Breast cancer survivors' satisfying marriages predict better psychological and physical health: A longitudinal comparison of satisfied, dissatisfied, and unmarried women. Psychooncology 2021; 30:699-707. [PMID: 33340188 DOI: 10.1002/pon.5615] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 12/15/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Breast cancer survivors who experience psychological and physical symptoms after treatment have an increased risk for comorbid disease development, reduced quality of life, and premature mortality. Identifying factors that reduce or exacerbate their symptoms may enhance their long-term health and physical functioning. This study examined how survivors' marital status and marital satisfaction-key health determinants-impacted their psychological and physical health trajectories to understand when, and for whom, marriage offers health benefits. METHODS Breast cancer survivors (n = 209, stages 0-IIIC) completed a baseline visit before treatment and two follow-up visits 6 and 18 months after treatment ended. Women completed questionnaires assessing their marital status and satisfaction when applicable, as well as their psychological (depressive symptoms, stress) and physical (fatigue, pain) health at each visit. RESULTS Married women-both those in satisfying and dissatisfying marriages-experienced improvements in their depressive symptoms, stress, and fatigue from pretreatment to 6- and 18-month posttreatment. Unmarried (i.e., single, divorced/separated, or widowed) women's depressive symptoms, stress, fatigue, and pain did not change over time, instead remaining elevated 6 and 18 months after treatment ended. Women in satisfying marriages also had fewer psychological and physical symptoms after treatment than those who were unmarried or in dissatisfying marriages. CONCLUSIONS Although marriage was associated with improved psychological and physical health, the gains were most notable when survivors' marriages were satisfying. Thus, the quality of survivors' marriages, rather than the marriage itself, provided the most benefits to their psychological and physical health.

Abstract
Purpose The aim of this review was to summarize the current literature for the effectiveness of activity and nutritional based interventions on health-related quality of life (HRQoL) in older adults living with and beyond cancer (LWBC). Methods We conducted systematic structured searches of CINAHL, Embase, Medline, Cochrane CENTRAL databases, and bibliographic review. Two independent researchers selected against inclusion criteria: (1) lifestyle nutrition and/or activity intervention for people with any cancer diagnosis, (2) measured HRQoL, (3) all participants over 60 years of age and (4) randomized controlled trials. Results Searches identified 5179 titles; 114 articles had full text review, with 14 studies (participant n = 1660) included. Three had nutrition and activity components, one, nutrition only and ten, activity only. Duration ranged from 7 days to 1 year. Interventions varied from intensive daily prehabilitation to home-based gardening interventions. Studies investigated various HRQoL outcomes including fatigue, general and cancer-specific quality of life (QoL), distress, depression, global side-effect burden and physical functioning. Eight studies reported significant intervention improvements in one or more QoL measure. Seven studies reported using a psychosocial/theoretical framework. There is a gap in tailored nutrition advice. Conclusions Among the few studies that targeted older adults with cancer, most were activity-based programmes with half reporting improvements in QoL. Future research should focus on or include tailored nutrition components and consider appropriate behaviour change techniques to maximize potential QoL improvement. Implications for Cancer Survivors More research is needed to address the research gap regarding older adults as current recommendations are derived from younger populations.

Support Care Cancer 2020; 28:4005-4017. [PMID: 32296982 DOI: 10.1007/s00520-020-05453-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 04/01/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials. METHODS We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery. RESULTS Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology. CONCLUSIONS This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

Abstract
Stressful life events such as losing a spouse can enhance inflammation. Responses to loss may depend, in part, on individual differences in attachment anxiety and avoidance. An individual's attachment orientation (i.e., an individual's levels of attachment anxiety and avoidance) reflects how an individual relates to others-- specifically, whether they feel their trusted others will reliably be there for them, and whether they feel comfortable opening up to and depending on their relationship partners. This study investigated the association between attachment orientations and poor loss adjustment in recently bereaved individuals (N = 100). Poor loss adjustment was operationalized as greater levels of inflammation and grief symptoms, as well as poorer self-reported mental and physical health. Attachment anxiety was associated with increased stimulated monocyte IL-6 and CCL4 production, but not TNFα. Likewise, attachment anxiety was associated with greater grief symptoms as well as poorer mental and physical health. In contrast, attachment avoidance was not associated with inflammation; it was, however, associated with less grief symptoms as well as better self-reported mental and physical health. Our findings provide evidence that attachment orientations may be associated with loss adjustment and adverse health outcomes following the recent loss of a spouse.

Abstract
BACKGROUND Nutrition is important for prostate cancer (PC) survivorship care to help achieve a healthy weight, reduce treatment side effects and reduce the risk of developing other chronic diseases. We aimed to advance the understanding of the nutritional needs of men with PC and services that could be potentially implemented to address them. METHODS We conducted a needs assessment of nutrition services for men with PC drawing on four perspectives; 1) patient evaluation of a nutrition education session in British Columbia (BC), 2) survey of BC health professionals, 3) an environmental scan of existing nutrition services across Canada and 4) a scoping literature review. RESULTS Patients expressed a need for more nutrition information and a desire for additional nutrition services. More than 60% of health professionals believed there is a need for more nutrition services for men with PC, and reported the focus should be on weight management or management of PC progression. The environmental scan revealed few existing services for men with PC across Canada, most were inclusive of multiple cancers and not tailored for men with PC. Eighteen completed studies were identified in the scoping literature review. The majority provided combined diet and exercise programs with various formats of delivery such as individual, group and home-based. Overall, 78% of studies reported improvements in one or more of the following measures: dietary intake/ diet quality, body composition, self-efficacy, quality of life, fatigue, practicing health behavior goals and physical function/ exercise. Four studies assessed feasibility, adherence or satisfaction with all reporting positive findings. CONCLUSION Despite the high prevalence of PC in Canada, and the perceived need for more support by patients and health professionals, there are limited nutrition services for men with PC. Evidence from the literature suggests nutrition services are effective and well-accepted by men with PC. Our findings define a need for standardized nutrition services for men with PC that assess and meet long term nutritional needs. Our findings also provide insight into the type and delivery of nutrition services that may help close the gap in care for men with PC.

Abstract
BACKGROUND International dietary recommendations include guidance on healthy eating and weight management for people who have survived cancer; however dietary interventions are not provided routinely for people living beyond cancer. OBJECTIVES To assess the effects of dietary interventions for adult cancer survivors on morbidity and mortality, changes in dietary behaviour, body composition, health-related quality of life, and clinical measurements. SEARCH METHODS We ran searches on 18 September 2019 and searched the Cochrane Central Register of Controlled trials (CENTRAL), in the Cochrane Library; MEDLINE via Ovid; Embase via Ovid; the Allied and Complementary Medicine Database (AMED); the Cumulative Index to Nursing and Allied Health Literature (CINAHL); and the Database of Abstracts of Reviews of Effects (DARE). We searched other resources including reference lists of retrieved articles, other reviews on the topic, the International Trials Registry for ongoing trials, metaRegister, Physicians Data Query, and appropriate websites for ongoing trials. We searched conference abstracts and WorldCat for dissertations. SELECTION CRITERIA We included randomised controlled trials (RCTs) that recruited people following a cancer diagnosis. The intervention was any dietary advice provided by any method including group sessions, telephone instruction, written materials, or a web-based approach. We included comparisons that could be usual care or written information, and outcomes measured included overall survival, morbidities, secondary malignancies, dietary changes, anthropometry, quality of life (QoL), and biochemistry. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. Two people independently assessed titles and full-text articles, extracted data, and assessed risk of bias. For analysis, we used a random-effects statistical model for all meta-analyses, and the GRADE approach to rate the certainty of evidence, considering limitations, indirectness, inconsistencies, imprecision, and bias. MAIN RESULTS We included 25 RCTs involving 7259 participants including 977 (13.5%) men and 6282 (86.5%) women. Mean age reported ranged from 52.6 to 71 years, and range of age of included participants was 23 to 85 years. The trials reported 27 comparisons and included participants who had survived breast cancer (17 trials), colorectal cancer (2 trials), gynaecological cancer (1 trial), and cancer at mixed sites (5 trials). For overall survival, dietary intervention and control groups showed little or no difference in risk of mortality (hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.77 to 1.23; 1 study; 3107 participants; low-certainty evidence). For secondary malignancies, dietary interventions versus control trials reported little or no difference (risk ratio (RR) 0.99, 95% CI 0.84 to 1.15; 1 study; 3107 participants; low-certainty evidence). Co-morbidities were not measured in any included trials. Subsequent outcomes reported after 12 months found that dietary interventions versus control probably make little or no difference in energy intake at 12 months (mean difference (MD) -59.13 kcal, 95% CI -159.05 to 37.79; 5 studies; 3283 participants; moderate-certainty evidence). Dietary interventions versus control probably led to slight increases in fruit and vegetable servings (MD 0.41 servings, 95% CI 0.10 to 0.71; 5 studies; 834 participants; moderate-certainty evidence); mixed results for fibre intake overall (MD 5.12 g, 95% CI 0.66 to 10.9; 2 studies; 3127 participants; very low-certainty evidence); and likely improvement in Diet Quality Index (MD 3.46, 95% CI 1.54 to 5.38; 747 participants; moderate-certainty evidence). For anthropometry, dietary intervention versus control probably led to a slightly decreased body mass index (BMI) (MD -0.79 kg/m², 95% CI -1.50 to -0.07; 4 studies; 777 participants; moderate-certainty evidence). Dietary interventions versus control probably had little or no effect on waist-to-hip ratio (MD -0.01, 95% CI -0.04 to 0.02; 2 studies; 106 participants; low-certainty evidence). For QoL, there were mixed results; several different quality assessment tools were used and evidence was of low to very low-certainty. No adverse events were reported in any of the included studies. AUTHORS' CONCLUSIONS Evidence demonstrated little effects of dietary interventions on overall mortality and secondary cancers. For comorbidities, no evidence was identified. For nutritional outcomes, there was probably little or no effect on energy intake, although probably a slight increase in fruit and vegetable intake and Diet Quality Index. Results were mixed for fibre. For anthropometry, there was probably a slight decrease in body mass index (BMI) but probably little or no effect on waist-to-hip ratio. For QoL, results were highly varied. Additional high-quality research is needed to examine the effects of dietary interventions for different cancer sites, and to evaluate important outcomes including comorbidities and body composition. Evidence on new technologies used to deliver dietary interventions was limited.

