Health Promotion

1. What is Health?

  • Health: Overall state of well-being.

  • Illness: Personal experience of feeling unwell.

  • Disease: Specific pathological condition.

2. Health Promotion
Improving health and preventing illness.

  • Healthy eating

  • Exercise

  • Immunizations

  • Stress management

  • Regular screenings

  • Avoiding tobacco and excessive alcohol

  • Adequate sleep

3. Health Promotion Across the Lifespan

  • Major Life Stages:

    1. Infancy

    2. Early childhood

    3. Middle childhood

    4. Adolescence

    5. Young adulthood

    6. Middle adulthood

    7. Older adulthood

4. Determinants of Health
Factors influencing health:

  • Genetics/Biology: Inherited traits

  • Environment: Housing, pollution, safety

  • Lifestyle/Behavior: Diet, exercise, smoking

  • Healthcare Access: Quality and availability - social

  • Socioeconomic Factors: Income, education, employment - social

  • Social Support: Family, friends, community

  • Culture: Health beliefs and practices - social

  • Education: Health literacy - social

5. Prevention
Three Levels:

  • Primary: Prevents disease (e.g., vaccines, healthy diet)

  • Secondary: Early disease detection (e.g., screenings)

  • Tertiary: Manage existing disease (e.g., rehabilitation)

6. Wellness
An active choice process for better health across dimensions:

  • Physical

  • Emotional

  • Social

  • Intellectual

  • Spiritual

  • Environmental

  • Occupational

Quick Recall for Prevention:

  • 1° = STOP (Prevent before it starts)

  • 2° = SCREEN (Detect early)

  • 3° = SUPPORT (Manage and prevent complications)


Development: the pattern of movement or change that begins at conception and continues through the human life span (until death).

 Traditional Approach: emphasizes extensive change from birth to adolescence, little to no change in adulthood, and decline in old age(growth stops at adolescence)

Life Span Approach: Growth happens throughout life(changes).

  • Menopause

  • Frontal lobe

  • Dementia

  • Arthritis

Life expectancy - 79 years

Female longer - Body Comp, hormones, X chromosome.

Growth: quantifiable change in structure

  • Childhood: growth measured regularly

  • Adulthood: assess systems undergoing change

•Many factors impact and influence

Rate of development varies - all depends on factors and influences.

  • Cephalocaudal: head to toe

  • Proximodistal: midline to periphery

    • In to out

  • Differentiation: simple to complex; general to specific

    • Embryo and starts to grow.

  • Development involves growth, maintenance, and regulation of loss.

  • Development is a co-construction of biology, culture, and the individual.

  • Development is lifelong and multidimensional: biological, cognitive, and socioemotional dimensions.

Conceptions of Age

 

  • Chronological age: # of years alive

 

  • Biological age: age in terms of ones health

 

  • Psychological age: adaptive capacities compared to others of the same age


  • Social Age - connected with others better support group - live longer.


Biological: changes in an individual’s physical nature

  • physical changes

 

Cognitive: changes in thought, intelligence, and language

  • might learn diff language

  • Health literacy

  • Mental changes

 

Socioemotional: changes in relationships with other people, changes in emotions, and changes in personality.

  • relationships

  • All emotions

  • How you handle it

  • Interactions - how u interact with people(patients with attitudes)


Five Theoretical Orientations to Development 

Psychoanalytic 

Cognitive 

Behavioral and Social Cognitive

Ethological

Gilligan - Personal relationships. Empathy, responsibility, avoiding harm, emotions. Should be present everywhere. Relationships with patients is important no matter what. CAREGIVER TOO!

Erikson’s - highlights 8 psychological conflicts. Applied psych, but all nursing settings. Relate to time period. Worse and better option. Def pediatric nurse! Accomplishment vs conflict. Want them to accomplish goals.

Piaget - gain knowledge through world around them. Cognitive skills and logic.

Stage 1: Sensory motor (birth to 2)

Stage 2: Pre operation (2-7)

Stage 3:Concrete operational (7-11)

Stage 4: Formal operational(11-older)

Vygotsky - Social interaction. Outpatient

Kholberg - 6 stages (what’s right and wrong) Rules - reward system. Top - gain morals.

Theory - Roadmap. Guidance, blueprint. Promotion healthy habits for patients.

Health is core concept

•Epidemiology: study of health and disease from a societal perspective

Health viewed as dichotomy

  • High-level wellness vs depletion of health.

  • Wellness is the positive end of continuum.

  • Adaptation is the negative end of continuum.

Current views of health: Emphasis placed on quality of life. Nutrition.

Models of Health (Clinical, Role Performance, Adaptive)

  • being free from signs and sympotms of Disease.(Clinical)

  • Can they perform their roles? (Role)

  • Adjust positively to society(Adaptive)

•Eudaimonistic Model

  • Optimal health

    • Physcial, psychological, social, spiritual.

•Wellness-Illness Continuum

  • Positive health

•High-Level Wellness

  • Low level - ill

  • High - healthy.

Disease

  • failure of adaptive mechanisms.

  • Results in Functional structural disturbances

  • Multifactoral approach increases chance of successful intervention.

Ilness:

  • Subjective çeperince of individual and physical manifestation of Disease.

  • Mismatch en needs and resources to meet the needs.

  • When u start needing help.

Disease vs Illness- disease has no symptoms. Illness has symptoms but can’t see underlying disease. Both - symptoms and detection.

Disaprity - differences in how you treat them according to race,etc.

Primary Prevention:

  • Precedes disease/dysfunction

  • Interventions—health protection

  • Health promotion (e.g., education)

  • Vaccines are primary prevention interventions

  • Focus: maintain/improve general individual, family, community health

  • Health protection – reducing threats to health

  • Health promotion – encouraging lifestyle change to move toward health

Six Stages change: Transtheoretic model of change

  • Pre-contemplative—not considering change

  • Contemplative—aware but not considering change soon

  • Preparation—planning to change

  • Action—has begun to make behavioral change (recent)

  • Maintenance—continued commitment to behavior (long term)

  • Relapse—reverted to old behavior

Secondary Prevention:

  • Focus on early detection

  • Earlier treatment results in more favorable outcomes

  • Limit disabilities from disease

  • Screening falls under secondary prevention

    • Individuals

    • Populations

Examples: Colon cancer screening, Pap tests

Tertiary Pervention

  • Focus on restoration and rehabilitation

  • Minimize long term complications of disease

  • Restore function; prevent further injury/disease

Examples:

  • Cardiac rehab after myocardial infarction (MI)

  • ROM to maintain mobility after cerebrovascular accident (CVA)
