Health and Health Promotion

HEALTH
A. Definitions of health vary
  • Traditional definition: freedom from disease 
  • 1958 World Health Organization definition: “state of complete physical, mental and social well-being and not merely the absence of disease and infirmity” 
B. Health belief model
  • Psychological and behavioural theory 
  • Attempts to explain individual health behaviours 
  • Health behaviours

    1. The individuals perception of susceptibility of illness 
    2. The individuals perception of seriousness of the illness 
    3. The likelihood that the person will take preventive action 

  • Modifying Factors
    1. Cultural beliefs 
    2. Economics 
    3. Political factors 
    4. Social factors 
    5. Personal beliefs 
Health Promotion
A. Definitions
  1. Health Promotion Behaviour is a behaviour in which the client views health as a goal and engages in behaviours designed to achieve or maintain that goal 
  2. Health Care includes prevention, early detection, treatment and rehabilitation for clients with potential for or existing illness or disability 
  3. Healthy Lifestyle can increase or maintain client’s level of wellness and functional ability 
  4. Health Screening (for risk factors or illness) can prevent or minimize illness and disability 
  5. Disease Prevention Behaviors are behaviours designed to decrease the likelihood/risk of illness 
    • Primary prevention 

      1. Health promotion and disease prevention 
      2. Applied to clients considered physically and emotionally healthy
      3. Example: exercise programs, healthy diet 
    • Secondary prevention 

      1. Early detection of illness 
      2. Focuses on individuals who are experiencing health problems and illness and who are at risk for problems and illnesses and who are at risk for complications 
      3. Activities are directed at diagnosis and prompt treatment 
      4. Example: breast self examination, cholesterol screening 
    • Tertiary prevention 

      1. Prevention of further deterioration in disease or disability 
      2. Occurs when a defect or disability is permanent and irreversible
      3. Activities are directed at rehabilitation 
      4. Example: alcoholics anonymous 
B. Primary Health Care
  • Accessible, community-based or work-based health care services based on principle of universal access, which ensures health care for all individuals regardless of employment or insurance status

      • Health promotion depends on seven factors of cognition-perception
          1. Importance of health to the person 
          2. Perceived control of health 
          3. Perceived self-efficacy 
          4. Definition of health 
          5. Perceived health status 
          6. Perceived health benefits from the health-promoting behaviour 
          7. Perceived barriers to the health-promoting behaviour 
        D. Risk Factors – probability of acquiring a particular health problem
        • Varies with age, race, ethnicity, gender

            • Recommendations vary but generally accepted to perform screening at onset of adolescence
            • Significantly more prevalent in girls than boys
            • Early intervention important because untreated scoliosis can lead to disfigurement, impaired mobility, and cardiopulmonary complications
            • Technique - clothing should be removed from upper body
              1. While standing, check adolescent for asymmetry of shoulders, scapula, hips or waist
              2. Assess for misalignment of spinous processes - lateral curvature and convexity of thoracic spine indicate scoliosis
              3. With feet together and legs straight, have adolescent bend forward until back is parallel to floor; check for prominence of ribs on one side only and hip and leg asymmmetry - chest wall on side of convexity is prominent and scapula on side of convexity is elevated
            • Abnormalities are to be followed up by a health care provider and referral to orthopedist may be necessary for severe curvatures
            V. Testicular Self-Examinations
            • Monthly self-examination should begin in adolescence, since this is the highest risk group
            • Best time to perform exam is during or after a bath or shower when the scrotum is relaxed
            • Limited research to determine if regular examinations reduce death rate but they are strongly encouraged for men with risk factors such as
              1. family history of testicular cancer
              2. cryptochidism
              3. previous germ cell tumor in one testicle
            • Findings that should be reported to a health care provider include
              1. hard lumps or nodules
              2. change in size, shape or consistency of the testes

            F. Compliance
            • Definition: adherence to primary or secondary prevention recommendations
            • Factors influencing compliance
                1.  Personal meaning and perceptions: knowledge, values, beliefs, outcome expectations
                2. Social factors: environmental context, social relationships, social support, societal norms, economic resources
                3. Deficiencies in the health care system: access, costs, wait time, monolingual services
               G. Noncompliance
              •  An individual’s informed decision not to adhere to a therapeutic recommendation
              • Individual unable or unwilling to alter habitual behaviours or adopt new behaviours necessary to a prescribed therapeutic regimen 
                TIMING OF MAMMOGRAMS 
                • The National Cancer Institute (NCI) and the American Cancer Society differ in their recommendations for scheduling of mammograms 
                • NCI recommends (2002): 
                1. Women in their 40s should be screened every one (1) to two (2) years with mammography 
                2. Women aged 50 and older should be screened every one (1) to two (2) years 
                3. Women who are at higher than average risk of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and the frequency of screening 
                • The ACS guidelines for the detection of breast cancer in asymptomatic women (2002): 
                1. Women 40 years of age and older should have a mammogram every year 
                2. Women 40 years and older should have a physical examination of the breast every year, performed by a health care professional, such as a physician, physician assistant, nurse or nurse practitioner. This examination should take place near and preferable before, the annual mammogram 
                3. Women 20-39 should have a physical examination of the breast every three (3) years, performed by a health care professional such as physician, physician assistant, nurse or nurse practitioner 
                • BSE is an option for women starting in their 20s. Women should be told about the benefits and limitations of BSE. Women should report any breast changes to their health professional right away 


                POINTS TO REMEMBER:
                • Measure vital signs when the client is at rest
                • Compare both sides of the body for symmetry
                • Assess the systems related to the client's major complaint first
                • Offer rest periods if client becomes tired
                • Culture and religious beliefs may play a role in observed differences
                • Warm hands and equipment such as stethoscope before touching client 
                • Tell client what you are going to do before touching client
                • Normal variations exist among clients and there is a range of normalcy for all physical findings
                • Maintain the client's privacy throughout the examination
                • Control for environmental factors which may distort findings
                • Check equipment prior to exam for functioning
                • Consider growth and developmental needs when assessing specific age groups
                • Integrate client teaching throughout the exam

                5. If you are finding for psychoanalytic theory and method of therapy than let’s have a look at Transactional analysis? It is analysis is a psychoanalytic theory and method of therapy wherein social transactions are analyzed to determine the ego state of the patient as a basis for understanding behavior. In it, the patient is taught to alter the ego state as a way to solve emotional problems. The benefits of analysis can increase self-awareness, also promote personal reflection.
