Assignment Requirements 

  1. Utilizing the list below, choose two research methods.
  2. Next, find two articles, one on each of the chosen methods, from the Chamberlain College library, or you may use one that is provided within the course and one you find from the library. The articles should be related to population health and infectious disease, chronic health, occupational health, global health, genomics, or environmental health:
    • Randomized Control Trial
    • Cohort Study
    • Case-Control Study
    • Cross-Sectional
    • The articles you choose should be completely in English (this includes the reference list). They should be related to population health and speak to one of the following elements from the course: Infectious disease, chronic health, occupational health, global health, genomics or environmental health.
  3. Read each article and answer the following questions with detail for each article, include succinct definitions/examples or rationale as fitting to the question. Organize your answers using the number of the question you are answering (1-8). Your answers should provide more than a “yes” or “no”, your answers should provide examples, critical thinking, definitions, and examples.
    1. Does the study design specify a question, goal, of the study?  Why is this important?
    2. Explain the methodology (Randomized Control Trial, Cohort Study, Case-Control Study).
    3. Describe the participant information, include recruitment. Is selection bias present?
    4. How is data collected?
    5. Are the variables identified? If yes, discuss. If no, how does this impact your interpretation of the study?
    6. How was the data analyzed, what statistics are provided? What are potential errors related to the study design?
    7. What are the weaknesses of the type of study design/method?
    8. Discuss the outcomes and the implications for implementation.
  • Post your analysis of the research studies to the DB. Your analysis should have in-text citations and utilize a scholarly voice with APA formatting. You may choose to write a Word doc and upload your doc to the discussion board for this week.

Solution:

Randomized Control Trial

 Article 1: Bjornstad, P., Schäfer, M., Truong, U., Cree-Green, M., Pyle, L., Baumgartner, A., … & Nadeau, K. J. (2018). Metformin improves insulin sensitivity and vascular health in youth with type 1 diabetes mellitus: A randomized controlled trial. Circulation, 138(25), 2895-2907. https://doi.org/10.1161/CIRCULATIONAHA.118.035525

  1. The study has clearly stated the goal of the study. The goal of the study was to examine if the use of Metformin in adolescents with type 1 diabetes mellitus (T1DM) improves insulin resistance. The importance of a clear goal is that it informs the readers on the specific aims of the research and prevent the issue of struggling to determine the focus of the study.
