Abstract
Childhood obesity is a major public health concern. However, predictors of successful outcomes for patients treated at multidisciplinary community hospital-based pediatric weight management programs remain poorly understood. We conducted a retrospective analysis to evaluate 633 pediatric patients from ages 2 to 18 at a tertiary pediatric weight management program in 2018. Predictors were evaluated in univariate comparisons, and significant variables were included in a linear regression analysis to identify factors associated with improvements in body mass index relative to the age- and sex-specific 95th percentile body mass index (%BMIp95). We found that male sex and increased number of clinical visits were independently and significantly associated with reductions in %BMIp95. Baseline %BMIp95, age, preferred language, and insurance status were not significant predictors of outcomes. A total of 398 (63%) patients experienced a decrease in %BMIp95 from baseline to follow-up. One quarter (24.8%) of patients experienced a decrease in %BMIp95 of at least 5%, a threshold associated with cardiometabolic improvements. Further, we observed significant improvements in cholesterol, triglycerides, alanine aminotransferase, aspartate aminotransferase, HbA1c, and waist circumference. These findings support a potential need for sex- and gender-tailored care as well as the benefits of increased access to pediatric weight management programs.

Abstract
Background: South Asian children have a higher prevalence of cardiovascular disease risk factors compared with children of other ethnic backgrounds. Our objective was to explore the feasibility, acceptability, and potential fitness-related impact of a 7-month afterschool Bhangra dance intervention for South Asian children. Methods: We recruited 172 children grades 3 through 6 across 4 elementary schools for an intervention involving twice weekly Bhangra sessions in the school setting. Feasibility and acceptability were defined by recruitment, attendance, and retention metrics. The primary fitness outcome was cardiorespiratory fitness (CRF), measured via shuttle run laps and VO2 max. Secondary fitness outcomes included musculoskeletal (vertical jump height) and morphological fitness (waist circumference and BMI). Results: Sample size ranged from 28 to 54 participants per school (n = 172); mean attendance rate was 74%; and retention rate was 87%. VO2 max and shuttle laps increased by 1.4 mL·kg/min [95% confidence interval (CI): 0.93 to 1.84] and by 7.6 (95% CI: 6.11 to 9.08), respectively. Both these improvements remained significant after controlling for sex and age (VO2 max) and sex and baseline weight (shuttle laps). Musculoskeletal and morphological fitness indices also improved. Conclusions: Findings suggest that an afterschool Bhangra dance intervention is feasible, acceptable, and associated with CRF improvements as well as other indices of physical fitness.

Identification and evaluation of risk of generalizability biases in pilot versus efficacy/effectiveness trials: a systematic review and meta-analysis. Int J Behav Nutr Phys Act 2020; 17:19. [PMID: 32046735 PMCID: PMC7014944 DOI: 10.1186/s12966-020-0918-y] [Citation(s) in RCA: 62] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Accepted: 01/23/2020] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Preliminary evaluations of behavioral interventions, referred to as pilot studies, predate the conduct of many large-scale efficacy/effectiveness trial. The ability of a pilot study to inform an efficacy/effectiveness trial relies on careful considerations in the design, delivery, and interpretation of the pilot results to avoid exaggerated early discoveries that may lead to subsequent failed efficacy/effectiveness trials. "Risk of generalizability biases (RGB)" in pilot studies may reduce the probability of replicating results in a larger efficacy/effectiveness trial. We aimed to generate an operational list of potential RGBs and to evaluate their impact in pairs of published pilot studies and larger, more well-powered trial on the topic of childhood obesity. METHODS We conducted a systematic literature review to identify published pilot studies that had a published larger-scale trial of the same or similar intervention. Searches were updated and completed through December 31st, 2018. Eligible studies were behavioral interventions involving youth (≤18 yrs) on a topic related to childhood obesity (e.g., prevention/treatment, weight reduction, physical activity, diet, sleep, screen time/sedentary behavior). Extracted information included study characteristics and all outcomes. A list of 9 RGBs were defined and coded: intervention intensity bias, implementation support bias, delivery agent bias, target audience bias, duration bias, setting bias, measurement bias, directional conclusion bias, and outcome bias. Three reviewers independently coded for the presence of RGBs. Multi-level random effects meta-analyses were performed to investigate the association of the biases to study outcomes. RESULTS A total of 39 pilot and larger trial pairs were identified. The frequency of the biases varied: delivery agent bias (19/39 pairs), duration bias (15/39), implementation support bias (13/39), outcome bias (6/39), measurement bias (4/39), directional conclusion bias (3/39), target audience bias (3/39), intervention intensity bias (1/39), and setting bias (0/39). In meta-analyses, delivery agent, implementation support, duration, and measurement bias were associated with an attenuation of the effect size of - 0.325 (95CI - 0.556 to - 0.094), - 0.346 (- 0.640 to - 0.052), - 0.342 (- 0.498 to - 0.187), and - 0.360 (- 0.631 to - 0.089), respectively. CONCLUSIONS Pre-emptive avoidance of RGBs during the initial testing of an intervention may diminish the voltage drop between pilot and larger efficacy/effectiveness trials and enhance the odds of successful translation.

