RESUMO

There is a substantial research base for addictive eating with development of interventions. The current 3-arm RCT aimed to investigate the efficacy of the TRACE (Targeted Research for Addictive and Compulsive Eating) program to decrease addictive eating symptoms and improve mental health. Participants (18-85 yrs) endorsing ≥3 addictive eating symptoms were randomly allocated to 1) active intervention, 2) passive intervention, or 3) control group. Primary outcome was change in addictive eating symptoms 3-months post-baseline measured by the Yale Food Addiction Scale. Depression, anxiety and stress were also assessed. A total of 175 individuals were randomised. Using Linear Mixed Models, from baseline to 3-months, there was significant improvement in symptom scores in all groups with mean decrease of 4.7 (95% CI: -5.8, -3.6; p < 0.001), 3.8 (95% CI: -5.2, -2.4; p < 0.001) and 1.5 (95% CI: -2.6, -0.4; p = 0.01) respectively. Compared with the control group, participants in the active intervention were five times more likely to achieve a clinically significant change in symptom scores. There was a significant reduction in depression scores in the active and passive intervention groups, but not control group [-2.9 (95% CI: -4.5, -1.3); -2.3 (95% CI: -4.3, -0.3); 0.5 (95% CI: -1.1, 2.1), respectively]; a significant reduction in stress scores within the active group, but not passive intervention or control groups [-1.3 (95% CI: -2.2, -0.5); -1.0 (95% CI: -2.1, 0.1); 0.4 (95% CI: -0.5, 1.2), respectively]; and the reduction in anxiety scores over time was similar for all groups. A dietitian-led telehealth intervention for addictive eating in adults was more effective than a passive or control condition in reducing addictive eating scores from baseline to 6 months.

RESUMO

BACKGROUND: Interest in addictive eating continues to grow from both a research and clinical perspective. To date, dietary assessment alongside food addiction status is limited, with management options for addictive eating behaviours variable, given the overlap with myriad conditions. The aim of this study was to report the dietary intake and quality-of-life outcomes from a personality-targeted motivational interviewing intervention delivered by dietitians using telehealth. METHODS: The study was conducted in adults exceeding their healthy-weight range with symptoms of addictive eating, as defined by the Yale Food Addiction Scale. The 52 participants were randomised to either intervention or control, with 49 participants commencing the intervention. Individuals participated in the 3-month, three-session FoodFix interventions, with dietary outcomes assessed by the Australian Eating Survey and quality of life assessed using the SF-36 at baseline and 3 months. RESULTS: There were small-to-moderate effect sizes, specifically in the intervention group for decreased added sugar intake, increased protein intake, increased meat quality and increased vegetable servings per day. Six out of eight quality-of-life domains had small-to-moderate effect sizes. CONCLUSIONS: This intervention has highlighted the need for further research in larger sample sizes to assess dietary behaviour change by those who self-report addictive eating.

RESUMO

BACKGROUND: Few interventions for food addiction (FA) report on dietary intake variables. The present study comprised a three-arm randomised controlled trial in adults with symptoms of FA. The aim was to evaluate dietary intake, sleep and physical activity resulting from a dietitian-led telehealth intervention at 3 months. METHODS: Adults with ≥3 symptoms of FA and a body mass index > 18.5 kg/m2 were recruited. Dietary intake including energy, nutrients and diet quality were assessed by a validated food frequency questionnaire in addition to sleep quality and physical activity (total min) and compared between groups and over time. Personalised dietary goals set by participants were examined to determine whether improvements in percent energy from core and non-core foods were reported. RESULTS: The active intervention group was superior compared to the passive intervention and control groups for improvements in percent energy from core (6.4%/day [95% confidence interval (CI) -0.0 to 12.9], p = 0.049), non-core foods (-6.4%/day [95% CI -12.9 to 0.0], p = 0.049), sweetened drinks (-1.7%/day [95% CI -2.9 to -0.4], p = 0.013), takeaway foods (-2.3%/day [95% CI -4.5 to -0.1], p = 0.045) and sodium (-478 mg/day [95% CI -765 to -191 mg], p = 0.001). CONCLUSIONS: A dietitian-led telehealth intervention for Australian adults with FA found significant improvements in dietary intake variables. Setting personalised goals around nutrition and eating behaviours was beneficial for lifestyle change.

