4. Obesity Rates in Australia 42.1% of adult males and 30.9% of adult females were classified as overweight (Body Mass Index between 25.0 and 30.0 kg/m2). 25.6% of males and 24% of females were classified as obese (Body Mass Index > 30.0 kg/m2). The big problem is that it’s getting worst! (http://images.smh.com.au/2011/01/23/2147829/obese-420x0.jpg)http://images.smh.com.au/2011/01/23/2147829/obese-420x0.jpg

5. Obesity Rates in Australia In 2007-08 1, 39.9% of males between the ages of 55-64, 45.1% of males between the ages of 65-74 and 52.8% of males aged 75 years and over, were classified as overweight while 35%, 33.9% and 21.5% respectively, were classified as obese. 1 For females, 34.6% between the ages of 55-64, 42% between the ages of 65-74 and 31.8% aged 75 years and over, were classified as overweight, while 33.4%, 29.4% and 25.1 % respectively, were classified as obese.

6. Obesity Rates in Australia For children and adolescents, the 2007-08 National Health Survey results indicate that 24.9% of children aged 5 – 17 years are overweight or obese. 25.8% of boys and 24.0% of girls are either overweight or obese.

7. Obesity Rates in Australia Once a child is overweight or obese it is unlikely that they will spontaneously revert to a healthy weight, predisposing them to the health concerns listed above for adults. Obese children and adolescents also suffer from an increase in medical conditions. For example, the prevalence of Type 2 diabetes is increasing in children and adolescents. Other problems associated with excess weight in children and adolescence includes the development of sleep apnoea, heat intolerance, breathlessness on exertion, tiredness and flat feet. Some research suggests that obese children (particularly older girls) also tend to exhibit decreased self-esteem and a significant proportion of children use unhealthy dietary practices for weight control http://www.health.gov.au/internet/healthyactive/publishing.nsf/Content/overw eight-obesity http://www.health.gov.au/internet/healthyactive/publishing.nsf/Content/overw eight-obesity

9. What Can we do to Solve This Problem? The best thing that we can do is to stay healthy and maintain a healthy weight.

10. Weight Weight is basically determined by 2 factors. ◦1) Food Intake ◦2) Energy Expenditure If you keep both in check everything takes care of itself.

11. Food Intake Means how much food or drink that you consume (take in).

12. Energy Expenditure Means how much energy you use up during the day.

13. PE Healthy Window Basically there’s 4 different sections of the PE healthy window.

14. Healthy To be healthy you need to have high food intake plus high energy expenditure. So it doesn’t matter what you eat as long as you burn it off, you’ll be healthy.

15. Anorexic Anorexia occurs when people don’t eat enough food but spend too much energy.

16. Obese Obesity occurs when you intake too much food, but don’t expend enough energy.

17. Lazy If you can’t be bothered to eat and can’t be bothered to do any exercise you are lazy!

18. Energy Balance The key to having a healthy weight is to have energy balance.

19. Energy Balance – Weight Gain Think of your body as a piggy bank. As you put more energy into your body, well your piggy bank grows. Only that it’s a bad thing if your body grows too much.

20. Energy Balance – Weight Loss Now think of the opposite. As you use more energy than you put into your body, well your piggy bank shrinks. In real life if you run out of money you are bankrupt.

21. Energy Balance – Weight Stays the Same Your piggy bank will stay the same if whatever energy you put in is the same as it goes out.

22. Assessment Task You now have to design a poster on all of the information that you have learnt in this presentation. The more information you present the better the mark you’ll get. Be sure to decorate it nicely to make it presentable.
