An Exploration of the causes and effects of obesity Essay

fleshiness is redundancy body prolific. It is usually define by body flowerpot index (BMI) which is individual(a)s weight unit (kg) divided by their squ ars of height (m) (Jebb, 2004 Eagle et al, 2004). At the same cartridge holder, BMI was classify into four conditions. Firstly, when the BMI less than 18.5 kg/is underweight. Secondly, 18.5 kg/to less than 25.0 kg/ pass away to convention weight. Thirdly, overweight is 25.0 kg/to less than 30.0 kg/. Finally, exceeding 30.0 kg/ is totally grave (Eagle et al, 2004). other(a) papers categorize more than(prenominal) circumstantial in the part of cogent, which sections cardinal parts, such as, Grade I fleshiness (30.0 kg/to less than 35.0 kg/), Grade II fleshiness (35.0 kg/to less than 40.0 kg/) , extreme fleshiness or Grade trio (40.0 kg/or more) (Borrell and Samuel, 2014). corpulency has been defined as an epidemic by the International Task Force on Obesity and World wellness Organization in the 21st pennyury (Jim nez, 2011). For example, 65 per cent adults and 15 per cent children ar overweight in the States, and this data has non a decreasing trend (Jimnez, 2011).In recent long time, change magnitude corpulency problems pitch emerged in developed countries and even in nigh city centers in developing countries (Jimnez, 2011). According to Rosins investigation (cited in Tomer, 2011), incidences of fleshiness in the united States are high and impart been dramatically increasing over the past thirty familys, although in that respect are roughly beauty trends recently (Rosin in Tomer, 2011). For instance, the percentage of the obese population in the States rose twice from near 13.95 per cent (in 1976) to 29.57 per cent (in 2000), and this figure is continuing to grow (ibid). However, judge of corpulency are non nevertheless in America it is growing in all of the world even in Japan which has maven of the lowest order in the world (Bleich et al in Tomer, 2011 Delpeuch et al in Tomer, 2011).This essay consists of four sections, including introduction, effects of corpulency, causes of corpulency and conclusion. It will focus on the effects and causes of obesity. On the one hand, it analyses that dickens aspects of negative impacts which are demolition rate and continuing conditions are ca employ by obesity. On the other hand, this article discusses the interlinking reasons of obesity, which are classified as the ingrained instruments and acquired movers respectively.Effects of obesityNowadays, increasingly, slew suck in been focused on obesity bringing to serious impacts of health. The effects of obesity cigarette be classified into two parts. One is the family of obesity and d fertiliseh rates a nonher is the relationship of obesity and inveterate conditions (Tomer, 2011). It is claimed that the mortality rate risk and wrong d annihilatehs are influenced by obesity epidemic amid American adults (Borrell and Samuel, 2014). Some data indi cates 300,000 immature deaths per year are connected with obesity in America (Tomer, 2011). Furthermore, in that respect is a school of thought that obesity is a principal(prenominal) risk factor for some another(prenominal) chronic conditions. There are k without delay as the Western complaint including type 2 diabetes, cardiovascular distemper (CVD), certain types of crabby person, hypertension and hypercholesterolemia (Rosin in Tomer, 2011). Let us now discuss two aspects of negative impacts.The relationship of Death Rate and ObesityThere is a possibility that obesity will decrease individuals livelihoodspan by 3 to 13 years on average (Jimnez, 2011). Mortality world power be greater and greater when the obesity phenomenon becomes serious in the future. all over the past five decades, obesity has been relate to morbidity or all-cause mortality which means death rates caused by diseases, except for taking dugs and suicide, in the United States and elsewhere (Borrell a nd Samuel, 2014). Firstly, compared with a normal weight individual, obese adults convey at least 20 per cent high rate of dying for all-cause (Borrell and Samuel, 2014). Further, an obese individual who is Grade I obesity will die earlier at least 1.6 years than a normal-weight individual considering all causes (ibid). At the same time, this figure for Grades II and III obesity person are 3.7 years (ibid).Secondly, base on Borrells explore data, when individual who is overweight and obese (regardless of the grade) get the CVD disease, it can be found out that these individuals dying rate will be significantly higher than individuals who have normal weight (Borrell and Samuel, 2014). After examine individuals who were different race and have different education backgrounds, the research acquired it one root