This is gaining prominence as an alternative weight-loss strategy to daily energy restriction (DER). The aim of this systematic review was to determine the effectiveness of IER on weight loss in overweight and obese adults and compare this with DER. SUBJECTS/METHODS: A systematic literature search was conducted using the CINAHL, Embase, Medline, PsycINFO, Cochrane and Scopus databases. Eight studies that assigned overweight or obese adults to IER or to a DER 'control' were deemed eligible for inclusion. RESULTS: All studies reported significant weight loss for IER groups. Average weight loss was approximately 0.2-0.8 kg per week. IER resulted in comparable weight loss to DER when overall energy restriction remained similar between diets. The majority of studies that reported body composition outcomes have shown equal efficacy for fat mass, fat-free mass and waist circumference. CONCLUSIONS: Weight loss was achieved in overweight and obese adults following IER and this loss was comparable to a DER diet. IER may be an effective alternative strategy for health practitioners to promote weight loss for selected overweight and obese people.

A link to the journal article is found below (Rounsefell et al, 2019, DOI 10.1111/1747-0080.12581). Abstract Aim Negative body image increases the risk of engaging in unhealthy dieting and disordered eating patterns. This review evaluated the impact of habitual social media engagement or exposure to image-related content on body image and food choices in healthy young adults (18-30 years). Methods A systematic search of six databases of observational literature published 2005-2019, was conducted (PROSPERO Registration No. CRD42016036588). Inclusion criteria were: studies reporting social media engagement (posting, liking, commenting) or exposure to image-related content in healthy young adults. Outcomes were: body image (satisfaction or dissatisfaction) and food choices (healthy eating, dieting/restricting, overeating/binging). Two authors independently screened, coded and evaluated studies for methodological quality. Results Thirty studies were identified (n = 11125 participants). Quantitative analysis (n = 26) identified social media engagement or exposure to image-related content was associated with higher body dissatisfaction, dieting/restricting food, overeating, and choosing healthy foods. Qualitative analysis (n = 4) identified five themes: (i) social media encourages comparison between users, (ii) comparisons heighten feelings about the body, (iii) young adults modify their appearance to portray a perceived ideal image, (iv) young adults are aware of social media's impact on body image and food choices, however, (v) external validation via social media is pursued. Most studies (n = 17) controlled for some confounding variables (age, gender, BMI, ethnicity). Conclusions Social media engagement or exposure to image-related content may negatively impact body image and food choice in some [...]

A sequential explanatory mixed-methods study design utilised a survey to quantify commitment to Aboriginal health policy followed by in-depth interviews that explored how and why policy or programs were in place. Data were analysed separately and then interpreted together. Representatives from 39 of Victoria’s 79 local governments (49%) responded to the survey and 14 were interviewed. Seventy-four per cent had policy and programs addressing Aboriginal health and wellbeing. The key factors influencing policy and program development were: (i) the process of policy and program development and implementation and the role of other policies; (ii) the influence of Aboriginal community characteristics; and (iii) advocacy for Aboriginal health and wellbeing. Underpinning ...

In the state of Victoria, Australia, all seventy-nine local governments' public health policy documents were retrieved. Inclusion of Aboriginal health and nutrition in policy documents was analysed using quantitative content analysis. Representation of Aboriginal nutrition 'problems' and 'solutions' was examined using qualitative framing analysis. The socio-ecological framework was used to classify the types of Aboriginal nutrition issues and strategies within policy documents. Victoria, Australia. Local governments' public health policy documents (n 79). A small proportion (14 %, n 11) of local governments addressed Aboriginal health and well-being in terms of nutrition. Where strategies aimed at nutrition existed, they mostly focused on individual ...
