What is Public Health?Public Health is about what makes us sick, what keeps us
healthy, and what we can do TOGETHER about it.
(Richard Riegelman)
Environmental Health- the sector of public health that
focuses on the prevention and control of disease, injury,
and disability related to the intersections between people
and their environment.
Environmental Health in Public
Health
● Monitoring
● Inform, educate,
and empower
● Research
● Enforce
EOH and CVD: Risk Factors
Risk Factorso Particulate matters
o Water quality
o Diet
o Smoking
o Occupational risks
o Toxins
Particulate matter● Extremely small particles (<10 micrometers in
diameter)
● Sources
o construction sites
o unpaved roads
o fields
o smokestacks
o fires
o industry
o automobiles
o power plants
● CVD risk
● Regulatory standards
Water Quality ● Minor risk factor for heart
disease○ “Hard” water contains higher levels of
calcium and magnesium. Both
naturally preserve heart health.
○ The average American does not
consume adequate amounts of
magnesium.
○ Magnesium disparity found in racial
and ethnic minorities and populations
with lower SES.
Diet- Major risk factor for
cardiovascular disease
- Saturated and trans fats
- Sodium
- Cholesterol
- Sugars
- Environmental factors
- Geographic location
- Socioeconomic status
- Cultural and social factors
Smoking
● The effect of smoking on CVDo lipids, angina, MI, HTN, arrhythmias
● The effect of secondhand smoke on CVDo atherosclerosis (CAD), ↑ blood viscosity,
vascular disease
● Safe levels of secondhand smoke?
● Other complicationso lung cancer, SIDS, stroke
Occupation Related Risks for CVD● Second hand smoke
● Work-related stress
● Insomnia/lack of sleep
● Shift Work
● Fatigue (burnout)
● Sedentary jobs
● Noise
● Heavy lifting
● Lack of time off for physical activity
● Carbon monoxide and carbon disulfide exposure - associated with
heart disease mortality.
● Nitroglycerin exposure
Toxins ● Nitroglycerine
o Death occurred after withdrawal from
exposure
o Varied by age groups
● Cocaineo Irreversible structural damage to the
heart
o Sudden cardiac death
o Accelerate CVD
Conclusion
● Many risks factors for CVD can be attributed to
Environmental and Occupational Health
● Each risk factors has its own pathway that
contribute to CVD
● Need to target each risk factors separately by
specific intervention methods.
● EPA, OSHA, and NIOHSH need to emphasize more
on risk factors that induce CVD
