“…The 2 dietary behavior interventions did not have a significant effect on mean BMI (50,51). All PA studies, except for one (55), found a significant effect on BMI or BMI z score for the overall sample (59,60) or for girls (56,57). No ES could be calculated for these studies.…”

“…Diet-only interventions mainly used nutrition education promoting healthy diets as a key intervention strategy (48,49,51); one study was a breakfast program (50). Eight of 10 PA interventions provided additional physical-education sessions ranging from 50 to 315 min extra per week (52)(53)(54)(56)(57)(58)(59)(60). Except for one study not reporting these data (47), these studies integrated their additional sessions into the existing curriculum.…”

Background: The prevalence of childhood obesity is increasing rapidly in low-and middle-income countries, and informed policies to tackle the problem must be defined. Objective: We systematically reviewed the evidence on the effectiveness of school-based interventions targeting dietary behavior and/or physical activity for the primary prevention of obesity in children and adolescents aged 6-18 y in low-and middle-income countries. Design: We searched the MEDLINE, EMBASE, Web of Science, CENTRAL, ERIC, Cochrane Library, and Centre for Reviews and Dissemination databases for peer-reviewed controlled studies published in English, Spanish, French, German, or Dutch between January 1990 and July 2011. The quality of the included studies was appraised independently by 2 authors who used the Effective Public Health Practice Project tool. Results: From a total of 7218 unique references, we retained 22 studies. Most of the interventions (82%) had a positive effect on dietary behavior and physical activity behavior (effect size ranged from 20.48 to 1.61). BMI decreased in 8 studies (effect size ranged from 20.7 to 0.0). Effective interventions targeted both diet and physical activity, involved multiple stakeholders, and integrated educational activities into the school curriculum. Conclusions: School-based interventions have the potential to improve dietary and physical activity behavior and to prevent unhealthy body weights in low-and middle-income countries. To reach their full potential, interventions should conduct process evaluations to document program implementation. The effect and the pathways through which interventions have this effect need to be better documented through rigorous evaluation studies.Am J Clin Nutr 2012;96:415-38.

“…One aspect of childhood obesity is low levels of physical activity. [6][7][8][9][10] With the progressive decline in school physical activity participation coupled with declining numbers of physical education teachers, 7 there is growing interest in the potential role of stimulating physical activity during routine lessons. In adults, this can be achieved by using standing desks without being detrimental to workplace performance.…”

Background. In this pilot study, the authors aimed to examine the implementation of standing desks on classroom performance and behavior. They also examined how the standing desks affected in-class physical activity and body mass index. Methods. Eight sixth graders from Hope Lutheran elementary school participated in the study (age 11.3 ± 0.5 years). Baseline and 8-month postintervention measures were step counts using (W4L Classic pedometers), height, weight, and behavioral markers. Results. Data showed that there were no statistically significant changes in the participants’ body mass index (19.4 kg/m2 vs 19.3 kg/m2), step counts (1886 steps vs 2248 steps), and behavioral markers including classroom management, concentration, and discomfort. Height and weight changes were significant and are attributed to the normal growth rate associated with the age of the participants (146.8 cm vs 151.8 cm, P < .0001; 41.4 kg vs 44.5 kg, P > .0007). Conclusions. It is feasible to integrate standing desks into a classroom without negative effects. Although the authors observed over a 19% increase in pedometer activity, it was not statistically significant. This highlights the importance for larger experimental groups and the use of more advanced physical activity tracking and body composition technologies.

“…Childhood overweight and obesity not only affect children's physical and mental development (Li et al, 2007), but also directly threaten their quality of life in adulthood (Webitsch, 2000). Of people who are overweight, 75.9% have at least one metabolic abnormality and 20.4% have metabolic syndrome (Li et al, 2010).…”
