Placement - My Healthy Balance (Diabetes WA

The documents below provide examples of the work I have completed, so far, as part of my 100 hour placement at Diabetes WA. My task is to develop, implement and evaluate an energy balance toll for the My Healthy Balance program. My Healthy Balance is an interact, online program that promotes health and well-being. The program consists of 8 sessions along with tools to help participants achieve their goals and learn about healthy eating, physical activity and general well-being. The energy balance tool is designed to show participants the relationship between intake, output and energy balance.

Energy Balance Tool - Briefing document

This document was developed to provide the web design company an overview of the tool, its structure and content. Once the web design company receive this document a quote will be developed and I can continue with the rest of my task.

Aim

To develop an interactive tool that encourages participants to make healthy behaviour changes to achieve energy balance.

Objectives

To develop an interactive energy balance tool for participant’s of the My Healthy Balance Program.

  1. To provide participants with healthy food options to assist in achieving energy balance and promote behaviour change.
  2. To provide information on portion sizes and assist participants to recognise the effect of portion size on energy balance.
  3. To provide information on physical activities and assist participants to recognise the effect of physical activity on energy balance.
  4. To assist participants in recognising the number of minutes of physical activity required to meet energy balance for various foods/meals.

Description

This tool is designed to promote behaviour change in order to achieve energy balance among participants. The tool will consist of four components including selecting an unhealthy food item/meal, selecting a physical activity, creating a healthier plate and analysis of portion sizes. Each component will highlight the importance of energy balance, whether or not it has been achieved and provide alternative behaviours that will lead to energy balance.

Rationale

Energy balance occurs when energy intake equals energy expenditure. Providing participants with alternatives to their unhealthy behaviours promotes behaviour change and in turn promotes energy balance.

The internet is an effective setting to reach a large audience and many Australians are capable of using internet-based programs. Developing an interactive, internet-based energy balance tool provides participants with the opportunity to explore various outcomes of altering their food habits and physical activity levels in relation to energy balance, and improving their health and well-being.

Outline of energy balance tool

The tool will be broken down into 4 sections including;

  1. Introduction and choose a food
  2. Choosing a physical activity
  3. Creating a healthier plate with comparison to the original food item/meal in terms of fat, sugar, kilojoules and physical activity requirements
  4. Comparing  portion sizes between original food and smaller version in terms of fat, sugar, kilojoules and physical activity requirements

General recommendations

  • Incorporate a snapshot of the energy balance tool on the My Healthy Balance homepage.
  • Individuals will be required to provide age, height, weight and gender information during My Healthy Balance registration.
  • Allowing participants to use the tool after completion of the My Healthy Balance program. This will allow them to refer back to the energy balance tool whilst encouraging them to review the session components of the program.
  • A small blurb at the beginning of each section will highlight the purpose of the activity and the relevance to energy balance.
  • In all sections a large illustration of a traditional weighing scale will be used to depict energy balance for the individual. Underneath the scale will be a brief description indicating whether the person is balanced or not and a suggestion to improve this.
  • Send to a friend function.
  • Reset button.
  • Ability for participants to select an alternative section i.e. Switch between portion size, physical activity and create a healthier plate.

Introduction and choose a food

This section will incorporate an introduction depicting the aim of the energy balance tool and introducing participants to the concept of energy balance. Participants will be required to select a food item or meal from the list provided. Each food item/meal will have the corresponding kilojoule content and number of teaspoons of fat and sugar provided in a box nearby. The foods/meals in the list will be typical unhealthy foods/meals consumed by a large proportion of the population. An illustration of each food/meal will also be required.

Choosing a physical activity

This section will comprise the selected food/meal illustration (from section 1) and will require the participant to select a physical activity from the list provided and enter the duration in minutes. A brief blurb will state the purpose of this section is to analyse how many minutes of physical activity it will take to burn off the food/meal chosen. The scale illustration will move according to the state of energy balance achieved. Information regarding the state of balance will be displayed underneath the scale illustration and recommendations on how to improve energy balance provided. Four other physical activities from the list will be displayed underneath the scale illustration and allow participants to scroll over each to determine how many more minutes of physical activity is needed to return to energy balance.

Incidental physical activity should also be re-capped in this section and examples of common incidental physical activities provided in the selection list.