Abstract
BACKGROUND Physically active cancer survivors have a reduced risk of cancer recurrence and mortality. Given the health advantages of active lifestyles in cancer survivorship, as well as the barriers preventing physical activity (e.g., geography, time) there is a need to develop and evaluate effective physical activity interventions that employ distance-based (i.e., non face-to-face) approaches. The primary objective of this study was to provide a systematic review and meta-analysis of present-day (2013-2018) distance-based physical activity behaviour change interventions for cancer survivors. METHODS PubMed and Embase databases were searched from November 2012 up to June 2018. Studies were included that met the following criteria: (1) written in English, (2) included adult cancer survivors (either undergoing or completed treatment), (3) was a controlled intervention study, and (4) the intervention was distance-based (delivered via distance) with no more than one face-to-face contact. Review Manager 5 (RevMan 5) software was used to perform a meta-analysis on all randomized controlled trials (RCTs) that presented self-reported or objectively measured physical activity post-intervention means and standard deviations. Risk of bias for each study was assessed using The Cochrane Risk of Bias Tool. RESULTS We included 29 RCTs. Across the 29 studies, the total number of participants in these studies was 5218. Median sample size was 95 and ranged from 19 to 463. Thirteen (45%) studies focused on breast cancer survivors and median months since diagnosis was 24 (range 6-79). Moderate-to-vigorous intensity physical activity data from 24 RCTs were included in the meta-analysis and indicated an overall small effect (standardized mean difference) of 0.21 (95% CI 0.11-0.32) favoring the interventions. CONCLUSIONS Intervention effects on physical activity were small. Drawing conclusions from these trials remains challenging given major limitations of these trials included poor methodological design, small sample sizes, lack of statistical power, homogeneous samples (e.g., caucasian, young, well-educated), and poor measures of physical activity (e.g., self-report). Relying on the present landscape of distance-based programs aiming to facilitate physical activity among cancer survivors may not be prudent.

Abstract
BACKGROUND The aim of this study was to examine predictors of health behaviors over time and the link between health behaviors and survival after a diagnosis of advanced cancer. METHODS Patients with a diagnosis of advanced cancer were administered a battery of questionnaires measuring optimism, depressive symptoms, physical activity, intake of fruits and vegetables, and alcohol and tobacco use over an 18-month period. Analyses included generalized linear mixed models and Cox regression survival analyses. RESULTS Of the 334 patients enrolled in the study, the mean age at cancer diagnosis was 62 years; the majority were male (62.3%) and white (91%). Twenty percent of the patients reported using alcohol, 19% reported using tobacco, 19% reported eating fewer fruits and vegetables than recommended by the Centers for Disease Control and Prevention and 28% reported physical inactivity after the diagnosis of advanced cancer. Clinical levels of depressive symptoms were associated with lower intake of fruits and vegetables (t = 2.67, P = .007) and physical inactivity (t = 2.11, P = .035). Dispositional optimism was positively associated with physical activity (t = -2.16, P = .031) and a lower frequency of tobacco use (Z = -2.42, P = .015). Multivariate analyses revealed that after adjusting for demographic variables (age and sex), depressive symptoms, and disease-specific factors (diagnosis, tumor size, cirrhosis, vascular invasion, and number of lesions), alcohol use (χ2 = 4.1186, P = .042) and physical inactivity (χ2 = 5.6050, P = .018) were linked to an poorer survival. CONCLUSIONS Greater dissemination and implementation of effective interventions to reduce alcohol use and increase physical activity in cancer patients are recommended.

Abstract
PURPOSE Men who are survivors of prostate cancer report a variety of psychological and physical factors contributing to a lower quality of life, and physical activity can assist to mitigate these issues. This review aims to provide a summary of physical activity behaviour change trials targeting prostate cancer survivors, assess the feasibility of these interventions and, if possible, identify intervention and study characteristics associated with significant intervention effects. METHOD Four databases (PubMed, CINAHL, PsycINFO and EMBASE) were systematically searched for randomised controlled trials containing at least one behavioural outcome relating to physical activity published up until July 2016. Forward and backwards, hand, key author citation searching and known research were also considered. RESULTS From a total of 13, 828 titles, the search resulted in 12 studies (6 prostate cancer only and 6 mixed cancer interventions), eight of which found positive results most often related immediately to post-intervention aerobic activity. Factors relating to efficacy were not conclusive due to the heterogeneity of studies and lack of cancer-specific data in mixed cancer trials. Future research focusing on intervention reach, maintenance of intervention effects and resistance training outcomes is needed. CONCLUSION There is preliminary evidence to suggest that a variety of physical activity behaviour change interventions targeting men with a history of prostate cancer can be efficacious, at least in the short term. Experimental studies are required to identify key intervention features. IMPLICATIONS FOR CANCER SURVIVORS Physical activity interventions can assist prostate cancer survivors in relation to short-term lifestyle change, though more evidence is required to improve the clarity of factors related to efficacy.

Abstract
Multiple health behavior change (MHBC) interventions have great potential for enhancing health and well-being following cancer diagnosis and treatment. However, the characteristics and effects of MHBC interventions remain elusive for cancer survivors. The main purpose of this study was to evaluate the effectiveness of MHBC interventions on healthy eating and physical activity behaviors among cancer survivors. A secondary aim was to examine the effect of using a simultaneous and sequential design approach to MHBC (ie, changing both behaviors at the same time or one after the other). Randomized controlled trials reporting the impact of a MHBC intervention on both healthy eating and physical activity behaviors among cancer survivors were retrieved from MEDLINE, Cochrane Library, and PsycINFO. A total of 27 MHBC interventions were identified; most (92.6%) were designed to promote simultaneous change in both behaviors and assessed end-of-treatment effect among breast cancer survivors. MHBC interventions led by nurses or multidisciplinary teams showed the most compelling evidence for small to moderate improvement in both behaviors, with interventions that lasted ≥17 weeks more likely to improve both behaviors. This study identifies research priorities and provides preliminary evidence for clinical decision making and advancements in MHBC intervention design and delivery for clinical oncology.

