Factors determining the integration of nutritional genomics into clinical practice by registered dietitians

YesPersonalized nutrition has the potential to improve health, prevent disease and reduce healthcare expenditure. Whilst research hints at positive consumer attitudes towards personalized nutrition that draws upon lifestyle, phenotypic and genotypic data, little is known about the degree to which registered dietitians (RD) are engaged in the delivery of such services. This review sought to determine possible factors associated with the integration of the emerging science of Nutritional Genomics (NGx) into the clinical practice setting by practicing registered dietitians. Scope Search of online databases (Pubmed; National Library of Medicine; Cochrane Library; Ovid Medline) was conducted on material published from January 2000 to December 2014. Studies that sampled practicing dietitians and investigated integration or application of NGx and genetics knowledge into practice were eligible. Articles were assessed according to the American Dietetic Association Quality Criteria Checklist. Key findings Application of nutritional genomics in practice has been limited. Reluctance to integrate NGx into practice is associated with low awareness of NGx, a lack of confidence in the science surrounding NGx and skepticism toward Direct to consumer (DTC) products. Successful application to practice was associated with knowledge about NGx, having confidence in the science, a positive attitude toward NGx, access to DTC products, a supportive working environment, working in the clinical setting rather than the public health domain and being in private rather than public practice. Conclusions There is a need to provide RGs with a supportive working environment that provides ongoing training in NGx and which is integrated with clinical practice

Psycho-markers of weight loss. The roles of TFEQ Disinhibition and Restraint in exercise-induced weight loss

yesEating behaviour traits, namely Disinhibition and Restraint, have the potential to exert an effect on food intake and energy balance. The effectiveness of exercise as a method of weight management could be influenced by these traits. Fifty eight overweight and obese participants completed 12-weeks of supervised exercise. Each participant was prescribed supervised exercise based on an expenditure of 500 kcal/session, 5 d/week for 12-weeks. Following 12-weeks of exercise there was a significant reduction in mean body weight ( 3.26 ± 3.63 kg), fat mass (FM: 3.26 ± 2.64 kg), BMI ( 1.16 ± 1.17 kg/m2) and waist circumference (WC: 5.0 ± 3.23 cm). Regression analyses revealed a higher baseline Disinhibition score was associated with a greater reduction in BMI and WC, while Internal Disinhibition was associated with a larger decrease in weight, %FM and WC. Neither baseline Restraint or Hunger were associated with any of the anthropometric markers at baseline or after 12-weeks. Furthermore, after 12-weeks of exercise, a decrease in Disinhibition and increase in Restraint were associated with a greater reduction in WC, whereas only Restraint was associated with a decrease in weight. Post-hoc analysis of the sub-factors revealed a decrease in External Disinhibition and increase in Flexible Restraint were associated with weight loss. However, an increase in Rigid Restraint was associated with a reduction in %FM and WC. These findings suggest that exercise-induced weight loss is more marked in individuals with a high level of Disinhibition. These data demonstrate the important roles that Disinhibition and Restraint play in the relationship between exercise and energy balance.BBSR

Dying to Talk? Co-producing resources with young people to get them talking about bereavement, death and dying

YesThe Dying to Talk project in Bradford, UK aimed to build resilience in young people around the topic of death, dying and bereavement. Starting conversations early in life could buttress people’s future wellbeing when faced with bereavement and indeed their own mortality. Research indicates that a key feature in young people’s experience of bereavement is ‘powerlessness’ (Ribbens McCarthy, 2007). Drawing on the principles of co-production, young people led the development of the project aimed at encouraging young people to talk about death, using archaeology as a facilitator to those conversations. The partnership between the University of Bradford, the voluntary sector and the young people proved to be a positive and empowering one. It laid the foundations for future collaboration and developed a framework for engaging young people in talking about death, building their resilience for dealing with death and dying in the future – a step towards building a ‘compassionate city’ for young people (Kellehear, 2012)University of Bradford, Higher Education Innovation Fund; AHR

Relationships among tonic and episodic aspects of motivation to eat, gut peptides, and weight before and after bariatric surgery.

