    Study Notes

    Biopsychosocial Model of Health

    • Health is influenced by biological, psychological, and social factors.
    • Stress is a physiological response to perceived taxing events.
    • Factors contributing to stress include uncertainty, lack of control, and concerns over evaluation by others.

    General Adaptation Syndrome

    • Alarm Stage: Initiates "fight or flight" response; increased heart rate, sweating, and hormone release.
    • Resistance Stage: Enhanced cardiovascular and immune function; temporary high stress resistance.
    • Exhaustion Stage: Can lead to weakened immune system and inability to adapt to ongoing stressors; drastic decline in stress resistance.

    Stress and Health Disparities

    • Health disparities are influenced by demographic factors such as socioeconomic status (SES).
    • Higher SES correlates with better health outcomes due to better access to resources.
    • Individuals with lower perceived SES report negative emotions, higher resting heart rates, and greater obesity risks.

    Health Psychology Overview

    • Health psychology examines psychological and behavioral processes in health and illness.
    • Developed over the past 50 years, incorporating psychological, social, and environmental factors.
    • Investigates risk behaviors and personality traits affecting health.
    • Shift in leading causes of death; modern lifestyle affects health outcomes.
    • Behavioral science is crucial in public health, influencing initiatives like vaccination.

    The Biopsychosocial Model in Practice

    • It targets multiple factors influencing health, allowing for comprehensive health promotion and disease prevention.
    • Example: Smoking behavior is influenced by biological addiction, psychological rationalizations, and social norms.

    Integration in Healthcare

    • Increasing recognition of integrating biopsychosocial perspectives in medical education.
    • Behavioral and social sciences are now part of medical training assessments (MCAT).

    Stress Concepts

    • Stress: A subjective appraisal of an environmental challenge.
    • Stress can arise from catastrophic events, major life changes, and daily hassles.
    • Stress Appraisal Theory: Evaluates how individuals perceive and assess stressful events.

    Perceived Stress and Resilience

    • High perceived stress occurs when demands exceed coping abilities.
    • Resilience in trauma leads to effective coping strategies and less mental health impact.

    General Adaptation Syndrome by Hans Selye

    • Stages: Alarm (fight or flight), Resistance (heightened defense systems), Exhaustion (body's inability to adapt).
    • Chronic stress can be just as harmful as the stressor itself.

    Physiological Response Systems

    • SAM Axis: Immediate stress response, releasing epinephrine for fight or flight; characterized by increased heart rate and blood pressure.
    • HPA Axis: Prolonged response responsible for cortisol release, affecting metabolism and immune function.

    Chronic Stress Effects

    • Evolutionary stress responses suited for short-term threats are maladaptive for modern stress.
    • Chronic stress leads to physical damage and heightened health risks.

    Gene × Environment Interactions

    • Diathesis-Stress Model: Genetic predisposition combines with environmental stress to influence health.
    • Differential Sensitivities Hypothesis: Some individuals are more sensitive to environmental effects due to genetic factors.

    Epigenetics and Stress

    • Life events can alter gene expression (gene methylation).
    • Early environment, such as caregiving, significantly impacts stress response more than genetics alone.

    Conclusion on Stress and Health

    • Understanding interactions between genetic predispositions and environmental factors is key to addressing health issues related to stress.