Abstract
BACKGROUND A huge clinical research database on adjuvant cancer treatment has verified improvements in breast cancer outcomes such as recurrence and mortality rates. On the other hand, adjuvant and neoadjuvant therapy with chemotherapy and radiotherapy impacts on quality of life due to substantial short- and long-term side effects. A number of studies have evaluated the effect of exercise interventions on those side effects. This is an updated version of the original Cochrane review published in 2006. The original review identified some benefits of physical activity on physical fitness and the resulting capacity for performing activities of daily life. It also identified a lack of evidence for other outcomes, providing clear justification for an updated review. OBJECTIVES To assess the effect of aerobic or resistance exercise interventions during adjuvant treatment for breast cancer on treatment-related side effects such as physical deterioration, fatigue, diminished quality of life, depression, and cognitive dysfunction. SEARCH METHODS We carried out an updated search in the Cochrane Breast Cancer Group Specialised Register (30 March 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2015), MEDLINE (1966 to 30 March 2015), and EMBASE (1966 to 30 March 2015). We did not update the original searches in CINAHL (1982 to 2004), SPORTDiscus (1975 to 2004), PsycINFO (1872 to 2003), SIGLE (1880 to 2004), and ProQuest Digital Dissertations (1861 to 2004). We searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov for ongoing trials on 30 March 2015. We screened references in relevant reviews and published clinical trials. SELECTION CRITERIA We included randomised controlled trials that examined aerobic or resistance exercise or both in women undergoing adjuvant treatment for breast cancer. Published and unpublished trials were eligible. DATA COLLECTION AND ANALYSIS Two review authors independently performed data extraction, assessed trials, and graded the methodological quality using Cochrane's 'Risk of bias' tool. Any disagreements were resolved through discussion or by consulting the third review author. We entered data into Review Manager for analysis. For outcomes assessed with a variety of instruments, we used the standardised mean difference (SMD) as a summary statistic for meta-analysis; for those assessed with the same instrument, we used the mean difference (MD). MAIN RESULTS For this 2015 update we included a total of 32 studies with 2626 randomised women, 8 studies from the original search and 24 studies from the updated search. We found evidence that physical exercise during adjuvant treatment for breast cancer probably improves physical fitness (SMD 0.42, 95% confidence interval (CI) 0.25 to 0.59; 15 studies; 1310 women; moderate-quality evidence) and slightly reduces fatigue (SMD -0.28, 95% CI -0.41 to -0.16; 19 studies; 1698 women; moderate-quality evidence). Exercise may lead to little or no improvement in health-related quality of life (MD 1.10, 95% CI -5.28 to 7.48; 1 study; 68 women; low-quality evidence), a slight improvement in cancer site-specific quality of life (MD 4.24, 95% CI -1.81 to 10.29; 4 studies; 262 women; low-quality evidence), and an improvement in cognitive function (MD -11.55, 95% CI -22.06 to -1.05; 2 studies; 213 women; low-quality evidence). Exercise probably leads to little or no difference in cancer-specific quality of life (SMD 0.12, 95% CI 0.00 to 0.25; 12 studies; 1012 women; moderate-quality evidence) and little or no difference in depression (SMD -0.15, 95% CI -0.30 to 0.01; 5 studies; 674 women; moderate-quality evidence). Evidence for other outcomes ranged from low to moderate quality. Seven trials reported a very small number of adverse events. AUTHORS' CONCLUSIONS Exercise during adjuvant treatment for breast cancer can be regarded as a supportive self care intervention that probably results in less fatigue, improved physical fitness, and little or no difference in cancer-specific quality of life and depression. Exercise may also slightly improve cancer site-specific quality of life and cognitive function, while it may result in little or no difference in health-related quality of life. This review is based on trials with a considerable degree of clinical heterogeneity regarding adjuvant cancer treatments and exercise interventions. Due to the difficulty of blinding exercise trials, all included trials were at high risk for performance bias. Furthermore, the majority of trials were at high risk for detection bias, largely due to most outcomes being self reported.The findings of the updated review have enabled us to make a more precise conclusion that both aerobic and resistance exercise can be regarded as beneficial for individuals with adjuvant therapy-related side effects. Further research is required to determine the optimal type, intensity, and timing of an exercise intervention. Furthermore, long-term evaluation is required due to possible long-term side effects of adjuvant treatment.

Abstract
Increasingly effective adjuvant therapies mean that the prognosis for postmenopausal women with breast cancer has never been better. Weight problems are common among breast cancer patients and worsen due to the impact of diagnosis and treatment. Recent studies have linked excess weight with the risk of recurrence of breast cancer among premenopausal women. While general obesity (body mass index) does not appear to influence the already much improved prognosis for postmenopausal women, there is some evidence that limiting central obesity and improving insulin resistance may improve survival. The focus of attention for postmenopausal breast cancer survivors is also shifting to consider the mortality and morbidity from other weight-related cancers and noncancer causes, such as cardiovascular disease, making weight control a potentially important adjunct to endocrine therapy. This paper outlines the rationale and optimal design for effective weight management strategies among postmenopausal breast cancer patients receiving endocrine therapy.

Motivating parents of kids with asthma to quit smoking: the effect of the teachable moment and increasing intervention intensity using a longitudinal randomized trial design. Addiction 2016; 111:1646-55. [PMID: 27184343 PMCID: PMC5404816 DOI: 10.1111/add.13389] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Revised: 10/16/2015] [Accepted: 03/07/2016] [Indexed: 11/27/2022]
Abstract
AIMS We tested two aims: (1) the teachable moment (TM): whether second-hand smoke exposure (SHSe) feedback motivates cessation in parents of children with asthma versus parents of healthy children (HC); and (2) whether greater intervention intensity [enhanced-precaution adoption model (PAM)] produces greater cessation than a previously tested intervention (PAM). DESIGN AND INTERVENTIONS Aim 1: two home visits (asthma education or child wellness), and cessation induction using motivational interviewing and SHSe feedback. Aim 2: post-home-visits, parents with asthmatic children were randomized to PAM (n = 171; six asthma education calls) or enhanced-PAM (n = 170; six asthma education/smoking cessation calls + repeat SHSe feedback). SETTING Rhode Island, USA. PARTICIPANTS Parents of asthmatic (n = 341) or healthy (n = 219) children who did not have to want to quit smoking to enroll. MEASUREMENTS Measurements were given at baseline, 2, 4, 6 and 12 months. Abstinence was bioverified. Outcomes were 7-day and 30-day point prevalence abstinence (ppa) and SHSe (primary) and asthma morbidity (secondary). FINDINGS Aim 1: the TM was supported: parents of asthmatic children were more than twice as likely to achieve 30-day [odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.22-5.54] and 7-day ppa (OR = 2.26, 95% CI = 1.13-4.51) at 2 months (primary end-point) and have non-detectable levels of SHSe than HCs. Greater treatment intensity yielded stronger TM effects (OR = 3.60; 95% CI = 1.72-7.55). Aim 2: enhanced-PAM was more likely to achieve 30-day ppa at the primary end-point, 4 months (OR = 2.12, 95% CI 1.09-4.12) and improved asthma outcomes versus PAM. CONCLUSIONS Smoking cessation intervention (Motivational Interviewing plus biomarker feedback) appear to motivate smoking cessation more strongly among parents of asthmatic children than among parents of healthy children. Increased intervention intensity yields greater smoking cessation among parents of asthmatic children and better asthma outcomes.

Abstract
BACKGROUND To improve adherence to physical activity (PA), behavioural support in the form of behavioural change counselling may be necessary. However, limited evidence of the effectiveness of home-based PA combined with counselling in breast cancer patients exists. The aim of this current randomised controlled trial with a parallel group design was to evaluate the effectiveness of a home-based PA intervention on PA levels, anthropometric measures, health-related quality of life (HRQoL), and blood biomarkers in breast cancer survivors. METHODS Eighty post-adjuvant therapy invasive breast cancer patients (age = 53.6 ± 9.4 years; height = 161.2 ± 6.8 cm; mass = 68.7 ± 10.5 kg) were randomly allocated to a 6-month home-based PA intervention or usual care. The intervention group received face-to-face and telephone PA counselling aimed at encouraging the achievement of current recommended PA guidelines. All patients were evaluated for our primary outcome, PA (International PA Questionnaire) and secondary outcomes, mass, BMI, body fat %, HRQoL (Functional assessment of Cancer Therapy-Breast), insulin resistance, triglycerides (TG) and total (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) cholesterol were assessed at baseline and at 6-months. RESULTS On the basis of linear mixed-model analyses adjusted for baseline values performed on 40 patients in each group, total, leisure and vigorous PA significantly increased from baseline to post-intervention in the intervention compared to usual care (between-group differences, 578.5 MET-min∙wk(-1), p = .024, 382.2 MET-min∙wk(-1), p = .010, and 264.1 MET-min∙wk(-1), p = .007, respectively). Both body mass and BMI decreased significantly in the intervention compared to usual care (between-group differences, -1.6 kg, p = .040, and -.6 kg/m(2), p = .020, respectively). Of the HRQoL variables, FACT-Breast, Trial Outcome Index, functional wellbeing, and breast cancer subscale improved significantly in the PA group compared to the usual care group (between-group differences, 5.1, p = .024; 5.6, p = .001; 1.9 p = .025; and 2.8, p = .007, respectively). Finally, TC and LDL-C was significantly reduced in the PA group compared to the usual care group (between-group differences, -.38 mmol∙L(-1), p = .001; and -.3 mmol∙L(-1), p = .023, respectively). CONCLUSIONS We found that home-based PA resulted in significant albeit small to moderate improvements in self-reported PA, mass, BMI, breast cancer specific HRQoL, and TC and LDL-C compared with usual care.

