Abstract
OBJECTIVE To evaluate the effects of whole-body vibration on fat, bone, leptin and muscle mass. METHODS/DESIGN Thirty 7-month-old female 344 Fischer rats were randomized by weight into three groups (baseline, vibration or control; n=8-10 per group). Rats in the vibration group were placed inside individual compartments attached to a Pneu-Vibe vibration platform (Pneumex, Sandpoint, ID, USA) and vibrated at 30-50 Hz (6 mm peak to peak) for 30 min per day, 5 days per week, for 12 weeks. The vibration intervention consisted of six 5-min cycles with a 1-min break between cycles. RESULTS There were significant body composition differences between the whole-body vibration and the control group. The whole-body vibration group weighed approximately 10% less (mean+/-s.d.; 207+/-10 vs 222+/-15 g, P<0.03) and had less body fat (20.8+/-3.8 vs 26.8+/-5.9 g, P<0.05), a lower percentage of body fat (10.2+/-1.7 vs 12+/-2.0%, P<0.05), and lower serum leptin levels (1.06+/-0.45 vs 2.27+/-0.57 ng ml(-1), P<0.01) than the age-matched controls. No differences were observed for total lean mass, bone mineral content (BMC), bone mineral density (BMD), insulin-like growth factor-I (IGF-I) or soleus (SOL) and extensor digitorum longus (EDL) mass or function. Regional high-resolution dual-energy X-ray absoptiometry scans of the lumbar spine (L1-4) revealed that the whole-body vibration group had significantly greater BMC (0.33+/-0.05 vs 0.26+/-0.03 g, P<0.01) and BMD (0.21+/-0.01 vs 0.19+/-0.01 g cm(-2), P<0.01) than the control group. No differences between the groups were observed in the amount of food consumed. CONCLUSION These findings show that whole-body vibration reduced body fat accumulation and serum leptin without affecting whole body BMC, BMD or lean mass. However, the increase in vertebral BMC and BMD suggests that vibration may have resulted in local increases in bone mass and density. Also, whole-body vibration did not affect muscle function or food consumption.

Abstract
PURPOSE Pediatric hyperlipidemia increases cardiovascular disease risk. The cornerstone of treatment is a restrictive, lipid-lowering diet. Child disease understandings and perceptions of dietary adherence were explored, a secondary aim of the Endothelial Assessment of Risk from Lipids in Youth trial. DESIGN AND METHODS Focus groups and individual interviews were conducted with participants, ages 9-20 years (n = 50). Data were thematically analyzed. FINDINGS Adherence is influenced by individual characteristics (developmental level, knowledge), in the context of social interactions (family modeling, peer relationships, school). PRACTICAL IMPLICATIONS Dietary practices are developed within social interactions. Interventions promoting adherence must consider children within their social contexts.

Reducing unhealthy weight gain in children through community capacity-building: results of a quasi-experimental intervention program, Be Active Eat Well. Int J Obes (Lond) 2008; 32:1060-7.

Abstract
BACKGROUND Be Active Eat Well (BAEW) was a multifaceted community capacity-building program promoting healthy eating and physical activity for children (aged 4-12 years) in the Australian town of Colac. OBJECTIVE To evaluate the effects of BAEW on reducing children's unhealthy weight gain. METHODS BAEW had a quasi-experimental, longitudinal design with anthropometric and demographic data collected on Colac children in four preschools and six primary schools at baseline (2003, n=1001, response rate: 58%) and follow-up (2006, n=839, follow-up rate: 84%). The comparison sample was a stratified random selection of preschools (n=4) and primary schools (n=12) from the rest of the Barwon South Western region of Victoria, with baseline assessment in 2003-2004 (n=1183, response rate: 44%) and follow-up in 2006 (n=979, follow-up rate: 83%). RESULTS Colac children had significantly lower increases in body weight (mean: -0.92 kg, 95% CI: -1.74 to -0.11), waist (-3.14 cm, -5.07 to -1.22), waist/height (-0.02, -0.03 to -0.004), and body mass index z-score (-0.11, -0.21 to -0.01) than comparison children, adjusted for baseline variable, age, height, gender, duration between measurements and clustering by school. In Colac, the anthropometric changes were not related to four indicators of socioeconomic status (SES), whereas in the comparison group 19/20 such analyses showed significantly greater gains in anthropometry in children from lower SES families. Changes in underweight and attempted weight loss were no different between the groups. CONCLUSIONS Building community capacity to promote healthy eating and physical activity appears to be a safe and effective way to reduce unhealthy weight gain in children without increasing health inequalities.

