美国代写论文：改善儿童健康的证据支持

美国代写论文：改善儿童健康的证据支持。研究表明，儿童的健康得到了改善，特别是在肥胖控制方面。研究表明，在超重女童的情况下，增加体育教育可以产生健康效果。这种积极的影响在孩子一年级和五年级的成长过程中会一直存在。因此，在中学阶段也能观察到这些好处。虽然在体育教育对健康的贡献方面存在性别差异，但研究证实，改善体育教育机会确实有助于在儿童很小的时候就控制肥胖。这项研究对幼儿园和一年级的学生进行了评估，其益处可以追溯到中学。接下来美国代写论文专家将为同学们讲解下改善儿童健康的证据支持。

肥胖干预并不是唯一的好处。许多研究确实指出了肥胖和健康干预之间的联系;然而，像哈里斯这样的研究指出，即使采取干预措施，减少肥胖也不会是主要的好处。对141名小学生进行的研究表明，当学校基础体育活动得到改善时，BMI没有变化(Harris et al, 2009, 719)。还有其他的健康益处，但是BMI和肥胖相关的健康益处没有得到显著的注意。比德尔等研究人员支持这一观点(比德尔2011,887)。从许多干预研究中可以观察到，如果身体活动得到了良好的提高，那么认知能力就有可能得到发展。提高认知能力和学习成绩是可能的。

再一次，局限性存在。例如，像斯图尔特这样的研究人员认为，有证据表明，身体活动和心理健康是有联系的，但研究设计往往相当薄弱，因此，联系被认为是小到中度的。然而，尽管存在显著性水平，但在这种关联中呈现的一致性证明了这一点。

研究分析表明，提高中学体育质量对帮助学生控制肥胖和其他健康益处是有一定必要性的。教师可能是成功的代理人，当涉及到发起这样的体育行动，学校课程也需要改进。学校的专业人员必须跟上时代的步伐，成为倡导体育变革的专家。这将确保获得最大的利益。

单独上体育课并不能提高健康质量。研究人员称，由卫生保健专家领导的班级的学生似乎比对照组的学生收获了更多的健康结果。因此，据观察，由健康教育专家教授的与健康有关的体育课程获益最大。因此，在体育课中加入特定的健康主题和相关的活动，可以给学生带来更多的好处

Obesity intervention is not the only benefit. Many studies do point out the connection between obesity and health interventions; however, studies like Harris points out that even with intervention obesity reduction will not be the major benefit. Studies conducted on 141 elementary school children revealed that BMI did not change when school based physical activity was improved (Harris et al 2009, 719). There were other health benefits, but BMI and obesity related health benefits were not significantly noticed. Researchers like Biddle support this argument (Biddle 2011, 887). It was observed from many intervention studies that where physical activity is improved on a good level, then it would be possible for there to be cognitive development. Improved cognitive performance and academic achievement are possible.

Once again, limitations exist. Researchers like Stuart for instance argue that there is evidence to show that physical activity and mental health are connected, but research designs are often quite weak and hence the associations are presented as small to moderate. However, despite the levels of significance, the consistency presented in such associations argues the case.

The studies analysis shows that there is a definite need to improve the quality of PE in secondary schools in order to help assist students in controlling obesity and for other health benefits. Teachers could be successful agents of change when it comes to initiating such PE actions School curriculum will need to be improved as well. School professionals must be brought up to date as specialists advocating change in PE. This would ensure maximum benefits are reaped.

Having PE classes alone did not improve health quality. According to researchers like students who were in classes that were led by specialists in health care seemed to be reaping more health results than students in control classes. Health related physical educations taught by health education specialists, hence were observed to reap the most benefits. Therefore, physical education classes when augmented with specific health focus and related activities could lead to much more benefits for the students。
