OBJECTIVE: The objective of this study was to ascertain whether wearable technology, coupled with action-planning was effective in increasing physical activity (PA) in colorectal and endometrial cancer survivors at cardiovascular risk.
METHODS: Sixty-eight survivors who had cardiovascular risk factors and were insufficiently active were randomized to intervention and control arms. Intervention participants were given a wearable tracker for 12-weeks, two group sessions, and a support phone-call. Participants in the control arm received print materials describing PA guidelines. Assessments at baseline and 12-weeks measured triaxial and uniaxial estimates of moderate-vigorous physical activity (MVPA), sedentary behavior, blood pressure and BMI.
RESULTS: The intervention group significantly increased MVPA by 45-minutes/week compared to a reduction of 21-minutes/week in the control group. Group by time interactions were significant for minutes of MVPA (F(1,126)=5.14, p =.025). For those with diastolic hypertension, there was a significant group by time interaction (F(1,66)=4.89, p =.031) with a net reduction of 9.89mmHg in the intervention group.
CONCLUSIONS: Significant improvements in MVPA were observed following the intervention. The results display promise for the use of pragmatic, low-intensity interventions using wearable technology.
