Literature analysis

Article link https://www.annualreviews.org/doi/full/10.1146/annurev-publhealth-031210-101218
While reading your selected article, consider some of the following questions to help guide your summary:
a. Why, according to the authors, is this issue important?
b. Why, theoretically, do we expect a relationship between your selected X and Y?
c. What do we already know about this topic and what is left to discover?
Next write up your analysis of the literature focusing in three separate paragraphs on: a) why we expect a theoretical relationship between X and Y, b) what previous studies have found (including the authors of the article if they conducted original research), and c) what future research should consider.  You do not need an introduction or conclusion, but each of your three paragraphs should start with a topical sentence; I expect part a and b will take up most of your analysis. Your analysis should be a minimum of two double-spaced pages and a maximum of four.
