To evaluate the effects of cognitive behavioral therapy (CBT) and physical exercise (PE) for management of menopausal symptoms
Patients were randomized into four groups: wait list control, CBT alone, PE alone, or combined CBT and PE. The CBT interventions consisted of six weekly group sessions focusing on hot flashes and night sweats as well as other symptoms, with a booster session six weeks after completion of the program. The PE intervention was a 12-week individually tailored program of 2.5–3 weeks exercise of a type selected by the patient with assistance of a physiotherapist. Women were provided with heart rate monitors and instructed to achieve target hear rates. In weeks 4 and 8, women were contacted by phone for any need to adjust the program. Women in the combined group received both interventions concurrently. Study data were obtained at baseline, at 12 weeks, and six months later.
Randomized controlled trial
Overall effects showed group differences in hot flash symptoms (p < .001) and perceived burden of hot flashes and night sweats (p < .001), but not for the frequency of these symptoms. Effect sizes for study groups were 0.4 for CBT (p < 0.001), 0.31 for PE (p = .007), and 0.36 for the combined intervention (p = .001). Perceived problem rating was only seen in the CBT groups compared to controls at both 12 weeks and six months (p < 0.001). These effect sizes ranged from 0.39 to 0.56. Fifty eight percent of the CBT group were deemed noncompliant, as were 64% of the PE group and 70% of the combined intervention group. To be deemed compliant, subjects had to attend at least four of six CBT sessions and have a minimum of 25 PE training sessions with a specified level of caloric expenditure.
Both physical exercise and CBT interventions were associated with reduced hot flash symptoms, though not the frequency of those symptoms. CBT was helpful to reduce the degree to which patients perceived hot flashes as a problem. Adherence to these programs was low.
Findings suggest that both CBT and PE can be helpful in managing hot flash symptoms in women with breast cancer. CBT appears to be more helpful in assisting women to reduce the perceived level of problem created by the symptom. Participation in scheduled group sessions appeared to be difficult for subjects in this study, and many were currently employed, suggesting that this approach may not be practical for many patients. Alternative methods of delivery to achieve results that are practical for patients need to be explored.
