Health, Determinants & Prevention

Understand how living conditions, disease processes and prevention shape the health of a population.

FULL CHAPTER EXPLANATION

Deep Learning — Module 01

Connect population needs and measurements to prevention, practical action and evaluation.

01

Health and its dimensions

Health includes physical functioning, mental wellbeing and social participation; absence of a named disease is only one part of assessment. A person living with a chronic condition can still improve function and wellbeing. Community medicine considers the distribution of these outcomes across groups. Measure both illness and positive functioning, and ask whose experience is missing from the available data before declaring a community healthy.

02

Determinants and equity

Income, education, housing, work, discrimination, transport and access to services influence exposure and the ability to seek care. Behavioral choices occur within these conditions. Equality supplies the same resource to everyone; equity addresses avoidable, unfair differences in opportunity and need. A clinic that is free but unreachable may leave an important inequity unresolved. Describe structural barriers rather than blaming a population for its disease burden.

03

Disease causation

The agent-host-environment model organizes infectious risks, but many diseases arise through interacting biological, environmental and social pathways. A risk factor can be associated with disease without being its sole cause. Genetic susceptibility does not imply inevitability. Natural history follows susceptibility, subclinical change, clinical disease and possible recovery, disability or death; interventions can alter this course at different stages.

04

Levels of prevention

Primordial prevention limits the emergence of harmful conditions, such as designing communities that support activity. Primary prevention acts before disease begins, for example immunization. Secondary prevention detects and treats early disease, such as an evidence-based screening programme with follow-up. Tertiary prevention reduces established disease complications and disability, including rehabilitation. Classify the intervention by its objective and the disease stage, not by the profession delivering it.

05

Population strategy

A high-risk strategy targets people with greater individual risk; a population strategy changes exposures across society. They are complementary: safe food policy can operate alongside individual hypertension care. Control reduces disease burden, elimination addresses a specified disease target in a defined area, and eradication concerns worldwide interruption of the specified infection. State the target precisely; elimination as a public-health problem does not necessarily mean zero transmission.

High-Yield Revision

  • Distinguish equal provision from equitable access.
  • Prevention level depends on disease stage and purpose.
  • Association alone does not establish causation.

Common Exam & Concept Pitfalls

  • Do not reduce health to the absence of a diagnosis.
  • Do not equate elimination as a public-health problem with eradication.
