
118  2.2 = 53.636 (round this up to 2 decimal places)

5.       Now calculate your clients BMI using the formula given above.

6.       What conclusions can you draw from this result?

7.       Could their BMI affect their health and well-being? If so, how?

INFORMATION SHEET

Height and Weight

A person‟s weight should be in proportion to their height and this can be a good indicator of an adult‟s
health. They are standard ways of measuring a person‟s weight against their height. To do this
standard charts are used which take into account the person‟s frame size. Frame size s is a person‟s
bone size and build. Different tables are used for men and women.
A person will be considered OBESE if their weight is 20% or more above the average weight for
people of the same height. If someone falls into the severely overweight range then they are at risk
of:
        Cardiovascular disease
        High blood pressure
        Diabetes
        Arthritis and other conditions.

Moderately overweight people are still at risk and should follow the same plan as severely overweight
people.

Slightly overweight people are still at a greater risk than those of normal weight, but should follow a
sensible weigh-reducing plan and take more exercise.

Being slightly underweight is not a problem but being very underweight is a problem.

1.       What category does your client fall into?

2.       Is this a factor which could affect your client‟s health and well-being?

3.       If so what health risks are they facing?

See the weight and height table overleaf.

Harvard Step Test

The Harvard Step Test measures your endurance (stamina) fitness level. It tests how quickly
your heart rate returns to its resting rate after exercise. The more quickly the heart rate returns
to its resting rate the fitter your client is.

You need to be able to measure your pulse to do the Harvard Step Test. Ask your teacher to
show you how if you are not sure how to do this.

How to carry out the Harvard Step Test
Work in pairs. You must step up and down on to a 50 cm step (if possible). You must:
        Step up with one foot
        Step up with the other foot and stand straight
        Step down with the first foot
        Step down with the other foot and place both feet side by side.

To calculate a person‟s fitness indexes carry out the following exercise.
        0 – 4 minutes – step up and down
        Rest for 1 minute
        Take their pulse for 30 seconds
        Rest for 30 seconds & record their score
        Take their pulse for 30 seconds
        Rest for 30 seconds & record their score
        Take their pulse for 30 seconds
        Record their score
        Record all 3 scores in the table below.

1. Length of exercise in seconds

Peak Flow

A peak flow meter is a special kind of Spirometer, an instrument that measures the breathing
rate and volume of air taken in by a person during each breath. They are used to see how
effective a person‟s lungs are. The peak flow meter usually measures the maximum rate at
which air is expelled from the lungs when a person breathes out as hard as they can. This is
called forced vital capacity. This is an example of a pulmonary function test, because it
measures lung function.

To measure peak flow you will need a peak flow meter, which will record the maximum speed
at which air can flow out of the lungs. The measurement is used to assess the width of the air
passages (the bronchi).

The most common use of peak flow measurement is to monitor the narrowing of the air
passages in people who suffer from asthma. It is also a useful measurement in people who
have respiratory problems such as coughing or difficulty with breathing.

The peak flow meter can be use to diagnose whether someone has a problem with their lungs
by comparing their score with a chart of expected scores. You could use peak flow to measure
your client‟s health, especially if you have a peak flow meter at home. This is a good measure of
health to use if your client is a smoker.

How to Use the Peak Flow Meter
Your peak flow is a measure of how much air you can push out of your lungs with maximum
effort. Below are simple instructions for using a peak flow meter. Be sure to write down your
results.

    Move the marker to 0 or to the lowest point/position on the scale.
    Stand.
    Make sure you're in the same position each time you test.
    Take in as deep a breath as you can.
    Put the mouthpiece of the peak flow meter in your mouth between your teeth.
    Close your lips tightly around it.
    Be sure your tongue does not block the opening. Blow into the mouthpiece once, as
hard and as fast as you can.
    Take the peak flow meter out of your mouth.

Peak Flow as a Measure of Health
If you are to draw conclusions about your client you have to compare their peak flow to the
expected range for someone of the same sex, age and height.
