01Disease frequency, study design and causal interpretation
Epidemiology connects a defined population, an observation period and a health event. Incidence counts new events among people at risk, whereas prevalence describes existing cases at a specified time or period.
372 words, about 2 min02Variation, inference and screening calculations
Begin statistical interpretation with the type of variable, sampling process and unit of analysis. A nominal category has no inherent order; an ordinal scale has order without necessarily equal spacing.
373 words, about 2 min03Environmental pathways, water and air
Environmental health follows a source through an exposure pathway to a person or population. A hazardous substance in soil does not by itself establish a harmful absorbed dose.
360 words, about 2 min04Workplace hazards and prevention priorities
Occupational health begins with the actual task rather than a job title alone. Identify substances, dusts, biological agents, energy sources, repetition, load, work organization and the people exposed.
364 words, about 2 min05Nutrition assessment and foodborne hazards
Nutrition assessment combines intake, growth or body composition, clinical findings, laboratory evidence and the person’s circumstances. A food-frequency history and a biochemical marker measure different aspects of nutrition.
371 words, about 2 min06Dose, biotransformation and risk assessment
Toxicology relates an agent, dose, route, duration and host conditions to an effect. Hazard identifies the capacity to cause harm, whereas risk considers the exposure circumstances and probability or severity of that harm.
374 words, about 2 min07Surveillance, outbreak response and immunization
Public-health surveillance systematically collects, analyzes and interprets information to support action. A case definition standardizes who is counted using relevant clinical or laboratory features and time, place or person criteria.
373 words, about 2 min08Life-course prevention, equity and programme evaluation
Health promotion considers the conditions that allow people to act on health information. Knowledge can be necessary without being sufficient: cost, housing, work, language, access, discrimination and social support can constrain choices.
