Abstract
BACKGROUND Afterschool interventions have been found to improve the nutritional quality of snacks served. However, there is limited evidence on how these interventions affect children's snacking behaviors. OBJECTIVE Our aim was to determine the impact of an afterschool intervention focused at the school district, site, family, and child levels on dietary consumption of foods and beverages served at snack. DESIGN This was a secondary analysis of a group-randomized controlled trial. PARTICIPANTS/SETTING Data were collected from 400 children at 20 afterschool sites in Boston, MA before (fall 2010) and after (spring 2011) intervention implementation. INTERVENTION The Out-of-School Nutrition and Physical Activity intervention aimed to promote fruits, vegetables, whole grains, and water, while limiting sugary drinks and trans fats. Researchers worked with district foodservice staff to change snack foods and beverages. Teams of afterschool staff participated in three 3-hour learning collaborative sessions to build skills and created action plans for changing site practices. The intervention included family and child nutrition education. MAIN OUTCOME MEASURES Research assistants observed dietary snack consumption using a validated measure on 2 days per site at baseline and follow-up. STATISTICAL ANALYSES PERFORMED This study used multivariable regression models, accounting for clustering of observations, to assess the intervention effect, and conducted post-hoc stratified analyses by foodservice type. RESULTS Children in intervention sites had greater decreases in consumption of juice (-0.61 oz/snack, 95% CI -1.11 to -0.12), beverage calories (-29.1 kcal/snack, 95% CI -40.2 to 18.0), foods with trans fats (-0.12 servings/snack, 95% CI -0.19 to -0.04), total calories (-47.7 kcal/snack, 95% CI -68.2 to -27.2), and increases in consumption of whole grains (0.10 servings/snack, 95% CI 0.02 to 0.18) compared to controls. In post-hoc analyses, sites with on-site foodservice had significant improvements for all outcomes (P<0.001), with no effect for sites with satellite foodservice. CONCLUSIONS Results demonstrate that an afterschool intervention can improve children's dietary snack consumption, particularly at sites with on-site foodservice.

Abstract
In the United States, 32% of beverages consumed by adults and 19% of beverages consumed by children in 2007 to 2010 contained low-calorie sweeteners (LCSs). Among all foods and beverages containing LCSs, beverages represent the largest proportion of LCS consumption worldwide. The term LCS includes the 6 high-intensity sweeteners currently approved by the US Food and Drug Administration and 2 additional high-intensity sweeteners for which the US Food and Drug Administration has issued no objection letters. Because of a lack of data on specific LCSs, this advisory does not distinguish among these LCSs. Furthermore, the advisory does not address foods sweetened with LCSs. This advisory reviews evidence from observational studies and clinical trials assessing the cardiometabolic outcomes of LCS beverages. It summarizes the positions of government agencies and other health organizations on LCS beverages and identifies research needs on the effects of LCS beverages on energy balance and cardiometabolic health. The use of LCS beverages may be an effective strategy to help control energy intake and promote weight loss. Nonetheless, there is a dearth of evidence on the potential adverse effects of LCS beverages relative to potential benefits. On the basis of the available evidence, the writing group concluded that, at this time, it is prudent to advise against prolonged consumption of LCS beverages by children. (Although water is the optimal beverage choice, children with diabetes mellitus who consume a balanced diet and closely monitor their blood glucose may be able to prevent excessive glucose excursions by substituting LCS beverages for sugar-sweetened beverages [SSBs] when needed.) For adults who are habitually high consumers of SSBs, the writing group concluded that LCS beverages may be a useful replacement strategy to reduce intake of SSBs. This approach may be particularly helpful for persons who are habituated to a sweet-tasting beverage and for whom water, at least initially, is an undesirable option. Encouragingly, self-reported consumption of both SSBs and LCS beverages has been declining in the United States, suggesting that it is feasible to reduce SSB intake without necessarily substituting LCS beverages for SSBs. Thus, the use of other alternatives to SSBs, with a focus on water (plain, carbonated, and unsweetened flavored), should be encouraged.

Abstract
The 2015 Dietary Guidelines for Americans Advisory Committee has set recommendations to limit added sugars. This action was based on the association between dietary pattern quality scores and chronic disease risk, the results of meta-analyses conducted for the World Health Organization, and data from modeling of dietary patterns for establishing the US Department of Agriculture's Healthy US-Style Eating Patterns. Recommendations provided by the 2015-2020 Dietary Guidelines for Americans were used by the US Food and Drug Administration to establish, for the first time, the mandatory declaration of added sugars and a Daily Value of added sugars for the Nutrition Facts label. This review provides an overview of the scientific evidence considered by the World Health Organization, the 2015-2020 Dietary Guidelines for Americans, and the US Food and Drug Administration for setting recent polices and regulations on added sugars and highlights important issues and inconsistencies in the evaluations and interpretations of the evidence.

Abstract
Consumption of sugar-sweetened beverages (SSBs) increases total caloric intake, is linked to cardiometabolic outcomes as well as dental caries, and sugar in SSBs is associated with mortality and frailty among adults. We describe energy and total sugar intake trends among the United States (US) population from SSBs, soft drinks, other beverage groups, and the total diet based on the first 24-h recall data from the National Health and Nutrition Examination Survey (NHANES) cycles (2003-2004 through 2015-2016). SSBs included soft drinks, sports drinks, energy drinks, and fruit drinks, but excluded sports beverages with protein and sweetened teas/coffees. Among the total population (age ≥2 years: 57,026), energy intake from SSBs declined significantly from 183.9 ± 6.9 mean kcal/d (±SE) in 2003-2004 to 95.0 ± 3.5 in 2015-2016, while total sugar intake declined from 43.6 ± 1.7 mean g/d to 22.3 ± 0.8 (p-trend < 0.0001). Decreases were found for energy and total sugar intake, as well as percentage of energy and total sugar intake from SSBs, soft drinks, and all beverages for all age groups examined (≥2, 2-19, ≥20 years) (p-trend < 0.0001). From 2003 to 2016, energy and sugar intake from all beverages, SSBs, soft drinks, and the total diet decreased among the total population, children, and adults.

Abstract
Sugar-sweetened beverages (SSBs) have little nutritional value and a robust body of evidence has linked the intake of SSBs to weight gain and risk of type 2 diabetes (T2D), cardiovascular disease (CVD), and some cancers. Metabolic Syndrome (MetSyn) is a clustering of risk factors that precedes the development of T2D and CVD; however, evidence linking SSBs to MetSyn is not clear. To make informed recommendations about SSBs, new evidence needs to be considered against existing literature. This review provides an update on the evidence linking SSBs and cardiometabolic outcomes including MetSyn. Findings from prospective cohort studies support a strong positive association between SSBs and weight gain and risk of T2D and coronary heart disease (CHD), independent of adiposity. Associations with MetSyn are less consistent, and there appears to be a sex difference with stroke with greater risk in women. Findings from short-term trials on metabolic risk factors provide mechanistic support for associations with T2D and CHD. Conclusive evidence from cohort studies and trials on risk factors support an etiologic role of SSB in relation to weight gain and risk of T2D and CHD. Continued efforts to reduce intake of SSB should be encouraged to improve the cardiometabolic health of individuals and populations.

Abstract
PURPOSE OF REVIEW Various policies to reduce sugar-sweetened beverages (SSBs) consumption in children have been implemented. Here, we review the evidence on whether these policies are effective in reducing SSB intake and whether a reduction in SSB intake results in a concomitant reduction in child obesity. We also highlight ethical concerns with such efforts. RECENT FINDINGS The evidence supporting relationship between SSB consumption and child body mass index (BMI) is consistently small and lacks causality. The effects of policies are unclear; taxation has no clear relationship to SSB purchasing, innovative marketing outlets make it difficult to examine the effects of restricting marketing on SSB consumption, and there is no evidence that reducing SSB availability in schools decreases consumption. Research studies with rigorous and reproducible study designs are needed to examine whether reducing SSB consumption reduces child obesity, and to identify implementable policies that not only reduce SSB consumption but also child weight.

