Associations between self-reported post-diagnosis physical activity changes, body weight changes, and psychosocial well-being in breast cancer survivors

Abstract Objectives This study aims to evaluate the adherence to a dietary, physical activity, and body weight intervention using the principles of Motivational Interviewing (MI) in female breast cancer survivors who participated in a trial for 4 months. Methods Premenopausal and postmenopausal female cancer survivors (n = 47) were randomized to the intervention group (IG, n = 22) that received the MI strategy, or the comparison group (CG, n = 25) that received nutritional counseling. Adherence to the program was evaluated based on compliance with dietary and physical activity goals, changes in body weight and changes in serum levels of α-carotene and β-carotene. We applied two non-consecutive 24-hour recalls to estimate dietary intake, and used a pedometer to measure number of steps. Blood samples were taken at time 0 (basal) and at 4 months of the study, and the serum concentrations of α-carotene and β-carotene were evaluated by high-performance liquid chromatography. Results Among participants in the IG, percentages of compliance with goals for fruit and vegetable intakes were 93% and 90% respectively. The consumption of red, green and yellow vegetables increased (135.3 to 148.6 g/day, 192.1 to 227.7 g/day and 49.1 to 58.9 g/day, respectively) in the IG. There were no differences in fiber or total sugar intakes between groups. Women in the IG significantly increased their serum β-carotene levels (median 10.7 to 21.2 μg/dL) compared to the CG (median 13.1 to 19.9 μg/dL) (P < 0.05). The number of steps increased in the IG compared to the CG (1865 vs. 189, P < 0.05), although participants in the two groups continued to be classified as sedentary (physical activity level <1 at 0 and 4 months). Women in the IG lost 1.75 kg of body weight compared to 0.70 kg in the CG (P = 0.08). Conclusions Findings indicate that adherence to the recommendation on fruit and vegetable intakes is relatively high and that adherence to the recommendation on fiber intake, sugar intake, body weight and physical activity should be promoted. The MI strategy is promising to motivate changes in lifestyle changes.

Steps Per Day

Maintaining adequate amounts of physical activity is a critical component of survivorship care for women with breast cancer. Increased physical activity is associated with increases in well-being, quality of life, and longevity, but women with cancer face unique, cancer-related factors that might affect physical activity. Consistent with the Competing Neurobehavioral Decision Systems model of decision making, we proposed to decrease delay discounting and increase physical activity by stimulating the executive function system via high-frequency repetitive transcranial magnetic stimulation (HF rTMS) of the left dorsolateral prefrontal cortex (LDLPFC). This randomized, sham-controlled, double-blinded trial examined the feasibility and potential efficacy of this approach to increase physical activity in breast cancer survivors. We hypothesized that active rTMS would significantly increase the mean number of steps per day and decrease delay discounting. Participants (n = 30) were primarily middle-aged (M = 53.7, SD = 7.9) and white with a mean BMI and body mass indices below 40. Indicators of feasibility and limited efficacy testing were positive. Although repeated-measures ANOVA revealed no significant changes in delay discounting, generalized estimating equations (GEE) found that participants in the active condition increased their mean daily steps by 400 steps per day, while those in the sham condition decreased this by nearly 600 steps per day. These findings indicate that the continued investigation of HF rTMS for increasing physical activity among women with breast cancer is justified.
