global aging
% less than 60 years old = 10% in 2000 and 21+% in 2015 effect of aging: - health care use 3 to 5x greater - 50% have two or more chronic condition
intimate partner violence
- 1 in 5 women and girls aged 15-49 reported experiencing physical and/or sexual violence by an intimate parter within a 12 month period
ACA works:
- 11.4 million enrolled in Exchanges as of March 2019 (85% with subsidies, 50% with cost-sharing reductions) - 17.0 million newly enrolled in Medicaid as of 2017 (Q3) (12.4 million through expansion, 4.6 million previously eligible) - 19.1 million total newly insured compared to 2010 (7.4 percentage point reduction (17.8% to 10.4%) among those under age 65, 46.5 million uninsured non-seniors in 2010 compared to 27.4 million in 2017, largest reduction in the number and percentage of uninsured since the implementation of Medicare and Medicaid in 1966)

prevalence rates of intimate partner violence by WHO region
- 37.7% = South East Asia - 37.0% = Eastern Mediterranean region 36.6% = Africa
if the world were 100 people:
- 51 urban, 49 rural - 78 electricity, 22 no electricity - 87 safe drinking water, 13 unsafe drinking water - 15 would be undernourished - 48 would live on less than $2 USD a day - 1 out of 2 children will live in poverty
WHO Global Health Observatory (GHO) data
- 71% of the world's population used safely managed drinking water services in 2015 - 2.3 billion people still lacked basic sanitation services in 2015 - 15% of people in sub-Saharan Africa had basic hand washing facilities with soap and water at home in 2015 - 5.4 million children under age 5 died in 2017 - 1 million children under 5 died due to prematurity in 2016
half of the population growth will take place in 9 countries (2017 to 2050)