Abstract
In Canada, South Asian (SA) children are more likely to be overweight and physically inactive than non-SAs. This study uses a mixed-methods embedded design to investigate factors associated with physical activity (PA) among SAs, and develops a culturally-relevant exercise intervention for SA children ages 8-11. Twenty-eight (28) participants including children, parents, principals, teachers, and Bhangra instructors across four elementary schools in Surrey, BC participated in semi-structured interviews and a self-report survey. Using the immersion/crystallization approach, four major themes were identified: (1) awareness of the importance and benefits of PA, (2) discrepancy between expectations and actual opportunities for PA in the school-setting, (3) sub-optimal conditions for PA at school and home, and (4) intervention characteristics conducive for promoting exercise in SA children. Competing demands and lack of opportunities posed as prominent obstacles. To address these barriers, a culturally-appealing exercise intervention may offer a viable approach to motivate SA children to exercise.

Abstract
Ethnic minority children living in high poverty neighborhoods are at high risk of having insufficient physical activity (PA) during school days and, thus, the importance of school as a place to facilitate PA in these underserved children has been largely emphasized. This study examined the levels and patterns of PA in minority children, with particular focus on the relative contributions of regular physical education (PE) and school-based afterschool PA program in promoting moderate- and vigorous-intensity PA (MVPA) during school days. PA data were repeatedly measured using a Polar Active accelerometer across multiple school days (M = 5.3 days per child), from seventy-five ethnic minority children attending a Title I public elementary school in a high-poverty neighborhood in the US. The minutes and percentage of MVPA accumulated during school, PE, and afterschool PA program were compared to the current recommendations (≥30-min of MVPA during school hours; and ≥50% of MVPA during PE or afterschool PA program) as well as by the demographic characteristics including sex, grade, ethnicity, and weight status using a general linear mixed model that accounts for repeated observations. On average, children spent 41.6 mins (SE = 1.8) of MVPA during school hours and of those, 14.1 mins (SE = 0.6) were contributed during PE. The average proportion of time spent in MVPA during PE was 31.3% (SE = 1.3), which was significantly lower than the recommendation (≥50% of MVPA), whereas 54.2% (SE = 1.2) of time in afterschool PA program were spent in MVPA. The percentage of monitoring days meeting current recommendations were 69.5% (SE = 0.03), 20.8% (SE = 0.02), and 59.6% (SE = 0.03) for during school, PE, and afterschool PA program, respectively. Our findings highlighted that school-based afterschool PA, in addition to regular PE classes, could be of great benefit to promote PA in minority children during school days. Further research and practice are still needed to increase MVPA during school hours, particularly during PE classes.

