Study Notes on Health In The 21st Century

Life Expectancy and Health in the U.S.

  • The current life expectancy at birth in the United States is 78.8 years.
  • Major causes of death: heart disease and cancer account for nearly half.
  • Key factors linked to premature death include:
    • Poor nutrition
    • Inadequate physical activity
    • Obesity
    • Tobacco use
    • Alcohol abuse

Learning Outcomes

  1. Discuss the evolution of current understanding of health.
  2. Identify and describe seven dimensions of health.
  3. Discuss health challenges in America and globally.
  4. Classify health determinants into six groups and discuss control.
  5. Explain behavior change factors: predisposing, enabling, reinforcing.
  6. Compare three models of behavior change.
  7. List steps for successful behavior change and relapse prevention strategies.

Definitions

  • Health: More than absence of disease; a state of well-being involving physical, social, and psychological dimensions.
  • Disease: Alteration in body structure/biochemistry causing regulatory failures.
  • Illness: Subjective feeling of being unwell, disease may or may not be present.
  • Signs and Symptoms:
    • Signs: Visible/measurable indicators of disease.
    • Symptoms: Subjective experiences indicating disease.

Evolution of Health Understanding

  • Historically, health was understood as the absence of disease.
  • In 1948, WHO defined health as complete physical, mental, and social well-being.
  • Wellness: Defined by Halbert Dunn in 1959 as an active process of making choices for a successful existence.

Seven Dimensions of Health

  1. Physical Health: Functionality and care for the body.
  2. Intellectual Health: Openness to new experiences and critical thinking.
  3. Psychological Health: Self-acceptance, emotional regulation, and relationship nurturing.
  4. Spiritual Health: Sense of meaning and connection to greater values or beliefs.
  5. Social Health: Quality of relationships and social interactions.
  6. Environmental Health: Quality of surrounding environments affecting health.
  7. Occupational Health: Quality of relationship to one's work or studies.

Current Health Challenges in America

  • Life expectancy increased to 78.8 years; however, chronic diseases dominate mortality.
  • Top five causes of death in the U.S. include:
    1. Heart disease
    2. Cancer
    3. Chronic lower respiratory disease
    4. Accidents/unintentional injuries
    5. Stroke
  • Chronic disease prevention: Lack of physical activity, poor nutrition, tobacco use, excessive alcohol consumption.

Determinants of Health

  • Six categories:
    1. Biology and Genetics
    2. Individual Behaviors
    3. Social Determinants
    4. Physical Determinants
    5. Health Services
    6. Policy-Making

Factors Affecting Behavior Change

  • Predisposing Factors: Knowledge, beliefs, attitudes previously held.
  • Enabling Factors: Resources and skills facilitating change (e.g., access to health services).
  • Reinforcing Factors: Encouragement or rewards that enhance commitment to change.

Models of Behavior Change

  1. Transtheoretical Model (Stages of Change):
    • Precontemplation → Contemplation → Preparation → Action → Maintenance → Termination
  2. Health Belief Model: Predicts change based on perceived threat, severity, benefit, and cues to action.
  3. Ecological Models: Focus on multiple levels of influence, including societal impacts on behavior.

Steps for Successful Behavior Change

  1. Get Informed: Gather information about the change.
  2. Set a SMART Goal: Specific, Measurable, Attainable, Relevant, Time-based.
  3. Make a Plan: Day-to-day actions to achieve your goal.
  4. Identify Barriers and Solutions: Anticipate and strategize for obstacles.
  5. Recruit Support: Involve family and friends for accountability.
  6. Promise Rewards: Provide incentives for reaching milestones.
  7. Commit in Writing: Document change commitment for motivation.

Preventing Relapse

  • Recognize that lapses are common;
  • Use strategies like cue control (changing prompts for behavior) and counter-conditioning (replacing unwanted behaviors with healthier ones).

Advocacy and Health Equity

  • Engage in advocacy to address barriers from poor health services or policy-making.
  • Aim for health equity across diverse populations by eliminating disparities.

Conclusion

  • Today's health management and understanding integrate historical insights with an emphasis on community resources, personal behavior adjustments, and social equity principles to promote overall wellness.
