    Input: OBJECTIVE . The objective of this study was to determine whether a generalizable best- practice individualized behavioral intervention  reduced BMI z score relative to st and ard dietetic care among overweight children . METHODS . The design consisted of an assessor-blinded , r and omized , controlled trial involving 134 overweight children ( 59 boys , 75 girls ; BMI ≥ 98th centile relative to United Kingdom 1990 reference data for children aged 5–11 years ) who were r and omly assigned to a best- practice behavioral program ( intervention ) or st and ard care ( control ) .  The intervention used family-centered counseling and behavioral strategies to modify diet , physical activity , and sedentary behavior . BMI z score , weight , objective ly measured physical activity and sedentary behavior , fat distribution , quality of life , and height z score were recorded at baseline and at 6 and 12 months . RESULTS . The intervention had no significant effect relative to st and ard care on BMI z score from baseline to 6 months and 12 months . BMI z score decreased significantly in both groups from baseline to 6 and 12 months . For those who complied with treatment , there was a significantly smaller weight increase in those in the intervention group compared with control subjects from baseline to 6 months . There were significant between-group differences in favor of the intervention for changes in total physical activity , percentage of time spent in sedentary behavior , and light-intensity physical activity . CONCLUSIONS . A generalizable , best- practice individualized behavioral intervention had modest benefits on objective ly measured physical activity and sedentary behavior but no significant effect on BMI z score compared with st and ard care among overweight children . The modest magnitude of the benefits observed perhaps argues for a longer-term and more intense intervention , although such treatments may not be realistic for many health care systems OBJECTIVE : To determine whether a 2-year family-based intervention using frequent contact and limited expert involvement was effective in reducing excessive weight compared with usual care . METHODS : Two hundred and six overweight and obese ( BMI ≥85th percentile ) children aged 4 to 8 years were r and omized to usual care ( UC ) or tailored package ( TP ) sessions at university research rooms . UC families received personalized feedback and generalized advice regarding healthy lifestyles at baseline and 6 months . TP families attended a single multidisciplinary session to develop specific goals suitable for each family , then met with a mentor each month for 12 months , and every third month for another 12 months to discuss progress and provide support . Outcome measurements ( anthropometry , question naires , dietary intake , accelerometry ) were obtained at 0 , 12 , and 24 months . RESULTS : BMI at 24 months was significantly lower in TP compared with UC children ( difference , 95 % confidence interval : –0.34 , –0.65 to –0.02 ) , as was BMI z score ( –0.12 , –0.20 to –0.04 ) and waist circumference ( –1.5 , –2.5 to –0.5 cm ) . TP children consumed more fruit and vegetables ( P = .038 ) and fewer noncore foods ( P = .020 ) than UC children , and fewer noncore foods were available in the home ( P = .002 ) . TP children were also more physically active ( P = .035 ) . No differences in parental feeding practice s , parenting , quality of life , child sleep , or behavior were observed . CONCLUSIONS : Frequent , low-dose support was effective for reducing excessive weight in predominantly mild to moderately overweight children over a 2-year period . Such initiatives could feasibly be incorporated into primary care Background : The WATCH IT programme was developed to address the needs of obese children from disadvantaged communities in Leeds and has been running since January 2004 . Results of the pilot phase , prior to a r and omised controlled trial , are presented . Methods : A process evaluation to assess success of implementation was conducted in December 2004 . User views ( parent and child ) were obtained by semi-structured interviews and focus groups . Change in BMI SD score was calculated for children attending between January 2004 and November 2005 . Results : A total of 94 children ( 49 girls , 45 boys ) , mean age ( SD ) 12.2 ( 2.0 ) years attended . They were moderately to severely obese ( mean BMI SDS 3.09 ( 0.45 ) , with low quality of life and self-image scores . There was a significant reduction in overweight at 6 months ( Δ BMI SD −0.07 ) , especially for teenagers ( Δ BMI SD −0.13 ) and girls ( Δ BMI SD −0.07 ) . The programme was successfully implemented . By December 2004 mean attendance was 2.1 ( 0.7 ) clinics per month , and sports sessions 3.3 ( 1.7 ) sessions per month . Fourteen children dropped out and non-attendance was low ( only 7.5 % sessions missed in 12 months ) . Qualitative research indicated significant appreciation of the service , with reported increase in self-confidence and friendships , and reduction in self-harm . Conclusion : WATCH IT offers a model for a community based service for obese children . The programme suggests that effective care can be delivered by health trainers supervised by health professionals , and so potentially provides a cost effective programme within children ’s communities . These findings are encouraging , and need to be substantiated by extension to other locations and evaluation by r and omised controlled trial OBJECTIVE There is a great need for solution-oriented studies and descriptions of interventions for pediatric obesity in real-world setting s. This report describes a group-based behavioral parent-only intervention to promote healthier lifestyle habits and reduce weight status in an obese 12-year-old female participant . METHOD The behavioral parent-only intervention program described was part of a r and omized controlled trial that evaluated the impact of 2 behavioral interventions that addressed dietary intake , physical activity , and weight status in overweight and obese youth living in rural setting s. Both the child and parent were targeted for behavior change . The intervention included 12 group sessions over 4 months . Behavioral strategies , including self-monitoring , goal setting , performance feedback , reinforcement , stimulus control , and instruction in behavioral parenting strategies were flexibly applied to meet the needs of the family . Assessment s were completed at baseline , month-4 posttreatment , and month-10 follow-up . RESULTS The parent attended 10 of 12 treatment sessions . At follow-up the child had lost 17 pounds and grew 1.7 in . in height . The child also experienced improved quality of dietary intake and a drop in the number of self-reported unhealthy weight control behaviors . The parent experienced no notable decrease or increase in BMI . CONCLUSIONS The report describes the successful application of a behavioral intervention to address pediatric obesity that uses a parent-only approach . It is hoped that this presentation will facilitate discussion and help encourage further presentations of how the flexible application of evidence d-based interventions can be applied in real-world setting To decrease BMI in overweight and obese children , improved dietary intake and increased physical activity are key elements . Our objective was to evaluate the impact of a 1-y food and physical activity intervention on energy and macronutrient intake in overweight and obese children . A r and omized open trial was conducted with 92 overweight or obese 10.4 ± 1.08-y-old children . The intervention included 14 group sessions with different themes regarding food and physical activity . Dietary intake was assessed with diet history interviews covering 14 d at baseline and 4-d food records after 1 y and was evaluated according to national dietary recommendations . The control group participated in the same measurements as the intervention group but did not take part in group sessions . After 1 y , both groups had decreased their energy intake ( EI ) relative to total energy expenditure , but the effect was more pronounced for the intervention group than for the control group . At 1 y follow-up , a larger proportion of children in the intervention group compared with the control group met the recommended intake of refined sugar ( P = 0.019 ) . However , the groups did not differ in the proportion children who met the recommended intake of dietary fiber . Further , SFA intake relative to total EI did not differ between the groups at 1 y follow-up . In conclusion , despite a rather comprehensive intervention , only modest effects were achieved with respect to reduced EI and improved macronutrient intake Background / Objectives : To determine if a multi-component family focused education package is more effective than a waiting list control group in treating overweight and obese children . Subjects/ Methods : A 2-year r and omised controlled trial ; 65 overweight and obese children aged 6–14 years were allocated to active intervention in either the first or second year , with body composition monitoring alone in the control period . Anthropometric measurements were undertaken at six monthly intervals and a 7-day food and activity diary were issued . Results : Over the 2 years of the study body mass index ( BMI ) SDS ( z score ) fell significantly in the intervention/control ( I/C ) group , but not in the control/intervention ( C/I ) group . The difference between groups was 0.3 , which was borderline significant ( 95 % confidence interval ( 95 % CI ) −0.62 to 0.02 , P=0.06 ) before adjusting for potential confounding factors . Thirty-three percent of the I/C group and 12 % of the C/I group achieved the target reduction of 0.5 BMI SDS . The I/C group had a significantly greater reduction in the percentage with a BMI above the 99.6th centile at 24 months ( P=0.04 ) and gained 5.7 kg less over the time of the study . There were no significant differences between groups for mean percentage attendance at physical activity sessions ( I/C group=24.1 % , 95 % CI , 15.4–32.9 ; C/I group=31.7 % , 95 % CI , 22.4–41.1 , P=0.229 ) . Conclusions : Children given active intervention followed by body composition monitoring alone reduced their BMI SDS , and fewer children were classified as grossly overweight by the end of the study . If these findings are true , there are important implication s for the provision of services managing overweight in the community Background This study evaluates the effects of an intervention performed by youth health care professionals on  child health behaviors .  