RESUMO

Dietary intake is known to impact athletic performance. The factors that influence dietary intake have been investigated widely, but their collective effect has not been examined. The primary aim of this cross-sectional study was to assess the relationship between dietary intake and nutrition knowledge, body image, weight control, macronutrient balance, and hedonic hunger. Forty-two student athletes or active individuals were recruited through contact with sporting organisations and course coordinators, advertising via twitter, and flyers posted within university buildings. Nutrition knowledge, body image, weight control, macronutrient balance, and hedonic hunger were measured using the Abridged Nutrition for Sport Knowledge Questionnaire, Body Image Disturbance Questionnaire and Contour Drawing Rating Scale, a Weight Fluctuation Measure, Australian Eating Score, and Power of Food Scale, respectively. Hierarchical regression analysis, correlation testing, and mean difference testing were applied. Carbohydrate intake, body image disturbance scores, weight fluctuation, and hedonic hunger for food tasted had a significant relationship (R2 = 64.6%, Adj R2 = 0.608%, p < 0.001) with dietary energy intake. Student athletes' dietary intakes are influenced by multiple potentially modifiable factors. Future studies should use larger sample sizes, with interventions focusing on individual modifiable factors to determine how dietary intake can be most significantly impacted.

RESUMO

OBJECTIVES: Injury/poor health is an important barrier to women's participation in sport and physical activity. This study aimed to identify perceived challenges sport programme deliverers face when supporting physically inactive women to prevent/manage injury. METHODS: Sport programme deliverers, targeting physically inactive women in Victoria, participated in concept mapping to brainstorm, sort and rate (impact on their ability to prevent/manage injury, frequency of and difficulty to overcome the challenge on a 1 (low)-5 (high) scale) the challenges faced. Analysis included multidimensional scaling, hierarchical cluster analysis and descriptive statistics (eg, mean ratings). RESULTS: Twenty-five deliverers brainstormed 82 injury prevention/management-related challenges. An eight cluster map was considered the most appropriate representation of the participants' sorting data (mean cluster impact, frequency and difficulty to overcome rating (1-5)): time constraints (3.42, 3.69, 3.12); perceived competence in injury prevention/management (3.36, 3.50, 3.27); navigating participant perceptions and knowledge (3.35, 3.74, 3.49); information and responsibility (3.32, 3.50, 3.26); session planning and structure (3.25, 3.45, 3.07); participant engagement (3.13, 3.47, 3.08); responding to individual needs (3.07, 3.42, 2.92) and access to injury management resources (2.87, 3.25, 3.17). CONCLUSION: Limited time created injury prevention/management challenges for programme deliverers when planning and modifying sport programmes for physically inactive women. Injury prevention/management should be integrated into programme design and delivery principles. Programme deliverers need education/training and access to injury prevention/management resources (eg, activity modification) and engagement/communication strategies tailored for physically inactive women. Public health funders, coaching course accreditors, programme designers and deliverers can use these insights to develop strategies to minimise injury risk and effect systemic change in sport programme delivery.

RESUMO

Appropriate dietary intake has been found to positively impact athletes' performance, body composition and recovery from exercise. Strategies to optimise dietary intake often involve targeting one or more of the many factors that are known to influence dietary intake. This review aims to investigate the types and effectiveness of interventions used to impact modifiable factors of dietary intake in athletes. MEDLINE, CINAHL, SPORTDiscus and Web of Science were searched from inception to May 2022 for intervention studies that measured dietary intake with a quantitative tool and explored at least one factor thought to influence the dietary intake of adult athletes. Study quality was assessed using the ADA Quality Criteria Checklist: Primary Research. Twenty-four studies were included. The most common interventions focused on nutrition education (n 10), macronutrient adjustment (n 7) and physical activity (n 5). The three most common factors thought to influence dietary intake addressed were nutrition knowledge (n 12), hunger and appetite (n 8), and body composition (n 4). Significant changes in dietary intake were found in sixteen studies, with nutrition education interventions returning significant results in the largest proportion of studies (n 8). Study quality within this review was mostly average (n 4 < 50 %, n 19 50-80 %, n 1 > 80 %). As studies included were published between 1992 and 2021, interventions and factors explored in older studies may require up-to-date research to investigate possible differences in results due to time-related confounders.

