The question I have chosen to investigate is:
Is obesity the next big killer in the U.K?
I will look at the following areas:
> What is obesity?
> Is obesity to blame for all our health problems?
> What is the situation in America?
> My opinion.
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 ï¿½500m a year on treating obesity, which could also be costing the economy over ï¿½2bn a year. If the rise continues, it could cost the economy ï¿½3.5bn 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
* Good way to obtain quantitative data
* Use if the same questions make analysis easier
* Can cover a larger target audience over a wide area
* Can be time consuming to collect
* 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
* Depends on the skill of the researcher
* Not necessarily of the whole production
* Useful to refer back to on a regular basis
* Can be expensive
* Useful for current issues and information
* Useful for current issues on the day
* May provide food for thought
* Strong pictorial images that can stimulate ideas for study
* Provides a deeper detailed research into the story
* Difficult to refer back to (unless the programme was recorded)
* Useful for qualitative analysis of data
* Can provide more factual evidence
* Can help to provide evidence of trend
* Worldwide information provided from everyone
* Usually too much information
* Not always up to date or reliable
Type of data
Purpose of data
To find out peoples opinions
Specific to product to update
People have a lack of knowledge, and can also give false answers due to silliness
Ask more people, different age groups, and better questions.
To find a range of materials on this subject
There is a lot of information to access and a range of opinions
A lot of the informational the internet might not be accurate and biased
Find different websites and see if the data is the same
To find journalist views on the subject
Accurate data collection with realistic facts
Often can have data with peoples opinions which gets confusing
include more of this kind of data can improve my facts and look at other peoples opinions
To find out facts and information on the subject
Get accurate information and views on the subject
Can be produced like 5 or 6 years ago which can then provide information which has changed
Include more of this data because the facts can help provide top information
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.
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
The picture across shows effects caused by obesity.
As you can see the heart is slightly enlarged and is
Harder to pump blood, this causes problems for breathing
And makes it harder to exercise.
The graph below shows levels of obesities in other countries, from the data in the graph below there are more obese females then males in most countries. USA-black results shows that there are far more obese females then males these results are surprising and are interesting. UK results is around average compared to other major countries, with averages of 16% for males and around 17% for females
(right)in this graph the majority
Of people think there is an
Increase in obesity, this show
That they are aware of an increase.
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
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
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
