Description: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. ClinicalTrials.gov registration: NCT00620152