RESUMO

BACKGROUND & OBJECTIVES: Low muscle mass, measured using computed tomography (CT), is associated with poor surgical outcomes. We aimed to include CT-muscle mass in malnutrition diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria, compare it to the International Classification of Diseases 10th Revision (ICD-10) criteria, and assess the impact on postoperative outcomes after oesophagogastric (OG) cancer surgery. METHODS: One hundred and eight patients who underwent radical OG cancer surgery and had preoperative abdominal CT imaging were included. GLIM and ICD-10 malnutrition data were assessed against complication and survival outcomes. Low CT-muscle mass was determined using predefined cut-points. RESULTS: GLIM-defined malnutrition prevalence was significantly higher than ICD-10-malnutrition (72.2% vs. 40.7%, p < 0.001). Of the 78 patients with GLIM-defined malnutrition, low muscle mass (84.6%) was the predominant phenotypic criterion. GLIM-defined malnutrition was associated with pneumonia (26.9% vs. 6.7%, p = 0.010) and pleural effusions (12.8% vs. 0%, p = 0.029). Postoperative complications did not correlate with ICD-10 malnutrition. Severe GLIM (HR: 2.51, p = 0.014) and ICD-10 (HR: 2.15, p = 0.039) malnutrition were independently associated with poorer 5-year survival. CONCLUSIONS: GLIM criteria appear to identify more malnourished patients and more closely relate to surgical risk than ICD-10 malnutrition, likely due to incorporating objective muscle mass assessment.

RESUMO

Sports foods are convenient alternatives to everyday foods to fuel performance. Strong scientific evidence supports their use; however, commercial sports foods are classified by the NOVA system as ultra-processed foods (UPF). Consumption of UPF has been associated with poor mental and physical health, but little is known about athletes' consumption of and attitudes towards sports foods as a source of UPF. The aim of this cross-sectional study was to assess Australian athletes' intake of and attitudes towards sports foods and UPF. Adult athletes were recruited to complete an anonymous online survey via social media between October 2021 and February 2022. Data were analysed using descriptive statistics, and Pearson's χ2 test was used to assess potential relationships between categorical demographic variables and consumption of sports foods. One hundred forty Australian adults participating in recreational (n 55), local/regional (n 52), state (n 11), national (n 14) or international (n 9) sports completed the survey. Ninety-five percent reported consuming sports foods within the past 12 months. Participants consumed sports drinks most commonly (73 %) and isolated protein supplements most frequently (40 % at least once per week). Participants reported everyday foods to be more affordable, taste better, present less risk of banned substances, but less convenient and greater risk of spoilage. Half (51 %) of participants reported concern about health effects of UPF. Participants reported regular UPF consumption despite taste and cost-related preferences for everyday foods and health concerns regarding UPF intake. Athletes may need support to identify and access safe, affordable, convenient, minimally processed alternatives to sports foods.

RESUMO

BACKGROUND: Entrustable professional activities (EPAs) describe key workplace activities and are increasingly being used for student work-based assessment. An EPA-based work-based assessment tool offers potential to increase understanding of dietetics student skill development and opportunity for standardised work-based student assessment. OBJECTIVE: To determine construct validity and educational impact of an EPA work-based assessment tool for dietetics placement students in clinical settings. DESIGN: Using a time series design, supervisor and student self-assessment data collected from an EPA-based assessment tool from three cohorts of dietetics students and supervisors from 2017-2019 was analyzed. PARTICIPANTS AND SETTING: Dietetics students (n = 145) from an accredited dietetic training program in Australia and affiliated metropolitan and rural hospitals. MAIN OUTCOME MEASURES: Construct validity was determined through analysis of supervisor evaluation of student performance against EPAs over time. Educational impact was determined through comparing student performance across EPAs to predicted milestones to identify areas of least entrustment. STATISTICAL ANALYSES PERFORMED: Student performance over time and differences between student self-assessment and supervisor assessment for each EPA were investigated using Wilcoxon signed-rank tests and linear mixed-model analysis. Descriptive statistics summarised student performance against each EPA. RESULTS: Performance significantly increased over time in 35 out of 37 EPAs. Significant differences between supervisor and student self-assessment were evident in 9 out of 37 EPAs. Dietetics student performance varied across EPAs with 88.2% of students achieving entrustment for nutrition management EPAs compared with 100% for professionalism EPAs. CONCLUSIONS: The tool's construct validity was established. EPAs identified areas of Nutrition Care Process skills development requiring additional support. Data collected by the tool can inform teaching.

