A) As sitting increases, activity levels also increase
B) As intense activity increases, risk of premature death increases
C) As weekly minutes of activity increases, risk of premature death decreases

A) 6 months
B) 1.4 years
C) 3 years
D) 10 years

Question 6

B) North America
C) Africa
D) Eastern Mediterranean

B) Intensive behavioral counseling for overweight adults
C) Short counseling about television viewing in adolescents
D) No counseling about either weight or physical activity

Question 8

B) Environmental and policy approach
C) Regulatory strategies
D) Educational initiatives

Question 9

"Shape Up Somerville," "Healthy Living Cambridge Kids," and "Project U-Turn," are all examples of:

A) Individual approaches to improve fitness
B) Clinical and public health linkages to reduce obesity

Question 10

A) Improved employee performance
B) Variations in productivity
C) Decreased employee turnover
D) Reduced workplace sitting

Question 11

According to medical experts, more than 30 chronic conditions may be related to regular and prolonged sitting.

Question 12

Most people in the United States sit for at least 8 hours each day.

Question 13

The relationship between sitting time and risk of death is mitigated by the level of overall physical activity.

Question 14

More than 30% of high school students are active for at least one hour each day.

Question 15

According to CDC, fewer than half of all U.S. adults are following recommendations for 150 minutes of moderate physical activity each week.

Question 16

Moderate-intensity physical activity for 150 minutes per week can reduce risk for premature death and more minutes of exercise confer greater benefit.

Question 17

The same health benefits from regular moderate physical activity is also seen in people with mobility disabilities.

Question 18

In studies looking at the relationship between weight and fitness level on risk of death, fitness was more important than weight.

Question 19

Some researchers term metabolic changes observed in individuals and populations who sit for prolonged periods as "active physiology."

Question 20

The Community Preventive Services Task Force recommends behavior change programs for individuals and improved school-based programs to increase physical activity.

Question 21

There is evidence that creating spaces to be activity, such as walking and biking trails, can improve community activity levels.

Question 22

Many evidence-based approaches to improve physical activity are closely linked to health care.

Question 23

CDC recommends evidence-based strategies in communities, worksites, schools and for individuals to increase physical activity.

Question 24

The evidence for adverse health outcomes from physical inactivity is largely cross-sectional and anecdotal.

Question 25

Globally, only about 10% of adults are physically inactive.

Question 26

Which of the following are health benefits from regular physical activity?

A) Reduced risk of premature death

A) Africa
B) Europe
C) Asia
D) South America

A) Risk of death increased as time spent sitting increased
B) Risks from sitting were independent of overall activity levels
C) Risks are seen only in older women
D) Highest risks were seen in people sitting more than 20 hours per week