Abstract
A reduction in the consumption of added sugars and sugar-sweetened beverages (SSBs) is a key focus of public health recommendations for a healthy diet among children. One approach to lower added sugar intake is to instead use low-calorie sweeteners (LCSs), which contain no or few calories. Consumption of LCSs is increasing worldwide, with the most marked rise observed among children and adolescents. However, the extent to which LCS consumption is helpful or harmful for weight management is controversial, particularly when LCS consumption begins in childhood. Herein, we summarize the limited existing literature examining effects of paediatric LCS consumption on appetite, energy intake, and body weight. While positive associations between LCS consumption and weight gain are reported in observational analyses, the majority of intervention studies, some of which blinded children to the contents of the drinks, report benefits of LCSs for reducing excessive child weight gain. Several potential mechanisms have been proposed to explain LCS effects on body weight, including LCS-induced promotion of appetite and energy intake. Yet studies assessing effects of beverages with LCSs (LCSBs) compared with SSBs on child appetite report mixed findings. Some demonstrate that children completely compensate for the diluted energy content of LCSBs by eating more solid food calories at subsequent meals compared with children administered SSBs, while others report a reduction in total energy intake with LCSB ingestion. Given the limited studies and resulting uncertainty as to whether LCSs benefit or worsen weight and metabolic health in children is integral that effects of LCS use during childhood continue to be investigated in future prospective studies.

Abstract
CONTEXT The consumption of high-fructose beverages is associated with a higher risk for obesity and diabetes. Fructose can stimulate glucagon-like peptide 1 (GLP-1) secretion in lean adults, in the absence of any anorexic effect. OBJECTIVE We hypothesized that the ingestion of glucose and fructose may differentially stimulate GLP-1 and insulin response in lean adolescents and adolescents with obesity. DESIGN We studied 14 lean adolescents [four females; 15.9 ± 1.6 years of age; body mass index (BMI), 21.8 ± 2.2 kg/m2] and 23 adolescents with obesity (five females; 15.1 ± 1.6 years of age; BMI, 34.5 ± 4.6 kg/m2). Participants underwent a baseline oral glucose tolerance test to determine their glucose tolerance and estimate insulin sensitivity and β-cell function [oral disposition index (oDIcpep)]. Eligible subjects received, in a double-blind, crossover design, 75 g of glucose or fructose. Plasma was obtained every 10 minutes for 60 minutes for the measures of glucose, insulin, and GLP-1 (radioimmunoassay) and glucose-dependent insulinotropic polypeptide (GIP; ELISA). Incremental glucose and hormone levels were compared between lean individuals and those with obesity by a linear mixed model. The relationship between GLP-1 increment and oDIcpep was evaluated by regression analysis. RESULTS Following the fructose challenge, plasma glucose excursions were similar in both groups, yet the adolescents with obesity exhibited a greater insulin (P < 0.001) and GLP-1 (P < 0.001) increase than did their lean peers. Changes in GIP were similar in both groups. After glucose ingestion, the GLP-1 response (P < 0.001) was higher in the lean group. The GLP-1 increment during 60 minutes from fructose drink was correlated with a lower oDIcpep (r2 = 0.22, P = 0.009). CONCLUSION Fructose, but not glucose, ingestion elicits a higher GLP-1 and insulin response in adolescents with obesity than in lean adolescents. Fructose consumption may contribute to the hyperinsulinemic phenotype of adolescent obesity through a GLP-1-mediated mechanism.

Abstract
Systematic reviews of nutritional interventions indicate limited efficacy in reducing childhood obesity, but their blanket conclusions could obscure promising components. This narrative review sought more detail on effective components within nutrition-related interventions involving children aged 2 to 11 years. In May 2016, the World Health Organization (WHO) searched the Cochrane Library and PubMed for relevant reviews. From 36 reviews, we screened 182 nutrition-related randomized trials for inclusion. We then reviewed those that reported at least 1 statistically significant (P < 0.05) treatment benefit on body weight and/or composition outcomes at their longest follow-up assessment. Fourteen trials met inclusion criteria (median n = 554; mean intervention duration = 10.8 mo; follow-up = 4.4 mo). "Effective" approaches included environmental changes such as school water fountain installations and cafeteria menu changes and possibly less sustainable strategies such as health education lessons. However, effect sizes even of these selected significant treatment benefits were modest-significant body mass index z-score effects range from -0.1 to -0.2. Each trial was associated with very small improvements in body composition. Because this is a "best-case" scenario (reflecting our design), trialists should rigorously test these strategies alone and possibly together; be open to novel strategies; and ensure that each strategy is culturally relevant and self-sustainable.

Abstract
BACKGROUND Efficacious strategies to reduce sugar-sweetened beverage (SSB) consumption among youth are needed. This pilot study assessed the feasibility and preliminary efficacy of a community-based youth empowerment intervention to reduce SSB consumption and obesity risk among a low-income, ethnically diverse sample of youth. METHODS The H2GO! intervention was pilot-tested in an afterschool setting (Boys and Girls Clubs (BGC)) in Massachusetts, USA. One site was randomized to receive the intervention; the other site received standard programming. Youth ages 9-12 years and their parents/caregivers were eligible to participate. A total of N = 110 parent-child pairs (N = 55 parent-child pairs per site) were recruited. The 6-week intervention consisted of group-based weekly sessions delivered by trained BGC staff and youth-led activities that engaged parents. Child outcomes included self-reported SSB and water intake and measured body mass index z scores (zBMI). Parent outcomes included self-reported SSB and water intake, SSB purchasing, and availability of SSBs at home. Outcomes were measured at baseline, 2 months, and 6 months. Generalized linear and logistic regression models were used to estimate intervention effects over time. RESULTS The final analytic study sample consisted of 100 child participants (38% Black, 20% Hispanic, 13% White, 12% Multiracial, 11% Asian) and 87 parent participants (78.2% female; 78.2% reporting eligibility for the free-or-reduced price lunch program). 6-month retention rates were ≥ 82%. Intervention attendance rates among intervention child participants (N = 51) averaged 78.1% (SD = 10.3). Over half (56.0%) of child participants were overweight or obese at baseline. Relative to the comparison site, intervention site child participants had decreased SSB intake (β = - 1.64; 95% CI: 2.52, - 0.76), increased water intake (β = 1.31; 95% CI: 0.38, 2.23), and decreased zBMI (- 0.23 units; 95% CI: - 0.31, - 0.14) over 6 months (p < 0.001). Intervention parent participants also reported decreased SSB intake (β = - 1.76; 95% CI: - 2.56, - 0.96) and increased water intake (β = 1.75; 95% CI: 1.11, 2.40) than comparison parent participants at 6 months (p < 0.001). CONCLUSIONS Findings demonstrate the potential of a youth empowerment intervention on reducing SSB intake and zBMI among a diverse sample. Findings will guide a larger cluster-randomized controlled trial to test intervention efficacy on preventing childhood obesity, as well as inform future interventions that aim to target additional diet and physical activity behaviors through youth empowerment.

