Determinants of Health

Individual Behavior

Individual behavior is a key determinant of health, influencing both the risk of disease and the ability to maintain good health. These behaviors are often modifiable, meaning they can be changed to improve health outcomes.

Modifiable Determinant: A factor that an individual can change to influence their health.
Most chronic diseases are caused by modifiable determinants.

Modifiable Determinants of Health

Lack of Physical Activity: Increases risk for chronic diseases such as heart disease, diabetes, and certain cancers. Example: Over 250,000 deaths annually in the US are attributed to physical inactivity.
Poor Diet/Nutrition: Consuming high-calorie, low-nutrient foods and sugary drinks increases risk for obesity and related diseases.
Excessive Alcohol Use: Linked to liver disease, certain cancers, and accidents. Example: Over 88,000 deaths annually in the US are due to excessive alcohol use.
Tobacco Smoking: Major cause of preventable diseases such as lung cancer and heart disease. Example: Smoking causes over 480,000 deaths annually in the US.

Example: A student who chooses to exercise regularly and eat a balanced diet is reducing their risk of chronic disease.

Additional info: Modifiable determinants are the primary targets for health promotion and disease prevention programs.

Biology and Genetics

Biological and genetic factors are typically nonmodifiable determinants of health. These are characteristics that individuals are born with or inherit, and they can influence susceptibility to certain diseases.

Nonmodifiable Determinant: Traits or inherited characteristics that cannot be changed.
Examples include age, sex at birth, race/ethnicity, and family health history.

Nonmodifiable Determinants of Health

Age: Older adults are at higher risk for chronic diseases.
Sex at Birth: Biological differences can affect disease risk (e.g., men have higher risk for heart disease before age 60).
Race/Ethnicity: Certain populations may have higher risk for specific diseases due to genetic or social factors.
Health History: Family history of diseases like diabetes or cancer increases individual risk.

Example: A person with a family history of hypertension may be at increased risk, regardless of their lifestyle choices.

Additional info: While nonmodifiable determinants cannot be changed, awareness can guide preventive actions and screening.

Social Determinants of Health

Social determinants are nonmedical factors that influence health outcomes. These include the conditions in which people are born, grow, live, work, and age.

Social determinants are often more important than individual behavior or biological factors in determining health outcomes.

Social Determinants of Health

Determinant	Description	Example
Economic Stability	Ability to afford basic needs and health care	People with a steady income are less likely to experience poor health
Education	Level of education impacts health knowledge and opportunities	Higher education is linked to better health outcomes
Built Environment	Physical surroundings such as housing, parks, and transportation	Safe neighborhoods and access to parks promote physical activity
Community	Social support and community engagement	Strong social networks improve mental health and well-being

Example: A person living in a safe neighborhood with access to healthy foods and good schools is more likely to experience better health.

Additional info: Addressing social determinants is essential for reducing health disparities.

Health Services

Access to quality health services is crucial for maintaining and improving health. Essential services include preventive care, vaccinations, and screenings.

Barriers to health care can be due to lack of insurance or delayed care.

Key Health Services

Doctor check-ups
Vaccinations
Screenings

Example: Individuals without health insurance are less likely to receive preventive services, increasing their risk for disease.

Policymaking

Government policies can have a significant impact on public health by creating safer environments and promoting healthy behaviors.

Examples include laws requiring seatbelt use, bans on smoking in public places, and policies ensuring access to health care.

Examples of Health Policies

Seatbelt laws to reduce injuries in car accidents
Smoking bans in public places to reduce exposure to secondhand smoke
Access to health care through insurance programs

Example: The Affordable Care Act (ACA) increased access to health insurance for millions of Americans.

Additional info: Effective policies can address both individual and population-level health risks.

Summary Table: Types of Determinants of Health

Type	Examples	Modifiable?
Individual Behavior	Physical activity, diet, smoking, alcohol use	Yes
Biology/Genetics	Age, sex at birth, family history	No
Social Factors	Income, education, neighborhood	Partially
Health Services	Access to care, preventive services	Partially
Policy	Laws, regulations, public health programs	Yes (at population level)
