人体摄入的食物提供的能量用来维持各种生理和体力活动的正常进行。在生理状态下,能量代谢保持动态平衡,即摄入能量=消耗能量+贮存能量。当由于某种原因打破这一平衡使能量的摄入大于消耗时,机体储能的主要器官--脂肪组织内脂肪(主要为甘油三酯)堆积,体重超过标准体重20%以上者,称为肥胖。随着社会经济的发展和人民生活水平的提高,全球范围内超重/肥胖率急剧增加。肥胖与高甘油三酯血症、高血压、糖尿病在发病机理上密切相关,这些慢性疾病相互影响并常在同一个体聚集存在,肥胖引起的这种交互紊乱更是诱发和加重心脑血管疾病的重要危险因素。因此,研究和分析与肥胖相关的因素及相互关系,有助于肥胖的预防和治疗。
The energy provided by food in the body is used to maintain normal physical and physical activity. Under physiological conditions, energy metabolism maintains a homeostasis, ie energy intake = energy consumption + energy storage. When, for some reason, breaking the balance causes more energy to be consumed than it consumes, fat (mainly triglycerides), the main body of energy stored in the body, accumulates over 20% of its standard body weight and is called obesity. With the development of society and economy and improvement of living standards of the people, the rate of overweight / obesity has sharply increased worldwide. Obesity and hypertriglyceridemia, hypertension, diabetes is closely related to the pathogenesis, these chronic diseases affect each other and often exist in the same individual aggregation, obesity caused by this interaction disorder is induced and aggravate cardiovascular and cerebrovascular diseases Important risk factors. Therefore, the research and analysis of the factors and their relationship with obesity contribute to the prevention and treatment of obesity.
