RESUMO

Introduction: The Government of Thailand has drafted legislation to protect children from the harmful impact of unhealthy food (including beverages) marketing. Local evidence on Thai children's exposure to, and the impact of, this marketing is necessary to, first, support the adoption of this Law and, second, to contribute to assessing policy implementation and effectiveness. This study aimed to develop and validate a questionnaire for examining Thai children's exposure to unhealthy food marketing and its impact on diet-related outcomes. Materials and methods: To design the questionnaire, we first conceptualised the range of impacts of unhealthy food marketing on children's diet-related outcomes based on published frameworks. These outcomes related to food brand loyalty, preference, purchase and consumption. We conducted a literature review to gather related questions used in earlier surveys to assess these outcomes. Using these questions, we assessed content validity with five experts. Face validity and reliability were assessed for 32 children. Validity was assessed using Content Validity Index (CVI) and Kappa statistics. Reliability was assessed using Cronbach's alpha and intraclass correlation coefficients (ICC). Results: We identified 15 survey questions that had been used to assess the outcomes of interest. The CVI of all questions was 1.0, indicating perfect agreement with each question's relevance by the experts. Most questions were perceived to be easy to read and comprehend, suggesting face validity. Cronbach's alpha and ICC of all questions were both 0.75, demonstrating internal consistency across responses to questions about, separately, brand loyalty, preferences, purchase and consumption. Conclusion: The final 15-item questionnaire provides a valid and reliable survey instrument for measuring the impact of unhealthy food marketing on children's diet-related outcomes. This instrument will be useful for gathering local evidence on the need for policy reform to protect children from unhealthy food marketing in Thailand. The instrument also provides a cost-effective approach for generating evidence in other jurisdictions to propel policy actions. This is a pilot study and the validity and reliability needs further testing after a larger-scale roll-out.

RESUMO

Unhealthy food and non-alcoholic beverage marketing (UFM) adversely impacts children's selection and intake of foods and beverages, undermining parents' efforts to promote healthy eating. Parents' support for restrictions on children's exposure to food marketing can catalyse government action, yet research describing parent concerns is limited for media other than television. We examined parents' perceptions of UFM and their views on potential policies to address UFM in supermarkets and on digital devices - two settings where children are highly exposed to UFM and where little recent research exists. We conducted in-depth interviews with sixteen parents of children aged 7-12 from Victoria, Australia, analysing the data thematically. Parents perceived UFM as ubiquitous and viewed exposure as having an immediate but temporary impact on children's food desires and pestering behaviours. Parents were concerned about UFM in supermarkets as they viewed it as leading their children to pester them to buy marketed products, undermining their efforts to instil healthy eating behaviours. Parents generally accepted UFM as an aspect of contemporary parenting. Concern for digital UFM was lower compared to supermarkets as it was not directly linked to pestering and parents had limited awareness of what their children saw online. Nevertheless, parents felt strongly that companies should not be allowed to target their children with UFM online and supported government intervention to protect their children. While parents supported government policy actions for healthier supermarket environments, their views towards restricting UFM in supermarkets varied as some parents felt it was their responsibility to mitigate supermarket marketing. These findings could be used to advocate for policy action in this area.

RESUMO

Nutrition labeling on the front of food packages can support more healthful purchase decisions and encourage favorable reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise the evidence on the effectiveness of front-of-pack labeling (FOPL) on diet-related outcomes and food reformulation to inform policy recommendations. The search was conducted on 11 academic and gray literature databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation), vote counting, and meta-analyses, where appropriate. Overall, 221 articles were included in the review. The randomized controlled trial evidence suggested that, compared with when no FOPL was present, FOPL likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty of evidence), and the healthfulness of food choices (moderate certainty) and purchases (moderate certainty). Interpretive FOPL had a greater effect on these outcomes compared with noninterpretive systems (moderate certainty). There was inconsistency in the best-performing interpretive FOPL system.