Abstract
Abstract
Background: Facilitating healthy levels of physical activity (PA) during chemotherapy is important for the psychosocial and physical health of breast cancer survivors. The primary objective of this feasibility study was to examine the effects of a broad-reach PA behavior change intervention among women with breast cancer receiving adjuvant chemotherapy.
Methods: Breast cancer patients receiving adjuvant chemotherapy (N = 95) were randomly assigned to receive a PA resource kit consisting of tailored print materials and a step pedometer (intervention) or a standard public health PA recommendation (standard recommendation). The primary outcome was daily pedometer steps. Secondary outcomes were self-reported light, moderate, and vigorous intensity PA, total moderate-to-vigorous PA, and sedentary time. Assessments were conducted before and after adjuvant chemotherapy.
Results: Attrition was 19% (17 of 95). Intervention patients wore their step pedometer for 85 days (range, 35–144 days; SD = 26.4) for a 95% adherence rate. Analyses of covariance suggested that the intervention was not statistically superior to standard recommendation for daily average pedometer steps (−771; 95% CI = −2024 to 482; P = 0.22), total MVPA minutes (−4; 95% CI = −62 to 570; P = 0.90), or sedentary time (+160; 95% CI = −186 to 506; P = 0.42).
Conclusion: This broach-reach and low intensive intervention was not more effective for promoting PA in breast cancer patients receiving chemotherapy than providing the standard public health guidelines for PA.
Impact: Achieving physical activity behavior change during adjuvant breast cancer chemotherapy may require some level of supervised physical activity or more intensive (e.g., face-to-face, supervised) interventions. Cancer Epidemiol Biomarkers Prev; 25(2); 391–8. ©2015 AACR.

Abstract
Answer questions and earn CME/CNE The importance of expanding cancer treatment to include the promotion of overall long-term health is emphasized in the Institute of Medicine report on delivering quality oncology care. Weight management, physical activity, and a healthy diet are key components of tertiary prevention but may be areas in which the oncologist and/or the oncology care team may be less familiar. This article reviews current diet and physical activity guidelines, the evidence supporting those recommendations, and provides an overview of practical interventions that have resulted in favorable improvements in lifestyle behavior change in cancer survivors. It also describes current lifestyle practices among cancer survivors and the role of the oncologist in helping cancer patients and survivors embark upon changes in lifestyle behaviors, and it calls for the development of partnerships between oncology providers, primary care providers, and experts in nutrition, exercise science, and behavior change to help positively orient cancer patients toward longer and healthier lives.

Abstract
PURPOSE Broad-reach (non-face-to-face) modalities offer an accessible and cost-effective means to provide behavior change programs in diverse and growing cancer survivor populations. The purpose of this systematic review is to evaluate the efficacy of physical activity, dietary, and/or weight control interventions for cancer survivors in which telephone, short-message service, print, and/or Web is the primary method of delivery. METHODS A structured search of PubMed, Embase, Web of Science, CINAHL, and CENTRAL (May 2013) was conducted. Included studies focused and reported on physical activity (PA) and dietary change and/or weight control in adult cancer survivors, delivered at least 50% of intervention contacts by broad-reach modality and included a control group. Study design, intervention features, and behavioral/weight outcomes were extracted, tabulated, and summarized. RESULTS Twenty-seven studies were included; 22 telephone, three Web, and two print. Sixteen studies targeted PA, two diet, and nine targeted multiple behaviors. Most studies (18/27) targeted a single survivor group, namely breast cancer (n = 12). Nineteen of 27 studies found evidence for initiation of behavior change, with only eight reporting on maintenance and one on cost-effectiveness. CONCLUSIONS This review provides support for broad-reach modalities, particularly the telephone, in the delivery of lifestyle interventions to cancer survivors. Future research should evaluate (1) newer technologies (i.e., SMS and mobile phone applications), (2) interventions for diverse cancer survivors and those targeting multiple behaviors, (3) long-term outcomes, and 4) cost-effectiveness. IMPLICATIONS FOR CANCER SURVIVORS Broad-reach lifestyle interventions are effective, with further research needed to evaluate their generalizability and integration into cancer care.

Abstract
UNLABELLED There has been an increase in the cancer survivor population in the United States over the past several decades primarily due to improvements in early detection of first malignancies and effective treatment modalities. A wealth of evidence has demonstrated that regular physical activity is associated with a lower risk of death, all-cause mortality, cancer recurrence, and several chronic diseases, including type 2 diabetes and cardiovascular disease, common comorbid conditions in people who have survived cancer. Physical activity also is a central component of weight management. METHODS This review summarizes the current physical activity recommendations and the evidence linking physical activity to improvements in weight management, physiological effects, and psychological health outcomes for cancer survivors. RESULTS The available literature suggests physical activity is safe and is positively associated with weight management, cardiorespiratory fitness, muscular strength and endurance, quality of life, fatigue, and other psychosocial factors in cancer survivors. Yet relationships related to specific cancer diagnoses, treatments, and underlying cardiometabolic mechanisms associated with survival have not been thoroughly examined in randomized controlled trials. Furthermore, factors that influence adherence to physical activity behaviors must be identified to develop effective exercise programs. The use of objective measures of physical activity and the standardization of reporting outcome measures within intervention trials are needed to complement this effort. CONCLUSIONS Healthcare providers should consider individual differences among cancer survivors and tailor physical activity programs to meet the individual needs of the patient to assist in the adoption and maintenance of a physically active lifestyle.

Abstract
Attachment theory provides a framework for understanding individual differences in chronic interpersonal stress. Attachment anxiety, a type of relationship insecurity characterized by worry about rejection and abandonment, is a chronic interpersonal stressor. Stress impacts cellular immunity, including herpesvirus reactivation. We investigated whether attachment anxiety was related to the expression of a latent herpesvirus, Epstein-Barr virus (EBV), when individuals were being tested for breast or colon cancer and approximately 1 year later. Participants (N=183) completed a standard attachment questionnaire and provided blood to assess EBV viral capsid antigen (VCA) IgG antibody titers. Individuals with more attachment anxiety had higher EBV VCA IgG antibody titers than those with less attachment anxiety. The strength of the association between attachment anxiety and antibody titers was the same at both assessments. This study is the first to show an association between latent herpesvirus reactivation and attachment anxiety. Because elevated herpesvirus antibody titers reflect poorer cellular immune system control over the latent virus, these data suggest that high attachment anxiety is associated with cellular immune dysregulation.

Abstract
BACKGROUND The health benefits of diet and exercise interventions for cancer survivors are well documented. However, little is known regarding demographic and medical predictors of survivors' willingness to participate in diet and exercise intervention trials, study enrollment, intervention adherence, and study completion. To assist in interpreting the generalizability of trial findings and to improve the design of future trials, this study examined predictors of these process measures. METHODS An integrative data analysis was performed on data from 3 of the largest home-based diet and exercise intervention trials for cancer survivors (n = 23,841). Demographic and medical factors (ie, sex, race, age, time since diagnosis, and cancer type) were examined as predictors of willingness to participate, study enrollment, intervention adherence, and study completion in the pooled sample. A 99% confidence interval was used to determine statistical significance. RESULTS Across trials, 11.1% of contacted survivors were willing to participate, and 5.7% were eligible and enrolled. Among enrollees, 53.4% demonstrated ≥75% adherence to the intervention, and 91.1% completed the study. Race (Caucasian vs others), age, time since diagnosis, and cancer type predicted survivors' willingness to participate (P < .01). All examined predictors were associated with the likelihood of study enrollment (P < .01). No significant predictors of intervention adherence or study completion were found among study enrollees (P ≥ .01). CONCLUSIONS Cancer survivors' demographic and medical characteristics predicted their interest and participation in diet and exercise intervention trials. These findings have implications for the generalizability of results and can help to guide procedures used in future trials to enhance patient representation.

Abstract
PURPOSE To evaluate yoga's impact on inflammation, mood, and fatigue. PATIENTS AND METHODS A randomized controlled 3-month trial was conducted with two post-treatment assessments of 200 breast cancer survivors assigned to either 12 weeks of 90-minute twice per week hatha yoga classes or a wait-list control. The main outcome measures were lipopolysaccharide-stimulated production of proinflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and interleukin-1β (IL-1β), and scores on the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF), the vitality scale from the Medical Outcomes Study 36-item Short Form (SF-36), and the Center for Epidemiological Studies-Depression (CES-D) scale. RESULTS Immediately post-treatment, fatigue was not lower (P > .05) but vitality was higher (P = .01) in the yoga group compared with the control group. At 3 months post-treatment, fatigue was lower in the yoga group (P = .002), vitality was higher (P = .01), and IL-6 (P = .027), TNF-α (P = .027), and IL-1β (P = .037) were lower for yoga participants compared with the control group. Groups did not differ on depression at either time (P > .2). Planned secondary analyses showed that the frequency of yoga practice had stronger associations with fatigue at both post-treatment visits (P = .019; P < .001), as well as vitality (P = .016; P = .0045), but not depression (P > .05) than simple group assignment; more frequent practice produced larger changes. At 3 months post-treatment, increasing yoga practice also led to a decrease in IL-6 (P = .01) and IL-1β (P = .03) production but not in TNF-α production (P > .05). CONCLUSION Chronic inflammation may fuel declines in physical function leading to frailty and disability. If yoga dampens or limits both fatigue and inflammation, then regular practice could have substantial health benefits.

