Questions and Answers

According to the World Health Organisation, what is the most accurate definition of 'health'?

Study Notes

Stage 4 Pathology - Pre-Module Learning

  • Health Definition: According to the World Health Organisation (WHO), health is a state of complete physical, mental, and social well-being, not just the absence of disease.
  • Disease Definition: An abnormal condition affecting the body's structure or function. Often associated with specific signs and symptoms.
  • Signs: Observable or measurable indicators of a condition (e.g., fever, rash).
  • Symptoms: Subjective experiences reported by the patient (e.g., pain, nausea).
  • Normality in Medicine: "Normal" is context-dependent in clinical practice. Typically correlated with the understood health status, but it has no singular meaning.
  • Normality Approach: Absence of pathological conditions may imply normality. Biostatistical Theory and a naturalist approach suggest this.
  • Statistical Viewpoint: Normality correlates to the frequency of a given condition in a population.
  • Gaussian/Bell Curve: Health indicators often follow a normal distribution in a population. The curve is bell-shaped and symmetrical.
  • Statistical parameters and a small dataset can estimate the behaviour of a large one.
  • Mean Value: Central point on the bell curve; the average value.
  • Standard Deviation: Measures the spread of data around the mean. 68% falls within +1 and -1 standard deviation from the mean.

Health Data and Concepts of Measuring Disease

  • Health Services: Planning and review are necessary to understand health problems in populations and implement future changes.
  • Health Variations: Populations show significant variations, and health assessment should be done in groups (socio-economic, geographic).
  • Population Data (Census): Counts of all people and households in a country. Provides population data from national to neighbourhood levels for government and communities.
  • Mortality Data: Statistics tracking death counts by age, cause, and time period. Compulsory registration of deaths has been in place since 1874.

Morbidity Data

  • Impact of Disease: Data that reveals the effects (pain, disability), spread, and increase of diseases across specific population groups.
  • Hospital Data (HAA): Hospital Activity Analysis records hospital admissions (excluding maternity and mental illness).
  • Hospital Data (IPE): Hospital Inpatient Enquiry (IPE) is a computer system to collect administrative, demographic, and clinical discharge statistics.
  • Annual Hospital Returns (SH3): Information about daily ward activities, including patients with specific conditions (e.g., diabetes).
  • Mental Health Enquiry: Data on psychiatric inpatients.
  • Community Data: Population-level health data. May include general household surveys & specific disease rates

Measuring Disease

  • Rate Components: The rate of disease considers the number of people experiencing a specific disease (numerator), the total population in the relevant group (denominator), and the relevant period (time) for calculations.
  • Crude Rate: A measure of disease (deaths or births) across the total population.
  • Specific Rate: A rate focusing on specific subgroups (age, sex, race) within a population.
  • Mortality Rate: Shows deaths within particular groups.

Incidence and Prevalence

  • Incidence: Number of new cases of a disease within a population for a specific time period.
  • Prevalence: The total number of existing cases of a disease within a population at a given point in time.
  • Global Health Risks: The WHO report identifies the top 10 global risk factors, globally and regionally. Underweight, unsafe sex, high blood pressure, tobacco use, and alcohol consumption are among them, as are issues like unsafe water, sanitation, hygiene, iron deficiency, indoor smoke, and excessive cholesterol.