Abstract
BACKGROUND Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies to prevent obesity is very large and is accumulating rapidly. This is an update of a previous review. OBJECTIVES To determine the effectiveness of a range of interventions that include diet or physical activity components, or both, designed to prevent obesity in children. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, PsychINFO and CINAHL in June 2015. We re-ran the search from June 2015 to January 2018 and included a search of trial registers. SELECTION CRITERIA Randomised controlled trials (RCTs) of diet or physical activity interventions, or combined diet and physical activity interventions, for preventing overweight or obesity in children (0-17 years) that reported outcomes at a minimum of 12 weeks from baseline. DATA COLLECTION AND ANALYSIS Two authors independently extracted data, assessed risk-of-bias and evaluated overall certainty of the evidence using GRADE. We extracted data on adiposity outcomes, sociodemographic characteristics, adverse events, intervention process and costs. We meta-analysed data as guided by the Cochrane Handbook for Systematic Reviews of Interventions and presented separate meta-analyses by age group for child 0 to 5 years, 6 to 12 years, and 13 to 18 years for zBMI and BMI. MAIN RESULTS We included 153 RCTs, mostly from the USA or Europe. Thirteen studies were based in upper-middle-income countries (UMIC: Brazil, Ecuador, Lebanon, Mexico, Thailand, Turkey, US-Mexico border), and one was based in a lower middle-income country (LMIC: Egypt). The majority (85) targeted children aged 6 to 12 years.Children aged 0-5 years: There is moderate-certainty evidence from 16 RCTs (n = 6261) that diet combined with physical activity interventions, compared with control, reduced BMI (mean difference (MD) -0.07 kg/m2, 95% confidence interval (CI) -0.14 to -0.01), and had a similar effect (11 RCTs, n = 5536) on zBMI (MD -0.11, 95% CI -0.21 to 0.01). Neither diet (moderate-certainty evidence) nor physical activity interventions alone (high-certainty evidence) compared with control reduced BMI (physical activity alone: MD -0.22 kg/m2, 95% CI -0.44 to 0.01) or zBMI (diet alone: MD -0.14, 95% CI -0.32 to 0.04; physical activity alone: MD 0.01, 95% CI -0.10 to 0.13) in children aged 0-5 years.Children aged 6 to 12 years: There is moderate-certainty evidence from 14 RCTs (n = 16,410) that physical activity interventions, compared with control, reduced BMI (MD -0.10 kg/m2, 95% CI -0.14 to -0.05). However, there is moderate-certainty evidence that they had little or no effect on zBMI (MD -0.02, 95% CI -0.06 to 0.02). There is low-certainty evidence from 20 RCTs (n = 24,043) that diet combined with physical activity interventions, compared with control, reduced zBMI (MD -0.05 kg/m2, 95% CI -0.10 to -0.01). There is high-certainty evidence that diet interventions, compared with control, had little impact on zBMI (MD -0.03, 95% CI -0.06 to 0.01) or BMI (-0.02 kg/m2, 95% CI -0.11 to 0.06).Children aged 13 to 18 years: There is very low-certainty evidence that physical activity interventions, compared with control reduced BMI (MD -1.53 kg/m2, 95% CI -2.67 to -0.39; 4 RCTs; n = 720); and low-certainty evidence for a reduction in zBMI (MD -0.2, 95% CI -0.3 to -0.1; 1 RCT; n = 100). There is low-certainty evidence from eight RCTs (n = 16,583) that diet combined with physical activity interventions, compared with control, had no effect on BMI (MD -0.02 kg/m2, 95% CI -0.10 to 0.05); or zBMI (MD 0.01, 95% CI -0.05 to 0.07; 6 RCTs; n = 16,543). Evidence from two RCTs (low-certainty evidence; n = 294) found no effect of diet interventions on BMI.Direct comparisons of interventions: Two RCTs reported data directly comparing diet with either physical activity or diet combined with physical activity interventions for children aged 6 to 12 years and reported no differences.Heterogeneity was apparent in the results from all three age groups, which could not be entirely explained by setting or duration of the interventions. Where reported, interventions did not appear to result in adverse effects (16 RCTs) or increase health inequalities (gender: 30 RCTs; socioeconomic status: 18 RCTs), although relatively few studies examined these factors.Re-running the searches in January 2018 identified 315 records with potential relevance to this review, which will be synthesised in the next update. AUTHORS' CONCLUSIONS Interventions that include diet combined with physical activity interventions can reduce the risk of obesity (zBMI and BMI) in young children aged 0 to 5 years. There is weaker evidence from a single study that dietary interventions may be beneficial.However, interventions that focus only on physical activity do not appear to be effective in children of this age. In contrast, interventions that only focus on physical activity can reduce the risk of obesity (BMI) in children aged 6 to 12 years, and adolescents aged 13 to 18 years. In these age groups, there is no evidence that interventions that only focus on diet are effective, and some evidence that diet combined with physical activity interventions may be effective. Importantly, this updated review also suggests that interventions to prevent childhood obesity do not appear to result in adverse effects or health inequalities.The review will not be updated in its current form. To manage the growth in RCTs of child obesity prevention interventions, in future, this review will be split into three separate reviews based on child age.

Abstract
OBJECTIVE To evaluate whether a multipronged pilot intervention promoting healthier beverage consumption improved at-home beverage consumption and weight status among young children. DESIGN In this exploratory pilot study, we randomly assigned four childcare centres to a control (delayed-intervention) condition or a 12-week intervention that promoted consumption of healthier beverages (water, unsweetened low- or non-fat milk) and discouraged consumption of less-healthy beverages (juice, sugar-sweetened beverages, high-fat or sweetened milk). The multipronged intervention was delivered via childcare centres; simultaneously targeted children, parents and childcare staff; and included environmental changes, policies and education. Outcomes were measured at baseline and immediately post-intervention and included children's (n 154) at-home beverage consumption (assessed via parental report) and overweight/obese status (assessed via objectively measured height and weight). We estimated intervention impact using difference-in-differences models controlling for children's demographics and classroom. SETTING Two northern California cities, USA, 2013-2014. PARTICIPANTS Children aged 2-5 years and their parents. RESULTS Relative to control group children, intervention group children reduced their consumption of less-healthy beverages from baseline to follow-up by 5·9 ounces/d (95 % CI -11·2, -0·6) (-174·5 ml/d; 95 % CI -331·2, -17·7) and increased their consumption of healthier beverages by 3·5 ounces/d (95 % CI -2·6, 9·5) (103·5 ml/d; 95 % CI -76·9, 280·9). Children's likelihood of being overweight decreased by 3 percentage points (pp) in the intervention group and increased by 3 pp in the control group (difference-in-differences: -6 pp; 95 % CI -15, 3). CONCLUSIONS Our exploratory pilot study suggests that interventions focused comprehensively on encouraging healthier beverage consumption could improve children's beverage intake and weight. Findings should be confirmed in longer, larger studies.

Abstract
Background: Food insecurity may trigger eating behaviors that contribute to pediatric obesity. The aim of this study is to identify eating behaviors among a pediatric population with obesity and household food insecurity. Methods: A cross-sectional study analyzed Child Eating Behavior Questionnaire (CEBQ) and household food insecurity screener responses, and BMI measurements from pediatric participants with obesity (BMI ≥95th percentile) from a weight management clinic between 2013 and 2017. Multivariate linear regression was performed to evaluate associations between CEBQ eating domains [Food Responsiveness, Emotional Overeating, Enjoyment of Food, Desire to Drink (DD), Satiety Responsiveness, Slowness in Eating, Emotional Undereating (EUE), and Food Fussiness] and household food insecurity, adjusting for age, sex, race/ethnicity, SNAP participation, and BMI percentile. A sub-group analysis was performed on participants from food insecure (FI) households to evaluate the associations between SNAP participation and eating domains. Results: Eight hundred twenty-two participants were included in the final analysis. Participants from FI households had significantly higher BMI percentiles even after adjustment for age, sex, race/ethnicity, and SNAP status (p = 0.000). Household food insecurity was associated with increased DD beverages (p = 0.000). Among participants from FI households, SNAP participation was significantly positively associated with the EUE (p = 0.009). Conclusions: Youth from FI households have higher BMIs even among a population with obesity. DD is positively associated with household food insecurity and may contribute to obesity in this population. Results suggest that providers treating pediatric patients with obesity should consider regularly screening for household food insecurity and associated eating behaviors as part of their medical management of obesity.

Environmental interventions to reduce the consumption of sugar-sweetened beverages and their effects on health. Cochrane Database Syst Rev 2019; 6:CD012292.