Abstract
BACKGROUND Multidimensional rehabilitation programmes (MDRPs) have developed in response to the growing number of people living with and surviving cancer. MDRPs comprise a physical component and a psychosocial component. Studies of the effectiveness of these programmes have not been reviewed and synthesised. OBJECTIVES To conduct a systematic review of studies examining the effectiveness of MDRPs in terms of maintaining or improving the physical and psychosocial well-being of adult cancer survivors. SEARCH METHODS We conducted electronic searches in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsychINFO up to February 2012. SELECTION CRITERIA Selection criteria focused on randomised controlled trials (RCTs) of multidimensional interventions for adult cancer survivors. Interventions had to include a physical component and a psychosocial component and to have been carried out on two or more occasions following completion of primary cancer treatment. Outcomes had to be assessed using validated measures of physical health and psychosocial well-being. Non-English language papers were included. DATA COLLECTION AND ANALYSIS Pairs of review authors independently selected trials, rated their methodological quality and extracted relevant data. Although meta-analyses of primary and secondary endpoints were planned there was a high level of study heterogeneity and only one common outcome measure (SF-36) could be statistically synthesised. In addition, we conducted a narrative analysis of interventions, particularly in terms of inspecting and identifying intervention components, grouping or categorising interventions and examining potential common links and outcomes. MAIN RESULTS Twelve RCTs (comprising 1669 participants) met the eligibility criteria. We judged five studies to have a moderate risk of bias and assessed the remaining seven as having a high risk of bias. It was possible to include SF-36 physical health component scores from five studies in a meta-analysis. Participating in a MDRP was associated with an increase in SF-36 physical health component scores (mean difference (MD) 2.22, 95% confidence interval (CI) 0.12 to 4.31, P = 0.04). The findings from the narrative analysis suggested that MDRPs with a single domain or outcome focus appeared to be more successful than programmes with multiple aims. In addition, programmes that comprised participants with different types of cancer compared to cancer site-specific programmes were more likely to show positive improvements in physical outcomes. The most effective mode of service delivery appeared to be face-to-face contact supplemented with at least one follow-up telephone call. There was no evidence to indicate that MDRPs which lasted longer than six months improved outcomes beyond the level attained at six months. In addition, there was no evidence to suggest that services were more effective if they were delivered by a particular type of health professional. AUTHORS' CONCLUSIONS There is some evidence to support the effectiveness of brief, focused MDRPs for cancer survivors. Rigorous and methodologically sound clinical trials that include an economic analysis are required.

Psychoneuroendocrinology 2013; 38:179-87.

Abstract
Cigarette smoking continues to be the most preventable cause of illness and death and has been linked to the development and prognosis of cancer. Current smokers have higher levels of inflammation than nonsmokers, and inflammation can remain elevated in former smokers even years following cessation. Inflammation can also be enhanced by stress. This study examined cortisol and inflammatory responses to a laboratory stressor in breast cancer survivors who formerly smoked compared to their counterparts who had never smoked. Participants included 89 women (age=51.6±8.9 years) who had completed treatment for stage 0-IIIA breast cancer within the past three years and were at least two months post surgery, radiation or chemotherapy, whichever occurred last. Cortisol and interleukin-6 (IL-6) were evaluated in response to a standardized laboratory speech and mental arithmetic stressor. Former (n=25) and never (n=64) smokers did not differ by cancer stage, cancer treatment, comorbidities, time since cancer treatment, depression, or stress. Despite having similar cortisol responses to the stressor, former smokers had exaggerated IL-6 responses two hours post-stressor compared to never smokers. This effect persisted after controlling for age, BMI, time since treatment, education, and antidepressant use. An exaggerated and prolonged inflammatory response to stress could be one mechanism underlying the persistent inflammation observed in former smokers.

Abstract
BACKGROUND Breast cancer is the most commonly diagnosed cancer among women in the United States. Extensive research has been completed to evaluate the relationship between dietary factors and breast cancer risk and survival after breast cancer; however, a summary report with clinical inference is needed. Materials and METHODS This review summarizes the current epidemiological and clinical trial evidence relating diet to breast cancer incidence, recurrence, survival, and mortality. The review includes emerging epidemiological studies that assess risk within breast cancer subtypes as well as a summary of previous and ongoing dietary intervention trials designed to modify breast cancer risk. RESULTS The available literature suggests that both low-fat and high-fiber diets may be weakly protective against breast cancer, whereas total energy intake and alcohol appear to be positively associated. Fiber may be weakly protective possibly through modulation of estrogen, whereas fruit and vegetable intake is not clearly associated with risk. Obesity is a risk factor for postmenopausal disease, and adult weight gain should be avoided to reduce risk. In survivors, diet has the greatest potential influence on overall mortality rather than breast cancer-specific events. CONCLUSION Diet is modestly associated with breast cancer risk; associations appear more pronounced for postmenopausal disease, and healthy choices after diagnosis and treatment likely support longevity more so than reduced risk for recurrent disease.

Abstract
BACKGROUND Breast cancer is the most common malignancy in women worldwide. Multidisciplinary rehabilitation aims to improve outcomes for women but the evidence base for its effectiveness is yet to be established. OBJECTIVES To assess the effects of organised multidisciplinary rehabilitation during follow-up in women treated for breast cancer. SEARCH METHODS We searched the Cochrane Breast Cancer Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, CINAHL, AMED, PEDro and LILACS in December 2011. SELECTION CRITERIA Randomised and controlled clinical trials (RCTs, CCTs, respectively) that compared multidisciplinary rehabilitation with some form of control intervention (such as a lower level or different type of intervention, minimal intervention, waiting list controls or no treatment, interventions given in different settings). DATA COLLECTION AND ANALYSIS The type of data retrieved did not allow for quantitative synthesis and therefore a narrative synthesis was provided. The methodological quality of the included studies was evaluated by three authors using the risk of bias tool. MAIN RESULTS Two RCTs, including 262 participants, met the inclusion criteria. Both trials scored poorly for methodological quality. There was 'low level' evidence that multidisciplinary rehabilitation produced short-term gains at the levels of impairment (that is range of shoulder movement), psychosocial adjustment and quality of life after breast cancer treatment (up to 12 months). No evidence was available for the longer-term functional outcomes for caregivers or the cost effectiveness of these programmes. It was not possible to suggest the most appropriate frequency and duration of therapy or choice of one type of intervention over another. AUTHORS' CONCLUSIONS There was 'low level' evidence that multidisciplinary rehabilitation can improve the outcomes of people with breast cancer in terms of functional ability, psychosocial adjustment and participation in social activities. There was no evidence available on functional gain at the level of activity. This review highlights the limitations of RCTs in rehabilitation settings and the need for high-quality trial-based research in this area. Regular evaluation and assessment of breast cancer survivors for rehabilitation is recommended.

Abstract
PURPOSE Maintaining physical activity and dietary improvements achieved during an intervention is important for the long-term health outcomes of breast cancer survivors. This review aimed to determine: (a) the proportion of physical activity and/or dietary intervention trials in breast cancer survivors that assessed post-intervention maintenance of outcomes, (b) the proportion of trials that achieved successful post-intervention maintenance of outcomes, and (c) the sample, intervention, and methodological characteristics common among trials that achieved successful post-intervention maintenance of outcomes. METHODS A structured search of PubMed, CINAHL, Medline via Ovid, Web of Science, CENTRAL, and PsycInfo was conducted for articles published until March 2012. Included trials had to evaluate a randomized controlled trial of a physical activity and/or dietary behavior change intervention that targeted breast cancer survivors and report on between-group differences of behavioral outcomes at end-of-intervention and at least 3 months post-intervention follow-up. Methodological quality of included trials was also assessed. RESULTS The search resulted in 1,298 publications. Of 63 identified trials that assessed end-of-intervention outcomes, 10 (16 %) assessed post-intervention maintenance of outcomes; four of these 10 trials achieved successful maintenance. Due to the limited number and heterogeneity of the four trials, few commonalities in sample, intervention, and methodological characteristics were identified. CONCLUSION Assessing post-intervention maintenance of physical activity and dietary outcomes in breast cancer survivors is rare. There is a pressing need to direct more attention to this issue to inform the development of interventions to improve the long-term health outcomes for the growing number of breast cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS For breast cancer survivors, maintaining regular physical activity and a healthy diet are important to enhancing health and well-being over the long-term. More research is needed to identify the best ways of supporting survivors to make and maintain these lifestyle changes.

