PY - 2022 T2 - Maxcy-Rosenau-Last Public Health & Preventive Medicine, 16e AB - A transition in disease burden, the general notion of a shift from communicable to noncommunicable causes of disease and injury, remains a powerful framework for global and regional health policy debates.1 In 1971, Omran outlined the concept of the epidemiological transition to describe the changing pattern of causes of death that results from sociodemographic development.2 The epidemiological transition is an extension of the conception of the demographic transition. In the demographic transition, a characteristic evolution occurs in populations over time toward reduced fertility rates, reduced mortality rates, and an older-age distribution of the population. The widely used concept of the epidemiological transition adds the idea that, in addition to these changes, a characteristic change occurs in the contributing causes of death.1 The epidemiological transition has been broadened to encompass a more general health transition, including both morbidity and mortality. The developments of modern healthcare and medicine drastically reduce infant mortality rates and extend average life expectancy. These factors, coupled with subsequent declines in fertility rates, have catalyzed a transition to noncommunicable diseases (NCDs) as increasingly important causes of health loss. The notion of the epidemiological transition has also been expanded to recognize a transition phase that may lead to a double burden of disease, the growing threat of NCDs as causes of health loss while infectious diseases remain highly prevalent. Too often, the health system may continue to rely heavily on the conventional infectious disease paradigm and be unresponsive to this emerging epidemiological shift.3 SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/04/24 UR - accessmedicine.mhmedical.com/content.aspx?aid=1182682481 ER -