Abstract
Participation in recommended levels of physical activity promotes a healthy body weight and reduced chronic disease risk. To inform investment in prevention initiatives, we simulate the national implementation, impact on physical activity and childhood obesity and associated cost-effectiveness (versus the status quo) of six recommended strategies that can be applied throughout childhood to increase physical activity in US school, afterschool and childcare settings. In 2016, the Childhood Obesity Intervention Cost Effectiveness Study (CHOICES) systematic review process identified six interventions for study. A microsimulation model estimated intervention outcomes 2015-2025 including changes in mean MET-hours/day, intervention reach and cost per person, cost per MET-hour change, ten-year net costs to society and cases of childhood obesity prevented. First year reach of the interventions ranged from 90,000 youth attending a Healthy Afterschool Program to 31.3 million youth reached by Active School Day policies. Mean MET-hour/day/person increases ranged from 0.05 MET-hour/day/person for Active PE and Healthy Afterschool to 1.29 MET-hour/day/person for the implementation of New Afterschool Programs. Cost per MET-hour change ranged from cost saving to $3.14. Approximately 2500 to 110,000 cases of children with obesity could be prevented depending on the intervention implemented. All of the six interventions are estimated to increase physical activity levels among children and adolescents in the US population and prevent cases of childhood obesity. Results do not include other impacts of increased physical activity, including cognitive and behavioral effects. Decision-makers can use these methods to inform prioritization of physical activity promotion and obesity prevention on policy agendas.

Abstract
After-school programs are an ideal setting for childhood obesity prevention interventions. This qualitative study examined the implementation of a training technique in the Children’s Healthy Eating and Exercise Program: motivational interviewing. Participants included 19 children in Grades 3 through 5, nine coaches enrolled in university health education classes, and four parents. Nine lessons were presented during the fall session (N = 5) and eight during the spring (N = 14), with five individual coaching sessions per child. From September, 2014 through April 2015, child and coach perceptions were assessed using goal sheets, surveys, a focus group, and the analysis of the video recording of a health habit commercial created by teams of children grouped by gender. Children developed weekly eating and exercise goals with coaches and reported on their progress the following week. Following the intervention, children reported improved eating and exercise habits and coaches reported they learned more about healthy food options for themselves. Overall, children responded positively to the motivational interviewing. Involving teachers may allow for dissemination of lessons and reinforcement for healthy choices during the school day. Involving parents in training may remove roadblocks to healthy lifestyle changes for children for nonschool hours and when packing lunches.