RESUMO

BACKGROUND: There is a lack of understanding of the potential utility of a chatbot integrated into a website to support healthy eating among young adults. Therefore, the aim was to interview key informants regarding potential utility and design of a chatbot to: (1) increase young adults' return rates and engagement with a purpose-built healthy eating website and, (2) improve young adults' diet quality. METHODS: Eighteen qualitative, semi-structured interviews were conducted across three stakeholder groups: (i) experts in dietary behaviour change in young adults (n = 6), (ii) young adult users of a healthy eating website (n = 7), and (iii) experts in chatbot design (n = 5). Interview questions were guided by a behaviour change framework and a template analysis was conducted using NVivo. RESULTS: Interviewees identified three potential roles of a chatbot for supporting healthy eating in young adults; R1: improving healthy eating knowledge and facilitating discovery, R2: reducing time barriers related to healthy eating, R3: providing support and social engagement. To support R1, the following features were suggested: F1: chatbot generated recommendations and F2: triage to website information or externally (e.g., another website) to address current user needs. For R2, suggested features included F3: nudge or behavioural prompts at critical moments and F4: assist users to navigate healthy eating websites. Finally, to support R3 interviewees recommended the following features: F5: enhance interactivity, F6: offer useful anonymous support, F7: facilitate user connection with content in meaningful ways and F8: outreach adjuncts to website (e.g., emails). Additional 'general' chatbot features included authenticity, personalisation and effective and strategic development, while the preferred chatbot style and language included tailoring (e.g., age and gender), with a positive and professional tone. Finally, the preferred chatbot message subjects included training (e.g., would you like to see a video to make this recipe?), enablement (e.g., healthy eating doesn't need to be expensive, we've created a budget meal plan, want to see?) and education or informative approaches (e.g., "Did you know bananas are high in potassium which can aid in reducing blood pressure?"). CONCLUSION: Findings can guide chatbot designers and nutrition behaviour change researchers on potential chatbot roles, features, style and language and messaging in order to support healthy eating knowledge and behaviours in young adults.

RESUMO

BACKGROUND: Mental health is a rapidly evolving area of practice for dietitians. The role of dietitians in supporting the physical health of consumers experiencing mental illness is becoming more widely recognised given the importance of lifestyle interventions for physical health. The present study aimed to explore the dietitian role in mental health services as well as identify barriers and enablers to service delivery. METHODS: This was a cross-sectional survey of dietitians currently employed in any capacity in public and private mental health services. An online survey comprised of questions pertaining to four domains, including demographics, role and service provision, experience and supervision, barriers/challenges and drivers/enablers was completed and included closed and open-ended responses. RESULTS: In total, 48 responses were included. The mean ± SD age of respondents was 36.1 ± 10.9 years (range 23-67 years) with the majority working in inpatient settings. The top three tasks respondents reported conducting were individual consultations (n = 47; 98%), group programs (n = 23; 48%) and multidisciplinary team meetings. Barriers included a lack of awareness from others regarding a dietitian's role in mental health, and a lack of specific tools for nutrition screening. More training, resources and increased evidence base to guide practice would enable better service provision. CONCLUSIONS: The present study provides insights regarding the possible drivers and barriers to effective service provision for dietitians working in mental health services focusing on the local contexts of respondents. The findings highlight the importance and value of working collaboratively within a multidisciplinary team.

