© 2018 Public Health Association of Australia. Objective: To describe the prevalence and change in prevalence of electronic nicotine delivery systems (ENDS) use in youth by country and combustible smoking status. Methods: Databases and the grey literature were systematically searched to December 2015. Studies describing the prevalence of ENDS use in the general population aged =20 years in a defined geographical region were included. Where multiple estimates were available within countries, prevalence estimates of ENDS use were pooled for each country separately. Results: Data from 27 publications (36 surveys) from 13 countries were included. The prevalence of ENDS ever use in 2013-2015 among youth were highest in Poland (62.1%; 95%CI: 59.9-64.2%), and lowest in Italy (5.9%; 95%CI: 3.3-9.2%). Among non-smoking youth, the prevalence of ENDS ever use in 2013-2015 varied, ranging from 4.2% (95%CI: 3.8-4.6%) in the US to 14.0% in New Zealand (95%CI: 12.7-15.4%). The prevalence of ENDS ever use among current tobacco smoking youth was the highest in Canada (71.9%, 95%CI: 70.9-72.8%) and lowest in Italy (29.9%, 95%CI: 18.5-42.5%). Between 2008 and 2015, ENDS ever use among youth increased in Poland, Korea, New Zealand and the US; decreased in Italy and Canada; and remained stable in the UK. Conclusions: There is considerable heterogeneity in ENDS use among youth globally across countries and also between current smokers and non-smokers. Implications for public health: Population-level survey data on ENDS use is needed to inform public health policy and messaging globally.

© 2016 The Authors The aim of this study was to describe the research output and citation rates (academic impact) of public health dissemination and implementation research according to research design and study type. A cross sectional bibliographic study was undertaken in 2013. All original data-based studies and review articles focusing on dissemination and implementation research that had been published in 10 randomly selected public health journals in 2008 were audited. The electronic database ¿Scopus¿ was used to calculate 5-year citation rates for all included publications. Of the 1648 publications examined, 216 were original data-based research or literature reviews focusing on dissemination and implementation research. Of these 72% were classified as descriptive/epidemiological, 26% were intervention and just 1.9% were measurement research. Cross-sectional studies were the most common study design (47%). Reviews, randomized trials, non-randomized trials and decision/cost-effectiveness studies each represented between 6 and 10% of all output. Systematic reviews, randomized controlled trials and cohort studies were the most frequently cited study designs. The study suggests that publications that had the greatest academic impact (highest citation rates) made up only a small proportion of overall public health dissemination and implementation research output.

© 2016 The Obesity Society. Objective This review aimed to examine the impact of interventions involving an explicit sleep component on child body mass index (BMI), diet, and physical activity. Methods A systematic search was undertaken in six databases to identify randomized controlled trials examining the impact of interventions with a sleep component on child BMI, dietary intake, and/or physical activity. A random effects meta-analysis was conducted assessing the impact of included interventions on child BMI. Results Of the eight included trials, three enforced a sleep protocol and five targeted sleep as part of multicomponent behavioral interventions either exclusively or together with nutrition and physical activity. Meta-analysis of three studies found that multicomponent behavioral interventions involving a sleep component were not significantly effective in changing child BMI (n = 360,-0.04 kg/m 2 [-0.18, 0.11], I 2 = 0%); however, only one study included in the meta-analysis successfully changed sleep duration in children. There were some reported improvements to adolescent diet, and only one trial examined the impact on child physical activity, where a significant effect was observed. Conclusions Findings from the included studies suggest that where improvements in child sleep duration were achieved, a positive impact on child BMI, nutrition, and physical activity was also observed.

© 2015 Dietitians Association of Australia Aim: To compare dietary intakes of young children to the Australian Guide to Healthy Eating (AGHE) and Nutrient Reference Values (NRVs). Methods: Dietary intakes of 54 children (50% girls) aged two to three years (mean 2.7 years) from the Women and Their Children's Health (WATCH) study were reported by mothers using a validated 120-item food frequency questionnaire. Daily consumption of AGHE food group servings, macronutrients, and micronutrients were compared to the AGHE and NRVs using t-test with significance set at P < 0.05. Results: No child achieved all AGHE targets, with the majority consuming less breads/cereals (1.9 vs 4.0 servings/day), vegetables (1.3 vs 2.5), and meat/alternatives (0.7 vs 1.0), all P < 0.0001. Adequate servings were observed for dairy (2.2 vs 1.5) and fruit (1.3 vs 1.0). Macronutrients were within recommended ranges, although 96% exceeded saturated fatty acid recommendations. Children who met selected NRVs consumed more fruit (1.4 vs 1.0; P < 0.0086), dairy (2.2 vs 1.5; P < 0.0001) and discretionary foods (2.6 vs =1.0; P < 0.0001) but less breads/cereals (2.0 vs 4.0; P < 0.0001) and vegetables (1.3 vs 2.5; P < 0.0001) servings, compared to the AGHE recommended servings. Conclusions: Child dietary intakes did not align with AGHE, while adequate nutrient profiles were achieved by various dietary patterns. Future studies involving data from larger, representative samples of children are warranted.

� 2016 Joanna Briggs Institute. Review question/objective: The main objective of this umbrella review is to identify the effectiveness of family- based interventions that target overweight or obesity in children aged 18 years and under. The umbrella review intends to compare and summarize existing systematic reviews of experimental studies that address a range of family-based interventions for overweight children. Family-based is defined as the involvement of first- or second- degree relatives or carers who are cohabiting under one roof. 1 The second objective of this umbrella review is to identify strategies that are effective in improving children¿s body weight or body mass index (primary outcomes) and, where applicable, changes in child/family behavior, including dietary intake or physical activity. The review questions are as follows: What is the effectiveness of family-based behavioral or lifestyle weight management interventions for overweight children? What are the strategies or characteristics of effective interventions in combating child obesity?

© 2015 by the authors; licensee MDPI, Basel, Switzerland. With the growth of Internet technologies, offering interventions for child and family weight management in an online format may address barriers to accessing services. This study aimed to investigate (i) whether an eHealth family healthy lifestyle program would be of interest to parents; and (ii) preferences and/or expectations for program components and features. Parents of children aged four to18 years were recruited through social media and completed an online survey (54 items) including closed and open-ended questions. Responses were collated us ing descriptive statistics and thematic analysis. Seventy-five participants were included (92% mothers, mean age 39.1 ± 8.6 years, mean BMI 27.6 ± 6.3 kg/m 2 ). The index child had a mean age of 11 ± 6.2 years with 24% overweight/obese. The majority of parents (90.3%) reported interest in an online program, with preference expressed for a non-structured program to allow flexibility users to log-on and off as desired. Parents wanted a program that was easy to use, practical, engaging, endorsed by a reputable source, and able to provide individual tailoring and for their children to be directly involved. The current study supports the need for online delivery of a healthy lifestyle program that targets greater parental concerns of diet rather than child weight.
