CM1.1-10 | Foundations of Health, Disease and Prevention — Assignment

CLINICAL SCENARIO

You are a newly posted medical officer at a Primary Health Centre in a semi-urban district of India. The District Health Officer has asked you to submit a structured health analysis report for your PHC catchment area before the quarterly review meeting. This assignment requires you to apply the core concepts of public health — determinants of health, the epidemiological triad, natural history of disease, levels of prevention, and health indicators — to a real-world PHC context.

This task integrates your learning across CM1.1–CM1.8 and asks you to move beyond recall toward practical reasoning about population health.

Instructions

Write a structured report (approximately 1,200–1,500 words) addressing all five sections below. Use sub-headings to organise your response. Provide evidence-based reasoning — where you cite indicators, state the correct formula/denominator. Where you apply a framework (epidemiological triad, levels of prevention), explicitly label the components you are identifying. Use clear, professional prose appropriate for a district health review document.

Length: 1,200–1,500 words total across all five sections. Quality of reasoning matters more than word count.

What to Submit

Section 1: Public Health Framing (CM1.1–1.2)

In 2–3 paragraphs, explain how your role as a PHC Medical Officer differs from a hospital clinician's role using Winslow's definition of public health. Then identify three specific determinants of health (from at least two different determinant categories — biological, behavioural, socio-economic, environmental, or healthcare) that are likely to affect your catchment population, and justify why each is relevant to a semi-urban Indian PHC context.

Section 2: Disease Analysis Using the Epidemiological Triad (CM1.3)

Select ONE communicable disease (e.g., typhoid, malaria, dengue, or tuberculosis) common to your region. Using the epidemiological triad framework, systematically identify the key Agent, Host, and Environmental factors contributing to disease transmission in your catchment area. Then briefly describe the 'web of causation' perspective: how do these factors interact?

Section 3: Natural History and Levels of Prevention (CM1.4–1.5)

Using the same disease from Section 2: (a) Briefly outline the natural history of disease from prepathogenesis to outcome; (b) Identify ONE evidence-based intervention you would implement at each of the four levels of prevention (primordial, primary, secondary, tertiary) — state the level, the intervention, and its timing within the natural history; (c) Explain why identifying the subclinical (iceberg) phase matters for your PHC strategy.

Section 4: Health Indicators for Your District (CM1.7–1.8)

Your DHO asks you to interpret a district data table showing: IMR=45, NMR=28, MMR=200, TFR=2.8, CBR=24. (a) State the correct formula/denominator for each indicator. (b) Interpret this profile — which indicators concern you most and why? (c) Identify which national health programme(s) address the two most concerning indicators and name one specific target or strategy of each programme. Reference SRS as a data source.

Section 5: Health Communication Plan (CM1.6, CM1.9–1.10)

Design a brief IEC/BCC communication strategy to address ONE major health behaviour problem in your catchment area (e.g., low antenatal care uptake, poor oral rehydration therapy use, tobacco initiation in youth). Include: (a) target audience; (b) the specific behaviour change goal (KAP framing); (c) two communication channels and justification; (d) how you would use the teach-back method in an interpersonal counselling session for the same behaviour change. (150 words maximum for this section.)

Grading Rubric — Foundations of Health, Disease and Prevention — Assignment Rubric

Criterion	Points	Full-marks descriptor
Public health framing and determinants of health (Section 1) — Accuracy of Winslow's definition application and quality of determinant analysis	20 pts	Winslow's definition applied precisely and correctly to distinguish PHC MO role from clinician. Three determinants from ≥2 distinct categories identified with accurate labelling and convincing PHC-context justification. Population focus evident throughout.
Epidemiological triad analysis (Section 2) — Systematic identification of agent, host, and environmental factors; web of causation reasoning	20 pts	All three triad components correctly identified for the chosen disease with accurate, disease-specific content. Web of causation described with at least two factor interactions. Analysis is internally consistent and epidemiologically sound.
Natural history and levels of prevention integration (Section 3) — Correctness of natural history stages, appropriate level-intervention mapping, and iceberg rationale	25 pts	Natural history stages correctly identified in sequence for the chosen disease. All four prevention levels (primordial/primary/secondary/tertiary) mapped to appropriate interventions with correct stage labelling and natural history timing. Iceberg explanation is clinically and epidemiologically accurate.
Health indicator literacy and programme knowledge (Section 4) — Correct formulas/denominators, accurate interpretation, appropriate programme linkage	20 pts	All five indicator formulas/denominators stated correctly (IMR per 1,000 LB; NMR per 1,000 LB first 28 days; MMR per 100,000 LB; TFR lifetime births per woman; CBR per 1,000 mid-year population). Interpretation identifies the highest-concern indicators with sound reasoning. Two relevant national programmes named with a specific target or strategy. SRS referenced as data source.
IEC/BCC plan and teach-back application (Section 5) — Practical feasibility, KAP framing, channel justification, and correct teach-back description	15 pts	Clear and specific behaviour change goal stated in KAP terms. Two channels chosen with convincing PHC-context justification (reach, literacy appropriateness, cost). Teach-back described accurately as a two-way comprehension verification technique — not as patient education monologue. Within word limit.