RESUMO

BACKGROUND: Despite economic growth, Cambodia continues to have high rates of malnutrition, anaemia and nutrition-related deficiencies. Government policies promote nutrition strategies, although dietary intake data is limited. A detailed synthesis of existing intake data is needed to inform nutrition policy and practice change. This review aims to characterise and assess quality of dietary assessment methods and outcomes from individual-level 'whole diet' studies of Khmer people living in Cambodia. METHODS: Searches were conducted using PRISMA-ScR guidelines. Included papers reported dietary intake at an individual level for 'whole diet'. Studies using secondary data or lacking dietary assessment details were excluded. Extracted data included dietary assessment features, nutrient/food group intakes and database. RESULTS: Nineteen publications (15 studies) were included, with nine carried out among children under 5 years and six among women. Eleven studies reported intake by food groups and four by nutrients, prominently energy, protein, vitamin A, iron, calcium and zinc. Inconsistent intakes, food groupings and reporting of study characteristics limited data synthesis. All but one study used 24-h recalls. Trained local fieldworkers used traditional interview-administered data collection and varied portion estimation tools. Food composition databases for analysis were not tailored to the Cambodian diet. Overall quality was rated as 'good'. CONCLUSIONS: We recommend the development of a best-practice protocol for conducting dietary assessment, a Cambodia-specific food composition database and a competent trained workforce of nutrition professionals, with global support of expertise and funding for future dietary assessment studies conducted in Cambodia.

RESUMO

BACKGROUND: Focused antenatal care currently implemented in Tanzania recommends that women receive nutrition care during routine clinic visits. However, little detail is documented in regard to the nutrition information provided to pregnant women during these visits. The present study aimed to investigate whether pregnant women recalled nutrition information or support provided and, if so, who provided this during routine antenatal clinic visits. The secondary aim was to determine how pregnant women intended to implement the information and what mode of delivery was preferred for receiving nutrition information. METHODS: An exploratory cross-sectional study comprising exit interviews was conducted with 50 pregnant women attending antenatal clinics in three regional referral hospitals in Dar es Salaam, Tanzania. RESULTS: All participants (n = 50) reported receiving nutrition care from healthcare workers in regard to; haemoglobin checks (79% of participants), iron and folic acid supplementation (70%), weight measurement (70%), eating advice (60%), and dietary intake assessment (38%). However, the information recalled on each category was inconsistent. For 60% of participants, nurses were reported as the source of nutrition care during pregnancy, followed by medical doctors (22%). The most preferable mode for receiving nutrition information was reported as individual face-to-face sessions with health practitioners, followed by mobile phone. All of the participants who received nutrition information indicated that they intended to implement. CONCLUSIONS: Nurses were the main source of nutrition information for pregnant women attending antenatal clinics, followed by medical doctors. However, the content of nutrition information recalled by participants was inconsistent. Healthcare facilities need to implement strategies to ensure pregnant women understand and can implement nutrition information provided by healthcare workers during routine antenatal care.

RESUMO

OBJECTIVE: Body image concerns and extreme weight control behaviors frequently develop in childhood indicating an important age group for the implementation of universal-selective prevention approaches. This systematic review aimed to evaluate the effect of universal-selective prevention interventions addressing disordered eating, body image concerns, and/or extreme weight control behaviors in children aged 6-12 years. METHOD: Nine databases were searched up to April 2021. Studies were included if they delivered a universal-selective prevention intervention to children aged 6-12 years and reported outcomes relating to body image, disordered eating, or weight control behaviors. The review was conducted in line with the PRISMA Guidelines. RESULTS: A total of 42 articles describing 39 studies included in the review, with most (n = 24; 57%) classified as neutral quality. Thirty studies implemented an eating disorder specific universal-selective program and nine implemented lifestyle interventions plus content to address disordered eating risk factors. Meta-analysis (n = 16 studies) revealed an improvement in body image-related outcomes across all studies (standardized mean difference [SMD] 0.26 [95%CI 0.01, 0.51]); with a high level of heterogeneity (Î2 = 89.9%; p < .01). Meta-analysis according to gender revealed a general improvement in body image-related outcomes for girls (SMD 0.40 [95%CI 0.07, 0.73]), but not boys (SMD 0.23 [95%CI -0.24, 0.70]). DISCUSSION: By investigating child, parental and teaching interventions and including outcomes such as weight control and disordered eating behaviors, a trend toward a reduction in eating disorder risk factors was observed, particularly body image-related outomes in girls. Future directions include embedded disordered eating prevention materials within existing lifestyle interventions and inclusion of more diverse samples.