Abstract
Previous reviews of childhood obesity prevention have focused largely on schools and findings have been inconsistent. Funded by the US Agency for Healthcare Research and Quality (AHRQ) and the National Institutes of Health, we systematically evaluated the effectiveness of childhood obesity prevention programmes conducted in high-income countries and implemented in various settings. We searched MEDLINE®, Embase, PsycINFO, CINAHL®, ClinicalTrials.gov and the Cochrane Library from inception through 22 April 2013 for relevant studies, including randomized controlled trials, quasi-experimental studies and natural experiments, targeting diet, physical activity or both, and conducted in children aged 2-18 in high-income countries. Two reviewers independently abstracted the data. The strength of evidence (SOE) supporting interventions was graded for each study setting (e.g. home, school). Meta-analyses were performed on studies judged sufficiently similar and appropriate to pool using random effect models. This paper reported our findings on various adiposity-related outcomes. We identified 147 articles (139 intervention studies) of which 115 studies were primarily school based, although other settings could have been involved. Most were conducted in the United States and within the past decade. SOE was high for physical activity-only interventions delivered in schools with home involvement or combined diet-physical activity interventions delivered in schools with both home and community components. SOE was moderate for school-based interventions targeting either diet or physical activity, combined interventions delivered in schools with home or community components or combined interventions delivered in the community with a school component. SOE was low for combined interventions in childcare or home settings. Evidence was insufficient for other interventions. In conclusion, at least moderately strong evidence supports the effectiveness of school-based interventions for preventing childhood obesity. More research is needed to evaluate programmes in other settings or of other design types, especially environmental, policy and consumer health informatics-oriented interventions.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:566-94. [PMID: 25584423 PMCID: PMC4306880 DOI: 10.3390/ijerph120100566] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/26/2014] [Accepted: 12/18/2014] [Indexed: 11/18/2022]
Abstract
Background and Aims: The metabolic risks associated with obesity are greater for South Asian populations compared with White or other ethnic groups, and levels of obesity in childhood are known to track into adulthood. Tackling obesity in South Asians is therefore a high priority. The rationale for this systematic review is the suggestion that there may be differential effectiveness in diet and physical activity interventions in South Asian populations compared with other ethnicities. The research territory of the present review is an emergent, rather than mature, field of enquiry, but is urgently needed. Thus the aim of this systematic review and meta-analysis was to assess the effectiveness of diet and physical activity interventions to prevent or treat obesity in South Asians living in or outside of South Asia and to describe the characteristics of effective interventions. Methods: Systematic review of any type of lifestyle intervention, of any length of follow-up that reported any anthropometric measure for children or adults of South Asian ethnicity. There was no restriction on the type of comparator; randomised controlled trials, controlled clinical trials, and before-after studies were included. A comprehensive search strategy was implemented in five electronic databases: ASSIA, Cochrane Controlled Trials Register, Embase, Medline and Social Sciences Citation Index. The search was limited to English language abstracts published between January 2006 and January 2014. References were screened; data extraction and quality assessment were carried out by two reviewers. Results are presented in narrative synthesis and meta-analysis. Results: Twenty-nine studies were included, seven children, 21 adult and one mixed age. No studies in children under six were identified. Sixteen studies were conducted in South Asia, ten in Europe and three in USA. Effective or promising trials include physical activity interventions in South Asian men in Norway and South Asian school-children in the UK. A home-based, family-orientated diet and physical activity intervention improved obesity outcomes in South Asian adults in the UK, when adjusted for baseline differences. Meta-analyses of interventions in children showed no significant difference between intervention and control for body mass index or waist circumference. Meta-analyses of adult interventions showed significant improvement in weight in data from two trials adjusted for baseline differences (mean difference −1.82 kgs, 95% confidence interval −2.48 to −1.16) and in unadjusted data from three trials following sensitivity analysis (mean difference −1.20 kgs, 95% confidence interval −2.23 to −0.17). Meta-analyses showed no significant differences in body mass index and waist circumference for adults. Twenty of 24 intervention groups showed improvements in adult body mass index from baseline to follow-up; average change in high quality studies (n = 7) ranged from 0.31 to −0.8 kg/m2. There was no evidence that interventions were more or less effective according to whether the intervention was set in South Asia or not, or by socio-economic status. Conclusions: Meta-analysis of a limited number of controlled trials found an unclear picture of the effects of interventions on body mass index for South Asian children. Meta-analyses of a limited number of controlled trials showed significant improvement in weight for adults but no significant differences in body mass index and waist circumference. One high quality study in South Asian children found that a school-based physical activity intervention that was delivered within the normal school day which was culturally sensitive, was effective. There is also evidence of culturally appropriate approaches to, and characteristics of, effective interventions in adults which we believe could be transferred and used to develop effective interventions in children.

Reducing childhood obesity through U.S. federal policy: a microsimulation analysis. Am J Prev Med 2014; 47:604-12. [PMID: 25175764 PMCID: PMC4762259 DOI: 10.1016/j.amepre.2014.07.011] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2013] [Revised: 06/20/2014] [Accepted: 07/17/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Childhood obesity prevalence remains high in the U.S., especially among racial/ethnic minorities and low-income populations. Federal policy is important in improving public health given its broad reach. Information is needed about federal policies that could reduce childhood obesity rates and by how much. PURPOSE To estimate the impact of three federal policies on childhood obesity prevalence in 2032, after 20 years of implementation. METHODS Criteria were used to select the three following policies to reduce childhood obesity from 26 recommended policies: afterschool physical activity programs, a $0.01/ounce sugar-sweetened beverage (SSB) excise tax, and a ban on child-directed fast food TV advertising. For each policy, the literature was reviewed from January 2000 through July 2012 to find evidence of effectiveness and create average effect sizes. In 2012, a Markov microsimulation model estimated each policy's impact on diet or physical activity, and then BMI, in a simulated school-aged population in 2032. RESULTS The microsimulation predicted that afterschool physical activity programs would reduce obesity the most among children aged 6-12 years (1.8 percentage points) and the advertising ban would reduce obesity the least (0.9 percentage points). The SSB excise tax would reduce obesity the most among adolescents aged 13-18 years (2.4 percentage points). All three policies would reduce obesity more among blacks and Hispanics than whites, with the SSB excise tax reducing obesity disparities the most. CONCLUSIONS All three policies would reduce childhood obesity prevalence by 2032. However, a national $0.01/ounce SSB excise tax is the best option.

