Outcomes of a school-based intervention (RESCATE) to improve physical activity patterns in Mexican children aged 8-10 years

Abstract

The aim of this study was to evaluate the impact of an intervention program on the patterns of physical activity in 8- to 10-year-old Mexican children from lower socioeconomic status. This study performed a randomized controlled field trial in 498 children aged 8-10 years from 10 public schools of low socioeconomic status in Mexico City. Schools were randomly assigned to intervention (n = 5) or control (n = 5) groups and followed up during 12 months. Physical and sedentary activities were assessed at the beginning of the program and after 6 and 12 months. At the end of follow-up, there was a significant increase in the performance of moderate physical activity (MPA) among children in intervention group who had not performed MPA at baseline any day of the week (40%, P = 0.04) but not in the control group (8%, P = not significant). The intervention group also showed a significant reduction in the proportion of children who spent more than 3 hours a day playing video games (from 23 to 13%, P = 0.01), while control group did not show significant changes. Given these findings, we conclude that intervention was able to modify positively physical activity and reduce time spent on such sedentary activities as video games among those at highest risk studied children.

Effectiveness of preventive school-based obesity interventions in low- and middle-income countries: a systematic review

“…The remaining 2 PA interventions compared programmed PA with a regular physical-education curriculum (55) and provided tailored education according to the different stages of the Health Action Process Approach (61). Most (n = 9) of the combined interventions used diet and PA education as their key strategy (45,46,62,(65)(66)(67)(68)(69)(70)(71)(72), which was accompanied by environmental or organizational changes in the schools in 5 of them (46,62,65,66,(69)(70)(71). The remaining 2 interventions provided lectures and group counseling on cardiovascular disease prevention (44) and trained primary caregivers of children in healthy nutrition and activity (63,64).…”

Programas para la prevención de la obesidad en escolares de 5 a 10 Años: Revisión de la literatura

“…Así, 16 investigaciones utilizaron grupo control (1,3,5-7,13,22-31), 3 investigaciones utilizaron un diseño pre-test y post-test sin grupo control (18,32,33) y 3 trabajos no indicaron el tipo de diseño (2,4,34). Solo un estudio realizó una valoración posterior a la finalización del programa (re-test) (36).…”

“…Un total de 101.193 escolares fueron incluidos en los diversos trabajos analizados (1)(2)(3)(4)(5)(6)(7)10,13,18,19,(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)33,34,36).…”

“…Únicamente dos estudios realizan una valoración psicológica (3,4). En 14 estudios se llevó a cabo una valoración sobre hábitos alimentarios y conocimientos nutricionales, utilizando en la mayoría de los casos cuestionarios para su valoración (2)(3)(4)6,10,15,19,26,(30)(31)(32)35,36).…”

“…En 16 de las 24 intervenciones se evaluó la actividad física, siendo en 6 de ellas a través de acelerometría (1,3,5,6,24,34) y en 10 mediante cuestionarios (2,5,6,23,25,26,30,31,33,36).…”
