Background: Assessing the survival benefit of neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC) patients is typically evaluated through clinical trials. Clinical trials are limited by their highly controlled context, often limiting the generalisability of findings. Globally, there is a lack of population-based evaluations of ‘o...
Purpose
The association between obesity and triple-negative breast cancer (TNBC) prognosis has been equivocal, with considerable heterogeneity between and within studies. Recent meta-analyses report adverse associations with overall survival (OS) and disease-free survival (DFS) in TNBC. We update this evidence and examine study- and disease-specifi...
Purpose
To examine eating frequency, timing of meals, and sleep duration before and after a weight loss intervention for breast cancer survivors.
Methods
Female breast cancer survivors (n = 159; 55 ± 9 years; 31.4 ± 5.0 kg/m²; stage I–III, median [IQR] 9.5 [5.5] months post-diagnosis) participated in a randomized controlled trial of a 12-month wei...
Objective
Postpartum depression (PPD) has deleterious effects on both maternal and child outcomes. Poor maternal nutrition during pregnancy has been implicated in the development of PPD. This review aimed to explore the association between the overall dietary intake patterns during pregnancy and the development of PPD.
Methods
A literature search...
Purpose
Circadian rhythm disruptors (e.g., night-shift work) are risk factors for breast cancer, however studies on their association with prognosis is limited. A small but growing body of research suggests that altered sleep patterns and eating behaviours are potential mechanistic links between circadian rhythm disruptors and breast cancer. We the...
Background
Diet, exercise, and weight management are key in improving outcomes for breast cancer survivors, with international recommendations for cancer survivors relating to these behaviors. However, few behavioral interventions have reported outcomes aligned specifically with these recommendations.
Objective
To evaluate a remotely delivered wei...
Limited evidence exists on the effects of weight loss on chronic disease risk and patient-reported outcomes in breast cancer survivors. Breast cancer survivors (stage I-III; body mass index 25–45 kg/m2) were randomized to a 12-month, remotely delivered (22 telephone calls, mailed material, optional text messages) weight loss (diet and physical acti...
Background
Text message-delivered interventions have potential to prevent weight regain and maintain diet and physical activity behaviours through extending contact with participants following initial weight loss, lifestyle interventions. Using the RE-AIM Framework, this study evaluated the adoption, reach, implementation, effectiveness, and mainte...

