Up to date epidemiological evidence indicate, that sedentary behavior is an independent risk factor associated with cardiovascular and overall morbidity and mortality in adults. In PURE Poland baseline study, we also found time of sitting an independent risk factor of cardiovascular diseases (CVD). Many studies have consistently demonstrated a reduction in mortality in CVD associated with higher levels of aerobic fitness. In spite of these facts Polish national physical activity guidelines don’t specifically emphasize health risks related to nonexercise behavior, they usually address the need to improve physical activity in general.


The aim of the study was to investigate if time of sitting in baseline study can be treated as a predictor of CVD events in 6-years observation in PURE Poland study.


Poland is one of the 21 countries enrolled in global Prospective Urban and Rural Epidemiology Study (PURE). Study population consists of 1401 participants aged between 30 and 85 years, who were examined with the use of International Questionnaire of  Physical  Activity (IPAQ) – long form.  IPAQ includes physical activity questions related to different types of physical activity and time spent sitting. Participants with history of cardiovascular diseases in baseline were excluded from the analysis. Recorded CVD events included myocardial infarction, stroke, heart failure and angina (symptomatic coronary disease). The occurrence of CVD events was observed for 6 years after baseline. To assess the association between time of sitting and CVD events Wilcoxon rank sum test was chosen.

There was no statistically significant association between weekly total time of sitting and total CVD events (p=0,079).  Following the p-value given in Table 1, it can be seen that the association between sitting and HF is nearly on the border of statistical significance (p=0,059).


There is no obvious association between time of sitting and CVD events in 6-years observation.  In some of CVD events such as HF results are on the border of statistical significance and further observation is required.