Abstract
BACKGROUND The translation and dissemination of prevention intervention evidence into practice is needed to address significant public health issues such as childhood obesity. Increased attention to and reporting of external validity information in research publications would allow for better understanding of generalizability issues relevant to successful translation. To demonstrate this potential, recent reports of childhood obesity prevention interventions were evaluated on the extent to which external validity dimensions were reported. METHODS Childhood obesity prevention studies that were controlled, long-term research trials published between 1980 and 2004 that reported a behavioral target of physical activity and/or healthy eating along with at least one anthropometric outcome were identified in 2005. Studies were summarized between 2005 and 2006 using review criteria developed by Green and Glasgow in 2006. RESULTS Nineteen publications met selection criteria. In general, all studies lacked full reporting on potential generalizability and dissemination elements. Median reporting over all elements was 34.5%; the mode was 0% with a range of 0% to 100%. Most infrequent were reports of setting level selection criteria and representativeness, characteristics regarding intervention staff, implementation of intervention content, costs, and program sustainability. CONCLUSIONS The evidence base for future prevention interventions can be improved by enhancing the reporting of contextual and generalizability elements central to translational research. Such efforts face practical hurdles but could provide additional explanation for variability in intervention outcomes, insights into successful adaptations of interventions, and help guide policy decisions.

Abstract
Background The literature on childhood and adolescent obesity is vast. In addition to producing a general overview, this paper aims to highlight gender differences or similarities, an area which has tended not to be the principal focus of this literature. Methods Databases were searched using the terms 'obesity' and 'child', 'adolescent', 'teenager', 'youth', 'young people', 'sex', 'gender', 'masculine', 'feminine', 'male', 'female', 'boy' and 'girl' (or variations on these terms). In order to limit the potential literature, the main focus is on other reviews, both general and relating to specific aspects of obesity. Results The findings of genetic studies are similar for males and females, and differences in obesity rates as defined by body mass index are generally small and inconsistent. However, differences between males and females due to biology are evident in the patterning of body fat, the fat levels at which health risks become apparent, levels of resting energy expenditure and energy requirements, ability to engage in certain physical activities and the consequences of obesity for the female reproductive system. Differences due to society or culture include food choices and dietary concerns, overall physical activity levels, body satisfaction and the long-term psychosocial consequences of childhood and adolescent obesity. Conclusion This review suggests differences between males and females in exposure and vulnerability to obesogenic environments, the consequences of child and adolescent obesity, and responses to interventions for the condition. A clearer focus on gender differences is required among both researchers and policy makers within this field.

Abstract
Child overweight has reached an epidemic level throughout the United States. A total of 65 primary care providers in southern Appalachia were surveyed to understand current issues in addressing child overweight in rural primary care practice. The study shows that while providers realized the importance of child overweight intervention, many were not ready and did little to address child overweight in their practices. The providers' skill levels in addressing child overweight were generally less than sufficient. Common barriers to child overweight treatment included lack of parental motivation and involvement, lack of supportive services, and lack of clinician time. In conclusion, rural primary care is facing many challenges in addressing child overweight. However, with more training in behavioral intervention skills and through establishing a family-based intervention and a group visit approach, primary care providers could play a more active role in the fight against the epidemic of child overweight.

