Obesity in children. Statistics and causes of

The magnitude of the problem and the spread of dilemma
Beginning we would like to say how much the problem of weight gain in children, whether in Saudi Arabia or in the Arab world around us. The the careful to attribute the prevalence of overweight in children in Saudi Arabia realizes that the size of the problem is increasing steadily, and through a quick review of what has been published over the past years, we find that one of the first statistical studies of weight gain in children due to a study published in 1996 AD and included about nine thousand children showed that the proportion of obese children about fifteen per cent and that of overweight about a ten per cent. However, with the progress of years, we find that these ratios increase both the level of overweight or obesity rates, In a study published in the Eastern Province of Saudi Arabia made it clear that almost nineteen percent of children are overweight and that twenty-three percent of them suffer from Obesity and about fifty per cent of adolescents suffer from weights high and approach the upper limit natural study was released, which included more than seven thousand children in 2010 AD, has attributed some local studies that to the lack of physical activity, the study showed local printed 2004 AD to inactivity and lack of exercise any athletic activity is a way of forty to 99 per cent of children and it seems that the situation is much worse these days with the proliferation of electronic entertainment and television, among others. Do not stand ratios overweight among children, but only continue the problem until old age, studies show in Saudi Arabia, the rate of weight people overweight increasingly growing old and that is covariant The peak in the fifth decade of life has reached rate of obesity in these studies to 30 % for females was lucky it compared to males.

Definition of overweight in children:
There are terms concerning weight increase and are overweight, obesity and each with a different definition weigh excess is to be BMI of more than 25%, while obesity is defined to be the rate of more than 30% of any that obesity is the highest degree of overweight. The BMI is the result of dividing the weight Balcleogram on the amount of height in meters. Specialists depends on previous measurements to define obesity and overweight and there are also other ways as knowledge and weight compared curves allocated to it and the volume density of the skin and others. Of various scales.
Causes of obesity and weight gain in children:
Unsatisfactory reasons:
We must know that most of the causes of obesity is unsatisfactory than usual and known to the general public, and be due to excessive eating and lack of exercise. It may be the evolution of modern life and modern techniques that facilitated the individual meet all their needs in life a major cause of weight gain as they سلبته freedom of movement, bringing the elevator substitute for the stairs, and the car substitute for the feet, and control devices television has become the main driver for the operation of TV channels. We must realize that obesity caused by the behavior of the sinner when most children in the present day and it is no longer limited to watching TV were several satellite channels and spread electronic games not to mention Internet navigation and so on, which made small by the large captive in front of him, and the nutritionally Fujbat children usually lack the necessary nutrients and replaced in most fast food empty food containing sugars and carbonated water and others.

Satisfactory reasons:

The pathologies of obesity are less frequent cause diseases and endocrine hormones such as lack of secretion of growth hormone, thyroid hormone, parathyroid or increase secretion of adrenal gland or pituitary gland diseases and brain tumors and hypothalamus and there are some syndromes causing obesity and accompanied by some other diseases. In General, are these reasons usually are associated with a limited increase in weight and not excessive.

Genetic reasons:

The role of heredity in obesity among children, the child's mother--obesity is more susceptible to injury and there are many pathogens for obesity be a genetic factor involved in this valtwam fat be brothers to obesity more than other. Confirming the role of heredity as a cause of obesity. There is a rare genetic disease and may cause weight gain, such as:

Jane legacy called leptin and the gene responsible for the composition of the protein leptin, lack this gene cause when rats eating and not hyper in response to insulin and leptin of rats reverses all the qualities of this disease and leptin is produced in fat cells and intestinal tract and the placenta. Wallbetin sends signals to the brain about the amount of fat stored in the body. These and other observations to link leptin increased obesity and obesity because of a lack of leptin was found in two or more. And treatment of members of these two families in physiological doses of leptin decline in food consumption and a significant loss in weight and fat mass. As we stated earlier, these genetic causes are for less than the causes of overweight in children. The second reason gene genetic is a bug in the leptin receptor gene and gene leptin and receptors are present in humans and is not the cure to date. There are a large number of other relevant genes and weight gain and there are also a number of syndromes causing weight gain such as Prader Willi syndrome, syndrome Laurence-Moon Biddle and others.

Fix the problem:

To fix the problem is to prevent it so that drug therapy or surgery has no place in obesity especially those affecting children. Health education plays an important role, not only the family but also to schools and health centres and society as a whole. We must educate children and parents damaged obesity as a cause of heart disease, hypertension, diabetes, arthritis and other diseases in schools, health centres, etc., and also focus on the importance of a healthy balanced diet and exercise for children who have a genetic predisposition to it. Either living with obesity of children, sports training programmes must be set up with food to help them lose weight while providing psycho-social support.