OBJETIVO: Las preocupaciones sobre la imagen corporal y los comportamientos de control de peso extremo se desarrollan con frecuencia en la infancia, lo que indica un grupo de edad importante para la implementación de enfoques de prevención universal-selectiva. Esta revisión sistemática tuvo como objetivo evaluar el efecto de las intervenciones de prevención universal-selectivas que abordan la alimentación disfuncional, los problemas de imagen corporal y/o los comportamientos extremos de control de peso en niños de 6 a 12 años de edad. MÉTODO: Se realizaron búsquedas en nueve bases de datos hasta abril 2021. Se incluyeron estudios que habían incluido una intervención de prevención universal-selectiva en niños de 6 a 12 años de edad e informaron resultados relacionados con la imagen corporal, la alimentación disfuncional o los comportamientos de control de peso. El examen se llevó a cabo de conformidad con los lineamientos PRISMA. RESULTADOS: Un total de 42 artículos que describieron 39 estudios incluidos en la revisión, con la mayoría (n = 24; 57%) de calidad neutra. Treinta estudios implementaron un programa selectivo universal específico de trastornos de la conducta alimentaria y nueve implementaron intervenciones de estilo de vida más contenido para abordar la alimentación disfuncional. El metanálisis (n = 16 estudios) reveló una mejoría en los resultados relacionados con la imagen corporal en todos los estudios (DME 0,26 [IC95%: 0,00 a 0,53]); con un alto nivel de heterogeneidad (Î2 = 91,1%; p < 0,01). El metanálisis según el sexo reveló una mejora general en los resultados relacionados con la imagen corporal para las niñas (DME 0,40 [IC95%: 0,07 a 0,73]), pero no para los niños (DME 0,23 [IC95%: −0,24 a 0,70]). DISCUSIÓN: Al investigar las intervenciones tanto de los padres como de la enseñanza e incluir resultados como el control de peso y las conductas alimentarias de riesgo, se observó una tendencia hacia una reducción de los factores de riesgo de los trastornos de la conducta alimentaria. En concreto, mejoras en las variables relacionadas con la imagen corporal, especialmente en las niñas. Las direcciones futuras incluyen materiales de prevención de la alimentación disfuncional incorporados dentro de las intervenciones de estilo de vida existentes y la inclusión de muestras más diversas. PALABRAS CLAVE: Niños, trastornos de la conducta alimentaria y de la alimentación, alimentación disfuncional, prevención, imagen corporal, revisión sistemática, metanálisis.

RESUMO

Reduced energy intake is a major driver of weight loss and evidence suggests that physical activity, dietary, and sleep behaviours interact to influence energy intake. Energy restriction can be challenging to sustain. Therefore to improve intervention efficacy, evaluation of how changes in physical activity, diet, and sleep behaviours mediate reduced energy intake in adults with overweight/obesity who participated in a six-month multiple-behaviour-change weight loss intervention was undertaken. This was a secondary analysis of a 3-arm randomised controlled trial. Adults with body mass index (BMI) 25-40 kg/m2 were randomised to either: a physical activity and diet intervention; physical activity, diet, and sleep intervention; or wait-list control. Physical activity, dietary intake, and sleep was measured at baseline and six-months using validated measures. The two intervention groups were pooled and compared to the control. Structural equation modelling was used to estimate the mediated effects (AB Coefficient) of the intervention on total energy intake. One hundred and sixteen adults (70% female, 44.5y, BMI 31.7 kg/m2) were enrolled and 70% (n = 81) completed the six-month assessment. The significant intervention effect on energy intake at six-months (-1011 kJ/day, 95% CI -1922, -101) was partially mediated by reduced fat intake (AB = -761.12, 95% CI -1564.25, -53.74) and reduced consumption of energy-dense, nutrient-poor foods (AB = -576.19, 95% CI -1189.23, -97.26). In this study, reducing fat intake and consumption of energy-dense, nutrient-poor foods was an effective strategy for reducing daily energy intake in adults with overweight/obesity at six-months. These strategies should be explicitly targeted in future weight loss interventions.

