ABSTRACT
BACKGROUND:
Low level of physical activity is a risk factor for new cardiac events in out-of-hospital cardiac arrest (OHCA) survivors. Physical activity can be assessed by self-reporting or objectively by accelerometery.AIM:
To investigate the agreement between self-reported and objectively assessed physical activity among OHCA survivorsHYPOTHESIS:
Self-reported levels of physical activity will show moderate agreement with objectively assessed levels of physical activity.METHOD:
Cross-sectional study including OHCA survivors in Sweden, Denmark, and the United Kingdom. Two questions about moderate and vigorous intensity physical activity during the last week were used as self-reports. Moderate and vigorous intensity physical activity were objectively assessed with accelerometers (ActiGraph GT3X-BT) worn upon the right hip for 7 consecutive days.RESULTS:
Forty-nine of 106 OHCA survivors answered the two questions for self-reporting and had 7 valid days of accelerometer assessment. More physically active days were registered by self-report compared with accelerometery for both moderate intensity (median 5 [37] vs. 3 [05] days; p < 0.001) and vigorous intensity (1 [03] vs. 0 [00] days; p < 0.001). Correlations between self-reported and accelerometer assessed physical activity were sufficient (moderate intensity rs = 0.336, p = 0.018; vigorous intensity rs = 0.375, p = 0.008), and agreements were fair and none to slight (moderate intensity k = 0.269, p = 0.001; vigorous intensity k = 0.148, p = 0.015). The categorization of self-reported versus objectively assessed physical activity showed that 26% versus 65% had a low level of physical activity.CONCLUSION:
OHCA survivors reported more physically active days compared with the results of the accelerometer assessment and correlated sufficiently and agreed fairly and none to slightly.Key words
