Gerontology and Gerontological Nursing: Key Concepts and Demographics

Gerontology

• Definition: Gerontology is the study of aging processes of individuals across the life course (Gerontological Society of America, 2024).

• Etymology: from Greek gérōn meaning "old man" and logía meaning "study of".

• Origin of the term: Coined by Élie Metchnikoff in 1903; Metchnikoff was a Nobel Prize-winning aging researcher.

• Notable pioneers:

  • James E. Birren (Professor Emeritus, 1918–2016): American gerontologist, founder of organized gerontology, president of The Gerontological Society of America, author of over 250 publications.

Scope and purpose of Gerontology (as a field)

• Takes a holistic approach to improving the standard of living for elderly members of the community.

• Studies the medical care and needs of the elderly with emphasis on physiological aging, including diagnosis, treatment, prevention of diseases, and rehabilitation in the elderly. (Concordia University Chicago, 2024)

• Historical note: GERIATRICS emerged in the 1970s with a broader focus on holistic health and wellness of the aging population (Jones, 2021).

Geriatric Nursing

• Definition: An evidence-based nursing specialty addressing the unique physiological, social, psychological, developmental, economic, cultural, spiritual, and advocacy needs of older adults (Vetter, 2022).

• Practice setting: Gerontological nurses work in various healthcare settings, collaborate with interdisciplinary teams, and advocate for the overall health and well-being of the elderly.

Development of Gerontological Nursing

• 1950: 1st gerontological nursing text published; geriatrics recognized as a nursing specialty.

• 1961: ANA recommends a specialty group for geriatric nurses.

• 1966: Formation of the geriatric nursing division of ANA.

• 1969: Development of standards for geriatric nursing practice.

• 1970s–1980s: Key organizational growth in the field (timeline continues below).

• 1976: ANA changes name from Geriatric Nursing Division to Gerontological Nursing Division.

• 1981: First international conference on Gerontological Nursing.

• 1982: Development of the Robert Wood Johnson Teaching Home Nursing Program.

• 1984: Formation of the National Gerontological Nursing Association.

A Perspective on Aging

• Aging as a developmental process: aging is gradual, continuous, and involves physical, psychological, and social changes over time.

• Developmental processes reflect how an organism grows and matures over its lifespan.

Aging: Types of Aging

• CHRONOLOGICAL AGE: Measured by the number of years lived.

  • Young Old: $65-74$

  • Middle Old: $75-84$

  • Old-Old: $85-100$

  • Elite Old: Over $100$

• BIOLOGICAL AGE: Physical changes that occur as people age; cells gradually lose repair and regenerative capacity.

• PSYCHO-SOCIAL AGE: Expressed through ability, learning capacity, skills, memory, emotions, and judgment; based on behavior and feelings.

Factors of Aging

1. Biological factors

2. Cellular senescence: decline in the ability of cells to divide and replicate (Campisi, 2013).

3. Telomeres shortening: Each time a cell divides, telomeres shorten; when too short, the cell can no longer divide, leading to aging (Blackburn, Epel, & Lin, 2015).

4. Genetic factors: Genetic predispositions influence rate and manifestations of aging.

5. Oxidative stress and damage: Cells accumulate damage from oxidative stress from metabolic processes.

6. Hormonal changes: Shifts in hormonal levels such as decreased growth hormone, estrogen, and testosterone impact metabolism and health (Thompson & Buford, 2022).

7. Decline in organ and system function: Reduced efficiency and resilience with age, increasing susceptibility to disease.

Menopause & Andropause

• Symptoms and timeline:

  • Menopause: hot flashes, mood swings, forgetfulness, sleep disturbances, decreased motivation, lack of focus, low energy, muscle loss, nausea.

  • Andropause: erectile dysfunction, bone loss, joint pain.

• Age ranges:

  • Menopause: typically ages $45-55$.

  • Andropause: typically ages $40-60$.

• Sources cited: NHS (2024); balancedmedicalsolutions.com

• Implications: Hormonal shifts affect metabolism, energy levels, mood, and risk for certain diseases; management includes lifestyle interventions and medical treatment as appropriate.

Psychological Factors

A. Cognitive decline: Some cognitive abilities decline with age; others (e.g., vocabulary, accumulated knowledge) remain stable or improve.
B. Emotional regulation: Older adults may exhibit better emotional regulation and stability than younger adults.
C. Changes in personality: Traits tend to stabilize with age; individuals often become more agreeable and less neurotic.

Social Factors

A. Role transition: Retirement, becoming grandparents, caregiving for elderly parents.
B. Social network: Potential losses of peers and family; maintaining social connections is crucial.
C. Community engagement: Participation in community activities provides sense of purpose and social integration.

Environmental & Lifestyle Factors

A. Health behaviors: Diet, exercise, sleep, stress management influence aging and health outcomes.
B. Environmental exposures: Pollutants/toxins affect aging rate and disease susceptibility.
C. Access to healthcare: Quality healthcare and preventive measures mitigate aging effects and improve quality of life.
D. Cultural perspectives: Cultural beliefs and practices shape experiences and perceptions of aging.

