The United States leads the world with obesity. According to a survey conducted by the Centers for Disease Control in 2010, China's 35.7% Body Mass Index (BMI) has exceeded 30. This is a slow but steadily rising figure. In the same study, it has also been reported that approximately 12.5 million American young people are obese. In June 2013, the American Medical Association officially listed obesity as a chronic disease. Obesity is associated with many preventable diseases and is one of six of the top 10 deaths in the United States.
The long-term concern of obesity of greatest concern is the increase in atherosclerotic cardiovascular disease (ASCVD) and the associated physical influence. As the number of overweight and obese people continues to increase, it is important to understand the effects of these cardiovascular systems, to prevent obesity-related heart diseases and to implement evidence-based strategies to extend life expectancy is. Visceral obesity in the omentum region and intestinal region (so-called "apple constitution") is a powerful risk factor for the development of hypertension, dyslipidemia, coronary artery disease and type 2 diabetes (DM) insulin resistance. Unlike peripheral adipocytes, visceral adipocytes are more tolerant to insulin and are more sensitive to lipolytic hormones, thereby increasing the release of free fatty acids, and for the synthesis of liver triglycerides Providing a larger substrate.
Insulin resistance is essentially inevitably associated with obesity and usually precedes the onset of type 2 diabetes. 8 Abdominal obesity, especially visceral fat, has been thought to be responsible for insulin resistance. In a study of 32 overweight or obese Hispanic children, it was shown that the increase in visceral fat is not associated with increased insulin resistance and decreased insulin secretion. Characteristics, but even those who are not normally obese are also significantly increased during normal adolescence, even between 10 and 12 years of age
Obesity is becoming more common in society after industrialization, the burden of childhood obesity is increasing. The main effects of obesity on cardiovascular (CV) health are mediated by the risk of metabolic syndrome (insulin resistance, dyslipidemia, hypertension). Individuals who have been diagnosed with chronic CV disease (CVD) have a significant correlation between overweight and grade I obesity and improved survival. However, this effect is attenuated by the increase in cardio and pulmonary health. Adverse effects of obesity on cardiovascular health are the promotion of atherosclerosis, increased ventricular remodeling, and increased risk of related diseases including stroke, myocardial infarction, heart failure.
