AbstractCancer is increasing worldwide. Patterns of cancer are also changing. The evidence is summarised in the 2018 World Cancer Research Fund/American Institute for Cancer Research report Diet, Nutrition, Physical Activity and Cancer: a Global Perspective. The plasticity of cancer patterns implicates environmental factors as determinants of cancer, and nutrition influences key cellular and molecular processes that characterise cancer. Epidemiology identifies associations between aspects of diet, nutrition, and physical activity with one or more cancers; there is evidence for plausible mechanisms that imply that these are causal. Some nutritional exposures (alcohol and processed meat) are likely causal factors, but no singular factor protects against cancer (except dietary fibre for colorectal cancer). Cancer protection mainly derives from a systemic metabolic environment that promotes healthy cell replication and tissue integrity. Such a nutritional state reflects avoiding excess adiposity through healthy dietary patterns rich in plant foods (legumes, wholegrains, pulses, vegetables and fruits), with modest meat, fish and dairy, low in alcohol and salt preserved foods, and an active way of life, avoiding sedentary behaviours. Less is known about the impact of nutritional interventions in people with a diagnosis of cancer, but nutrition including adiposity and physical activity predict breast cancer outcome. Promoting healthy ways of life requires public information and education, but alone these do not generate change; a socio-political and cultural environment that is conducive to adopting healthy behaviours is needed. Uncertainties in the evidence offer promising directions for future research, but sufficient is known to act as a basis for public policy and clinical practice.

Abstract Background Early childhood educators (ECEs) play a critical role in promoting physical activity (PA) among preschoolers in childcare; thus, PA-related training for ECEs is essential. The Supporting PA in the Childcare Environment (SPACE) intervention incorporated: 1. shorter, more frequent outdoor play sessions; 2. provision of portable play equipment; and, PA training for ECEs. An extension of the SPACE intervention (the SPACE-Extension) incorporated only the shorter, more frequent outdoor play periods component of the original SPACE intervention. The purpose of this study was to explore the individual impact of these interventions on ECEs’ PA-related self-efficacy and knowledge. Methods ECEs from the SPACE (n = 83) and SPACE-Extension (n = 31) were administered surveys at all intervention time-points to assess: self-efficacy to engage preschoolers in PA (n = 6 items; scale 0 to 100); self-efficacy to implement the intervention (n = 6 items); and, knowledge of preschooler-specific PA and screen-viewing guidelines (n = 2 items). A linear mixed effects model was used to analyze the impact of each intervention on ECEs’ self-efficacy and knowledge and controlled for multiple comparison bias. Results The SPACE intervention significantly impacted ECEs’ self-efficacy to engage preschoolers in PA for 180 min/day (main effect), and when outdoor playtime was not an option (interaction effect). Further, the interaction model for ECEs’ knowledge of the total PA guideline for preschoolers approached significance when compared to the main effects model. Participants within the SPACE-Extension did not demonstrate any significant changes in self-efficacy or knowledge variables. Conclusions Findings from this study highlight the benefit of ECE training in PA with regard to fostering their PA-related self-efficacy and knowledge. Future research should explore the impact of PA training for ECEs uniquely in order to determine if this intervention component, alone, can produce meaningful changes in children’s PA behaviours at childcare.

Purpose The American Society of Clinical Oncology (ASCO) Cancer Research Committee designed a qualitative research project to assess the attitudes of cancer researchers and compliance officials regarding compliance with the US Privacy Rule and to identify potential strategies for eliminating perceived or real barriers to achieving compliance. Methods A team of three interviewers asked 27 individuals (13 investigators and 14 compliance officials) from 13 institutions to describe the anticipated approach of their institutions to Privacy Rule compliance in three hypothetical research studies. Results The interviews revealed that although researchers and compliance officials share the view that patients' cancer diagnoses should enjoy a high level of privacy protection, there are significant tensions between the two groups related to the proper standards for compliance necessary to protect patients. The disagreements are seen most clearly with regard to the appropriate definition of a “future research use” of protected health information in biospecimen and data repositories and the standards for a waiver of authorization for disclosure and use of such data. Conclusion ASCO believes that disagreements related to compliance and the resulting delays in certain projects and abandonment of others might be eased by additional institutional training programs and consultation on Privacy Rule issues during study design. ASCO also proposes the development of best practices documents to guide 1) creation of data repositories, 2) disclosure and use of data from such repositories, and 3) the design of survivorship and genetics studies.

