This paper seeks to evaluate an article that under the title: “Hormonal responses and test meal intake among obese teenagers before and after laparoscopic adjustable gastric banding.” The article was written by ten authors and was registered with the government under clinical trials as CT00764127. The article appeared. The article appeared in the American Journal of clinical Nutrition in the year 2013 issue 98 pages 1151 to 1161.

The article displays a scientific type of paper as it starts with a heading that carries the main aim if the article. The article has an abstract with five components of background, objective of the paper, design of the experiment, results and conclusion. The paper’s objective goes hand in hand with the title as is stated as: “to compare eating and hormones among adolescents with a bariatric surgery program with non-overweight controls and evaluate changes before and after laparoscopic surgery.”

In the introduction, the authors clearly portray the need that prompted them to do this study. They argue that the previous studies on eating behavior and hormone were not very objective in the assessment of eating behavior with hormonal analyses in adolescents or adults undergoing bariatric surgery. They authors have used the need identified to state their study purpose as; to measure and relate eating behavior in very obese adolescents undergoing bariatric surgery, and compare with non-overweight. The article draws and hypothesis from the view of the authors, and it also hypothesizes from researches previously done. The introductory part also introduces the reader to the area of study and orients them to the setting of the experiments. The subjects-adolescents are introduced and what the reader will find in the other sections.

The article has by now passed the scientific test of having been read by two categories of audiences. Having appeared in the American Journal of Nutrition, the article must have passed through referees who recommended it to the editor of this journal.

The materials and methods are well laid out for the reader. The setting of the experiment is specific: Morgan Stanley Children Hospital of the New York Presbyterian/Columbia University Medical Centre. The eligibility criterion that was used is evident, for example, in terms of age, weight, and serious comorbid conditions. The criterion for the control experiment is well spelt out by the article.

The systematic process for procedures employed in the article shows agreement with the scientific process. Consent was obtained from the participants and even from the parents. The in person screening, clinical interviews with a psychologist and clinical physical assessments show the scientific viability of the study. The explanation brought out for materials and methods shows originality and authenticity of the article. The involvement of previous researches and comparing them in the article is a further emphasis that the article is first-hand. The article displays the average of calories for each food consumed across the groups in table form. Use of table forms is recommended for scientific papers.

Measurements and analyses of foods were done scientifically by nutritionists at the Irving Institute for Clinical and Translational Research of the Columbia University Medical Center. The researchers ensured that food analysis was made using Nutrition Data System for Research Software version 2009. Again, using specialized personnel for a specific task and the right equipment for a procedure shows the commitment of the authors to a scientific research process. Testing of the participants before and after the experiment show the author’s’ commitment to ensuring the credibility of their findings. The authors present their results in a systematic consolidated standard of reporting trials.

Scientific methods were used to present the data. The authors used the Statistical Package for Social Sciences version 18 to analyze their data. This and the accompanying fact that the authors used independent t test samples to analyze data shows adherence to the scientific process. In their discussion, the authors have followed their objective well. They have compared data with their control participants as well as with the other researches done in this field. In the conclusion section, the researchers have identified areas of further research and made the necessary recommendation meeting the requirements for a systematic research process.it is a science paper because it has followed the scientific process.

The American Journal of Clinical Nutrition publishes some of the latest world-over clinical, basic studies on human nutrition. It is the highest rated peer reviewed journal in the world. Having appeared in this journal, this article is highly rated in the field of nutrition. The principal investigator in the article and co-authors are high ranking personalities in the field of science. Robyn Sysko, for example, is an assistant professor of clinical psychology at the New York Institute of psychiatry. Tanofsky Krapf is a psychologist with the Catholic University of America.

To conclude, this article meets the criterion of classifying it as a scientific paper. It is organized into sections and each section adheres to the demand of the scientific process.
