What is meant by compression of morbidity quizlet?
Compression of Morbidity. -A shortening of the time a person spends ill or infirm before death; accomplished by postponing illness. -Due to improvements in lifestyle, medicine, and technological aids.
What is the compression of morbidity thesis?
The Compression of Morbidity hypothesis—positing that the age of onset of chronic illness may be postponed more than the age at death and squeezing most of the morbidity in life into a shorter period with less lifetime disability—was introduced by our group in 1980.
What does Compressed mortality mean?
Compression of mortality is a reduction over time in the variance of age at death. Such reductions are generally accompanied by increases in the mean age at death; otherwise, for the variances to decrease, the death rates above the mean age at death would need to increase, and this has rarely been the case.
Who came up with compression of morbidity?
James Fries
The compression of morbidity in public health is a hypothesis put forth by James Fries, professor of medicine at Stanford University School of Medicine. The hypothesis was supported by a 1998 study of 1700 University of Pennsylvania alumni over a period of 20 years.
Which is the main idea of compression of morbidity quizlet?
-The idea behind compression of morbidity is to squeeze or compress the time horizon between the onset of chronic illness or disability and the time in which a person dies.
Which of the following is considered a Hypokinetic disease?
Thus hypokinetic disease is a condition associated with too little physical activity or exercise. Examples include heart disease, low back pain, and Type II diabetes. This is the most important one.
Which of the following refers to the concept compression of illness?
-Mortality means death. Define compression of morbidity and relate it to active life expectancy, and dependent life expectancy. -The idea behind compression of morbidity is to squeeze or compress the time horizon between the onset of chronic illness or disability and the time in which a person dies.
What is expansion of morbidity?
The “expansion of morbidity” scenario anticipates an increase in the life expectancy and an increase in the proportion of life spent with underlying illness or disability. 4 5. This is achieved when medical advances reduce mortality and case fatality but the disease patterns remain the same.
What is the compression of morbidity and why is it desirable?
This theory states that “most illness was chronic and occurred in later life and postulated that the lifetime burden of illness could be reduced if the onset of chronic illness could be postponed and if this postponement could be greater than increases in life expectancy.” (Fries, 1980). Figure 1.
Which of the following is defined as the inability of the heart muscle to pump blood at a life sustaining rate?
Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood to meet the body’s needs for blood and oxygen.
What is Hypokinetic disease mean?
Since “hypo” means too little, and “kinetic” means movement, the term hypokinetic means too little movement or activity. Thus hypokinetic disease is a condition associated with too little physical activity or exercise. Examples include heart disease, low back pain, and Type II diabetes.
What is the relationship between disability and compression of morbidity?
Under the compression of morbidity hypothesis, disability would be lower and acceleration in the rate of change (increased slope) closer to the time of death in a lower compared with a higher risk group.
What is the expansion of mortality?
Current mortality patterns suggest an “expansion,” rather than compression, of mortality at the oldest ages. Further refinement of these observations, with improved data on mortality among the oldest old, will be helpful in delineating mortality patterns.
What is the definition of morbidity quizlet?
morbidity. Morbidity refers to illness or disease, so the morbidity rate refers to the number of cases of illness or disease over a period of time.
What is hypokinetic?
Hypokinesia is when your movements are not as wide-ranging as they normally should be. It is often considered part of bradykinesia — a condition in which your movements are very slow. Bradykinesia can also include akinesia, where there is no movement.
