In the Name of God
The goal of the Community Medicine Department is to train healthcare personnel and physicians who pay attention to the affairs relating to diseases and health by considering social conditions. A community physician is a healthcare professional who has a holistic perspective toward the community based on the three specialized preventative levels of community medicine (healthy, diseased and disabled); this is due to the fact that human health is influenced by several social, economic, cultural and lifestyle factors in addition to health-related personal parameters. As such, community medicine encompasses a wide variety of specialized activities, imposing a great responsibility on the physicians.
On the other hand, the "iceberg phenomenon" shows that many influential factors in human health remain unclear, and healthy individuals are not distinguished properly from patients in the latent stages of a disease. Furthermore, community physicians often operate in the hidden stages of diseases in the community, which detracts attention from their endeavors and these groups of professionals are neglected even by the officials and policy makers.
Today, only a few believe in the fact that prevention is better than cure since the three preventative levels of treatment are also considered a measure of disease prevention (i.e., secondary prevention). Therefore, if preserving the health of individuals is not possible initially, the next stage of healthcare might revolve around the diagnosis and treatment of the disease (second level of prevention).
The process of care encompasses health services before the development of the disease, treatment, and healthcare services after the occurrence of the disease, even during the disabled stage (care not only cure). Moreover, the concept of "self-care" has been recognized as an important determinant of human health, which focuses on aspects such as healthy lifestyle through increasing physical activity, proper nutrition, avoidance of smoking and narcotics, safe sexual behaviors, and reduced violence.
It is also noteworthy that self-care behaviors do not only represent physical health care, but rather the care of oneself in thoughts, speech and actions, which account for the mental health of an individual.
