Here is your complete scaffolded guide to writing a literature review on social determinants of health.--- ## Step 1 — Define the scope **What a literature review is (and isn't)** A literature review is not a book report, an annotated bibliography, or a collection of summaries stapled together. It's an argument about a body of research — your way of showing that you understand not just what individual scholars have said, but how their work relates to each other and to your paper's larger purpose. Because this lit review is a *section* of a larger research paper, its job is even more specific: it needs to set up your paper's rationale. That means establishing what is already known about social determinants of health, identifying where debates or uncertainties exist, and positioning your own paper as a meaningful contribution to that conversation. **The core distinction: summarizing vs. synthesizing** Summarizing means reporting what one source says. Synthesizing means showing how multiple sources speak to the same question — where they agree, disagree, build on each other, or leave something unresolved. Upper-division work requires synthesis. A useful mental test: if each paragraph of your draft could be labeled with a single source's name, you're still summarizing. If each paragraph is labeled with an *idea*, you're synthesizing. **The key intellectual task for this topic and discipline** SDOH is a richly interdisciplinary field that draws on epidemiology, sociology, health policy, and community health. Your core task is to map the conceptual and empirical landscape of the field as it applies to your paper's argument — demonstrating that you understand not just individual findings, but the frameworks, debates, and evidence gaps that give those findings meaning. --- ## Step 2 — Map the structure **Recommended organizational approach: thematic** A thematic structure is the strongest choice for this topic. Social determinants of health — income, housing, education, race, neighborhood, food access, and more — naturally cluster into conceptual categories that researchers investigate somewhat independently, even as they argue for their interconnection. Organizing thematically lets you show how each category of determinant has its own evidence base, contested claims, and methodological debates, while also connecting them under the umbrella of structural drivers of health inequity. A chronological approach could work if your paper traces the historical development of SDOH policy or research (e.g., post-Lalonde, pre- and post-ACA), but it risks becoming a history lesson rather than an analytical framework. A methodological approach (grouping quantitative vs. qualitative work) could support a paper focused on research design gaps, but it's rarely the primary structure at this level. **Your organizational rationale going forward:** As you read, ask yourself: *What is this source primarily arguing, and what driver of health does it center?* That question will help you assign each source to a theme. Expect your themes to shift slightly as your reading deepens — that's normal and healthy. --- ## Step 3 — Build the scaffolding ### Stage 1 — Search and collect **Best databases for this topic:** Public health literature lives in a handful of key places. Start with PubMed/MEDLINE for peer-reviewed health and epidemiological research. Add JSTOR and Sociological Abstracts for the sociological and theoretical dimensions of SDOH. The WHO Global Health Library and CDC's public health database are excellent for policy documents and reports. Google Scholar is useful for finding grey literature and tracing citations. For health equity specifically, the Robert Wood Johnson Foundation and the Commonwealth Fund publish influential non-academic reports worth including. **Source types to prioritize:** peer-reviewed journal articles (especially systematic reviews and meta-analyses), government and intergovernmental health reports (WHO Commission on Social Determinants of Health is foundational), and influential theoretical frameworks (Marmot, Link & Phelan, Dahlgren & Whitehead). **Realistic gathering target:** Collect 25–30 sources before narrowing to your final 15. This gives you room to find that some sources are tangential, methodologically weak for your purpose, or redundant. Narrowing from a stronger pool produces a tighter, better-argued review. **Useful search terms:** "social determinants of health," "health inequity," "health disparities," "structural racism and health," "neighborhood health effects," "income and health outcomes" — combined with your paper's more specific focus. --- ### Stage 2 — Read and annotate At the upper-division level, you don't need to read every source from cover to cover before taking notes. Read strategically: Start with the abstract and conclusion to determine whether the source is genuinely relevant. Then focus on the introduction (what question is being asked and why), the methods section (what kind of evidence does this produce?), the results or findings, and the discussion/conclusion (what do the authors claim, and what do they acknowledge as limitations?). **Take notes that support synthesis, not just summary.