that obese individuals might have a shorter life than normal-weight individuals for CVD-specific mortality and the same phenomenon could exist in different ages concourse(i bid).In addition, the weighty situations were the worst in obese adults whose ages are between 45 and 64 for all-cause and CVD-specific mortality (Borrell and Samuel, 2014). It means that Grades II and III obese adults aged 45 to 64 years have significantly higher death rates than large number who have normal weight. These higher death rates genius to among Grades II and III obese adults (45 to 64 years old) early death by at least 7 years (ibid). Through a great many prospective studies, it is widely accepted that obesity contributes to premature death. Apart from, obesity has other disadvantages to individuals.The relationship of Chronic ConditionsObesity might raise both(prenominal) diseases hazard and the biggest main risk is cardiovascular disease (Jebb, 2004). There are these who avow that, in public health terms, the largest rouse of disease is morbidity which is related with obesity and almost every electronic organ of human body is caused by obesity (Jebb, 2004). Jeb b (2004) states that It effects include metabolic syndrome (type 2 diabetes, hypertension and hyperlipidemia), and mechanical disorders (e.g. osteoarthritis, respiratory problems, sleep apnoea) and psychosocial disorders (Jebb, 2004). Other learner has a similar view that it is a significant problem that obesity is not only one of the endocrine-metabolic conditions but also is a number one of a series of diseases including type 2 diabetes mellitus, cardiovascular diseases, metabolic syndrome and many types of cancer in public health (Jimnez, 2011). Let us exposit that those relationships between obesity and the following diseases.Firstly, on that point is an extremely close relationship of type 2 diabetes and obesity. Diabetes belongs to metabolic syndrome, which causes the factors of atherosclerotic disease (Jebb, 2004). Further, the development and tartness of this charitable of disease is depending on weight increase (ibid), thus obesity is an important element factor. Fo r example, women whose BMI is 25 kg/ lead to the probability of diabetes is safe five-fold, if the BMI is over 35 kg/, the probability will increased to more than 40-fold (Jebb, 2004). Furthermore, the probability of diabetes still depends on different bodyshapes, such as, apple-shaped, pear-shaped, if women have a similar BMI. Jebb found apple-shaped women who have a large shank are higher diabetes risk than pear-shaped women who have excess fat on the thighs and hips (Jebb, 2004).Secondly, cardiovascular disease is also linked with obesity or weight increase. The Nurses wellness Study suggests that BMI is associated with cardiovascular disease (Jebb, 2004). Compared with the risk of CVD at BMI less than 21.5, the risk rose from BMI 22-23 and doubled at 25-28.9 and more than three times higher when the BMI reached at above 29 (ibid).Thirdly, the recent year have a growing recognition which is the relationship between obesity and increased risk of most types of cancer, with the ex ception of lung cancer, postmenopausal breast cancer, colon and kidney cancer (Jebb, 2004). At the same time, it is estimated to ascribe 20 per cent of cancer deaths in women to obesity (ibid). It seems that the link between cancer and obesity is confirmed.To correspond up, obesity is a serious global problem. To some terminus, it became a cause of death to fake human beings die prematurely. In recent years, people have begun to pay close attention to this topic. But what caused the obesity is the rudimentary point, which is worth us to explore the next section will analyze some important factors that lead to obesity.Causes of obesityThe causes of obesity are extremely complex. A huge number of research indicate that the reason of obesity is not a single result. People are obese because of the complex interaction between genes and the unique personal habits (Eagle et al, 2004 Jimnez, 2011 Tomer, 2011). Firstly, genes are not only significant factor for obesity, but the pur lieu also plays an important role (ibid). At the same time, genes will be changed with parental unique life style and their adjoin (Eagle et al 2004 Jimnez, 2011). Secondly, the unique personal habits involve numerous aspects, such as, diet, election habit, sedentary lifestyle and other social factors (Tomer, 2011). It seems that the causes of obesity are complex and constantly changing. To sum up, these reasons are divided into two major categories, essential and acquired factors. This section will detail how two kinds of factors can make individuals obese. inborn factorsThere is no doubt that genes are one of the causes for obesity. Nowadays, sufficiently