This paper examines the effects of the ACTIVATE Trial, a wearable-based physical activity intervention (Garmin Vivofit2® coupled with behavioral feedback, goal setting, and health coaching) on sleep outcomes.Methods
Post-primary treatment, inactive, po...
Background: Improving diet quality in chronic kidney disease (CKD) is challenging due to a myriad of competing recommendations. Patient-centered goal setting can facilitate dietary behavior change; however, its role in improving diet quality in CKD has not been investigated.
Aim: The aim of the study is to evaluate the effects of goal setting on im...
Importance:
Weight loss may be difficult for young women with obesity to achieve due to competing priorities (caring for children and/or full-time work), limiting their ability to engage in weight loss interventions. Older or postmenopausal women may also face challenges to weight loss such as caring responsibilities and menopause. Menopausal stat...
Abstract Background Healthy Living after Cancer (HLaC) was a national dissemination and implementation study of an evidence-based lifestyle intervention for cancer survivors. The program was imbedded into existing telephone cancer information and support services delivered by Australian state-based Cancer Councils (CC). We report here the reach, ef...
There is growing consensus around the limited attention given to documenting the process of intervention development, specifically the role of qualitative research. In this article, we seek to describe a missing piece of this process: how qualitative research, and related methodologies and theories, informs intervention development. We use our rese...
Background:
The ACTIVATE Trial examined the efficacy of a wearable-based intervention to increase physical activity and reduce sedentary behaviour in breast cancer survivors. This paper examines the effects of the intervention on health-related quality of life (HRQoL) and fatigue at 12 weeks (T2; end of intervention) and 24 weeks (T3; follow-up)....
Background
The benefits of an active lifestyle after a breast cancer diagnosis are well recognized, but the majority of survivors are insufficiently active. The ACTIVATE Trial examined the efficacy of an intervention (use of the Garmin Vivofit 2 activity monitor coupled with a behavioral feedback and goal‐setting session and 5 telephone‐delivered h...
Background
This brief report examines the maintenance of moderate to vigorous physical activity (MVPA) and sedentary behavior changes approximately 12 weeks after the delivery of the ACTIVATE Trial primary intervention (use of the Garmin Vivofit 2 activity tracker coupled with a behavioral feedback and goal‐setting session and 5 telephone‐delivered...
Cancer has become a global health concern with marked differences in the incidence and mortality rates between developing and developed countries. Understanding the factors hat shape uptake of preventative and screening services is key. We use in-depth interviews with 13 Zambian urban-based female cancer survivors to explore the facilitators and ba...
Breast cancer survivors often seek information about how lifestyle factors, such as diet, may influence their prognosis. Previous studies have reviewed evidence around single nutrients, individual foods or food groups. We reviewed studies examining relationships between overall dietary intake and prognosis in breast cancer survivors. A systematic s...
Background:
Extended contact interventions provide support for continued weight management (weight loss/prevention of weight regain) following a weight loss intervention. Text messages offer a medium for delivery in a potentially cost-effective, broad-reach manner.
Objectives:
This study aims to examine (i) the effectiveness of extended contact,...
Background:
Physical inactivity and sedentary behaviour are common amongst breast cancer survivors. These behaviours are associated with an increased risk of comorbidities such as heart disease, diabetes and other cancers. Commercially available, wearable activity trackers (WATs) have potential utility as behavioural interventions to increase phys...
Background:
Physical activity is positively associated with survival and quality of life among breast cancer survivors. Despite these benefits, the majority of breast cancer survivors are insufficiently active. The potential health benefits of reducing sedentary behaviour (sitting time) in this population have not been extensively investigated. Th...

Obesity is associated with poor prognosis and risk of treatment side-effects in breast cancer survivors. This pilot study assessed the feasibility, acceptability, safety and efficacy of a telephone-delivered weight loss intervention, among women (BMI 25-40 kg/m(2) ) following treatment for stage I-III breast cancer, on weight loss (primary ou...
Background: Obesity, physical inactivity and poor diet quality have been associated with increased risk of breast cancer-specific and all-cause mortality as well as treatment-related side-effects in breast cancer survivors. Weight loss intervention trials in breast cancer survivors have shown that weight loss is safe and achievable; however, few st...
Aim:
Dietary intake assessment is often difficult in research contexts because of time and resource constraints and participant burden. Valid, reliable and brief assessments of dietary behaviour are needed. Additionally, examination of instrument performance in a variety of populations is needed. This study assessed relative validity and responsiv...
Adiponectin is a beneficial adipocyte-secreted hormone, which circulates in a variety of multimeric forms termed low and high molecular weight (LMW/HMW). Effectiveness of clinical therapeutic trials which target adiponectin rely on accurate determination of circulating total and HMW adiponectin levels but the accuracy may be influenced by variation...
Aim:
Providing effective weight management services to the growing number of overweight or obese hospital patients necessitates long-term service provision; however, it is arguably not within the acute-care hospital remit to provide such extended services. Referral to community-based programs is required to provide continuing weight management ser...
Background
Given evidence shows physical activity, a healthful diet and weight management can improve cancer outcomes and reduce chronic disease risk, the major cancer organisations and health authorities have endorsed related guidelines for cancer survivors. Despite these, and a growing evidence base on effective lifestyle interventions, there is...

PURPOSE: Past-day recall, rather than recall of past week or a usual/typical day, may improve the validity of self-reported sedentary time measures. This study examined the test-retest reliability, criterion validity and responsiveness of the seven-item questionnaire, Past-day Adults' Sedentary Time (PAST). METHODS: Participants (n=90; breast cance...
Purpose:
There is no "gold standard" measure for moderate to vigorous physical activity (MVPA); some error is inherent to self-report and device-based measures. Few studies have examined agreement between self-report and device-based measures in the intervention trial context or whether the difference between measures is influenced by intervention...
Purpose
