Epidemiologic Transition




TheTable representing mortality burden in 1900 differs from the oneportraying mortality burden in 2005 in that, the major causes ofdeath in the former figure is composed of infectious diseases. Thisimplies that the diseases are either passed from one generation tothe other through family genetics such as tuberculosis, or anindividual’s physical environment may predispose them to diseasessuch as pneumonia. On the other hand, the major cause of death inyear 2005 is chronic lifestyle diseases such as heart attacks andmalignant neoplasm (McKeown, 2010).

Oneof the key contributors of mortality epidemiologic transitionexperienced between1900 and 2005 is the discovery of advanced medicalcare solutions. For example, several diseases such as pneumonia andtuberculosis are effectively regulated using antibiotics. Extensiveresearch has also identified common causes of the diseases, therebyeducating the public on efficient ways of refraining from acquiringthe illnesses (McKeown, 2010).

Second,lifestyle changes have also contributed to the epidemiologictransition experienced in 2005. For example, highly processed dietsoften contain limited fiber and healthy nutrients the body requiresfor healthy functions such as building immunity. The result of poordieting habits has led to the increased number of persons sufferingfrom lethal diseases associated with lifestyle adjustments. In 1900,many people were consuming natural whole foods that are rich invaluable nutrients required in protecting the body against commondiseases (McKeown, 2010).

Lastly,advanced medical sociology has helped in reducing the overall numberof patients that die from the disease-related complications. Themedical sociology refers to the study of medical institutions andorganizations, healthcare professionals’ actions and interactions,the knowledge selection and production methods, and the cultural orsocial impact of medical practices. Presently, many people areempowered with information concerning living healthy lifestyles. Thisenables them to choose from a wide range of suitable treatmentoptions proven to treat given medical conditions. Furthermore,vulnerable patients to diseases such as malignant neoplasm and heartconditions can benefit from several studies that offer guidance onmethods of controlling the diseases (McKeown, 2010).
