Childhood obesity and related health consequences continue to be major clinical and public health issues in the United States. Schools provide an opportunity to implement obesity prevention strategies to large and diverse pediatric audiences. Healthier Options for Public Schoolchildren was a quasiexperimental elementary school-based obesity prevention intervention targeting ethnically diverse 6- to 13-year-olds (kindergarten through sixth grade). Over 2 school years (August 2004 to June 2006), five elementary schools (four intervention, one control, N=2,494, 48% Hispanic) in Osceola County, FL, participated in the study. Intervention components included integrated and replicable nutrition, physical activity, and lifestyle educational curricula matched to state curricula standards; modified school meals, including nutrient-dense items, created by registered dietitians; and parent and staff educational components. Demographic, anthropometric, and blood pressure data were collected at baseline and at three time points over 2 years. Repeated measures analysis showed significantly decreased diastolic blood pressure in girls in the intervention group compared to controls (P<0.05). Systolic blood pressure decreased significantly for girls in the intervention group compared to controls during Year 1 (fall 2004 to fall 2005) (P<0.05); while not statistically significant the second year, the trend continued through Year 2. Overall weight z scores and body mass index z scores decreased significantly for girls in the intervention group compared to controls (P<0.05 and P<0.01, respectively). School-based prevention interventions, including nutrition and physical activity components, show promise in improving health, particularly among girls. If healthy weight and blood pressure can be maintained from an early age, cardiovascular disease in early adulthood may be prevented.

Many negative health outcomes are associated with overweight; thus, there is a need for effective weight-loss interventions tailored to this group. This study evaluated 24-month outcomes of a randomized, controlled trial involving an intensive lifestyle-based weight maintenance program targeting overweight Mexican-American children at a charter school in Houston, Texas. A total of 60 children (33 males, 55%) between the ages of 10 and 14 at or >85th percentile for BMI were recruited. Participants were randomized to an instructor-led intervention (ILI) or a self-help (SH) program, both aimed at modifying eating and physical activity behaviors using behavior modification strategies. Changes in participants' standardized BMI (<i>z</i>BMI) were assessed at baseline, 1, and 2 years. Tricep skinfold, total cholesterol, triglycerides, high-density lipoprotein cholesterol, and calculated low-density lipoprotein were assessed at baseline and 1 year. ILI participants showed significantly greater decreases in <i>z</i>BMI at 1 and 2 years (<i>F</i> = 26.8, <i>P</i> < 0.001, <i>F</i> = 4.1, <i>P</i> < 0.05, respectively) compared to SH controls. ILI participants showed greater improvements in body composition, as measured by tricep skinfold (<i>F</i> = 9.75, <i>P</i> < 0.01). Children in the ILI condition experienced benefits with respect to total cholesterol (<i>F</i> = 7.19, <i>P</i> < 0.05) and triglycerides (<i>F</i> = 4.35, <i>P</i> < 0.05) compared to children in the SH condition. Overall, the school-based intervention resulted in improved weight and clinical outcomes in overweight Mexican-American children, and <i>z</i>BMI was maintained over 2 years.

INTRODUCTION: Successfully addressing childhood onset obesity requires multilevel (individual, community, and governmental), multi-agency collaboration.
METHODS: The Healthier Options for Public Schoolchildren (HOPS)/OrganWise Guys (OWG) quasi-experimental controlled pilot study (four intervention schools, one control school, total N=3,769; 50.2% Hispanic) was an elementary school-based obesity prevention intervention designed to keep children at a normal, healthy weight, and improve health status and academic achievement. The HOPS/OWG included the following replicable, holistic components: (1) modified dietary offerings, (2) nutrition/lifestyle educational curricula; (3) physical activity component; and (4) wellness projects. Demographic, anthropometric (body mass index [BMI]), blood pressure, and academic data were collected during the two-year study period (2004-6).
RESULTS: Statistically significant improvements in BMI, blood pressure, and academic scores, among low-income Hispanic and White children in particular, were seen in the intervention versus controls.
CONCLUSION: Holistic school-based obesity prevention interventions can improve health outcomes and academic performance, in particular among high-risk populations.
OBJECTIVE: The objective was to evaluate quality of life (QOL) in at-risk-for-overweight and overweight Mexican-American children after participating in 6 months of intensive weight management or self-help.
RESEARCH METHODS AND PROCEDURES: Eighty sixth- and seventh-grade at-risk-for-overweight (BMI >or=85th to <95th percentile) and overweight (BMI >or=95th percentile) Mexican-American children were randomly assigned to either intensive instructor-led intervention (ILI) or self-help (SH). The ILI condition included daily participation for 12 weeks in a school-based program comprised of nutrition education, physical activity, and behavior modification, followed by ongoing monthly maintenance. QOL was assessed at baseline and 6 months via child self-report PedsQL. QOL outcomes were compared across treatment groups, and the impact of change in zBMI on change in QOL was evaluated.
RESULTS: Children in the ILI condition not only achieved significantly greater weight loss (zBMI, -0.13 +/- 0.14; p < 0.001) but also significantly greater physical QOL improvements than those in the SH condition at 6 months (p < 0.05). Furthermore, physical QOL increases were associated with zBMI reduction (p < 0.05). However, neither psychosocial nor total QOL was significantly impacted by intervention or zBMI change.
