Sugar-Sweetened Beverages and Adverse Human Health Outcomes: An Umbrella Review of Meta-Analyses of Observational Studies.

Our aim was to conduct an umbrella review of evidence from meta-analyses of observational studies investigating the link between sugar-sweetened beverage consumption and human health outcomes. Using predefined evidence classification criteria, we evaluated evidence from 47 meta-analyses encompassing 22,055,269 individuals. Overall, 79% of these analyses indicated direct associations between greater sugar-sweetened beverage consumption and higher risks of adverse health outcomes. Convincing evidence (class I) supported direct associations between sugar-sweetened beverage consumption and risks of depression, cardiovascular disease, nephrolithiasis, type 2 diabetes mellitus, and higher uric acid concentrations. Highly suggestive evidence (class II) supported associations with risks of nonalcoholic fatty liver disease and dental caries. Out of the remaining 40 meta-analyses, 29 were graded as suggestive or weak in the strength of evidence (classes III and IV), and 11 showed no evidence (class V). These findings inform and provide support for population-based and public health strategies aimed at reducing sugary drink consumption for improved health.

Metabolic syndrome risk prediction in an Australian sample with first-episode psychosis using the psychosis metabolic risk calculator: A validation study.

OBJECTIVE: To examine the accuracy and likely clinical usefulness of the Psychosis Metabolic Risk Calculator (PsyMetRiC) in predicting up-to six-year risk of incident metabolic syndrome in an Australian sample of young people with first-episode psychosis. METHOD: We conducted a retrospective study at a secondary care early psychosis treatment service among people aged 16-35 years, extracting relevant data at the time of antipsychotic commencement and between one-to-six-years later. We assessed algorithm accuracy primarily via discrimination (C-statistic), calibration (calibration plots) and clinical usefulness (decision curve analysis). Model updating and recalibration generated a site-specific (Australian) PsyMetRiC version. RESULTS: We included 116 people with baseline and follow-up data: 73% male, mean age 20.1 years, mean follow-up 2.6 years, metabolic syndrome prevalence 13%. C-statistics for both partial- (C = 0.71, 95% CI 0.64-0.75) and full-models (C = 0.72, 95% CI 0.65-0.77) were acceptable; however, calibration plots demonstrated consistent under-prediction of risk. Recalibration and updating led to slightly improved C-statistics, greatly improved agreement between observed and predicted risk, and a narrow window of likely clinical usefulness improved significantly. CONCLUSION: An updated and recalibrated PsyMetRiC model, PsyMetRiC-Australia, shows promise. Validation in a large sample is required to confirm its accuracy and clinical usefulness for the Australian population.

Prevalence of food insecurity in people with major depression, bipolar disorder, and schizophrenia and related psychoses: A systematic review and meta-analysis.

People with severe mental illness (SMI), such as major depression, bipolar disorder, and schizophrenia, experience numerous risk factors that may predispose them to food insecurity; however, the prevalence of food insecurity and its effects on health are under-researched in this population group. This systematic review and meta-analysis aimed to describe the prevalence and correlates of food insecurity in people with SMI. A comprehensive electronic search was conducted up to March 2021. Random effects meta-analysis was employed to determine the prevalence of food insecurity in SMI, and odds ratio (OR) of food insecurity in people with SMI compared to non-psychiatric controls/general population. Twenty-nine unique datasets (31 publications) were included. Prevalence estimate of food insecurity in people with SMI was 40% (95% CI 29-52%, I2 = 99.7%, N = 27). People with SMI were 2.71 (95% CI 1.72-3.25) times more likely to report food insecurity than the comparator group (Z = 11.09, p < 0.001, I2 = 95%, N = 23). The odds of food insecurity in SMI were higher in high/high-middle income countries compared to low/low-middle income countries, likely due to the high food insecurity rates in the general population of lower income countries. There was no difference in food insecurity rates by diagnosis. Food insecurity should be a consideration for health professionals working with community-dwelling people with SMI.

The resting metabolic rate of people with severe mental illness: a systematic review and meta-analysis.

