Aim: Picky eating is a common appetitive trait reported among children and adolescents and may have detrimental effects on their weight, vegetable, and fruit intake, impacting health status. However, an updated systematic review of the literature and summary of effect estimates is required. This study aims to explore the association between picky eating with weight, vegetable and fruit intake, vegetable-only intake, and fruit-only intake. Methods: A systematic literature search of six electronic scientific databases and data extraction was performed between November 2022 and June 2023. Original articles that examined picky eating in association with weight, vegetable and/or fruit intake were included. PRISMA guidelines were followed and meta-analytical and meta-regression analyses were conducted to compute summary effect estimates and explore potential moderators. PROSPERO registration: CRD42022333043. Results: The systematic review included 59 studies of which 45 studies were included in the meta-analysis. Overall, the summarized effect estimates indicated that picky eating was inversely associated with weight [Cohen's d z : -0.27, 95% confidence interval (CI): -0.41 to -0.14, p < 0.0001]; vegetable and fruit intakes (Cohen's d z : -0.35, 95% CI: -0.45, -0.25, p < 0.0001); vegetable-only intake (Cohen's d z : -0.41, 95% CI: -0.56, -0.26, p < 0.0001), and fruit-only intake (Cohen's d z : -0.32, 95% CI: -0.45, -0.20, p < 0.0001). Picky eating was positively associated with underweight (Cohen's d z : 0.46, 95% CI: 0.20, 0.71 p = 0.0008). Conclusion: Although effect sizes were small, picky eating was inversely associated with weight, vegetable, and fruit intakes, and positively associated with underweight in children and adolescents aged birth to 17 years.

Purpose: Nutrition plays an important role in cancer survivorship. This systematic review and meta-analysis aim to critically assess and quantify the effectiveness of nutrition care interventions provided by dietitians to survivors who have completed treatment for cancer., Methods: A systematic review of randomized controlled trials (RCTs) published from January 2004 to November 2023 reporting the effectiveness of primary care dietetic interventions with adult cancer survivors was conducted. PubMed, Scopus, CINAHL, Embase, ProQuest and PsycINFO databases were searched for key terms. Meta-analyses were conducted where there were sufficient studies of the same cancer type and outcomes., Results: Twelve RCTs representing 1138 cancer survivors (519 breast cancer; 75 prostate cancer; 544 colorectal cancer) were included. Primary outcome measures included weight loss (n = 6), quality of life (n = 2), reducing lymphedema-related arm volume (n = 2), nutritional status (n = 1) and increasing fruit and vegetable intake (n = 1). Weight loss was observed in studies where this was the primary outcome. Results for quality of life varied. Meta-analyses of RCTs with breast cancer survivors showed that dietitian intervention achieved a mean of 3.7 kg greater intentional weight loss and 2.3% greater body fat decrease than control (p < 0.0001)., Conclusions: This study provides evidence for the effectiveness of primary care dietetic interventions by dietitians with cancer survivors, particularly with respect to intentional weight and fat loss in breast cancer survivors., Implications for Cancer Survivors: Dietitians can play a key role in managing weight and improving long term health outcomes and prognosis for cancer survivors beyond the acute care setting., (© 2024.

Aim: Dietitians work in high-pressure environments and student dietitians attend placement in these settings. Resilience is a personal quality that can buffer against the stressors of professional placement; however, little is known about how dietetics students learn resilience. This study aimed to describe how resilience is embedded within Australian and New Zealand dietetics curricula., Methods: This three-phased qualitative study examined 18 credentialed dietetics education programs in Australia (n = 16) and New Zealand (n = 2). In Phase 1 (document analysis), publicly available curricular documents were screened for key resilience terms. In Phase 2, academics were invited to participate in a semi-structured interview on Microsoft Teams to verify and advance upon documentary evidence. Extracted data were combined and evaluated according to Bloom's Taxonomy in Phase 3., Results: Fifty-six courses were found to have documented mentions of resilience factors from dietetics programs in Australia and New Zealand. Academics from 14 universities (12 Australia and 2 New Zealand) were interviewed. Three themes were identified from Phase 3: Resilience is valuable content within a dietetics degree, Resilience can be taught indirectly throughout programs and Resilience education is not static. Resilience education was mostly taught by academic dietitians in courses prior to placement and assessed by students completing self-reflection while on placement. The documentation of resilience within learning objectives and graduate attributes varied between universities., Conclusion: While all dietetics programs included some resilience curricula, academics acknowledged that resilience content and their own knowledge base could be strengthened. The findings provide direction for program improvements and further research., (© 2023 The Authors.

