FACT

PHYSICAL
ACTIVITY AND HEALTH
(Citation:
U.S. Department of Health and Human Services. The following facts are
based on information from publications prepared by agencies and offices
of the Department of Health and Human Services: the Centers for Disease
Control and Prevention; the National Center for Health Statistics; the
Office of the Surgeon General of the United States (Physical Activity
and Health, 1996; Call to Action to Prevent and Decrease Overweight and
Obesity, 2001), and the Office of Disease Prevention and Health Promotion
(Healthy People 2010, 2001).
- Physical
inactivity contributes to 400,000 preventable deaths (17% of total deaths)
a year in the United States. More than 40% of deaths in the United States
are caused by behavior patterns that could be modified. A sedentary
lifestyle is a major risk factor across the spectrum of preventable
diseases that lower the quality of life and kill Americans. Poor diet
and physical inactivity (combined) are rapidly approaching tobacco (435,000
deaths) as the leading cause of preventable death in the US.
- Adults
18 and older need 30 minutes of physical activity on five or more days
a week to be healthy; children and teens need 60 minutes of activity
a day for their health.
- Significant
health benefits can be obtained by including a moderate amount of physical
activity (e.g., 30 minutes of brisk walking or raking leaves, 15 minutes
of running, 45 minutes of playing volleyball). Additional health benefits
can be gained through greater amounts of physical activity.
- Thirty
to sixty minutes of activity broken into smaller segments of 10 or 15
minutes throughout the day has significant health benefits.
- Moderate
daily physical activity can reduce substantially the risk of developing
or dying from cardiovascular disease, type 2 diabetes, and certain cancers,
such as colon cancer. Daily physical activity helps to lower blood pressure
and cholesterol, helps prevent or retard osteoporosis, and helps reduce
obesity, symptoms of anxiety and depression, and symptoms of arthritis.
- Cardiovascular
disease (heart attacks, strokes) is the number one killer of men and
women in the United States. Physically inactive people are twice as
likely to develop coronary heart disease as regularly active people.
The health risk posed by physical inactivity is almost as high as risk
factors such as cigarette smoking, high blood pressure, and high cholesterol.
- Nearly
half of American adults (4 in 10) report that they are not active at
all; 7 in 10 are not moderately active for the recommended 30 minutes
a day, 5 or more days a week.
- Poor diet
and inactivity can lead to overweight/obesity. Persons who are overweight
or obese are at increased risk for high blood pressure, type 2 diabetes,
coronary heart disease, stroke, gallbladder disease, osteoarthritis,
sleep apnea, respiratory problems and some types of cancer.
- Poor diet
and inactivity can lead to diabetes. Seventeen million Americans have
diabetes right now and 16 million more have pre-diabetes. Each year,
there are 1 million new cases and 200,000 people die from diabetes.
The cost to the economy is $132 billion annually in direct and indirect
medical costs.
- Obesity
continues to climb among American adults. Nearly 50 million Americans
are obese. More than 108 million adults are either obese or overweight.
That means roughly 3 out of 5 Americans carry an unhealthy amount of
excess weight. The cost of obesity (direct and indirect medical costs)
is $117 billion per year.
- The percentage
of adults in the United States who were overweight or obese (body mass
index greater than 25) in 1999 was 61%. Overweight and obesity cuts
across all ages, racial and ethnic groups, and both genders. A new study
in the Netherlands found that excess weight cuts years off your life.
- Overweight
among children and teens has doubled in the past two decades; 15% of
children aged 6 to 11 years and 15% of adolescents aged 12 to 19 years
were overweight in 2000. This prevalence has nearly tripled for adolescents
in the past 2 decades. The percentage of overweight African American,
Hispanic, and Native American children is about 20%.
- Among children
and teens, almost 9 million are overweight, triple the proportion in
1980. More than 10 percent of children between the ages of 2 and 5 are
overweight, double the proportion since 1980.
- The cost
of overweight and obesity to the economy is $117 billion annually in
direct and indirect medical costs.
- Health
risks associated with being overweight or obese include type 2 diabetes,
high blood pressure, high cholesterol, asthma, arthritis.
- The major
barriers most people face when trying to increase physical activity
are time, access to convenient facilities, and safe environments in
which to be active.
- School-based
and workplace based interventions have been shown to be successful in
increasing physical activity levels.
- Childhood
and adolescence are pivotal times for preventing sedentary behavior
among adults by maintaining the habit of physical activity throughout
the school years.
- Type 2
diabetes, once called "adult onset" diabetes, high blood pressure,
and high cholesterol, once thought to be age-related, are now diagnosed
in children and teens.
- Physical
activity among children and adolescents is important because of the
related health benefits (cardio-respiratory function, blood pressure
control, weight management, cognitive and emotional benefits).
- Only about
one-half of U.S. young people (ages 12-21 years) regularly participate
in vigorous physical activity. One-fourth reported no vigorous physical
activity. About 14 percent report no recent vigorous or light-to-moderate
activity.
- A physically
active lifestyle adopted early in life may continue into adulthood.
Even among children aged 3 and 4 years, those who were less active tended
to remain less active than most of their peers after age 3 years. According
to a study done by the National Association of Sports and Physical Education
(NASPE), infants, toddlers, and pre-schoolers should engage in at least
60 minutes of physical activity daily and should not be sedentary for
more than 60 minutes at a time except when sleeping.
- One quarter
of U.S. children spend 4 hours or more watching television daily.
- Young people
are at particular risk for becoming sedentary as they grow older. Encouraging
moderate and vigorous physical activity among youth is important. Because
children spend most of their time in school, the type and amount of
physical activity encouraged in schools are important.
- Only 20
percent of students in grades 9 through 12 engaged in moderate physical
activity for at least 30 minutes on 5 or more of the previous 7 days
in 1997.
- Only 29
percent of students in grades 9 through 12 participated in daily school
physical education in 1999, down from 42 percent in 1991.
- Only 17
percent of middle and junior high school and 2 percent of senior high
schools require daily physical activity for all students.
