Not long ago, a senior university student suddenly asked me: now there are four big monsters in society, do you know? I asked: which four strange? He said: the poor just ate big fish and meat, but the rich people are eating nests of wild vegetables; the poor just put on suits and shoes, but the rich people are going to wear casual casual; the poor just drove on the car, but the rich people are going to walk on foot; the poor just live in skyscrapers, but the rich people are going to the countryside to live in thatched huts. I said: looks strange, in fact, is not strange, which precisely reflects the change of health concepts. Rich people take the lead to return to nature, health as fashion, the scientific lifestyle as a new pursuit. Having said that, I would also like to tell a true story. A small island storm in the South Pacific Islands, there is a beautiful island called “Nauru”, the island is inhabited by more than 10,000 people, they are always fishing and hunting for a living, and generations have lived in poverty and hunger, a hard life. But who would never have dreamed that this small island has become the richest people in the world overnight, what is going on? In the early 1980s, some people unintentionally found the original island covered with a thick layer of bird droppings, the thickness of how much thirteen or fourteen meters, its bird droppings are rich in phosphorus resources, is an excellent phosphorus fertilizer. Once the news spread, developers from all over the world flocked to the island, a large amount of gold and silver rolled to the island flow, where people no longer need to fish, imported delicacies piled up on the table, high-fat, high-sugar, high-protein, high-calorie diet to enjoy every day, coupled with a long period of time not to participate in the work of a disaster has also descended. Small island in less than two decades, fat men and women fat children abound, during the Shanghai World Expo, Nauru opening day show is fat fat show, however, behind him, it is the rich and wealthy disease flooded, high blood pressure, coronary heart disease, diabetes, strokes, fatty liver, hyperlipidemia, gout disease, metabolic syndrome. Rampant rampant, to diabetes, for example, in the 1950s, here almost no use of diabetes, but the incidence of diabetes is as high as 40% or more, 55-65 years of age of middle-aged and elderly people even more than 60%. Young women suffering from diabetes, the rate of live births of their babies is no longer 50%, half of the small life miscarriage, premature birth, stillbirth, early death, here has become the world’s shortest average life expectancy in the country, many people in their fifties and sixties on the disability and death, the heavens, the earth, this is what happened?! According to the World Health Organization in 2010, Nauru has become the fattest country in the world, with 97% of adult males and 93% of adult females in the country being overweight and obese, and nearly half of Nauruans suffering from diabetes. Nauru is just a microcosm of the rapid changes in modern society, which covers an area of only 21 square kilometers, the population of less than 10,000 people, but if the geographical area is enlarged to 9.6 million square kilometers, expanding the population to 1.3 billion people, we have not felt a hint of shudder? In fact, China’s diabetes epidemic is very similar to that of Nauru, only not as severe. As a classic case in the history of medicine, Nauru people with their own bodies and health to verify the fact that: high-calorie diet + lack of exercise lifestyle significantly induced obesity and diabetes, high blood cholesterol, high blood pressure occurs, this situation would have become a metabolic syndrome, due to its great harm, known as the “death quartet”. Second, the death quartet – metabolic syndrome obesity, diabetes, hypertension, hypertriglyceridemia and other clinical diseases gathered not by chance. 1988, the famous American endocrinologist Reaven found insulin resistance, and insulin resistance, hyperinsulinemia, glucose tolerance, hypertriglyceridemia and hypertension collectively referred to as “syndrome X “. The metabolic syndrome that is now commonly referred to in the medical community as Reaven’s syndrome is the metabolic syndrome. Because each component of the metabolic syndrome is a risk factor for cardiovascular disease, their combined effect is stronger, so some people will metabolic syndrome called “death quartet” (central obesity, high blood sugar, hypertriglyceridemia and hypertension). With the improvement of people’s living standards and lifestyle changes, the body overweight, high blood pressure, high blood sugar, high blood fat and other chronic diseases more and more, and many people take it for granted and do not take it seriously. But careful observation will find that these symptoms often occur in a person at the same time, it is not a coincidence, if the above indicators at the same time, it can be diagnosed with a serious threat to health, known as the “death quartet” of metabolic syndrome. As early as in the 60s, medical experts found the phenomenon and harm of abnormal blood sugar and cardiovascular disease aggregation, and carried out continuous research, and finally put forward the concept of “metabolic syndrome”, and issued a “metabolic syndrome” of the global unified definition: 1. The center of obesity (China’s male waist circumference > 90cm, women > 85cm waist circumference of different races have their own reference value); 2, the combination of the following four indicators of any two: (1) triglyceride levels increased, greater than 1.7mmol / l, or have received the appropriate treatment; (2) high-density lipoprotein – cholesterol levels decreased: male less than 1.03mmol / l, female less than 1.29mmol / l, or has received appropriate treatment; (3) increased blood pressure: systolic blood pressure ≥ 130 or diastolic blood pressure ≥ 85 mm Hg, or has received appropriate treatment or previously diagnosed hypertension; (4) increased fasting blood glucose, greater than or equal to 5.6 mmol / l, or previously diagnosed with type 2 diabetes mellitus or has received appropriate treatment. China’s diagnosis of this syndrome accounted for about 20%-40% of the middle-aged and elderly population. The prevalence of the syndrome is higher in the north than in the south, and higher in urban than in rural areas; the prevalence of metabolic syndrome gradually increases with age. As each component of the metabolic syndrome is a risk factor for cardiovascular disease, the risk of multiple risk factor aggregation is greater than only one risk factor, and its effect is not simply additive, but synergistic exacerbation, so that the occurrence of diabetes mellitus and coronary heart disease and the risk of other cardiovascular diseases increased significantly. The name “death quartet” (central obesity, hyperglycemia, hypertriglyceridemia, and hypertension) is derived from this. Obesity and low physical activity are the main factors influencing the current rapid increase in the incidence of metabolic syndrome. Third, what should be done? It is more important to prevent metabolic syndrome, especially for the urban white-collar workers who often socialize, sit still for a long time, and have a lot of psychological pressure, it is more important to strengthen physical exercise from now on, and to change the bad lifestyle such as smoking, drinking, overeating, lack of sleep, and seldom exercise. For some high-risk individuals, such as those who are already overweight or have a family history of hypertension or diabetes, they should regulate their diets, control their weight and insist on exercising from childhood or young adulthood. Early diagnosis of metabolic syndrome is still difficult, and unless the individual is already experiencing significant symptoms, the disease has often progressed to an irreversible stage by the time it is diagnosed. With Nauru’s phosphate mines nearly depleted and the country’s economy on the brink of collapse, no one knows what the fate and health of Nauruans will be tomorrow. But as us, it is possible to take control of our own health by controlling our diet, increasing physical activity and mental coordination – it’s all about perseverance!
