    ABSTRACT: Nutritively sweetened beverages (NSBs) may play a role in the obesity epidemic. We abstracted data from randomized controlled trials (RCTs) and evidence-based reviews through January 2009 concerning effects of consumption of NSBs on changes in body weight and adiposity. Studies included were those (i) conducted in humans; (ii) lasting at least 3 weeks; (iii) incorporating random assignment of subjects to conditions that differed only in the consumption of NSBs and (iv) including an adiposity indicator as an outcome. Twelve studies met the inclusion criteria. Meta-analysis of six studies that added NSBs to persons' diets showed dose-dependent increases in weight. Contrarily, meta-analysis of studies that attempted to reduce NSB consumption consistently showed no effect on body mass index (BMI) when all subjects were considered. Meta-analysis of studies providing access to results separately for subjects overweight at baseline showed a significant effect of a roughly 0.35 standard deviations lesser BMI change (i.e. more weight loss or less weight gain) relative to controls. The current evidence does not demonstrate conclusively that NSB consumption has uniquely contributed to obesity or that reducing NSB consumption will reduce BMI levels in general. We recommend an adequately powered RCT with overweight persons, for whom there is suggestive evidence of an effect.

    ABSTRACT: We aimed to develop a cost-free and sustainable program to influence healthier eating decisions during elementary school lunch. Baseline food and beverage choices were assessed for 9 days during lunch service at two racially and economically diverse elementary schools in Spartanburg County, SC, USA. After being informed that the labeled items on the daily lunch menu represented the healthiest choice, students were allowed to ring a call bell in the cafeteria for public recognition when they chose all of the identified healthiest food and beverage items during lunch service. Using menus matched to the baseline phase, food and beverage choices were measured during a 9-day intervention phase. After 30 days, food and beverage choices were reassessed during a 3-day follow-up phase. Healthiest food & beverage choices increased 49% with >60% of students choosing non-flavored milk over flavored milk during the intervention phase. There was no difference in the success of the program between the two schools. The program continued and healthy eating decisions were significantly sustained at a 30-day follow-up assessment. Public recognition through bell ringing appears to be an effective practice to sustain increases in healthy eating decisions during elementary school lunch and warrants expansion to larger scale, longitudinal trials.

    ABSTRACT: Background/aims: In adolescents, overweight and obesity are associated with an increased cardiovascular risk. The aim of this study was to determine the impact of a school-based nutritional education program (NEP) on lifestyle changes in Spanish adolescents. Methods: We selected 263 secondary school students (127 males) aged 12-16 years from Granada (Spain), who were followed up throughout 1 school year (2009-2010). At the beginning and end of the school year, data were gathered on the food consumption frequency, and anthropometric and biochemical profile. The NEP comprised a class on nutritional recommendations every 15 days, and administration of a daily breakfast of 275-350 kcal. Results: After the intervention, the prevalence of overweight and obesity decreased among both male and female students (p < 0.001) and there was also a global reduction in the prevalence of the metabolic syndrome (MS) from 32.2 to 19.7% (p < 0.001); in addition, body mass index was significantly decreased in normal weight, overweight and obesity groups (p = 0.001 and p = 0.02, respectively), and high-density-lipoprotein cholesterol and lean body mass was increased in all groups (p = 0.001). Conclusion: The NEP achieved a medium-term reduction in the prevalence of overweight and obesity and had a significant and positive effect on MS components in all groups.