Abstract
Outside-of-school time (OST; i.e. before/after-school hours, summer time), theory-based interventions are potential strategies for addressing increased obesity among African American youth. This review assessed interventions across multiple settings that took place during OST among African American youth aged 5-18 years old. Seven databases were searched for studies published prior to October 2013; 28 prevention and treatment interventions that assessed weight or related behaviours as a primary or secondary outcome were identified. Overall, these studies reported heterogeneous intervention length, theoretical frameworks, methodological quality, outcomes, cultural adaption and community engagement; the latter two attributes have been identified as potentially important intervention strategies when working with African Americans. Although not always significant, generally, outcomes were in the desired direction. When examining programmes by time of intervention (i.e. after-school, summer time, time not specified or multiple time periods), much of the variability remained, but some similarities emerged. After-school studies generally had a positive impact on physical activity, fruit/vegetable consumption and caloric intake, or body composition. The single summer time intervention showed a trend towards reduced body mass index. Overall findings suggest that after-school and summer programmes, alone or perhaps in combination, offer potential benefits for African American youth and could favourably influence diet and physical activity behaviour.

Abstract
BACKGROUND Children with disabilities are more likely to be overweight or obese and less likely to engage in physical activities versus their peers without disabilities. OBJECTIVE The effect of a structured afterschool program housed in a large county parks system on several obesity-related health outcomes among children with disabilities was examined. METHODS Children/adolescents with a developmental and/or intellectual disability ages 6-22 (N = 52, mean age 13.7 years) who participated in an afterschool (either 2010-2011 or 2011-2012 school year) health and wellness program called Fit-2-Play™ were assessed. Pre-post comparison of outcome variables (mean height, weight, waist/hip/midarm circumference, fitness tests, and a 9-item health and wellness knowledge assessment) via general linear mixed models analysis was conducted to evaluate the effectiveness of the program for normal and overweight/obese participants. RESULTS Normal weight participants significantly improved pre-post mean number of push-ups (9.69-14.23, p = 0.01) and laps on the PACER test (8.54-11.38, p < 0.01) and the overweight/obese group significantly improved the number of sit ups (7.51-9.84, p < 0.01) and push ups (4.77-9.89, p < 0.001). Pre-post mean health and wellness knowledge composite scores significantly improved for all participants (p < 0.01). CONCLUSIONS Parks-based afterschool programs can be effective community resources for instilling physical health in both normal weight and overweight/obese children with disabilities. More studies are needed to ascertain whether community-based afterschool health and wellness programs can be implemented and sustained across this population.

Abstract
PURPOSE The objective of this study was to examine the effect of a structured after-school program housed in a large county parks system on participant health and wellness outcomes. DESIGN Longitudinal cohort study over one school year (fall 2011-spring 2012). SETTING A total of 23 county parks in Florida. SUBJECTS Children ages 5 to 16 (N = 349, 55% non-Hispanic black, 40% Hispanic, mean age 8.9 years). INTERVENTION An after-school program called Fit-2-Play that integrates daily standardized physical activity and health and wellness education components. MEASURES Preintervention (August/September 2011) and postintervention (May/June 2012) anthropometric, systolic/diastolic blood pressure, fitness, and health and wellness knowledge measurements were collected. ANALYSIS Comparison of pre-post outcome measure means were assessed via general linear mixed models for normal-weight (body mass index [BMI] <85th percentile for age and sex) and overweight/obese (BMI ≥85th percentile for age and sex) participants. RESULTS The overweight/obese group significantly decreased their mean (1) BMI z score (2.0 to 1.8, p < .01) and (2) subscapular skinfold measurements (19.4 to 17.5 mm, p < .01) and increased (1) mean laps on the Progressive Aerobic Cardiovascular Endurance Run test (10.8 to 12.5, p = .04) and (2) percentage with normal systolic blood pressure (58.1% to 71.0%, p = .03) from pretest to posttest. On average, participants significantly improved their health and wellness knowledge over the school year (p < .01). Normal-weight participants maintained healthy BMI ranges and significantly increased fitness levels. CONCLUSION Findings suggest that the Fit-2-Play after-school programs can be a significant resource for combating childhood obesity and instilling positive physical health in children, particularly among ethnic and socioeconomically diverse communities.