People with severe mental illness (SMI), including schizophrenia and related psychoses and bipolar disorder, are at greater risk for obesity compared with people without mental illness. An altered resting metabolic rate (RMR) may be a key driving factor; however, published studies have not been systematically reviewed. This systematic review and meta-analysis aimed to determine whether the RMR of people with SMI assessed by indirect calorimetry differs from (i) controls, (ii) predictive equations and (iii) after administration of antipsychotic medications. Five databases were searched from database inception to March 2022. Thirteen studies providing nineteen relevant datasets were included. Study quality was mixed (62 % considered low quality). In the primary analysis, RMR in people with SMI did not differ from matched controls (n 2, standardised mean difference (SMD) = 0·58, 95 % CI -1·01, 2·16, P = 0·48, I2 = 92 %). Most predictive equations overestimated RMR. The Mifflin-St. Jeor equation appeared to be most accurate (n 5, SMD = -0·29, 95 % CI -0·73, 0·14, P = 0·19, I2 = 85 %). There were no significant changes in RMR after antipsychotic administration (n 4, SMD = 0·17, 95 % CI -0·21, 0·55, P = 0·38, I2 = 0 %). There is little evidence to suggest there is a difference in RMR between people with SMI and people without when matched for age, sex, BMI and body mass, or that commencement of antipsychotic medication alters RMR.

Exploring the role of dietitians in mental health services and the perceived barriers and enablers to service delivery: A cross-sectional study.

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.

How should we judge edible oils and fats? An umbrella review of the health effects of nutrient and bioactive components found in edible oils and fats.

Dietary guidelines for many Western countries base their edible oil and fat recommendations solely on saturated fatty acid content. This study aims to demonstrate which nutritional and bioactive components make up commonly consumed edible oils and fats; and explore the health effects and strength of evidence for key nutritional and bioactive components of edible oils. An umbrella review was conducted in several stages. Food composition databases of Australia and the United States of America, and studies were examined to profile nutrient and bioactive content of edible oils and fats. PUBMED and Cochrane databases were searched for umbrella reviews, systematic literature reviews of randomized controlled trials or cohort studies, individual randomized controlled trials, and individual cohort studies to examine the effect of the nutrient or bioactive on high-burden chronic diseases (cardiovascular disease, type 2 diabetes mellitus, obesity, cancer, mental illness, cognitive impairment). Substantial systematic literature review evidence was identified for fatty acid categories, tocopherols, biophenols, and phytosterols. Insufficient evidence was identified for squalene. The evidence supports high mono- and polyunsaturated fatty acid compositions, total biophenol content, phytosterols, and possibly high α-tocopherol content as having beneficial effects on high-burden health comes. Future dietary guidelines should use a more sophisticated approach to judge edible oils beyond saturated fatty acid content.

Effectiveness of nutrition and dietary interventions for people with serious mental illness: systematic review and meta-analysis.

OBJECTIVE: To review recent published trials of nutrition and dietary interventions for people with serious mental illness; to assess their effectiveness in improving metabolic syndrome risk factors. STUDY DESIGN: Systematic review and meta-analysis of randomised and non-randomised controlled trials of interventions with a nutrition/diet-related component delivered to people with serious mental illness, published 1 January 2010 - 6 September 2021. Primary outcomes were weight, body mass index (BMI), and waist circumference. Secondary outcomes were total serum cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, triglyceride, and blood glucose levels. DATA SOURCES: MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL databases. In addition, reference lists of relevant publications were examined for further additional studies. DATA SYNTHESIS: Twenty-five studies encompassing 26 intervention arms were included in our analysis. Eight studies were at low or some risk of bias, seventeen were deemed to be at high risk. Eight of seventeen intervention arms found statistically significant intervention effects on weight, ten of 24 on BMI, and seven of seventeen on waist circumference. The pooled effects of nutrition interventions on metabolic syndrome risk factors were statistically non-significant. However, we identified small size effects on weight for interventions delivered by dietitians (five studies; 262 intervention, 258 control participants; standardised mean difference [SMD], -0.28; 95% CI, -0.51 to -0.04) and interventions consisting of individual sessions only (three studies; 141 intervention, 134 control participants; SMD, -0.30; 95% CI, -0.54 to -0.06). CONCLUSIONS: We found only limited evidence for nutrition interventions improving metabolic syndrome risk factors in people with serious mental illness. However, they may be more effective when delivered on an individual basis or by dietitians. PROSPERO REGISTRATION: CRD42021235979 (prospective).

