Impact of an Elementary School-Based Intervention on Physical Activity Time and Aerobic Capacity, Georgia, 2013-2014.

ABSTRACT: OBJECTIVES:The objectives of this study were to (1) determine the impact of a 1-year elementary school physical activity intervention on changes in teacher-reported school-based physical activity time and (2) assess the relationship between these changes and changes in student aerobic capacity. METHODS:HealthMPowers, a nonprofit organization, provided a multicomponent physical activity intervention to 3479 students in 39 schools in Georgia during 2013-2014. HealthMPowers administered a survey to faculty members before (August 2013) and after (May 2014) the intervention to measure student physical activity times. The organization collected pre- and post-intervention Progressive Aerobic Cardiovascular Endurance Run (PACER) laps (a measure of aerobic capacity that awards 1 lap for each completed 20-meter lap) for 2342 fourth-grade students. We performed linear regression to determine the relationship between school-level changes in teacher-reported school-based physical activity time and student aerobic capacity. RESULTS:The weekly estimated teacher-reported time in physical activity increased by 39 minutes from pre- to post-intervention: 21 minutes for recess, 17 minutes for classroom, and 1 minute for physical education. The mean number of student PACER laps increased by 3 laps from pre- to post-intervention, and 1515 of 2342 (65%) students increased the number of PACER laps completed. We observed a positive association between school-level changes in school-based physical activity time and school-level changes in PACER laps ( r = 0.38; 95% confidence interval, 0.29-0.46). CONCLUSIONS:These findings highlight the need for more prospective research into multicomponent physical activity interventions. Rigorous testing, including randomized controlled trials of large-scale implementations, is needed to examine how these school-based interventions might be used to improve the physical activity and fitness of larger populations of children.

Project description:IntroductionThis study measures effects on the receipt of preventive care among children enrolled in Georgia's Medicaid or Children's Health Insurance Program associated with the implementation of new elementary school-based health centers. The study sites differed by geographic environment and predominant race/ethnicity (rural white, non-Hispanic; black, small city; and suburban Hispanic).MethodsA quasi-experimental treatment/control cohort study used Medicaid/Children's Health Insurance Program claims/enrollment data for children in school years before implementation (2011-2012 and 2012-2013) versus after implementation (2013-2014 to 2016-2017) of school-based health centers to estimate effects on preventive care among children with (treatment) and without (control) access to a school-based health center. Data analysis was performed in 2017-2019. There were 1,531 unique children in the treatment group with an average of 4.18 school years observed and 1,737 in the control group with 4.32 school years observed. A total of 1,243 Medicaid/Children's Health Insurance Program-insured children in the treatment group used their school-based health centers.ResultsSignificant increases in well-child visits (5.9 percentage points, p<0.01) and influenza vaccination (6.9 percentage points, p<0.01) were found for children with versus without a new school-based health center. This represents a 15% increase from the pre-implementation percentage (38.8%) with a well-child visit and a 25% increase in influenza vaccinations. Increases were found only in the 2 school-based health centers with predominantly minority students. The 18.7 percentage point (p<0.01) increase in diet/counseling among obese/overweight Hispanic children represented a doubling from a 15.3% baseline.ConclusionsImplementation of elementary school-based health centers increased the receipt of key preventive care among young, publicly insured children in urban areas of Georgia, with potential reductions in racial and ethnic disparities.

Project description:BackgroundAs internet use becomes more widespread, the screen time (ST) of elementary school students increases yearly. It is known that longer durations of ST can affect obesity, physical activity, dry eye disease, and learning ability. However, the effects of ST just before bedtime have not been clarified. Therefore, we examined ST duration and timing effects on elementary school children.MethodsWe conducted a survey of 7419 elementary school students in Tokyo, Japan using a questionnaire on food education. ST duration and timing (just before bedtime) served as the explanatory variables, and the relationship between obesity, physical activity, dry eyes, and learning ability was analyzed using logistic regression analysis. Gender, school year, height, and weight were considered confounding factors. First, we examined whether ST duration and timing were related to each objective variable, using a univariate model to examine all variables. Thereafter, we performed multivariate logistic regression analyses for all variables showing a significant difference in the univariate models.ResultsA significant association was observed between ST duration and obesity, physical activity, and academic performance, indicating that a longer ST duration may lead to obesity, decreased physical activity, and decreased academic performance. ST timing was associated with obesity, dry eyes, and academic performance, and ST immediately before bedtime contributed to obesity, dry eyes, and reduced academic performance. Furthermore, the results of investigating the combined effect of ST duration and timing (immediately before bedtime) on these factors revealed that ST timing has a greater effect on dry eyes, and ST duration has a greater effect on academic performance.ConclusionOur findings indicate that ST in school children is related to obesity, physical activity, dry eyes, and learning ability, and they suggest that not only the duration but also the timing of ST is important.
