Louis, Missouri Corresponding author: Introduction During the past century in the United States, advances in public health and health care have increased life expectancy by approximately 30 years and led to dramatic changes in the leading causes of death 1.
As chronic diseases became the leading causes of illness and death in the United States by the middle of the 20th century 2public health researchers began to shift their focus to identifying their complex and interrelated causes.
In addition, researchers began to study ways to prevent and control chronic diseases through clinical and community-based interventions. Considerable progress has been made during the past 50 years in understanding the causes of chronic diseases, as well as in development of the evidence for effective strategies to prevent, detect, or control chronic diseases 3.
This report focuses on progress in four areas by: Describing progress in understanding the causes of chronic disease through epidemiologic research; Describing advances in understanding the evidence base for prevention and control, through intervention research; Assessing the impact of these advances on the prevalence of chronic diseases in the United States, as measured by reductions in chronic disease morbidity and mortality; and Discussing the lessons learned during the past 50 years in translating this research into practice in the United States.
This report provides a synopsis of progress by using key examples within the four areas rather than an exhaustive review of chronic disease epidemiology and control during the past half-century.
These studies elucidated the contributions of cigarette smoking, diet, physical inactivity, and high blood pressure to the leading causes of death.
Over 50 years or more, these and other studies have helped establish the behavioral causes of many of the chronic diseases affecting humans. None of these studies has established the causes of any chronic disease by itself; rather, the causes have been established on the basis of a large number of studies that used different designs and were conducted in different populations 5.
The discovery that smoking caused lung cancer can be viewed as the first and most important advance in chronic disease etiology. The results from the first studies of lung cancer were summarized in the first Surgeon General's Report on Smoking and Health, published in Establishment of the "criteria for causality" in this report was critical in the evolution of the understanding of the causes of chronic disease, given the long latency between exposures and outcomes; the multiple causes of chronic diseases; and the multiple consequences of many of the risk factors.

These criteria, subsequently called the "Hill criteria," would continue to be used over time to consider the causal risk factors for other chronic diseases 6.
During and after the s, researchers continued to study the relationship between risk factors e. For example, the "diet--heart" hypothesis was tested in observational studies such as the Framingham Heart Study, a prospective cohort study of residents of Framingham, Massachusetts 4.
At the same time, researchers shifted their focus from chronic diseases to the behavioral risk factors preceding the diseases. These researchers used the results from decades of epidemiologic research to demonstrate that approximately half of all deaths could be attributed to relatively few risk factors; their work was updated later by Mokdad 8 Table 1.
Inthe Canadian Lalonde Report 9 concluded that the health of a population could be considered in four broad elements: This model of the "multiple determinants of health" provides a broad conceptual framework for considering the factors that influence health in a community Belie fs and practices concerning death have changed throughout human history.
In pre modern times, death at a young age was common due to living co nditions and medical practices. As medical science has advanced and helped humans live longer, attitudes and responses to death also have changed.

There was no specific treatment for heart disease at the time – no coronary care unit in the hospital, stents, angioplasty, pacemakers.
Mental Health America organized the National Action Commission on the Mental Health of Rural Americans to study service and policy issues regarding the delivery of mental health services to citizens living in rural areas whose lives have been impacted by major social and economic change.
In the past years, social and technological changes have drastically changed the way in which patients are treated in hospitals for the better. Until the late s, hospitals were largely.
