Study Notes
Concept of Health and Disease
- Health has multiple definitions based on perspectives: absence of disease, normal anatomical structures, physiological functions, biochemical levels, and psychological balance.
- WHO defines health as a state of complete physical, mental, and social well-being, not just absence of disease.
Dimensions of Health
- Physical Health: Indicators include appropriate body weight, vital signs, and alignment with developmental standards.
- Mental Health: Encompasses positive well-being, coping abilities, productivity, and healthy social interactions.
- Social Well-being: Involves interpersonal relationships, societal roles, and community interactions influenced by socioeconomic factors such as income and literacy.
Determinants of Health
- Heredity: Genetic predispositions affecting health.
- Environment: Both natural and man-made factors impacting health, including housing and urban infrastructure.
- Health Services: Accessibility and quality of health care are crucial.
- Behavior: Personal habits, choices, and lifestyle practices affecting health outcomes.
Health Indicators
- Defined by community measures such as economic status, life expectancy, and mortality rates.
- A healthy community has low disease rates, good environmental conditions, and accessible health resources.
- Rural health parameters include sanitation, clean water, literacy, and skilled maternal care.
Understanding Disease
- Disease is characterized as "without ease," relating to physiological or psychological problems.
- Illness: Encompasses individual perceptions and social dysfunction related to disease.
Environmental Factors Related to Disease
- Physical Environment: Includes air quality, water, and radiation.
- Biological Environment: Focuses on disease vectors and infectious agents present in specific areas.
- Social Environment: Encompasses socioeconomic status, customs, and beliefs affecting health.
Natural History of Disease
- Describes disease progression over time, renowned for chronic and insidious onset.
-
Stages of Disease:
- Susceptibility: Risk factors present; person is asymptomatic.
- Pre-symptomatic: Biological changes occur; still no clinical symptoms.
- Clinical Disease: Symptoms manifest and can be graded for severity.
- Termination: Outcomes include resolution, sequelae, or death.
- Sequelae: Residual effects of disease, leading to potential impairment.
Impairment, Disability, and Handicap
- Impairment: Loss or abnormality in function or structure; can be visible or invisible, temporary or permanent.
- Disability: Restriction in activity performance; may affect daily living.
- Handicap: Social disadvantages arising from disability that limits normal role fulfillment based on various factors.
Sequence of Health Events
- Disease leads to impairment, which may result in disability and ultimately a handicap.
- Example progression: An accident causing foot loss (disease) → inability to walk (disability) → difficulty in maintaining employment (handicap).
Dimension and Determinants of Health
- Health is a complex concept encompassing various aspects, not just the absence of disease.
- Different perspectives define health uniquely: anatomists focus on anatomical structures, physiologists on body functions, biochemists on biochemical levels, and clinicians on structural and functional abnormalities.
- Mental health is emphasized as achieving personal abilities, coping with life stresses, and contributing to society.
- Social well-being involves an individual’s ability to interact effectively within society, shaped by income level, literacy, occupation, and social relationships.
- Determinants of health include heredity, environment, health services, and behavior, influencing individual and community health.
Definition of Health
- WHO defines health as complete physical, mental, and social well-being rather than merely the absence of disease.
- Physical health involves measurements aligned with age and sex, including weight, height, and vital signs, indicating normal body functions.
- Mental health encompasses the ability to manage stress, maintain relationships, and contribute to one’s community effectively.
- Social health refers to adjusting and interacting with others positively, based on socio-economic factors.
Determinants of Health
- Heredity: Genetic factors influencing health.
-
Environment: The physical and social surroundings significantly impact health. Includes:
- Man-made environment: Housing, transport, and communication.
- Health Services: Access to, affordability of, and acceptance of health care services.
- Behavior: Lifestyle choices, habits, actions, beliefs, and attitudes impacting health.
Community Health
- Community health is measured through economic indicators, life expectancy, mortality rates, literacy, and overall health resources.
- A healthy community shows low disease and death rates, access to healthcare, sound environmental conditions, high literacy rates, and overall quality of life.
- Specific indicators for a healthy village include clean water supply, waste disposal, good housing conditions, and high female literacy.
Concept of Disease
- Disease signifies "uneasiness" and can be a physiological or psychological dysfunction.
- Illness encompasses individual perceptions and behaviors related to disease, indicating a subjective experience.
- Sickness refers to the social consequences of being ill and the roles assumed during illness.
Environmental Factors Related to Disease
- Physical Environment: Includes air, water, light, heat, and radiation which can affect health.
- Biological Environment: Refers to agents causing diseases, including infectious organisms and vectors, influenced by the local ecological conditions.
- Social Environment: Encompasses socio-economic status, cultural beliefs, and traditional practices that impact health outcomes.
Natural History of Disease
- The natural progression of diseases involves several stages from susceptibility to termination.
-
Stages of Disease Development:
- Susceptibility: Risk factors present without clinical disease.
- Pre-symptomatic Disease: Initial biological changes before symptoms develop.
- Clinical Disease: Clear signs and symptoms occur; can be categorized by severity.
- Termination: Outcomes include resolution, progression with effects, or death.
- Sequelae: Aftermath of disease that may result in permanent impairment.
Impairment, Disability, and Handicap
- Impairment: Loss or abnormal function of a body part or system.
- Disability: The impact of impairment on an individual's ability to perform tasks.
- Handicap: The disadvantage experienced due to impairment or disability in societal contexts.