yesBackground The interaction between motivation to eat, eating behaviour traits and gut peptides following gastric bypass (GBP) surgery are not fully understood. Setting Danderyd Hospital, Karolinska Institutet, Stockholm, Sweden. Method Appetite and hormone responses to a fixed liquid pre-load were assessed in 12 obese (BMI 45 ± 1.9 kg/m2) participants immediately before, 3 days, 2 months, and 1 year following gastric by-pass (GBP) surgery. Subjective appetite and plasma levels of ghrelin, leptin, insulin and GLP-1 were measured for a 3-hour postprandial period. Eating behaviour traits were also measured using the TFEQR18. Results There was a decrease in TFEQ Emotional Eating (EE) and Uncontrolled Eating (UE) from pre to 1-year post-surgery, but no significant change in Restraint. In addition, there was a reduction in subjective appetite ratings, and alterations in appetite peptides favouring an anorectic response. Pre-surgery EE was significantly related to fasting and AUC ghrelin; UE was associated with AUC desire to eat while there was a significant association between fasting desire to eat and ghrelin (fasting and AUC). 1 year post-surgery, UE was positively related to fasting insulin and Restraint was negatively associated with GLP-1. UE and subjective hunger were positively correlated, while the relationship between desire to eat and ghrelin remained. Conclusion The relationships amongst subjective appetite ratings, eating behaviour traits and appetite peptides in obese patients both before and at one-year post GBP surgery contribute to the reduction in a propensity to over-eat and weight loss

Mothers’ and fathers’ views on the importance of play for their children’s development: gender differences, academic activities, and the parental role

YesBackground: Play is a main driver of children’s cognitive and social development and is crucial for educational success (Ginsburg, 2007). In recent years however, parents and schools are under pressure to prioritise academic targets over play. Aims: The current research investigated parents’ views about three aspects of their children’s play and academic activities. Sample: Predominantly highly educated UK parents (109 mothers and 49fathers) were recruited via social media. Method: Participants were asked to complete an amended online version of the Preschool Play and Learning Questionnaire (Parmar, Harkness, & Super, 2004). The questionnaire consisted of 25 items covering three themes: the importance of play for children’s development, the importance of academic activities, and the importance of parents’ role in their children’s development. The independent variables were the gender of the parent, the gender of their child, and the age group of their child (4 to 7 years, or 8 to 11 years). Results: Parents rated play higher than academic activities or their own roles, but the difference was not noteworthy. However, fathers rated academic activities and the parents’ role significantly higher than mothers did. In addition, parents of girls rated academic activities and their own role, significantly higher than parents of boys. Conclusions: The findings of the current research highlight gender divisions between parents and towards boys and girls regarding the importance of education. Gender roles appear to influence the way parents think about the academic activities their children partake in

Perceptions and experiences of early-adopting registered dietitians in integrating nutrigenomics into practice

yesPurpose - This research explores the perceptions and experiences of early adopters of the technology. Design/Method/Approach - Registered Dietitians (RD´s) (N=14) were recruited from the UK, Canada, South-Africa, Australia, Mexico and Israel. Six qualitative interviews and two focus groups were conducted online using a conference calling platform. Data were recorded, transcribed and thematically analysed. Findings - Early adopters of Nutrigenomics (NGx) were experienced, self-efficacious RD’s who actively sought knowledge of NGx through communication with one another and the broader scientific community. They considered NGx an extension of current practice and believed RD’s had the skills to deliver it. Perceived barriers to widening the application of NGx were linked to skepticism among the wider dietetics community. Proliferation of unregulated websites offering tests and diets was considered ‘pseudoscience’ and detrimental to dietetics fully embracing NGx. The lack of a sustainable public health model for the delivery of NGx was also perceived to hinder progress. Results are discussed with reference to ‘diffusion of innovation theory’. Originality/Value - The views of RD’s who practice NGx have not been previously studied. These data highlight requirements for future dietetic training provision and more inclusive service delivery models. Regulation of NGx services and formal recognition by professional bodies is needed to address the research/practice translation gap

Toward a Romanian version of the Three Factor Eating Questionnaire–R21 for children and adolescents (CTFEQr21): Preliminary psychometric analysis and relation with body composition

