Each year, millions of people die of preventable deaths. A 2004 study showed that about half of all deaths in the Public health and preventive medicine in canada pdf States in 2000 were due to preventable behaviors and exposures. There are many methods for prevention of disease. It is recommended that adults and children aim to visit their doctor for regular check-ups, even if they feel healthy, to perform disease screening, identify risk factors for disease, discuss tips for a healthy and balanced lifestyle, stay up to date with immunizations and boosters, and maintain a good relationship with a healthcare provider.
Preventive healthcare strategies are described as taking place at the primal, primary, secondary, and tertiary prevention levels. Gurney Clark coined the term primary prevention. They worked at the Harvard and Columbia University Schools of Public Health, respectively, and later expanded the levels to include secondary and tertiary prevention. Primordial prevention refers to measures designed to avoid the development of risk factors in the first place, early in life. Methods to avoid 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.
Methods to detect and address an existing disease prior to the appearance of symptoms. Methods to reduce the harm of symptomatic disease, such as disability or death, through rehabilitation and treatment. A separate category of “health promotion” has recently been propounded. This health promotion par excellence is based on the ‘new knowledge’ in molecular biology, in particular on epigenetic knowledge, which points to how much affective – as well as physical – environment during fetal and newborn life may determine each and every aspect of adult health. Another related concept is primordial prevention which to refers to all measures designed to prevent the development of risk factors in the first place, early in life.
Primary prevention consists of traditional “health promotion” and “specific protection. Health promotion activities are current, non-clinical life choices. For example, eating nutritious meals and exercising daily, that both prevent disease and create a sense of overall well-being. Food is very much the most basic tool in preventive health care.
The 2011 National Health Interview Survey performed by the Centers for Disease Control was the first national survey to include questions about ability to pay for food. Difficulty with paying for food, medicine, or both is a problem facing 1 out of 3 Americans. Scientific advancements in genetics have significantly contributed to the knowledge of hereditary diseases and have facilitated great progress in specific protective measures in individuals who are carriers of a disease gene or have an increased predisposition to a specific disease. Secondary prevention deals with latent diseases and attempts to prevent an asymptomatic disease from progressing to symptomatic disease. Certain diseases can be classified as primary or secondary.
Finally, tertiary prevention attempts to reduce the damage caused by symptomatic disease by focusing on mental, physical, and social rehabilitation. Unlike secondary prevention, which aims to prevent disability, the objective of tertiary prevention is to maximize the remaining capabilities and functions of an already disabled patient. The leading cause of death in the United States was tobacco. However, poor diet and lack of exercise may soon surpass tobacco as a leading cause of death. These behaviors are modifiable and public health and prevention efforts could make a difference to reduce these deaths. The leading causes of preventable death worldwide share similar trends to the United States.
There are a few differences between the two, such as malnutrition, pollution, and unsafe sanitation, that reflect health disparities between the developing and developed world. 6 million children died before reaching the age of 5. While this is a decrease from 9. 6 million in the year 2000, it is still far from the fourth Millennium Development Goal to decrease child mortality by two-thirds by the year 2015. Child mortality is caused by a variety of factors including poverty, environmental hazards, and lack of maternal education. Obesity is a major risk factor for a wide variety of conditions including cardiovascular diseases, hypertension, certain cancers, and type 2 diabetes.
In order to prevent obesity, it is recommended that individuals adhere to a consistent exercise regimen as well as a nutritious and balanced diet. STIs are common both in history and in today’s society. STIs can be asymptomatic or cause a range of symptoms. Condom and other barrier use reduces the risk of acquiring some STIs.
Thrombosis is a serious circulatory disease affecting thousands, usually older persons undergoing surgical procedures, women taking oral contraceptives and travelers. Consequences of thrombosis can be heart attacks and strokes. Prevention can include: exercise, anti-embolism stockings, pneumatic devices, and pharmacological treatments. In recent years, cancer has become a global problem. Low and middle income countries share a majority of the cancer burden largely due to exposure to carcinogens resulting from industrialization and globalization. However, primary prevention of cancer and knowledge of cancer risk factors can reduce over one third of all cancer cases.
