6US Elder trends
- US elder population is increasing
- US population has aged due to increased life expectancy and reduced fertility rate
- For the first time in US history, older adults are projected to outnumber children by 2034
7Successful Aging
- Signs of no significant health problems are an indicator of successful aging
- Often due to social support, diet, exercise, higher SES, low stress, low drug/ alcohol use
8Age effects
-Wrinkles
- Looser skin
- hair thinning and color change
- mobility
- hearing loss, eyesight loss
9Period effects
-Medical technologies
- Health information
- Pandemics (COVID-19)
10Cohort effects
Cumulative person- years
11Aging affects government programs as increasing proportions of elderly will strain...
- Medicare: major health insurance program for the elderly
- Social security: Major national program that provides economic benefits to most elderly
- Worker-to- beneficiary ratio declining (to 2.0 in 2035)
- COVID contributing to fewer births, increased deaths, and fewer immigrants
12Life Course Theory: Cumulative advantage/ disadvantage
- SES disparities in childhood accumulate to affect old age
- Also affects gender/ race/ ethnicity
- Obesity among lower SES women, esp. black women
13Life course theory: Cumulative inequality
- Early disadvantage related to later life health (exposure to health risks, fewer resources to maintain health, less healthy behaviors)
- Midlife resources can mitigate the effects
- Childhood adversity can accelerate biological aging and increase the likelihood of early childbearing/ nonmarital child birth
14Life course theory
maintains that socioeconomic disadvantages originating in childhood accumulative over the life cycle to disadvantage health in old age
15Compared to the past, aim for individuals to be
Healthier, more educated, in better shape, contract diseases in later years, live longer without chronic conditions, enjoy better recovery, COVID may jeopardize gains
16Compared to whites, blacks have
- Higher infant mortality
- Lower life expectancy
- Earlier onset, greater disparity, faster progression of many diseases
- Greater comorbidity
- More disability
17US Infant mortality rates by race and ethnicity
- Lowest among Asians, due partly to SES
- Similar for Hispanics and NH whites
- Highest among blacks
18US life expectancy by race and ethnicity
- Asians have the highest life expectancy by far
- Hispanics and NH whites have similar life expectancy
- NH blacks have lower life expectancy
- American Indians have some of the lowest life expectancies
19Reasons for high African American Mortality
- Socioeconomic factors: poverty, marginal employment, low education levels
- Psychosocial: stress
- Health behaviors: physical inactivity, poor diets, obesity
- Limited access to healthcare: fewer tests for heart disease, cancer, diabetes
- Environmental factors: disadvantaged neighborhoods
20Poverty Rates
- Highest among blacks at 19.5%
- High among Hispanics
- Increased among all race and ethnic groups shown from 2019-2020
21Average life expectancy at birth
77 years
22Discrimination is one of the root causes of accelerated aging because
It contributes to...
- Inflammation
- Early mortality
- Type 2 diabetes
- Metabolic syndrome
- CVD risk factors
- Cognitive decline
- Telomere attrition higher oxidative stress
23Racism
- Institutional racism: housing, employment opportunities, neighborhood/ education quality
- Cultural racism: negative stereotypes, discrimination
- Racism health effects: lower self-esteem/well-being, more distress, early onset of disease, greater disease severity and progression
24Hispanic paradox
Hispanics, compared to non-Hispanic whites, have lower mortality even with lower SES (and lack of health insurance)
25Hispanic paradox is due to
- Migration effects (healthy immigrant effect, return migrant effect)
- Strong social support
- Beneficial cultural practices
- Healthy behaviors
- Data artifact (underreporting Hispanic at death, age misreporting)
26Healthy immigrant effect
suggests that immigrants have a health advantage over the domestic-born US citizens which vanishes with increased length of residency