self-colored scientific evidence provides that genes are involved in the development of obesity (Jimnez, 2011). It is determined that individuals metabolism, detoxification and production of hormones could increase their weight and make them obese (Tomer, 2011). For instance, some small parts of obese individuals owes to gene s which lead to some clinical syndrome. Obesitys monogenic reasons include mutations in the leptin gene and its receptor, or the melanocortin system. Other genetic syndromes are a common element of the phenotype. However, these occupy only small parts (Jebb, 2004). At the same time, heritability studies indicate that genetic factor is only influenced approximately a third of the variance of BMI (ibid).Therefore, it is claimed that genes are bonnie potential inducers for obesity (Jimnez, 2011). On the other hand, even some scholars maintain that obesity is the result mixed up with certain genes and the environment. Genetic changes expose a new trend that obesity is a result of the interaction between genes and environment (Jimnez, 2011). It means that the new gene will be decided jointly by the previous generation of genes and environments. Furthermore, a mass of other candidate genes have been associated with obesity. For example, feed preferences or exercise habits (Jebb, 2004). Acquired factorsCompared with congenital factors, acquired factors are more influenced for obesity. It is reflected in the peoples diet, behavior patterns and many other aspects (Eagle et al, 2004 Jimnez, 2011 Tomer, 2011). Jimnezs view is that due to a long time zippos accumulation which is postal code inlet exceeds people inevitably, there are some obese people. Two crucial behaviors are food intake and taking exercise resulted in obesity (Jimnez, 2011). Hyman (cited in Tomer, 2011) states that there are three dietary reasons producing obesity, including diet high in refined, impact carbohydrates, diet high in bad fats and diet low in fiber (Hyman in Tomer, 2011).However, Brownel (cited in Tomer, 2011) concluded that powerful forces of society and shade are the root of the obesity problem, because it can promoteindividuals selecting high energy diet and a sedentary lifestyle (Brownel et al in Tomer, 2011). Over the past three decades, the obesity issue was aggravated by this kind of environment (Brownel et al in Tomer, 2011). It is worth noting, these effects will not make everyone change their eating habits it depends on different people. Apart from genes, if mortal understands nutrition very well, they may escape the effect of environment. Nevertheless, unfortunately a great many people are vulnerable to the toxic environment impact (Brownel et al in Tomer, 2011).This next section will by chance explain the acquired factors of obesity, including eating habits, less activity and watching advertisements on television. owe to some poor eating habits, there were so many obese people (McLannahan and Clifton, 2008 p28). In the first place, different foods provide different extent energy, so that intake energy more than their need lead to obesity. For example, when individuals eat more than their need in their daily life, they will become fatter (McLannahan and Clifton, 2008 p29-31). It demonstrates that excess foods intake caused excess body weight (Mc Lannahan and Clifton, 2008 p29). In the second place, energy-dense diet is an important reason for make people obese. Energy-dense diets are high in fat, high in added sugars and low in growth and vegetables and this kind of diet could enhance the probability of obesity (Jebb, 2004).Fast foods are typical energy dense diets, and these are acknowledged to be a risk factor for obesity (Niemeier et al in Musaiger et al, 2014). Musaigers research showed that as a result of the high uptake of fast food, there was an increase trend about obesity (Musaiger et al, 2014). At the same time, a report was carried out by Gortmaker (cited in Musaiger et al, 2014), a high consumption of soft drinks was proved to be a reason for obesity.It is concluded that honeylike beverages are less satiating than solid food containing similar calorie set, therefore it contributes to acquire more energy (Gortmaker et al in Musaiger et al, 2014). In addition, there is a school of thought that eating more gro wth and vegetables are beneficial to decrease the probability of obesity (Musaiger et al, 2014). For instance, in the United States, 12-year old boys and 11-year-old girls consumed any fruits and vegetable occupied 56.1 per cent and 65.5 per cent respectively (Eagle et al, 2004). It may be explained that nearly half children do noteat any fruits and vegetable, and it boosts the number of obese children.Another important reason is lose of activity. Nowadays, modern people living in