Normative Aging Study
The Normative Aging Study (NAS) is a longitudinal study which studies the effects of aging on various health issues. The ongoing study was established in 1963 by the United States Department of Veterans Affairs. The initial sample was 2,280 men now with an average age of 72 years (mean age at entry was 42 years). Most participants are veterans from World War II and the Korean War. Participants in the study have undergone medical examinations every three to five years, also answering questions about behaviors affecting health. Among the topics researchers have used the NAS for are stress, smoking, and cardiac The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to t ... health. One of the findings based on the study was that subjective stress appeared to be a better prediction of mortality tha ...

Longitudinal Study
A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over short or long periods of time (i.e., uses longitudinal data). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment. Longitudinal studies are often used in social-personality and clinical psychology, to study rapid fluctuations in behaviors, thoughts, and emotions from moment to moment or day to day; in developmental psychology, to study developmental trends across the life span; and in sociology, to study life events throughout lifetimes or generations; and in consumer research and political polling to study consumer trends. The reason for this is that, unlike cross-sectional studies, in which different individuals with the same characteristics are compared, longitudinal studies track the same people, and so the differences observed in those people are less like ...

United States Department Of Veterans Affairs
The United States Department of Veterans Affairs (VA) is a Cabinet-level executive branch department of the federal government charged with providing life-long healthcare services to eligible military veterans at the 170 VA medical centers and outpatient clinics located throughout the country. Non-healthcare benefits include disability compensation, vocational rehabilitation, education assistance, home loans, and life insurance. The VA also provides burial and memorial benefits to eligible veterans and family members at 135 national cemeteries. While veterans' benefits have been provided by the federal government since the American Revolutionary War, a veteran-specific federal agency was not established until 1930, as the Veterans Administration. In 1982, its mission was extended to a fourth mission to provide care to non-veterans and civilians in case of national emergencies. In 1989, the Veterans Administration became a cabinet-level Department of Veterans Affairs. The age ...

Cardiac
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall o ...

United Press International
United Press International (UPI) is an American international news agency whose newswires, photo, news film, and audio services provided news material to thousands of newspapers, magazines, radio and television stations for most of the 20th century. At its peak, it had more than 6,000 media subscribers. Since the first of several sales and staff cutbacks in 1982, and the 1999 sale of its broadcast client list to its main U.S. rival, the Associated Press, UPI has concentrated on smaller information-market niches. History Formally named United Press Associations for incorporation and legal purposes, but publicly known and identified as United Press or UP, the news agency was created by the 1907 uniting of three smaller news syndicates by the Midwest newspaper publisher E. W. Scripps. It was headed by Hugh Baillie (1890–1966) from 1935 to 1955. At the time of his retirement, UP had 2,900 clients in the United States, and 1,500 abroad. In 1958, it became United Press Intern ...

Cohort Studies
A cohort study is a particular form of longitudinal study that samples a cohort (a group of people who share a defining characteristic, typically those who experienced a common event in a selected period, such as birth or graduation), performing a cross-section at intervals through time. It is a type of panel study where the individuals in the panel share a common characteristic. Cohort studies represent one of the fundamental designs of epidemiology which are used in research in the fields of medicine, pharmacy, nursing, psychology, social science, and in any field reliant on 'difficult to reach' answers that are based on evidence (statistics). In medicine for instance, while clinical trials are used primarily for assessing the safety of newly developed pharmaceuticals before they are approved for sale, epidemiological analysis on how risk factors affect the incidence of diseases is often used to identify the causes of diseases in the first place, and to help provide pre-clinica ...
