Public Health Majors Guide

What Does it Mean to Study Public Health Major?

According to the World Health Organization, the definition of health is “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.”

The broad job description of public health professionals is to evaluate and regulate the health needs of the public population, focusing on improving health where they can. Students who pursue a public health major have the opportunity to tackle the often-times complex problems that face health care systems and services, perhaps to improve quality or broaden availability. Public health professionals also work to promote healthy behaviors and habits on an individual, family, professional or community level and even to have an impact on chronic disease.

Types of Public Health Degrees

Public health degree programs focus on both the science and politics of health and are designed to address their interconnections. Degrees are available from the associate to PhD level, varying in intensity and scope.

Some public health degree programs may separate the major into categories such as biostatistics, global health, nutrition, and public health administration. Public health degree programs also could be offered with concentrations or specializations, such as biostatistics, child health, epidemiology, health education, environmental health or international health. Whichever degree you choose, you are sure to be impressed by the range of issues that public health addresses.

Before you decide to pursue a degree in public health, consider the degree levels available:

Associate Degree in Public Health

An associate degree in public health is a solid first step toward building knowledge about the field and eventually working toward a bachelor’s degree in this field. You may also be able to gain entry-level work in a public health setting with this degree type, although potential positions you’ll qualify for may be limited.

Factors prospective students should consider

Typically, students need to have a high school diploma or GED to be admitted into an associate degree program in public health. At the associate degree level, programs can be found online or campus-based and may be called ‘public health’ or a similar name. Programs in health administration could provide a similar stepping stone toward advancement to a public health bachelor’s degree.

Type of courses and clinical experiences offered

Students complete both general education requirements in the arts and humanities, math, history and more as well as requirements in their major. Classes in the major could include moral issues in healthcare, public health in America, and foundations in nutrition. A course in science, like chemistry with a lab, could also be required.

Skills students can learn

Is public health a good major? Students in an associate level program can build foundational knowledge, including the importance of public health and the health of a community, along with an understanding of the political and social factors that impact public health policy. Students may also learn why public health is so dynamic, political and controversial — and how they can shape the health of their own communities and those of others. They can also improve their skills in critical thinking and interpersonal communication.
