What is Obesity
Obesity is a chronic illness that comes with multiple complications, characterized by excessive accumulation of fat within a magnitude such that compromises the health, among the most common complications is diabetes mellitus, hypertension, lipid metabolism, musculoskeletal changes and the increased incidence of some types of carcinoma and mortality rates.
Obesity is the result of ingesting more energy than necessary. There is no doubt that this excessive consumption can start time phased very remote, in which the cultural influences and family habits have a key role. So we say that obesity has multiple character factors, such as genetic, psychosocial agents, cultural, nutritional-metabolic and endocrine. Obesity therefore is generated by interaction between genetic factors and cultural, as well as families.
There is a clear trend among members of the same family have a body mass index (BMI) similar. There are several scientific publications that have demonstrated a correlation between BMI of fathers and sons, suggesting that probably both genes as a shared family environment, contribute to the development of obesity.
Obesity in childhood
According to the Child Psychiatry Manual, 1983, a child is considered obese when exceeds 15 average weight corresponding to his age, since excess weight corresponds to the accumulation of lipids, which can be measured by the thickness of the fold of skin. However, it is not easy to establish parameters which define exactly the boundary between normal weight, overweight and obesity.
Influence of genetic heritage
The biological variety of the people regarding the storage of excess energy intake is too large. This fact is closely related to the individual susceptibility and their genetic heritage.
Accordingly, some people will never have overweight or obese, others may increase in weight as they increase in age, and yet others can start weight increase since childhood and keep it in later ages.
Therefore, believe doctors and experts from various areas of the participants, it is possible to reduce the Consensus influence of genetic susceptibility to changes in culture by making food family and also of the population as a whole, through education and prevention programs.
Psychological factors have an influence on Obesity
Also takes into account the influence of emotional disorders and psychological factors on the prevalence of obesity. the psychic mechanisms of oral fixation, oral regression and overestimating the value of foods are of great impact on the way people develop eating habits. It is common, for example, that a past history of body image depression and poor appetite control primitive conditioning leads to eating disorders such as bulimia, anorexia and obesity.
However, in addition to the genetic, psychological and family influences, the most important factors for the increase in the incidence of obesity was added in the sedentary life habits and consumption of processed foods with the highest content of fats, carbohydrates and less amount of fiber.
