Abstract
PURPOSE A healthy diet is fundamental for healthy growth and for future disease prevention. However, scientific consensus on how to compose healthy diets for children has not been established. Therefore, a systematic review and meta-analysis was performed to investigate if an independent effect exists between foods, beverages or the composition of macronutrients and body composition in children and adolescents. METHODS A systematic search was performed in four databases up to July 2021. A systematic review of randomized controlled studies (RCTs) and meta-analyses were carried out by extracting mean difference (MDs) and standard deviation (SD) and performed using the random effect model. RESULTS Sixteen RCTs met inclusion criteria. Beyond dairy, sugar-sweetened beverages and macronutrient composition, no trials were identified for other food groups. Based on five RCTs (n:5), a higher-dairy diet was found to reduce body fat percentage - 0.47 [- 0.92, - 0.03] (p = 0.04). A higher-dairy diet was also found to increase lean body mass (kg) 0.34 [0.06, 0.62] (p = 0.02) (n:2), but did not affect BMI z-score - 0.05 [- 0.16, 0.06] (p = 0.39) (n:4). Substituting sugar-sweetened beverage with non-caloric beverages or flavored milk reduced body fat percentage (- 0.70 [- 0.78, - 0.62] (p < 0.001)) (n:3) but did not change BMI z-score (- 0.05 [- 0.20, 0.09] (p = 0.48)) (n:2). No significant effects were found between different macronutrient compositions and BMI z-score or body fat percentage. CONCLUSION Changes in diet from low to higher-dairy consumption and from sugar-sweetened beverages to non-caloric beverages or flavored milk resulted in favorable changes in body composition among children and adolescents. Eligible studies investigating other foods are lacking. TRIAL REGISTRATION PROSPERO registration number (CRD42020173201).

Sugar-sweetened beverage consumption and weight gain in children and adults: a systematic review and meta-analysis of prospective cohort studies and randomized controlled trials. Am J Clin Nutr 2023; 117:160-174. [PMID: 36789935 DOI: 10.1016/j.ajcnut.2022.11.008] [Citation(s) in RCA: 16] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 11/02/2022] [Accepted: 11/10/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Sugar-sweetened beverages (SSBs) have been implicated in fueling the obesity epidemic. OBJECTIVES This study aimed to update a synthesis of the evidence on SSBs and weight gain in children and adults. METHODS MEDLINE, Embase, and Cochrane databases were searched through September 8, 2022, for prospective cohort studies and randomized controlled trials (RCTs) that evaluated intake of SSBs in relation to BMI and body weight in children and adults, respectively. Eligible interventions were compared against a noncaloric control. Study-level estimates were pooled using random-effects meta-analysis and presented as β-coefficients with 95% CIs for cohorts and weighted mean differences (MDs) with 95% CIs for RCTs. RESULTS We identified 85 articles including 48 in children (40 cohorts, n = 91,713; 8 RCTs, n = 2783) and 37 in adults (21 cohorts, n = 448,661; 16 RCTs, n = 1343). Among cohort studies, each serving/day increase in SSB intake was associated with a 0.07-kg/m2 (95% CI: 0.04 kg/m2, 0.10 kg/m2) higher BMI in children and a 0.42-kg (95% CI: 0.26 kg, 0.58 kg) higher body weight in adults. RCTs in children indicated less BMI gain with SSB reduction interventions compared with control (MD: -0.21 kg/m2; 95% CI: -0.40 kg/m2, -0.01 kg/m2). In adults, randomization to addition of SSBs to the diet led to greater body weight gain (MD: 0.83 kg; 95% CI: 0.47 kg, 1.19 kg), and subtraction of SSBs led to weight loss (MD: -0.49 kg; 95% CI: -0.66 kg, -0.32 kg) compared with the control groups. A positive linear dose-response association between SSB consumption and weight gain was found in all outcomes assessed. CONCLUSIONS Our updated systematic review and meta-analysis expands on prior evidence to confirm that SSB consumption promotes higher BMI and body weight in both children and adults, underscoring the importance of dietary guidance and public policy strategies to limit intake. This meta-analysis was registered at the International Prospective Register of Systematic Reviews as CRD42020209915.

Abstract
Obesity is becoming increasingly prevalent in paediatric populations worldwide. In addition to increasing prevalence, the severity of obesity is also continuing to rise. Taken together, these findings demonstrate a worrying trend and highlight one of the most significant challenges to public health. Childhood obesity affects multiple organs in the body and is associated with both significant morbidity and ultimately premature mortality. The prevalence of complications associated with obesity, including dyslipidaemia, hypertension, fatty liver disease and psychosocial complications are becoming increasingly prevalent within the paediatric populations. Treatment guidelines currently focus on intervention with lifestyle and behavioural modifications, with pharmacotherapy and surgery reserved for patients who are refractory to such treatment. Research into adult obesity has established pharmacological novel therapies, which have been approved and established in clinical practice; however, the research and implementation of such therapies in paediatric populations have been lagging behind. Despite the relative lack of widespread research in comparison to the adult population, newer therapies are being trialled, which should allow a greater availability of treatment options for childhood obesity in the future. This review summarizes the current evidence for the management of obesity in terms of medical and surgical options. Both future therapeutic agents and those which cause weight loss but have an alternative indication are also included and discussed as part of the review. The review summarizes the most recent research for each intervention and demonstrates the potential efficacy and limitations of each treatment option.

Abstract
American children frequently consume candy and, in excess, this may contribute to poor diets with attendant effects on obesity risk. Despite the ubiquity of candy in children's diets, parental concern about children's candy intake, and the diversity of confectionery products available, very little is known about how children and their parents conceptualize candy. Card sorting tasks offer a novel and visual technique to explore and compare an individuals' perceptions of foods and are useful where literacy is limited (e.g. young children). This study aimed to understand and compare how young school-aged children and parents categorize various candy products using a photo card sorting task. In individual laboratory sessions, children (n = 42, 5 to 8 years old) and parents (n = 35) categorized 51 types of candy based on their similarity. A cluster analysis showed that parents created more categories of candies than children (11 versus 8). For example, parents distinguished between candied fruit and candied nuts, whereas children tended to collapse these categories. However, 7 clusters were virtually identical between parents and children (93% similarity). The findings from this study can inform the measurement of candy intake and the development of education materials targeted towards parent feeding around candy.

Abstract
OBJECTIVE Energy intake is regulated by overlapping homeostatic and hedonic systems. Consumption of palatable foods has been implicated in weight gain, but this assumes that homeostatic control systems do not accurately detect this hedonically driven energy intake. This study tested this assumption, hypothesizing that satiated rats would reduce their voluntary food intake and maintain a stable body weight after consuming a palatable food. METHODS Lean rats or rats previously exposed to an obesogenic diet were schedule-fed with fixed or varying amounts of palatable sweetened condensed milk (SCM) daily, and their voluntary energy intake and body weight were monitored. RESULTS During scheduled feeding of SCM, rats voluntarily reduced bland food consumption and maintained a stable body weight. This behavior was also seen in rats with access to an obesogenic diet and was independent of the predictability of SCM access. However, lean rats offered large amounts of SCM showed an increase in total energy intake. To test whether a nutrient deficiency drove this under-compensatory behavior, SCM was enriched with protein. However, no effect was seen on voluntary energy intake. CONCLUSIONS In schedule-fed rats, compensatory reductions in voluntary energy intake were seen, but under-compensation was observed if large amounts of SCM were consumed.