Abstract
BACKGROUND Frequent consumption of excess amounts of sugar-sweetened beverages (SSB) is a risk factor for obesity, type 2 diabetes, cardiovascular disease and dental caries. Environmental interventions, i.e. interventions that alter the physical or social environment in which individuals make beverage choices, have been advocated as a means to reduce the consumption of SSB. OBJECTIVES To assess the effects of environmental interventions (excluding taxation) on the consumption of sugar-sweetened beverages and sugar-sweetened milk, diet-related anthropometric measures and health outcomes, and on any reported unintended consequences or adverse outcomes. SEARCH METHODS We searched 11 general, specialist and regional databases from inception to 24 January 2018. We also searched trial registers, reference lists and citations, scanned websites of relevant organisations, and contacted study authors. SELECTION CRITERIA We included studies on interventions implemented at an environmental level, reporting effects on direct or indirect measures of SSB intake, diet-related anthropometric measures and health outcomes, or any reported adverse outcome. We included randomised controlled trials (RCTs), non-randomised controlled trials (NRCTs), controlled before-after (CBA) and interrupted-time-series (ITS) studies, implemented in real-world settings with a combined length of intervention and follow-up of at least 12 weeks and at least 20 individuals in each of the intervention and control groups. We excluded studies in which participants were administered SSB as part of clinical trials, and multicomponent interventions which did not report SSB-specific outcome data. We excluded studies on the taxation of SSB, as these are the subject of a separate Cochrane Review. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies for inclusion, extracted data and assessed the risks of bias of included studies. We classified interventions according to the NOURISHING framework, and synthesised results narratively and conducted meta-analyses for two outcomes relating to two intervention types. We assessed our confidence in the certainty of effect estimates with the GRADE framework as very low, low, moderate or high, and presented 'Summary of findings' tables. MAIN RESULTS We identified 14,488 unique records, and assessed 1030 in full text for eligibility. We found 58 studies meeting our inclusion criteria, including 22 RCTs, 3 NRCTs, 14 CBA studies, and 19 ITS studies, with a total of 1,180,096 participants. The median length of follow-up was 10 months. The studies included children, teenagers and adults, and were implemented in a variety of settings, including schools, retailing and food service establishments. We judged most studies to be at high or unclear risk of bias in at least one domain, and most studies used non-randomised designs. The studies examine a broad range of interventions, and we present results for these separately.Labelling interventions (8 studies): We found moderate-certainty evidence that traffic-light labelling is associated with decreasing sales of SSBs, and low-certainty evidence that nutritional rating score labelling is associated with decreasing sales of SSBs. For menu-board calorie labelling reported effects on SSB sales varied.Nutrition standards in public institutions (16 studies): We found low-certainty evidence that reduced availability of SSBs in schools is associated with decreased SSB consumption. We found very low-certainty evidence that improved availability of drinking water in schools and school fruit programmes are associated with decreased SSB consumption. Reported associations between improved availability of drinking water in schools and student body weight varied.Economic tools (7 studies): We found moderate-certainty evidence that price increases on SSBs are associated with decreasing SSB sales. For price discounts on low-calorie beverages reported effects on SSB sales varied.Whole food supply interventions (3 studies): Reported associations between voluntary industry initiatives to improve the whole food supply and SSB sales varied.Retail and food service interventions (7 studies): We found low-certainty evidence that healthier default beverages in children's menus in chain restaurants are associated with decreasing SSB sales, and moderate-certainty evidence that in-store promotion of healthier beverages in supermarkets is associated with decreasing SSB sales. We found very low-certainty evidence that urban planning restrictions on new fast-food restaurants and restrictions on the number of stores selling SSBs in remote communities are associated with decreasing SSB sales. Reported associations between promotion of healthier beverages in vending machines and SSB intake or sales varied.Intersectoral approaches (8 studies): We found moderate-certainty evidence that government food benefit programmes with restrictions on purchasing SSBs are associated with decreased SSB intake. For unrestricted food benefit programmes reported effects varied. We found moderate-certainty evidence that multicomponent community campaigns focused on SSBs are associated with decreasing SSB sales. Reported associations between trade and investment liberalisation and SSB sales varied.Home-based interventions (7 studies): We found moderate-certainty evidence that improved availability of low-calorie beverages in the home environment is associated with decreased SSB intake, and high-certainty evidence that it is associated with decreased body weight among adolescents with overweight or obesity and a high baseline consumption of SSBs.Adverse outcomes reported by studies, which may occur in some circumstances, included negative effects on revenue, compensatory SSB consumption outside school when the availability of SSBs in schools is reduced, reduced milk intake, stakeholder discontent, and increased total energy content of grocery purchases with price discounts on low-calorie beverages, among others. The certainty of evidence on adverse outcomes was low to very low for most outcomes.We analysed interventions targeting sugar-sweetened milk separately, and found low- to moderate-certainty evidence that emoticon labelling and small prizes for the selection of healthier beverages in elementary school cafeterias are associated with decreased consumption of sugar-sweetened milk. We found low-certainty evidence that improved placement of plain milk in school cafeterias is not associated with decreasing sugar-sweetened milk consumption. AUTHORS' CONCLUSIONS The evidence included in this review indicates that effective, scalable interventions addressing SSB consumption at a population level exist. Implementation should be accompanied by high-quality evaluations using appropriate study designs, with a particular focus on the long-term effects of approaches suitable for large-scale implementation.

[PMID: 30987919 PMCID: PMC6536342 DOI: 10.1016/j.jand.2019.02.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Revised: 01/24/2019] [Accepted: 02/11/2019] [Indexed: 11/17/2022]
Abstract
BACKGROUND Alaska Native children, including children of Yup'ik descent, consume large volumes of sugar-sweetened fruit drinks, which contain added sugars that contribute to obesity, diabetes, and dental caries. To date, taste preference evaluations have not been conducted on commercially available sugar-free fruit drinks. OBJECTIVE The study tested the hypothesis that children would have equal preference for sugar-free and sugar-sweetened fruit drinks. DESIGN This was an experimental two-alternative forced-choice paired preference test. PARTICIPANTS/SETTING The study focused on a convenience sample of Yup'ik children, aged 7 to 10 years, recruited and enrolled from the Yukon-Kuskokwim Health Corporation dental clinic in Bethel, AK (N=89). INTERVENTION Children evaluated four different commercially available sugar-free fruit drinks paired with the sugar-sweetened versions of each flavor. Order of flavor pair presentation was alternated across children, and order of presentation within each of the four pairs was randomized across pairs. MAIN OUTCOME MEASURES The outcome was taste preference for the sugar-free versus the sugar-sweetened version of a fruit drink. STATISTICAL ANALYSES PERFORMED A test of equivalence was run across all four flavors and separately for each flavor using two one-sided tests. RESULTS The data failed to demonstrate equivalence of the sugar-free and sugar-sweetened fruit drinks across all four flavors (P=0.51) or separately for each flavor. However, this was not because of a preference for sugar-sweetened drinks. The preference for sugar-free drinks overall and for each flavor was >50%. Although the lower bounds of the 90% CIs were within the range of equivalence (40% to 60%), the upper bounds were outside the range of equivalence (>60%). According to post hoc analyses, similar preferences were observed for Yup'ik and non-Yup'ik children, boys and girls, and children of different ages. CONCLUSIONS Taste preference findings suggest that sugar-free fruit drinks may be a well-tolerated alternative to sugar-sweetened fruit drinks for Yup'ik children in Alaska Native communities.

Abstract
Addressing the determinants of non-communicable diseases (NCDs) is challenged by aggressive market promotion by tobacco, alcohol and unhealthy food industries in emerging countries with fast economic development; and interference by these industries in government policies aimed at containing consumption of unhealthy products. This editorial reviews market promotion and industry interference and classifies them into four groups of tactics: (a) interfering with the legislative process; (b) using front groups to act on their behalf; (c) questioning the evidence of tobacco harm and the effectiveness of harm-reduction interventions; and (d) appearing responsible in the eyes of the public, journalists and policy-makers. Despite active implementation of the Framework Convention on Tobacco Control (FCTC), the tobacco, alcohol and unhealthy food industries use similar tactics to aggressively interfere in policies, with the tobacco industry being the most aggressive. Policy interference by industries are effective in the context of poor governance, rampant corruption, conflict of interest among political and government actors, and regulatory capture in all levels of countries from low- to high-income. In addressing these interferences, government requires the practice of good governance, effective mechanisms to counteract conflict of interests among political and policy actors, and prevention of regulatory capture. The World Health Organization (WHO) Framework of Engagement with non-State Actors can be applied to the country context when engaging private entities in the prevention and control of NCDs.