The most common physical activities within the Australian population and their associated intensity will be in the selection list including:

General Gardening Light
Brisk Walking Moderate
Cycling for leisure Moderate
Running Vigorous
Aerobics Vigorous
Swimming Vigorous
Netball Vigorous
Tennis Vigorouis


The number of minutes required to ‘burn off’ the selected food item/meal depends on the intensity of the physical activity. The formula below will be used to calculate the number of minutes needed to ‘burn off’ each food item/meal in the food list:

Light intensity physical activity  
12.6 kJ/min
Moderate intensity physical activity 21kJ/min
Vigorous intensity physical activity 
33.6kJ/mi

Presentation of results

This step will show the participant whether they have achieved energy balance. If they haven’t achieved energy balance, 3 options will be offered for them to choose from to ‘bring back the balance’.

Option 1: Creating a healthier plate

Option 2: Compare portion sizes

Option 3: Physical activity

Each of these options is outlined below:

  • Creating a healthier plate with comparison to original in terms of fat, sugar, kilojoules and physical activity requirements
    The section will highlight the healthier food/meal options to the original chosen food. The original food illustration will be seen on the screen along with a blank plate. Illustrations of healthier food options will be provided next to the blank plate encouraging participants to create a healthier plate. The healthy food options must relate directly to the unhealthy option in order to effectively portray the message. Once the healthy plate is constructed the kilojoule content, number of teaspoons of fat and sugar and minutes needed to burn off the food/meal based on the selected physical activity will arise under each plate. The scale illustration will also reflect energy balance of the original plate and the new plate.
  • Compare portion sizes between original food and smaller version
    This section will display the image of the original food/meal selected and an illustration of the same food/meal but a smaller portion size. The kilojoules, number of teaspoons of fat and sugar and the minutes of physical activity required to burn off the food/meal based on the original selection will be provided for comparison.
  • Physical activity
    This section will display the original food item/meal and the original physical activity and number of minutes selected by the participant. The scale illustration will ‘move’ according to the state of energy balance. Underneath the scale illustration will be four other physical activity options from the selection list. These will not include the physical activity the participant originally selected. The participant will be able to scroll over each of the four physical activities to see how many more minutes of physical activity are required in order to achieve energy balance.

Considerations when developing the energy balance tool

  • The number of foods/meals to be included.
  • Deciding which healthy food items correspond to each unhealthy food/meal.
  • Deciding the exact size of the smaller food/meal portion.

Draft - Tool Written Content

The following document includes the written content of the tool. This document has not yet been finalised but a  draft  is presented below.

Introduction

Energy balance is made up of two components; energy in and energy out. ‘Energy in’ includes all the food and drinks consumed, and is measured by the number of kilojoules in each item. ‘Energy out’ is the number of kilojoules burned by your body through physical activity. Energy balance occurs when the amount of food and drink consumed is equal to the amount of energy expended through physical activity. Your body is constantly burning kilojoules, even when you are sleeping. Specific activities burn more or less kilojoules and in turn contribute to your energy balance. A person who sits at an office desk will need to do more physical activity to maintain energy balance compared to a labourer who is lifting, climbing and walking all day. Although increasing physical activity is the easiest way to maintain energy balance, reducing the amount of energy-dense food/drinks consumed is also an effective method.

If more food/drink is consumed than the amount of energy burnt through physical activity your body will be in positive energy balance. If your body remains in positive energy balance over a period of time you will gain weight.

This tool can be used to show you how unhealthy foods negatively affect your energy balance and provide you with simple alternatives to ensure you maintain energy balance. There are three components designed to help you learn about energy balance including;

  • Creating a healthier plate using the alternative foods provided
  • Analysing the benefits of reducing portion sizes of unhealthy foods
  • Increasing levels of physical activity

Each section will show you how the ‘energy in’ and ‘energy out’ reflect energy balance and provide you with simple alternatives that can help you to maintain your energy balance.

Choose a food.

Please choose a food item or meal from the list below. Click each meal category to see a range of foods that you can select from. Once you have selected your food item/meal you will be able to see the number of kilojoules and the number of teaspoons of fat and sugar it contains.

Choose a physical activity.