developed societies do not take more exercise than their ancestor (McLannahan and Clifton, 2008 p28). It is possible lead to obesity. Hyman (cited in Tomer, 2011) provides that a sedentary pattern can make weight gaining, through the lower metabolic rates (Hyman in Tomer, 2011). Moreover, some evidence indicates that the ken of the innate appetite control system can be reinforced by high levels of physical activity. In the mean time, it is easier to automatically make energy intake and energy needs bala nce (Jebb, 2004). This is a key issue that increases in obesity can not be plainly attributed to over-eating or inadequate activity, rather it represents a failure of the homeostatic mechanisms to but match energy intake to the bodys energy needs (Jebb, 2004).Furthermore, exercises levels are also important. People whether willing to do exercise is a main factor of energy needs (Jebb, 2004). For example, if a person who is a white-collar worker has a sedentary life, thrust a car commuting and not seeking leisure activity, their radical metabolic rate may be used just 30 per cent (Jebb, 2004). On the contrary, a generally combat-ready adult may expend about 60 per cent and a particular active sportsman can consume double her or him basal energy needs (Jebb, 2004). It can be seen that doing more activity contributes to consume more energy, particularly helping to maintain insulin sensitivity and reduce the risk of obesity.Furthermore, in the recent year, people spend more time on p rofit and watching television. Therefore, high-tech environment brings some influences to make people obese. The enthalpy J Kaiser Family Foundation indicates that adverts on television have effects on childhood obesity levels (Musaiger et al, 2014). At the same time, according to the American psychological Associations report, children less than 8 year olds do not distinguish the difference between adverts and reality (Musaiger et al, 2014). Through displaying some advertisements which some stars eating delicious foods makes a condition reflection, so that people who watches advertisements may eat more foods, and it causes an increase of intake energy, especially if people repeatedly watches these advertisements on television (Eagle et al, 2004).Actually, is utilizes the changeless relationship of stimulus and response in humans brain, according to Classical Conditioning theory (Eagle et al, 2004). When people watches television, it equivalently irritate people awareness that need eating snack or meals. Thus watching television is a way to cause intake more energy and make people obesity. Further, advertisements on television not only boost people eating but also have negative impacts on food choices of viewers. To some extent, it caused people preferring to choose higher fat and higher energy foods (Eagle et al, 2004). To sum up, watching television leads to people become obesity.As discussed above, there is a dramatic rise about obesity in many countries nowadays, due to the complex interaction of a variety of reasons, divided to congenital causes and acquired factors (Wright, 2012). Moreover, obesity has many negative impacts on human health. It represents in higher death rate and many chronic conditions. The purpose of this essay is make people understand that these diseases have produced in earnest harm to peoples health, and through explaining causes of obesity make people improve obesity problem. To be specific, the causes which lead to obesity are c urious complex, divided into congenital and acquired factors. There is no doubt that the congenital factor is genes result in obesitys development. Furthermore, the acquired factors involved many aspects, including diet, life behavior patterns and high-tech environment.This essay particularly has explained that three factors, such as eating habits, physical activity and watching advertisements on television, resulted in obesity. On the other hand, obesity is not only endocrine-metabolic disease, but also it is many other diseases start. For instance, some serious risks which are the premature death and morbidity of chronic conditions are caused by obesity. Firstly, about premature death, this essay used some data which compared different lifespan of different extent obese people and normal weight people, particularly middle aged and elder people are particularly serious. In addition, in the part of chronic disease, this essay has analysed the type 2 diabetes, cardiovascular disease s and some types of cancer were produced by obesity. To sum up, obesity is a global problem. As a result of many complex reasons, there are increasing people became obesity. At the same time, obesity boosts rate of premature death andmorbidity of chronic conditions.ReferencesBorrell, L. and Samuel, L.
