Evidence-Based Practice




Beingan interdisciplinary approach, evidence based practice (EBP) providesa dynamic and broad perspective to nursing and the entire clinicalpractice. The EBP has spread over several health fields, includinghealth education, dentistry, psychology, information science and inthis case nursing. In nursing, evidence-based practice is applied inthe provision of basic health are and making decisions by consideringrelevant research and most recent information. To explore theimportance of evidence-based practice in nursing, this paper willanalyze “Effective Dietary Interventions for Overweight and ObeseChildren” that provides a research on child obesity. With referenceto the research, this paper will discuss why evidence-based practiceis important to nurses in addition to the importance of research.Moreover, this paper will utilize a checking order to rank andappraise the selected piece of research on child obesity andoverweight.

Importanceof Research to Nursing

Researchis important to nursing in three main perspectives that form thebasis of learning and nursing practice. First, the research providesa learning opportunity for nurses to gather, acquire and internalizenew knowledge and information. This is because research helps nursesto acquire information about their areas of practice and generalhealth care knowledge (Tingen, et al, 2009). Through research, newinformation and knowledge of nursing and health care processes isacquired by nurses who use it to improve their skills. Onceinformation and knowledge is internalized, nurses gain expertise thatis evidently portrayed in their practice. Consequently, researchcontributes to the discovery and learning of new skills that makenurses effective and efficient in their practice.

Secondly,the research provides a tool or an approach that gives answers tohealth care questions and issues that need clarification for betterunderstanding. Research is used to find solutions to the issues thatrelate to certain disciplines of nursing and health care. Tounderstand factors that affect and influence childhood obesity,research give a nurse a perspective of questioning every fact orstatistic with a view to understanding the phenomenon. In the case ofunderstanding childhood obesity, research provides a basis ofexploring the causes of obesity in children, the extent of theconsequences of obesity to children and their perception of thecondition.

Finally,the research provides the nursing practice with a basis of developingthe practice by introducing new fields and skills. The researchprovides new information that develops into specialties in terms ofpractice in health care and nursing. For instance, in the researchabout childhood obesity and overweight problem, new information onthe causes of children`s preference of high density and high energyfoods can help discover ways of training and teaching them to avoidthese foods. As a result, such a perspective of reducing childhoodobesity develops into a community health nursing specialty oftraining on proper diet. Through the use of the statistics from theresearch, the nursing personnel are able to learn these new areas andutilize them into new fields of specialization.

Importanceof to nursing

Evidence-BasedPractice helps in making decisions that are informed of the mostrecent findings and relevant research in the nursing practice.According to Houser and Oman (2010), the decision making is based onclinical expertise that is proven to be effective and efficient byresearch. The research about child obesity and the dietaryinterventions for obesity and overweight problems in children isimportant for gathering information about the problem. Taking theresearch on childhood obesity, the main aspect of concern is thestatistics of obese children and the interventions that can beapplied to the issue. Therefore, this research is important fornursing because it provides the information that a nurse should beequipped with to handle cases of overweight children.

Evidence-BasedPractice is important to nursing since it cultivates a sense ofinquiry in every step or process of the practice. The sense ofinquiry takes the form of an attitude or perspective of a nurse,which prevents him or her to make decisions or implement procedureswithout inquiring the progress or expected outcomes. Throughresearch, the inquiry points are answered and pave way for informeddecisions, procedures and outcomes (Houser &amp Oman, 2010). Thisattitude and inquiry spirit allows nurses and health workers toquestion the present methodologies in nursing and the challenges thatface the practice. As a result, such research helps to introduce newdevelopments or changes that make the practice better.

Evidence-BasedPractice provides the basis of collecting the most relevant evidencethrough the use of keywords. After carrying out a research on anissue, the results found help in the creation of possibleinterventions for the health situation, or the treatment of thecondition. From the results, the research can be rated so as toindicate the outcomes that indicate the strongest evidence (Houser &ampOman, 2010). From these ratings, the interventions or options withthe greatest levels of evidence is applied to the health field thatrelates to the question of the study. In the case of childhoodobesity, the data on the type of foods taken and the outcomes interms of weight gains in children can be used to determine theevidence of relationship between each food and obesity.