YesPurpose. The aim of this study was to develop and validate a Romanian version of the three factor eating questionnaire-r21 for children and adolescents (ctfeqr21), and to assess its psychometric properties and factor structure. Associations between this version of the ctfeqr21 and anthropometric measures as well as body composition were also examined. Design and methods. 153 children and adolescents (68 boys and 95 girls; 10.8 ± 3.5 years) took part in this study (bmi of 17.7 ± 3.1 kg/m²). The participants were first interviewed to ascertain their understanding of the ctfeq-r21 and were then asked to self-complete the questionnaire. Height and weight were measured and body composition assessed using bio impedance analyzers (Tanita MC 780). Results. The CTFEQr21 showed satisfactory internal consistency (cronbach’s α=0.78). Cronbach’s alpha coefficients were 0.55 for CR, 0.75 for UE, and 0.76 for EE separately. UE and EE were found to be significantly correlated (r=0.54, p<0.05). The three factors explained 43% of the total variance. Correlation between CR, UE and EE with body weight, BMI and FFM were significant but low to moderate with coefficients ranging from 0.20 to 0.37. The higher the CR, UE and EE tertiles, the higher the weight, fat mass (kg) and fat-free mass values. Conclusions. According to the psychometric analysis of the questionnaire, the proposed version of the CTFEQr21 proposed here is a satisfactory tool to assess eating behaviors in Romanian child population that remains to be further developed

Validation of a child version of the three-factor eating questionnaire in a Canadian sample - a psychometric tool for the evaluation of eating behaviour

YesObjective: To examine score validity and reliability of a Child version of the 21-item Three-Factor Eating Questionnaire (CTFEQ-R21) in a sample of Canadian children and adolescents and its relationship with body mass index (BMI) z-scores and food/taste preferences. Design: Cross-sectional study. Setting: School-based. Subjects: 158 children, 63 boys (11.5±1.6 years) and 95 girls (11.9±1.9 years). Results: The exploratory factor analysis revealed that the CTFEQ-R21 was best represented by four factors with item 17 removed (CFFEQ-R20) representing Cognitive Restraint (CR), Cognitive Uncontrolled Eating (UE 1), External Uncontrolled Eating (UE 2), and Emotional Eating (EE) and accounted for 41.2% of the total common variance, with good scale reliability. ANOVAs revealed that younger children reported higher UE 1 scores and CR scores compared to older children, and boys who reported high UE 1 scores had significantly higher BMI Z-scores. Children with high UE 1 scores reported a greater preference for high protein and fat foods, and high-fat savoury (HFSA) and high-fat sweet (HFSW) foods. Higher preference for high protein, fat, and carbohydrate foods, and HFSA, HFSW, and low-fat savoury foods was found in children with high UE 2 scores. Conclusions: This study suggests that the CFFEQ-R20 can be used to measure eating behaviour traits and associations with BMI z-scores and food/taste preferences in Canadian children and adolescents. Future research is needed to examine the validity of the questionnaire in larger samples and in other geographical locations, as well as the inclusion of extraneous variables such as parental eating or socio-economic status

The Muslim headscarf and face perception: "they all look the same, don't they?"

YesThe headscarf conceals hair and other external features of a head (such as the ears). It therefore may have implications for the way in which such faces are perceived. Images of faces with hair (H) or alternatively, covered by a headscarf (HS) were used in three experiments. In Experiment 1 participants saw both H and HS faces in a yes/no recognition task in which the external features either remained the same between learning and test (Same) or switched (Switch). Performance was similar for H and HS faces in both the Same and Switch condition, but in the Switch condition it dropped substantially compared to the Same condition. This implies that the mere presence of the headscarf does not reduce performance, rather, the change between the type of external feature (hair or headscarf) causes the drop in performance. In Experiment 2, which used eye-tracking methodology, it was found that almost all fixations were to internal regions, and that there was no difference in the proportion of fixations to external features between the Same and Switch conditions, implying that the headscarf influenced processing by virtue of extrafoveal viewing. In Experiment 3, similarity ratings of the internal features of pairs of HS faces were higher than pairs of H faces, confirming that the internal and external features of a face are perceived as a whole rather than as separate components.The Educational Charity of the Federation of Ophthalmic and Dispensing Opticians
