'Food can help numb the pain': A mixed methods exploration of disordered eating, shame and self-compassion in an international community sample of men and women.

Background: Research into disordered eating (DE), shame and self-compassion (SC) has poorly represented men, general populations and non-Western communities. Aim: To explore associations between these variables in an international community sample of men and women. Methods: An online exploratory sequential mixed methods cross-sectional survey assessed levels of (quantitative Phase 1) and perceptions of (qualitative Phase 2) eating behaviours, external shame and body image shame (BIS) and SC. Results: Phase 1: Nearly 60% of our 142 survey participants were male (82/142) and about one-third were from India (43/142). About one-third of people (41/142) had a high-level concern regarding dieting, body weight, or eating (based on Eating Attitudes Test scores), and they had significantly higher levels of external shame, BIS and (SC-related) self-judgement and overidentification - compared to the 101/142 participants with low concern. Men had healthier levels of study outcomes than women. Phase 2: Four key themes were identified using inductive thematic analysis of the responses of 55 survey participants: (T1) DE as a Psychological Issue, (T2) DE as a Social Issue, (T3) The Vicious Cycle of Shame and (T4) Seeking Help. Conclusion: In participants in Phase 1 of our study - who were mostly male - DE behaviours were related to more external shame and body image-specific shame, and to less SC. Men had healthier levels of study variables than women. In Phase 2, participants talked about a vicious cycle of pathological eating and shame.

A consensus document on definition and diagnostic criteria for orthorexia nervosa.

PURPOSE: Since the term orthorexia nervosa (ON) was coined from the Greek (ὀρθός, right and ὄρεξις, appetite) in 1997 to describe an obsession with "correct" eating, it has been used worldwide without a consistent definition. Although multiple authors have proposed diagnostic criteria, and many theoretical papers have been published, no consensus definition of ON exists, empirical primary evidence is limited, and ON is not a standardized diagnosis. These gaps prevent research to identify risk and protective factors, pathophysiology, functional consequences, and evidence-based therapeutic treatments. The aims of the current study are to categorize the common observations and presentations of ON pathology among experts in the eating disorder field, propose tentative diagnostic criteria, and consider which DSM chapter and category would be most appropriate for ON should it be included. METHODS: 47 eating disorder researchers and multidisciplinary treatment specialists from 14 different countries across four continents completed a three-phase modified Delphi process, with 75% agreement determined as the threshold for a statement to be included in the final consensus document. In phase I, participants were asked via online survey to agree or disagree with 67 statements about ON in four categories: A-Definition, Clinical Aspects, Duration; B-Consequences; C-Onset; D-Exclusion Criteria, and comment on their rationale. Responses were used to modify the statements which were then provided to the same participants for phase II, a second round of feedback, again in online survey form. Responses to phase II were used to modify and improve the statements for phase III, in which statements that met the predetermined 75% of agreement threshold were provided for review and commentary by all participants. RESULTS: 27 statements met or exceeded the consensus threshold and were compiled into proposed diagnostic criteria for ON. CONCLUSIONS: This is the first time a standardized definition of ON has been developed from a worldwide, multidisciplinary cohort of experts. It represents a summary of observations, clinical expertise, and research findings from a wide base of knowledge. It may be used as a base for diagnosis, treatment protocols, and further research to answer the open questions that remain, particularly the functional consequences of ON and how it might be prevented or identified and intervened upon in its early stages. Although the participants encompass many countries and disciplines, further research will be needed to determine if these diagnostic criteria are applicable to the experience of ON in geographic areas not represented in the current expert panel. LEVEL OF EVIDENCE: Level V: opinions of expert committees.

Comparison of free-living physical activity data obtained from a Fitbit Zip, the Apple iPhone Health app and a modified Bouchard Activity Record.

ISSUE ADDRESSED: Physical activity tracking devices have potential to improve public health, but their data needs to be reliable. No study has compared movement data between the Fitbit Zip, Apple iPhone Health app and physical activity records in a community setting over 10 days. METHODS: University students aged 18+ years wore both a Fitbit Zip and an iPhone at/near their right waist and completed a modified Bouchard Activity Record (BAR) for 10 days in a free-living setting. Comparisons were made between the Fitbit Zip and iPhone for the number of steps and the distance travelled and between the Fitbit Zip and BAR for the minutes of activity in three different intensities. RESULTS: Eighteen students provided sufficient data for inclusion. There were strong correlations between steps per day (r = .87) and distance travelled (r = .88) between the Fitbit Zips and iPhones. However, the Fitbit Zip measured significantly more steps per day (mean 8437 vs 7303; P ≤ .001) and greater distances (mean 5.9 vs 4.9; P ≤ .001) than the iPhone. Correlations between the Fitbit Zips and the BARs were moderate for minutes of total (r = .51) and light (r = .40) activity and weak for moderate/fairly active (r = .20) and vigorous/very active (r = .25). CONCLUSIONS: There were strong correlations between the physical activity data measured by Fitbit Zips and iPhones, but the iPhone Health app significantly underestimated the number of steps per day taken and the distance travelled when compared to the Fitbit Zip. SO WHAT?: Understanding the comparability of accelerometer devices provides useful information for future pragmatic physical activity measurement.

