儿童肥胖症是由遗传易感性和行为之间复杂的相互作用引起的，主要与饮食习惯和体育活动有关。与成人相比，促进或防止儿童体重过度增加的具体行为因素的证据更为有限，对生长和发育的影响也不清楚。已经提出了一些行为风险因素，包括高能量密度的饮食、高含糖饮料消费量、大份量、饮食模式、高水平的久坐行为和低水平的体育活动。然而，大多数证据来自横截面研究，经常产生相互矛盾的结果。需要进行更多的前瞻性研究，准确测量身体成分方面的暴露和结果，以提供更有力的证据，作为实现长期行为改变和防止儿童体重过度增加的干预措施的基础。
Obesity in children arises from a complex interplay between genetic susceptibility and behaviour, primarily relating to dietary habits and physical activity. Evidence for specific behavioural factors that promote or protect against excess weight gain in children is more limited than in adults, and the effects of growth and development are not clear. A number of behavioural risk factors has been postulated, including diets with a high energy density, high consumption of sugar-sweetened beverages, large portion sizes, eating patterns, high levels of sedentary behaviour and low levels of physical activity. However, most evidence is derived from cross-sectional studies which frequently yield conflicting results. More prospective studies with accurate measures of exposures and outcomes in terms of body composition are needed to provide more robust evidence on which to base interventions to achieve long-term behavioural change and prevent excess weight gains in children.