Abstract
CONTEXT Child emotional maltreatment can result in lasting immune dysregulation that may be heightened in the context of more recent life stress. Basal cell carcinoma (BCC) is the most common skin cancer, and the immune system plays a prominent role in tumor appearance and progression. OBJECTIVE To address associations among recent severe life events, childhood parental emotional maltreatment, depression, and messenger RNA (mRNA) coding for immune markers associated with BCC tumor progression and regression. DESIGN We collected information about early parent-child experiences, severe life events in the past year as assessed by the Life Events and Difficulties Schedule, depression, and mRNA for immune markers associated with BCC tumor progression and regression from patients with BCC tumors. SETTING University medical center. PARTICIPANTS Ninety-one patients with BCC (ages, 23-92 years) who had a previous BCC tumor. MAIN OUTCOME MEASURES The expression of 4 BCC tumor mRNA markers (CD25, CD3ε, intercellular adhesion molecule 1, and CD68) that have been linked to BCC tumor progression and regression were assessed in BCC tumor biopsy specimens. RESULTS Both maternal and paternal emotional maltreatment interacted with the occurrence of severe life events to predict the local immune response to the tumor (adjusted P = .009 and P = .03, respectively). Among BCC patients who had experienced a severe life event within the past year, those who were emotionally maltreated by their mothers (P = .007) or fathers (P = .02) as children had a poorer immune response to the BCC tumor. Emotional maltreatment was unrelated to BCC immune responses among those who did not experience a severe life event. Depressive symptoms were not associated with the local tumor immune response. CONCLUSIONS Troubled early parent-child relationships, in combination with a severe life event in the past year, predicted immune responses to a BCC tumor. The immunoreactivity observed in BCCs and the surrounding stroma reflects an anti-tumor-specific immune response that can be altered by stress.

Abstract
BACKGROUND Cancer survivors experience numerous disease and treatment-related adverse outcomes and poorer health-related quality of life (HRQoL). Exercise interventions are hypothesized to alleviate these adverse outcomes. HRQoL and its domains are important measures for cancer survivorship. OBJECTIVES To evaluate the effectiveness of exercise on overall HRQoL and HRQoL domains among adult post-treatment cancer survivors. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, PEDRO, LILACS, SIGLE, SportDiscus, OTSeeker, and Sociological Abstracts from inception to October 2011 with no language or date restrictions. We also searched citations through Web of Science and Scopus, PubMed's related article feature, and several websites. We reviewed reference lists of included trials and other reviews in the field. SELECTION CRITERIA We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing exercise interventions with usual care or other nonexercise intervention to assess overall HRQoL or at least one HRQoL domain in adults. Included trials tested exercise interventions that were initiated after completion of active cancer treatment. We excluded trials including people who were terminally ill, or receiving hospice care, or both, and where the majority of trial participants were undergoing active treatment for either the primary or recurrent cancer. DATA COLLECTION AND ANALYSIS Five paired review authors independently extracted information on characteristics of included trials, data on effects of the intervention, and assessed risk of bias based on predefined criteria. Where possible, meta-analyses results were performed for HRQoL and HRQoL domains for the reported difference between baseline values and follow-up values using standardized mean differences (SMD) and a random-effects model by length of follow-up. We also reported the SMDs between mean follow-up values of exercise and control group. Because investigators used many different HRQoL and HRQoL domain instruments and often more than one for the same domain, we selected the more commonly used instrument to include in the SMD meta-analyses. We also report the mean difference for each type of instrument separately. MAIN RESULTS We included 40 trials with 3694 participants randomized to an exercise (n = 1927) or comparison (n = 1764) group. Cancer diagnoses in study participants included breast, colorectal, head and neck, lymphoma, and other. Thirty trials were conducted among participants who had completed active treatment for their primary or recurrent cancer and 10 trials included participants both during and post cancer treatment. Mode of the exercise intervention included strength training, resistance training, walking, cycling, yoga, Qigong, or Tai Chi. HRQoL and its domains were measured using a wide range of measures.The results suggested that exercise compared with control has a positive impact on HRQoL and certain HRQoL domains. Exercise resulted in improvement in: global HRQoL at 12 weeks' (SMD 0.48; 95% confidence interval (CI) 0.16 to 0.81) and 6 months' (0.46; 95% CI 0.09 to 0.84) follow-up, breast cancer concerns between 12 weeks' and 6 months' follow-up (SMD 0.99; 95% CI 0.41 to 1.57), body image/self-esteem when assessed using the Rosenberg Self-Esteem scale at 12 weeks (MD 4.50; 95% CI 3.40 to 5.60) and between 12 weeks' and 6 months' (mean difference (MD) 2.70; 95% CI 0.73 to 4.67) follow-up, emotional well-being at 12 weeks' follow-up (SMD 0.33; 95% CI 0.05 to 0.61), sexuality at 6 months' follow-up (SMD 0.40; 95% CI 0.11 to 0.68), sleep disturbance when comparing follow-up values by comparison group at 12 weeks' follow-up (SMD -0.46; 95% CI -0.72 to -0.20), and social functioning at 12 weeks' (SMD 0.45; 95% CI 0.02 to 0.87) and 6 months' (SMD 0.49; 95% CI 0.11 to 0.87) follow-up. Further, exercise interventions resulted in decreased anxiety at 12 weeks' follow-up (SMD -0.26; 95% CI -0.07 to -0.44), fatigue at 12 weeks' (SMD -0.82; 95% CI -1.50 to -0.14) and between 12 weeks' and 6 months' (SMD -0.42; 95% CI -0.02 to -0.83) follow-up, and pain at 12 weeks' follow-up (SMD -0.29; 95% CI -0.55 to -0.04) when comparing follow-up values by comparison group.Positive trends and impact of exercise intervention existed for depression and body image (when analyzing combined instruments); however, because few studies measured these outcomes the robustness of findings is uncertain.No conclusions can be drawn regarding the effects of exercise interventions on HRQoL domains of cognitive function, physical functioning, general health perspective, role function, and spirituality.Results of the review need to be interpreted cautiously owing to the risk of bias. All the trials reviewed were at high risk for performance bias. In addition, the majority of trials were at high risk for detection, attrition, and selection bias. AUTHORS' CONCLUSIONS This systematic review indicates that exercise may have beneficial effects on HRQoL and certain HRQoL domains including cancer-specific concerns (e.g. breast cancer), body image/self-esteem, emotional well-being, sexuality, sleep disturbance, social functioning, anxiety, fatigue, and pain at varying follow-up periods. The positive results must be interpreted cautiously due to the heterogeneity of exercise programs tested and measures used to assess HRQoL and HRQoL domains, and the risk of bias in many trials. Further research is required to investigate how to sustain positive effects of exercise over time and to determine essential attributes of exercise (mode, intensity, frequency, duration, timing) by cancer type and cancer treatment for optimal effects on HRQoL and its domains.

Abstract
BACKGROUND Physical activity decreases risk of colon polyps and colon cancer and might reduce risk of colon cancer recurrence. Focusing on recent calls for translation of epidemiologic evidence into clinical care, our pilot study delivered an evidence-based physical activity intervention in adults with polyps, who are thus at elevated risk of developing colon cancer. The objective was to evaluate change in physical activity, measured by steps per day and minutes of moderate/vigorous physical activity. METHODS Sixteen adults with adenomas detected and removed at screening colonoscopy were recruited to a 12-week physical activity intervention. Participants were randomized to receive a standard (30 minutes/day) or high (60 minutes/day) walking program. Physical activity was measured via blinded pedometer and accelerometer at baseline and follow-up. Intervention messages focused on self-monitoring using pedometers and overcoming barriers to engaging in physical activity. RESULTS Participants in both arms significantly increased objectively measured minutes of moderate/vigorous physical activity over the course of the intervention. Both arms exceeded the intervention goal, but there was not a significant difference between arms at follow-up. Results were similar for pedometer measured physical activity, with a significant overall increase in steps/day from baseline to follow-up, but no between arm difference in change. CONCLUSION Simple interventions of minimal contact time focusing on walking can significantly increase physical activity in individuals at increased risk of developing colon cancer.

Abstract
BACKGROUND Older adult cancer survivors are at greater risk of cancer recurrence and other comorbidities that can be prevented through improved diet and weight management. The tertiary prevention needs of rural-dwelling survivors can be even greater, yet little is known about rural and urban differences in lifestyle factors among this high-risk population. OBJECTIVES To compare dietary patterns of urban and rural cancer survivors and to examine associations of dietary patterns with body mass index (BMI). DESIGN A secondary analysis was performed of baseline data from the Reach Out to Enhance Wellness (RENEW) trial, a diet and exercise intervention among overweight, long-term (≥5 years), older survivors of colorectal, breast, and prostate cancer. Survivors in the present analysis (n=729) underwent two 45- to 60-minute telephone surveys, which included two 24-hour dietary recalls. Principal components analysis and multivariable general linear models were used to derive dietary patterns and to evaluate associations between dietary patterns and BMI, respectively. RESULTS Principal components analysis identified three primary dietary patterns among rural dwellers (high sweets and starches, high reduced-fat dairy, cereal, nuts, and fruits, and mixed) and three among urban dwellers (high fruits and vegetables, high meat and refined grains, and high sugar-sweetened beverages). Among rural survivors, greater adherence to the high reduced-fat dairy, cereal, nuts, and fruits pattern was positively associated with lower BMI (P trend <0.05), whereas higher scores on the mixed pattern was associated with greater BMI (P trend <0.05). Greater adherence to the high fruits and vegetables pattern among urban survivors was inversely associated with BMI (P trend <0.05). CONCLUSIONS Urban and rural differences in dietary intake behavior should be considered in designing public health interventions among the increasing population of older cancer survivors. In addition, targeting overall dietary patterns might be one approach to help reduce the burden of obesity among this population.

