Most of their waking time were spent sitting/lying (9.98 ± 1.71 hours/day; 58.4%) compared to standing (5.31 ± 1.61 hours/day; 31.1%) and stepping (1.79 ± 0.59 hours/day; 10.5%).

The rationale for recommendation of physical activity in cancer survivors relates to enhance
behavioural changes linked with minimising lifestyle risk factors for cancer recurrence. This study
aims to measure objectively measured physical activity and its association with quality of life among
breast cancer survivors. A cross-sectional study involving 96 breast cancer survivors was carried out
in two main government referral hospitals in the East Coast of Peninsular Malaysia. Participants wore
an ActivPAL3TM monitor for seven consecutive days on the midpoint of the anterior aspect of the
right thigh. The validated European Organization for Research and Treatment of Cancer Quality of
Life Questionnaires (EORTC QLQ – C30) and Breast Cancer Supplementary Measure (QLQ-BR23)
were used to measure quality of life of breast cancer patients. A total of 84 breast cancer survivors
provided valid data for sedentary behaviour analysis. The mean age of breast cancer survivors were
52.7 ± 7.7 years and BMI were 27.8 ± 4.9 kg/m². The total waking hours of breast cancer survivors
were 17.08 ± 1.09 hours/day and sleeping hours were 5.88 ± 1.15 hours/day. Most of their waking
time were spent sitting/lying (9.98 ± 1.71 hours/day; 58.4%) compared to standing (5.31 ± 1.61
hours/day; 31.1%) and stepping (1.79 ± 0.59 hours/day; 10.5%). The total steps among survivors were
7374 ± 2588 steps/day. In multiple linear regression, stepping (β= 0.083, p=0.002) was positively
associated with functioning score of EORTC QLQ-C30. Higher symptoms score that indicates more
severe symptoms was significantly associated with higher duration spent on sitting/lying (β= 0.029,
p=0.001). An increased number of longer sedentary bouts (≥ 30 minutes per sedentary bouts)
significantly increases the functioning score of QLQ-BR23 (β= 1.505, p=0.005). Standing, sedentary
breaks, and daily step counts were not associated with quality of life. In conclusion, breast cancer
survivors spent most of their waking hours doing sedentary activities. Strategies to displace sedentary
behaviour with stepping or standing and maintaining the sedentary bouts might be beneficial in
increasing survivorship and preventing cancer recurrence. |
