Obesity & Overweight Apparently Unlike

Minggu, 08 Agustus 2010


Many people think obesity and overweight are the same. Quite often, people say "obese" to someone who looks overweight. In fact, if his body mass index was measured, not yet entered the category of obesity, but maybe overweight. If it's different, what exactly is the difference.

Some people were surprised by the question. Many are considered overweight with obesity. Obesity is yes being overweight (overweight).
The debate between obesity and overweight often occur between us. In many countries, these problems were often encountered. Although we assume is not very important to understand it, if wrongly understood, we can also mislead.
Most doctors like Dr. nutrition. Cindiawaty Pudjiadi, Sp.GK MARS, MS, understand the different obesity with overweight. When translated, means more to obesity overweight. This is a state of excess body fat deposition, weight sehinaga someone far above normal.
Meanwhile, more overweight is defined as "overweight." This is a state of excess body weight above the normal person, not far beyond the normal weight.
World Health Organization, WHO (World Health Organization) also distinguishes these two items. Stated "The fundamental cause of obesity and overweight is an energy imbalance Between Calories consumed on one hand, and Calories expenditures on the other hand."
So obviously, this statement is completed controversy. Obesity is different from overweight.
To avoid confusion, the WHO set a measuring tool that can be used by doctors or nutritionists around the world, BMI (body mass index) or body mass index (BMI). BMI is obtained by dividing weight (kg) by square of height (meters). BMI value obtained does not depend on age and gender.
Indeed, BMI has the disadvantage because they can not be used in children who are still growing. BMI also does not apply to pregnant women and very muscular people such as athletes.
In the WHO standards, restrictions on overweight and obesity is known to cut off point (maximum value) as follows: if the same person with a BMI from 25.1 to 30, meaning he was included in the overweight group. If the BMI of a person over 30, meaning that the person is entered in the obese group.
The experts are trying to find the classification of BMI for Asian population. Results of research in Singapore shows that people with BMI 27-28 Singapore has the same body fat white men with a BMI 30.
In people of India, increasing BMI from 22 to 24 can increase the prevalence of DM to be two-fold, and this prevalence rises to three-fold in people with BMI 28.
Someone could say overweight if his BMI equal to or greater than 23. Meanwhile, when her BMI has reached 25.0 to 29.9 kg/m2, the person has entered the stage of obesity I, the above points, called obesity II.
Measure the waist ungkar
BMI results also need to be combined with measurement of total fat mass in the abdomen. You do this by measuring waist circumference. Someone who has a waist circumference greater than 90 cm (for men) and 80 cm (for women) have to be careful with the risk of obesity.
Measurement of the amount of abdominal fat mass is important because fat around the abdomen higher risk than fat on the thighs or other body parts.
Prof. DR. Dr. Askandar Tjokroprawiro, Sp.PD-KEMD, from the Diabetes and Nutrition Center, Airlangga University School of Medicine, suggests that measurement of waist circumference (waist circumference, WC) and waist and hip ratio (waist-to-hip ratio-WHR) was often used as an indicator obesity. However, most studies mention the toilets are better than WHR because it is associated with cardiovascular risk. Belly fat (free fatty acids) is very easy to poison the liver that causes the emergence of insulin resistance, hyperinsulinemia, and various other disorders.
Vulnerable increasingly inhibited disease
What could follow if the weight keeps it too much? Many health problems will come regarding the condition of overweight, including:
* • Diabetes mellitus. More than 85 percent of people with type 2 diabetes experienced overweight. Suspected of being overweight makes the cells resistant to change so that the hormone insulin. As a result, blood sugar levels are high.

* • Sleep apnea (stopping breathing during sleep). People who have excess fat could be fat around the neck, thus narrowing the flow of breath. Therefore, breathing becomes difficult, and snore, or stop breathing occurs. The stack also trigger the production of fatty substances that cause inflammation, and this condition becomes a risk factor sleep apnea.

* • Osteoarthritis. Body fat will give extra pressure on kartilase and joints, so that could be quickly damaged. Fat deposits will also trigger inflammation. Inflammation of the joints is a risk factor for osteoarthritis.

* • Bladder problems. Overweight due to fatty deposits will trigger a stone in the bladder. Overweight also have an enlarged bladder, so it can not work properly.

* • metabolic syndrome. Fat, especially in the abdominal area and lack of exercise are risk factors for this condition. Metabolic syndrome is said if someone is experiencing some of this, a waist circumference of more than 90 cm (men) and more than 80 cm (women), high triglycerides (> 150 mg / dL), low HDL (<50>
* • Cancer. Being overweight increases the risk of cancer, especially colon cancer, esophagus, and kidney. In women menopause is also associated with breast and cervical cancer. Exact cause is unknown, but presumably because the fat cells release hormones that affect the growth of body cells, which leads to cancer.

Any World Combat Obesity Obesity has been regarded as an epidemic, especially in developed countries like the U.S. and several European countries. According to Newsweek's online edition reports, a third of U.S. children are overweight and cost billions of dollars needed to cope with obesity-related diseases such as diabetes, heart disease and cancer.
That's why Michelle Obama was the mother country strives to combat obesity. He has taken part seeks to enable parents, children, teachers and communities to better health care and fight obesity. Michelle inaugurated last February Let's Move Program, which invites people to return to healthy eating and active fisik.Di UK, obesity or overweight who experienced one of four children was also considered as a time bomb, so the more the attention of government. Thus was born a healthy diet programs, as well switch back to the old habit of healthful such as walking to school, playing outdoors instead of watching television, playing games, or interact with the Internet.
In Singapore, to be acceptable in school, not only the necessary intelligence and ability to be economically viable. Children must also be in a healthy condition that one of them looked at a normal weight. Obesity is also found in one of five children in China. Since the presence of U.S. fast-food restaurant and a lack of motion, this time the condition of children in China is weaker and slower compared with the condition 10 years ago.
To anticipate these conditions, in addition to swimming, dancing activities are also incorporated into the curriculum in schools. In fact, different dances designed for elementary school students, junior secondary and upper secondary.
Are You Overweight?
To measure the excess weight or not, the most precise currently based at the Body Mass Index (BMI) or body mass index (BMI). The formula BMI is weight (in kilograms) divided by height (in meters) squared.
Example: If the weight of 75 kg and height 170 cm.

BMI = 75: (1.7 X 1.7) = 75: 2.89 = 26 (overweight).

Category results of IMT measurement:
* • severe underweight if her BMI from 14.0 to 16.0

* • underweight from 17.0 to 18.4

* • Normal weight 18.5 to 25.0

* • overweight 25.1 to 30.0

* • 30.1 to 40.0 obese

* • clinically obese> 40