RESUMO

BACKGROUND: A Mediterranean diet (MD) appears to be beneficial in non-alcoholic fatty liver disease (NAFLD) patients in Mediterranean countries; however, the acceptability of a MD in non-Mediterranean populations has not been thoroughly explored. The present study aimed to explore the acceptability through understanding the barriers and enablers of the MD and low-fat diet (LFD) interventions as perceived by participating Australian adults from multicultural backgrounds with NAFLD. METHODS: Semi-structured telephone interviews were performed with 23 NAFLD trial participants at the end of a 12-week dietary intervention in a multicentre, parallel, randomised clinical trial. Data were analysed using thematic analysis. RESULTS: Participants reported that they enjoyed taking part in the MD and LFD interventions and perceived that they had positive health benefits from their participation. Compared with the LFD, the MD group placed greater emphasis on enjoyment and intention to maintain dietary changes. Novelty, convenience and the ability to swap food/meals were key enablers for the successful implementation for both of the dietary interventions. Flavour and enjoyment of food, expressed more prominently by MD intervention participants, were fundamental components of the diets with regard to reported adherence and intention to maintain dietary change. CONCLUSIONS: Participants randomised to the MD reported greater acceptability of the diet than those randomised to the LFD, predominantly related to perceived novelty and palatability of the diet.

RESUMO

Iron metabolism research in the past decade has identified menstrual blood loss as a key contributor to the prevalence of iron deficiency in premenopausal females. The reproductive hormones estrogen and progesterone influence iron regulation and contribute to variations in iron parameters throughout the menstrual cycle. Despite the high prevalence of iron deficiency in premenopausal females, scant research has investigated female-specific causes and treatments for iron deficiency. In this review, we provide a comprehensive discussion of factors that influence iron status in active premenopausal females, with a focus on the menstrual cycle. We also outline several practical guidelines for monitoring, diagnosing, and treating iron deficiency in premenopausal females. Finally, we highlight several areas for further research to enhance the understanding of iron metabolism in this at-risk population.

RESUMO

Entrustable professional activities (EPAs) is a recent concept that helps operationalise competency-based education. In this paper, we report on the development of EPAs and incorporation into an e-portfolio for work-based assessment of final year dietetics students in a community and public health professional placement. We aimed to determine the utility of the EPAs for work-based assessment in this context. We used action research methodology to conduct broad consultation with students and supervisors using anonymous surveys and focus groups to understand their beliefs and attitudes towards work-based assessment. Consequently, 40 EPAs with an accompanying four-point entrustment scale were developed and mapped to the National Competency Standards for Dietitians in Australia. The EPAs and assessment tool were piloted and evaluated via an anonymous online user survey across three cohorts of students (n = 133) and supervisors (n = 67). Following mediocre pilot year evaluation results, EPAs were revised and reduced in number. While students positively evaluated the e-portfolio, their appraisal of the EPAs and entrustment scale was less positive compared to supervisors. Supervisor evaluation of the EPA-based e-portfolio supported the validity, feasibility and acceptability of this novel assessment method in a community and public health setting. Assessment using EPAs, and the resulting educational data collected by the tool, offers potential for individual learners to identify areas needing development during placement, as well as potential to inform curriculum improvements and increase understanding of learning opportunities and outcomes for dietetic students in community and public health settings.

RESUMO

Rates of childhood obesity within Australia continue to rise, with consumption of sugar-sweetened beverages one contributing factor. Community sport provides an opportunity to implement policies promoting water as the beverage of choice. However, the attitudes of parents toward a water-only policy are not known. This cross-sectional study aimed to investigate parents' opinions towards beverage consumption and a water-only policy. Data were collected from participants (n = 159) using an investigator-designed questionnaire, administered using iPads, at a junior Triathlon Victoria event. Water was the most popular beverage provided before (75%), during (85%) and after (61%) sport. Parents were more likely to provide sports drinks to children older than 14 years (27%). Three-quarters (77%) of parents reported having received no information regarding hydration requirements. Parents rated the importance of hydration prior to, during and after a triathlon as high (9.08 ± 1.2, 8.76 ± 1.3 and 9.30 ± 0.4 out of 10, respectively). Parents were supportive of a water-only policy at all junior triathlon events and all junior sporting events (7.94 ± 1.3 and 7.86 ± 1.9, respectively). There was less support for a water-only policy for adult triathlons (6.40 ± 3.1). A water-only drink policy at junior sport is viewed positively by parents. This warrants further research and policy development to facilitate behaviour change.

