Goal 1: Increase
Quality and Years of Healthy Life - The first goal of Healthy People 2010 is
to help individuals of all ages increase life expectancy and improve their
quality of life.
|
|
Life Expectancy -
Life expectancy is the average number of years people born in a given year
are expected to live based on a set of age-specific death rates. At the
beginning of the 20th century, life expectancy at birth was 47.3 years.
Fortunately, life expectancy has increased dramatically over the past 100
years (see figure 1). Today, the average life expectancy at birth is nearly
77 years.
|
|
Life expectancy for persons
at every age group also has increased during the past century. Based on
today’s age-specific death rates, individuals aged 65 years can be expected
to live an average of 18 more years, for a total of 83 years. Those aged 75
years can be expected to live an average of 11 more years, for a total of 86
years.
|
|
Differences in life
expectancy between populations, however, suggest a substantial need and
opportunity for improvement. At least 18 countries with populations of 1
million or more have life expectancies greater than the United States for
both men and women (see figure 2).
|
|
There are substantial
differences in life expectancy among different population groups within the
United States. For example, women outlive men by an average of 6 years. White
women currently have the greatest life expectancy in the United States. The
life expectancy for African American women has risen to be higher today than
that for white men. People from households with an annual income of at least
$25,000 live an average of 3 to 7 years longer, depending on gender and race,
than do people from households with annual incomes of less than $10,000.

Quality of Life -
Quality of life reflects a general sense of happiness and satisfaction with
our lives and environment. General quality of life encompasses all aspects of
life, including health, recreation, culture, rights, values, beliefs,
aspirations, and the conditions that support a life containing these
elements. Health-related quality of life reflects a personal sense of
physical and mental health and the ability to react to factors in the
physical and social environments. Health-related quality of life is more
subjective than life expectancy and therefore can be more difficult to
measure. Some tools have been developed to measure health-related quality of
life.
|
|
Global assessments, in which
a person rates his or her health as “poor,” “fair,” “good,” “very good,” or
“excellent,” can be reliable indicators of one’s perceived health. In 1996,
90 percent of people in the United States reported their health as good, very
good, or excellent.
|
|
Healthy days is another
measure of health-related quality of life that estimates the number of days
of poor or impaired physical and mental health in the past 30 days. In 1998,
adults averaged 5.5 days during the past month when their physical or mental health
was not good—including 1.8 days when they were not able to do their usual
activities. However, 52 percent of adults reported having good physical and
mental health for the entire month in contrast with 10 percent of adults who
were unhealthy for all 30 days. Typically, younger adults report more
mentally unhealthy days while older adults report more physically unhealthy
days.
|
|
Years of healthy life
is a combined measure developed for the Healthy People initiative. The
difference between life expectancy and years of healthy life reflects the
average amount of time spent in less than optimal health because of chronic
or acute limitations. Years of healthy life increased in 1996 to 64.2 years,
a level that was only slightly above the 64.0 years at the beginning of the
decade. During the same period, life expectancy increased a full year.
|
|
As with life expectancy,
various population groups can show dramatic differences in quality of life.
For example, people in the lowest income households are five times more
likely to report their health as fair or poor than people in the highest
income households (see figure 3). A higher percentage of women report their
health as fair or poor compared to men. Adults in rural areas are 36 percent
more likely to report their health status as fair or poor than are adults in
urban areas.

Achieving a Longer and
Healthier Life—the Healthy People Perspective - Healthy People 2010 seeks
to increase life expectancy and quality of life over the next 10 years by
helping individuals gain the knowledge, motivation, and opportunities they
need to make informed decisions about their health. At the same time, Healthy
People 2010 encourages local and State leaders to develop communitywide and
statewide efforts that promote healthy behaviors, create healthy
environments, and increase access to high-quality health care. Because
individual and community health are virtually inseparable, both the
individual and the community need to do their parts to increase life
expectancy and improve quality of life.
