Indicator: 12 Youth Physical Activity

Why This Is Important
Lack of enough physical activity is a critical health related risk
factor. Lack of physical activity can contribute to a young person
being overweight, impair development of bones and muscles, and result
in increased levels of stress.
Where We Stand
Sixty-six percent of the high school-aged respondents to the 2001
Maine Youth Risk Behavior Survey indicated that they had exercised
or participated in physical activities that made them sweat and
breathe hard for at least 20 minutes on three or more of the past
seven days. Older teens reported slightly lower rates of such vigorous
exercise than younger ones, and boys reported higher rates than
girls (71% versus 61%). Twenty-nine percent of the youth reported
that they exercised moderately (defined as engaging in physical
activities that did not make them sweat or breathe hard for at least
30 minutes on five or more of the previous seven days).

Data Sources and Context
This information comes from the Maine Youth Risk Behavior Survey
(YRBS), Maine Department of Education. The data source is the Youth
Risk Behavior Surveillance System maintained by the U.S. Centers
for Disease Control and Prevention (CDC). Data from the Maine YRBS
is available on-line at http://www.mainecshp.com/survey.html.
National YRBS figures can be found at http://www.cdc.gov/nccdphp/yrbs/index.htm.
*Important Note: YRBS data is gathered every two
years using a questionnaire administered to a sample of students
in Maine and nationally. When the Maine YRBS survey has an overall
response rate of 60% or higher, the CDC statistically weights the
results so that the numbers can be generalized to all public school
students in the state in grades 9-12. When the overall response
rate is below 60%, the CDC does not perform such statistical weighting,
and the data apply only to the students who actually filled out
the questionnaires. Maine's YRBS data for 1999 was unweighted, so
information from that year cannot be compared reliably with data
from 1995, 1997 and 2001.
