Study Notes
Basic Concepts of Health and Disease
- Health is a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity.
- Disease is a condition characterized by an interruption, cessation, or disorder of body functions, systems, or organs, typically evidenced by specific symptoms.
- Illness is the individual's experience of being unwell. It encompasses subjective feelings and perceptions, and is not necessarily associated with identifiable disease.
- The agent-host-environment model describes disease etiology. Agents are harmful factors (bacteria, viruses), hosts are susceptible individuals, and the environment provides context.
- The epidemiological triad is a model of disease causation. It identifies environmental factors, host factors, and agents involved in disease transmission.
- Risk factors are characteristics or behaviors that increase the likelihood of developing a disease or injury.
National Health Policies and Health Programs
- National health policies are sets of strategies and plans that are implemented by governments to address health issues within the population. These policies encompass various levels.
- These policies and programs aim to achieve health goals, such as reducing mortality, increasing life expectancy, and improving the overall quality of health.
- Key objectives of national health policies often include:
- Achieving health equity for all citizens or residents.
- Promoting preventative care and healthy public policy.
- Increasing access to quality primary healthcare.
- Ensuring quality medical care standards.
- Improving public health infrastructure.
- Health programs are specific initiatives designed to improve health or address a particular disease or problem in specific populations. They are often a subset of broader national health policies, and their implementation is often guided by research and evaluation.
- Implementation of national health policies and programs varies significantly across different nations. Factors like economic resources, political will, social norms, and cultural beliefs influence effective implementation.
- Examples of national health programs might include:
- Vaccination programs for childhood illnesses,
- Screening programs or early detection efforts for cancers or diabetes,
- Public awareness campaigns for injury prevention.
- Addressing chronic diseases like heart disease and stroke.
- Initiatives to improve access to clean water and sanitation.
- Evaluation of program effectiveness is crucial. Program performance is assessed to improve results and accountability. This includes monitoring key indicators, evaluating costs benefit outcomes and making informed decisions for future implementation.
- Cost-effectiveness of national health programs is a key consideration, balancing resources with health benefits and long-term impacts.