Abstract
Fatigue is a notable clinical problem in cancer survivors, and understanding its pathophysiology is important. The current study sought to determine biomarkers of fatigue that exist before cancer treatment. Relationships between the expression of latent Epstein-Barr virus (EBV) and cytomegalovirus (CMV) and fatigue were examined in 158 women newly diagnosed with breast cancer or awaiting a positive diagnostic result. Higher CMV antibody titers, but not EBV antibody titers, were associated with a greater likelihood of being fatigued. Associations between fatigue and higher CMV antibody titers remained after controlling for alcohol use, smoking, comorbidities, depressive symptoms, age, BMI, cancer stage, and sleep problems. More sleep problems and higher levels of depressive symptoms were also associated with a greater likelihood of being fatigued. CMV antibody titers, but not EBV antibody titers, were associated with higher levels of C-reactive protein (CRP), but CRP was not associated with fatigue. When the cellular immune system is compromised, reactivation of latent herpesviruses may fuel chronic inflammatory responses. Prior work has suggested that fatigue may be related to inflammation and its associated sickness behaviors; accordingly, our findings may be tapping into this same physiological substrate.

Abstract
OBJECTIVE Both higher socioeconomic status (SES) and supportive personal relationships confer health benefits, including better immune function. This study assessed the joint impact of SES and social support on the expression of a latent herpesvirus, Epstein-Barr virus (EBV), in a group of highly stressed women. METHODS Two-hundred and twenty four women either awaiting further evaluation following an abnormal mammogram or newly diagnosed with breast cancer completed questionnaires and provided blood samples to assess EBV viral capsid antigen (VCA) IgG antibody titers. RESULTS More highly educated women with more support from friends had lower EBV VCA antibody titers, reflecting a stronger cellular immune response to the latent virus; however, among less educated women, friend support was not associated with EBV antibody titers. As revealed in an ancillary analysis, more highly educated women with more friend support had lower systolic blood pressure (SBP); however, friend support was not associated with SBP among less educated women. Neither depression nor perceived stress mediated these associations. Neither cancer status nor cancer stage among those diagnosed with cancer was significantly related to these outcomes. CONCLUSION Lower SES women may not reap the same immunological benefits from friend support when experiencing a stressful life event as their higher SES counterparts.

Abstract
Fatigue is a notable clinical problem in cancer survivors, and understanding its pathophysiology is important. This study evaluated relationships between fatigue and both sympathetic and parasympathetic nervous system activity in breast cancer survivors. Norepinephrine and heart rate variability (HRV) were evaluated at rest, as well as during and after a standardized laboratory speech and mental arithmetic stressor. The participants, 109 women who had completed treatment for stage 0-IIIA breast cancer within the past two years, were at least two months post surgery, radiation or chemotherapy, whichever occurred last. Women who reported more fatigue had significantly higher norepinephrine and lower HRV before and after the stressor than their less fatigued counterparts. Fatigue was not related to treatment or disease variables including treatment type, cancer stage, time since diagnosis, and time since treatment. Importantly, the relationship between HRV and cancer-related fatigue was sizeable. Based on research that has demonstrated characteristic age-related HRV decrements, our findings suggest a 20-year difference between fatigued and non-fatigued cancer survivors, raising the possibility that fatigue may signify accelerated aging. Furthermore, lower HRV and elevated norepinephrine have been associated with a number of adverse health outcomes; accordingly, fatigue may also signal the need for increased vigilance to other health threats.

Abstract
OBJECTIVES To test a tool-kit designed to improve well-being in patients with prostate cancer. Lifestyle changes might lessen the metabolic, cardiovascular, and osseous side effects of androgen deprivation therapy (ADT) in prostate cancer patients. METHODS Urologists supplied 10 consecutive patients initiating ADT with a tool-kit (information brochure, practical guidance on diet and exercise, recipe booklet, and lifestyle diary). The urologists completed a total 4 questionnaires, at study initiation, one at the patients' first and second visits, and one at study completion. RESULTS Overall, 91 urologists completed all questionnaires; 585 patients (median age, 75 years) were seen at the first visit, and 511 patients at the second. Patient response rate to the first questionnaire was 62% and 56% to the second. After the first visit, 82% of respondents reported being very glad or glad to receive the kit; among those having read the practical guidance (301/362), 57% had started implementation and 36% intended to do so. After the second visit, 76% were satisfied with the tool-kit and 84% were implementing guidance. Clinician satisfaction rate was 82%: benefits were improved patient dialogue (62%), follow-up (55%), and better explanation of side effects (51%). Only 14 clinicians were not pleased by the tool kit. Their main criticisms (too long, tedious, not tailored to individual needs) matched those of patients. CONCLUSIONS Written detailed guidance on diet and physical exercise for patients about to receive ADT met a genuine need and was well perceived by both clinicians and patients. Implementation rate was high. However, content should be adapted to patient age and disease stage.

Abstract
Physical activity (PA) participation has been shown to be helpful in improving physical and mental well-being among cancer survivors. The purpose of this chapter is to review the literature on the determinants of physical activity motivation and behavior among cancer survivors. Using theories of behavior change, researchers have sought to identify the correlates of motivation that predict the participation in regular physical activity in observational studies, while intervention studies have focused on manipulating those factors to support the initiation of physical activity. The majority of this work has been conducted with breast cancer survivors, and there is an interest in expanding this work to survivors of others cancers (e.g., prostate, lung, and colorectal cancer). Results suggest that constructs from the Theory of Planned Behavior (TPB), Transtheoretical Model (TTM), and Social Cognitive Theory (SCT) are associated with greater motivation for physical activity, and some of these constructs have been used in interventions to promote physical activity adoption. There is scope for understanding the determinants of physical activity adoption in various cancer survivor populations. Much more needs to done to identify the determinants of maintenance of physical activity.

Abstract
PURPOSE There is increased interest in developing and disseminating health behavior interventions for cancer survivors. Challenges in these efforts include participant burden in traveling to central intervention sites and sustainability. The purpose of this article is to report various methods used to recruit breast cancer survivors into an exercise intervention that attempts to address both of these challenges. METHODS Letters were mailed within specific zip codes near community-based intervention sites in cooperation with state cancer registries. Additional recruitment methods included flyers at breast care clinics and support groups, mass media, and conferences. RESULTS Of the 3200 women who responded, 82% (n = 2625) identified having heard about the study through state or hospital registry and 8% (n = 243) through print and broadcast media. Thirty-five percent (n = 103) of randomized women self-identified as having a minority racial background and 31.9% (n = 94) self-identified as African American. Comparisons of participant age and racial distribution to state cancer registries indicate similar age distribution but greater racial diversity among participants. CONCLUSION These results support the use of population-based cancer registries to recruit survivors into community-based interventions and clinical trials.

Abstract
CONTEXT Five-year survival rates for early stage colorectal, breast, and prostate cancer currently exceed 90% and are increasing. Cancer survivors are at greater risk for second malignancies, other comorbidities, and accelerated functional decline. Lifestyle interventions may provide benefit, but it is unknown whether long-term cancer survivors can modify their lifestyle behaviors sufficiently to improve functional status. OBJECTIVE To determine whether a telephone counseling and mailed print material-based diet and exercise intervention is effective in reorienting functional decline in older, overweight cancer survivors. DESIGN, SETTING, AND PARTICIPANTS Randomized controlled trial of 641 overweight (body mass index > or = 25 and < 40), long-term (> or = 5 years) survivors (aged 65-91 years) of colorectal, breast, and prostate cancer, who were randomly assigned to an intervention group (n = 319) or delayed intervention (control) group (n = 322) in Canada, the United Kingdom, and 21 US states. Individuals were recruited for the Reach out to Enhance Wellness (RENEW) trial from July 1, 2005, through May 17, 2007. INTERVENTION A 12-month, home-based tailored program of telephone counseling and mailed materials promoting exercise, improved diet quality, and modest weight loss. The control group was wait-listed for 12 months. MAIN OUTCOME MEASURES Change in self-reported physical function on the Short-Form 36 physical function subscale (score range, 0-100; a high score indicates better functioning) from baseline to 12 months was the primary end point. Secondary outcomes included changes in function on the basic and advanced lower extremity function subscales of the Late Life Function and Disability Index (score range, 0-100), physical activity, body mass index, and overall health-related quality of life. RESULTS The mean baseline Short-Form 36 physical function score was 75.7. At the 12-month follow-up, the mean function scores declined less rapidly in the intervention group (-2.15; 95% confidence interval [CI], -0.36 to -3.93) compared with the control group (-4.84; 95% CI, -3.04 to -6.63) (P = .03). The mean baseline basic lower extremity function score was 78.2. The mean changes in basic lower extremity function were 0.34 (95% CI, -0.84 to 1.52) in the intervention group compared with -1.89 (95% CI, -0.70 to -3.09) in the control group (P = .005). Physical activity, dietary behaviors, and overall quality of life increased significantly in the intervention group compared with the control group, and weight loss also was greater (2.06 kg [95% CI, 1.69 to 2.43 kg] vs 0.92 kg [95% CI, 0.51 to 1.33 kg], respectively; P < .001). CONCLUSION Among older, long-term survivors of colorectal, breast, and prostate cancer, a diet and exercise intervention reduced the rate of self-reported functional decline compared with no intervention.

