Why is America aging?
• Declining birth rates = fewer kids
• Declining mortality rates = more elderly

Demography is not destiny
• Proportion of the elderly population does not necessarily determine health care spending
• Higher rates of illness & disability, but…
• Continued health improvements can counter increased needs caused by growing population
• Public health approaches are the most promising to improve health outcomes of the elderly
![Page 26: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/26.jpg)
3. Nation’s health promotion goals
#1-Attain high-quality, longer lives free of preventable disease, disability, injury, and premature death
• Focus on the quality of the years, not just their quantity

Beyond disease: Geriatric health
• Chronic conditions: Falls, Disability, Urinary incontinence, Oral Health
• Environment: Food insecurity, Social support, Polypharmacy, Healthy communities

Geriatric Issues - Summary
• Several challenges to healthy aging are common among the oldest and poorest elders
• Healthy aging is more than avoiding disease
![Page 31: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/31.jpg)
4. Public health approach
• Definition of Public Health = Assuring the conditions under which people can be healthy (Institute of Medicine, Committee for the Study of the Future of Public Health. The
future of public health. Washington, DC: National Academy Press, 1988)
• Population / community / system focus
• Interest in prevention vs. cure
• Emphasis on health vs. disease
![Page 32: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/32.jpg)
Types of prevention
• Primary – prevent problem from happening, e.g. immunizations
![Page 33: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/33.jpg)
Types of prevention
• Primary
• Secondary – detect problem early and treat before serious harm results, e.g. blood pressure or breast cancer screening
![Page 34: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/34.jpg)
Types of prevention
• Primary
• Secondary
• Tertiary – after a health problem has happened, maximize independence & quality of life, e.g. rehab, in-home supportive services
![Page 35: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/35.jpg)
Falls - a public health approach
• Primary – Promote physical activity, reduce polypharmacy, universal housing design (for all older adults)
• Secondary - Strength training, environmental modifications (for at-risk older adults)
• Tertiary – Counseling to decrease fear of falling, improve primary care ID/treatment of falls, social support interventions
![Page 36: The Implications of an Aging Population Steven P. Wallace, Ph.D. Professor, UCLA School of Public Health Assoc. Dir., UCLA Center for Health Policy Research](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d805503460f94a649d0/html5/thumbnails/36.jpg)
Poverty – a cross cutting risk
• Primary – Assure a living wage with adequate health care and pension
• Secondary – Maintain the communal risk feature & disability benefits of Social Security
• Tertiary – Provide public assistance (SSI) at the Elder Economic Security Standard level

The Problem: Federal Poverty Guideline
The current measure needs to be revised: it no longer provides an accurate picture of the differences in the extent of economic poverty among population groups or geo-graphic areas of the country, nor an accurate picture of trends over time. The current measure has remained virtually unchanged over the past 30 years. Yet during that time, there have been marked changes in the nation’s economy and society .... (National Research Council, 1995, page 1)

Elder Economic Security Standard (EESS)
• Adjusted for local (county) costs of living versus national average
• Takes actual costs of basic necessities for older households
• Includes housing, food, transportation, health care, and other costs

Conclusions
1. The U.S is becoming older as a nation2. Demography is not destiny with
improving health and changing medical practice
3. Healthy aging goes beyond adding years to life and focuses on adding life to years – involves increased attention to chronic and nonfatal conditions
4. Public health approaches to prevention using multilevel interventions are possible to reduce challenges to healthy aging… including using a more realistic assessment of “poverty”
