Navigating the complexity of applying nutrition evidence to individualised care: Summary of an Academy of Nutrition Sciences position paper

Diet is key to the maintenance of health and crucial in the prevention and management of many diseases. Modified nutrient intake may become essential to prevent deficiency, optimise development and health or manage symptoms and disease progression. Adding to the complexity, disease and its treatment can also affect taste, appetite and ability to access and prepare foods. Coupled with this, individual requirements for energy, macronutrients and micronutrients are influenced by factors such as life stage (age, growth, pregnancy, etc.) and health status, which can affect the processes of consuming, digesting, absorbing, metabolising or excreting nutrients. First and foremost, dietary advice must be based on sound evidence if it is to achieve and maintain human health. Furthermore, the practice of nutrition and dietetics must integrate and apply the sciences of food, nutrition, biology, physiology, behaviour management, communication and must also recognise the context that society presents, including the plethora of often conflicting information on diet and health available via the internet and other media sources

Nature of the Evidence Base and Approaches to Guide Nutrition Interventions for Individuals: A Position Paper From the Academy of Nutrition Sciences

This Position Paper from the Academy of Nutrition Sciences is the third in a series which describe the nature of the scientific evidence and frameworks that underpin nutrition recommendations for health. This paper focuses on evidence which guides the application of dietary recommendations for individuals. In some situations, modified nutrient intake becomes essential to prevent deficiency, optimise development and health, or manage symptoms and disease progression. Disease and its treatment can also affect taste, appetite and ability to access and prepare foods, with associated financial impacts. Therefore, the practice of nutrition and dietetics must integrate and apply the sciences of food, nutrition, biology, physiology, behaviour, management, communication and society to achieve and maintain human health. Thus, there is huge complexity in delivering evidence-based nutrition interventions to individuals. This paper examines available frameworks for appraising the quality and certainty of nutrition research evidence, the development nutrition practice guidelines to support evidence implementation in practice and the influence of other sources of nutrition information and misinformation. The paper also considers major challenges in applying research evidence to an individual and suggests consensus recommendations to begin to address these challenges in the future. Our recommendations target three groups; those who deliver nutrition interventions to individuals, those funding, commissioning or undertaking research aimed at delivering evidence-based nutrition practice, and those disseminating nutritional information to individuals

Facilitating participation in health-enhancing physical activity: a qualitative study of parkrun

Background Public health guidelines emphasise the value of vigorous intensity physical activity, but participation levels are low. Purpose This study was aimed at identifying factors contributing to initial and sustained engagement in parkrun in the UK, to inform the design of community-based interventions promoting health-enhancing physical activity. Methods Semi-structured interviews were conducted by telephone with 48 adult participants of parkrun, a national network of weekly, free, volunteer-led, timed 5 km runs in public spaces. The framework approach was used for thematic analysis of transcripts. Results Two overarching themes emerged: freedom and reciprocity. Freedom referred to the accessibility and inclusivity of events, both of which contributed to initial attendance and sustained involvement. Reciprocity related to the dual opportunity for personal gain and for helping others. Anticipation of fitness and health benefits were important for initial motivation. However, additional aspects motivating continued involvement included achievement of time or attendance goals, social cohesion, and contributing to the community. Conclusions Specific features of the parkrun experience encouraged participation including the accessible, inclusive ethos, achievement opportunities, and inherent social support, along with the outdoor natural settings, and integrated volunteer system. The inclusion of these elements in community-based interventions may increase success in initiating and maintaining health-enhancing physical activity

Use of probiotic Lactobacillus preparation to prevent diarrhoea associated with antibiotics: randomised double blind placebo controlled trial

Objective To determine the efficacy of a probiotic drink containing Lactobacillus for the prevention of any diarrhoea associated with antibiotic use and that caused by Clostridium difficile. Design Randomised double blind placebo controlled study. Participants 135 hospital patients (mean age 74) taking antibiotics. Exclusions included diarrhoea on admission, bowel pathology that could result in diarrhoea, antibiotic use in the previous four weeks, severe illness, immunosuppression, bowel surgery, artificial heart valves, and history of rheumatic heart disease or infective endocarditis. Intervention Consumption of a 100 g (97 ml) drink containing Lactobacillus casei, L bulgaricus, and Streptococcus thermophilus twice a day during a course of antibiotics and for one week after the course finished. The placebo group received a longlife sterile milkshake. Main outcome measures Primary outcome: occurrence of antibiotic associated diarrhoea. Secondary outcome: presence of C difficile toxin and diarrhoea. Results 7/57 (12%) of the probiotic group developed diarrhoea associated with antibiotic use compared with 19/56 (34%) in the placebo group (P=0.007). Logistic regression to control for other factors gave an odds ratio 0.25 (95% confidence interval 0.07 to 0.85) for use of the probiotic, with low albumin and sodium also increasing the risk of diarrhoea. The absolute risk reduction was 21.6% (6.6% to 36.6%), and the number needed to treat was 5 (3 to 15). No one in the probiotic group and 9/53 (17%) in the placebo group had diarrhoea caused by C difficile (P=0.001). The absolute risk reduction was 17% (7% to 27%), and the number needed to treat was 6 (4 to 14). Conclusion Consumption of a probiotic drink containing L casei, L bulgaricus, and S thermophilus reduce the incidence of antibiotic associated diarrhoea and C difficile associated diarrhoea. This has the potential to decrease morbidity, healthcare costs, and mortality if used routinely in patients aged over 50