RESUMO

AIM: This rapid review of reviews aimed to determine the extent of research undertaken on the effectiveness of dietary interventions for individuals with a mental disorder. METHODS: Three databases (MEDLINE, Embase, Cochrane Reviews and Cochrane Trials) were searched to February 2021 for systematic reviews including experimental studies assessing the effectiveness of dietary interventions with physical or mental health related outcomes in adults or children with one or more of: severe mental illness, depression or anxiety, eating disorders, or substance use disorder. Results are presented descriptively. RESULTS: The number of included reviews was 46 (67% in severe mental illness, 20% in depression and anxiety, 7% in eating disorders, and 7% in substance use disorders). Most reviews were published since 2016 (59%), and included studies conducted in adults (63%). Interventions in the eating disorders and severe mental illness reviews were predominantly education and behaviour change, whereas interventions in the substance use disorders, and depression and anxiety reviews were predominantly supplementation (e.g. omega-3). Twenty-eight and twelve of the reviews respectively reported mental health and dietary outcomes for one or more included studies. Most reviews in severe mental illness, and depression and anxiety reported conclusions supporting the positive effects of dietary intervention, including positive effects on weight-related or mental health outcomes, and on mental health outcomes, respectively. CONCLUSIONS: A larger number of systematic reviews were identified which evaluated dietary interventions in individuals with severe mental illness, and depression and anxiety, compared with substance use disorders, and eating disorders. Dietary intervention is an important component of the treatment that should be available to individuals living with mental disorders, to support their physical and mental health.

RESUMO

AIM: The aim of this study was to explore nutrition professionals' perspectives of nutrition graduates' employability skills, and knowledge and skills required in the industry to understand gaps in undergraduate nutrition curriculum. METHODS: Nutrition professionals (n = 26) across Australia were approached to participate in semi-structured interviews via telephone in 2018. Interviews were transcribed verbatim, data analysed using thematic analysis, and results interpreted and discussed. RESULTS: Nine participants across six work environments completed interviews. Common work roles were identified in their diverse areas of practice: nutrition educators, food developers, team members, and business leaders. Nutrition professionals identified that, in addition to evidence-based discipline knowledge, key skills and knowledge needed for their roles were interpersonal communication, including writing and listening. Participants highlighted the need for employability skills to be embedded within curriculum with emphasis on professional skills, business skills and discipline-specific skills in communicating complex science messages to a range of audiences. Networking, and formal and informal work-integrated learning were viewed as important vehicles for developing required skills. Participants expected that universities develop curriculum to address gaps; however, reflection by the academic researchers suggested this should be a joint role. CONCLUSIONS: Early career planning, professional skill development, work experience and networking opportunities should enhance graduate employability.

RESUMO

Athletes' dietary intakes sometimes do not meet sports nutrition guidelines. Nutrition knowledge (NK) is one factor that may influence dietary intake, but NK measurement tools are often outdated or unvalidated, and results regarding athletes' NK are equivocal. The aims of this systematic review were to update previous systematic reviews by examining athletes' NK and to assess the relationship between athletes' general NK, sport NK and dietary intake. MEDLINE, CINAHL, Scopus, SPORTDiscus, Web of Science and Cochrane were searched for studies published between November 2015 and November 2020 that provided a quantitative measure of NK and described the NK tool used. Twenty-eight studies were included, study quality was assessed using JBI checklists and data on NK score and diet intake was extracted. Eight studies utilised validated, up-to-date NK measurement tools. Mean general and sport NK% scores varied between 40·2% ± 12·4 and 70 % ± 9. Mean protein and carbohydrate consumption was 1·1-3·4 g/kg.bw/d and 2·4-4·6 g/kg.bw/d, respectively. Weak-to-moderate, positive associations were found between NK and positive dietary behaviours. Due to a wide variety of NK measurement tools used, it is difficult to synthesise results to determine overall NK in athletes. Overall, there appears to be a low standard of knowledge. Quality of measurement tools for NK has improved but remains an issue. Future studies should use relevant, current validated NK tools or validate tools in their study population. More research is needed into the relationship between NK and other modifiable factors influencing dietary intake.