Moreover, is important to nursing by providing a basisthrough which health, safety and welfare of patients is improvedthrough continuance developments. Through proper Evidence-BasedPractices, the nurses are able to adopt proven methodologies in theirclinical practice. This is because there is proven evidence of eachmethodology or approach that is applied in nursing or any relatedhealth care practice (Houser &amp Oman, 2010). Evidence-BasedPractice in nursing is based on the gathering of relevantinformation, interpreting it, appraising the findings and integrationof the ranked research. Therefore, helps thenursing community to develop their skills to match the currentexpectations. These expectations include acquisition of appropriateknowledge as a nurse, studying of evidence and patient preference.

Rankingof the article

Theauthors of the article researching on childhood obesity have theappropriate educational credentials as well as the clinicalqualification. This gives authority to the research and validates thegap that the research article tries to solve. Due to the expertise,there is no conflict of interest for the writers of the articles.This avoids the risk of bias of the research outcomes and subsequentpoor intervention measures. From the set up of the article, there isevidence of a peer reviewed journal. This is because, the pages aresequentially numbered for the whole year, and the issues areidentified by the number and the volume.

Thearticle has no financial relationship or a connection to financingelement in terms of the positive and negative results. In addition,the study about childhood obesity has a reasonable time frame. Thearticle shows that the research was done in a reasonable timeinterval, especially in the intervention stage of the research. Forinstance, for one case of adolescent children studied for overweigh,the study took 8 weeks and a similar intervention took 8 weeks (JBI,2007). Each of the interventions is based on the level of the trialof the Randomized Trials and the Non-Randomized Controlled trials.

Appraisingthe level of evidence the recommendation Strength

Thearticle rates highly as per level 1 rank since it describes aresearch that used multiple randomized trials (RTCs). The RTCsprovide the research results at the times needed such as at theintervention, post-intervention or during follow up procedures. Inaddition, the research reports its multiple RTCs as meta-analysisreview. According to the JBI (2007), the results were studied using ameta-analysis of a subset of the RTCs used. The research uses 8 RTCsin total that had the control group as well as the dietary component.This makes the research relevant for the nursing practice. Forinstance, the meta-analysis of the research demonstrates that dietaryinterventions are more effective in controlling weight gain andpromoting weight loss to handle obesity (JBI, 2007).

Interms of level 2, the research ranks highly since it uses both theRTCs and Non-Randomized Trials. For instance, the research onchildhood obesity had a hypo-caloric strategy called the trafficlight diet used as a common element to many of its RCTs. According tothe JBI (2007), this diet used as RCT is a calorie controlled dietthat ranges from 1200 to 1500 Kca/Day. The researchers used thetraffic light imagery of green color as low calorie healthy food,yellow as medium calorie food and red as high calorie junk food.Therefore, children are advised to take the food with greenindication, as a way of promoting the nursing job of intervening inthe overweight problem.

Theresearch does not rank well in terms of level 3 and level 4 since itdoes not adopt the use intact groups or ex-post-facto. In addition,the research does not adopt casual comparative studies, case studycontrols, integrative reviews or theory-based opinion. The evidenceof the research is not obtained from a time series of experiments orquasi experiments.

Evidenceof Peer-Reviewed Article

Theevidence that this article is a peer-review article is present in theway the pages are sequentially numbered for the whole year asindicated on all the pages. The issue is identified by volume and thenumber. In addition, has an external editorial board with expertisein the field. Being a peer-reviewed article is important because itproves the validity of the article and the reliability of theresults. The results are reliable to the nursing practice if they arewell reviewed by experts. Consequently, the interventions adoptedwill be effective in promoting weight loss and controlled weightgain.


Thearticle under review is a peer-reviewed research that focuses on thedetermination of effective dietary interventions that can handle theobesity problem in children. While research is important to nurses,evidence-based practice provides greater importance to nursing bypromoting the adoption the best interventions. In the case of thepeer-reviewed article, the research provides interventions that showthe importance of appropriate level of evidence in giving strongrecommendations for the practice.