Abstract
OBJECTIVE To estimate the impact of the UK government's sugar reduction programme on child and adult obesity, adult disease burden, and healthcare costs. DESIGN Modelling study. SETTING Simulated scenario based on National Diet and Nutrition Survey waves 5 and 6, England. PARTICIPANTS 1508 survey respondents were used to model weight change among the population of England aged 4-80 years. MAIN OUTCOME MEASURES Calorie change, weight change, and body mass index change were estimated for children and adults. Impact on non-communicable disease incidence, quality adjusted life years, and healthcare costs were estimated for adults. Changes to disease burden were modelled with the PRIMEtime-CE Model, based on the 2014 population in England aged 18-80. RESULTS If the sugar reduction programme was achieved in its entirety and resulted in the planned sugar reduction, then the calorie reduction was estimated to be 25 kcal/day (1 kcal=4.18 kJ=0.00418 MJ) for 4-10 year olds (95% confidence interval 23 to 26), 25 kcal/day (24 to 28) for 11-18 year olds, and 19 kcal/day (17 to 20) for adults. The reduction in obesity could represent 5.5% of the baseline obese population of 4-10 year olds, 2.2% of obese 11-18 year olds, and 5.5% of obese 19-80 year olds. A modelled 51 729 quality adjusted life years (95% uncertainty interval 45 768 to 57 242) were saved over 10 years, including 154 550 (132 623 to 174 604) cases of diabetes and relating to a net healthcare saving of £285.8m (€332.5m, $373.5m; £249.7m to £319.8m). CONCLUSIONS The UK government's sugar reduction programme could reduce the burden of obesity and obesity related disease, provided that reductions in sugar levels and portion sizes do not prompt unanticipated changes in eating patterns or product formulation.

Abstract
Excess consumption of added sugars, especially from sugary drinks, poses a grave health threat to children and adolescents, disproportionately affecting children of minority and low-income communities. Public policies, such as those detailed in this statement, are needed to decrease child and adolescent consumption of added sugars and improve health.

Abstract
BACKGROUND The extent to which low-calorie sweeteners (LCSs) are helpful or harmful for weight management and metabolic health is unclear, because LCS effects may depend on the context in which they are consumed. OBJECTIVE To develop a conceptual framework for LCS consumption. METHODS Young adults ages 18-35 y, who reported LCS consumption, were recruited from a private, urban, university in the mid-Atlantic United States. Concept mapping, a mixed-method approach was used to identify, organize, and quantify determinants of LCS consumption. First, participants (n = 68) identified reasons for their LCS consumption through brainstorming; content analysis of those reasons identified 37 specific determinants of LCS consumption. Second, participants (n = 93) sorted all 37 determinants conceptually. Third, participants (n = 97) rated the extent to which each of the 37 determinants was reflective of their own consumption. Similarity matrices, multidimensional scaling, and hierarchical cluster analysis produced a series of 2-dimensional concept maps (SWEET MAPS). RESULTS The SWEET MAPS identified 37 determinants, organized within 8 factors reflective of 3 overarching motives: perceived health benefits, palatability, and accessibility of LCSs. At the determinant level, the most highly rated determinants that exceeded the boundary (rating >3.0) were: "I want something that tastes sweet," "I am trying to maintain/control my weight," "They contain fewer calories," "They are available," and "I want to save calories because I am eating a high-calorie meal." CONCLUSIONS LCS consumption is a function of many inter-related determinants spanning biological, psychological, and social domains. The SWEET MAPS are an important and novel use of concept mapping methods that can be used to inform the design and interpretation of future studies evaluating LCS effects.

Heliyon 2019; 5:e01357. [PMID: 30949605 PMCID: PMC6429811 DOI: 10.1016/j.heliyon.2019.e01357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2018] [Revised: 02/20/2019] [Accepted: 03/12/2019] [Indexed: 01/01/2023] Open
Abstract
Aims Although there is evidence linking sugar-sweetened beverage (SSB) intake with the development of cardio-metabolic diseases, the underlying mechanisms remain unclear. The current study therefore evaluated the effects of SSB consumption by establishing a unique in-house in vivo experimental model. Main methods Male Wistar rats were divided into two groups: a) one consuming a popular local SSB (SSB- Jive), and b) a control group (Control-water) for a period of three and six months (n = 6 per group), respectively. Rats were gavaged on a daily basis with an experimental dosage amounting to half a glass per day (in human terms) (SSB vs. water). Cardiac function was assessed at baseline (echocardiography) and following ex vivo ischemia-reperfusion of the isolated perfused working rat heart. Oral glucose tolerance tests and mitochondrial respiratory analyses were also performed. In addition, the role of non-oxidative glucose pathways (NOGPs), i.e. the polyol pathway, hexosamine biosynthetic pathway (HBP) and PKC were assessed. Key findings These data show that SSB intake: a) resulted in increased weight gain, but did not elicit major effects in terms of insulin resistance and cardiac function after three and six months, respectively; b) triggered myocardial NOGP activation after three months with a reversion after six months; and c) resulted in some impairment in mitochondrial respiratory capacity in response to fatty acid substrate supply after six months. Significance SSB intake did not result in cardiac dysfunction or insulin resistance. However, early changes at the molecular level may increase risk in the longer term.

A randomized home-based childhood obesity prevention pilot intervention has favourable effects on parental body composition: preliminary evidence from the Guelph Family Health Study. BMC OBESITY 2019; 6:10. [PMID: 30873285 PMCID: PMC6398255 DOI: 10.1186/s40608-019-0231-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Accepted: 01/31/2019] [Indexed: 12/11/2022]
Abstract
Background Home-based lifestyle behaviour interventions show promise for treating and preventing childhood obesity. According to family theories, engaging the entire family unit, including parents, to change their family behaviour and dynamics may be necessary to prevent the development of childhood obesity. However, little is known about how these interventions, which may change the family dynamics and weight-related behaviours of parents, affect weight outcomes in parents. Our objective was to examine the effect of a pilot home-based childhood obesity prevention intervention on measures of anthropometrics and body composition in Canadian parents. Methods Forty-four families with children aged 1.5–5 years were randomized to one of three groups: 4 home visits with a health educator, emails, and mailed incentives (4 HV); 2 home visits, emails, and mailed incentives (2 HV); or general health emails (control). Both the 2 HV and 4 HV intervention were conducted over a period of 6 months. Body composition and anthropometric outcomes were measured at baseline and at 6 months and 18 months from baseline. Results In parents with baseline body mass index (BMI) ≥ 25 kg/m2, the 2 HV group had significantly lower body mass and waist circumference at 6-month (CI = -5.85,-0.14 kg;-5.82,-0.30 respectively) and 18-month follow-up (CI = -7.57,-1.21 kg;-9.30,-2.50 cm respectively) when compared to control, and significantly lower BMI at 18-month follow-up when compared to control (CI = -2.59,-0.29 kg/m2). In parents with baseline BMI < 25 kg/m2, the 4 HV group had significantly lower percentage fat mass (CI = -3.94,-0.12%), while the 2 HV group had significantly lower body mass (CI = -2.56,-0.42 kg) and BMI (CI = -0.77,-0.08 kg/m2) at 6-month follow-up, both compared to control; these effects were not maintained at 18-month follow-up. Conclusions This study provides support that a home-based childhood obesity prevention intervention may improve weight outcomes among parents. Future research should explore how home-based interventions influence family behaviour and dynamics to impact weight outcomes in children and their parents. Trial registration Prospectively registered August 2014, clinical trial identifier NCT02223234.

Association of free sugar intake with blood pressure and obesity measures in Australian adults. Eur J Nutr 2019; 59:651-659.

Abstract
PURPOSE This study examined the association of free sugar (FS) intake with obesity measures and blood pressure (BP) among a nationally representative sample of Australian adults. METHODS Data from adults (weighted n = 5136) who completed 2 × 24-h recalls and had complete data for BP, waist circumference (WC), waist-to-height ratio (WHtR), and body mass index (BMI) were analyzed. Associations between percentage energy of FS from all food sources (%EFStotal), beverages only (%EFSbeverages), and non-beverages sources only (%EFSnon-beverages) and obesity measures and BP were examined using linear and non-linear regressions. Logistic regression was used to calculate the odds ratios (OR) of being classified as overweight and/or obese, having increased cardiometabolic risks, and elevated BP per 5% point increase in %EFStotal, %EFSbeverages, and %EFSnon-beverages. All regression analyses were adjusted for known socio-economic and lifestyle confounders. RESULTS %EFSbeverage was positively associated with BMI, WC, and WHtR (all p < 0.05), while %EFSnon-beverage was inversely associated with these outcomes. Increases in odds of having an undesirable WC/WHtR were found with increasing %EFSbeverages (OR per 5% point increase in %EFSbeverages: 1.19 for WC; 1.23 for WHtR, both p < 0.001). %EFStotal and %EFSnon-beverages were weakly and negatively associated with diastolic BP. A 5% point increase in %EFStotal and %EFSnon-beverage was associated with a 10-25% reduction in odds of having elevated BP. CONCLUSIONS Our results suggested that only a higher FS intake from beverages may be associated with obesity, and higher FS intake was associated with reduced odds of having elevated BP.

