Obesity and Overweight is Different

Minggu, 20 Februari 2011

Many people think that 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 in the category of obesity, but may be overweight. If it's different, what really sets it apart. 

Some people are surprised by the question. Many people think that overweight with obesity. Obesity was so overweight. 

The debate between the obese and overweight often occur between us. In many countries, this problem is often encountered. Although we think is not very important to understand it, if wrongly understood, we can either direction.

Most doctors of nutrition as well as Dr. Cindiawaty Pudjiadi, Sp.GK MARS, MS, understand the different obesity with overweight. When translated, obesity is more significant obesity. This is a stacked state of excess body fat, weight sehinaga someone far above normal.

Meanwhile, overweight is defined as "overweight." This is a state of excess body weight above the normal person, not far beyond the normal weight.

WHO (World Health Organization) also distinguishes these two things. Mentioned "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 resolve the 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). IMT obtained by dividing weight (kg) by square of height (meters). BMI values obtained are not dependent on age and gender.

Indeed, BMI has shortcomings because it can not be used in children who are still in its infancy. BMI also does not apply to pregnant women and people who are very muscular like an athlete.

In the WHO standards, restrictions on overweight and obesity are known to the cut off point (maximum value) as follows: if a 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 Singaporeans with a BMI of 27-28 have the same body fat white men with a BMI of 30.

In people of India, increase in BMI from 22 to 24 can increase the prevalence of DM becomes 2-fold, and this prevalence increased to 3-fold in people with a BMI of 28.

Someone could say overweight if his BMI equal to or greater than 23. Meanwhile, when her BMI reaches 25.0 to 29.9 kg/m2, the person has entered the stage of obesity I, on this point, called the obesity II.

Measure the waist 
Results BMI also needs to be combined with measurement of the amount of 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 stomach are at higher risk than fat in 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, says that measuring waist circumference (waist circumference, WC) and waist and hip ratio (waist-to-hip ratio-WHR) is often used as an indicator obesity. However, most studies mention toilet is better than WHR because it is associated with cardiovascular risk. Abdominal fat (free fatty acids) is very easy to poison the liver that causes the emergence of insulin resistance, hyperinsulinemia, and various other disorders.

Disease infestation More Vulnerable

What could follow if the constant weight too much? Many health problems will come overweight-related conditions, including:

* • Diabetes mellitus. More than 85 percent of people with type 2 diabetes overweight. Suspected of being overweight to make cells resistant to change so that the hormone insulin. As a result, blood sugar levels became high. 

* • Sleep apnea (stopping breathing during sleep). People who are obese may be there is excess fat around his neck, thus narrowing the flow of breath. Therefore, breathing becomes difficult, and snore, or stop breathing occurs. Piles of fat also triggers the production of inflammation-causing substances, and this condition be a risk factor sleep apnea. 

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

* • Bladder problems. Excess weight because of fat would lead to bladder stones. 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 having some of this, a waist circumference greater than 90 cm (men) and more than 80 cm (women), high triglycerides (> 150 mg / dL), low HDL (<50 mg / dl), hypertension, and high blood sugar levels. 

* • Coronary heart disease (CHD). The presence of metabolic syndrome, makes the risk of CHD and stroke higher. Inflammation of blood vessels that are often triggered by the deposition of fat is also a risk factor for CHD. 

* • 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. Not yet known for certain, but presumably because the fat cells release hormones that influence the growth of body cells, which leads to cancer.

The world was Fighting Obesity Obesity has been regarded as an epidemic, especially in developed countries like the U.S. and several countries in Europe. 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 the lady Michelle Obama is too spicy to combat obesity. He joined seeks to enable parents, children, teachers, and communities to better health care and fight obesity. Michelle inaugurated the program last February Let's Move, which calls on people to return to healthy eating and active fisik.Di UK, obesity or excess weight gain experienced by 1 in 4 children are also assessed as a time bomb, so the more the attention of the government. Born healthy food programs, also re-turn on the old habit of healthy such as walking to school, play outdoors instead of watching television, playing games, or hang out with the internet.

In Singapore, to be accepted in a favorite school, not only the necessary intelligence and ability of the economy. Children also should be in good health, one of which looks at normal weight. Obesity is also found in 1 in 5 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 are weaker and more sluggish than the condition 10 years ago.

To anticipate these conditions, in addition to swimming, dancing activities are also included in the curriculum in schools. In fact, different dances designed for elementary school students, junior high and senior high.

Are You Overweight?
To measure the excess weight or not, the best day that is based on the Body Mass Index (BMI) or body mass index (BMI). The formula BMI is weight (in kilograms) divided by height (in meters) square.
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 * • 25.1 to 30.0 overweight  
* • 30.1 to 40.0 obese
* • clinically obese> 40
