孩子被诊断为肥胖后,医生将开始调查原因,导致这个孩子成为超重。首先,有几个原因导致孩子变胖。首先,许多孩子因为遗传肥胖。由于一些基因遗传自父母,那些孩子超重的风险更高。例如,不是所有的孩子看电视一天或几个小时是不活跃或只是吃mal-nutritious食品开发肥胖。因此,遗传被发现对肥胖的影响,身体的脂肪分布,对喂食过多的反应。它也表明,遗传不仅关注的基因也导致饮食习惯、食物摄入量,和生活方式,包括体力活动水平和自发的兴趣锻炼(PaE‡rizkova &山,2004)。此外,母亲超重是谁发现新生儿出生不活跃和获得更多的重量与新生儿出生体重正常的母亲相比,建议保存能量天生的驱动器。信息来自基因可以表明遗传因素可以作用确定添加或减肥的易感性在体力活动和饮食。一些孩子的生活方式也在肥胖中发挥作用。一些行为,在某些儿童(尾盘还是晚上吃饭、吃零食等)减轻肥胖的进展或持久性。孩子们每天花几个小时看电视,吃很多高热量的零食。食物只不过是容易做能量。势能是由热量测量中包含特定的数量和类型的食物。身体需要一个最低数量的卡路里为了执行其基本功能,为此和推荐的卡路里摄入量根据不同年龄、身体架,活动水平(比彻,Tessmer &哈根,2006)。肥胖儿童没有显示过度偏好甜食。儿童和成人只是欣赏高脂肪的食物。冰淇淋、蛋糕和饼干都是高脂肪食物的例子在肥胖和非肥胖的人都很受欢迎。体育活动是非常重要的实现适当的能量平衡,这是需要防止或逆转肥胖(Flamenbaum,2006)。此外,体内脂肪分布是影响独立的体育活动会影响体重。最后但并非最不重要,社会和经济条件有显著的营养和膳食摄入量的关系。例如,随着收入的增加,饮食的类型是更持久的方式可能会改变。特别是,糖、蛋白质和动物脂肪摄入增加,而蔬菜的摄入脂肪,碳水化合物和蛋白质减少。同样,如果家庭收入更高,可能有增加带走现成的食物摄入高脂肪含量或增加肉类的摄入量。较低的社会支持在低社会阶层与高食物摄入量和体重的儿童高。另一项研究表明,来自低收入家庭的孩子暴露在更少的认知刺激和谁有一个肥胖的母亲显示肥胖的风险增加独立于其他人口因素(PaE‡rizkova &山,2004)。然而,这些变化的总体效应在消费行为与高总脂肪的摄入量的增加肥胖的发生。
After the child gets diagnosed as obese, the doctor will start investigating the causes that lead this child to become overweight. To begin with, there are several causes that lead children to become obese. First of all, many children get obese because of heredity. Because of some genes inherited from parents, those children have higher risk of becoming overweight. For example, not all children that watch television several hours a day or are inactive or just eat mal-nutritious foods develop obesity. Therefore, heredity has been found to have effect on fatness, distribution of fat on body, and response to overfeeding. It has also been suggested that heredity does not only concern the genes but also resulting dietary habits, food intake, and lifestyle, including physical activity level and spontaneous interest in exercise (PaË‡rízková & Hills, 2004). Moreover, mothers whom are overweight are found to born neonates that are less active and gain more weight compared to neonates born of normal weight mothers, which suggest a preserving energy inborn drive. The information taken from genes can suggest that genetic factors can take role to determine the susceptibility of adding or losing fat in response to physical activity and diet. The life style of some children also plays a role in being obese. Some behaviors, present in certain children (late-day or night eating, snacking, etc.) ease the progress or persistence of obesity. Children spend several hours each day watching television, and eating lot of snacks that is high in calorie. Food is nothing more than easy to cook energy. The potential energy is measured by the calories that are contained in specific amount and type of food. A body needs a minimum amount of calories in order to perform its basic functions, and the recommended caloric intake for this purpose varies according to age, body frame, and activity level (Tessmer, Beecher, & Hagen, 2006). Obese children do not show excessive appetite for sweet foods. Children and adults simply enjoy foods high in fat. Ice cream, cakes, and biscuits are all examples of high fat foods which are very popular among obese and non-obese people alike. Physical activity is important for achieving proper energy balance, which is needed to prevent or reverse obesity (Flamenbaum, 2006). Moreover, distribution of body fat is affected independently by physical activity which affects body weight. Last but not least, social and economic conditions have a significant relationship to nutrition and dietary intake. For example, as income increases, the type of the diet is going more likely to change in a persistent manner. In particular, the sugar, protein and animal fat intake increases, while the intake of vegetable fat, complex carbohydrates and protein decreases. Also, if the family has a higher income, there might be an increase in take away readymade foods intake which is high in fat content or an increase in intake of meat. The lower social support in low social class is associated with a high food intake and higher weight of children. Another study showed that children from low-income families who were exposed to less cognitive stimulation and who had an obese mother showed an increased risk of obesity independent of other demographic factors (PaË‡rízková & Hills, 2004). However, the general effect of these changes in consumption behavior with the high intake of total fat is the increase in the occurrence of obesity.
