Obesity rates in the United States have more than doubled since the 1960s, where one in eight men and women were estimated to be obese (Fryar et al. 2012). The prevalence of obesity has now jumped to more than one in three men and women in the United States (Ogden et al. 2014; Flegal et al. 2012). This rate has remained the same since 2003 and is seen for both men and women of all ages and in every racial or ethnic group (Ogden et al. 2013; Simon et al. , 2006). Obesity has become a public health problem today because it exacerbates three societal issues: physical health, mental health, and economic costs. To begin, obesity has been shown to have negative health effects throughout the entire body. It increases risk for cardiovascular disease, hypertension, type 2 diabetes, arthritis, and numerous types of cancer (NIH 1998; van Dam 2007). Indeed, it is projected that 5% to 15% of deaths in the United States every year is due to obesity (Steward et al. 2009). Along with increased health risks to the individual, obesity is linked to mental health issues including depression and poor self-esteem (Wardle and Cooke 2005). In
An estimated 97 million adults in the United States are overweight or obese (Klein 2000). “"Affecting one in five Americans – or more than 22 percent of the U.S. population – obesity is one of the most pervasive health problems in our nation right now," said George L. Blackburn, M.D., Ph.D., associate professor of surgery and associate director of the Division of Nutrition at Harvard Medical School/Beth Israel Deaconess Hospital, Boston, Massachusetts. "We need to implement steps to slow the progression of this national epidemic” (NAASO 1999). But the problem of obesity does not only affect the United States. "We now know that the growing prevalence of obesity is creating major health problems worldwide," said Dr. James O. Hill, president of the North American Association for the Study of Obesity (NAASO) and Professor of Pediatrics and Medicine at the University of Colorado Health Sciences Center. Obesity was once regarded as unique to Americans, but it is now seen as a global health risk affecting developing and underdeveloped countries (AOA 2000). Obesity is increasing at an epidemic rate in the United States - 1.3% a year for women over 20. Rates of obesity among minority populations, including African-Americans and Hispanic Americans are especially high (AOA 2000). There is also a marked increase in obesity among children.
Obesity is defined as a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduce life expectancy and/or increased health problems. “The problem of obesity is increasing in the United States. Understanding the impact of social inequalities on health has become a public health priority in the new millennium. Social, political, and economic factors now are acknowledged to be "fundamental" causes of disease that affect behavior, beliefs, and biology.” (Goodman, 2003) In the United States today, obesity has become an enormous problem. In the last 3 decades, the number of people overweight has increased dramatically. Obesity has not always been seen as a medical
During the past 20 years, there has been a substantial increase in obesity in the United States and rates remain high. More than one-third of U.S.
As per Healthy People 2020 most Americans do not consume healthy diets and are not physically active at levels needed to maintain proper health. As a result of these behaviors the nation has experienced a dramatic increase in obesity in the U.S with 1 in 3 adults (34.0%) and 1 and 6 children and adolescents (16.2%) are obese. In addition to grave health consequences of being overweight and obese. It significantly raises medical cost and causes a great burden on the U.S medical care delivery system ("Healthy People 2020," 2014, p. 1).
Obesity has been a life long struggle. While myself and fifty percent of adults in the United States are battling obesity, the psychological effects have become larger than the obesity itself. Not only are we forced to deal with the physical effects of being overweight, I, like others have had to overcome the psychological effects as well. Low self esteem has been a challenge and has ultimately fueled my bout with depression. Although obesity, low self esteem, and depression are three separate issues, they are all linked and are all relevant to not only me, but to millions of Americans.
“Obesity is a disease that affects more than one-third of the U.S adult population (approximately 78.6 million Americans). The number of Americans with obesity had steadily increase since 1960, a trend that has slowed down in recent years but show no sign of reversing”.
Obesity is becoming an increasingly significant health concern in the United States, nearly to the point of epidemic proportions. To be considered obese, one’s body weight must be at least 20% over their ideal body weight; unfortunately with this definition, over 30% of all Americans are obese. Alarmingly, approximately
Adult overweight and obesity have become a worldwide issue that has very dangerous consequences on health. World Health Organization defines obesity as the “epidemic of the 21st Century”. WHO reports show that 1.9 billion people with 18 years age and older are overweight, and 600 million of them are obese. In the United States, obesity is a serious problem today that results from overconsumption of high-fat food and sugary food with lack of exercise. The Centers for Diseases Control and Prevention reports show that the obesity rates are above 20 percent in all states. Overweight and obesity have become a major public health issue because of their high rates of mortality and morbidity. People who are considered overweight or obese are at increased
Obesity has become increasingly more prominent in American society. The Unites States has even been termed an overweight nation. Some twenty to thirty percent of American adults are now considered obese (Hwang 1999 and Hirsch et al 1997). With this in mind, Americans constantly look around themselves determining their weight status as well as that of those around them. While some Americans do fit the healthy category, others enter the underweight, overweight, and even obese categories, all of which can be unhealthy.
Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
Obesity, the condition of being severely overweight, is a serious issue in the United States that is gradually beginning to affect more and more citizens. In recent years, the number of Americans suffering from this chronic disease has significantly increased. Researchers have found that nearly one third of the U.S. population is considered overweight and, on average, three hundred thousand individuals die yearly as a result of obesity (Hollands et al. 2). When one participates in little to no physical activity and their diet consists mostly of high fat foods, chances are they will gain weight. If someone becomes obese, they may develop serious health related issues that, in some cases,
Obesity rates in the United States are alarming, with more than one-third of U.S. adults and 17% of children qualifying as obese with a Body Mass Index greater than 30.0 (Centers for Disease Control (CDC), 2015). Even more frightening is the growth rate of this crippling health epidemic; between 1980 and 2014, obesity has doubled for adults and tripled for children (CDC, 2015). The physical consequences of rising obesity rates in our country include an abundance of physical ailments including type-2 diabetes, cardiovascular disease, sleep apnea, arthritis, elevated cholesterol, and even some cancers. Additionally, obesity-related health care costs to our country are estimated at $147 billion annually, plus the costs of productivity lost at
There are more than one billion overweigh adults in the world with at least three hundred of these adults being obese. In North America, obesity has increasingly become one of the most important public health problems (Flegal, Graubard, Williamson, & Gail 2005). With cases of obesity increasing, there has also been more exportation of research being done into the topic. Moreover, social, psychological and biological factors are being investigated to determine aspects that may influence the onset of obesity. This paper will focus on two specific domains of the biopsychosocial model of health with a focus on psychological and social factors that affect obesity.
Obesity has become an epidemic in our over indulgent North American society. In addition to body image issues, obesity causes significant health issues. Society often views obesity to be a disease when it is actually a sign of a disorder, genetic or environmental. The percentage of our population that is growing overweight is increasing every year, and can become a very serious issue if it is not dealt with urgently. Problems relating to self-confidence, self-consciousness, and isolation can occur as a result.
Obesity also affects hiring, evaluations, expectations, and individual’s salaries (Judge & Cable, 2011; Pingitore, Dugoni, Tindale, & Spring, 1994; Shapiro, King, & Quinones, 2007), this produces its own set of issues for businesses, individuals, and society; it creates a multitude of issues for social psychologists, occupational therapists, and psychoanalytic counselors to work with.
