Effects of Sedentary Lifestyle on Obesity

Effects of Sedentary Lifestyle on ObesityIntroductionCurrently, corpulency and operose is a main global health problem plaguing almost the whole planet. Studies show that in 2005 1.6 billion magnanimouss were overweight and 400 million adults were obese. As it is portrayed, obesity and overweight is a problem of the contemporary societies that dissolvenot be confronted. According to a recent study of the World Health Organisation, it is predicted that there will be 2.3 billion overweight adults by 2015 in the world and more than 700 million of them will be obese. Also it is definitive to realise that obesity and overweigh are contemporary problems of the societies since statistics referring to these problems did not exist 60 years ago. Therefore, it is clear that obesity and overweight apart from genetic predisposition and psychological disorders might derive as rise from the modern sedentary lifestyle that is highly affected by the recent technological development and from poor nutrition as there is an increase in convenience food. However in order to understand the extent and significance of the problem it is important to define and analyse overweight and obesity.Obesity can be defined as a medical condition in which body round has accumulated to the extent that it has a negative effect on health. A healthy body requires a minimum amount offatfor the proper functioning of thehormonal,reproductive, andimmunesystems, asthermal insulation, asshock absorptionfor untoughened areas, and asenergyfor future use. But the accumulation of too much storage fat can impair movement and flexibility, can alter the display of the body and cause health problems.Obesity increases the likelihood ofvarious diseases like disembodied spirit disease,type 2 diabetes,breathing difficulties during sleep (pulmonary diseases), hypertension, certain types ofmalignant neoplastic disease, andosteoarthritis. In particular, cancer of the colon as well as prostate in men and cance r in breasts, ovaries and cervix in women have been found to be tie in to obesity. Furthermore, hypertension has been found to be related CHD and strokes. As a result, obesity has been found to reducelife prevision and be one of the leadingpreventable causes of deathworldwide. Investigators have estimated that if everybody had the optimal body mass there would be 3 years added to life expectancy, 25 percent less coronary heart disease and 35 percent less congestive heart failure and brain infection.Overweight is generally defined as having morebody fatthan is optimallyhealthy, without reaching the body fat value for obesity. The generally accepted view is that being overweight causes similar health problems to obesity, but to a fry degree. It is estimated that the risk of death increases by 20 to 40 percent among overweight people and that being overweight at age 40 reduces life expectancy by three years.Being overweight or obese has been identified also as a cause ofcancer. Psyc hological well-being is also at risk in the overweight individual due to socialdiscrimination. However, children under the age of eight are normally not affected.The prevalence of obesity and overweight is strongly related to age. The 16 to 24 years age group (for both men and women) is substantially less at risk ofbecoming obese than older age groups. Those aged between 25 and 34 have the second lowest rates of obesity and overweight. Middle aged people are those who are in the most risky position of becoming obese or overweight.In order to further understand obesity and overweight it is important to analyse the methods utilize in order to classify and tell the degree to which a person is overweight or obese. The most popular method used is that ofthe Body Mass index(BMI), orQuetelet index. The Body Mass index is a statistical measure of body weight based on a persons weight and height. Though it does not actually measure thepercentage of body fat, it is used to estimate a healthy body weightbased on a persons height. Due to its ease of measurement and calculation, it is the most popular diagnostic tool to identify weight problems within a population, usually to classify adult underweight, overweight and obesity.Body Mass Index is found by dividing the body mass in kilograms by the square of height in meters.This technique can also act as a health since it appears to provide relative results concerning the degree of risk associated with overweight or obesity.Mortality and morbidity start increase at high rates at a BMI of more than 25. Therefore the desired levels of BMI are those below 25. Below there is a table of the BMI potpourri according to the World Health Organisation confirming what was previously stated.ClassificationBMI(kg/m2)Underweight
