“…A similar result was also observed by Katz 32 for combined interventions and decreased body mass with SMD: -0.29 (95%CI -0.45;-0.14) among students. This suggests that strategies to reduce and prevent obesity should focus on dietary consumption patterns and caloric expenditure through physical activity, aspects that should be prioritized in the planning of public policies for health.…”

OBJECTIVE:To evaluate the effect of intervention programs using nutritional education, physical activity or both on the reduction of body mass index in school-age students. METHODS:The systematic review with meta-analysis included randomized controlled studies available from the following electronic databases for the years 1998 to 2010: PubMed, Lilacs, Embase, Scopus, Web of Science and Cochrane Library. The descriptors were: randomized controlled trial, overweight, obesity, body mass index, child, adolescent, physical activity, nutrition education and Schools. A weighted average was based on the standardized means difference and used a 95% confi dence interval. The inconsistency test was utilized to evaluate the heterogeneity of studies. RESULTS:Initially, 995 studies were identifi ed, of which 23 were included, and 3 meta-analyses were performed. Isolated physical activity interventions did not present a signifi cant reduction in body mass index, with a standardized mean difference of -0.02 (95%CI: -0.08; 0.04). A similar result (n= 3,524) was observed in the isolated interventions of nutritional education, with a standardized mean difference of -0.03 (95%CI: -0.10; 0.04).When the interventions with physical activity and nutritional education were combined, the result of the meta-analysis (n= 9,997) presented a statistically signifi cant effect in the reduction of body mass index in school-age students, with a standardized mean difference: -0.37 (95%CI: -0.63; -0.12). CONCLUSIONS:The interventions that combined physical activity and nutritional education had more positive effects in the reduction of body mass index among school-age students than when they were applied individually.

“…En estas estrategias se incorporan a maestros y padres de familia. En este tenor, los programas de promoción de AF en escolares reportados en revisiones sistemáticas indican un aumento en la duración de la AF, así como una disminución en el tiempo utilizado para ver la televisión tras la ejecución de estrategias educativas (García & Hernández, 2011;Katz, 2009;Medina-Blanco, Jiménez-Cruz, Pérez-Morales, Armendáriz-Anguiano & Bacardí-Gascón, 2011;Strawser & Wachob, 2016).…”

Promoción de la actividad física en niños del norte de México: efectividad de una intervención educativa RESUMEN La epidemia de obesidad infantil ha motivado la implementación de intervenciones en actividad física. El objetivo de este estudio fue conocer el efecto de una intervención educativa sobre el patrón y los conocimientos de actividad física (AF) en niños en edad escolar de 6 -8 años del norte de México. Se empleó un diseño clínico aleatorizado y controlado. Participaron 6 escuelas primarias: 3 escuelas de intervención (n = 80) y 3 de no intervención (n = 79). Se evaluó su antropometría (peso, talla e IMC/edad) y se registró el tipo y frecuencia semanal de la práctica de AF, antes y después de la intervención. Los grupos no mostraron diferencias antropométricas al inicio del programa. Los niños asignados a la intervención no solo mejoraron su conocimiento sobre AF recreativa (p = 0.03), sino que también incrementaron la práctica de caminar (+23%), bailar (+19%) y jugar futbol (+19%) (p ≤ 0.05). El programa educativo tuvo un efecto positivo sobre la participación y el conocimiento de las actividades recreativas de los niños. ABSTRACTThe childhood obesity epidemic has motivated the implementation of physical activity (PA) intervention programs. The aim of this study was to determine the effect of an educational intervention program on the pattern and knowledge of physical activity in 6 -8 year old school children in northern Mexico. A randomly controlled clinical design was employed, involving 6 elementary schools: 3 schools running the intervention program (n = 80) and 3 controls (n = 79). Anthropometry (weight, height and BMI/age) was evaluated, and the type and frequency of weekly practice of PA was recorded before and after the intervention. Anthropometric measurements were similar among all the groups at the beginning of the program. Children assigned to the intervention not only improved their knowledge about recreational PA (p = 0.03) but also increased their practice of walking (+23%), dancing (+19%), and playing soccer (+19%), (p ≤ 0.05). The educational program had a positive effect on participation and knowledge of the recreational activities of children.

“…Previous research provides little evidence of the effectiveness of school-based health education programs on preventing obesity and on the importance of the assessment of their work for supporting broader implementation of successful programs (Veugelers and Fitzgerald 2005;Katz 2009;Inman et al 2011). According to Inman et al (2011:214), "Despite the importance of obesity prevention, there is currently a lack of evidence-based programs available for implementation.…”
