Introduction and objective: In Poland, there are only a few studies that refer to the whole society’s participation in sport and recreation and that are based an the international questionnaire thus allowing for comparative analysis with other European reports. The aim of the study was to determine the association between leisure physical activity and socio-demographic variables. Methods: A survey based on CAPI was carried out in Poland from October to November 2012. A random sample of Polish adults (N=1,633) was interviewed using the IPAQ-long form. The data were analyzed using standard statistical procedures. Results: More than 21% of Polish subjects did not undertake any physical activity in their leisure time. Of those who were physically active, over 70% engaged in vigorous physical activity; only one in four respondents performed moderate physical activity or walking. The average leisure physical activity of the Poles was 1,916.9 ± 2,621 MET-min/week. A comparison of the current results and European research findings demonstrated that the median physical activity for the Polish population (MET-min/week) was similar to the median values for Czech subjects and Norwegian males and nearly three times higher than Croats. Conclusions: Insufficient participation in the conscious process of caring for one’s health is a common occurrence among adults living in the EU. In order to encourage the Polish population’s participation in physical activities, it is necessary to raise their awareness of the need of well-balanced, regular exercise. Furthermore, this study suggests that caution is warranted before using the CAPI technique to provide the IPAQ-long form survey.
