24、Definitions of Obesity A)How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage. B)The World Health Organization recommends using a form

25、ula that takes into account a person s height and weight. The “Body Mass Index“(BMI)is calculated by dividing the persons weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 2

26、9.9 is considered to be overweight, while a BMI of over 30 is considered to be obese. C)However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very differen

27、t fat distributions. Another shortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program(NCEP)in the USA and the International Diabetes Foundation(IDF

28、)are starting to define obesity in adults simply in terms of waist circumference. Health Effects of Obesity D)Over 2000 years ago, the Greek physician Hippocrates wrote that “persons who are naturally very fat are apt to die earlier than those who are slender“. This observation remains very true tod

29、ay. Obesity has a major impact on a person s physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2(“mature onset diabetes“)and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats,

30、 and reduces blood pressure. The association between obesity and coronary heart disease is also well-known. Cancer E)Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a

31、 result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for

32、 men. F)The link between breast cancer and nutritional status is thought to be due to the steroid hormones, oestrogen and progesterone, which are produced by the ovaries, and govern a womans menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the

33、higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resu

34、lting in lower predisposition to breast cancer. G)The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world! Aging H)Research published by St Thomas Hospital, London, UK in 2005 showed a correlation between body fat and aging, to

35、 the extent that being obese added 8.8 years to a womans biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a wo

36、mans biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men. I)The aging effect was determined by measuring the length of telomeres, tiny “caps“ on the ends of chromosomes, which help protect the DNA from the

37、 ageing process. Indeed, telomeres have been dubbed the “chromosomal clock“ because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the

38、 chromosome from falling apart. It is believed that excess body fat and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres. Dementia J)Recent research(2005)c

39、onducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher. K)Scie

40、ntists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information

41、 to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia. Other Problems L)The world-wide upsurge in obesity, particularly in children, is of major economic concern

42、, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional “palpation“ examination, the danger being greatest for those women who are overweight or obese a growing

43、proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency cae-sarean section. M)This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome(SARS)and ultimatel

44、y, even bigger than AIDS. 47 The predictive test will help people to change lifestyle, which will reduce their risk of contracting dementia. 48 Women from less affluent nations tend to have much less breast cancer. 49 Obesity would affect a person s emotional well-being. 50 Obese people in middle ag

45、e run an increased risk of dementia. 51 Obesity has something to do with cancer in the prostate gland for man. 52 A non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to her biological age. 53 Whether one is simply overweight or has passed into the obese stage can be ju

46、dged according to the height-weight table. 54 The excess body fat, like the chemicals present in tobacco smoke, can lead to inflammation. 55 “Body Mass Index“ is limited in defining a persons weight ideal, because it does not takes into account many variables such as age, gender and ethnic origin. 5

47、6 The world-wide upsurge in obesity, especially in children, will possibly drain economies. Section C 56 There are three kinds of goals: short-term, medium-range and long-term goals. Short-range goals are those that usually deal with current activities, which we can apply on a daily basis. Such goal

48、s can be achieved in a week or less, or two weeks, or possible months. It should be remembered that just as a building is no stronger than its foundation, our long-term goals cannot amount to very much without the achievement of solid short-term goals. Upon completing our short-term goals, we should

49、 date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bulk on the foundation of the short-range goals. They might deal with just one term of school or the entire school year, or they could even extend for several years. Any time you move a step at a time, you should never allow yourself to become discouraged or overwhelmed. As you complete each step, you will enforce the bel
