Nursing research critique and appraisal health and medicine homework help

Need help in completing this assignment (article summary of choice is below)

The purpose assignment is a critical appraisal of the strengths and limitations of the research process used to develop a systematic research review (SRR), meta-analysis or meta-synthesis. ***You are not critiquing the research process used in the individual studies contained in the research summary.

Outline of the Paper Tips:

Introduction for Paper: – introduce the topic/problem with supporting details from the literature. In other words, describe the relevance of the research problem, including the importance of the topic for nursing practice.  Describe the purpose of the paper. 

Body of Paper (using at least level one headings): 

  Critique of Research Rigor- rigor refers to the quality of following the research process.  Examples of questions that should be answered.  Was a research question presented in the SRR?  What is the importance in starting with a research question?  How was the literature search conducted and evaluated?  Who reviewed the literature?  What criteria was  used to select the studies for the SRR and how was the criteria applied?  Critique the level of evidence for the studies included in the SRR.  Was a specific level of evidence or research design an inclusion criteria? Why?   Did the SRR describe how validity of the individual studies was assessed?  Are the results in the SRR reliable and valid?  How do you know?   Provide an example to support your answer/s. 

  Critique of Level of Evidence – using the level of evidence pyramid determine the level of evidence for the studies included in the SRR.  For example, all 15 studies used a RCT design and represented Level II on the level of evidence pyramid. Also, explain how the level of evidence would influence future research and nursing practice decisions. 

  Critique of Clarity – How was the research information presented in the SRR–text? tables? charts?  Was the information readable? understandable?  presented in a way you, the reader, could analyze/evaluate the information? What recommendations could you offer? Provide an example to support your answer/s.

  Overall Findings – Synthesize the overall findings, then analyze the findings to answer the SRR research question.  What research limitations were addressed?  What was missing?  Why are research limitations important?  Provide an example to support your answer/s.

  Critique the Conclusions – Were the conclusions appropriate to the research question?  What were the implications for future research and current nursing practice.  Provide an example to support your answer/s.

Conclusion for Paper – restate the problem, summarize the main points, provide recommendations for future research and explain the importance for nursing. 

References: five minimal references r/t selected research summary topic and systematic research review process; The SRR reference will count as one of the five references.   

Estimated length: 5-7 pages (excluding title page and reference page/s)

Finally, a SRR is a research summary, not a research study.

ABSTRACT

Background

The prevalence of overweight and obesity in childhood and adolescence is high. Excessive body fat at a young age is likely to persist into adulthood and is associated with physical and psychosocial co-morbidities, as well as lower cognitive, school and later life achievement. Lifestyle changes, including reduced caloric intake, decreased sedentary behaviour and increased physical activity, are recommended for prevention and treatment of child and adolescent obesity. Evidence suggests that lifestyle interventions can benefit cognitive function and school achievement in children of normal weight. Similar beneficial effects may be seen in overweight or obese children and adolescents.

Objectives

To assess whether lifestyle interventions (in the areas of diet, physical activity, sedentary behaviour and behavioural therapy) improve school achievement, cognitive function and future success in overweight or obese children and adolescents compared with standard care, waiting list control, no treatment or attention control.

Search methods

We searched the following databases in May 2013: CENTRAL, MEDLINE, EMBASE, CINAHL Plus, PsycINFO, ERIC, IBSS, Cochrane Database of Systematic Reviews, DARE, ISI Conference Proceedings Citation Index, SPORTDiscus, Database on Obesity and Sedentary Behaviour Studies, Database of Promoting Health Effectiveness Reviews (DoPHER) and Database of Health Promotion Research. In addition, we searched the Network Digital Library of Theses and Dissertations (NDLTD), three trials registries and reference lists. We also contacted researchers in the field.

Selection criteria

We included (cluster) randomised and controlled clinical trials of lifestyle interventions for weight management in overweight or obese children three to 18 years of age. Studies in children with medical conditions known to affect weight status, school achievement and cognitive function were excluded.

Data collection and analysis

Two review authors independently selected studies, extracted data, assessed quality and risk of bias and cross-checked extracts to resolve discrepancies when required. Authors were contacted to obtain further study details and were asked to provide data on the overweight and obese study population when they were not reported separately.