DISCUSSION: These findings show that even modest decreases in zBMI after weight management result in improved physical QOL in Mexican-American children. These results illustrate the clear need to include evaluation of QOL in the process of identifying effective weight management programs.
Childhood overweight has increased significantly in the past 20 years, with the highest rates noted among Mexican Americans. Schools are an optimal setting for intervention efforts; however, few programs have demonstrated actual decreases in weight. This study evaluated an intensive school-based program designed to result in weight reduction for overweight Mexican American children. A total of 71 children (32 males, 48%) between the ages of 10 and 14 at or above the 85th percentile for body mass index (BMI) were randomized into a six-month intensive intervention (II) or self-help (SH) condition. Results revealed that children in the II condition significantly reduced their standardized BMI (zBMI) when compared with the children in the self-help condition (F(2,62)=6.58, p=0.003). The change in zBMI was significantly different at both 3 and 6 months (F(1,63)=5.74, p=0.019, F(1,63)=12.61, p=0.001, respectively) with II participants showing greater decreases in weight. The 3-month change in zBMI for the II participants was a decrease of 0.07 compared with a decrease of 0.01 for SH participants. The 6-month change in zBMI was a decrease of 0.11 for II and an increase of 0.03 for SH. Overall, the results are promising, suggesting that an intensive school-based intervention may be an effective means for promoting weight loss in overweight Mexican American children.
OBJECTIVE: Hip-Hop to Health Jr. was a diet/physical activity intervention designed to reduce gains in BMI (kilograms per meter squared) in preschool minority children. Research Methods and Procedures: Twelve predominantly Latino Head Start centers participated in a group-randomized trial conducted between Fall 2001 and Winter 2003. Six centers were randomized to a culturally proficient 14-week (three times weekly) diet/physical activity intervention. Parents participated by completing weekly homework assignments. The children in the other six centers received a general health intervention that did not address either diet or physical activity. The primary outcome was change in BMI, and secondary outcomes were changes in dietary intake and physical activity. Measures were collected at baseline, post-intervention, and at Years 1 and 2 follow-up. RESULTS: There were no significant differences between intervention and control schools in either primary or secondary outcomes at post-intervention, Year 1, or Year 2 follow-ups. DISCUSSION: When Hip-Hop to Health Jr. was conducted in predominantly black Head Start centers, it was effective in reducing subsequent increases in BMI in preschool children. In contrast, when the program was conducted in Latino centers, it was not effective. Although the intervention did not prevent excessive weight gain in Latino children, it was very well received. Future interventions with this population may require further cultural tailoring and a more robust parent intervention. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
OBJECTIVE: To assess the impact on children's health of translating an evidence-based national intervention trial (Child and Adolescent Trial for Cardiovascular Health [CATCH]) to low-income elementary schools with primarily Hispanic students.
DESIGN: An untreated, matched control group design with repeated dependent pretest and posttest samples was used.
SETTING: Four El Paso CATCH and 4 control elementary schools in El Paso, Tex, along the US-Mexico border region. All had Title I status (most were low-income students).
PARTICIPANTS: Participants were 896 third-grade children (473 control schools [224 girls and 249 boys] and 423 CATCH schools [199 girls and 224 boys]); 93% were Hispanic.
INTERVENTION: Community-based implementation of the national CATCH program.
MAIN OUTCOME MEASURES: Risk of overweight or overweight, body mass index, waist-to-hip ratio, yards run in 9 minutes, passing rates for Fitnessgram national mile standards, moderate to vigorous physical activity and vigorous physical activity in physical education class, and percentage of fat and sodium in school lunches.
RESULTS: Girls in control schools had significant increases in percentage of risk of overweight or overweight from third (26%) to fifth (39%) grades, as did girls in CATCH schools (30%-32%); however, the rate of increase for girls in the CATCH schools was significantly lower (2%) compared with the rate for control girls (13%). A similar pattern was seen for boys, with a rate of increase for boys in CATCH schools of 1% (40%-41%), which was significantly less than the 9% increase (40% to 49%) for control boys.
CONCLUSIONS: The translation of the national CATCH program to low-income schools with Hispanic students successfully slowed the epidemic increase in risk of overweight or overweight seen in control school children. An emphasis should be placed on community organizing and evaluation feedback when implementing evidence-based school health programs in low-income Hispanic communities.
Community-based interventions are needed to reduce the burden of childhood obesity.
PURPOSE:
To evaluate the impact of a multi-level promotora-based (Community Health Advisor) intervention to promote healthy eating and physical activity and prevent excess weight gain among Latino children.
METHODS:
Thirteen elementary schools were randomized to one of four intervention conditions: individual/family level (Family-only), school/community level (Community-only), combined (Family + Community), or a measurement-only condition. Participants were 808 Latino parents and their children enrolled in kindergarten through 2(nd) grade. Measures included parent and child body mass index (BMI) and a self-administered parent survey that assessed several parent and child behaviors.
RESULTS:
There were no significant intervention effects on children's BMI z-score. The family intervention changed several obesity-related child behaviors (e.g., fruit/vegetable consumption) and these were mediated by changes in parenting variables (e.g., parent monitoring).
CONCLUSION:
A promotora-based behavioral intervention was efficacious at changing parental factors and child obesity-related health behaviors.