RESUMO

Nutrition labeling supports healthier diets by aiding purchase decisions and stimulating reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise evidence on the effectiveness of nutrient declarations and nutrition and health claims on diet-related outcomes. The search spanned 11 academic databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) and vote counting. Data were available from 170 studies. Randomized controlled trials (RCTs) suggest that nutrient declarations likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty) and may improve the healthfulness of choices (low certainty) versus no label. RCT evidence also suggests that claims likely increased consumer perceptions of food healthfulness and increased choice and purchases of labeled foods (both moderate certainty), irrespective of nutritional quality. To improve label understanding and avoid misinterpretation, nutrient declarations may incorporate interpretive elements and claims can apply disqualifying conditions for their usage, on the basis of overall nutritional quality.

RESUMO

OBJECTIVES: In 2021, the US Congress passed the Accelerating Access to Critical Therapies for Amyotrophic Lateral Sclerosis Act. The law encourages development of "tools, methods, and processes" to improve clinical trial efficiency for neurodegenerative diseases. The Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) is an outcome measure administered during in-person clinic visits and used to support investigational studies for persons living with amyotrophic lateral sclerosis. Availability of a standardized, remote-use version of the ALSFRS-R may promote more inclusive, decentralized clinical trials. A scoping literature review was conducted to identify existing remote-use ALSFRS-R tools, synthesize feasibility and comparability of administration modes, and summarize barriers and facilitators to inform development of a standardized remote-use ALSFRS-R tool. METHODS: Included studies reported comparisons between remote and in-person, clinician-reported, ALSFRS-R administration and were published in English (2002-2022). References were identified by searching peer-reviewed and gray literature. Twelve studies met the inclusion criteria and were analyzed to compare findings within and across modes of administration. RESULTS: Remote modes of ALSFRS-R administration were categorized into 4 nonmutually exclusive categories: telephone (n = 6), videoconferencing (n = 3), computer or online platforms (n = 3), mobile applications and wearables (n = 2), and 1 unspecified telemedicine modality (n = 1). Studies comparing in-person to telephone or videoconferencing administration reported high ALSFRS-R rating correlations and nonsignificant between-mode differences. CONCLUSIONS: There is insufficient information in the ALSFRS-R literature to support remote clinician administration for collecting high quality data. Future research should engage persons living with amyotrophic lateral sclerosis, care partners, and providers to develop a standardized remote-use ALSFRS-R version.

RESUMO

Food and nonalcoholic beverage marketing is implicated in poor diet and obesity in children. The rapid growth and proliferation of digital marketing has resulted in dramatic changes to advertising practices and children's exposure. The constantly evolving and data-driven nature of digital food marketing presents substantial challenges for researchers seeking to quantify the impact on children and for policymakers tasked with designing and implementing restrictive policies. We outline the latest evidence on children's experience of the contemporary digital food marketing ecosystem, conceptual frameworks guiding digital food marketing research, the impact of digital food marketing on dietary outcomes, and the methods used to determine impact, and we consider the key research and policy challenges and priorities for the field. Recent methodological and policy developments represent opportunities to apply novel and innovative solutions to address this complex issue, which could drive meaningful improvements in children's dietary health.

RESUMO

Traditionally considered a disease common in the older population, colorectal cancer is increasing in incidence among younger demographics. Evidence suggests that populational- and generational-level shifts in the composition of the human gut microbiome may be tied to the recent trends in gastrointestinal carcinogenesis. This review provides an overview of current research and putative mechanisms behind the rising incidence of colorectal cancer in the younger population, with insight into future interventions that may prevent or reverse the rate of early-onset colorectal carcinoma.

