15.1 Historical and contemporary health disparities

Native Americans face significant health disparities compared to the general U.S. population. They have lower life expectancy, higher infant mortality rates, and increased prevalence of chronic diseases like diabetes and heart disease. These issues stem from a complex mix of historical, social, and economic factors.

Access to healthcare is a major challenge for Native communities. The Indian Health Service, while crucial, is chronically underfunded. Many Native Americans lack health insurance and face cultural and geographic barriers to care. These disparities are further compounded by environmental health risks and the lasting impacts of historical trauma.

1 of 3

• Native Americans experience a significant life expectancy gap compared to the general U.S. population
  • On average, Native Americans live 5.5 years less than the overall U.S. population
  • Life expectancy for Native Americans is approximately 73 years, while the national average is 78.5 years
• Infant mortality rates among Native American populations remain disproportionately high
  • Native American infants are 1.6 times more likely to die before their first birthday compared to non-Hispanic white infants
  • Contributing factors include lack of prenatal care, poverty, and limited access to healthcare facilities

Chronic Disease Prevalence

• Diabetes prevalence among Native Americans is significantly higher than the national average
  • Native Americans are 2.3 times more likely to be diagnosed with diabetes compared to non-Hispanic whites
  • Type 2 diabetes affects up to 60% of some tribal communities
  • Factors contributing to high diabetes rates include genetic predisposition, diet changes, and lack of access to healthy foods
• Cardiovascular disease rates are elevated in Native American populations
  • Heart disease is the leading cause of death among Native Americans
  • Native Americans have a 20% higher rate of heart disease compared to non-Hispanic whites
  • Risk factors include high blood pressure, obesity, and smoking

Healthcare Access

Indian Health Service (IHS) and Its Limitations

• Indian Health Service serves as the primary healthcare provider for many Native Americans
  • Established in 1955 to fulfill federal treaty obligations for healthcare
  • Operates hospitals, health centers, and clinics on or near reservations
• IHS faces significant funding and resource constraints
  • Per capita spending for IHS patients is less than half of the national average
  • Chronic underfunding leads to shortages of medical equipment, staff, and services
• Geographic barriers limit access to IHS facilities
  • Many Native Americans live in rural or remote areas far from IHS clinics
  • Limited transportation options further complicate access to care

Barriers to Healthcare Access

• Native Americans experience higher uninsured rates compared to other racial and ethnic groups
  • Approximately 22% of Native Americans lack health insurance, compared to the national average of 8%
• Cultural barriers impact healthcare utilization
  • Language differences between patients and providers
  • Lack of culturally competent care and traditional healing practices integration
• Limited specialty care and mental health services in many Native American communities
  • Shortage of specialists in rural areas where many reservations are located
  • Mental health services are often underfunded and understaffed

Social Determinants of Health

Environmental Health Challenges

• Native American communities face disproportionate exposure to environmental hazards
  • Water contamination from industrial activities (uranium mining on Navajo lands)
  • Air pollution from nearby power plants and factories
• Climate change impacts exacerbate health risks for Native American populations
  • Increasing frequency of extreme weather events affects traditional food sources and water supplies
  • Rising temperatures contribute to heat-related illnesses and respiratory problems

Socioeconomic Factors and Health Disparities

• Poverty rates among Native Americans are significantly higher than the national average
  • 25.4% of Native Americans live below the poverty line, compared to 11.4% of the general population
  • Limited economic opportunities on reservations contribute to persistent poverty
• Educational attainment gaps impact health outcomes
  • Lower high school and college graduation rates among Native Americans
  • Education level correlates with health literacy and access to preventive care
• Food insecurity and nutrition-related health issues
  • Many reservations are located in food deserts with limited access to fresh, healthy foods
  • Reliance on processed foods contributes to obesity and related health problems

Historical Trauma and Mental Health

• Intergenerational trauma from historical injustices affects Native American health
  • Forced relocation, boarding schools, and cultural suppression have long-lasting impacts
  • Higher rates of depression, anxiety, and substance abuse linked to historical trauma
• Suicide rates among Native American youth are alarmingly high
  • Native American youth have suicide rates 2.5 times higher than the national average
  • Lack of mental health resources and cultural support contribute to this crisis
• Substance abuse issues disproportionately affect Native American communities
  • Higher rates of alcohol and drug abuse compared to other racial groups
  • Limited access to culturally appropriate treatment programs hinders recovery efforts