Abstract
BACKGROUND AND OBJECTIVES Investigations in older individuals suggest that adequate nutrition and physical activity are particularly important to skeletal muscle health; however, data in adolescents are scant and equivocal. The objective was to determine the associations among diet, physical activity and skeletal muscle mass in adolescents. METHODS We assessed diet with four to seven 24-h recalls and physical activity by accelerometry in 640 adolescents. Using total body measures of fat-free soft tissue mass and fat mass assessed by dual-energy X-ray absorptiometry, the skeletal muscle mass index (SMMI) was derived by adjusting fat-free soft tissue mass for fat mass in addition to height. RESULTS Skeletal muscle mass index (SMMI) was negatively associated with consumption of sugar-sweetened beverages (standardized beta coefficient [β] = -0.10, P = 0.001) and saturated fats (β = -0.28, P < 0.001). SMMI was positively associated with physical activity (moderate + vigorous) (β = 0.20, P < 0.001). In further analysis, we observed a significant interaction between physical activity and sugar-sweetened beverage intake on SMMI (P = 0.002). CONCLUSION Our study in adolescence suggests that physical activity and consumption of both sugar-sweetened beverages and saturated fats are associated with skeletal muscle mass. More importantly, our findings suggest that sugar-sweetened beverage intake may attenuate the beneficial effects of physical activity on skeletal muscle mass.

Abstract
OBJECTIVE To assess the association between intake of non-sugar sweeteners (NSS) and important health outcomes in generally healthy or overweight/obese adults and children. DESIGN Systematic review following standard Cochrane review methodology. DATA SOURCES Medline (Ovid), Embase, Cochrane CENTRAL, WHO International Clinical Trials Registry Platform, Clinicaltrials.gov, and reference lists of relevant publications. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Studies including generally healthy adults or children with or without overweight or obesity were eligible. Included study designs allowed for a direct comparison of no intake or lower intake of NSS with higher NSS intake. NSSs had to be clearly named, the dose had to be within the acceptable daily intake, and the intervention duration had to be at least seven days. MAIN OUTCOME MEASURES Body weight or body mass index, glycaemic control, oral health, eating behaviour, preference for sweet taste, cancer, cardiovascular disease, kidney disease, mood, behaviour, neurocognition, and adverse effects. RESULTS The search resulted in 13 941 unique records. Of 56 individual studies that provided data for this review, 35 were observational studies. In adults, evidence of very low and low certainty from a limited number of small studies indicated a small beneficial effect of NSSs on body mass index (mean difference -0.6, 95% confidence interval -1.19 to -0.01; two studies, n=174) and fasting blood glucose (-0.16 mmol/L, -0.26 to -0.06; two, n=52). Lower doses of NSSs were associated with lower weight gain (-0.09 kg, -0.13 to -0.05; one, n=17 934) compared with higher doses of NSSs (very low certainty of evidence). For all other outcomes, no differences were detected between the use and non-use of NSSs, or between different doses of NSSs. No evidence of any effect of NSSs was seen on overweight or obese adults or children actively trying to lose weight (very low to moderate certainty). In children, a smaller increase in body mass index z score was observed with NSS intake compared with sugar intake (-0.15, -0.17 to -0.12; two, n=528, moderate certainty of evidence), but no significant differences were observed in body weight (-0.60 kg, -1.33 to 0.14; two, n=467, low certainty of evidence), or between different doses of NSSs (very low to moderate certainty). CONCLUSIONS Most health outcomes did not seem to have differences between the NSS exposed and unexposed groups. Of the few studies identified for each outcome, most had few participants, were of short duration, and their methodological and reporting quality was limited; therefore, confidence in the reported results is limited. Future studies should assess the effects of NSSs with an appropriate intervention duration. Detailed descriptions of interventions, comparators, and outcomes should be included in all reports.

Abstract
OBJECTIVES To investigate the association of soft drink consumption and the intake of sugar from soft drinks with the prevalence of acne in adolescents. STUDY DESIGN This was a university-based epidemiologic investigation that included 8226 students who underwent health examinations and a questionnaire survey inquiring about the intake of soft drinks. Skin diseases were diagnosed by certificated dermatologists during the health examination. Two-level logistic and generalized additive models were used to estimate the associations, and aORs were presented as the effect size. RESULTS A total of 8197 student survey responses were analyzed. Frequent intake (≥7 times per week) of carbonated sodas (aOR 1.61, 95% CI 0.96-2.72), sweetened tea drinks (aOR 2.52, 95% CI 1.43-4.43), and fruit-flavored drinks (aOR 1.90, 95% CI 1.18-3.07) was associated with moderate-to-severe acne after adjustments for confounders. The occasional intake of fruit-flavored drinks (1-2 times per week) had a weak protective effect on acne (aOR 0.86, 95% CI 0.74-0.99). The intake of sugar from any soft drinks showed a nonlinear association with acne (P < .01), and sugar intake ≥100 g/d was significantly associated with moderate-to-severe acne (aOR 3.12, 95% CI 1.80-5.41). CONCLUSIONS Daily soft drink consumption significantly increases the risk of moderate-to-severe acne in adolescents, especially when the sugar intake from any type of soft drink exceeds 100 g per day.

Abstract
INTRODUCTION Excess weight is a risk factor for systemic and oral diseases. Since dental professionals are already involved in imparting overall health messages when certain conditions impact oral health, it should make sense that they also deliver related health messages such as promoting the maintenance of healthy weight for patients. OBJECTIVES This study evaluated the perceptions of adult patients attending private dental clinics on healthy weight promotion by dental professionals. METHODS A cross-sectional multicenter survey was designed and set in four private dental clinics (London/Hampshire) between April and July 2015. All eligible patients (≥ 18 years) completed a questionnaire. Body Mass Index (BMI; kg/m2) was calculated from height and weight measurements. Questionnaire content was centred on patient perceptions of 6 domains with the primary domain as to whether patients would accept healthy weight promotion by dental professionals. RESULTS 213 adults (aged 20-85 years) participated in this study and 58.2% were females. Although the overwhelming majority endorsed healthy weight promotion by the dental team, the overweight/obese were significantly more sensitive (BMI screening χ2 trend = 6.840, p = 0.009; healthy weight information χ2 trend = 6.231, p = 0.013). Awareness of risk of periodontitis, carcinoma and overall adverse health outcomes associated with overweight or obesity was low. CONCLUSION The study cohort was well primed for healthy weight advice. Routine healthy weight promotion and BMI screening should be considered in the private dental clinic settings. CLINICAL SIGNIFICANCE This is an opportunity to collaborate with other health care professionals to support overall health monitoring/advice; a common risk factor strategy as recommended by the WHO. Future research is merited for this new initiative particularly perceptions of: dental teams' on healthy weight management, longitudinal interventions, NHS, children/parents and separate obese groups.

Abstract
Pediatric nonalcoholic fatty liver disease (NAFLD) is the most common cause of liver disease in children. The spectrum of NAFLD ranges from steatosis to nonalcoholic steatohepatitis (NASH) to fibrosis. Obesity rates in children continue to rise and, as a result, NAFLD in children is becoming more prevalent. The pathophysiology, natural history, and progression of disease are still being elucidated but NAFLD/NASH in children may represent a more severe phenotype that will benefit from early identification and management.

