Abbreviated Name:

Indicator Name:
Age-standardized prevalence of insufficiently physically active persons aged 13-18 years
Domain:
Health determinants and risks / Risk factors
Related Terms:
Non-communicable diseases, risk factors, adolescent health
Definition:
Age-standardized prevalence of insufficiently physically active persons aged 13-18 years (percentage of adults aged 13-18 years not meeting any of
the following criteria: 150 minutes of moderate-intensity physical activity per week; 75 minutes of vigorous-intensity physical activity per week;
an equivalent combination of moderate- and vigorous-intensity physical activity accumulating at least 600 metabolic equivalent minutes per week
(minutes of physical activity can be accumulated over the course of a week but must be of a duration of at least 10 minutes).
*Metabolic equivalent (MET) is the ratio of a person’s working metabolic rate relative to the resting metabolic rate. One metabolic equivalent
is defined as the energy cost of sitting quietly and is equivalent to a caloric consumption of 1 kcal/kg per hour. Physical activities are frequently
classified by their intensity, using the metabolic equivalent as a reference.

Measurment Method:
(Number of respondents aged 18+ years not meeting the aforementioned criteria for physical activity)/(number of survey respondents aged 13-18 years) x 100.
Numerator:
Number of respondents where all three of the following criteria are true:
weekly minutes* of vigorous activity < 75 minutes;
weekly minutes* of moderate activity < 150 minutes;
weekly metabolic equivalent minutes** < 600.
* Weekly minutes are calculated by multiplying the number of days on which vigorous/moderate activity is done by the number of minutes of vigorous/moderate activity per day.
** Weekly metabolic equivalent minutes are calculated by multiplying the weekly minutes of vigorous activity by 8 and the number of weekly minutes of moderate activity by 4 and then adding these two results together.
weekly minutes* of vigorous activity < 75 minutes;
weekly minutes* of moderate activity < 150 minutes;
weekly metabolic equivalent minutes** < 600.
