“…After the inclusion of two articles retrieved in manual searches, the descriptive summary consisted of a total of 13 original articles. [18][19][20][21][22][23][24][25][26][27][28][29][30] The study design determined that all included articles had a cross-sectional nature. In all, the summary gathered data from 11 different samples: five from Chile, five from Brazil, and one from Argentina.…”

“…With respect to selection bias, only the evaluation of the articles by Vásquez resulted in a high risk of bias, as their sample was specifically composed of obese children. 28,29 Given the study design, the most common weaknesses were the lack of information about sample representativeness 18,21,[23][24][25][27][28][29] and the use of convenience samples. 23,25 Two articles did not report prior validation of the instrument used to evaluate physical activity 27 and sedentary behavior.…”

Objective: To summarize indicators and describe in detail the methods used to physical activity and sedentary behavior measurement in South American preschool children. Data source: In 2017, we searched for articles on researches carried out in South American countries, which presented physical activity and/or sedentary behavior indicators in children aged two to six years. These searches were conducted in Spanish, English, and Portuguese in four electronic databases (LILACS, PubMed, SciELO, and Web of Science), Google Scholar, and in reference lists. Data summary: Out of 416 articles initially assessed, 13 composed the descriptive summary. Samples from Argentina, Brazil, and Chile were included. Three articles provided accelerometer-based estimates of moderate physical activity: 32, 70.1, and 71.3 minutes per day. The mean total sedentary behavior was 468.3 and 562.9 minutes per day and, considering the cut-off point of 2 hours per day of screen time, we found the following prevalence rates: 39.4, 40.3, and 100%. The studies adopted a wide number of instruments and strategies to evaluate those behaviors. Conclusions: Although the summary has pointed to high exposure to sedentary behavior in preschool children, with particular focus on screen time, it is essential to broaden the discussion and approximate the methods used to assess physical activity and sedentary behavior, making the evidence more comparable and strong, so as to elaborate preventive strategies and actions.

Recibido en octubre 26 de 2014, aceptado en marzo 13 de 2015Citar este artículo así: Díaz XM, Mena CP, Valdivia-Moral P, Rodríguez A, Cachón J. Eficacia de un programa de actividad física y alimentación saludable en escolares chilenos. Hacia promoc. salud. 2015; 20(1): 83-95 DOI: 10.17151/hpsal.2015.20.1.6 Resumen Objetivo: El objetivo de este estudio fue analizar la eficacia de un programa de actividad física y alimentación saludable en escolares chilenos. Materiales y Métodos: Se trabajó con ocho Centros Educativos de Chillán, con un total de 257 niños. La intervención se aplicó durante 5 meses, se desarrollaron talleres durante las reuniones de padres y apoderados con material educativo, a los niños se les incorporaron 45 minutos diarios de AF todos los días de la semana y talleres saludables. Los instrumentos utilizados fueron dos cuestionarios, uno sobre actividad física y el segundo sobre frecuencia alimentaria, además se utilizaron una balanza digital y un tallímetro para obtener estado nutricional. Se midieron peso, talla y se calculó Índice de Masa Corporal (IMC) y el estado nutricional. Resultados: Después de la intervención el porcentaje de la muestra que presentaba exceso de peso disminuyó de 50,2% a 42% en general; en cuanto a las niñas, estas presentaban un 47% de exceso de peso, finalizada la intervención el porcentaje de niñas con exceso de peso disminuyó hasta un 35,9%, quedando en 64,1% los casos en estado normal; en cuanto a la calidad alimentaria, los resultados postintervención muestran que la baja calidad alimentaria disminuyó de un 28% a 5,4%, los que tenían media pasaron de 10,9% a 17,9%, de la misma forma la calidad alta aumentó de un 61,1% a 76,7%. Conclusiones: Los resultados muestran que programas para reducir la obesidad infantil, que son abordados con actividad física y talleres de alimentación saludable, logran resultados positivos.

A Systematic Literature Review with Meta-Analyses of Within- and Between-Day Differences in Objectively Measured Physical Activity in School-Aged Children

et al. 2014

BackgroundTargeting specific time periods of the day or week may enhance physical activity (PA) interventions in youth. The most prudent time segments to target are currently unclear.ObjectivesTo systematically review the literature describing differences in young people’s objectively measured PA on weekdays vs. weekends, in school vs. out of school, weekends vs. out of school and lesson time vs. break time.MethodsElectronic databases were searched for English-language, cross-sectional studies of school-aged children (4–18 years) reporting time-segment-specific accelerometer-measured PA from 01/1990 to 01/2013. We meta-analysed standardised mean differences (SMD) between time segments for mean accelerometer counts per minute (TPA) and minutes in moderate-to-vigorous PA (MVPA). SMD is reported in units of standard deviation; 0.2, 0.5 and 0.8 represent small, moderate and large effects. Heterogeneity was explored using meta-regression (potential effect modifiers: age, sex and study setting).ResultsOf the 54 included studies, 37 were eligible for meta-analyses. Children were more active on weekdays than weekends [pooled SMD (95 % CI) TPA 0.14 (0.08; 0.20), MVPA 0.42 (0.35; 0.49)]. On school days, TPA was lower in school than out of school; however, marginally more MVPA was accumulated in school [TPA −0.24 (−0.40; −0.08), MVPA 0.17 (−0.03; 0.38)]. TPA was slightly lower on weekends than out of school on school days, but a greater absolute volume of MVPA was performed on weekends [TPA −0.10 (−0.19; −0.01), MVPA 1.02 (0.82; 1.23)]. Heterogeneity between studies was high (I2 73.3–96.3 %), with 20.3–53.1 % of variance between studies attributable to potential moderating factors.ConclusionsSchool-aged children are more active on weekdays than weekend days. The outcome measure influences the conclusions for other comparisons. Findings support the tailoring of intervention strategies to specific time periods.Electronic supplementary materialThe online version of this article (doi:10.1007/s40279-014-0215-5) contains supplementary material, which is available to authorized users.
