I will look at the following areas:

I have decided to look at this issue because I think it is a problem for the future generations and that creates lots of problems. I also think that

Currently my opinion is yes because more people are becoming obese and this can lead to a higher risk of heart attack and a stroke that can soon be top killers.

This topic links with the GCSE course unit on Culture and Beliefs. This is because it is a controversial issue, which has

I define obesity as a condition, which holds excess weight, and causes negative problems which affects your body badly, e.g. obesity can lead to a stroke and can cause heart attacks. People who are obese at 40 can lose up to seven years off their life, research has found. The findings mean that being fat in a middle age increases the risk of dying sooner then a slim non-smoker.

Obesity is defined as having a body-mass index (BMI) of 30 or above. Doctors consider a BMI of 25 or under to be healthy.

The number of people who are obese has tripled over the last 20 years, and is still raising saying experts.

Around one in four men and one in three women in the UK are overweight. While slightly more women than men are obese, in the last ten years there has been a greater increase in the number of men who are obese.

The NHS spends at least �500m a year on treating obesity, which could also be costing the economy over �2bn a year. If the rise continues, it could cost the economy �3.5bn a year by 2010.

Experts for the rise in obesity blame the combination of a less active lifestyle and changes to eating patterns.

Coronary heart disease causes 270,000 heart attacks each year in the UK. Of these, the British Heart Foundation (BHF) estimates that 28,000 are directly attributable to obesity.

This subjects interests me because I here news daily on this subjects on the news and documentary’s. I think if there is lots of data being shown everywhere then this can help me gather facts easier

Chapter 2: Methodology:

There are advantages of each primary and secondary methods and I have sorted these out

Primary research

Questionnaires

* Good way to obtain quantitative data

* Use if the same questions make analysis easier

* Can cover a larger target audience over a wide area

However

* Can be time consuming to collect

Focus groups

* Good for testing out new ideas or products

* Compared to observation, a focus group enables the researcher to gain a larger amount of information in a shorter period of time

However

* Depends on the skill of the researcher

* Not necessarily of the whole production

Secondary research

Books

* Useful to refer back to on a regular basis

However

* Can be expensive

Journals

* Useful for current issues and information

Newspaper

* Useful for current issues on the day

* May provide food for thought

Television

* Strong pictorial images that can stimulate ideas for study

* Provides a deeper detailed research into the story

However

* Difficult to refer back to (unless the programme was recorded)

Statistics

* Useful for qualitative analysis of data

* Can provide more factual evidence

* Can help to provide evidence of trend

The Internet

* Worldwide information provided from everyone

However

* Usually too much information

* Not always up to date or reliable

Chapter 3

Obesity has already hit America with all the fast food chains. There are over 233 different fast food chains and is on an increase. Already a quarter of the adult population in England is classified as obese and almost a fifth of all children under the age of 16 are obese, this is a major problem for all the future of Britain.

BMI

You are in the normal range if your bmi is between 18.5 and 25(kg/m2)

You are overweight if your bmi is between 25 and 30

You are obese if your bmi is 30 or higher

You are morbidly obese if your bmi is 40 or higher

If your BMI is between 17 to 22, your life spam might be longer then average. Men are usually satisfied with a BMI of 23 to 25 and women tend to believe they look their best at values between 20 to 22

Of people think there is an

Increase in obesity, this show

That they are aware of an increase.

Questionnaire analysis

I think the results I have received have given me and idea that people can define obesity and can give me their views on obesity. However I think I can improve the quality of my questionnaire and ask questions like ”also I could have interviewed a range of people which eliminates unintentional subjectivity and bias results. Asking more people can also make my results a bit more accurate if I interviewed them quicker. I don’t think my data produced valid data because when asking for some people they often came out in the same kind of social-economic groups, this can cause conformity and make people choose what their friends chose, and also I occasionally got the same kind of gender groups and same ages which can affect the overall results

The length of time conducting interviews means that my research findings could only be based on a small sample of respondents. This has affected the reliability of my conclusions, although I feel that the views expressed have not been greatly compromised any questionnaire may have inherent bias results.

Chapter 4: evaluation

1. My sampling methods

I think my sampling methods should have had an improvement, so in order to improve the validity of my results a more accurate sampling method such as systematic or random sampling should have been used. Most professional surveys use a wide variety of people and uses over hundreds of people to do there surveys which creates a much more accurate results, a wide range of answers and random sampling which makes the results not biased, so my sample size of 48 means that my conclusion may be limited accuracy, this is serious limitation of my research.

2. My Questionnaires

There were several problems with my questionnaire that may have led to inaccurate results. These include improving my questions so it’s more open and have much more choices.

There were advantages and disadvantages in my questionnaire

Advantages:

1. cover a large number of people

2. large amounts of info can be gathered quickly

3. they can help to reduce the bias of interviews

Disadvantages:

1. closed questions may not reflect on respondents real views

2. bias may be presented through the choice of questions asked

3. badly phrased questions might influence the answers given
