WHAT THIS STUDY ADDS:  This is the   󿬁rst study to reveal the ef 󿬁cacy of a low-intensity, 5-month, guided self-help treatment of  childhood obesity with effects on the target child ’s weight immediately posttreatment and 6 months later.

abstract BACKGROUND AND OBJECTIVE:   Clinic-based programs for childhood obesit obe sityy are not availab available le to a large large proport proportion ion of the pop popula ulatio tion. n. The purpose of this study was to evaluate the ef 󿬁cacy of a guided

self-h sel f-help elp treatm treatment ent of pediat pediatric ric obe obesit sityy (GS (GSH-P H-PO) O) compar compared ed with with a dela delayed yed treat treatmen mentt contro controll and to evalua evaluate te the imp impact act of GSH-PO GSH-PO 6-months posttreatment. METHODS:  Fifty overweight or obese 8- to 12-year-old children and  their parents were randomly assigned to immediate treatment or  to delayed treatment. The GSH-PO includes 12 visits over 5 months and addresses key components included in more intensive clinic-based progr programs ams.. Childr Children en and parent parentss in the imm immedia ediate te treatm treatment ent arm weree assess wer assessed ed at tim timee 1 (T1), (T1), particip participate ated d in GSH-PO GSH-PO between between T1 and T2, and completed their 6-month posttreatment assessment at T3. Children and parents in the delayed treatment arm were assessed at T1, participated in GSH-PO between T2 and T3, and completed their 66-mo mont nth h po post sttr trea eatm tmen entt as asse sess ssme ment nt at T4. T4. Th Thee main main ou outc tcom omee measures were BMI, BMI   z  score,  score, and percentage overweight (%OW). RESULTS: Children in the immediate treatment GSH-PO arm decreased  their BMI signi󿬁cantly more than did the delayed treatment arm (BMI group 3  time = 21.39;  P  , .001). Similar results were found for BMI   score and %OW. At the 6-month posttreatment assessment, changes z  score resulting resu lting from GSH-PO were maintained for BMI  z  score and %OW but not BMI (BMI time effect =   20.06, not signi󿬁cant; BMI   z  score time effect =   20.10,   P  ,  .001; %OW time effect =   24.86,   P   , .05). CONCLUSIONS: The GSH-PO showed initial ef 󿬁cacy in decreasing BMI for children in this study. Additional ef 󿬁cacy and translational studies are needed to additionally evaluate GSH-PO.  Pediatrics  2013;131:e1435   2013;131:e1435– e1442

DISCUSSION To our our kn know owled ledge, ge, this this is th thee   󿬁rst evaluation of a guided self-help treatment of overweight or obese children. The GSH-PO intervention showed a signi󿬁cant decrease in child BMI, BMI   z  sc scor ore, e, and and %OW im imme medi diat atel elyy af afte terr completing the 5-month treatment. In addition, addit ion, the intervention intervention resul resulted ted in decreases in child BMI   z  score   score and % OW tha thatt were were mai mainta ntained ined 6 months months after the intervention.

measures in this study. Recent reviews report rep ort biases biases in self-r self-repo eported rted mea mea-sures of diet in children,23 but there should be less bias in the accelerometer measurements. Studies in adults show that changes in diet are necessary for weight loss, whereas physical activity is more important for weight maintenance.24,25 We believe believe that the changes in body size in the children were most likely related to changes in  their diets, but these were likely to be in inac accu cura rate tely ly repo reporte rted, d, a wellwellrecognized limitation of self-reported dietary data. Intermsofparentoutcomes,therewere no statistically statistically signi󿬁can cantt change changess in parent BMI, diet, or physical activity in  this study. study. We allowed parent parent weight sta status tus to var varyy in our recruitm recruitment ent for this study, resulting in a sample of normalweightt and overweig weigh overweight ht parents parents.. However, we evaluated parent weight loss in only the overweight parents and found decrease of nearly .75 points in BMI for  the immediate immediate treatment treatment compar compared ed with delayed treatment group but did not have adequate statistical power to detect this betweenbetween-group group difference. difference. Parent diet and physical activity were measur meas ured ed by self-rep self-report ort instrum instruments ents and are also subject to bias. The GSH-PO intervention has a number of stren strength gths. s. It is a low-int low-intens ensity ity in tervention, which could be easily  translated to primary care providers or otherhealth careproviders.The GSH-PO intervention interve ntion provides provides 4.5 ho hour urss of  direct contact over 5 months, as opposed to the 30 hours of clinic familybased treatment programs.

GSH-PO empha emphasizes sizes   “self-help ”   and places less signi󿬁cance on the role of   the interventionist by shifting the emphasis to the individual family as the primary agent of change.

CONCLUSIONS This study revealed that the 5-month GSH-POinterventionresultsindecreases in BMI, BMI   z   score, and %OW in the  target child and maintenance of these losses at 6 months posttreatment. In addition, the intervention was well received by families, provides treatment in less time that that tradi traditio tional nal familyfamilybased treatment, and has the poten tial to be provided by health care providers in the future. The GSH-PO has  the potential to become the initial standard of care for overweight and obese children.

Primary care providers are often the gatewa gat ewayy to psych psycholog ologica icall treatm treatment ent because families typically do not seek  specia spe cialty lty psych psycholo ologic gical al servic services es as  their initial source of care. Because the GSH-PO is developed for dissemination