RESUMO

AIM: This scoping review aimed to explore the extent of the evidence of experimental studies evaluating the cost effectiveness of dietary interventions in individuals with mental disorders. METHODS: Five databases (CINAHL, EMBASE, MEDLINE, PsycINFO and Scopus) were searched to October 2020 for cost-analysis studies of interventions aiming to improve dietary intake in people with mental disorders. No restriction was placed on participant age, mental disorder type or intervention design. Results are presented narratively. RESULTS: Of 2753 articles identified, 13 articles reporting on eight studies were included. Studies were RCTs (n = 5), cluster RCT (n = 1), cluster preference RCT (n = 1), and pre-post test (n = 1). Seven studies were in community settings (eg, outpatient clinics), and one study in the community housing setting. All studies were in adults, seven included male and female participants, and one included only females. Defined mental disorder diagnoses included serious/severe mental disorders (n = 3), major depression (n = 2), schizophrenia, schizoaffective disorder or first-episode psychosis (n = 1), any mental disorder (n = 1), and bulimia nervosa (n = 1). Five interventions were multi-behaviour, two were diet only and one was eating disorder treatment. Cost analyses included cost-utility (n = 3), cost-effectiveness (n = 1), cost-utility and cost-effectiveness (n = 3), and a costing study (n = 1). Two studies (25%) reported positive results in favour of cost effectiveness, and four studies reported a mix of positive and neutral results. CONCLUSIONS: There is limited evidence evaluating the cost effectiveness of dietary interventions in individuals with mental disorders. Additional studies in various settings are needed to confirm cost effectiveness of different interventions.

RESUMO

Healthcare staff are in a unique position of understanding client experiences, physiological impacts of client behaviour, the local healthcare system and the physical environment in which the services operate. Their perspectives may provide insights into the feasibility and effectiveness of existing models of diabetes care and suggestions for improvements to models of care (MoC). The objective of this qualitative study was to explore the experiences of healthcare staff delivering care for people with diabetes at the request of an existing healthcare service. Semi-structured interviews were conducted with 21 healthcare staff from three community health centres in one region of Victoria, Australia, in 2018. Interviews were audio-recorded and transcribed verbatim. Data were subject to qualitative content analysis and, subsequently, emerging themes were classified at individual, relationship, community and societal levels of the social-ecological model (SEM). Perceived barriers of access to health services using the current MoC included a lack of public transport, low socioeconomic status, job insecurity (resulting in an inability to take time away from work) and inflexible appointment times, all of which negatively impact diabetes management. Perceived enablers included having a co-located, multidisciplinary team, a holistic approach to diabetes management and motivation resulting from improvement in diabetes-related health outcomes. The findings indicate that there is potential to improve the service in this region by adopting a more integrated, team-focused and accessible MoC.

RESUMO

BACKGROUND: Increased intestinal permeability (IP) is associated with sepsis in the intensive care unit (ICU). This study aimed to pilot a sensitive multisugar test to measure IP in the nonfasted state. METHODS: Critically ill, mechanically ventilated adults were recruited from 2 ICUs in Australia. Measurements were completed within 3 days of admission using a multisugar test measuring gastroduodenal (sucrose recovery), small-bowel (lactulose-rhamnose [L-R] and lactulose-mannitol [L-M] ratios), and whole-gut permeability (sucralose-erythritol ratio) in 24-hour urine samples. Urinary sugar concentrations were compared at baseline and after sugar ingestion, and IP sugar recoveries and ratios were explored in relation to known confounders, including renal function. RESULTS: Twenty-one critically ill patients (12 males; median, 57 years) participated. Group median concentrations of all sugars were higher following sugar administration; however, sucrose and mannitol increases were not statistically significant. Within individual patients, sucrose and mannitol concentrations were higher in baseline than after sugar ingestion in 9 (43%) and 4 (19%) patients, respectively. Patients with impaired (n = 9) vs normal (n = 12) renal function had a higher L-R ratio (median, 0.130 vs 0.047; P = .003), lower rhamnose recovery (median, 15% vs 24%; P = .007), and no difference in lactulose recovery. CONCLUSION: Small-bowel and whole-gut permeability measurements are possible to complete in the nonfasted state, whereas gastroduodenal permeability could not be measured reliably. For small-bowel IP measurements, the L-R ratio is preferred over the L-M ratio. Alterations in renal function may reduce the reliability of the multisugar IP test, warranting further exploration.