RESUMO

BACKGROUND: Food marketing is a key factor that influences children's dietary behaviors. This study assessed the nature and extent of food and beverage advertising on television (TV) in 2014 and 2022 in Thailand. METHODS: TV was recorded for one week in March 2014 and in May 2022 from 7-9am and 3-7 pm on weekends, and 3-7 pm on weekdays across two channels (64 h recorded each year). The nutrient profile model from Bureau of Nutrition, Ministry of Public Health Thailand was used to classify food and non-alcoholic beverages as: Group A ('healthy'), Group B ('less unhealthy') or Group C ('unhealthy'). RESULTS: In 2014, 475 food advertisements were identified, with on average of 6.3 unhealthy food advertisements per hour. In 2022, 659 food advertisements were identified, with an average of 9.2 unhealthy food advertisement per hour. In both time periods, the most frequently advertised food products were non-alcoholic beverages. The rate of unhealthy food advertising per hour of broadcast was significantly higher than for other moderately unhealthy and healthy foods, and was also significantly higher in 2022 than in 2014. CONCLUSIONS: Food and beverage advertising on Thai television is predominantly promotes unhealthy foods and, in particular, sugar-sweetened beverages. Therefore, Thai Government should enact new legislation to protect children from food TV ads in order to control both the frequency and nature of unhealthy TV food marketing to protect the health of Thai children.

RESUMO

Many cultures share common constellations and common narratives about the stars in the night sky. Previous research has shown that this overlap in asterisms, minimal star groupings inside constellations, is clearly present across 27 distinct culture groups and can be explained in part by properties of individual stars (brightness) and properties of pairs of stars (proximity) (Kemp, Hamacher, Little, & Cropper, 2022). The same work, however, found no evidence that properties of triples (angle) and quadruples (good continuation) predicted constellation formation. We developed a behavioral experiment to explore how individuals form constellations under conditions that reduce cultural learning. We found that participants independently selected and connected similar stars, and that their responses were predicted by two properties of triples (angle and even spacing) in addition to the properties of brightness and proximity supported by previous work. Our findings lend further evidence to the theory that commonality of constellations across cultures is not a result of shared human history but rather stems from shared human nature.

RESUMO

INTRODUCTION: In 2020, Google took voluntary action to restrict food and beverage advertising through its online channels in the European Union/United Kingdom using Google's own nutrient profiling model to identify products eligible to be marketed to children through its Google Display Network. The objective of this study was to evaluate the potential impact of the Google policy, if applied to the U.S. market, on restricting online advertising of the top-selling packaged foods and beverages in the U.S. METHODS: The top 25 U.S. food and beverage manufacturers were identified. Nutrient data for products from these manufacturers were sourced from Label Insight (a Nielsen IQ company) in 2021. Each product was examined against four nutrient profiling models: the Google nutrient profiling model, the WHO Europe nutrient profiling model, the Pan American Health Organization nutrient profiling model, and the Chilean government nutrient profiling model. RESULTS: Under Google's nutrient profiling model, 18% of 14,188 products were eligible to be advertised to children, representing $44 billion in revenue for the top 25 U.S. manufacturers of the >$240 billion generated annually. The Google nutrient profiling model permitted the most products to be advertised to children of all four nutrient profiling models examined. CONCLUSIONS: U.S. children engage extensively with online media. In place of government regulation, the Google advertising policy and related nutrient profiling model would limit online advertising of the most unhealthful products to children, if the policy were to be applied to the U.S. market. The effectiveness of the policy would be strengthened by refining the Google nutrient profiling model to better align with nutrient profiling models developed by authoritative health agencies, including the WHO.

RESUMO

OBJECTIVE: Children's exposure to unhealthy food marketing contributes to poor diets by influencing the foods that children like, request, buy and consume. This study aimed to use confirmatory mediational analyses to test a hypothetical model of marketing effects, to better understand the mechanisms behind food marketing's impacts on children. DESIGN: Children responded to a cross-sectional online survey about their attitudes towards, and purchase and consumption behaviours of, ten frequently promoted food/beverage brands and their media use. Structural equation modelling tested a priori potential pathways for the effects of food marketing exposure on children's diets. PARTICIPANTS: 10-16-year-old children (n 400). SETTING: Australia. RESULTS: There was a significant positive correlation between children's commercial screen media use and their attitudes towards brands (related to perceived social norms) and their brand purchasing behaviours, including their own purchases and requests to parents. The use of strategies to avoid advertising in commercial screen media reduced but did not remove the association between media use and brand purchases. Other brand exposures (on clothing, outdoor advertising, sponsorships) had a positive association with children's perceived social norms about brands and their brand purchases and requests. Non-commercial screen media use was not associated with any brand-related outcomes. CONCLUSIONS: Commercial screen media use and other brand exposures were strongly positively associated with children's perceptions and purchasing behaviours of frequently marketed food/beverages. Regulations to restrict children's exposures to food marketing on-screen and through other media are required to reduce the effect of marketing exposure on children's food purchasing behaviours.

