Assessment 1: Critical Literature Review
Assessment: 1 – Critical literature review
Learning objectives assessed: 1, 2
Submission: Blackboard via Turnitin submission link
The purpose of this course is to develop research skills from the early stages of identifying a
research gap and research question to developing a research proposal and completing an ethics
application, using a hypothetical example. Each assessment within this course will build on the
previous assessment, so the topic you choose for Assessment 1 and the research question you
identify will be the basis for your research proposal (Assessment 2) and ethics application
(Assessment 3) that you will develop over this semester. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Complete a critical review of the literature on your topic to identify a research gap and conclude
with a clear and succinct research question. Due to the scope of this assessment, it is NOT expected
that this will be a systematic review, however a systematic approach to searching a database is
expected. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Step 1 – Choose a topic
Choose an area of interest from one of the following broad topic areas:
• Maternal and child health
• Communicable diseases including sexually transmitted infections
• Major non-communicable diseases (cardiovascular disease, diabetes, cancer or kidney
• Environmental health
You might have a specific area of interest already within one of these broad topic areas, otherwise
you will need to do some brainstorming or use a mind map to help you narrow the focus for your
literature review. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Step 2 – Conduct a literature search to identify relevant articles
You will need to conduct a search of one database (available through UQ Library) such as PubMed,
Web of Science or Embase to find articles on your chosen topic. You will need to include the
search strategy in your report so make sure you keep a copy of the search terms you use. In
developing your search strategy, think through what are the key terms or concepts that make up
your specific topic/question. Refer to week 1 lecture for developing your search strategy. Once you
have completed your search, read the abstracts of the articles to identify at least 10 peer-reviewed
journal articles to critically appraise and include in your review.
Where available/appropriate you might choose to use a systematic review or meta-analysis that you
identify in your search as one of the articles you use in your literature review. Consider including
both quantitative and qualitative articles. For example, if your topic/question is more quantitatively
focused, consider including a qualitative article in your literature review and vice versa.
Step 3 – Read, extract and assess included articles
Once you have selected the articles to include in your literature review, you will need to read the
full-text of these articles in detail so that you can critically appraise the literature. Select 5 articles
from your review and extract the relevant data from these articles to tabulate in a Summary
Table. Refer to Week 2 and 3 lecture notes for examples of Summary Tables. If the 5 articles you
choose to include in the summary table are different study designs, you may choose to use different
tables/formats for presenting the summary from these studies. For these same 5 articles, choose the
appropriate critical appraisal (risk of bias assessment/methodological quality) tool, and present
your quality assessment of these articles in a table. Refer to Week 2 and 3 lecture notes (and
PUBH7600 lecture notes) for critical appraisal tools. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Step 4 – Literature review write-up
Write up your assignment as follows, including a title for your literature review:
Introduction: (approx. 300 words)
Briefly describe the public health problem (e.g. define the topic, incidence/prevalence/mortality
rates, trends etc) including the rationale for why it is important and significant to focus on.
Literature search strategy and quality assessment: (approx. 100-200 words)
State your search strategy – the database searched and search terms. Indicate the critical
appraisal/quality assessment tool(s) used to assess the studies and any modifications/interpretations
of criteria specific to your topic. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Critical review of literature: (approx. 1200 words)
Critically review and summarise at least 10 academic papers identified from your database search
(these should be different articles to what you have included in your Introduction section to define
the topic and the importance). Summarise the key aspects of the studies (referring to your Summary
Table as appropriate) and compare and contrast the findings from the articles. Summarise the
methodological quality of the studies you have reviewed. What are the strengths and limitations of
the evidence that you have reviewed? You may choose to use subheadings for this section, as
necessary. THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY.
Evidence gaps and research question: (approx. 300-400 words)
Provide a conclusion that summarises your critical appraisal of these studies, highlighting any gaps
in the research evidence. Conclude with a specific research question that has arisen from your
review and appraisal of the literature. Your research question should be clear, concise and specific.
Provide a list of all articles referenced in the literature review. Refer to Week 2 lecture notes
regarding guidelines on appropriate referencing. Articles should be referenced using Vancouver
style – refer to the UQ Library Style Guide https://guides.library.uq.edu.au/referencing/vancouver

THE ASSOCIATION BETWEEN BREASTFEEDING AND OBESITY
Obesity is a public health challenge facing the world today. One of the most worrying
trends in the obesity pandemic is the rising case of childhood obesity. In the United States for
example, national data shows 8.9% of children aged between 2 and 5 years, and 20.5% of
adolescents between 12 and 19 years are obese (12). In developing countries, childhood obesity
has increased from 8.1% in 1980s to 12.9% in 2013 for boys and from 8.4% to 13.4% for girls
within the same period (12). Over the past three decades the prevalence of obesity has steadily
increased in developed and developing countries. Childhood obesity is a multifaceted condition
that has different causes and different health implications. Childhood obesity is caused by
genetic, environmental, and behavioural condition. While genetic factors are linked to likelihood
of developing obesity, environmental factors, especially food choices lack of physical activities
are among the contributing factors (11)………..
