Long Term Effects of a Social Capital-Based Exercise Adherence Intervention for Breast Cancer Survivors With Moderate Fatigue: A Randomized Controlled Trial.

OBJECTIVES: This study reports on the long-term effects of the Better Life After Cancer: Energy, Strength, and Support (BLESS) program, a 12-week social capital-based exercise adherence program for breast cancer survivors (BCS), implemented using a randomized controlled trial design. The study investigated outcomes related to cancer-related fatigue (CRF), quality of life (QOL), physical activity, depression, anxiety, sleep quality, and social capital. METHODS: Participants who had moderate or greater CRF were randomly assigned to the intervention (n = 24), consisting of supervised and home-based exercise, or the control (n = 26), who received exercise leaflets. Generalized estimating equations models were fitted for the outcome variables. The assessment points were baseline (M1), immediately after completing the intervention at 12 weeks (M2), 1 month (M3), and 6 months post-intervention (M4). RESULTS: A significant reduction in the total CRF score was found for both groups. We observed a significant time by group effect at M2, indicating a reduction of behavioral/severity CRF scores and a higher increase of physical activity. Also, there was an increase in the QOL score of both groups at M2, M3, and M4, compared to M1. Both groups had reduced anxiety at M3 and M4 compared to M1. The time by group effect for depression, sleep quality and social capital was not statistically significant. CONCLUSION: This 12-week exercise adherence program improved behavioral/severity CRF and physical activity post-intervention. Both the experimental group and control group showed significant improvements in CRF, QOL, and anxiety domains compared to the baseline, which extended to 6 months post-intervention.

Pre-post analysis of a social capital-based exercise adherence intervention for breast cancer survivors with moderate fatigue: a randomized controlled trial.

PURPOSE: This study assessed the effectiveness of the Better Life After Cancer: Energy, Strength, and Support (BLESS) program, a 12-week social capital-based exercise adherence program for breast cancer survivors (BCS), regarding cancer-related fatigue (CRF), quality of life (QOL), physical activity, and psychosocial characteristics. METHODS: Forty-eight BCS with moderate or high (≥ 4) CRF participated in this randomized control trial (intervention group n = 23, control group n = 25). The intervention group participated in small group sessions to activate social capital while targeting CRF in supervised physical exercises supplemented by home-based physical exercises. The control group was only given written information on exercise. A questionnaire was used to assess CRF, QOL, physical activity, depression, anxiety, sleep quality, and social capital. RESULTS: The majority of participants had undergone surgery less than 2 years ago. After participating in BLESS, the CRF behavioral/severity domain significantly decreased (t = 2.642, p = 0.011) and physical activity significantly increased (t = - 2.049, p = 0.046) in the intervention group, in comparison with the control group; there were no significant post-intervention differences in the control group. Both groups showed improvements in sleep quality, depression, anxiety, and QOL. CONCLUSION: The BLESS program decreased behavioral/severity in the CRF and increased physical activity after 12 weeks among BCS. Future research needs to evaluate whether the promising results on physical activity and behavioral fatigue observed in the short term will persist over time. Also, longer-term effects should be examined.

Development of an exercise adherence program for breast cancer survivors with cancer-related fatigue-an intervention mapping approach.

PURPOSE: Cancer-related fatigue (CRF) is the most common and distressing symptom in breast cancer survivors (BCS), with severe impact on quality of life. CRF can be reduced through exercise, but conversely, is also a barrier to exercising. The aim of this article was to apply the intervention mapping protocol (IMP) to develop an exercise adherence intervention for BCS with CRF. METHOD: The program was developed using the IMP, which consists of six steps. Based on the data from focus group interviews and literature review, we produced a logic model of change. RESULTS: Two performance objectives (survivors adopt and maintain exercise and survivors cope with fatigue) and 17 change objectives were generated. Also, we designed theory-based methods of change, and strategies for practical application. A structured program plan that includes intervention content and methods, ranges, and program data was proposed. Finally, an implementation and evaluation plan was developed. CONCLUSION: The IMP provided a useful framework to systematically plan an exercise adherence program. This study resulted in a theory and practice-based exercise adherence program, based on behavioral change theories, and practice-based knowledge that fits the needs of BCS with CRF.

Role of social determinants and lifestyle on women's metabolic risk during the perimenopausal transition: results from a cohort study.

OBJECTIVE: Social determinants have been understudied in relation to metabolic risk and menopause; this study aimed to identify metabolic risk factors during menopausal transition, changes in lifestyle, and other social determinants. METHODS: The Korean Genetic Epidemiologic Survey Community cohort data available for baseline, 2-year, and 4-year follow-up time points were analyzed. Healthy women ages 45 to 55 years, not taking hormonal therapy, were selected; 1,228 were analyzed. Menopausal transition was categorized as premenopausal, perimenopausal, and postmenopausal. Lifestyle patterns consisted of alcohol consumption, exercise, ever smoking, indirect smoking, and eating breakfast. Generalized estimating equations were used for analysis. RESULTS: During the period of study, roughly 30% had become postmenopausal and metabolic syndrome was found in 11.5% to 14.4%. Controlling for other variables, lower income levels showed more than 2 times greater risk for metabolic syndrome in postmenopausal women and those who continued to menstruate. Body mass index was a consistent factor of metabolic risk, which was more pronounced when analyzed by menopausal status, especially in obese menstruating women (odds ratio 30.72, P < 0.0001). Among women who experienced menopause during the observed time frame, less education and sedentary lifestyle were also significant factors in metabolic risk differences, showing 1.7 times and 1.59 times greater risk, respectively. Such differences in education, income, and sedentary lifestyle as significant risk factors in subgroups according to menstrual status change, may suggest vulnerable points in the transition. CONCLUSIONS: Implications include the need for stronger emphasis on weight control before midlife and experiencing menopause, promoting exercise across the menopausal transition, and supportive policy measures for economically disadvantaged women.
