Preventive Healthcare: Level Of Prevention, Causes & Methods Of Prevention

What Is Preventive Health Care?

Prevention or prophylaxis consists of disease prevention steps. Environmental conditions, genetic predisposition, disease agents, and lifestyle decisions affect diseases and disability and they are complex mechanisms that start before people know that they are affected.

Disease prevention depends on preventive measures that can be listed as:

  • Primal
  • Primary
  • Secondary
  • Tertiary.

Millions of people die every year from preventable deaths. A research study conducted in 2004 found that about half of all deaths in the United States in 2000 were attributed to preventable activities and exposures. Cardiovascular disease, chronic respiratory diseases, involuntary accidents, diabetes, and certain infectious diseases were leading causes.

According to figures by the World Health Organization (WHO), nearly 55 million people died in the world in 2011. Two-thirds of this group died in the events of non-communicable diseases, including cancer, diabetes, and chronic cardiovascular diseases.

This is an improvement from 2000 when these diseases accounted for 60 percent of the deaths. Preventive healthcare is essential considering the global increase in chronic disease prevalence and deaths.

There are several strategies for disease prevention. It is recommended that adults and children visit their doctor on daily checks even when they feel well, to carry out disease testing, recognize the risk factors for illnesses, share tips for healthy and balanced diets, keep up to date with immunizations and stimuli and maintain a good relationship with a healthy lifestyle.

  • Tests for hypertension (high blood pressure)
  • High blood sugar (HBSC),
  • Diabetic hypercholesterolemia (high blood cholesterol)
  • Colon cancer screening

Depressive diseases like chlamydia, Syphilis, Gonorrhea, colorectal mammography (to test for breast cancer), and other popular sexually transmitted diseases such as chlamydia. Genetic testing can also be done to screen for mutations that cause genetic disorders or are predisposed to certain diseases like breast cancer or ovarian cancer.

These initiatives are therefore not available to all and the cost-effectiveness of preventive healthcare is still a matter for discussion.

Primal and primordial preventionPrimordial prevention refers to measures designed to avoid the development of risk factors in the first place, early in life.
Primary preventionMethods to avoid the occurrence of disease either through eliminating disease agents or increasing resistance to disease. Examples include immunization against disease, maintaining a healthy diet and exercise regimen, and avoiding smoking.
Secondary preventionMethods to detect and address an existing disease prior to the appearance of symptoms. Examples include treatment of hypertension (a risk factor for many cardiovascular diseases), and cancer screenings.
Tertiary preventionMethods to reduce the harm of symptomatic diseases, such as disability or death, through rehabilitation and treatment. Examples include surgical procedures that halt the spread or progression of the disease.
Quaternary preventionMethods to mitigate or avoid results of unnecessary or excessive interventions in the health system

What Is Preventive Medicine?

Every day, we go through life with our own routines and our own habits. If things go wrong, we become accidents or sick, we rely on trustworthy doctors and health workers to help us recover.

This is how much health care operates — responsive steps to cure a disease or disease already in development.

But what if first of all, we could stop getting sick? This is all about preventive medicine. Most fields of medicine are based on one age group, ailment, or part of the body. However, preventive medicine doesn’t have these restrictions, making it a very large area.

What Is Preventive Medicine?

But what is medicine for prevention? Why is this so important? Continue to learn about preventive medicine and why its scope does not only include patients but various groups and populations.

What is Preventive Medicine, EXACTLY?

Preventive medicine sounds just like it — it is aimed at stopping illness before it occurs.

The philosophy behind preventive medicine focuses on health and welfare security, promotion, and maintenance. It is also intended to prevent illnesses, injuries, and death on a personal and large-scale basis in societies and populations.

All physicians advocate preventive medicine, although some prefer to specialize in it. Physicians use genetics and epidemiology and a combination of the sciences of health, social, economic, and conduct. They can assess programs of health or manage organizations of health care. They also examine the cause of illness and disability in particular parts of the population.

Preventive medicine is an interdisciplinary medicine branch that focuses on the whole patient and its multiple causes. It covers a wide spectrum that includes socio-economic aspects, the role of policy, equality in health, and the inequalities found in communities and certain groups.

Why is Preventive Medicine Important?

Seven in ten deaths are due to chronic illnesses, such as diabetes and heart disease. That’s why screening and identification are so important. Healthy behaviors are equally important, including good food, exercise, and tobacco avoidance. These help people stay healthy, prevent disease, or minimize disease effects.

CDC reports five major causes of death in the United States: heart disease, cancer, chronic low respiratory conditions, stroke, and accidental injury. CDC lists the main causes of death in the United States. In preventing premature death, preventive medicine is all the more relevant.

Practicing preventive medicine can also lower costs, as CDC estimates that 75 percent of the annual health expenditure goes to chronic diseases that are mostly preventable in the US. Preventive medicine also tackles chronic disease-related productivity drain.

Preventive Medicine Medical and non-clinical

Preventive medication can be used both in and outside the clinic. Physicians in clinical prevention medicine see patients. They will advise for bad habits, perform preventive health checks, and administer vaccinations. They may work with patients who benefit from changes in their lifestyle and often find themselves in common cases such as diabetes, smoking, or obesity.

Physicians in non-clinical preventive medicine do not deal closely with single patients. This medicine division covers health policy, epidemiology, and an emphasis on social and mental health factors. The work of many preventive medicine doctors however extends to both the clinical and non-clinical areas.

Moreover, the field of preventive medicine provides many unique subspecialties, including:


Aerospace medicine affects the health and safety of air and space cars. Passengers and staff are subject to their share of environmental and physical and psychological pressures.

Aerospace medicine physicians work to improve the health, protection, and well-being of people who work in or fly in the air and space. They focus on avoiding accidents from many environmental causes, including microgravity, exposure to radiation, G-forces, emergency ejection, and hypoxic conditions.


Occupational medicine aims at avoiding employees’ accidents, disabilities, and death. Physicians trained in occupational medicine study and analyze the health effects of physical, chemical, biological, and social conditions in the workplace. They help workers identify health and safety threats to employees and work to reduce workplace risks that could lead to injury or death. They may also make policy recommendations for the promotion of healthy work conditions, the diagnosis, and the study of occupational diseases and injuries.


The specialty in public health encourages health and well-being to a greater degree. These physicians collaborate with neighborhoods and certain groups of the population, integrating clinical expertise focused on prevention with population-based public health.

Public health professionals examine and evaluate the causes of public health issues. They also create methods to solve public health challenges, which may lead to new initiatives that improve better health and avoid disease spread. Public health professionals also address legislation for the good of the health of whole populations with other officials in the region.


You now know what preventative medicine is and how physicians integrate it or specialize in it in their practice. This is an important area of medicine that allows not only patients and communities to counteract disease but also to reduce health costs.
