public health definition
complete physical, mental, and social-well being
public health focus
"art and science" of preventing disease, prolonging life, and promoting health
3 core functions of public health?
1. assessment: community health surveys (monitor disease rates)
2. policy development: vaccination mandates, nutrition guidelines
3. assurance: availability of necessary health services
primary prevention
, prevention before disease occurs (immunizations, education)
secondary prevention
early detection of disease for intervention (screenings, BP checks)
tertiary prevention
reduce complications, chronic disease management (rehab, physical therapy)
what is public health?
prevention-oriented, protecting health of overall populations
what is community health?
care is directed to individuals, families, groups; individual-focused (acute/chronic care)
upstream interventions
addresses root causes (policies, housing, environment); population-level prevention
downstream interventions
individual behavior change (treatment/diagnosis, education); individual treatment
upstream interventions for obese client
health policy changes, school program lunch modifications
downstream interventions for obese client
individual strategies to reduce weight, personal lifestyle changes
microscopic theories
apply to individual behavior
macroscopic theories
apply to populations
what are microscopic theories
Orem's theory, Health Belief Model, Pender's Health Promotion model, transtheoretical
macroscopic theory
Milio's Framework for Prevention
Orem's Theory