Background: The Australian 2021 Royal Commission identified that the dietetic workforce needs to grow in size and capacity to support nutrition care in older adults. However, little is known about dietitians' knowledge, skills and attitudes (KSA) regarding working with older adults in residential aged care facilities (RACFs) or their homes. This review describes dietitians' KSA regarding older adults in RACFs and home care services., Methods: A systematic literature search was conducted in August 2021 to identify studies examining any aspect of dietitians or student dietitians' KSA working in RACFs and home care services. No restrictions were applied to methodological design, language, location or publication year. Studies were assessed for quality using the Johanna Briggs Institute Quality Appraisal Tools. Study findings were analysed thematically using meta-synthesis., Results: All 17 studies that met the inclusion criteria explored dietitians' attitudes towards their role, three studies examined perceived knowledge, although no studies objectively explored dietitians' skill levels. Five themes were developed inductively: (1) recognising their contribution as dietitians; (2) lacking clarity about the boundaries of their role; (3) all team members have a role to play in nutrition care; (4) assumptions and biases about working with older people; and (5) needing to build capacity in the workforce., Discussion: Dietitians have mixed attitudes about working in RACFs and home care services. Future directions include evaluating dietitians' role in RACFs, reviewing education and training and practical opportunities for student dietitians, and assessing the impact of more dietitian support on an older person's dietary intake and nutrition., (© 2022 The Authors.

Type 2 diabetes (T2D) is a major public health concern. Optimal management of T2D often requires individuals to make substantial changes to their dietary intake. This research employed a qualitative methodology to examine decision making processes underpinning dietary behaviour change. Semi-structured telephone interviews were conducted on a purposive sample of 21 Australian adults who had recently consulted a dietitian after being diagnosed with T2D. Data were analysed using theoretical thematic analysis and themes were matched deductively with constructs that underpin motivational, volitional, and implicit processes which exist in common models of behaviour change. Influences on motivation, such as a desire to improve health status and making use of valuable support networks featured in participant narratives. Volitional influences included knowing their limits, dealing with falling off the wagon, and learning how their body responds to food. The themes unlearning habits and limit the availability were identified as underpinning implicit influences on dietary change. Individual differences and emotions were constructs additional to the model that influenced dietary change. These findings contribute to a richer understanding of the subjective experiences of adults with T2D regarding dietary change and highlight the multiple processes that guide their decision making in this context., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Rigby et al.

Aim: The application of behaviour change science is fundamental to the role of dietitians. This study aimed to describe how behaviour change science is embedded within the curricula of accredited/registered dietetics programs in Australia and New Zealand., Methods: A descriptive study triangulated quantitative document analysis of curricula content from university websites (Part 1) with qualitative, structured interviews with dietetics academics (Part 2). Part 2 verified and advanced upon information captured in Part 1 and was analysed using thematic content analysis., Results: Twenty-five courses from 18 university programs (15 Australia and 3 New Zealand) were synthesised. Fifteen interviews (12 Australia, 3 New Zealand) were conducted. Behaviour change science was taught and assessed at varying levels across all programs. It was taught primarily within lectures or workshops where students apply skills learnt in practical case-based activities, and assessed through small group education planning or demonstrating communication and counselling skills. Five themes were identified from the interviews: (1) behaviour change science should be foundational; (2) integrate and scaffold within curricula; (3) structural limitations within curricula; (4) challenging for students and (5) recommendations for competencies., Conclusion: Behaviour change science is clearly of value to the dietetics profession. Core content appears to be embedded across all university programs; however, the level and depth of the content varied. The knowledge gained from this study provides direction for curricular improvements., (© 2021 The Authors.