Keeping our staff in mind: Dietary results of a lifestyle intervention targeting mental health staff.

ISSUES ADDRESSED: 1) Describe the dietary intake of mental health staff within South Eastern Sydney Local Health District and 2) Evaluate the impact of an individualised staff lifestyle program on the following nutrition parameters; (i) energy, (ii) core food groups and (iii) discretionary foods. METHODS: This was a pragmatic single-arm intervention study, conducted for all staff working in a public mental health service, in Sydney, Australia. A five-session individualised lifestyle intervention delivered over 5 weeks incorporated nutritional counselling delivered by a dietitian. Participants were assessed at baseline, following the intervention, and at follow-up using diet history to assess dietary intake. RESULTS: Eighty-eight staff completed the dietary intervention and follow-up. An intake of core food groups significantly below national recommendations was reported for total vegetables (-1.75 ± 0.14 serves, P < .001), fruit (-0.29 ± 0.11 serves, P = .01), grains (-1.25 ± 0.20 serves, P < .001) and dairy servings (-1.00 ± 1.08 serves, P < .001), and protein-based foods were significantly above national recommendations (0.2 ± 0.09 serves, P = .03). At completion of the program, energy from discretionary foods was reduced by 460 kJ (95% CI -635 to -285, P < .001), and the serves of total vegetables (0.91 serves, 95% CI 0.59-1.22, P < .001) and dairy (0.31 serves, 95% CI 0.11-0.50, P < .001) were increased significantly. CONCLUSIONS: A workplace-based well-being program for staff working in the mental health setting coincided with dietary improvements. SO WHAT: Mental health staff can act as positive role models for clients to promote developing positive physical health behaviours.

Prevalence and correlates of food insecurity in community-based individuals with severe mental illness receiving long-acting injectable antipsychotic treatment.

People with severe mental illness (SMI) have numerous risk factors that may predispose them to food insecurity (FI); however, the prevalence of FI and its effects on health are under-researched in this population. The present study aimed to describe the prevalence of FI and its relationship to lifestyle factors in people with SMI. This cross-sectional study recruited people with SMI receiving long-acting injectable (LAI) antipsychotic medication from community services at three sites in Sydney, Australia. Assessments were completed on physical health and lifestyle factors. χ2 Tests, independent-samples t tests and binary logistic regression analyses were calculated to examine relationships between lifestyle factors and FI. In total, 233 people completed the assessments: 154 were males (66 %), mean age 44·8 (sd 12·7) years, and the majority (70 %) had a diagnosis of schizophrenia. FI was present in 104 participants (45 %). People with FI were less likely to consume fruits (OR 0·42, 95 % CI 0·24, 0·74, P = 0·003), vegetables (OR 0·39, 95 % CI 0·22, 0·69, P = 0·001) and protein-based foods (OR 0·45, 95 % CI 0·25, 0·83, P = 0·011) at least once daily, engaged in less moderate to vigorous physical activity (min) (OR 0·997, 95 % CI 0·993, 1·000, P = 0·044), and were more likely to smoke (OR 1·89, 95 % CI 1·08, 3·32, P = 0·026). FI is highly prevalent among people with SMI receiving LAI antipsychotic medications. Food-insecure people with SMI engage in less healthy lifestyle behaviours, increasing the risk of future non-communicable disease.

