3, simple obesity epidemiological etiology study 3.1 abnormal body fat distribution and changes in body mass With the deepening of industrialization, mental work gradually replaces physical work, and with the reduction of outdoor activities, abdominal obesity gradually becomes independent of genetic factors, the main manifestation of acquired obesity, accounting for the majority of simple obesity, and has the tendency to develop to a variety of serious diseases. Pietilainen [5] et al. found that, independently of genetic factors, acquired obesity was positively associated with abdominal visceral fat content, liver fat content and insulin resistance (IR) by observing 19 monozygotic twins aged 24-27 years with body mass index (BMI) ranging from 20.0 to 33.9 kg/m2. Riserus [6] et al. studied 59 moderately obese patients to measure sagittal abdominal diameter (SAD), body mass index (BMI), waist circumference, waist-to-hip ratio (WHR), insulin sensitivity, and plasma insulinogen levels in the prone position. The results showed that SAD better reflected insulin sensitivity than other measures and was the only predictor independently associated with IR and hyperinsulinogenemia. A study by Kun-San Xiang et al [7] further confirmed the presence of hyperinsulinemia and decreased insulin sensitivity in obese patients, and concluded that increased intra-abdominal fat is the main cause of IR. The above clinical findings show that the abnormal distribution of abdominal fat not only causes changes in the morphological structure but also in turn affects the functional metabolism in the body. 3.2 Changes in the structure of daily diet Modern people have a one-sided understanding of nutrition and prefer to eat fatty, sweet, thick and greasy, Western-style fast food, which is difficult to digest, has a long metabolic cycle, can increase serum low-density lipoprotein (LDL-C), and often strong food and drink, which can easily cause stagnation in the spleen and stomach, which hinders transport and transformation, thus becoming damp-heat. Li Changyou [8] showed that the results of a dietary survey of a kindergarten in Jilin showed that: carbohydrate: fat: protein = 57: 26.1: 16.9, total caloric energy was 10% higher compared with RDA, and total calories were high; the proportion of high quality protein to total protein was higher. Analysis of this kindergarten recipe reveals that the high animal food has a tendency to form obesity. Also this shows that there are misconceptions about dietary nutrition. Another example is the “100 Questions of Ryukyu? Ryukyu original question” said: “the earth eats people with five flavors, taste has thick and thin, the original can not be partial, partial to the thick, more depression for heat, heat is better than the stomach, moisture of water and grain Mo is not subject to its fumigation, moisture and heat are knotted, clear and turbid dry, gas is difficult to pass Thai.” The introduction to medicine? Phlegm”: “hot phlegm because of thick taste accumulation of heat, …… food phlegm because the diet does not transform.” And the modern refrigerator popular, drinking cold day as a rule, the Yang is damaged, water and dampness can not be transported plus fat, sweet and thick taste is difficult to digest, resulting in damp heat accumulation in the spleen and stomach, etc.. It can be seen that dietary factors are the main cause of damp-heat. For a long time people have always thought that fat cells in the development process of obesity only as a storage site of lipid, does not play a regulatory role. But in recent years research found that adipocytes also have important secretory role, it can control food intake and regulate energy metabolism by secreting certain hormones, cytokines, etc., such as tumor necrosis factor (TNF-α) is a multipotential cytokines, it can directly or indirectly affect the body lipid metabolism [9, 10]. 3.3 Environmental pollution and artificial hypothermic environment invasion In modern industrialized society, environmental pollution is an important factor that endangers the human living environment, and the physical state of humans is decreasing. The widespread use of air conditioners and refrigerators has caused artificial low temperature climate, which greatly increases the chance of the body being exposed to “cold evil”. Suwen? The six micro-intentional great treatise: “up and down the position, the gas intersection in the middle, the human residence also.” Su Wen? Jin Kui Yao Yin”: “The five Tibetan elements respond to the four seasons, and each has its own reception”, which all indicate that climate changes are closely related to the physiology and pathology of the human body. Su Wen? The Eight Divine Minds: “When the day is warm and bright, the blood of the human body is fluid and the body gas