Community-based efforts to prevent obesity: Australia-wide survey of projects.

ISSUES ADDRESSED: Community-based programs that affect healthy environments and policies have emerged as an effective response to high obesity levels in populations. Apart from limited individual reports, little is currently known about these programs, limiting the potential to provide effective support, to promote effective practice, prevent adverse outcomes and disseminate intervention results and experience. The aim of the present study was to identify the size and reach of current community-based obesity prevention projects in Australia and to examine their characteristics, program features (e.g. intervention setting), capacity and approach to obesity prevention. METHODS: Detailed survey completed by representatives from community-based obesity prevention initiatives in Australia. RESULTS: There was wide variation in funding, capacity and approach to obesity prevention among the 78 participating projects. Median annual funding was Au$94900 (range Au$2500-$4.46 million). The most common intervention settings were schools (39%). Forty per cent of programs focused on a population group of ≥50000 people. A large proportion of respondents felt that they did not have sufficient resources or staff training to achieve project objectives. CONCLUSION: Community-based projects currently represent a very large investment by both government and non-government sectors for the prevention of obesity. Existing projects are diverse in size and scope, and reach large segments of the population. Further work is needed to identify the full extent of existing community actions and to monitor their reach and future 'scale up' to ensure that future activities aim for effective integration into systems, policies and environments. SO WHAT? Community-based programs make a substantial contribution to the prevention of obesity and promotion of healthy lifestyles in Australia. A risk of the current intervention landscape is that effective approaches may go unrecognised due to lack of effective evaluations or limitations in program design, duration or size. Policy makers and researchers must recognise the potential contribution of these initiatives, to both public health and knowledge generation, and provide support for strong evaluation and sustainable intervention designs.

Defining community capacity building: is it possible?

OBJECTIVE: Community capacity building has emerged as an important element in effective health promotion practice. The literature highlights many interpretations of community capacity building. Like other broad concepts such as community and social capital, the term 'community capacity building' is not easily captured. The context in which capacity is built is important and possibly contributes to the array of definitions. METHOD: This paper reviews the definitions of community capacity building in health promotion beginning with early definitions in the 1990s to the latest offered by the WHO's Health Promotion Glossary in 2006. RESULTS: The definitions have a common formula with three features: (1) community capacity building is a process/an approach; (2) capacity building is a collection of domains often referred to as characteristics, aspects, capabilities or dimensions; and (3) definitions incorporate an outcome or the rationale for building capacity. CONCLUSION: The commonality in definition challenges the idea that the term 'capacity building' is fraught with a plethora of meanings. The formula can be utilised by communities needing to define capacity building for their own purposes, in their own contexts.

Effect of the glycemic index of carbohydrates on Acne vulgaris.

Acne vulgaris may be improved by dietary factors that increase insulin sensitivity. We hypothesized that a low-glycemic index diet would improve facial acne severity and insulin sensitivity. Fifty-eight adolescent males (mean age ± standard deviation 16.5 ± 1.0 y and body mass index 23.1 ± 3.5 kg/m(2)) were alternately allocated to high or low glycemic index diets. Severity of inflammatory lesions on the face, insulin sensitivity (homeostasis modeling assessment of insulin resistance), androgens and insulin-like growth factor-1 and its binding proteins were assessed at baseline and at eight weeks, a period corresponding to the school term. Forty-three subjects (n = 23 low glycemic index and n = 20 high glycemic index) completed the study. Diets differed significantly in glycemic index (mean ± standard error of the mean, low glycemic index 51 ± 1 vs. high glycemic index 61 ± 2, p = 0.0002), but not in macronutrient distribution or fiber content. Facial acne improved on both diets (low glycemic index -26 ± 6%, p = 0.0004 and high glycemic index -16 ± 7%, p = 0.01), but differences between diets did not reach significance. Change in insulin sensitivity was not different between diets (low glycemic index 0.2 ± 0.1 and high glycemic index 0.1 ± 0.1, p = 0.60) and did not correlate with change in acne severity (Pearson correlation r = -0.196, p = 0.244). Longer time frames, greater reductions in glycemic load or/and weight loss may be necessary to detect improvements in acne among adolescent boys.