RESUMO

OBJECTIVE: To assess the effectiveness of interventions using a nudge approach to reduce sugar-sweetened beverage purchases in community sports settings. METHODS: A total of 155 community sporting organisations participating in VicHealth funded programs were invited to nominate a nudge based on a traffic light approach to drinks classification. These included limit red drinks, red drinks off display, water the cheapest option, and meal deals. Sales data was collected for a predetermined period prior to and following the introduction of the nudge. Nudges were classified initially on whether they were implemented to VicHealth standards. Appropriately implemented nudges were classified as successful if they achieved a relative decrease in sales from drinks classified as red. RESULTS: In all, 148 organisations trialled 195 nudges; 15 (7.7%) were successful and 20 (10.3%) were appropriately implemented but unsuccessful. Limit red drinks was the most frequently attempted nudge (30.8%). Red drinks off display had the greatest rate of success (20.0%). CONCLUSIONS: Red drinks off display was the simplest and most successful nudge. Implications for public health: Guidelines limiting the display of sugar-sweetened beverages may be an effective means of altering consumer behaviour.

RESUMO

(1) Background: Community sport settings present a range of conflicting health behaviours, including the tension between being physically active and consuming discretionary foods. Therefore, community sport settings are considered a promising location for health promotion. The aim of this project was to evaluate perceptions, knowledge and the impact (e.g., barriers and outcomes) of a healthy-canteen (cafeteria) display, based on traffic light labeling (TLL), which was set up at an Australian Basketball Association Managers' Convention and Trade Show. (2) Methods: We set up a healthy 'canteen display and surveyed Basketball managers on their perceptions of the display before (Survey 1) and after (Survey 2) visiting the display. Three months later they were surveyed (Survey 3) on changes made to their community sport canteens. (3) Results: Eighty-eight, 76 and 22 participants completed Surveys 1, 2 and 3, respectively. Participants believed stocking healthy foods and beverages was important (mean 8.5/10). Food waste, lack of consumer interest and price were identified barriers to stocking healthy foods. After visiting the display, 75% were inspired to make changes and 50% were surprised by the differences between their perceptions of the healthfulness of foods and the TLL ratings. Post-convention, 41% and 70% made or had planned healthy changes to their community sport canteen. (4) Conclusions: A healthy-canteen display is a low-cost, easy-to-implement strategy that may be able to direct self-driven improvement in the healthfulness of foods stocked at community canteens and lead to improved nutritional intakes at these venues.

RESUMO

BACKGROUND: A new concept in work-based assessment, Entrustable Professional Activities (EPAs) describe key activities a work-ready practitioner can perform independently. EPAs are widely used in medicine to support competency-based education and are gaining acceptance in other professions such as nursing, pharmacy and dietetics. There is currently no widely accepted work-based assessment tool for student clinical placement assessment in dietetics and EPAs offer potential to address this gap. OBJECTIVES: To design, implement and evaluate a work-based assessment tool using EPAs embedded in an e-portfolio for use in clinical dietetics. SETTING: An accredited dietetic training program in Australian university and affiliated metropolitan and rural hospitals. PARTICIPANTS: Three consecutive cohorts of final year dietetic students (n = 126) and their professional placement supervisors (n = 101). METHODS: A working party consisting of dietetic academics with experience in clinical dietetics and education developed clinical dietetic EPAs and milestones that were mapped to the National Competency Standards for Dietitians in Australia. A design model incorporating multiple rounds of user feedback was used to create an e-portfolio with the EPAs embedded. Students and supervisors were invited to complete anonymous on-line surveys with Likert responses (1 = highly dissatisfied, 5 = highly satisfied) to evaluate the face validity, acceptability and feasibility of the tool. RESULTS: A total of 37 EPAs were developed with an accompanying four-point entrustment scale to measure performance. Evaluation survey response rates were high and ranged from 35 to 45% for students and 57-83% for supervisors across the study period. Both students and supervisors evaluated the tool positively with a mean overall satisfaction of 4.12 ± 0.69 and 4.03 ± 0.68, respectively. Survey items evaluating face validity, feasibility and acceptability scored >3.75 for both groups of users. CONCLUSIONS: The EPA based e-portfolio demonstrated face validity, feasibility and acceptability and offers potential for a widely accepted tool for work-based assessment of clinical dietetic students.