Now you have chosen your food, please select below a physical activity that you participate in and enter the number of minutes you intend to do the physical activity for.

Physical activity is a broad term and includes many activities. Some of these activities are termed incidental physical activity and include day-to-day activities that you may not consider to be physical activity. Some examples include; parking further away from work and walking the final distance, taking the stairs, walking the dog, gardening and housework. Other physical activities include running, swimming and playing tennis. These activities are planned, structured and exert more effort.

Have a look at the scale illustration below. Has energy balance been achieved?

There are several ways that you can ensure energy balance is met, by choosing a healthier food item, increasing your levels of physical activity or reducing the portion size. You will be able to look at each of these in more detail in the following sections.

Create a healthier plate

This section requires you to analyse your original food item and make a healthier plate from the list of alternatives. Use your mouse to drag the alternatives onto the empty plate to create a meal you enjoy.

Once you have created your plate have a look at the differences in kilojoule content, the number of teaspoons of fat and sugar and the minutes of physical activity required to burn off the foods. Your healthier plate will not only provide you with more nutrients but the levels of fat and sugar will be lower. The kilojoule content of the healthier plate will also be lower, helping you to maintain energy balance.

Given the minutes of physical activity you selected in the ‘choose a physical activity’ section  you can see how reducing your energy intake positively effects your energy balance as you do not need to be as physically active.

Portion size

The larger the food item/meal the more kilojoules it contains and the more physical activity is required to ensure energy balance is maintained. If the combination of your original food item/meal and the number of minutes of physical activity you selected did not ensure energy balance, consider a smaller portion of the food and you will not have to increase your levels of physical activity. This way you can still eat the foods you like while maintaining a healthy weight.

Simply by reducing the portion size you will be significantly reducing kilojoules consumed. Instead of consuming a large amount of a food that you like, cut the serve in half and add some vegetables or fruit to it.

The illustration below shows the difference between your original food item and a smaller version of the item. Look at the difference between the number of kilojoules, the number of teaspoons of fat and sugar in each portion size and the number of minutes of physical activity required to burn off the food in order to maintain energy balance.

Physical Activity

Have a look at the different physical activities below to see how many extra minutes of each you need to take part in to achieve energy balance. Scroll your mouse over each activity to see the minutes of physical activity required.

Intense activities burn more kilojoules meaning you will achieve energy balance sooner. Try a variety of different activities and see which ones you enjoy.

Conclusion

Energy balance is essential to maintain a healthy weight. Positive energy balance will lead to weight gain while negative energy balance will result in weight loss. The concepts covered in this tool are useful to help you maintain energy balance. Eating healthy foods, participating in regular physical activity and reducing portion sizes are simple yet very effective ways to ensure you are achieving energy balance.

 


Pre-testing Energy Balance Tool Brief

This document highlights the need for pre-testing the energy balance tool.

Aim

To assess the effectiveness of the energy balance tool in addressing energy balance.

Objectives of energy balance tool

  4. To teach participants how to use the energy balance tool to monitor personal energy intake and output.
  5. To provide information on portion sizes and assist participants to recognise the effect of portion size on energy balance.
  6. To assist participants in recognising the number of minutes of physical activity required to meet energy balance for various foods/meals.

Brief

To ensure the energy balance tool is meeting its goals pre-testing must take place. Pre-testing opportunities will be advertised on the MHB homepage. Twenty health professionals (who have had experience with the My Healthy Balance program) and twenty My Healthy Balance participants will be required to use the energy balance tool and complete a survey regarding its readability, content, layout and usefulness. A small gift voucher incentive will be offered for participation.

The survey will be designed through survey monkey and all participants must have internet access in order to analyse the energy balance tool and complete the survey. Testing will take place over a one week period commencing on May 7th, 2010.

Results of the survey will be collated and conclusions drawn. Necessary adjustments will be made to the tool before inclusion to the My Healthy Balance program.

Objectives of pre-testing

  1. To determine the readability of the tool.
  2. To determine the relevance of the foods/meals in the selection list to participants.
  3. To determine the relevance of the physical activities to the participants.
  4. To analyse the effect of the information blurbs on participants understanding of energy balance, BMI and portion control.
  5. To determine the effectiveness of using teaspoons as a referral point instead of grams.
