Breast cancer survivors are a unique cancer population in that they are having success in treatment but are experiencing the negative side effects that various treatments cause, whether it be soon or very long after treatment. As a result of advances in treatment, less and less breast cancer survivors are dying from of their disease. Instead, their mortality is caused by the other conditions that they become at risk for from the treatment effects. Weight gain is an example of one of these side effects that is seen in breast cancer survivors that places these individuals at risk for poor cardiovascular and metabolic health. The combination of benefits seen from engagement in physical activity and dietary behavior change could lend itself to an optimal approach to mitigate the detrimental side effects that we see, especially weight gain. The lifestyle weight management literature in breast cancer survivors has shown that physical activity can be performed safely and effectively, and the inclusion of diet aids in further improvements in weight management. With the increased knowledge and community support for breast cancer survivor programming, assessing the feasibility and preliminary efficacy of a community-based lifestyle weight management intervention will assist in addressing the lack of community access that currently exists for breast cancer survivors after their treatment. The purpose of this study is to determine the feasibility and preliminary efficacy of a community-based lifestyle weight management intervention in breast cancer survivors on select body composition, physical function, and quality of life outcomes during the first 3 months of the first wave of the Healthy New Albany Breast Cancer (HNABC) pilot trial. The 24-week, HNABC study is held at a community center and promotes lifestyle behavior changes through a group-mediated cognitive behavioral (GMCB) approach driven by Social Cognitive Theory, in hopes of producing meaningful results for feasibility and secondary outcomes. In the present study, 11 breast cancer survivors participated in the first wave of HNABC. The measures analyzed in this study were body composition done via dual-energy x-ray absorptiometry (DXA), physical function or mobility performance via the 400-meter walk test, and social cognitive outcomes via satisfaction with function and appearance and perceived competence with exercise and diet at the 3-month follow-up assessment. Results Effect size calculations and feasibility parameters were used to examine the potential effects that the intervention had on changes in body composition, physical function, and social cognitive outcomes at the 3-month follow-up. The effect sizes, using Cohen’s d, were calculated by taking the mean difference and dividing by the pooled standard deviation to determine the magnitude of differences observed for each outcome. Meaningful changes were observed in fat mass (d= -0.14), percent fat mass (d= -0.24), lean mass (d= -0.004), and physical function (d= -0.50), some of which reached clinical relevance. Self-reported outcomes also saw meaningful improvements, which attests to the beneficial ability of the GMCB methodology in increasing perceived competence and satisfaction levels. Conclusions Findings from the initial wave of the HNABC pilot trial provide evidence of the feasibility, safety, and preliminary efficacy of implementing a GMCB-based lifestyle weight management intervention among overweight or obese breast cancer survivors. Given the meaningful impact that successful weight management has on reducing risk for chronic diseases, these results highlight the utility of implementing a lifestyle weight management intervention in the community for breast cancer survivors in an effort to extend the reach and availability of care during breast cancer survivorship.
