Obesity : Causes And Effects

Obesity is defined as an accumulation of excessive fat that impairs a person health or a body mass index (BMI) that greater than or equal 30 (WHO, 2012). Childhood obesity is a major public health epidemic in which the prevalence has doubled in children and quadrupled in adolescents in the United States over the past three decades with the highest prevalence in Blacks, Hispanics and Native American children and the number is

Obesity is when a person has excess body fat. It is calculated by dividing one’s weight by his or her height to get the body mass index (BMI=kg/m^2). This number is also used to screen for health problems that maybe be caused by certain weight categories. A BMI of 25-29.9 is considered to be overweight and over thirty is considered obese. A third of children are overweight (CDC, 2014). Obesity leads to significant physical and mental health consequences. Obese children are at risk for bone and joint problems, sleep apnea, type two diabetes, high cholesterol, coronary artery disease and hypertension (CDC, 2014).

According to the Centers for Disease Control and Prevention, obesity is defined as “having excess body fat.” A child who is diagnosed as obese has a Body Mass Index of at or above the 95th percentile. Obesity has become one of the largest growing epidemics in the United States. Childhood

Obesity is defined as having excess body fat. To be considered obese, you must have a BMI of 30 or higher. Your BMI, Body Mass Index, is a measure of body fat based on height and weight. While obesity can affect all ages, sexes and ethnic groups, compared with whites, African-Americans have 51% higher and Hispanics have 21% higher obesity rates (CDC, 2010). Along with that, it has been found that women with higher education are less likely to be obese compared to those with less education (Rodrigo, 2013). Also, obesity is affecting younger ages each year; childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years. It is said that one-in-three children are affected by excess body weight, which then carries into adulthood. According to the AACAP (American Academy of Child and Adolescent Psychiatry), if one parent is obese, there is a 50% chance their child will be obese and if both parents are obese their child has an 80% chance of being obese.

To start of with what is Obesity? In the Merriam-Webster dictionary “obesity” is defined as “a condition characterized by the excessive accumulation and storage of fat in the body.” In the article by Kathryn Faguy (2016) called “ Obesity in Children and Adolescents: Health Effects and Imagining Implications” it goes deeper in explaining how obesity is determine in youth. It explains that obesity for adolescents, and children are categorized by weight to determine and compares a child’s Body Mass Index known as “BMI” to other children who are the same age and sex. A child is considered to be “overweight” if the child’s BMI is in the range of the 85th and 94th

Obesity has been around for several thousands of years but hasn’t always been a serious epidemic. A higher amount of fat or stored energy used to mean a greater chance at surviving a famine, but those times are long gone in the industrialized world. As time has progressed, we’ve see an exponential growth in obesity rates despite our best efforts to slow it down. In order to contain and eventually decrease obesity rates, we would first need to know what fuels this powerful monster of the western culture. Has our problem been generated from an increase in inactivity, sugar consumption, fat consumption, other factors or a combination of them? A collection of studies have been observed to discover what the real main factor to obesity in

Childhood obesity is a condition that affects children in the United States. According to the Centers for Disease Control and Prevention (CDC) the rates of obesity in children have more than doubled in children in the past 30 years. There was increase of 18% from 1980 to 2012 in children 6 to 11 years of age, estimating that more than one third of children are overweight or obese. ("Childhood Obesity Facts," 2014) Obesity usually begins in children during the ages of 5 and 6. The most troublesome fact is that studies have shown that obese children between 10 and 13 have a predisposition of becoming an obese adult. ("Obesity in Children and Teens," 2011) Consequently, overweight teenagers have a 70 percent chance of becoming obese or overweight adults, and if at least one parent is obese the child’s predisposition rate increases to 80 percent. (Bishop et al., 2005)

It’s a scary feeling when climbing a simple flight of stairs only to reach the top and be completely out of breath. In America today this is the reality that many children face. Obesity has become an epidemic in our world, it has many contributing factors, affects learning abilities but there are preventive methods for it. Although little is being done about obesity, it's affecting the lives of many but mostly children and by a multitude of different factors.