RESUMO

BACKGROUND: This scoping review aims to describe the body of nutrition intervention and dietary assessment research undertaken with Khmer populations in Cambodia, as well as summarise the nutrition knowledge base and highlight priority areas for future research. METHODS: Five databases and the grey literature were searched, following PRISMA-ScR guidelines. Studies involving dietary assessment or nutrition interventions published after 1992 were identified using specific search terms and extracted to a customised data extraction table for categorisation and analysis. Study participants were Khmer people of any age and gender, living in rural or urban Cambodia. RESULTS: Of the 100 included studies, 58 were dietary assessment only studies, 24 were nutrition interventions only, and 18 studies involved both assessment of intake and an intervention. Sixty-eight percent of study populations were mothers and young children, of which 52 studies focused on children aged under 5 years. Nineteen interventions involved supplementation and six trialled fortification of rice or fish sauce. Anaemia was the most common nutrition condition studied (n = 17), followed by malnutrition (n = 15) and malnutrition risk factors (n = 11). General nutrition status was explored in 25 studies, and individual micronutrients that were studied included iron (n = 27), zinc (n = 6), vitamin A (n = 4) and thiamine (n = 3). CONCLUSIONS: Diet-related research in Khmer populations in Cambodia has predominantly focused on dietary assessment or evaluation of interventions aimed at reducing malnutrition and resolving micronutrient deficiencies. Areas identified as emerging needs included non-communicable diseases, the ageing population and non-iron deficiency anaemia.

RESUMO

BACKGROUND: Disordered eating habits, poor dietary intake and nutritional status, and altered body composition are highly prevalent among individuals with substance use disorders. This systematic review aimed to evaluate the efficacy of dietary interventions in adults with substance use disorders for illicit substances or illicit use of pharmaceutical substances. METHODS: Eight scientific databases were searched using predetermined text word and subject heading (MeSH) searches for experimental studies published up to March 2020 that evaluated interventions aiming to improve dietary intake in adults with substance use disorders for illicit substances or illicit use of pharmaceutical substances, which included dietary intake outcomes. RESULTS: Of 9299 articles identified, five studies were included. Three studies (60%) were conducted in outpatient/community clinic settings and two studies (40%) were conducted in inpatient/residential treatment centres. Dietary interventions ranged in duration from 5 weeks to 24 months. These included education and behaviour change advice for nutrition and other lifestyle behaviours (n = 3 studies), nutrition education and provision of healthy food choices within the residential treatment centre (n = 1 study), and polyunsaturated fatty acid supplementation (n = 1 study). Three studies (60%) reported small but significant change in one or more dietary outcome at post-intervention, including reductions in sweets, fast food or caffeine intake, as well as increases in fruit and vegetable intake. CONCLUSIONS: This review has identified a small number of studies, despite the strong evidence that dietary intervention is needed in substance use rehabilitation. More research is needed to determine the most effective intervention approaches for this group, including robust study designs.

RESUMO

PURPOSE: There is increasing interest in food addiction and its potential treatment. However, little is known about the characteristics of people seeking addictive eating treatment, which is important to develop appropriate treatment and referral pathways. The aim was to describe the characteristics of individuals seeking addictive eating treatment and examine differences between eligible participants who did and did not engage in treatment. METHODS: Participants interested in an addictive eating treatment were recruited to an online screening survey. The 55-item survey included demographic questions, body satisfaction; weight-loss attempts; the modified Yale Food Addiction Survey (mYFAS); the Binge Eating Scale and mental health outcomes (DASS-21). RESULTS: Individuals seeking addictive eating treatment (n = 309) were predominantly female (61%), from the obese BMI category (67%) and had accessed a range of services for weight loss (97%). Using multiple logistic regression, participants with higher mYFAS scores were more likely to engage in treatment (AOR 1.68; 95% CI 1.12-2.52), while participants with higher DASS total scores were less likely to engage in treatment (AOR 0.97; 95% CI 0.95-0.99). CONCLUSION: This study indicates considerable interest from consumers in seeking addictive eating treatment. Individuals who did not engage in treatment displayed higher mental health comorbidity, suggesting that higher mental health symptomatology may be a barrier to treatment. Future qualitative research is needed to provide an in-depth understanding of the reasons for seeking and engaging in addictive eating treatment, as well as to identify the optimal treatments and referral pathways. LEVEL OF EVIDENCE: Level IV.

