Background Telehealth offers opportunities to extend clinical and research interventions for pediatric obesity. Objectives To assess utility of a telephone intervention, implemented through a national primary care pediatric research network, for promoting differentiation in dietary intake, consistent with either a low-glycemic load (Low GL) or Low Fat prescription, among overweight/obese school-age children. Methods Five-week telephone dietary counseling intervention for parents of overweight/obese school-age children recruited through the Slone Center Office-based Research Network. Parent-child dyads were randomized to Low GL or Low Fat diet. Primary outcomes were dietary GL and dietary fat, adjusted for energy intake and assessed by 24-hour dietary recall. Results Subjects were randomized to Low GL (n=11, 8.1±1.7 years, 45.5% male) or Low Fat (n=11, 8.2±2.0 years, 36.4% male), with no baseline differences. Overall, 86% of subjects attended at least 4 of 5 counseling sessions, and study completion rate was 91% (based on completion of the final dietary recalls). Reported satisfaction was high. In adjusted analyses limited to “recall completers,” reduction in dietary GL (g/1000 Kcal) achieved within the Low GL group was significant (p=0.01) and greater than the change in dietary GL in the Low Fat group (mean ± SE; −12.9 ± 4.4 vs. 5.1 ± 4.9, p=0.03). Similarly, reduction in dietary fat (% of total energy) within the Low Fat group was significant (−5.6 ± 2.5, p=0.046) but with no difference between groups (p=0.25). Conclusion A telephone-based dietary intervention for overweight/obese children, implemented through a national pediatric research network, fostered prescribed dietary changes.

“…‘Healthy Habits’ is a randomised controlled trial of a telephone-based parent intervention targeting parent and home food environment characteristics as a means of improving child diet [26]. The aim of the present study was to assess the effectiveness of the intervention in reducing child consumption of non-core foods, a secondary outcome investigated in the trial.…”

BackgroundConsumption of non-core foods in childhood is associated with excessive weight gain in childhood. Parents play a vital role in establishing healthy diet behaviours in young children. The aim of this study was to assess the effectiveness of a telephone-based intervention in reducing child consumption of non-core foods, and to examine parent and home food environment mediators of change in child consumption.MethodsThe ‘Healthy Habits’ trial utilised a clustered randomised controlled design.Setting/participantsParents were recruited from 30 preschools (N = 394 participants, mean age 35.2±5.6 years). Parents randomized to the intervention group received four telephone contacts and print materials. Parents allocated to the control condition receive generic print materials only. Non-core food consumption was assessed using a validated child dietary questionnaire at baseline, 2 and 6 months post recruitment in 2010.ResultsThe intervention was effective in reducing child consumption of non-core foods at 2 months (intention to treat analysis: z=-2.83, p<.01), however this effect was not maintained at 6 months. Structural equation modelling using 2 month data indicated that child access to non-core foods in the home and child feeding strategies mediated the effect of the intervention.ConclusionThe telephone-based intervention shows promise in improving short term dietary behaviour in preschool age children, however further development is needed to sustain the effect in the long-term.Trial registrationAustralian Clinical Trials Registry: ACTRN12609000820202

“…Paired t-tests will be conducted to determine whether there is a significant difference between the mean intakes of FV serves at baseline compared to the end of the intervention. significant increases in child FV intake, [17] there is no research on their effectiveness in this high-risk population of CCS; highlighting the unique contribution of the Reboot program. [40] We anticipate that the multimodal approach used in Reboot, encompassing a written parent guidebook and semi-structured telephone calls will contribute to the aim of the study.…”

“…[17] Following a familybased interventional model, parents act as important role models for children as well as being the primary regulators of the home food environment, which maintains children's eating behaviours. [25] In line with the original intervention, Reboot will be delivered individually to one parent (Table 1).…”
