儿童单纯性肥胖的形成机制目前尚不清楚。环境因素,如生活方式的改变、饮食结构不合理、坐着看电视的时间延长以及便利的交通条件带来的体力活动水平的下降,在肥胖的发生中可能起着重要作用,加之遗传因素的作用使其易感性增高,导致能量代谢失衡而发生肥胖。儿童肥胖状态下是否存在能量代谢方面的变化,能量代谢在儿童肥胖形成及维持中的作用如何,国内尚未见有报道。国外学者对单纯性肥胖儿童的能量代谢进行了研究,但得出的结论却不一致。 The mechanism of simple obesity in children is not yet clear. Environmental factors, such as lifestyle changes, unreasonable dietary patterns, prolonged sit-in on television and decreased levels of physical activity due to convenient traffic conditions may play an important role in the development of obesity, in addition to genetic factors Its role to make it more susceptible, leading to imbalance of energy metabolism and obesity. There is no change in energy metabolism in childhood obesity, and the role of energy metabolism in the formation and maintenance of childhood obesity has not yet been reported in China. Foreign scholars have studied the energy metabolism of simple obese children, but the conclusions drawn are not consistent.