Obesity basically means having too much body fat. Not being overweight for your height, having too much muscle, or water in your body. What exactly is obesity? “Obesity is a condition that is associated with having an excess of body fat, defined by genetic and environmental factors that are difficult to control when dieting. Obesity is classified as having a Body Mass Index (BMI) of 30 or greater. BMI is a tool used to measure obesity. Obesity increases your risk of developing related conditions such as diabetes, hypertension and sleep apnea, to name a few. Many individuals are affected by obesity and are not aware of it” (O.A.C, 2016). Causes of obesity vary from person to person, but most are from the same reasons. Taking in more calories than your body can burn leads to obesity because your body stores the unused calories as fat. Typical causes are eating too much food than your body can use, drinking too much alcohol, and not getting enough exercise. Many obese people who lose large amounts of weight and gain it back think it is their fault. They blame themselves for not having the willpower to keep the weight off. Many people regain more weight than they lost. Today, we know that biology is a big reason why some people cannot keep the weight off. Some people who live in the same place and eat the same foods become obese, while others do not. Our bodies have a complex system to help keep our

Obesity is known to produce a number of stress and inflammation responses in the body that lead to the activation of the inflammatory signalling molecules, Jun NH2-terminal kinase (JNK) and inhibitory kB kinase (IKK). Activation of these pathways plays a key part in the development of insulin resistance followed by progression to diabetes as they greatly affect inflammatory responses, insulin signalling, and lipid and glucose homeostatis (Nakamura et al. 2014). For example, activating the JNK pathway leads to serine phosphorylation of insulin receptor substrate (IRS) proteins which results in inhibited insulin signalling and thus insulin resistance. Double-stranded RNA-dependent protein kinase (PKR) has recently been shown to control the JNK and other major inflammatory pathways, to directly inhibit insulin signalling, to be activated by fatty acids as well as endoplasmic reticulum (ER) stress, and to be necessary for the activity of inflammasomes (Nakamura et al. 2010; Komiya et al. 2010; Lu et al. 2012). Moreover, PKR has been found to be highly activated in obese people as well as mice with genetically and diet-induced obesity, especially in adipose and hepatic tissues (Boden et al. 2008; Nakamura et al. 2010; Carvalho-Filho et al. 2012). Finally, recent studies have found that PKR knockout obese mice were protected against both IR and obesity-triggered inflammation and that administration of PKR inhibitors reduced JNK activation, reduced inflammation in adipose

         According to the American Heart Association, as of January of 2013, one in three children in America is overweight or obese. That is three times that of only fifty years ago. Although we all know some underlying causes for childhood obesity, I am focusing on three major causes. These are parents and the perpetuation of unhealthy eating and lifestyle habits, the over consumption of fast food, and lastly, children and their decreasing physical activity levels. These three main factors, lead to childhood obesity which in turn leads to further long term and immediate health risks as well as psychological problems. Some people argue that genetics plays the major role when discussing factors of childhood obesity however, my focus on the mentioned causes is because they are by far more manageable when compared to genetics.

Obesity refers to the condition of having an extra amount of body fat. Obesity is caused by eating too much and moving too little. When an individual’s amount of body fat becomes too high, they are at a greater risk of being affected with life changing diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, and others. This shows that people should become more physically active and attempt to make healthier choices because their life depends on the decisions, they make.

The everyday routines of life can and will be more difficult if encumbered with obesity.

The epidemic of obesity is a medical circumstance defined as excess weight in the form of fat which may impair health. (World Obesity Federation, 2012). Obesity can be calculated by BMI which is body mass index. Obesity means BMI greater than 30. (ibid). This essay will outline the causes and effects of obesity. Diet, lifestyle, toxic environment and the causes of obesity are physical, psychological and economic are impacts.

Obesity is a condition in which the over accumulation of adipose fat tissue causes the weight of a person to increase abnormally. Their weight exceeds by 20%, as a factor of their ideal body weight. According to recent analysis, statistics show that more than one third of the world’s population is targeted by obesity. Research shows that overweight and obesity kills more people than underweight. Obesity occurs greatly amongst adults who are 18 years or older. An estimated 600 million adults were obese out of the 1.9 billion that were overweight, around the world in 2014. One in three adults in Mexico, New Zealand and United States are obese, and one in four adults in Australia, Canada, Chile and Hungary are obese. In contrast, rates of obesity are much lower in Asian countries, where approximately 2-4% of adults have obesity. In countries such as Mexico and the United States, Latino and Africans have the highest rates of obesity amongst all the individuals. However, along with adults, statistics show that the rates for obesity are also high among children within and below the age of 5. As calculated in 2013, the number of children across the world that were either overweight or obese was 42 million. Since then, the rates have increased by 30% more in in low- and middle-income countries than in developed countries. Due to the fact that this condition continues at higher rates across the world, several organizations, such as the World Health Organization, are working with and
