Physical inactivity in adults (Indicator 7)
The indicator describes the following: The proportion of adults who are insufficiently physically active, defined as fewer than 150 minutes of moderate to vigorous intensity activity per week.
The indicator describes the following: The proportion of adults who are insufficiently physically active, defined as fewer than 150 minutes of moderate to vigorous intensity activity per week.
This indicator is part of Target (3): A 10 per cent reduction in insufficient physical activity.
The indicator is based on device-based measurement of physical activity using accelerometers and self-reported physical activity using questionnaires. It describes the proportion of physically inactive adults (aged 20-85 years), defined as not meeting national recommendations for physical activity.
Results
Around 70 per cent of adults are categorised as physically inactive based on device-measured physical activity, compared to around 30 per cent based on self-reporting. These data are derived from national surveillance systems, (Norwegian National Physical Activity Survey, NNPAS) conducted in 2008/09 and 2014/15 (Figures 1 and 2).
In the period from 2008/09 until 2014/15 there was a small but statistically significant decline in the proportion of adults who were categorised as physically inactive based on device measurements (Figure 1), while data based on the questionnaire indicate a small increase in the proportion of physically inactive adults (Figure 2).

Data sources
The data source for this indicator is the Norwegian National Physical Activity Survey (NNPAS1 and NNPAS2).
A description and definitions of the NNPAS Studies follow below.
Data source: The NNPAS Studies
Description
NNPAS1 and NNPAS2 were conducted in representative samples of adults and the elderly in Norway (ages 20-85) in 2008/09 (N=3464; 32 per cent participation) and 2014/15 (N=3173; 29 per cent participation). The study assessed physical activity using a questionnaire (International Physical Activity Questionnaire, IPAQ) and a device-based method of measuring physical activity (accelerometry). The NNPAS Studies were conducted by the Norwegian School of Sport Sciences and commissioned by the Norwegian Directorate of Health.

Effect measure
- The proportion not meeting the physical activity recommendations by device-based measurement using accelerometers, among adults aged 20-85, as a percentage
The participants in the study were categorised as meeting the recommendations for physical activity as assessed by accelerometers, if they satisfied the following criteria:
- 150 minutes per week of moderate-intensity activity, operationalised as an average of at least 21.4 minutes of moderate-intensity activity per day, in consecutive intervals of at least 10 minutes duration, or
- 75 minutes of vigorous physical activity, operationalised as an average of at least 10.7 minutes of vigorous intensity activity per day, in consecutive intervals of at least 10 minutes’ duration, or
- a combination of moderate and vigorous-intensity activity exceeding 150 minutes per week
The figures and tables show the proportion not meeting these recommendations for physical activity. The data are not age-standardised.
- The proportion not meeting the physical activity recommendations in questionnaire responses, among adults aged 20-85, as a percentage
The participants completed the IPAQ questionnaire which is designed to categorise individuals into different activity categories in relation to the recommendations for physical activity. In accordance with the protocol developed for IPAQ, one of the three criteria must be satisfied in order to meet the recommendations for physical activity:
- Three or more days of vigorous physical activity for a minimum of 20 minutes per day
- Five or more days of moderate physical activity and/or walking for a minimum of 30 minutes per day
- Five or more days with a combination of walking, moderate or vigorous physical activity, exceeding a total activity level of at least 600 MET-minutes per week
The figures and tables show the proportion not meeting these recommendations for physical activity. The data are not age-standardised.
Interpretation and sources of error
Measurement of physical activity by self-report may be prone to misclassification bias due to over-reporting. Device measured physical activity using accelerometers is independent from an active response by participants and provides valid and reliable estimates of physical activity. A key weakness of accelerometers is that some activities are not captured (e.g. cycling).
Data quality
Device-based measures of physical activity using accelerometers provides high quality data. Self-reported data appears to produce substantially higher prevalence data, likely due to over-reporting. To make an international comparison, self-reported data are currently the only type of data available since very few countries have nationally representative data on physical activity measured by a device-based method.
The proportion of individuals who took part in NNPAS 1 and NNPAS2 is low: around 30 per cent of those invited participated. A low participation rate leads to greater uncertainty as to whether the results are representative for the entire population of Norway.

National adaptation to global indicators
WHO’s definition of the indicator
Indicator 7. Age-standardised prevalence of physically active persons aged 18+ years (defined as less than 150 minutes of moderate-intensity activity per week, or equivalent).
National adaptation
WHO’s indicator is based on self-reporting. We present both measurement data based on device measured physical activity using accelerometers and data based on self-report (International Physical Activity Questionnaire).
The data shown are representative of the age distribution in the Norwegian National Physical Activity Survey (NNPAS1 and NNPAS2). The data are not age-standardised.
