Week 1

Concepts of Health

• Hippocrates, considered the "Father of Medicine," was renowned for his kindness, concern, and love for the art of healing.
• Medical knowledge has evolved through theories, misinformation, inventions, and discoveries.
• Observational and cumulative experiences have been key to medical advancements.
• Throughout history, people have sought to control disease, relying on various methods (medicine men, priests, herbolists, and magicians).
• Communities define health differently based on culture, but it is often neglected.
• Health at the individual level is frequently subjugated to seemingly more important factors like power, prestige, wealth, knowledge, and security.
• Health often perceived as 'absence of disease"
• Health isn't just the absence of disease, but a balance with one's surroundings and environment.
• Maintaining healthy habits, like exercise, rest, hygiene, diet, mental well-being, and social skills contributes to health.

Changing Concepts of Health

• Biomedical Concept: Historically, health was viewed as the absence of disease. This concept, however, is insufficient to understand the complex nature of health issues like malnutrition, chronic diseases, and accidents.
• Ecological Concept: Health is considered a dynamic equilibrium between individuals and their environments; poor adaptation leads to illness.
• Psychosocial Concept: Health is influenced by social, psychological, cultural, economic, and political factors.
• Holistic Concept: This approach considers the influence of all societal sectors on health, including agriculture, food, industry, education and the overall environment.

Dimensions of Health

• WHO: Defines health as encompassing the physical, mental, and social dimensions (among other aspects like spiritual, emotional, vocational and political).
• Physical Dimension: Perfect functioning of the body's cells and organs, measured by community-level metrics (e.g. mortality rates, infant mortality rate, life expectancy).
• Mental Dimension: A harmonious internal balance between the individual and the surrounding environment and between oneself and others. This is assessed through questionnaires.
• Social Dimension: Quality and quantity of interpersonal relationships, community involvement, and integration within society.

Other Dimensions of Health

• Spiritual Dimension: Integrity, principles, ethics, purpose, higher being, and beliefs.
• Emotional Dimension: Closely linked to mental health with feelings and cognition.
• Other dimensions suggested include vocational, philosophical, cultural, socioeconomic, environmental, educational, nutritional and preventive aspects.
