To watch television linked to an increased risk of type 2 diabetes, heart disease and death

In an analysis data from several studies, watching TV for 2 or 3 hours per day or more was associated with a risk of type 2 diabetes, fatal and non-fatal cardiovascular disease and death causes, a study in JAMA on 15 June says.

Watching television (TV) is the daily activity most frequently reported in work and sleep in many populations around the world. The United States, the average number of hours of TV reported recently that 5 hours. "More than modify energy expenditure to spend the time devoted to physical activity, viewing TV is associated with unhealthy food (for example, a higher intake of fried foods, meats and drinks sweetened with sugar) and low consumption of fruit, vegetables and whole grains in children and adults," according to the information of the substance in the article. "Physical inactivity, various dietary factors and smoking are risk factors independently established for type 2 diabetes, cardiovascular disease and mortality causes". Because watching television is the most common and widespread sedentary behavior, there is great interest to quantify its independent association with results for health. "However, systematic and quantitative published studies assessment is not available."

Anders Grontved, m.p.h., master of the University of South Denmark, Odense and Frank b. Hu, MD, PhD, Harvard School of public health, Boston, an analysis of the purpose of summarizing the data from the studies of prospective cohort published on the association between the display of the TV and the incidence of fatal or nonfatal cardiovascular maladies type 2 diabetes and all cause mortality. Researchers have carried out a search in the medical literatures for relevant studies in 1970 to March 2011 and identified eight studies meeting their inclusion criteria in the analysis.

Type 2 diabetes (4 studies), the total number of persons was 175,938 with 6,428 cases of incidents during an average follow-up of 8.5 years. For cardiovascular disease fatal or nonfatal (4 studies), the total number of persons was 34,253 with 1 052 cases of incidents during an average follow-up of 10.4 years; for mortality all causes (three studies), the total number of persons was 26,509 1,879 death during an average follow-up of 6.8 years.

An analysis of the data indicated that 2 hours of television seeing time per day was associated with an increased risk of 20% for type 2 diabetes; 15 percent increased risk of fatal cardiovascular disease or non-fatal; and more than 13% of all causes of mortality risk. "While time spent associating watching TV and the risk of cardiovascular disease and type 2 diabetes are linear, the risk of mortality of cause all appear to increase the duration of viewing TV for more than 3 hours a day,"the authors write.

Based on the rate of frequency in the United States, the estimation of the risk difference researchers all (cases per 100,000 persons per year) for 2 hours of TV per day was 176 for diabetes type 2, 38 fatal cardiovascular disease and 104 for all causes of mortality.

"It is biologically plausible that longing to see that TV is associated with type 2 diabetes, cardiovascular disease and mortality causes." Many studies have reported TV partnerships with biological risk factors of these results, including obesity, levels of unwanted lipids and cardiovascular risk in a cluster. However, some studies step reported these associations. On the other hand, the associations of sedentary behaviour similar to listen to the TV (e.g., sitting at work or during driving) with type 2 diabetes, fatal or nonfatal cardiovascular disease and all-cause mortality have been reported in cohort studies, "the authors write.

"Further research is warranted to quantify the Ombudsman of the influence of diet and physical inactivity." "Future research should assess the Association of prolonged daily use of new devices of media in the energy balance and the risk of chronic disease".

Central obesity, diet and metabolic syndrome

Although there were a few recent reports that fat distribution does not poses a health risk but total fat greater percentage, there were still many investigations on the impact of Central obesity on health, suggesting that visceral fat (internal) is a major health risk than subcutaneous fat (under the skin).

Metabolic syndrome is a condition that really describes the set of conditions that together much increases the risk of developing heart disease and type 2 diabetes. A recent book, published in February 2011, looked at central obesity and the metabolic syndrome and has determined that, after a Mediterranean diet it may help reduce the symptoms of the metabolic syndrome.

Conditions of the metabolic syndrome
"Disturbances" that lead to an increase in the risk of diseases of the heart and diabetes are:

CSC: excessive fat in the blood

Hypertension: hypertension blood pressure

Hyperglycemia - high sugar in the blood (glycemia) in obesity blood

Central - aka adiposity

Insulin of fat / Central resistance, also known as the visceral belly - fat when the body no longer meets the insulin and cannot reduce inflammation of the level of blood sugar levels

Low - when internal organs suffer inflammation in response to immunological problems.


It is estimated that the metabolic syndrome affects 34% of the population of the United States. OHS to increase the chances of developing diseases of the heart by 2 and the risk of developing type 2 by 5. Up to 34% of Americans now are 5 times more likely to develop type 2 are only those in good health.

Causes of metabolic syndrome

The main causes for the development of the metabolic syndrome are:

The socio-economic situation of the diet of habits

Low of exercise

Poor

Smoking

Lack

However, there is some evidence that a healthy diet can actually reverse the condition, or at least minimize the risk of development. And it is almost not lose weight, while central obesity is without doubt a problem yet. The answer seems to be the Mediterranean diet.

The Mediterranean diet and metabolic syndrome

Already, there was some research to suggest that obesity alone is not the cause of Metabolic syndrome. It seems that this happens that generally those who follow a diet that leads to insufficient Metabolic syndrome are also more likely to Central obesity.

The real issue is specifically the diet and not the level of deposits of fat in the body. The latest research examined the role of the Mediterranean diet and levels of metabolic syndrome and found;

"Accession to the Mediterranean diet (high consumption of whole grains, fruits and vegetables), olive oil, fish, dairy products that are low in fat and moderate wine consumption has been associated with low prevalence of food".

The study, 180 people suffering from metabolic syndrome at random, they were divided into two groups, a follow-up by the Mediterranean diet and the other continued prudent diet (generally low levels of fat and low in refined carbohydrate). 90 People in the Med diet, 78 people have been cured of all symptoms have metabolic syndrome.

Some parts of the Med diet that appears to reduce the metabolic syndrome are:

N-3 fatty acids and fish consumption

Olive dairy

Low oil

Low-fat

Glycemic Index and an increase of intake

Moderate wine consumption

Whole grains

Fruits and vegetables

Nuts

proteins


All these foods are for the most healthy and natural food.

What the research really shows is that, after that a healthy diet can quickly reduce the risk of developing type 2 diabetes. When diabetes is defined, it is very difficult to control. There are many serious problems to health associated with type 2 diabetes, amputations to increase the risk of diseases of the heart and the damage to the nerves, impotence and kidney damage and blindness.

Once more, the key is to eat a balanced, healthy diet and getting regular exercise.