Objective: This paper uses a qualitative approach to explore the factors that influence diet and physical activity choices of 11–13-year-olds with a particular focus on the impact of the school environment. Design: Qualitative focus groups. Setting: Three purposively sampled secondary schools in Devon, UK. Method: A total of 53 students, aged 11–13, took part in six focus groups. Thematic, framework analysis was used to analyse the data. Result: Four overarching themes emerged: (1) health now and in the future; (2) the role of others; (3) provision, temptation and addiction; and (4) boundaries, strategies and support. Participants demonstrated good knowledge of what constitutes a healthy lifestyle and its importance for future health, although it was not necessarily seen as a priority at this stage of life. Key influences on their choices were their peers and family, although participants also identified that the school environment influences the food choices they make while there. Conclusion: In this study, 11–13-year-olds identified that schools could do more to support them to make healthier food choices. However, future research needs to understand the constraints schools face in terms of food provision in order to highlight possible opportunities for intervention.

Abstract Purpose A healthy lifestyle after colorectal cancer (CRC) diagnosis may improve prognosis. Data related to lifestyle change in CRC survivors are inconsistent and potential interrelated changes are unknown. Methods We assessed dietary intake, physical activity, body mass index (BMI), waist circumference, and smoking among 1072 patients diagnosed with stages I–III CRC at diagnosis, 6 months and 2 years post-diagnosis. An overall lifestyle score was constructed based on the 2018 World Cancer Research Fund/American Institute of Cancer Research recommendations (range 0–7). We used linear mixed models to analyze changes in lifestyle over time. Results Participants had a mean (± SD) age of 65 ± 9 years and 43% had stage III disease. In the 2 years following CRC diagnosis, largest changes were noted for sugary drinks (− 45 g/day) and red and processed meat intake (− 62 g/week). BMI (+ 0.4 kg/m2), waist circumference (+ 2 cm), and dietary fiber intake (− 1 g/day) changed slightly. CRC survivors did not statistically significant change their mean intake of fruits and vegetables, alcohol, or ultra-processed foods nor did they change their physical activity or smoking behavior. Half of participants made simultaneous changes that resulted in improved concordance with one component as well as deteriorated concordance with another component of the lifestyle score. Overall lifestyle score changed from a mean 3.4 ± 0.9 at diagnosis to 3.5 ± 0.9 2 years post-diagnosis. Conclusions CRC survivors hardly improve their overall lifestyle after diagnosis. Implications for Cancer Survivors Given the importance of a healthy lifestyle, strategies to effectively support behavior changes in CRC survivors need to be identified.

The Impact

Purpose The current research contributes to the marketing literature by examining, and more importantly, better understanding a presentation format (i.e. PACE) in which caloric information is complemented with physical activity time required to offset consumption. The purpose of this paper is to systematically evaluate the impact of this approach in both actual and simulated consumption settings while providing evidence of its contribution to healthier decision-making. This research uncovered several important insights into how consumers are influenced by, and respond to, the presence of physical activity time. Design/methodology/approach The paper used experiential designs in five studies to examine how the presence of physical activity calorie equivalent (PACE) information affects consumption. The studies measured both intended and actual consumption behavior. The data were analyzed using analysis of variance as well as bootstrapping methods. Findings The paper establishes that PACE information reduces consumption compared to NLEA-mandated information. We show that the effectiveness of PACE information differs based on consumers’ level of health consciousness as well as food type. Our research also uncovers a moderating effect based on perceived difficulty of the featured activity. Finally, we show the psychological process underlying the effectiveness of PACE information. Research limitations/implications Future research can address the generalizability of current findings across different consumption domains and contexts. Our work focuses on the efficacy of information delivery at the point of consumption. The results of the current study may differ when the decision is being made at the point of purchase for future consumption. Practical implications The paper’s findings represent a win-win scenario for consumers and manufacturers alike. Manufactures stand to benefit from PACE information as many consumers are seeking healthier food options and are willing to pay a premium for items that help them make more healthful choices. Consumers will benefit as well, given the struggle with obesity and other diet-related ills, by being provided with a more effective means of making healthier choices. Social implications Obesity and diet-related chronic diseases are global pandemics affecting consumers throughout the world. This paper contributes to this issue by presenting manufacturers and researchers with a better understanding of how consumers can be encouraged to make healthier choices and overcome the barriers to healthier lifestyles. Originality/value This paper addresses a gap in the literature as well as an important social concern by better understanding how healthier nutrition choices can be encouraged.