Objective: We aimed to explore both the dietary-related behavior change techniques (BCTs) adults with type 2 diabetes (T2D) described to enact themselves and the BCTs they perceived their dietitians to enact within consultations., Design: Qualitative study involving semistructured telephone interviews with adults who consulted with a dietitian after their T2D diagnosis. Participants shared their experience of dietary behavior change and interactions with dietitians., Setting: Telephone-based interviews from an Australian university setting., Participants: Twenty-one adults (12 females and 9 males) aged 36-75 years were self-selected and invited by email., Phenomenon of Interest: Dietary behavior changes reportedly enacted after a T2D diagnosis by participants and their dietitians., Analysis: Transcripts were analyzed through thematic content analysis according to the BCT taxonomy., Results: Participants described several BCTs such as problem-solving and self-monitoring (behavior), which helped their dietary behavior change. Participants perceived their dietitians to use BCTs, including goal setting (outcome), self-monitoring (behavior), and instruction on how to perform the behavior. These participants who had consulted with a dietitian reported additional techniques than those prescribed in the consultation process., Conclusions and Implications: Adults with T2D undertake a variety of BCTs to support dietary behavior change. Dietitians can draw on behavior change taxonomies to support behavior change in clients., (Copyright © 2022 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

Background: Behavior change theories frameworks provide the theoretical underpinning for effective health care. The extent to which they are applied in contemporary dietetics interventions has not been explored., Objective: To systematically review the evidence of behavior change theory-based interventions delivered by credentialed nutrition and dietetics practitioners in primary health care settings., Methods: Medline, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Embase, and Cochrane databases were searched for English language, randomized controlled trials before August 2019. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. Eligible interventions included adults (aged ≥18 years) receiving face-to-face dietetics care underpinned by behavior change theories in primary health care settings with outcome measures targeting changes in health behaviors or health outcomes. Screening was conducted independently in duplicate and data were extracted using predefined categories. The quality of each study was assessed using the Cochrane Risk of Bias tool. The body of evidence was assessed using the Academy of Nutrition and Dietetics Evidence Analysis Manual Conclusion Grading Table., Results: Thirty articles reporting on 19 randomized controlled trials met the eligibility criteria, representing 5,172 adults. Thirteen studies (68%) showed significant improvements for the primary outcome measured. Social cognitive theory was the behavior change theory most commonly applied in interventions (n=15) with 11 finding significant intervention effects. Goal setting, problem solving, social support, and self-monitoring were the most commonly reported techniques (n=15, n=14, n=11, and n=11, respectively). Most studies had a high (n=11) or unclear (n=8) risk of bias. There was fair evidence (Grade II) supporting the use of behavior change theories to inform development of dietetics interventions., Conclusions: Interventions delivered by credentialed nutrition and dietetics practitioners that were underpinned by behavior change theories and utilizing various behavior change techniques were found to have potential to be more effective at improving patient health outcomes than dietary interventions without theoretical underpinnings. Findings from this review should inform future primary health care research in the area of dietary behavior change. In addition, findings from this review highlight the need for stronger documentation of use of behavior change theory and techniques that map on to the theory within dietetics practice., (Copyright © 2020 Academy of Nutrition and Dietetics.

Low and middle-income countries are experiencing the dual burden of malnutrition which is, at least in part, attributable to changes in eating behaviours of children under age five. Development of food choices is influenced by multiple factors and understanding the interplay of these factors in early childhood in these countries is necessary to promote healthy food choices. We conducted a systematic review to examine the evidence of family and community factors targeted in interventions to influence the eating behaviour of preschool-aged children in low and middle-income countries. A search for peer-reviewed papers was conducted using CINAHL, MEDLINE, PsycINFO, Scopus and ProQuest Health Management published prior to September 2018, in English language including preschool-aged children (PROSPERO registration CRD42018108474). Fourteen studies published between 1994 and 2017 were eligible for inclusion. Factors that were consistently and positively associated with children's healthy food consumption were household food availability, nutritional knowledge of family or caregivers and family income. Unhealthy food consumption in children was inversely associated with family or caregivers' nutritional knowledge. Children's micronutrient intake was positively associated with household food availability, nutritional knowledge of family or caregivers and food availability within the surrounding environment. Findings highlight the importance of targeting nutritional knowledge of family or caregivers to facilitate healthy eating behaviours in children. In addition, creating a supportive family environment via increasing household food availability and family income should be considered when designing interventions to promote healthy eating behaviours in preschool-aged children living in low and middle-income countries., (Copyright © 2019 Elsevier Inc.