RESUMO

BACKGROUND: This systematic review examined the effectiveness of experiential learning interventions for improving children's physical activity knowledge, attitudes, and behaviours. It also aimed to identify intervention characteristics that resulted in the greatest impact. METHODS: Four databases: Education Research Complete, Scopus, Web of Science and PsychINFO were searched from database inception to January 2023. Eligible studies: (1) included children 0-12 years; (2) assessed the effect of physical activity outcomes on children's physical activity knowledge, attitudes or behaviour and (3) were randomised controlled trials conducted in any setting. Study risk of bias was assessed by two independent reviewers using the Cochrane risk of bias tool. Intervention approaches were categorised, and effect sizes were compared across studies for each outcome. RESULTS: Twelve studies were included in the review: ten in school age and two in below five years. For behavioural outcomes, six of eight studies showed medium to large effects (effects size (ES) range: 0.3-0.9), two of the three studies that assessed attitudinal outcomes displayed medium effects (ES range: 0.4-0.5) and both studies that assessed knowledge outcomes displayed medium to large effects (ES range: 0.4-1.3). The two experiential learning interventions among children < 5 years demonstrated small to medium effects on behaviour change (ES range: 0.2-0.5). Effective interventions combined enjoyable practical activities (fitness activities, games and challenges), with behaviour change techniques (goal setting, and self-monitoring), were underpinned by a behaviour change theory, and were often of short duration (< 4 months) but intense (several sessions/week). Moderate to high statistical heterogeneity was observed for behaviour outcomes and risk of bias across studies was generally high. CONCLUSIONS: This review provides some evidence supporting the effectiveness of experiential learning interventions in improving physical activity outcomes in school-aged children. Additional evidence is needed in children <5 years old. Future experiential learning interventions need to strengthen the evidence with rigorous methodological quality and clear reporting of the experiential learning components.

RESUMO

The Microbiology Society Education and Outreach Network (EON) recently hosted the Teaching Symposium at the Microbiology Society Annual Conference, sponsored by Access Microbiology. The presence of the Symposium as an established parallel session within the wider Annual Conference reflects the importance of high-quality, contemporary microbiology education and outreach delivered in an enthusiastic and inclusive manner. At the 2023 Symposium, a variety of pedagogical research projects in higher education learning, teaching and assessment, as well as public engagement projects, were showcased through invited talks, offered talks, flash talks and posters. The event was attended by up to 70 delegates. Several themes were noted throughout the day: engaging with Gen Z (Generation Z, those born between 1996 and 2010), active learning, art in science and engaging with non-higher education (HE) audiences. Inclusivity was a key driver in the organization of the Symposium; the room was set up to encourage discussion and participants could ask questions using an online platform as well as speaking in the room. We now encourage all speakers to consider publishing their work as a peer-reviewed article for further dissemination and impact.

RESUMO

Background: The ubiquitous nature of food marketing on digital media likely has a profound effect on children's food preferences and intake. Monitoring children's exposure to digital marketing is necessary to raise awareness of the issue, inform policy development, and evaluate policy implementation and effect. Objectives: This study aimed to establish whether smaller time samples (less time and/or fewer days captured) would provide robust estimates of children's usual exposures to food marketing. Methods: Using an existing data set of children's digital marketing exposures, which captured children's total screen use over 3 d, a reliability assessment was performed. Results: A subsample of 30% of children's usual screen time was found to provide reliable estimates of digital food marketing exposure compared with the full sample (intraclass correlation coefficient: 0.885; Cronbach α: 0.884). There was no difference in the rates of marketing (exposures/h) between weekdays and weekend days. Conclusions: These findings enable researchers to reduce the time and resource constraints that have previously restricted this type of monitoring research. The reduced media time sample will further lessen participant burden.