Ageism

• True or False? There are three major misconceptions about aging:

  • Disease in old age is normal.

  • Older adults have no future, so health promotion is wasted.

  • Damage to health from poor diet and inactivity is irreversible.

• Summary: Ageism is a negative attitude toward aging and older adults and can affect care and policy.

Roles of the Gerontological Nurse

• CARE PROVIDER: Provide direct and hands-on care and nursing interventions.

• TEACHER: Organize and provide instructions on healthy aging.

• ADVOCATE: Act on behalf of older adults to promote their best interests.

• RESEARCHER: Read and implement results of reliable and valid studies.

• MANAGER: Plan and coordinate the care of the elder.

Healthcare Settings for Geriatric Care

• ACUTE CARE SETTINGS – Hospital-based.

• IMMEDIATE/INTERMEDIATE CARE FACILITY – Less intensive.

• ASSISTED LIVING – Community setting.

• LONG TERM CARE FACILITY.

• HOME HEALTH CARE – Nurses from agencies/hospitals.

• HOSPICE CARE – For dying persons.

• REHABILITATION CENTER – Therapy sessions.

• CARE RETIREMENT COMMUNITY – Campus/subdivision-like setting.

Demography of Aging and Implications for Health & Nursing Care

• GLOBAL AGING: Demography involves age distribution, trends, and characteristics of older people in the global population.

• KEY DEMOGRAPHIC TRENDS:

  • Increased life expectancy: from $64$ years in 1990 to $72$ years in 2016 (WHO)$.$

  • Declining fertility rates: fertility rates have declined below 2.1 children per woman.

• Growing elderly population: By $2050$, the number of people aged 60+ will double to about $2.1 ext{ billion}$ globally, with particular growth in developing regions (UN, 2021).

• Global aging in years:

  • 2017: global population aged 60+ reached more than $962 ext{ M}$; more than twice the number in 1980 (≈$382 ext{ M}$).

  • 2030: older people expected to outnumber children under age 10–14 (1 B vs 1.35 B).

  • 2050: projected to reach $2.1 ext{ B}$.

• Global aging data by year (illustrative):

  • 2015: ~$901 ext{ m}$(~16.5% of world population).

  • 2030: ~$1,402 ext{ m}$ (~12.3%).

  • 2050: ~$2,092 ext{ m}$ (~21.5%).

• Regional/global differences:

  • Nations with high elderly shares: Monaco, Japan, Italy, Greece, Finland, Germany, Slovenia, Croatia, Romania, etc.

  • North America and Europe show high aging; Africa is younger but North Africa shows aging trends; Asia has significant aging in countries like Japan and China; Brazil and other regions are experiencing aging.

Aging in the Philippines: Demography and Implications

• Demographic trends in the Philippines:

  • Increased life expectancy: male from $57$ to $71$ years; female from $63$ to $77$ years.

  • Declining fertility rate: about $2.5$ children per woman (down from >6 in the 1960s).

• Vital statistics (illustrative): Fertility, life expectancy, and under-60 mortality have shown changes over periods; data show shifts toward an aging population.

• Growing elderly population in regions: National Capital Region (NCR), Central Luzon, and CALABARZON have the largest shares of senior citizens (almost 4 in every 10 in 2020).

• UNFPA projection: Filipinos aged 60+ projected to reach about $15.3 ext{ million}$ by $2050$ (≈ 15.9% of total population).

• Implications for health and nursing care in the Philippines: increased chronic diseases, mental health concerns, higher demand on health care infrastructure, workforce challenges, need for preventive care, technological solutions (telemedicine, wearables), policy and funding, and family caregiver support.

Implications for Health & Nursing Care (General)

• Personalization: Develop a Personalised Care Plan to address health needs, preferences, and lifestyle.

• Independence: Promote independence with home modifications and assistive technologies for self-care.

• Health education and wellness: Provide guidance on nutrition, exercise, mental health to enhance well-being and prevent complications.

• Coordination of care: Nurses to collaborate with other health professionals to manage chronic conditions.

• Planned activities: Tailored activities with time for thinking, reflection; group or pair activities.

• Rewards and appreciation: Use progression tracking, checklists, verbal praise; consider badges or rankings for motivation with baby boomers.

Implications: Population Aging—Key Takeaways for Practice

• Baby Boomers (1946–1964) are a major demographic group entering older adulthood now through 2030s; they bring characteristics such as strong work ethic, self-assuredness, competitiveness, goal orientation, resourcefulness, and preference for independence.

• Healthcare systems must adapt to increased demand for geriatrics expertise, chronic disease management, and preventive care; incorporate technology and telehealth where appropriate; train workforce and support family caregivers.

• Ethical considerations include maintaining autonomy, dignity, and person-centered care while addressing resource constraints and policy changes.