1960s: social insurance for the aged
- PL 89-97 signed into law on July 30, 1965 and was effective July 1st as Title 18 of the Social Security Act (culmination of 8 years of effort)
rural vs. urban
- Poorer health - Less access to health care - Poorer quality of health care - Higher proportion of elderly, due to industrialization and migration of young workers to urban areas - Slower epidemic potential (population density), but lower rates of immunity - Higher cost of providing services; e.g., water, electricity, waste disposal
conclusions from demographic studies
- The majority of the world's population lives in developing countries - Although fertility is declining, increases in population will occur primarily in developing countries in coming decades - Developed countries must cope with a shrinking productive age population and a burgeoning elderly population - The majority of the global population live in urban areas - The world's wealth is concentrated in a minority of countries - Poor sanitation and hunger are concentrated primarily in countries in sub-Saharan Africa and South Asia - Population density (which promotes emerging diseases) is greatest in developing countries, particularly China, India, and Bangladesh - Global inequity remains a major problem
health care spending as a percentage of GDP, 1980-2014
- U.S. highest (16.6%), will approach 20% in the next few years - U.S. grew at a much faster rate - 1 out of 5 dollars is spent on the health care system - spending is almost 2x as much as other countries but quality of health care is not necessarily 2x as good
why does the U.S. spend so much more on health care?
- U.S. pays more for most health care personnel: higher prices - U.S. also provides more services within each of the units of service measured in the Anderson et. al study - more intensive hospital days: more tests which are more frequent and expensive - more intensive office visits
health care spending per capita by source of funding
- U.S. spends most on private spending compared to other countries
conclusions
- aging is complex - reject age stereotypes - they're bad for your and others' health - growing ethnic diversity - wide variety of ways for public health to promote healthy aging - it's a lifelong process - early and midlife influences are influential, but never too late to intervene - not just about preventing disease, instead promoting health - must pay attention to aging population for public health - growing proportion of the population - ignoring has consequences: rising rates of STIs, potential health care burden - public health key role in intervention and improving health span (physical activity interventions effective and may reduce caregiver burdens)
complexities of aging
- biological, psychological, and social changes at varying rates - linear vs. stage based changes - not just genes, environment matters a lot - age is positively associated with heterogeneity in a population (substantial individual differences in rates of change and diversity among older adults)
strategies to prevent the spread of the flu
- cover mouth and nose when sneezing - wash hands frequently with soap and water or alcohol - avoid touching eyes, nose, and mouth - avoid contact with sick people - avoid crowded congested environments - if sick, stay home and don't expose others - follow public health advice - get flu shots - take antiviral drugs if physician recommends
H5N1 intervention strategies
- culling (killing of infected flocks) - innovative surveillance strategies: identification and analysis of human to human clusters, characterization of strains, and necessity for vaccine development - vaccination of bird handlers (vaccine being developed) - vaccination of commercial bird flocks
poor versus rich countries
- deaths of children under 5 years of age = 20:1 - malnutrition = 10:1 - life expectancy = -16 years - internal country disparities
positives of aging
- declines in addictive behaviors and crime, reduction in severe psychiatric disorders, and stability in psychological wellbeing - continuing increases in vocabulary - greater selectivity in friendship and increased contact with close family - increases in leisure time and altruistic behaviors
negatives of aging
- decreased reaction time, psychomotor speed, and verbal memory - declines in strength and walking speed - loss of skeletal muscle - greater mortality
aging is a lifelong process
- early and mid life influences: birth weight, education, physical activity and other health behaviors determine the degree to which enter later life with cognitive and physical reserves
value of promoting physical activity in late life
- exercise training (especially aerobic) increases cognitive function (even for people with dementia and related cognitive impairments) - can promote physical function and reduce risk of falling
more negative expectations about aging leads to
- fatalism - less frequent preventative health behaviors
consequences of rapid population growth
- food supply - education system - resources and energy - economy and jobs - natural environment - social structure - political system - international relations
what can we do to reduce ageism in health care?
- formal education (increasing and improving geriatrics training) - informal education (changing exposure) - policies (incentivizing working with older patients, improving reimbursement, age-friendly community initiatives)
most common causes of death for population age 65+
- heart disease - cancer - stroke - lung conditions - Alzheimer's disease - diabetes
most prevalent conditions for population age 65+
- hypertension - arthritis - heart disease - cancer - diabetes - vision limitation
reference pricing
- identify providers with good outcome/quality profile - select providers at or below median or other standard (reference price) - for patients using select providers = full payment for service - for patients not using select providers = payment limited to reference price and patient responsible for balance bill above reference price
employers who offer health insurance in the U.S.
- if work for large firms (200+ workers), almost guaranteed health insurance - small companies less likely to offer health insurance benefits - even smaller companies (fewer than 10 workers) = 50% chance of getting health insurance benefits - way we recruit and retain workers by offering benefits and including health insurance helps to make a better workforce
essential factors for disease eradication
- knowledge of its epidemiology and transmission patterns/mode - availability of effective tools for diagnosis, treatment and prevention - knowledge of local cultural and political characteristics - community acceptance and mobilization - political will and leadership - adequate and sustained funding
ageism in health care
- lack of geriatricians due to low pay - lack of representation in clinical trials - attributing problems to aging instead of disease - risk of both under-treatment and overtreatment - case study: misconceptions about older adults' sexual activity
public insurance in the U.S.
- medicare (1965) - medicaid (1965) - children's health insurance program (CHIP) (1997) - affordable care act (2010)
most debilitating conditions for population age 65+
- mental distress - stroke - vision limitation - hearing limitation - diabetes - lung conditions
america and most of the world is aging
- population aging = shift in the age distribution of the population toward older ages - increases in the percentages of the population reaching old age - change in population's distribution across age groups - changes in ratios of older to young population
aging is complex
- positive and negative changes with aging - lots of diversity in aging and among older adults - negative age stereotypes appear to undermine healthy aging - watch out for harmful age assumptions in health care settings
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
evolution of private health insurance
- prior to 1929, no private or public health insurance (except Workers' Compensation for injured workers) - between 1929 and 1945, most private health insurance was purchased from non-profit Blue Cross (hospital) and Blue Shield (physician) plans, which grew rapidly despite the Great Depression (health insurance also grew rapidly as an employment-based benefit during WWII, because it was exempt from the general wage freeze in effect for the entire economy) - starting in 1946, for-profit commercial insurance companies expanded rapidly into the private health insurance market
demography is not destiny
- proportion of population age 65+ does not necessarily determine health care spending - while elderly do have higher rates of illness and disability, continued health improvements can counter increased needs caused by growing population - public health approaches can improve health outcome of older adults - improve health span (amount of time without disease and disability), not just life span
barriers to H5N1 control
- reservoir in wild birds and ducks - economic impact of culling of poultry stocks - popularity of "wet markets" promotes transmission within poultry and to other species - resistance to antivirals and vaccines - mistrust of rich nations
longitudinal evidence: more positive age-beliefs
- social engagement - likelihood and timing of cardiovascular events - recovery from heart attack - longevity - functional health - memory - hearing
changing focus from disease to health
- supportive care and services are key to maximizing functioning and well-being across the life span - focus on prevention rather than retroactive treatment of disease - promotion of function and well-being (too much/low value health care might harm quality of life and function)
impact of poor water and sanitation
-Causes 88% of diarrhea cases; 1.5 million deaths annually -High infant mortality due to dehydration resulting from diarrhea -No access to improved water - 884 million (13% of the global population)
evolution of US payment methods

major elements of the ACA of 2010
1. to reduce the number of uninsured in 2014: - mandates = to prevent cost-shifting and free riders from opting out of insurance until they need it - subsidies = to make insurance more affordable to low and middle income individuals and families so they can comply with the mandate, plus expansion of medicaid to make health care accessible to those with the lowest incomes - insurance market reforms = to prevent private insurers from avoiding "high risk" members and to encourage competition based on standard insurance policies 2. to protect everyone with insurance: - provide new federal protections to those w/ private insurance - eliminate pre-existing condition exclusions for children (2010) and adults (2014) - protect anyone who loses their employment based-insurance

conclusions of health care financing and expenditures in the U.S.
The U.S.: - is the only advanced economy that tolerates having a significant portion of its citizens uninsured - has the largest private market for health care financing of any nation - spends more per capita on health care services than any other high-income nation, but has some of the poorest health outcomes -supports incremental changes, based on market-oriented solutions, rather than fundamental reform - although public support for Medicare for All indicates that there is broader support for single payer than many analysts thought
health care spending as percentage of GDP
U.S. has the highest (17.1%)
total health expenditure per capita and GDP per capita