RESUMO

INTRODUCTION: Over the last decade, a paradigm shift has been made in treating pancreatic cancer. Starting in 2011, several trials demonstrated a survival advantage for multiagent chemotherapy (MAC). However, the implication for survival at the population level remains unclear. METHODS: A retrospective study of the National Cancer Database from 2006 to 2019 was conducted. Patients treated from 2006 to 2010 were classified as "Era 1", and those treated from 2011 to 2019 as "Era 2." RESULTS: A total of 316,393 patients with pancreatic adenocarcinoma were identified, with 87,742 treated in Era 1 and 228,651 in Era 2. Survival increased from Era 1 to Era 2 in all patients and sub-analyses; surgical (18.7 vs 24.6 months, HR .85, 95% CI 0.82-.88, P < .001), imminently resectable (Stage IA and IB, 12.2 vs 14.8 months, HR .90, 95% CI 0.86-.95, P < .001), high-risk (Stage IIA, IIB, and III, 9.6 vs 11.6 months, HR .82, 95% CI 0.79-.85, P < .001), and Stage IV (3.5 vs 3.9 months, HR .86, 95% CI 0.84-.89, P < .001). Survival was decreased for those who were African American (P = .031), on Medicaid (P < .001), or in the lowest quartile of annual income (P < .001). Surgery rates decreased from 20.5% in Era 1 to 19.8% in Era 2 (P < .001). DISCUSSION: Adoption of MAC regimens at a population level correlates with improved pancreatic cancer survival. Unfortunately, socioeconomic factors are associated with an unequal benefit from new treatment regimens, and underuse of surgery for resectable neoplasms persists.

RESUMO

PURPOSE OF REVIEW: Protecting children from unhealthful food marketing is a global priority policy for improving population diets. Monitoring the nature and extent of children's exposure to this marketing is critical in policy development and implementation. This review summarises contemporary approaches to monitor the nature and extent of food marketing to support policy reform. RECENT FINDINGS: Monitoring approaches vary depending on the stage of progress of related policy implementation, with resource implications and opportunity costs. Considerations include priority media/settings. marketing techniques assessed, approach to classifying foods, study design and if exposure assessments are based on media content analyses or are estimated or observed based on children's media use. Current evidence is largely limited to high-income countries and focuses on content analyses of TV advertising. Ongoing efforts are needed to support monitoring in low-resource settings and to progress monitoring to better capture children's actual exposures across media and settings.

RESUMO

BACKGROUND: Retention of the nipple-areola complex with nipple-sparing mastectomy (NSM) techniques provides a more natural cosmetic result than procedures that sacrifice the nipple. While the oncologic safety of NSM is established by several studies, there is little long-term data on outcomes in BRCA mutation carriers with breast cancer. PATIENTS AND METHODS: BRCA1/2 mutation carriers who underwent NSM and immediate reconstruction from 2008 to 2019 were reviewed and patients with breast cancer on biopsy or final pathology were included. Patient demographics and tumor characteristics, as well as treatment, recurrence, and survival data were collected. RESULTS: A total of 114 therapeutic NSM were performed in 105 BRCA mutation carriers (56 BRCA1, 47 BRCA2, and two women with both mutations). Median age was 45 years. Cancers were 18% stage 0, 52% stage I, 27% stage II, and 3% stage III. Mean invasive tumor size was 1.6 cm and 33 (35%) invasive tumors were triple negative. There were five (4.4%) positive nipple margins on final pathology; all underwent nipple excision. Most patients (80, 76%) received systemic therapy: 65 (62%) received chemotherapy and 48 (46%) received endocrine therapy. At 70 months median follow-up (range 15-150 months), no patient had developed a recurrence in the retained nipple-areola complex or at the site of a nipple excised for a positive margin. The rate of locoregional recurrence outside the nipple was 2.6%, and the rate of distant recurrence was 3.8%. Overall survival was 96%. CONCLUSIONS: NSM is a safe option for BRCA1 and BRCA2 mutation carriers who undergo mastectomy for breast cancer.
