Goal
Improve health, fitness, and quality of life through daily physical activity.
Overview
Structural environments, such as the availability of sidewalks, bike lanes, trails, and parks
Legislative policies that improve access to facilities that support physical activity
New to Healthy People 2020 are objectives related to policies targeting younger children through:
Physical activity in childcare settings
Television viewing and computer usage
Recess and physical education in the Nation’s public and private elementary schools
Why Is Physical Activity Important?
Regular physical activity can improve the health and quality of life of Americans of all ages, regardless of the presence of a chronic disease or disability.1, 2 Among adults and older adults, physical activity can lower the risk of:
Early death
Coronary heart disease
Stroke
High blood pressure
Type 2 diabetes
Breast and colon cancer
Falls
Depression
Among children and adolescents, physical activity can:
Improve bone health.
Improve cardiorespiratory and muscular fitness.
Decrease levels of body fat.
Reduce symptoms of depression.
For people who are inactive, even small increases in physical activity are associated with health benefits.
Understanding Physical Activity
Personal, social, economic, and environmental factors all play a role in physical activity levels among youth, adults, and older adults. Understanding the barriers to and facilitators of physical activity is important to ensure the effectiveness of interventions and other actions to improve levels of physical activity.
Factors positively associated with adult physical activity include:
Postsecondary education
Higher income
Enjoyment of exercise
Expectation of benefits
Belief in ability to exercise (self-efficacy)
History of activity in adulthood
Social support from peers, family, or spouse
Access to and satisfaction with facilities
Enjoyable scenery
Safe neighborhoods
Factors negatively associated with adult physical activity include:
Advancing age
Low income
Lack of time
Low motivation
Rural residency
Perception of great effort needed for exercise
Overweight or obesity
Perception of poor health
Being disabled
Older adults may have additional factors that keep them from being physically active, including lack of social support, lack of transportation to facilities, fear of injury, and cost of programs.
Among children ages 4 to 12, the following factors have a positive association with physical activity:
Gender (boys)
Belief in ability to be active (self-efficacy)
Parental support
Among adolescents ages 13 to 18, the following factors have a positive association with physical activity:
Parental education
Gender (boys)
Personal goals
Physical education/school sports
Belief in ability to be active (self-efficacy)
Support of friends and family
Environmental influences positively associated with physical activity among children and adolescents include:
Presence of sidewalks
Having a destination/walking to a particular place
Access to public transportation
Low traffic density
Access to neighborhood or school play area and/or recreational equipment
People with disabilities may be less likely to participate in physical activity due to physical, emotional, and psychological barriers. Barriers may include the inaccessibility of facilities and the lack of staff trained in working with people with disabilities.
Emerging Issues in Physical Activity
Healthy People 2020 reflects a multidisciplinary approach to promoting physical activity. This approach brings about traditional partnerships, such as that of education and health care, with nontraditional partnerships representing, for example, transportation, urban planning, recreation, and environmental health. (For more information, see Web Site Policy.) Several new objectives reflect this emphasis—for example, physical activity policies regarding childcare (Objective 2020-9) and environmental settings (Objective 2020-15).
Data sources that are representative of the entire Nation are needed to monitor key characteristics of the environment, such as the availability of parks and trails, the usage of these spaces, and policies that promote physical activity at worksites, in communities, and in schools.