Abstract
BACKGROUND Sugar-sweetened beverages and maternal weight are strong drivers of child obesity, but few studies have targeted these risk factors as an obesity prevention strategy in children. OBJECTIVE The objective of this study was to test the efficacy of a smartphone-delivered intervention to reduce parent-provided sugar-sweetened beverage and juice (SSB/juice) consumption among children ages 3-5 and maternal weight. METHODS Mothers with overweight or obesity, who had a child ages 3-5 that consumed at least 12 fl. oz./day of SSB/juice (N = 51 dyads) were randomized to the Smart Moms group that received one group session, lessons on a mobile website, and text messages, or to a waitlist control group. Mothers self-monitored their children's beverages in addition to their own beverages, high-calorie foods, and weight. Assessments at baseline, 3, and 6 months included dietary recalls to measure SSB/juice intake and objectively measured maternal weight. RESULTS Using linear mixed models controlling for baseline values, child age and race, there was a greater reduction in child SSB/juice in Smart Moms compared with control at 6 months (-9.7 oz./day vs. 1.7 oz./day, p < .01). Mothers in Smart Moms lost 2.4 kg at 6 months compared with a 0.9-kg gain in the control group (p < .01). CONCLUSIONS An intervention delivered using mHealth technologies can target mothers to change child dietary behaviours and improve maternal weight, which suggests a novel approach to family-based obesity prevention.

Abstract
Excessive consumption of carbonated drinks contributes to the dietary surplus of carbohydrates, and is a main driver of the obesity epidemic in the USA. From a public health standpoint, it is therefore crucial to develop strategies that enable individuals to regulate this calorie-rich, but nutrient-poor food intake. However, conservative medical approaches to this end have met with limited success. Using a pharmacological strategy to eliminate the effervescent aspect of carbonated drinks, we report significant weight loss in a patient with long-standing obesity. Administration of low-dose acetazolamide, a carbonic anhydrase inhibitor, resulted in altered taste of carbonation, and in turn a marked reduction in the patient’s carbonated drink intake and the loss of almost 1 kg of body weight per week. The pharmacological intervention also resulted in appetite suppression, which might synergistically contribute to weight loss. These findings point to the use of low-dose acetazolamide as a novel weight reduction strategy.

Abstract
Sugar-sweetened beverages (SSBs) increase risk of cardiometabolic disease. Young people consume the largest amounts of SSBs and have experienced the greatest relative gains in obesity in the past several decades. There is evidence of addictive properties of both caffeine and sugar, the primary ingredients in SSBs, but little research into such properties of SSBs in naturally occurring consumption patterns. Thus, in this exploratory study, we sought to examine potentially addictive properties of SSBs during a 3-day SSB cessation intervention in overweight and obese adolescents who typically consume ≥3 SSBs daily. Participants (n = 25) were aged 13-18 years, mostly female (72%), and African American (56%) or Hispanic (16%) with a BMI≥95th percenttile (76%). Withdrawal symptoms and SSB craving were assessed approximately 1-week apart, during both regular SSB consumption and a 3-day period of SSB cessation in which participants were instructed to drink only plain milk and water. During SSB cessation, adolescents reported increased SSB cravings and headache and decreased motivation, contentment, ability to concentrate, and overall well-being (uncorrected Ps < 0.05). After controlling the false discovery rate, changes in motivation, craving, and well-being remained significant (corrected Ps < 0.05). Using 24-hr recalls and drink journals, participants reported lower total daily consumption of sugar (-80 g) and added sugar (-16 g) (Ps < 0.001) during cessation. This study provides preliminary evidence of withdrawal symptoms and increased SSB cravings during cessation in a diverse population of overweight or obese adolescents.

Abstract
OBJECTIVE The aim of this study is to review the control of energy balance and outline some causes of and remedies for excessive energy intake. METHODS A narrative review was conducted. RESULTS There is negative feedback control of energy intake and body weight, but, nonetheless, energy intake is only loosely coupled with energy expenditure. Consequently, we are vulnerable to eating in excess of energy requirements. In this context, energy density, portion size, and habitual meal patterns have strong influences on energy intake and, accordingly, can be targeted to reduce energy intake. For example, energy density can be reduced without much affecting food reward (approximately the pleasure gained from eating) because their relationship is such that reward value is affected relatively little by increments in energy density above 1.5 kcal/g. This and other strategies that increase reward per calorie eaten may be superior to increasing the satiety effect of products because fullness is not inherently rewarding. Low-calorie sweeteners provide a means to reduce energy density while largely preserving food or beverage reward value. Consistent with this, consumption of low-calorie sweeteners compared with consumption of sugars has been found to reduce energy intake and body weight. CONCLUSIONS Understanding what causes excessive eating also provides insights into how to combat this problem.

Abstract
Low-calorie sweeteners (LCS) are found in a variety of foods and beverages, yet their role in diet, weight, and obesity-related chronic disease is controversial. This article summarizes proceedings from one of four presentations during a preconference session entitled "Low-Calorie Sweeteners and Weight Management," which took place at the 2017 Obesity Society Annual Meeting in Washington, District of Columbia. The objective of this brief review is to summarize findings of observational and interventional studies of LCS effects on weight and metabolic health and to provide potential explanations for their discrepant results. Key research priorities for advancing the understanding of the role of LCS in weight and chronic disease are also discussed. The existing literature suggests that LCS consumption is consistently associated with obesity, diabetes, and related cardiometabolic conditions in observational studies. Although several plausible mechanisms have been proposed to explain these associations and have received considerable support in cellular and rodent models, the relevance of these mechanisms to humans has yet to be confirmed. Meanwhile, randomized controlled trials demonstrate that NNS may benefit weight loss and weight maintenance. This is the case particularly when LCS are administered in the context of behavioral weight loss support and are consumed knowingly by habitual LCS consumers. Although these findings suggest that LCS may be useful for weight control among those cognitively engaged in weight loss and who are aware of their LCS consumption, LCS administration in these studies does not reflect typical consumption. Furthermore, few interventional studies have assessed the role of LCS on metabolic outcomes other than body weight. Additional factors must be considered before recommending LCS for weight management and chronic disease prevention and further study of LCS effects on a variety of cardiometabolic outcomes, including visceral adiposity and glucose homeostasis is warranted.

Abstract
Lifestyle is a complex concept that includes aspects external to ourselves that can modulate and influence our health. The knowledge of the relationship between lifestyle and cardiovascular risk does not attain the level of evidence achieved with clinical trials with drugs, because clinical studies are scarce and mainly of observational nature, albeit based on large cohorts. Nutritional epidemiology has the added difficulty of being based mostly on subjective dietary recall methods to ascertain nutrient and food intake over time, with the additional problems of incomplete data collection, variable measurements of adherence due to seasonal and geographical differences in food composition, and the changing eating behavior that human beings have over time. The purpose of this document is to carry out an updated and hierarchical review of the relationship between lifestyle and cardiovascular disease based on current evidence, paying attention to three aspects that are of great pathogenic importance and are directly modifiable: physical activity, tobacco consumption, and diet. With this, we intend to update the knowledge on this relationship, construct evidence-based recommendations, and provide a simple tool for clinical practice especially directed to health professionals involved in the care of people at cardiovascular risk, defining simple and easy strategies for individuals who receive advice for the primary and secondary prevention of cardiovascular diseases.

Abstract
Background and aims: Inappropriate or imbalanced consumption of foods may lead to several health problems, especially among adolescents, the complications of which will remain for several years. This study aimed to investigate perceptions, self-efficacy, and the status of junk food consumption and their relationship with demographic variables in female high school students in Shahrekord using Health Belief Model (HBM). Methods: This is a descriptive- analytic study conducted in academic year 2016-2017. Three hundred twenty-three adolescent girls (second grade high school students of Shahrekord) were selected through cluster sampling method. A standard questionnaire, according to the structures of health belief model (perceived susceptibility, severity, benefits, barriers, and self-efficacy) and a checklist for assessment of junk food consumption was used to collect data. The obtained data were analyzed using SPSS software, version 16 and descriptive as well as analytic tests. Results: The mean age of the participants was 16.03 ± 1.24 years old. The mean scores of knowledge, perceived susceptibility, severity, benefits, barriers, and self-efficacy in proper consumption of junk foods were 55.66 ± 20.95; the mean frequency of junk food consumption among the students was reported to be 6.17 ± 3.18 times. There was a significantly inverse associations among perceived self-efficacy, severity, and benefit and junk food consumption. The mean frequency of junk food consumption in the schools under investigation was 6.67 ± 3.62 times. Conclusion: Considering the consumption of relatively high amounts of junk foods, the students’ low levels of knowledge and perception and the effect of peer groups, it is necessary to promote students’ nutritional knowledge, change adolescents’ diet, and pay more attention to packaging of healthy foods and making them more attractive