RESUMO

The neuropeptide oxytocin has been associated with food intake and feeding behaviour. This systematic review aimed to investigate the impact of oxytocin on dietary intake and feeding behaviour in rodent studies. Six electronic databases were searched to identify published studies to April 2018. Preclinical studies in mice and rats were included if they reported: (1) a dietary measure (i.e. food or nutrient and/or behaviour (2) an oxytocin measure, and (3) relationship between the two measures. A total of 75 articles (n = 246 experiments) were included, and study quality appraised. The majority of studies were carried out in males (87%). The top three oxytocin outcomes assessed were: exogenous oxytocin administration (n = 126), oxytocin-receptor antagonist administration (n = 46) and oxytocin gene deletion (n = 29). Meta-analysis of exogenous studies in mice (3 studies, n = 43 comparisons) and rats (n = 8 studies, n = 82 comparisons) showed an overall decrease in food intake with maximum effect shown at 2 h post-administration.

RESUMO

BACKGROUND: To describe a-priori diet quality indices used in children and adolescents, appraise the validity and reliability of these indices, and synthesise evidence on the relationship between diet quality and physical and mental health, and growth-related outcomes. METHODS: Five electronic databases were searched until January 2019. An a-priori diet quality index was included if it applied a scoring structure to rate child or adolescent (aged 0-18-years) dietary intakes relative to dietary or nutrient guidelines. Diagnostic accuracy studies and prospective cohort studies reporting health outcomes were appraised using the Academy of Nutrition and Dietetics Quality Criteria Checklist. RESULTS: From 15,577 records screened, 128 unique paediatric diet quality indices were identified from 33 countries. Half of the indices' scores rated both food and nutrient intakes (n = 65 indices). Some indices were age specific: infant (< 24-months; n = 8 indices), child (2-12-years; n = 16), adolescent (13-18 years; n = 8), and child/adolescent (n = 14). Thirty-seven indices evaluated for validity and/or reliability. Eleven of the 15 indices which investigated associations with prospective health outcomes reported significant results, such as improved IQ, quality of life, blood pressure, body composition, and prevalence of metabolic syndrome. CONCLUSIONS: Research utilising diet quality indices in paediatric populations is rapidly expanding internationally. However, few indices have been evaluated for validity, reliability, or association with health outcomes. Further research is needed to determine the validity, reliability, and association with health of frequently utilised diet quality indices to ensure data generated by an index is useful, applicable, and relevant.

RESUMO

BACKGROUND: Severe mental illness (SMI) is thought to be associated with lower diet quality and adverse eating behaviours contributing towards physical health disparities. A rigorous review of the studies looking at dietary intake in psychotic disorders and bipolar disorder is lacking.AimsTo conduct a systematic, comprehensive evaluation of the published research on dietary intake in psychotic disorders and bipolar disorder. METHOD: Six electronic databases were searched for studies reporting on dietary intakes in psychotic disorders and bipolar disorder. Dietary-assessment methods, and dietary intakes, were systematically reviewed. Where possible, data was pooled for meta-analysis and compared with healthy controls. RESULTS: In total, 58 eligible studies were identified. People with SMI were found to have significantly higher dietary energy (mean difference 1332 kJ, 95% CI 487-2178 kJ/day, P = 0.002, g = 0.463) and sodium (mean difference 322 mg, 95% CI 174-490 mg, P < 0.001, g = 0.414) intake compared with controls. Qualitative synthesis suggested that higher energy and sodium intakes were associated with poorer diet quality and eating patterns. CONCLUSIONS: These dietary components should be key targets for preventative interventions to improve weight and other physical health outcomes in people with SMI.Declaration of interestS.B.T. and E.T. have clinical dietitian appointments within the South Eastern Sydney Local Health District and do not receive any further funding.