Enhanced referral prioritisation for acute adult dietetic services: A randomised control trial to test a web-based decision training tool

BACKGROUND & AIMS: Dietitians in acute adult services need to prioritise dietetic referrals in order to manage their daily workload and ensure effective treatment of patients. Newly qualified dietitians do not usually receive specific training on prioritisation and could be helped with an evidence-based, effective, decision-training tool that is based on the practice of experienced dietitians. We developed an internationally available web-based decision-training tool designed to improve novice dietitians' ability to make dietetic prioritisation decisions. The training tool comprised of a pre-training task, a post-training task and training materials. The aim of this study was to test the effectiveness of the training tool on novices' ability for dietetic prioritisation. METHODS: Pre-registration dietitians and recent graduates (one-year) from across the UK were invited to participate in this randomised controlled trial (RCT). Each participant made prioritisation decisions on a set of dietetic referral scenarios: 53 scenarios at pre-training and 27 at post-training. After pre-training the intervention group was presented with the training materials, whereas the control group was told to carry on with the post-training task. Participants did not know which group they had been randomly allocated to. We calculated i) level of agreement between decisions made by each novice and experts' consensus using Pearson correlation, intra-class correlation (ICC(2,1)); ii) intra-rater consistency using ICC(1,1) and iii) intra-group consistency using ICC (2,1). We compared group means at pre-training and post-training; estimated effect size using the degree of change from pre- to post-training, and 2-factor mixed ANOVA to assess overall effect of the training across the groups and time-points. RESULTS: 151 participants (69 in control and 82 in intervention) completed the trial. The groups did not differ in demographic characteristics. Both Pearson and ICC(2,1) correlations increased with training intervention; a moderate effect of training was found for both metrics, d = 0.69 (r = 0.32) for the former and d = 0.54 (r = 0.26) for the latter. Intra-rater consistency improved with training but with a small effect size, d = 0.32 (r = 0.16). The intra-group consistency also improved with training: ICC = 0.48 pre-training to 0.61 post-training. CONCLUSIONS: The training tool was found to be effective in improving the novice dietitian's ability to prioritise referrals in the acute adult setting. The training tool is freely available at www.dietitianreferral.org for use by all student or early career dietitians internationally

Dietary Magnesium May Be Protective for Aging of Bone and Skeletal Muscle in Middle and Younger Older Age Men and Women: Cross-Sectional Findings from the UK Biobank Cohort.

Although fragility fractures, osteoporosis, sarcopenia, and frailty are becoming more prevalent in our aging society the treatment options are limited and preventative strategies are needed. Despite magnesium being integral to bone and muscle physiology, the relationship between dietary magnesium and skeletal muscle and bone health has not been investigated concurrently to date. We analysed cross-sectional associations between dietary magnesium and skeletal muscle mass (as fat free mass-FFM), grip strength, and bone density (BMD) in 156,575 men and women aged 39-72 years from the UK Biobank cohort. FFM was measured with bioelectrical impedance and was expressed as the percentage of body weight (FFM%) or as divided by body mass index (FFMBMI). Adjusted mean grip strength, FFM%, FFMBMI, and BMD were calculated according to quintiles of dietary magnesium, while correcting for covariates. Significant inter-quintile differences across intakes of magnesium existed in men and women, respectively, of 1.1% and 2.4% for grip strength, 3.0% and 3.6% for FFM%, 5.1% and 5.5% for FFMBMI, and 2.9% and 0.9% for BMD. These associations are as great or greater than annual measured losses of these musculoskeletal outcomes, indicating potential clinical significance. Our study suggests that dietary magnesium may play a role in musculoskeletal health and has relevance for population prevention strategies for sarcopenia, osteoporosis, and fractures

A case study of the impact of a dietitian in the multi‐disciplinary team within primary care: a service evaluation

AbstractBackgroundExpanding the primary care workforce to alleviate general practitioner (GP) workload, improve access and improve quality of care is a current UK strategy. Evidence suggests dietitians can improve patient outcomes and make cost savings. The present study aimed to evaluate a dietitian working as an expert generalist and first contact practitioner (FCP) in a general practice multi‐disciplinary team (MDT) to provide appropriate care to patients and reduce GP workload.MethodsA dietitian was employed for 6 months at 0.6 full‐time equivalents in a group of general practices in Devon, UK. Data were collected on the referral source, patient satisfaction, health outcomes and changes in prescribing data for all patients seen by the dietitian. Focus groups and interviews provided data to understand the experience of introducing a dietitian into the team.ResultsThis model of service delivery showed the dietitian acting as an expert generalist, a FCP and able to educate the MDT. A range of professionals within the MDT referred patients with a wide range of diagnoses (both paediatric and adults) and the dietitian acted as a FCP for 29% of patients. Saving were made for the optimisation of medicine management.ConclusionsThe dietitian can improve patient‐centred care for several patient groups; enhance learning for staff around nutrition and dietary issues; and contribute to more efficient working and cost savings around prescription of nutritional products. This was an evaluation of one service and further research is needed to understand the value dietitians can contribute and the factors supporting effective and efficient working in this context.</jats:sec
