Abstract

PURPOSE
This study aimed to analyze physical activity as measured by the International Physical Activity Questionnaire (IPAQ) and an actigraph in breast cancer survivors, as well as to identify their intention to participate in a physical activity program.
METHODS
Breast cancer patients who had been diagnosed for more than six months (N=135) at a university hospital participated from June 2012 to May 2013. Physical activity was measured using the Korean version of the IPAQ-Short Form and Actigraph GT3X plus an accelerator for seven consecutive days. Data analyses were conducted using the SPSS WIN 19.0 program.
RESULTS
Mean total physical activity was 2298.21 metabolic equivalent task (MET)-min/week as assessed by IPAQ and 150,140.57 counts/day as measured by an actigraph. There were statistically significant correlations between moderate physical activity from IPAQ and light intensity of physical activity from the actigraph (r=.735, p<.001), vigorous physical activity from IPAQ and vigorous intensity of physical activity from the actigraph (r=.871, p<.001), total physical activity from IPAQ and light intensity of physical activity from the actigraph (r=.825, p<.001), respectively. Most (80.7%) cancer survivors reported a positive attitude toward physical activity and 57.8% expressed a willingness to participate in a physical activity program. More than half (60%) of the subjects preferred walking, 80.6% preferred more than 30 minutes of exercise, and 57.1% wanted to engage in physical activity three times a week and preferred home-based activities. Perceived barriers included fatigue, lack of strength and pain.
CONCLUSION
It is necessary to consider intensity, personal preferences, and patient-perceived barriers when developing physical activity programs for breast cancer survivors.