RESUMO

BACKGROUND: Electronic health (eHealth) interventions for children often rely on parent-reported child anthropometric measures. However, limited studies have assessed parental accuracy in reporting child height and weight via Web-based approaches. OBJECTIVE: The objective of this study was to determine the accuracy of parent-reported child height and weight, as well as body mass index and weight category that we calculated from these data. We also aimed to explore whether parent report was influenced by age, sex, weight status, or exposure to participation in a 12-week brief Web-based family lifestyle intervention. METHODS: This study was a secondary analysis of data from a 12-week childhood obesity pilot randomized controlled trial in families with children aged 4 to 11 years in Australia. We asked parents to report demographic information, including child height and weight, using an online survey before their child's height and weight were objectively measured by a trained research assistant at baseline and week 12. We analyzed data using the Lin concordance correlation coefficient (ρc, ranging from 0 [poor] to ±1 [perfect] concordance), Cohen kappa coefficient, and multivariable linear regression models. RESULTS: There were 42 families at baseline and 35 families (83%) at week 12. Overall, the accuracy of parent-reported child height was moderate (ρc=.94), accuracy of weight was substantial (ρc=.96), and accuracy of calculated body mass index was poor (ρc=.63). Parents underreported child height and weight, respectively, by 0.9 cm and 0.5 kg at baseline and by 0.2 cm and 1.6 kg after participating in a 12-week brief Web-based family lifestyle intervention. The overall interrater agreement of child body mass index category was moderate at baseline (κ=.59) and week 12 (κ=.54). The weight category calculated from 74% (n=31) and 70% (n=23) of parent-reported child height and weight was accurate at baseline and week 12, respectively. Parental age was significantly (95% CI -0.52 to -0.06; P=.01) associated with accuracy of reporting child height. Child age was significantly (95% CI -2.34 to -0.06; P=.04) associated with reporting of child weight. CONCLUSIONS: Most Australian parents were reasonably accurate in reporting child height and weight among a group of children aged 4 to 11 years. The weight category of most of the children when calculated from parent-reported data was in agreement with the objectively measured data despite the body mass index calculated from parent-reported data having poor concordance at both time points. Online parent-reported child height and weight may be a valid method of collecting child anthropometric data ahead of participation in a Web-based program. Future studies with larger sample sizes and repeated measures over time in the context of eHealth research are warranted. Future studies should consider modeling the impact of calibration equations applied to parent-reported anthropometric data on study outcomes.

RESUMO

OBJECTIVE: CVD is a leading cause of mortality and morbidity, and nutrition is an important lifestyle factor. The aim of the present systematic review was to synthesise the literature relating to knowledge translation (KT) of dietary evidence for the prevention and treatment of CVD into practice in populations with or at high risk of CVD. DESIGN: A systematic search of six electronic databases (CINAHL, Cochrane, EMBASE, MEDLINE, PsycINFO and Scopus) was performed. Studies were included if a nutrition or dietary KT was demonstrated to occur with a relevant separate measureable outcome. Quality was assessed using a tool adapted from two quality checklists. SUBJECTS: Population with or at high risk of CVD or clinicians likely to treat this population. RESULTS: A total of 4420 titles and abstracts were screened for inclusion, with 354 full texts retrieved to assess inclusion. Forty-three articles were included in the review, relating to thirty-five separate studies. No studies specifically stated their aim to be KT. Thirty-one studies were in patient or high-risk populations and four targeted health professionals. Few studies stated a theory on which the intervention was based (n 10) and provision of instruction was the most common behaviour change strategy used (n 26). CONCLUSIONS: KT in nutrition and dietary studies has been inferred, not stated, with few details provided regarding how dietary knowledge is translated to the end user. This presents challenges for implementation by clinicians and policy and decision makers. Consequently a need exists to improve the quality of publications in this area.