Abstract
Rates of childhood overweight have reached epidemic proportions (U.S. Department of Health and Human Services, 2001), and schools have been called on to play a role in the prevention of this medical condition. This article describes a multiyear health promotion effort-the Athletes in Service fruit and vegetable (F&V) promotion program-which is based on social learning theory for urban, elementary school children in kindergarten through third grade. Children participate in the program for a period of 3 years. The goals of the program are to increase opportunities for children to be more physically active during the school day and to help students increase their F&V consumption. This article describes the F&V promotion components of the program that were implemented in year 1, including implementation integrity and treatment acceptability data. Year 1 evaluation data demonstrated that the program is acceptable from the perspective of school staff and was implemented by school staff with high levels of integrity. Hallmarks of the program's successful implementation and high acceptability include (a) having a school-based program champion; (b) designing the program to include low-cost, attractive, interactive materials; (c) including many school staff members to facilitate a culture of healthy eating in the school; and (d) spreading out implementation responsibilities among the multiple staff members so that each individual's involvement is time efficient.

Abstract
OBJECTIVE To assess reproducibility of a School-Based Nutrition Monitoring (SBNM) questionnaire for fourth-grade students. DESIGN Test-retest. SETTING Fourth-grade elementary school classrooms PARTICIPANTS Multiethnic fourth-grade students from 2 area school districts (N = 322). MAIN OUTCOME MEASURES Reproducibility coefficients with time intervals between questionnaire administrations of 2 hours for the yesterday food choice and physical activity questions or 2 weeks for the nutrition knowledge and attitude questions. ANALYSIS Spearman rank order correlation, percent agreement, and Kappa statistic calculated for each individual questionnaire item. RESULTS Of 43 questions that were included in the reproducibility analyses, test-retest kappa values were moderate to high (greater than 0.40) for more than 90% of the questions (39 questions). Spearman coefficients were greater than 0.70 for 24 questions, whereas percent agreement exceeded 75% for 28 questions. CONCLUSIONS AND IMPLICATIONS The SBNM questionnaire showed good to excellent reproducibility for nutrition behavior questions, physical activity, weight behavior, and food selection skills overall. However, questions that assessed nutrition knowledge and attitudes were not as reproducible, probably resulting from learning effects over time. Results from the study indicate that this questionnaire can be easily administered in an elementary school classroom and can be used to measure nutrition behaviors among 9- to 10-year-old school children.

Abstract
Rates of pediatric obesity have increased dramatically over the past decade. This trend is especially alarming because obesity is associated with significant medical and psychosocial consequences. It may contribute to cardiovascular, metabolic, and hepatic complications, as well as to psychiatric difficulties. The development of obesity appears to be influenced by a complex array of genetic, metabolic, and neural frameworks, along with behavior, eating habits, and physical activity. Numerous parallels exist between obesity and addictive behaviors, including genetic predisposition, personality, environmental risk factors, and common neurobiological pathways in the brain. Typical treatments for pediatric obesity include behavioral interventions targeting diet or exercise. These treatments have yielded mixed results and typically have been examined in specialty clinic populations, limiting their generalizability. There are limited medication options for overweight children and adolescents, and no approved medical intervention in children younger than 16 years old. Bariatric surgery may be an option for some adolescents, but due to the risks of surgery, it is often seen as a last resort. The parallels between addiction and obesity aid in developing novel interventions for pediatric obesity. Motivational enhancement and cognitive-behavioral strategies used in addiction treatment may prove to be beneficial.

Abstract
In this article, we review evidence about the treatment of obesity that may have applications in primary care, community, and tertiary care settings. We examine current information about eating behaviors, physical activity behaviors, and sedentary behaviors that may affect weight in children and adolescents. We also review studies of multidisciplinary behavior-based obesity treatment programs and information about more aggressive forms of treatment. The writing group has drawn from the available evidence to propose a comprehensive 4-step or staged-care approach for weight management that includes the following stages: (1) Prevention Plus; (2) structured weight management; (3) comprehensive multidisciplinary intervention; and (4) tertiary care intervention. We suggest that providers encourage healthy behaviors while using techniques to motivate patients and families, and interventions should be tailored to the individual child and family. Although more intense treatment stages will generally occur outside the typical office setting, offices can implement less intense intervention strategies. We not ony address specific patient behavior goals but also encourage practices to modify office systems to streamline office-based care and to prepare to coordinate with professionals and programs outside the office for more intensive interventions.