Abstract
AbstractObjectiveExperts recommend that products containing artificial sweeteners are not marketed to children or sold at schools. The present study aimed to provide a baseline assessment of the extent to which state laws and local school district wellness policies (LWP) address restrictions on the use of artificial sweeteners in competitive foods and beverages (CF&B) sold at schools.DesignA descriptive, cross-sectional study of policies in place for the 2014–15 school year.SettingData were collected on laws in all fifty states and Washington, DC. LWP were compiled for 496/518 school food authorities (SFA) for which data were collected as part of the US Department of Agriculture’s School Nutrition and Meal Cost Study.SubjectsState laws and LWP respectively were coded on a 0–3 ordinal scale for the strength of their restrictions on artificial sweeteners in CF&B sold in each of five CF&B venues, separately by grade level. Prevalence of state laws and LWP for SFA nationwide was computed.ResultsThirteen states addressed the use of artificial sweeteners. Six states addressed the use of artificial sweeteners in both CF&B. District-level artificial sweetener policies were most frequently addressed for beverages in elementary schools’ vending machines. District policies also were more likely to address artificial sweeteners in states with laws addressing artificial sweeteners.ConclusionsMost state laws and LWP do not address artificial sweeteners in CF&B. This is not surprising given the Food and Drug Administration has approved eight artificial sweeteners for consumption and the Smart Snacks regulation does not limit artificial sweeteners for CF&B.

Pathways and mechanisms linking dietary components to cardiometabolic disease: thinking beyond calories. Obes Rev 2018; 19:1205-1235. [PMID: 29761610 PMCID: PMC6530989 DOI: 10.1111/obr.12699] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Revised: 03/09/2018] [Accepted: 03/31/2018] [Indexed: 12/11/2022]
Abstract
Calories from any food have the potential to increase risk for obesity and cardiometabolic disease because all calories can directly contribute to positive energy balance and fat gain. However, various dietary components or patterns may promote obesity and cardiometabolic disease by additional mechanisms that are not mediated solely by caloric content. Researchers explored this topic at the 2017 CrossFit Foundation Academic Conference 'Diet and Cardiometabolic Health - Beyond Calories', and this paper summarizes the presentations and follow-up discussions. Regarding the health effects of dietary fat, sugar and non-nutritive sweeteners, it is concluded that food-specific saturated fatty acids and sugar-sweetened beverages promote cardiometabolic diseases by mechanisms that are additional to their contribution of calories to positive energy balance and that aspartame does not promote weight gain. The challenges involved in conducting and interpreting clinical nutritional research, which preclude more extensive conclusions, are detailed. Emerging research is presented exploring the possibility that responses to certain dietary components/patterns are influenced by the metabolic status, developmental period or genotype of the individual; by the responsiveness of brain regions associated with reward to food cues; or by the microbiome. More research regarding these potential 'beyond calories' mechanisms may lead to new strategies for attenuating the obesity crisis.

Consumption of artificial sweetened beverages associated with adiposity and increasing HbA1c in Hispanic youth. Clin Obes 2018; 8:236-243. [PMID: 29896938 PMCID: PMC6055860 DOI: 10.1111/cob.12260] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 04/24/2018] [Accepted: 05/08/2018] [Indexed: 12/04/2022]
Abstract
Research examining the impact of artificial sweetened beverages (ASBs) on obesity and metabolic diseases in adolescents is limited. The overall goal is to examine the longitudinal effects of ASBs on changes in adiposity and metabolic parameters in Hispanic adolescents. Longitudinal cohort with 98 Hispanics (12-18 years) who were overweight or had obesity with the following data at baseline and 1-year later: anthropometrics, diet (24-h recalls), body composition (DXA), glucose and insulin dynamics (oral glucose tolerance and frequently sampled intravenous glucose tolerance test) and fasting lipids. Repeated measures analyses of covariance assessed changes over time between control (no ASBs at either visit), ASB initiators (no ASBs at baseline/ASBs at 1-year) and chronic ASB consumers (ASBs at both visits). ASB initiators (n = 14) and chronic ASB consumers (n = 9) compared to control (n = 75) had higher total body fat at baseline and 1-year (P = 0.05 for group effect). Chronic ASB consumers had a 6% increase in haemoglobin A1c, 34% increase in energy intake (kcal d-1 ) and 39% increase in carbohydrate intake (g d-1 ) over time, while control and ASB initiators maintained (P < 0.05 for group-by-time interactions). These results do not support promoting ASBs as a strategy for adiposity loss or to improve metabolic health.

Abstract
Beverage consumption habits are associated with weight outcomes for children and adolescents. Many studies have examined youth's beverage consumption, but little is known about what methods are commonly used to assess youth beverage consumption and whether these strategies are valid and reliable. This study aimed to systematically review articles assessing beverage consumption among children and adolescents. We searched PubMed and Scopus for English-language articles published between February 2007 and February 2017 that measured and reported on American youth's (ages 2-18 years) beverage consumption. Searches yielded 17,165 articles, of which 589 articles describing 615 measures were extracted. We examined the types of assessment methods used, characteristics of these methods (e.g. validity, reliability, and literacy level), characteristics of study samples, and beverages assessed. The most common assessment methods were questionnaires/screeners (used by 65.4% of articles) and recalls (24.4%). About three-quarters of articles did not address validity (70.5%) or reliability (79.5%) of any measures used. Study populations were diverse: 54.7% of articles included low-income children, and 90.2% included non-White children. The most commonly assessed beverage category was sugar-sweetened beverages. Findings suggest that improved measurement techniques and reporting are both needed to track progress towards a goal of ensuring all youth have healthy beverage consumption.

Abstract
Despite intensive research, the causes of the obesity epidemic remain incompletely understood and conventional calorie-restricted diets continue to lack long-term efficacy. According to the carbohydrate-insulin model (CIM) of obesity, recent increases in the consumption of processed, high-glycemic-load carbohydrates produce hormonal changes that promote calorie deposition in adipose tissue, exacerbate hunger, and lower energy expenditure. Basic and genetic research provides mechanistic evidence in support of the CIM. In animals, dietary composition has been clearly demonstrated to affect metabolism and body composition, independently of calorie intake, consistent with CIM predictions. Meta-analyses of behavioral trials report greater weight loss with reduced-glycemic load vs low-fat diets, though these studies characteristically suffer from poor long-term compliance. Feeding studies have lacked the rigor and duration to test the CIM, but the longest such studies tend to show metabolic advantages for low-glycemic load vs low-fat diets. Beyond the type and amount of carbohydrate consumed, the CIM provides a conceptual framework for understanding how many dietary and nondietary exposures might alter hormones, metabolism, and adipocyte biology in ways that could predispose to obesity. Pending definitive studies, the principles of a low-glycemic load diet offer a practical alternative to the conventional focus on dietary fat and calorie restriction.

Abstract
The prevalence of nonalcoholic fatty liver disease (NAFLD) has increased substantially in the past two decades and NAFLD has now become the most common cause of chronic liver disease in children and adolescents. NAFLD is a broad clinicopathologic spectrum ranging from simple steatosis to varying degrees of necroinflammation called nonalcoholic steatohepatitis (NASH), leading to fibrosis and subsequently to cirrhosis. Despite the increasing prevalence and progressive nature of NAFLD even among children, therapy for NAFLD in both adults and children are limited. Weight loss remains the only consistently effective therapy for NAFLD. Pharmacologic options are even more limited in children than in adults with NAFLD. Vitamin E has been shown to be effective in improving histology in children with NASH. Few pharmacologic options such as metformin, probiotics, omega-3 fatty acids, and cysteamine bitartrate have been studied in children, with limited beneficial effects. However, these studies are limited by small sample size and heterogeneity of outcome assessment after treatment. Recent studies show promising results with bariatric surgery with regards to weight loss and improvement in liver histology in adolescents with NAFLD. In this review article, we discuss epidemiology, pathophysiology, and extrahepatic comorbidities of pediatric NAFLD and review existing therapeutic options for children with NAFLD. We also review novel therapeutic strategies studied in adults that could potentially be studied in children in the future.