Abstract
In the past 20 years, the prevalence of obesity in the United States increased almost 50% among adults and by 300% in children. Today, 9.7% of all U.S. infants up to 2 years old have abnormally high weight-for-recumbent length; 25% of children under age 5 are either overweight or obese; and 17% of adolescents are obese. Ethnic disparities in the rates of obesity are also large and apparent in childhood. Further, 44% of obese adolescents have metabolic syndrome. Obese children tend to become obese adults; thus, in a decade, young adults will likely have much higher risks of chronic disease, which has tremendous implications for the healthcare system. However, early childhood may be the best time to prevent obesity. Teachers' healthy eating choices are positively associated with changes in body mass index percentiles for children, for example. In addition, 8 million children attend afterschool programs, which can successfully promote health and wellness and successfully treat obesity. This childhood epidemic of obesity and its health-related consequences in adolescents should be a clinical and public health priority. However, this major public health problem cannot be managed solely in clinical settings. Rather, public health strategies must be integrated into home and family, school and community-based settings.

Abstract
IMPORTANCE Identifying community-based programs that increase physical activity among diverse youth could yield sustainable tools to reduce obesity and obesity disparities. OBJECTIVE To evaluate the impact of a community-based after-school soccer and youth development program, America SCORES, on students' physical activity, weight status, and fitness. DESIGN Cluster-randomized trial. Study measures were collected in the fall (baseline), winter (midpoint), and spring (end point) of the 2009-2010 school year. SETTING After-school programs in 6 schools within a large urban school district. PARTICIPANTS All 4th and 5th grade students in after-school programs at the study schools were eligible. INTERVENTION Three schools were randomized to receive the SCORES after-school program, delivered via the train-the-trainer model. MAIN OUTCOME MEASURES Change in minutes of after-school moderate-to-vigorous physical activity (MVPA), fitness (maximal oxygen consumption), and body mass index over 1 school year. RESULTS Participants (n = 156) were diverse (42% Latino, 32% Asian, and 12% African American) and 76 (49%) had a body mass index at or above the 85th percentile. There were no significant group differences in the change in physical activity, fitness, or weight status among all students. However, among students with a body mass index at or above the 85th percentile, SCORES significantly increased MVPA after school (3.4 min/d; 95% CI, 0.3-6.5) and on Saturdays (18.5 minutes; 95% CI, 3.4-33.6). CONCLUSIONS AND RELEVANCE Existing community-based programs such as SCORES can increase physical activity among low-income youth, particularly those most at risk for weight-related comorbidities. While evaluating existing programs presents special challenges, partnerships between communities, schools, and researchers are an important component of translational research to address obesity.

Abstract
The purpose of this study was to pilot test the Comics for Health program, a theory-based nutrition and physical activity intervention for children. Twelve after-school programs were randomized to either a theory-based (n = 37) or a knowledge-based (n = 34 children) version of the intervention. Pretests, posttests, and 3-month follow-up tests were administered to evaluate the programmatic effects on body mass index percentile, obesity-related behaviors, and constructs of social cognitive theory. Both interventions found significant, yet modest effects for fruit and vegetable consumption (P < .005), physical activities (P < .004), and water and sugar-free beverage consumption (P < .001) and self-efficacy for fruit and vegetable consumption (P < .015) and physical activities (P < .009).

Abstract
The purpose of this article was to review primary prevention interventions targeting childhood obesity implemented in the after school environment from 2006 and 2011. A total of 20 interventions were found from 25 studies. Children in the interventions ranged from kindergarten to middle schoolers, however a majority was in the 4th and 5th grades. Most of the interventions targeted both physical activity and dietary behaviors. Among those that focused on only one dimension, physical activity was targeted more than diet. The duration of the interventions greatly varied, but many were short-term or brief. Many interventions were also based on some behavioral theory, with social cognitive theory as the most widely used. Most of the interventions focused on short-term changes, and rarely did any perform a follow-up evaluation. A major limitation among after school interventions was an inadequate use of process evaluations. Overall, interventions resulted in modest changes in behaviors and behavioral antecedents, and results were mixed and generally unfavorable with regards to indicators of obesity. Recommendations for enhancing the effectiveness of after school based childhood obesity interventions are presented.