Abstract
OBJECTIVE The objective was to describe the pattern of breakfast eating over time ("breakfast history") and examine its associations with BMI and physical activity. RESEARCH METHODS AND PROCEDURES This longitudinal investigation of patterns of breakfast eating included 1,210 black and 1,161 white girls who participated in the 10-year, longitudinal National Heart, Lung, and Blood Institute Growth and Health Study (NGHS). Three-day food records were collected during annual visits beginning at ages 9 or 10 up to age 19. Linear regression and path analysis were used to estimate the associations between breakfast history, BMI, and physical activity. RESULTS Among girls with a high BMI at baseline, those who ate breakfast more often had lower BMI at the end of the study (age 19), compared with those who ate breakfast less often. Path analysis indicated that energy intake and physical activity mediated the association between patterns of breakfast eating over time and BMI in late adolescence. DISCUSSION The association between regular breakfast consumption over time and moderation of body weight among girls who began the study with relatively high BMI suggests that programs to address overweight in children and adolescents should emphasize the importance of physical activity and eating breakfast consistently.

Abstract
The need has never been greater to support healthy eating and physical activity in children and youth; the numbers of overweight and obese children have doubled and tripled, respectively, over the past 3 decades. Poor eating habits, including inadequate intake of vegetables, fruit, and milk, and eating too many high-calorie snacks, play a role in childhood obesity. Grain products provide the highest percentage (31%) of daily calories, followed by “other foods,” which have limited nutritional value (22% of daily calories). Snacks account for 27% of total daily calories, which is more than the calories consumed at breakfast (18%) and lunch (24%), but not dinner (31%). For Canadians older than 4 years of age, more than 41% of daily snack calories come from other foods, such as chips, chocolate bars, soft drinks, fruit drinks, sugars, syrup, preserves, fats, and oils. Habits that protect against childhood obesity include eating more vegetables and fruit, eating meals with family, and being physically active. Children’s food habits and choices are influenced by family, caregivers, friends, schools, marketing, and the media. Successful interventions for preventing childhood obesity combine family- and school-based programs, nutrition education, dietary change, physical activity, family participation, and counseling.

Abstract
OBJECTIVE To identify effective programs to prevent or treat overweight among 2- to <6-year-old children. RESEARCH METHODS AND PROCEDURES We searched six databases to identify evaluated intervention programs assessing changes in weight status or body fat and systematically summarized study attributes and outcomes. RESULTS Four of the seven studies (two intervention, two prevention) documented significant reductions in weight status or body fat. Among these, three sustained reductions at 1 or 2 years after program initiation, three incorporated a framework/theory, two actively and one passively involved parents, three included multicomponent strategies, and all four monitored behavioral changes. Of the three (prevention) studies that did not show reduction in weight or fat status, all performed assessments between 4 and 9 months after program initiation, and one used a multicomponent strategy. Other significant changes reported were reductions in television viewing, cholesterol, and parental restriction of child feeding. DISCUSSION The paucity of studies limits our ability to generalize findings. Among the available studies, multicomponent programs with 1- to 2-year follow-up in clinics or child care settings were successful in their impact on weight; they were likely enhanced by parental involvement. Both treatment programs and two of five prevention programs reduced weight/fat status. Our review highlights the need to evaluate more programs, advocate for use of a framework/behavioral theory and objective behavioral measures, further examine the impact of involving parents and the impact of intervention duration and follow-up time, strengthen prevention programs, and further evaluate successful programs in other settings and among other racial/ethnic groups.

