Physical activity

1. Key messages

Less than one third (30%) of the adult population (18 years and older) meets the WHO recommendations of doing at least 150 minutes of moderate-intensity aerobic physical activity throughout the week. More men (36%) comply than women (25%). Residents of Flanders (37%) and people with tertiary education (38%) were more likely to meet the recommendations.

Among children aged 11 to 18 years, one boy out of five (20%) and one girl out of eight (13%), meet the WHO recommendations of performing at least 60 minutes of moderate- to vigorous-intensity physical activity per day.

2. Background

Lack of physical activity is one of the leading risk factors in terms of both morbidity and mortality for a series of chronic conditions, including cardiovascular diseases, cancer, and diabetes. Moreover, regular physical activity, when reaching a certain threshold, can have significant benefits for health. The World Health Organization (WHO) [1] recommends that adults aged 18-64 perform at least 150 minutes of moderate-intensity physical activity throughout the week. They further recommend that children and teenagers aged 5-17 perform at least 60 minutes of moderate- to vigorous-intensity physical activity per day.

To date there is no consensus on the method for estimating levels of physical activity based on self-reported surveys: the use of different instruments and of different cut-off points for classifying the levels of activity make it very difficult to compare results within and between countries. In the Belgian Health Interview Survey (HIS), in waves 2001 to 2013, physical activity was measured with the short version of the International Physical Activity Questionnaire (IPAQ). Since 2018, the EHIS-PAQ questionnaire is used as recommended by the European Health Interview Survey (EHIS) whereby time trend analysis is no longer possible, but international comparability is enhanced.

In this report, we evaluate physical activity among adults based on the share of adults meeting the WHO recommendations to do at least 150 minutes of at least moderate-intensity aerobic physical activity throughout the week, based on the self-reported data from the Belgian Health Interview Survey (HIS).

Physical activity among adolescents is evaluated based on the share of adolescents aged 11-18 who meet the WHO recommendations to perform at least 60 minutes of moderate- to vigorous-intensity physical activity per day, based on self-reported data from the Health Behavior in School-aged Children (HBSC) survey.

3. Physical activity in adults

Situation in 2018

Belgium

In Belgium in 2018, 30% of the population aged 18 years and over did at least 150 minutes of at least moderate aerobic physical activity per week. More men (36%) than women (25%) met the recommendations, and this at all ages. The prevalence was the highest in the youngest age group (47%) and the lowest in the highest age group (12%).

Regional differences

More people were meeting the physical activity recommendations in Flanders (43% in men and 34% in women) than in Brussels (29% and 18%, respectively) and Wallonia (27% and 15%, respectively).

Socio-economic disparities

After age standardization, people with tertiary education were more likely to meet the recommendations (38%) than people with an upper secondary education (26%), a lower secondary education (22%), and primary education (12%).

4. Physical activity in adolescents

Situation in 2018

Belgium

In Belgium in 2018, more boys (20%) than girls (13%) met the WHO recommendations to perform at least 60 minutes of moderate- to vigorous-intensity physical activity per day. Young adolescents aged 11-12 years old were more likely to be sufficiently physically active than older adolescents.

Regional differences

More adolescents in the Flemish Community (21% of boys and 14% of girls) met the WHO recommendations than in the French Community (18% of boys and 11% of girls).

Trends

In the Flemish Community, the proportion of boys meeting the WHO recommendations increased between 2014 and 2018, while in the French Community, it decreased. These opposite evolutions led to a stable Belgian average.

In the Flemish Community, the proportion of girls meeting the WHO recommendations increased between 2014 and 2018, while in the French Community, it remained stable. Both evolutions combined led to an increasing Belgian average.

Definitions

Age-adjusted prevalence
Since lifestyle factors are strongly influenced by age, comparisons among regions and educational levels need to be standardized by age to have a similar age structure. 
EHIS-PAQ questionnaire 
The EHIS-PAQ is a domain-specific physical activity questionnaire compounded of eight questions. It takes into account physical activity related to work, going from and to places, and sport. The EHIS-PAQ was tested in different regions and cultural settings in Europe. It allows estimating the health-enhancing physical activity recommendation defined by the WHO.
Performing at least 150 minutes of at least moderate aerobic physical activity throughout the week
To calculate this indicator in the HIS, three questions were asked to the participants to assess the time they spend bicycling to get to and from places and the time they spend on sport leisure activities.
Performing at least 60 minutes of moderate- to vigorous-intensity physical activity per day
To calculate this indicator in the HBSC, the participants were asked how many days over the past week they had been physically active for a total of at least 60 minutes.