International Experts

It has been estimated by various authorities that about one-third of cancers in Western high-income societies are attributable to factors relating to food, nutrition and physical activity. Identifying with confidence specific associations between dietary patterns, foods, body composition or individual nutrients is not simple because of the long latent period for cancer development, its complex pathogenesis and the challenge of characterising the multidimensional aspects of diet and activity over a lifetime. Reliable conclusions must therefore be drawn not only from randomised controlled trials but from a variety of methodological approaches, judged within a classic framework for inferring causality. Using a newly-developed method with a protocol for standardising the literature search and for analysis and display of the evidence, nine independent academic centres have conducted systematic reviews addressing the causal associations between food, nutrition and physical activity and risk of development of seventeen cancers, as well as of weight gain and obesity. A review has also examined the efficacy of such interventions in subjects with cancer. The reviews have been assessed by an independent Panel of twenty-one international experts who drew conclusions with grades of confidence in the causality of associations and made recommendations. Recommendations are given as public health goals as well as for individuals.

The Impact

Physical inactivity has been shown to increase the risk for several chronic diseases across the lifespan. However, the impact of physical activity and aerobic fitness on childhood cognitive and brain health has only recently gained attention. The purposes of this article are to: 1) highlight the recent emphasis for increasing physical activity and aerobic fitness in children’s lives for cognitive and brain health; 2) present aspects of brain development and cognitive function that are susceptible to physical activity intervention; 3) review neuroimaging studies examining the cross-sectional and experimental relationships between aerobic fitness and executive control function; and 4) make recommendations for future research. Given that the human brain is not fully developed until the third decade of life, preadolescence is characterized by changes in brain structure and function underlying aspects of cognition including executive control and relational memory. Achieving adequate physical activity and maintaining aerobic fitness in childhood may be a critical guideline to follow for physical as well as cognitive and brain health.

The Impact

Purpose. Transitioning from high school to college generally results in reduced physical activity and weight gain at a rate that is higher than the general population. The purpose of this study was to examine the effects of three progressively higher step recommendations over 24 weeks on changes in body weight and body composition. Methods. Ninety-two freshmen college women wore a multifunction pedometer for 24 weeks after being randomly assigned to a daily step level: 10,000, 12,500, or 15,000. Pedometer data were downloaded every two weeks and participants were counseled on meeting their step recommendation. Body weight and body composition were assessed at baseline and 24 weeks. Body composition was assessed by dual X-ray absorptiometry. Results. On average, women took 10,786 ± 1501, 12,650 ± 2001, and 13,762 ± 2098 steps per day for the 10,000-, 12,500-, and 15,000-step groups, respectively (F = 15.48, P<0.0001). Participants gained 1.4 ± 2.6, 1.8 ± 2.1, and 1.4 ± 2.1 kg for the 10,000-, 12,500-, and 15,000-step groups, respectively (F = 37.74, P<0.0001). Weight gain was not significantly different between groups (F = 0.18, P=0.8385). There was also no difference in fat weight gain (F = 0.41, P=0.7954). Discussion. A step recommendation beyond 10,000 does not prevent weight or fat gain over the first year of college. Future research should focus on either intensity of physical activity or the addition of dietary interventions to prevent weight gain during the first year of college.