Abstract
Many published articles have documented the impact of prostate-cancer treatment on sexual functioning in men treated for localized disease. Surprisingly, the literature on interventions to rehabilitate men's sexual functioning is much more limited. In this article, we review the sexual-rehabilitation interventions for prostate-cancer patients and identify a number of common themes across interventions. We also identify areas where further research is needed and propose a conceptual model based on psychologic and nursing theories and informed by the published research.

Abstract
OBJECTIVES To review the theories that have been the basis for randomized controlled trials (RCTs) promoting health behavior change among adults diagnosed and treated for cancer. DATA SOURCES Electronic databases and recent review papers. CONCLUSION Several theories have been used in intervention development: Transtheoretical Model, Motivational Interviewing, Social Learning and Social Cognitive Theory, Theory of Planned Behavior, and Cognitive Behavioral Theory. There is support for the efficacy of some of these interventions. However, there has been limited assessment of theory-based constructs and examination of the mediational role of theoretical constructs in intervention efficacy. IMPLICATIONS FOR NURSING PRACTICE There is a need to apply theory in the development of interventions to assess the effects of the intervention on the constructs and to conduct mediational tests of these constructs.

RESULTS At baseline, individuals reporting 150 minutes or more of moderate PA/week had mean PF scores that were 20.3 points higher than those who did not (P<.001). Change in PA minutes from above threshold to below threshold or from below threshold to above threshold from baseline to 6 months resulted in an average change in PF of -11.18 (P<.001) and +5.10 (P=.05), respectively. CONCLUSION These findings suggest that PA is an important predictor of functional status. Older sedentary adults can improve PF by meeting recommended PA levels. Conversely, dropping below recommended PA levels has a deleterious effect on PF. Given the importance of PF in maintenance of independence and quality of life in older adults, adherence to recommended PA guidelines should be endorsed.

Abstract
Providing effective and tolerable cancer treatment for the growing number of older adult patients who have cancer requires an understanding of the role of aging, comorbidity, functional status, and frailty on treatment outcomes. The incorporation of comprehensive geriatric assessment (CGA) into the care of older patients who have cancer ensures that the cognitive, physical, and psychosocial strengths and limitations of individual patients are considered in the development of treatment plans. CGA also may improve outcomes by identifying and optimally treating comorbid conditions and functional impairments. Optimal treatment of the older adult patient who has cancer starts with careful delineation of goals through conversation. The treatment plan should be comprehensive and address cancer-specific treatment, symptom-specific treatment, supportive treatment modalities, and end-of-life care.

Abstract
OBJECTIVES To review randomized controlled trials that offered exercise interventions for adults diagnosed and treated for cancer related to design, sample, type of intervention, and outcomes. DATA SOURCES Several electronic databases were searched and recent review papers were scanned to identify relevant publications. CONCLUSION Exercise adoption seems clearly feasible for early stage cancer patients, particularly breast cancer patients. Data support positive effects for physical functioning, quality of life, and psychological well-being. Effects for patients with later-stage disease and other cancers are less clear. The impact of exercise adoption on biomarkers of disease status, immune functioning, and hormone levels should also be examined. IMPLICATIONS FOR NURSING PRACTICE There are many opportunities for nurses to promote exercise in clinical care and in a research context.

Abstract
PURPOSE/OBJECTIVES To describe health behaviors of cancer survivors by cancer diagnosis and to compare them to people without a personal or family cancer history. DESIGN Cross-sectional secondary data analysis. SETTING A national, list-assisted telephone survey using random-digit dialing of U.S. adults about use of cancer-related information and cancer beliefs. SAMPLE 619 cancer survivors and 2,141 participants without a history of cancer from the original 6,369 Health Information National Trends Survey (HINTS) respondents. METHODS Using the National Cancer Institute's 2003 HINTS, further analyses were conducted. MAIN RESEARCH VARIABLES Cancer history, current smoking, fruit and vegetable consumption, physical activity, and body mass index (BMI). FINDINGS When controlling for demographic variables, no differences were found in self-reported health behaviors between survivors and those without cancer: 22.5% of survivors and 18.4% of those without cancer were current smokers, 18% of survivors and 14.9% of those without cancer consumed at least five fruits or vegetables per day, 45.3% of survivors and 53% of those without cancer were physically active at least weekly, and 58% of survivors and 54.9% of those without cancer were overweight or obese (i.e., BMI > 25). Only 7.4% of survivors and 6.4% of participants without cancer reported positively on all three health behaviors and had a healthy or normal weight. CONCLUSIONS Survivors did not have different health behaviors when compared to participants without a history of cancer. Neither group met the American Cancer Society or Healthy People 2010 objectives for these behaviors. Adoption of healthy lifestyle behaviors should be addressed in cancer survivors. IMPLICATIONS FOR NURSING Cancer survivors need to be assessed for current smoking, dietary habits, physical activity, and weight. Information and resources should be made available, if needed, to promote the adoption of healthy lifestyle behaviors.

The Diet Quality Index-Revised: A Tool to Promote and Evaluate Dietary Change among Older Cancer Survivors Enrolled in a Home-Based Intervention Trial. ACTA ACUST UNITED AC 2007; 107:1519-29.

Abstract
OBJECTIVE To utilize the Diet Quality Index-Revised (DQI-R) as a framework for delivering and evaluating an intervention to improve overall diet quality among older cancer survivors. DESIGN As part of a randomized controlled trial to improve lifestyle behaviors among older cancer survivors, we sought a dietary measure that could serve as both an intervention framework and a means to evaluate global dietary quality. The DQI-R measures overall diet quality by summing 10 subscales that relate to national guidelines. At baseline, DQI-R scores were generated from three multi-pass 24-hour dietary recalls. The 6-month intervention delivered tailored feedback on individual DQI-R subscales. Dietary recalls were repeated at 6 and 12 months. SUBJECTS Elderly (aged >or=65 years) individuals within 18 months of diagnosis of breast or prostate cancer (n=182) were randomized postbaseline measures to intervention vs attention control arms. RESULTS Significant differences in overall diet quality were observed between arms at 6 months, with the intervention arm improving (67.6+/-12.2 to 69.8+/-13.9), and controls declining (67.5+/-12.5 to 64.6+/-14.7) (P=0.003). Significant differences were observed between arms over time in dietary diversity subscale scores: baseline and 6-month follow-up means among intervention and control arms were 4.8+/-1.3 to 4.8+/-1.4, and 4.7+/-1.2 to 4.1+/-1.1, respectively (P=0.001). CONCLUSIONS The DQI-R served as an effective guide and evaluation tool for this diet-related randomized controlled trial. Like many interventions, our effect diminished after the intervention was complete. Future research should consider testing interventions that use the DQI-R, or other global diet-related indexes, as guides and evaluation tools over longer study periods, as well as in other populations.

Abstract
Loss of bone mineral density (BMD) is a significant problem for women receiving breast cancer treatment. The purpose of this article is to present the state of the knowledge on BMD loss and analyze interventions to prevent BMD loss in women receiving breast cancer treatment. The data sources include primary research reports, review articles, and book chapters. With increased numbers of breast cancer survivors, BMD loss experienced with treatment is a significanthealth concern because of risks of osteoporosis and bone fractures. These long-term treatment effects may significantly impact patients' long-term morbitity and mortality. BMD screening as well as an assessment of physical activity and dietary history should be conducted with women undergoing breast cancer treatment. Bisphosphonates are effective in preventing BMD loss, and other interventions such as physical activity and dietary interventions need further testing. Oncology nurses are ideal candidates for implementing interventions to prevent BMD loss because of their understanding of cancer treatments, knowledge of health-related behaviors, and ability to teach patients about the positive health benefits of lifestyle changes.

Abstract
This review describes the definitions of sedentary used to screen community-dwelling adults in physical-activity-intervention trials published from 2000 to 2005. Results of 42 trials showed that definitions of sedentary varied from <20 to <150 min/week of physical activity, and few reported the type (work, household, or leisure) or intensity of activity that was used to screen participants. The range of "sedentary" samples makes it difficult to compare trial results or generalize findings. Published reports of exercise trials would be more useful to practitioners and researchers if they included an explicit description of the cut point used to define sedentary adults in the sample, in terms of maximum minutes or days per week of activity and the wording of the screening measure in terms of type and intensity of activity.
