Aging

Aging

Q 1

Gerontology is the study of the aging processes and individuals as they grow from middle age through later life.

Geriatrics is

the study of health and disease in later life

the comprehensive health care of older persons and the well-being of their informal caregiver

Q 2

Aging, or senescence, is the major cause of suffering, disease, and death in Western civilization. Gerontology, also called biogerontology, is the science that studies the aging process to prevent age-related disease and degeneration, preserve health, and prolong human life.

Q 3

Active ageing applies to both individuals and population groups. It allows people to realize their potential for physical, social, and mental well being throughout the life course and to participate in society according to their needs, desires and capacities, while providing them with adequate protection, security and care when they require assistance.

Methodology

Q 1

As the population continues to age, gerontological research will become increasingly important and library holdings in gerontology and geriatrics will be in great demand (Croake Myers & Singh 2008 46).

Q 2

A cross-sectional study is a descriptive study in which disease and exposure status are measured simultaneously in a given population. Longitudianl study is a correlational research study that involves repeated observations of the same items over long periods of time — often many decades. It is a type of observational study.

Q 3

Longitudinal surveys differ greatly from the collection of repeated cross-sectional data in which an independent sample is collected at each wave to represent the population for that time period. With cross-sectional data, the observed trip information is representative of the population at a single period in time and the temporal aspects of a specific individual's travel are not necessarily available (Geise 1999 51).  

Q 4

Age is the accumulation of changes in an organism or object over time. is a group of people who share a common characteristic or experience within a defined period (e.g., are born, leave school, lose their job, are exposed to a drug or a vaccine, etc.) Period is the specific course of time.

Demographics

Q 1

The older population--persons 65 years or older--numbered 37.3 million in 2006 (the latest year for which data is available). They represented 12.4% of the U.S. population, about one in every eight Americans. By 2030, there will be about 71.5 million older persons, more than twice their number in 2000. People 65+ represented 12.4% of the population in the year 2000 but are expected to grow to be 20% of the population by 2030. The age ...
