Conclusions : The available literature suggests that African American breast cancer survivors adhere to interventions of various modalities and are capable of making modest to significant changes .
Background : African American breast cancer survivors have a higher incidence of estrogen receptor negative and basal-like ( e.g. , triple negative ) tumors , placing them at greater risk for poorer survival when compared to women of other racial and ethnic groups .
While access to equitable care , late disease stage at diagnosis , tumor biology , and sociodemographic characteristics contribute to health disparities , poor lifestyle characteristics ( i.e. , inactivity , obesity , and poor diet ) contribute equally to these disparities .
Lifestyle interventions hold promise in shielding African American survivors from second cancers , comorbidities , and premature mortality , but they are often underrepresented in studies promoting positive behaviors .
This review examined the available literature to document health behaviors and lifestyle intervention ( i.e. , obesity , physical activity , and sedentary behavior ) studies in African American breast cancer survivors .
Safety and Efficacy of Weight Training in Recent Breast Cancer Survivors to Alter Body Composition, Insulin, and Insulin-Like Growth Factor Axis Proteins
Background : This r and omized controlled trial assessed the safety and effects of twice-weekly weight training among recent breast cancer survivors . Outcomes included body size and biomarkers hypothesized to link exercise and breast cancer risk . Methods : A convenience sample of 85 recent survivors was r and omized into immediate and delayed treatment groups . The immediate group trained from months 0 to 12 ; the delayed treatment group served as a no exercise parallel comparison group from months 0 to 6 and trained from months 7 to 12 . Measures at baseline , 6 and 12 months included body weight , height , body fat , lean mass , body fat % , and waist circumference , as well as fasting glucose , insulin , insulin resistance , insulin-like growth factor-I ( IGF-I ) , IGF-II , and IGF-binding protein-1 , IGFBP-2 , and IGFBP-3 . Injury reporting was st and ardized . Results : The intervention result ed in significant increases in lean mass ( 0.88 versus 0.02 kg , P < 0.01 ) , as well as significant decreases in body fat % ( −1.15 % versus 0.23 % , P = 0.03 ) and IGF-II ( −6.23 versus 28.28 ng/mL , P = 0.02 ) comparing immediate with delayed treatment from baseline to 6 months . Within-person changes experienced by delayed treatment group participants during training versus no training were similar . Only one participant experienced a study related injury that prevented continued participation . Conclusion : Twice-weekly weight training is a safe exercise program for recent breast cancer survivors that may result in increased muscle mass , as well as decreased body fat % and IGF-II . The implication s of these results on cancer recurrence or survival may become more evident with longer exercise intervention trials among breast cancer survivors