The Effects of Dietary Improvement on Symptoms of Depression and Anxiety: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: Poor diet can be detrimental to mental health. However, the overall evidence for the effects of dietary interventions on mood and mental well-being has yet to be assessed. We conducted a systematic review and meta-analysis examining effects of dietary interventions on symptoms of depression and anxiety. METHODS: Major electronic databases were searched through March 2018 for all randomized controlled trials of dietary interventions reporting changes in symptoms of depression and/or anxiety in clinical and nonclinical populations. Random-effects meta-analyses were conducted to determine effect sizes (Hedges' g with 95% confidence intervals [CI]) for dietary interventions compared with control conditions. Potential sources of heterogeneity were explored using subgroups and meta-regression analyses. RESULTS: Results: Sixteen eligible randomized controlled trials (published in English) with outcome data for 45,826 participants were included; the majority of which examined samples with nonclinical depression (n = 15 studies). Nonetheless, dietary interventions significantly reduced depressive symptoms (g = 0.162, 95% CI = 0.055 to 0.269, p = 0.003). Similar effects were observed among high-quality trials (g = 0.171, 95% C.I.=0.057 to 0.286, p=0.003) and when compared with both inactive (g = 0.114, 95% C.I.=0.008 to 0.219, p=0.035) and active controls (g = 0.224, 95% C.I.= 0.052 to 0.397, p = 0.011). No effect of dietary interventions was observed for anxiety (k = 11, n = 2270, g = 0.085, 95% C.I. = -0.031 to 0.202, p=0.151). Studies with female samples observed significantly greater benefits from dietary interventions, for symptoms of both depression and anxiety. CONCLUSIONS: Dietary interventions hold promise as a novel intervention for reducing symptoms of depression across the population. Future research is required to determine the specific components of dietary interventions that improve mental health, explore underlying mechanisms, and establish effective schemes for delivering these interventions in clinical and public health settings.

Dietary intake of people with severe mental illness: systematic review and meta-analysis.

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.

Expanding collaborative care: integrating the role of dietitians and nutrition interventions in services for people with mental illness.

OBJECTIVE: This article aims to draw mental health clinicians' attention to the connections between nutrition and mental health, and the roles that Accredited Practising Dietitians play in improving mental and physical health through dietary change. METHODS: Selective narrative review. RESULTS: Unhealthy dietary practices are common in high prevalence and severe mental illness. Epidemiological evidence demonstrates that nutrients and dietary patterns impact on mental health. In addition, poor physical health is well documented in people with mental illness and the greatest contributor to the mortality gap. Dietary intervention studies demonstrate improved mental and physical health outcomes. Accredited Practising Dietitians translate nutrition science into practical advice to improve the nutritional status of patients with mental illness, and prevent and manage comorbidities in a variety of care settings. CONCLUSIONS: Medical Nutrition Therapy offers opportunities to improve the physical and mental health of people living with mental illness.

Solving a weighty problem: systematic review and meta-analysis of nutrition interventions in severe mental illness.

BACKGROUND: Nutrition interventions would appear fundamental for weight management and cardiometabolic risk reduction in people experiencing severe mental illness (SMI). Comprehensive evaluation of nutrition interventions is lacking. AIMS: To subject randomised controlled trials of nutrition interventions in people with SMI to systematic review and meta-analysis, and to measure anthropometric and biochemical parameters and nutritional intake. METHOD: An electronic database search identified trials with nutrition intervention components. Trials were pooled for meta-analysis. Meta-regression analyses were performed on anthropometric moderators. RESULTS: Interventions led to significant weight loss (19 studies), reduced body mass index (17 studies), decreased waist circumference (10 studies) and lower blood glucose levels (5 studies). Dietitian-led interventions (6 studies) and studies delivered at antipsychotic initiation (4 studies) had larger effect sizes. CONCLUSIONS: Evidence supports nutrition interventions as standard care in preventing and treating weight gain among people experiencing SMI.

A nutrition intervention is effective in improving dietary components linked to cardiometabolic risk in youth with first-episode psychosis.

Severe mental illness is characterised by a 20-year mortality gap due to cardiometabolic disease. Poor diet in those with severe mental illness is an important and modifiable risk factor. The present study aimed to (i) examine baseline nutritional intake in youth with first-episode psychosis (FEP), (ii) evaluate the feasibility and acceptability of nutritional intervention early in FEP and (iii) to evaluate the effectiveness of early dietary intervention on key nutritional end points. Participants were recruited over a 12-month period from a community-based programme specifically targeting young people aged 15-25 years with newly diagnosed FEP. Individual dietetic consultations and practical group sessions were offered as part of a broader lifestyle programme. Dietary assessments were conducted before and at the end of the 12-week intervention. Participants exceeded recommended energy and Na intakes at baseline. Retention within the nutrition intervention was 67 %, consistent with other interventions offered to FEP clients. There was a 47 % reduction in discretionary food intake (-94 g/d, P<0·001) and reductions in daily energy (-24 %, P<0·001) and Na (-26 %, P<0·001) intakes. Diet quality significantly improved, and the mean change was 3·6 (95 % CI 0·2, 6·9, P<0·05), although this finding was not significant after Bonferroni's correction. Increased vegetable intake was the main factor contributing to improved diet quality. Nutrition intervention delivered shortly after initiation of antipsychotic medication is feasible, acceptable and effective in youth with FEP. Strategies to prevent weight gain and metabolic decline will contribute to prevent premature cardiometabolic disease in this vulnerable population.