Main results

Of 529 screened full-text articles, we included in the review six studies (14 articles) of 674 overweight and obese children and adolescents, comprising four studies with multicomponent lifestyle interventions and two studies with physical activity only interventions. We conducted a meta-analysis when possible and a sensitivity analysis to consider the impact of cluster-randomised controlled trials and/ or studies at ’high risk’ of attrition bias on the intervention effect. We prioritised reporting of the sensitivity analysis when risk of bias and differences in intervention type and duration were suspected to have influenced the findings substantially. Analysis of a single study indicated that school-based healthy lifestyle education combined with nutrition interventions can produce small improvements in overall school achievement (mean difference (MD) 1.78 points on a scale of zero to 100, 95% confidence interval (CI) 0.8 to 2.76; P < 0.001; N = 321; moderate-quality evidence). Single component physical activity interventions produced small improvements in mathematics achievement (MD 3.00 points on a scale of zero to 200, 95% CI 0.78 to 5.22; P value = 0.008; one RCT; N = 96; high- quality evidence), executive function (MD 3.00, scale mean 100, standard deviation (SD) 15, 95% CI 0.09 to 5.91; P value = 0.04; one RCT; N = 116) and working memory (MD 3.00, scale mean 100, SD 15, 95% CI 0.51 to 5.49; P value = 0.02; one RCT; N = 116). No evidence suggested an effect of any lifestyle intervention on reading, vocabulary and language achievements, attention, inhibitory control and simultaneous processing. Pooling of data in meta-analyses was restricted by variations in study design. Heterogeneity was present within some meta-analyses and may have been explained by differences in types of interventions. Risk of bias was low for most assessed items; however in half of the studies, risk of bias was detected for attrition, participant selection and blinding. No study provided evidence of the effect of lifestyle interventions on future success. Whether changes in academic and cognitive abilities were connected to changes in body weight status was unclear because of conflicting findings and variations in study design.

Authors’ conclusions

Despite the large number of childhood obesity treatment trials, evidence regarding their impact on school achievement and cognitive abilities is lacking. Existing studies have a range of methodological issues affecting the quality of evidence. Multicomponent interventions targeting physical activity and healthy diet could benefit general school achievement, whereas a physical activity intervention delivered for childhood weight management could benefit mathematics achievement, executive function and working memory. Although the effects are small, a very large number of children and adolescents could benefit from these interventions. Therefore health policy makers may wish to consider these potential additional benefits when promoting physical activity and healthy eating in schools. Future obesity treatment trials are needed to examine overweight or obese children and adolescents and to report academic and cognitive as well as physical outcomes.

PLAIN LANGUAGE SUMMARY

Lifestyle interventions for improving school achievement in overweight or obese children and adolescents

Many children and adolescents worldwide are overweight or obese. Children and adolescents who are overweight or obese have increased physical disease and emotional distress. They also perform less well on tests of thinking (cognitive ability), and they do less well in school. To prevent and treat obesity, several lifestyle changes have been suggested, for example, being more physically active, eating fewer calories and sitting less. These interventions are known to improve thinking skills and school achievement in children of normal weight. It is unknown whether the effects are the same in overweight or obese children and adolescents.

The review authors searched for studies that evaluated school achievement, cognitive ability and later life achievement (e.g. income, employment) in overweight or obese children and adolescents randomly assigned to a lifestyle intervention (aiming to being more physically active and/or improving diet and/or sitting less) or a control condition (e.g. standard care, no treatment). We found six relevant studies with a total of 674 overweight and obese children.

We found that, compared with standard school routine, school-based interventions targeting healthy diet and lifestyle education led to small improvements in overall school achievement in overweight or obese children. We also found that increasing physical activity improved scores on tests of mathematics and memory, and improved ’problem-solving’ thinking skills. No clear evidence was found

of an effect on other thinking skills related to reading, language or vocabulary. We found no studies that looked at whether lifestyle interventions affected achievements after leaving school.

Overall, despite the large number of childhood obesity treatment studies, only a select few evaluated the effects of obesity treatment on school achievement and cognitive function. The existing studies are limited in quality but suggest that lifestyle interventions could benefit overweight and obese children specifically in overall school achievement, mathematics, memory and specific thinking skills. Health policy makers may wish to consider these potential additional benefits when promoting physical activity and healthy eating in schools. Future obesity treatment studies could consider academic and cognitive as well as physical outcomes.