is floating, so the blood is easy to diarrhea and the gas is easy to move; when the day is cold and cloudy, the blood of the human body is condensed and the body gas is sinking”. This explains the effect of climate changes in temperature and cold on the operation of human qi and blood. Ling Shu? The five addictions and fluids are different, and the four climatic changes and the adjustment of the body’s water metabolism made a detailed observation: “the day of the summer clothes thick knees open, so sweat. …… day cold is the knee reason closed, gas astringent does not work, underwater flow in the bladder, it is drowning and gas.” The above arguments are enough to prove that artificial low temperature climate is a huge impact on human physiology and pathology. Yuan Yang Qi is the driving force of various vital activities, cold is the gas collection, Qi is not smooth, so a variety of metabolites accumulate in the body, affecting the normal metabolism of water and fluids, and finally the formation of wet phlegm food and blood depression. 3.4 Emotional and mental factors influence the “acupuncture and moxibustion A B Jing? Spiritual five organs first: “…… sad is the heart system is urgent, the lung cloth leaf lift, the two jiao is not accessible, the camp guard is not dispersed, heat in the middle, so the gas is eliminated. The cold is the coup closed, the camp guard does not work, so the gas collection. …… thinking then the heart has hurt, God has stopped, the gas stays and does not work, so the gas is knotted.” It indicates that excessive emotions can lead to impaired qi flow. Japanese scholar Katsutaro Nagata [11] believes that chronic stress is one of the main causes of blood stasis, and the stasis state is the low serum coenzyme Q state, which is a chronic stress response, that is, although the sympathetic nerve releases catecholamines while its target organ, the myocardium, is in a state of strain, causing constriction of the smallest arteries throughout the body and impaired peripheral blood circulation, resulting in stasis of blood in the capillary system and venous system. Some scholars have investigated and analyzed the relationship between coronary heart disease bruising evidence and type A personality, psychological stress, and found that emotional and mental factors are closely related to bruising. All of the above indicate that adverse emotional factors can affect the operation of qi, producing qi stagnation qi depression qi chaos, etc. Dai Yuanli explained: “The depressed, the gathering can not be sent over. When the line is not allowed to line, when the drop is less than the drop, when the change is not allowed to change, this is the transmission and transformation is not normal, the six depression of the disease is seen.” It can be seen that the emotional factor is also an important cause of disease related to the rise and fall of the clear, the transformation of the transmission of change. 3.5 wrong cognitive guidance advertising media often have a specific commercial purpose, the modern aesthetic tendency of depressed, sickly bony beauty, so that people have the wrong aesthetic cognition, the blind pursuit of “weak” beauty. Or take extreme means of weight loss, such as vicious dieting or blindly taking laxatives, diet pills or addiction to cold products causing artificial diarrhea and dehydration to lose weight, etc. The result is counterproductive, often causing abnormal distribution of abdominal fat due to Qi deficiency, Yang deficiency, cold condensation and blood stasis. Also in the era of medical examination, most people look at the “normal value” obtained from the physical examination at the time absolutely, and consider the problem or make a judgment based on the numbers. When there is a “form-qi mismatch”, although the objective examination values are within the normal range, they are often already in a “sub-healthy” state. People often do not recognize this, resulting in the progressive development of biased physique. With the improvement of social productivity, the material products of people’s lives are becoming more and more abundant, but at the same time the lack of knowledge of health care makes people think that satisfying all their desires is a reflection of the progress of civilization. Therefore, “wine as a pulp, delusion as a regular, drunk to enter the room, want to exhaust its essence, in order to dissipate its true, do not know to hold full, from time to time, the gods, and the heart of the matter fast”. Therefore, over time to form damp heat, phlegm damp, blood stasis physique, and then on this basis to produce obesity, and then all kinds of pathogenic factors into the body easy to quality into phlegm stasis, resulting in qi and blood stagnation, the formation of various complications of obesity.