RESUMO

The Yale Food Addiction Scale (YFAS) is a widely used tool to assess the behavioural indicators of addictive-like eating. No studies, however, have used a longitudinal design to determine whether these addictive-like eating behaviours are a stable or transient phenomenon in a community-based population. This study aimed to evaluate whether food addiction Diagnosis and Symptom scores as assessed by the YFAS remain stable over 18-months in a non-clinical population. Young adults aged 18-35 years were recruited from the community to a web-based survey in 2013. The survey included demographics, anthropometrics and the YFAS. Participants who volunteered to be recontacted for future research were invited to complete the same survey 18-months later. The YFAS scoring outputs Diagnosis and Symptom scores were tested for agreement and reliability between the two time points. Of the 303 participants who completed the original survey and agreed to be recontacted, 69 participants (22.8% of those recontacted, 94% female, 67% normal weight at baseline) completed the 18-month follow-up survey. At baseline, thirteen participants met the YFAS predefined criteria for Diagnosis, while eleven participants met these criteria at the 18-month follow-up. YFAS Diagnosis was found to have moderate agreement [K = .50, 95% CI (.23, .77)] between the two time points while Symptom scores had good agreement [K = .70, 95% CI (.54, .83)]. Intraclass correlation coefficients were interpreted as moderate over the 18-month period for both the Diagnosis [ICC = .71, 95% CI (.45, .88)] and Symptom scores [ICC = .72, 95% CI (.58, .82)]. YFAS assessed food addiction Diagnosis and Symptom scores were found to be relatively stable over 18-months in a non-clinical population of predominantly female, young adults. Future research is required to determine the impact of behavioural weight loss interventions on YFAS assessed addictive-like eating.

RESUMO

PURPOSE: Few efficacious child obesity interventions have been converted into ongoing community programs in the after-school setting. The aim of this study was to evaluate the impact of phase 2 of the Back to Basics cooking club on dietary behaviours and fruit and vegetable variety in a population at risk of obesity at a low income school with > 10% indigenous population. METHODS: Baseline and 3-month dietary intake and social cognitive theory (SCT) constructs were collected in 51 children, mean age 9 years, 61% female. McNemar tests were used for comparison of proportions between categorical variables. Cohen's d was used to compare effect sizes across different measures. RESULTS: Consumption of one or more fruit servings per day significantly increased from 41% to 67% (P = 0.02, d = 0.13) and there was a trend for increasing the weekly variety of fruit and vegetables. The SCT constructs assessed within the current study improved significantly (P < 0.05), with moderate to large effect sizes (d = 0.33-0.78). CONCLUSION: This study documents that a previous efficacious healthy lifestyle program can be adapted for use as an obesity prevention program addressing improvements in vegetable and fruit intakes in a low income community with a relatively high indigenous population.

RESUMO

BACKGROUND: Diet quality tools provide researchers with brief methods to assess the nutrient adequacy of usual dietary intake. This study describes the development and validation of a pediatric diet quality index, the Australian Recommended Food Scores for Pre-schoolers (ARFS-P), for use with children aged two to five years. METHODS: The ARFS-P was derived from a 120-item food frequency questionnaire, with eight sub-scales, and was scored from zero to 73. Linear regressions were used to estimate the relationship between diet quality score and nutrient intakes, in 142 children (mean age 4 years) in rural localities in New South Wales, Australia. RESULTS: Total ARFS-P and component scores were highly related to dietary intake of the majority of macronutrients and micronutrients including protein, ß-carotene, vitamin C, vitamin A. Total ARFS-P was also positively related to total consumption of nutrient dense foods, such as fruits and vegetables, and negatively related to total consumption of discretionary choices, such as sugar sweetened drinks and packaged snacks. CONCLUSION: ARFS-P is a valid measure that can be used to characterise nutrient intakes for children aged two to five years. Further research could assess the utility of the ARFS-P for monitoring of usual dietary intake over time or as part of clinical management.
