HSBH1012 · Introduction to Health and Health Care
The Social Determinants of Health
Week 4 of University of Sydney HSBH1012 is the conceptual heart of the unit: the social determinants of health — the conditions in which people are born, grow, live, work and age (WHO) — the “causes of the causes”, the upstream/downstream (river) model, the difference between equity and equality, individual versus structural responsibility, and Marmot's “lifestyle drift”. These ideas recur in almost every later week and are the most reflected-on in the exam. Its reading (Friel et al., 2015, on inequities in healthy eating) is a core exam-pool item.
What this chapter covers
- 01Determinant categories: genetic/biomedical, behavioural risk factors, and social determinants
- 02Social determinants of health (WHO): the conditions in which people are born, grow, live, work and age — predictable, measurable, shaped by the distribution of money, power and resources
- 03The five-domain wheel: Economic Stability, Education, Health Care, Neighborhood & Environment, Social & Community Context
- 04“Causes of the causes” (AIHW 2016): the social conditions that shape all other determinants (the 'postcode lottery')
- 05Upstream vs downstream (Zola's river): upstream = systems/context beyond individual control; downstream = individual choices within immediate control
- 06Equity vs equality: equity = fairness between differently-situated groups (sometimes different shares); equality = same shares/rates
- 07Responsibility and blame: attributing a health state to a behaviour makes a person 'blameworthy' and shapes which solutions seem justified
- 08Lifestyle drift (Marmot Review): upstream evidence sliding into downstream, individual-behaviour recommendations
Applied: classify initiatives as upstream or downstream and diagnose lifestyle drift
- +2(a) Upstream = systems, institutions and the background context of group life, not subject to any one person's choice (e.g. clean water, employment, housing) — needs policy/collective solutions. Downstream = individual choices in the immediate context (cook vs order-in, exercise, alcohol), within personal control but shaped by upstream conditions.
- +1(b)(i) Raising cigarette taxes = upstream (a structural/fiscal lever). (ii) Weight-loss incentive app = downstream (targets individual behaviour).
- +1(b)(iii) Banning soft-drink sales in schools = upstream (changes the environment/availability). (iv) Physical-activity awareness campaign = downstream (targets individual choice).
- +1(c) This is lifestyle drift (coined by the Marmot Review committee): findings that point to upstream targets end up producing downstream, individual-behaviour recommendations.
- +1(c cont.) Why it happens: tension between individual and collective attribution, liberal-democratic individual-choice values, and the fact that 'individual choice' interventions are cheaper for governments — physical activity gets framed as a 'best buy' even when the evidence points upstream.
Key terms
- Social determinants of health (SDoH)
- The conditions in which people are born, grow, live, work and age (WHO); predictable and measurable, shaped by the distribution of money, power and resources at global, national and local levels.
- Causes of the causes
- The social conditions (AIHW 2016) that are the single most important determinant of health because they shape all the other determinants — e.g. the 'postcode lottery', housing, socioeconomic status, employment.
- Upstream determinants
- Systems, institutions and the background context of group life — not within any one person's control (clean water, employment, housing). Require policy, systems and collective solutions.
- Downstream determinants
- Individual choices in the immediate context of action — within personal control (diet, exercise, alcohol) — but themselves shaped by upstream conditions.
- Equity vs equality
- Equity = fairness between differently-situated groups, which can mean giving different shares to reach sufficient health; equality = the same shares, rates or achievements for everyone.
- Lifestyle drift
- Coined by the Marmot Review committee: the tendency for policy that starts by identifying upstream targets to end up recommending downstream, individual-behaviour changes — because they are cheaper and fit individual-choice values.
The Social Determinants of Health FAQ
What are the social determinants of health?
The WHO defines them as the conditions in which people are born, grow, live, work and age. They are predictable and measurable, interact with (but are distinct from) genetic and behavioural factors, and are shaped by how money, power and resources are distributed. AIHW calls them the 'causes of the causes' because they shape all the other determinants of health — which is why they run through the entire unit and the exam.
What is the difference between upstream and downstream, and between equity and equality?
Upstream determinants are structural — systems and context beyond any individual's control (housing, employment, clean water) — and need collective/policy solutions; downstream determinants are individual choices (diet, exercise), within personal control but shaped by upstream conditions. Equity is fairness between differently-situated groups (sometimes different shares to reach sufficient health), whereas equality means the same shares for everyone. Confusing the two is a common exam slip.
What is lifestyle drift?
Lifestyle drift, from the Marmot Review committee, describes what happens when policy or research that identifies upstream causes of poor health nonetheless ends up recommending downstream, individual-behaviour changes. It is driven by the tension between collective and individual attribution, liberal-democratic individual-choice values, and the fact that individual interventions are cheaper for governments. Spotting lifestyle drift in a scenario is a classic Week 4 question.
Can AI help me with the social determinants of health?
Yes. Sia can explain the upstream/downstream river, drill you on equity versus equality, help you classify real initiatives, and coach a practice reflection on Friel et al. (2015) against the exam rubric. It explains the reasoning step by step and checks your answers; it does not write your graded reflection or SAQ. Confirm assessment details on Canvas.
Exam move
This is the highest-yield week for the exam, so over-invest here. Be able to define the social determinants verbatim (the WHO 'born, grow, live, work and age' phrasing), draw the upstream/downstream river from memory, and separate equity from equality with an example. Drill the classifier until it is instant — given any initiative, decide upstream or downstream — and always be ready to name and explain lifestyle drift when a scenario shows a mismatch between diagnosis and policy. Draft a full reflection on Friel et al. (2015) now, linking the reading to Zola's river and Marmot; it is one of the most likely exam-pool readings. Ask Sia to sort initiatives with you and grade your reflection on the 60/20/20 rubric.
