Introduction: People with obesity are vulnerable to eating disorders. It has been suggested that screening for eating disorder risk be part of obesity care. However, it is unclear what current practice entails., Objective: To explore considerations of eating disorder risk during treatment of obesity, including assessment and intervention strategies used in clinical practice., Materials and Methods: An online (REDCap) cross-sectional survey was distributed to health professionals working with individuals with obesity in Australia through professional societies and social media. The survey had three sections: 1. Characteristics of Clinician/Practice, 2. Current Practice, 3. Attitudes. Data were summarised using descriptive statistics and free-text comments were independently coded in duplicate to identify themes., Results: 59 health professionals completed the survey. Most were dietitians (n = 29), identified as women (n = 45) and worked within a public hospital (n = 30) and/or private practice (n = 29). Overall, 50 respondents reported assessing for eating disorder risk. Most reported that having a history of, or risk factors of eating disorders should not preclude obesity care but emphasised the importance of treatment modification including using a patient-centred approach involving a multidisciplinary team and promoting healthy eating behaviours, with less emphasis on calorie restriction or bariatric surgery. Management approaches did not differ for those with eating disorder risk factors or a diagnosed eating disorder. Clinicians identified the need for additional training and clear referral pathways., Conclusion: Individualised care, balancing models of care for eating disorders and obesity and further access to training and services will be important in improving care of patients with obesity., (Copyright © 2023 Asia Oceania Association for the Study of Obesity.

Background: Intermittent energy restriction (IER) has shown early success in adolescents with obesity, however efficacy trials are needed. This study aims to determine if IER results in lower body mass index (BMI) z-score after 52 weeks in metabolically unhealthy adolescents with obesity compared with continuous energy restriction (CER)., Methods/design: This is a prospective, randomised, multi-centre trial conducted in tertiary care settings, with three phases: jumpstart (weeks 0-4); intensive intervention (weeks 5-16); continued intervention and/or maintenance (weeks 17-52). During the jumpstart phase, all participants follow a very low energy diet (∼800kcal/3350kJ/day), then transition to their allocated intervention: IER or CER. IER involves three energy-restricted days/week, consuming one-third of daily energy requirements (∼600-700kcal/2500-2950kJ/day), and four days/week of a healthy meal plan. The CER, which is current standard care, has individually tailored energy prescription based on age and sex (13-14years, 1430-1670kcal/6000-7000kJ/day; 15-17years, 1670-1900kcal/7000-8000kJ/day). The study will recruit 186 (93 per arm) treatment-seeking adolescents aged 13-17years with obesity and at least one metabolic co-morbidity. The primary outcome is change in BMI z-score at 52 weeks. Secondary outcomes are changes at 4, 16 and 52 weeks in: body composition; diet quality, food choices and food patterns; cardio-metabolic risk factors; physical activity and sedentary behaviour; sleep and psycho-behavioural measures., Discussion: This study challenges existing clinical paradigms that CER is the only method for weight management in metabolically unhealthy adolescents. If successful, IER may offer an alternate medical nutrition therapy approach for those seeking treatment in tertiary settings., Clinical Trial Registration Number: ACTRN12617001630303., (Copyright © 2019.

Background: Intermittent energy restriction (IER) is an effective obesity management strategy in adults., Objective: The aim of this study was to investigate the feasibility, effectiveness, and acceptability of IER in adolescents (aged 12-17 y) with obesity [adult equivalent body mass index (BMI; kg/m2) ≥30]., Methods: During weeks 1-12 participants followed an IER dietary plan consisting of a very-low-energy diet (VLED) 3 d/wk (500-600 kcal/d) and an eating plan consistent with national dietary guidelines 4 d/wk. For weeks 13-26 participants chose to continue with 1-3 VLED d/wk or follow a prescriptive eating plan. Primary outcomes were feasibility and change in BMI expressed as a percentage of the 95th percentile (BMI %95th percentile) at 12 wk. Secondary outcomes were diet acceptability, body composition, cardiometabolic risk, vascular structure and function, quality of life (Pediatric Quality of Life Inventory), and eating behaviors [Dutch Eating Behavior Questionnaire (DEBQ-C)]. Linear mixed models were used to assess change in outcome measures., Results: Of 45 adolescents invited to participate, 30 adolescents (mean ± SD age: 14.5 ± 1.4 y, female n = 25) with a median BMI of 34.9 (range: 27.7-52.4) were recruited. At 12 wk, 23 participants chose to continue with the VLED 2-3 d/wk, and 21 completed the study, indicating the feasibility of IER. Consistent with intention-to-treat analysis, BMI %95th percentile was reduced at 12 wk (difference in estimated marginal means ± SEMs: -5.6 ± 1.1, P < 0.001) and 26 wk (-5.1 ± 1.9, P = 0.013) compared with baseline. Plasma triglycerides were reduced at 26 wk from baseline (-0.33 ± 0.12 mmol/L, P = 0.03). Body fat percentage reduced between 12 and 26 wk (-1.57% ± 0.76%, P = 0.05). Carotid intima-media thickness (CIMT) (-0.06 ± 0.01 mm, P < 0.001) and flow-mediated dilation (absolute increase 0.44% ± 0.11%, P = 0.001) improved between baseline and 12 wk, with reduced CIMT maintained at 26 wk (P < 0.001). DEBQ-C and Pediatric Quality of Life Inventory scores improved throughout the intervention. Nineteen adolescents completed an acceptability interview, rating IER as easy and pleasant to follow (mean ± SD: +2.1 ± 1.2; +1.9 ± 1.2, respectively) on a Likert scale from -4 to +4., Conclusion: IER is a feasible, effective, and acceptable intervention in adolescents with obesity achieving reductions in BMI and cardiovascular disease risk.

Background: Gestational weight gain within the recommended range produces optimal pregnancy outcomes, yet many women exceed the guidelines. Official recommendations to increase energy intake by ∼ 1000 kJ/day in pregnancy may be excessive., Objective: To determine by metaanalysis of relevant studies whether greater increments in energy intake from early to late pregnancy corresponded to greater or excessive gestational weight gain., Data Sources: We systematically searched electronic databases for observational and intervention studies published from 1990 to the present. The databases included Ovid Medline, Cochrane Library, Excerpta Medica DataBASE (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Science Direct. In addition we hand-searched reference lists of all identified articles., Study Eligibility Criteria: Studies were included if they reported gestational weight gain and energy intake in early and late gestation in women of any age with a singleton pregnancy. Search also encompassed journals emerging from both developed and developing countries., Study Appraisal and Synthesis Methods: Studies were individually assessed for quality based on the Quality Criteria Checklist obtained from the Evidence Analysis Manual: Steps in the academy evidence analysis process. Publication bias was plotted by the use of a funnel plot with standard mean difference against standard error. Identified studies were meta-analyzed and stratified by body mass index, study design, dietary methodology, and country status (developed/developing) by the use of a random-effects model., Results: Of 2487 articles screened, 18 studies met inclusion criteria. On average, women gained 12.0 (2.8) kg (standardized mean difference = 1.306, P < .0005) yet reported only a small increment in energy intake that did not reach statistical significance (∼475 kJ/day, standard mean difference = 0.266, P = .016). Irrespective of baseline body mass index, study design, dietary methodology, or country status, changes in energy intake were not significantly correlated to the amount of gestational weight gain (r = 0.321, P = .11)., Conclusion: Despite rapid physiologic weight gain, women report little or no change in energy intake during pregnancy. Current recommendations to increase energy intake by ∼ 1000 kJ/day may, therefore, encourage excessive weight gain and adverse pregnancy outcomes., (Copyright © 2016 Elsevier Inc.
