Public health is about health promotion and disease and injury prevention through research, community intervention and education. It also is about eradicating health disparities.
Public health is a diverse and ever-expanding field. Among other things, it involves disseminating reliable information for policy decisions; identifying systemic inequalities and problems; protecting our health and safety through education and research; and fostering partnerships with individuals, communities and organizations to promote good health.
The elimination of smallpox, stricter automobile and workplace safety standards, increased awareness about the dangers of smoking and information on the nutritional value of foods are all attributable to work done in the field of public health. According to the Centers for Disease Control and Prevention, advances in public health are responsible for lengthening the life expectancy of Americans by 25 years in the 20th century.
Practitioners of public health carry out their mission through organized efforts that draw upon knowledge from many disciplines to address the physical, mental and environmental health concerns of communities and populations. These disciplines include health policy and management, epidemiology, oral health, family health, behavioral science and health education, health communications, occupational safety, environmental health, public health preparedness and international and global health. Public health practitioners conduct research, teach in schools and colleges, help formulate government policy and work in a number of capacities out in the field.
Areas addressed by public health research and community-based programs at the UA Zuckerman College of Public Health include cancer, diabetes, heart disease, nutrition, exercise, violence prevention, environmental hazards, media literacy, bioterrorism and public health preparedness.
No matter what form public health assumes, its goal is always the same: to improve peoples quality of life by focusing on health promotion and disease and injury prevention.
