Obesity and the brain tissue hypoxia against an impact of intellectual
According to experts, some obese children, has shown early symptoms of cardiovascular disease, such as the early atherosclerotic vascular pathological changes, hypertension, increased left ventricular cardiac dysfunction, greatly affected the children's health.
With the continuing state of obesity, children adults, cardiovascular disease morbidity and mortality would be increased significantly. In simple obesity among young people, cerebral artery peak systolic velocity, end-diastolic flow velocity and mean blood flow velocity, significantly lower than non-obese adolescents; and found that changes in cerebral blood flow velocity, and cerebral blood flow change is proportional to, indicating overweight and obesity, adolescents, cerebral blood flow velocity changes, arterial blood flow slowed down to reduce cerebral blood flow per unit time, which led to brain tissue hypoxia, and may have an impact on intelligence.
【Related Tips】 At present, obesity has become troubled by a number of countries, particularly developed countries, health problems. At least 300 million people worldwide obesity, Britain has a quarter of adults and one fifth of childhood obesity. The medical profession that cause human obesity is mainly due to their absorption of calories (energy) more than the consumption, while the improper diet and lack of exercise is a key factor in causing obesity. Of course, genetics also account for a certain proportion.
Obesity, high blood pressure against 2 to promote the formation of atherosclerosis
Compared with normal children, children with severe obesity and expansion of decreased vascular compliance, vascular endothelial function decline; the same time, lipid disorders were more common in obese children, too much can promote lipid peroxidation, lipid peroxides The increase in the blood vessel endothelial cells are damaged, weakened blood vessel wall elasticity, tension increased, will promote the formation of high blood pressure.
Obesity and hypertension in children found that children of platelet aggregation with an increase in body mass index was significantly positively related to obesity, hypertension children, whole blood and plasma viscosity increased significantly contributed to the formation of coronary heart disease. Children and adolescents, if there are a number of risk factors, adult occurred atherosclerosis increased risk. Therefore, atherosclerosis and its complications prevention, in children or adolescence are most effective.
【Related prompted a new U.S. study shows that restrictions on children's television viewing time and allow them to maintain a certain amount of exercise, can effectively reduce the risk of childhood obesity. American Academy of Pediatrics has recommendations on measures to control childhood obesity, said that children watch TV every day time should be limited to 2 hours. However, the U.S. media recently reported that the U.S. Iowa State University researchers found that the majority of American children not meet these requirements.
3 lead to cardiac function against obesity will compromise
The study also found that obese children, due to cardiac involvement, caused by slowing blood flow, combined with chest wall thickening in obese children, diaphragmatic elevation, pleural fat accumulation, caused by inadequate ventilation, lack of these factors can cause the organization oxygen. Serum lipids in obese children increased, caused by increased blood viscosity, as well as reduced cardiac function, may allow blood flow to slow down, caused by micro-thrombosis, microcirculation perfusion.
Simple obese children in sports, the need to use energy reserves in advance. Treadmill exercise test with an example, these children after exercise, heart rate recovery time was prolonged, nearly 1 / 4 of obese children movement, ECG abnormal, indicating increased stroke volume alone, can not meet the body's needs, the need to expedite heart rate, heart rate and prolong the recovery time in order to increase the body's oxygen supply, which is a compensatory cardiac reserve in advance to use way.
The burden of excessive fat in obese children, causing them to activities, palpitation, shortness of breath and even less active, so that fat accumulation of more long-term cardiac overload, is bound to fatigue, a long time of cardiac function must be compromised. Once the heart of compensatory over the limit, will result in reduced stroke volume, and more limited mobility, forming a vicious cycle.