Implementation of a lifestyle and life-skills intervention to prevent weight-gain and cardiometabolic abnormalities in young people with first-episode psychosis as part of routine care: The Keeping the Body in Mind program.

OBJECTIVES: In 2013, a cluster-controlled pilot study found the 12-week Keeping the Body in Mind (KBIM) lifestyle and life skills intervention was able to prevent weight gain in a small sample of youth experiencing first-episode psychosis (FEP) with fewer than 4 weeks of antipsychotic exposure. This study aims to evaluate the effectiveness of KBIM as routine care on anthropometry and metabolic biochemistry in a larger sample of youth with FEP across three community mental health services. METHOD: This retrospective chart audit was conducted on youth with FEP, prescribed a therapeutic dose of antipsychotic medication, and who engaged with KBIM between 2015 and 2019. Primary outcomes were weight and waist circumference. Secondary outcomes were blood pressure, blood glucose, and blood lipids. Outcomes were collected in at baseline and at 12 weeks. Data on program engagement were obtained from the participant's medical file. RESULTS: One-hundred and eighty-two people met inclusion criteria, and up to 134 people had baseline and 12-week data on one or more outcome. Mean number of sessions attended was 11.1 (SD = 7.3). Increases in weight and waist circumference were limited to 1.5 kg (SD = 5.3, t(133) = 3.2, p = .002) and 0.7 cm (SD = 5.8, t(109) = 1.2, p = .23) respectively. Eighty-one percent of participants did not experience clinically significant weight gain (>7% of baseline weight). There were no significant changes in blood pressure or metabolic biochemistry. CONCLUSION: The prevention of substantial gains in weight and waist circumference observed in the initial pilot study was maintained with implementation of KBIM as part of routine clinical care for youth with FEP.

Evaluation of a community-based brief intervention service for youth in crisis with suicidal ideation or self-harm.

AIM: To evaluate the implementation of a mixed virtual and in-person brief intervention for young people, aged 12-25 years, presenting to a large urban mental health service in crisis with suicidal ideation and/or self-harm. METHODS: A pragmatic, real-world evaluation was conducted on the Youth Brief Intervention Service between June 2021 (inception) and October 2022. Service users were offered four sessions over an approximate one-month period. Sessions focused on distress tolerance, safety plans and support systems. Implementation outcomes related to service uptake, retention, fidelity of the model and service user experience. Effectiveness outcomes were measured pre-post and included mental health-related hospital service utilization (primary outcome), functioning, mental health status, self-harm, suicidal ideation and quality of life. RESULTS: Of the 136 young people referred to the Youth Brief Intervention Service, 99 were accepted with 17 disengaging before the first session. Eighty percent of people who commenced, completed the package of care. Young persons' and parent/carers experience of service was high (97% and 88%, respectively). Mental health-related emergency department presentations and inpatient days decreased from 3 months pre-intake to 3 months post-intake (42 vs. 7 presentations, X2 = 25.3, p < .001; 11 vs. 0 inpatient days, X2 = 9.1, p = .01). There were significant improvements in mental health status, days engaging in self-harm, general health and functioning and quality of life. CONCLUSIONS: The Youth Brief Intervention Service is feasible, acceptable, subjectively beneficial and coincided with less mental health-related emergency department presentations and inpatient days, and improved mental health status and behaviour.

Food insecurity in adults with severe mental illness living in Northern England: A co-produced cross-sectional study.