** For each source, record: the core argument in one sentence; the type of evidence used (quantitative, qualitative, mixed methods, systematic review, theoretical); the population and context studied; one to two key findings; and crucially, what the authors say is *missing* or unresolved. That last item is often buried in the limitations section and is pure gold for your review. Keep a simple spreadsheet or table with these fields for all 25–30 sources. You'll thank yourself in Stage 3. --- ### Stage 3 — Identify themes and patterns Once you've read and annotated, spread your source notes out and look for groupings. For SDOH, common thematic clusters include economic determinants (income, poverty, employment), physical environment (housing, neighborhood, food access), social and community context (social support, discrimination, racism), health systems access, and early life conditions (education, childhood adversity). You're looking for sources that are asking similar questions, even if they reach different answers. Group them accordingly. Don't force a source into a theme — if it keeps resisting your categories, it may belong in multiple themes or may signal that you need a new one. Also note: which themes have abundant, rigorous evidence? Which are thinner? Which are almost entirely theoretical? That landscape will shape how you write each thematic section. --- ### Stage 4 — Map the conversation This is the intellectual core of your literature review. For each theme, identify three things: **Agreements:** What do most researchers in this area concur on? These represent the established knowledge base your paper can build from. Example: there is broad consensus that income is one of the strongest predictors of health outcomes. **Contradictions or debates:** Where do researchers disagree — in their findings, their explanations, or their methods? In SDOH, common debates include the relative weight of individual vs. structural factors, the mechanisms linking poverty and health, and whether specific policy interventions translate to health improvements. **Gaps:** What hasn't been studied, or studied adequately? Who is missing from the research (particular populations, geographies, or intersectional identities)? What methodological limitations are repeatedly acknowledged? **Why gaps are especially valuable:** In a research paper, a well-identified gap is the opening for your own contribution. You're not just reporting what others have done — you're showing your reader why your paper exists. A gap in the literature is your invitation. --- ### Stage 5 — Draft by theme The most common mistake at this stage is reverting to source-by-source summaries. Fight this instinct. Each paragraph in your literature review should be organized around an *idea*, not a source. Start with a topic sentence that makes a claim about the literature ("Research on housing instability consistently demonstrates a direct relationship with adverse mental health outcomes, though findings diverge on mechanisms and population specificity"). Then bring in multiple sources as evidence for, against, or nuancing that claim. A useful pattern: introduce the consensus, introduce a complication or counterpoint, and close with what remains unresolved or contested. Each paragraph should move *between* sources rather than staying with one. Write one thematic section at a time. Don't try to draft the whole thing at once. Two or three well-synthesized paragraphs per theme, with smooth transitions between themes, is a strong target. --- ### Stage 6 — Revise for coherence A strong upper-division literature review reads as a unified argument, not a tour of sources. Signs of strength: each thematic section has a clear controlling idea; transitions between sections explain how the themes relate to each other; the review builds toward the gap or rationale that motivates your paper. **Common structural problems to look for in revision:** Does your introduction tell the reader what the review will argue and how it's organized? Does your conclusion synthesize the state of the field — not just list what you covered — and point clearly toward your paper's contribution? Are your in-text citations doing work (attributing claims and findings accurately) rather than appearing decoratively? Is every source you cite actually present in your reference list? **The most common citation mistakes at this level:** over-relying on a single source to represent an entire body of literature; citing sources you haven't actually read in full; and failing to distinguish between primary research and secondary summaries of it. --- ## Step 4 — Flag common mistakes Three mistakes public health students frequently make in literature reviews at the upper-division level: **1. The annotation dump.** Writing the review as a series of paragraph-long summaries, one source at a time, rather than grouping sources by idea. *Correction: Organize every paragraph around a claim about the literature, not a report on a single article.* **2. Ignoring methodological diversity.** Treating a randomized controlled trial and an ethnographic study as if they produce equivalent and interchangeable evidence. *Correction: Note the type of evidence each source provides and acknowledge what that means for the strength and generalizability of its claims.* **3. Missing intersectionality.** Treating each social determinant as a standalone variable rather than examining how race, income, housing, and neighborhood interact and compound each other. *Correction: Actively look for sources that address overlapping determinants and make intersectionality part of your synthesis, not an afterthought.* --- You've got a clear path forward from first search to final revision.