Abstract
The most prevalent disordered eating pattern described in overweight youth is loss of control (LOC) eating, during which individuals experience an inability to control the type or amount of food they consume. LOC eating is associated cross-sectionally with greater adiposity in children and adolescents and seems to predispose youth to gain weight or body fat above that expected during normal growth, thus likely contributing to obesity in susceptible individuals. No prior studies have examined whether LOC eating can be decreased by interventions in children or adolescents without full-syndrome eating disorders or whether programs reducing LOC eating prevent inappropriate weight gain attributable to LOC eating. Interpersonal psychotherapy, a form of therapy that was designed to treat depression and has been adapted for the treatment of eating disorders, has shown efficacy in reducing binge eating episodes and inducing weight stabilization among adults diagnosed with binge eating disorder. In this paper, we propose a theoretical model of excessive weight gain in adolescents at high risk for adult obesity who engage in LOC eating and associated overeating patterns. A rationale is provided for interpersonal psychotherapy as an intervention to slow the trajectory of weight gain in at-risk youth, with the aim of preventing or ameliorating obesity in adulthood.

Abstract
Changes in physical activity with the aim of increasing energy expenditure are usually an important component of childhood obesity treatment. Physical activity also has several other aspects that are positive for the obese child's health, such as improving the metabolic profile and psychological well being. The aim of this paper is to give a short review of what we know about physical activity in paediatric obesity treatment. In addition, practical recommendations will be presented which a health care provider can suggest to obese children and their families with a special focus on daily activity, participation in physical education classes and sports, sedentary behaviours, active commuting to school and how to get family and friends involved in supporting the child.

Abstract
OBJECTIVE The Wise Mind pilot study compared the efficacy of an environmental approach for prevention of inappropriate weight gain in children with an active control condition that used an environmental approach for modifying expectancies related to the use of alcohol, tobacco, and drugs. RESEARCH METHODS AND PROCEDURES A total of 670 second to sixth grade students from four schools were enrolled in the study. The study spanned 2 academic years, and 586 students were available for evaluation at the end of the study. Two schools were randomly assigned to each treatment arm. The environmental approach for weight gain prevention focused on modification of eating habits and physical activity, and the active control group focused on modification of expectancies related to substance use. RESULTS Using an intention to treat design, the study found no differences in weight gain prevention between the two interventions. The weight gain prevention program was associated with reduction of total caloric intake, reduction of dietary fat intake, reduction of protein intake, and increased physical activity in comparison with the active control group and relative to baseline. These changes in food intake were attributed to changes in food selections that resulted from modification of school cafeteria menus and food preparation. DISCUSSION The Wise Mind school-based weight gain prevention program induced behavioral changes in healthy eating and physical activity but did not induce significant changes in body weight in comparison with the control arm. Recommendations for future research are provided.

Abstract
Multiple and diverse preventive strategies in clinical and community settings are necessary to improve health. This paper (1) introduces evidence-based recommendations from the U.S. Preventive Services Task Force sponsored by the Agency for Healthcare Research and Quality and the Community Task Force sponsored by the Centers for Disease Control and Prevention, (2) examines, using a social-ecologic model, the evidence-based strategies for use in clinical and community settings to address preventable health-related problems such as tobacco use and obesity, and (3) advocates for prioritization and integration of clinical and community preventive strategies in the planning of programs and policy development, calling for additional research to develop the strategies and systems needed to integrate them.

Abstract
PURPOSE OF REVIEW Physical activity has been highlighted internationally as a beneficial intervention for weight control and the improvement of physical and mental health. This review highlights findings from recent literature to guide office-based promotion of physical activity for obesity treatment and prevention. RECENT FINDINGS Children worldwide participate in far less than the current physical activity recommendations. Family-based activity provides children with positive role modeling as well as motivational support for maintaining an active lifestyle. The integration of physical activity into daily life can be an effective alternative to sports and structured exercise programs. Decreasing sedentary behaviors is also a positive contribution, although its link to physical activity levels is still unclear. Some families may see neighborhood safety and access to recreational facilities as barriers to keeping their children physically active. SUMMARY Research in the field of pediatric obesity and overweight treatment and prevention continues to find challenges and solutions. Promotion of physical activity by the pediatric provider is demonstrated by current evidence to be a positive intervention against this global problem.
