Study Notes
Environmental Health Science
- A classic component of public health, responsible for much of the public health improvement in the US in the 20th century
- Environmental factors affecting health:
- Air quality
- Water quality
- Solid and hazardous wastes
- Safe food and drugs
- Global environmental issues
- Thousands of new chemicals enter the environment every year, with little known about their effects on human health
Social and Behavioral Sciences
- Behavioral factors are now the leading concern for people's health
- Theory of health behavior: social environment affects people's behavior
- Major health threats:
- Tobacco
- Poor diet
- Physical inactivity
- Injuries
- Disparities in health: Blacks have a lower overall life expectancy than whites, even with similar incomes
Health Policy and Management
- Examines the role of medical care in public health
- Issues in the US:
- High cost of medical care
- High percentage of population without health insurance
- Lack of access to medical care for the uninsured
- Questionable quality of medical care
- Medical care has diverted profits from education, housing, and the environment
Public Health Approach
- Primary prevention: prevents an illness or injury from occurring
- Secondary prevention: minimizes the severity of the disease or injury once it has occurred
- Tertiary prevention: minimizes disability by providing medical care and rehabilitation services
- Focus of public health: prevention of disease and disability, not just curing illness
Public Health: Science and Politics
- Science: understanding health threats, determining interventions, and evaluating their effectiveness
- Politics: making decisions about policies to implement
- Public health initiatives are funded by taxes
Public Health Disciplines
- Epidemiology
- Statistics
- Biomedical Sciences
- Environmental Health Science
- Social and Behavioral Sciences
- Health Policy and Management
Epidemiology
- The basic science of public health
- Studies epidemics, focusing on human populations and seeking common exposures and causes
- Epidemiologists work in local public health departments
Statistics
- Governments collect health data on populations, which are used as diagnostic tools for the community's health
- Statistical analysis is essential in epidemiological and clinical studies
Biomedical Sciences
- A major portion of human disease is caused by microorganisms
- Control of infectious diseases was a major public health focus in the 19th and early 20th centuries
Public Health History
- 19th century recording keeping began in England and Wales
- Death rates were high among children, with 2-3 of 10 newborns not reaching their first birthday
- Public health has improved significantly since the early 19th century
Definition of Public Health
- C.E.A Winslow (1920): "the science and the art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts"
- Institute of Medicine (1988): "fulfillment of society's interest in assuring the conditions in which people can be healthy"
Core Functions of Public Health
- Assessment: the diagnostic function of public health
- Policy development: using scientific knowledge to develop strategies to improve community health
- Assurance: ensuring access to services needed to protect the community
- The community is the patient in public health, not the individual
