2.7. International Physical Activity Questionnaire Short Form (IPAQ-SF)

The IPAQ-SF was used to obtain internationally comparable data on health-related physical activity. It is a 9-item scale, assessing the amount of minutes spent on vigorous and moderate intense activity and walking during the last 7 days. In addition, the amount of minutes spent sitting on weekdays during the past 7 days is assessed. Data from the IPAQ-SF are summed within each item (i.e., vigorous intensity, moderate intensity and walking) to estimate the total amount of time spent engaged in physical activity per week [14].