Abstract
Afterschool programs (3-6 pm, ASPs) represent a promising approach to promote physical activity (PA) and are positioned to make a substantial contribution to children’s overall daily PA. This article synthesizes both descriptive and intervention focused efforts aimed at describing/increasing PA within the ASP setting and outlines future directions for research. ASPs provide anywhere from 8 to 24 minutes of moderate-to-vigorous PA daily, with children accumulating between 2600 and 3200 steps per day. State and national organizations have developed policies related to PA in ASPs, but the limited available evidence indicates that ASPs are far from meeting PA policy goals. A total of 17 ASP PA intervention studies have been conducted, more than half (9/17) within ASPs that were initiated and developed by researchers. Based on the review of evidence, key strategies to increase PA include high-quality professional development training, allocating time in the ASP schedule for children to engage in sufficient amounts of PA, and tailoring the intervention to local conditions. Future directions should focus on evaluating these key strategies, conducting descriptive studies of common ASP characteristics nationally and their influence on children’s PA, evaluation/refinement of existing ASP PA curricula, cost-effectiveness of interventions, and identification of feasible PA policy goals.

Abstract
BACKGROUND Schools represent a key potential venue for addressing childhood obesity. OBJECTIVE To assess the feasibility of Power-Up, an after-school program to decrease obesity risk among African American children, using community-based participatory research (CBPR) principles. METHODS Teachers led 14 weekly nutrition and physical activity sessions during afterschool care at the Woodlawn Community School on Chicago's South Side. Forty African American children ages 5 to 12 participated; their 28 parents discussed similar topics weekly at pickup time, and families practiced relevant skills at home. Pre- and post-intervention anthropometrics, blood pressure, dietary measures, and health knowledge and beliefs for children and parents were compared in univariate analysis. RESULTS At baseline, 26% of children were overweight; 28% were obese. Post-intervention, mean body mass index (BMI) z scores decreased from 1.05 to 0.81 (p<.0001). Changes were more pronounced for overweight (-0.206 z-score units) than for obese children (-0.062 z-score units; p=.01). Girls decreased their combined prevalence of overweight/obesity from 52% to 46%; prevalence across these categories did not change for boys. The prevalence of healthful attitudes rose, including plans to "eat more foods that are good for you" (77% to 90%; p=.027) and "planning to try some new sports" (80% to 88%; p=.007). CONCLUSION Children in the Power-Up program reduced mean BMI z scores significantly. The after-school venue proved feasible. The use of CBPR principles helped to integrate Power-Up into school activities and contributed to likelihood of sustainability. Engaging parents effectively in the afterschool time frame proved challenging; additional strategies to engage parents are under development. Plans are underway to evaluate this intervention through a randomized study.

Abstract
OBJECTIVES The objective of this study was to investigate trends in prevalence of high BMI from 2001 to 2008 and examine racial/ethnic disparities. METHODS Records for a total of 8 283 718 fifth-, seventh-, and ninth-grade students who underwent California's school-based BMI screening between 2001 and 2008 were included. Logistic regression identified trends in prevalence of high BMI (>or=85th, >or=95th, >or=97th, and >or=99th percentiles). RESULTS For 3 of 4 BMI cut points, prevalence continued to increase for black and American Indian girls through 2008, Hispanic girls plateaued after 2005, non-Hispanic white girls declined to 2001 prevalence levels after peaking in 2005, and Asian girls showed no increases. Non-Hispanic white boys peaked in 2005, then declined to 2001 prevalence levels for all BMI cut points; Hispanic and Asian boys declined after 2005 (for 3 lowest BMI cut points only) but remained above 2001 levels; and American Indian boys peaked later (2007) and declined only for BMI>or=95th. No girls and few boys showed a decline after peaking in prevalence of BMI>or=99th percentile. In 2008, disparities in prevalence were greatest for BMI>or=99th percentile, with prevalence of 4.9% for American Indian girls and 4.6% for black girls versus 1.3% for non-Hispanic white girls. CONCLUSIONS On the basis of statewide California data, prevalence of high BMI is declining for some groups but has not declined for American Indian and black girls. These trends portend greater disparities over time, particularly in severe obesity. Interventions and policies that are tailored to the highest risk groups should be pursued.