The intervention consisted of offering healthy lifestyle counseling to parents of overweight ( not obese ) 5-year-old children . Effects of the intervention on the child having breakfast , drinking sweet beverages , watching television and playing outside were evaluated . Methods Data were collected with the ' Be active , eat right ’ study , a cluster r and omized controlled trial among nine youth health care centers in the Netherl and s. Parents of overweight children received lifestyle counseling according to the intervention protocol in the intervention condition ( n = 349 )  and usual care in the control condition ( n = 288 ) . Parents completed question naires regarding demographic characteristics , health behaviors and the home environment at baseline and at 2-year follow-up . Cluster adjusted regression models were applied ; interaction terms were explored . Results The population for analysis consisted of 38.1 % boys ; mean age 5.8 [ sd 0.4 ] years ; mean BMI SDS 1.9 [ sd 0.4 ] . There were no significant differences in the number of minutes of outside play or television viewing a day between children in the intervention and the control condition . Also , the odds ratio for having breakfast daily or drinking two or less glasses of sweet beverages a day showed no significant differences between the two conditions . Additional analyses showed that the odds ratio for drinking less than two glasses of sweet beverages at follow-up compared with baseline was significantly higher for children in both the intervention ( p < 0.001 ) and the control condition ( p = 0.029 ) . Conclusions Comparison of the children in the two conditions showed that the intervention does not contribute to a change in health behaviors . Further studies are needed to investigate opportunities to adjust the intervention protocol , such as integration of elements in the regular well-child visit . The intervention protocol for youth health care may become part of a broader approach to tackle childhood overweight and obesity . Trial registration Current Controlled Trials IS RCT BACKGROUND Comparative effectiveness research ( CER ) evidence on childhood obesity provides the basis for effective screening and management strategies in pediatric primary care . The uses of health information technology including decision support tools in the electronic health records ( EHRs ) , as well as remote and mobile support to families , offer the potential to accelerate the adoption of childhood obesity CER evidence . METHODS / DESIGN The Study of Technology to Accelerate Research ( STAR ) is a three-arm , cluster-r and omized controlled trial being conducted in 14 pediatric offices in Massachusetts design ed to enroll 800 , 6 to 12 year old children with a body mass index ( BMI ) ≥ 95th percentile seen in primary care at those practice s. We will examine the extent to which computerized decision support tools in the EHR delivered to primary care providers at the point of care , with or without direct-to-parent support and coaching , will increase adoption of CER  evidence for management of obese children . Direct-to-parent intervention components include telephone coaching and twice-weekly text messages . Point-of-care outcomes include obesity diagnosis , nutrition and physical activity counseling , and referral to weight management . One-year child-level outcomes include changes in BMI and improvements in diet , physical activity , screen time , and sleep behaviors , as well as cost and cost-effectiveness . CONCLUSIONS STAR will determine the extent to which decision support tools in EHRs with or without direct-to-parent support will increase adoption of evidence -based obesity management strategies in pediatric practice and improve childhood obesity-related outcomes Objective : The aim of the study was to compare the efficacy of group treatment stressing a health-promoting lifestyle with routine counseling in the treatment of childhood obesity . Design and subjects : 
    Output:
    
Three important mechanisms were present in all the most effective interventions but absent in all the least effective : 1/ showing families how to change : a ) providing child physical activity sessions , b ) delivering practical behaviour change strategy sessions , c ) providing calorie intake advice ; 2/ ensuring all the family are on board : a ) delivering discussion /education sessions for both children and parents , b ) delivering child-friendly sessions , c ) aim ing to change behaviours across the whole family ; 3/ enabling social support for both parents and children by delivering both child group sessions and parent group sessions .
To conclude , programmes should ensure the whole family is on board the programme , that parents and children can receive social support and are not just told what to change , but shown how