AIM: This study aimed to explore food insecurity prevalence and experiences of adults with severe mental illness living in Northern England. METHODS: This mixed-methods cross-sectional study took place between March and October 2022. Participants were adults with self-reported severe mental illness living in Northern England. The survey included demographic, health, and financial questions. Food insecurity was measured using the US Department of Agriculture Adult Food Security measure. Quantitative data were analysed using descriptive statistics and binary logistic regression; and qualitative data using content analysis. RESULTS: In total, 135 participants completed the survey, with a mean age of 44.7 years (SD: 14.1, range: 18-75 years). Participants were predominantly male (53.3%), white (88%) and from Yorkshire (50.4%). The food insecurity prevalence was 50.4% (n = 68). There was statistical significance in food insecurity status by region (p = 0.001); impacts of severe mental illness on activities of daily living (p = 0.02); and the Covid pandemic on food access (p < 0.001). The North West had the highest prevalence of food insecurity (73.3%); followed by the Humber and North East regions (66.7%); and Yorkshire (33.8%). In multivariable binary logistic regression, severe mental illness' impact on daily living was the only predictive variable for food insecurity (odds ratio = 4.618, 95% confidence interval: 1.071-19.924, p = 0.04). CONCLUSION: The prevalence of food insecurity in this study is higher than is reported in similar studies (41%). Mental health practitioners should routinely assess and monitor food insecurity in people living with severe mental illness. Further research should focus on food insecurity interventions in this population.

Irritable bowel syndrome and mental health comorbidity - approach to multidisciplinary management.

Irritable bowel syndrome (IBS) affects 5-10% of the global population. Up to one-third of people with IBS also experience anxiety or depression. Gastrointestinal and psychological symptoms both drive health-care use in people with IBS, but psychological comorbidity seems to be more important for long-term quality of life. An integrated care approach that addresses gastrointestinal symptoms with nutrition and brain-gut behaviour therapies is considered the gold standard. However, best practice for the treatment of individuals with IBS who have a comorbid psychological condition is unclear. Given the rising prevalence of mental health disorders, discussion of the challenges of implementing therapy for people with IBS and anxiety and depression is critical. In this Review, we draw upon our expertise in gastroenterology, nutrition science and psychology to highlight common challenges that arise when managing patients with IBS and co-occurring anxiety and depression, and provide recommendations for tailoring clinical assessment and treatment. We provide best practice recommendations, including dietary and behavioural interventions that could be applied by non-specialists and clinicians working outside an integrated care model.

Relationship between discretionary food intake and sex, body image, health, and geographical remoteness among Indigenous Australian adolescents.

AIM: Determine the discretionary energy intake of Indigenous Australian adolescents and its relationship with sex, body image, health, and geographical remoteness. METHODS: Cross-sectional data from the 2012 to 2013 National Aboriginal and Torres Strait Islander Nutrition and Physical Activity Survey (n = 264, 15-17 years). Dietary data were collected using an Automated Multiple-Pass Method, anthropometric data by trained interviewers; self-perceived measures of body weight, level of satisfaction with current weight, and self-assessed health were self-reported. General linear models were used to investigate predictors. RESULTS: Discretionary energy intake contributed 35.4% and 54.2% of total energy intake for males and females, respectively, primarily from the sub-groups: soft drinks; pastries; potatoes; sugar, honey and syrups; cordials; and potato snacks. Discretionary energy intake was associated with higher energy intake (p < 0.001) and self-perceived body weight (p = 0.022), while sex had significant interactions with self-assessed health (psex  = 0.005), satisfaction with current weight (psex  < 0.001), and geographical remoteness (psex  = 0.007). Contribution of discretionary energy intake to total energy intake was greatest for males with an increased risk of metabolic complications (50% vs. 37%; p > 0.05), those who perceived themselves to be overweight (56% vs. 27%; p < 0.001), and those who were dissatisfied with their weight (56% vs. 19%; p < 0.001), compared to females. No differences were found by dieting status, risk of metabolic complications, and under-reporting of energy intake. CONCLUSIONS: Discretionary energy intake was excessive among Indigenous Australian adolescents and had relationships with self-perceived health, weight satisfaction, and geographical remoteness, which was moderated by sex. To successfully reduce discretionary food intake among Indigenous Australian adolescents, further research is required to develop sex specific and culturally appropriate strategies.
