BACKGROUND: Parent-child diet quality resemblance is unknown in families of youth with type 1 diabetes, for whom nutrition is central to disease management. OBJECTIVE:Examine diet quality resemblance in families of youth with type 1 diabetes participating in a behavioral nutrition intervention trial and investigate whether treatment assignment or family meal frequency modifies resemblance. DESIGN: This is a secondary data analysis from an 18-month randomized controlled trial conducted August 2010 to May 2013. PARTICIPANTS/ SETTING:Parent-youth dyads (N=136, child age=12.3±2.5 years) were recruited from a northeast US diabetes center. MAIN OUTCOME MEASURES: Parent and child Healthy Eating Index-2005 (HEI-2005, reflecting adherence to 2005 Dietary Guidelines for Americans) and whole plant food density (WPFD, reflecting intervention target foods) were calculated from 3-day food records collected every 6 months. STATISTICAL ANALYSIS: Linear random effects models adjusting for demographics and disease characteristics investigated parent-child diet quality resemblance. Separate models examined whether treatment assignment or family meal frequency modified resemblance. Three-way interaction terms examined whether resemblance changed over time by treatment assignment. RESULTS:Time-varying parent and child HEI-2005 and WPFD were positively associated (P<0.001), and there were no interactions with family meals. Parent-child HEI-2005 resemblance was similar across treatment groups; however, parent-child WPFD resemblance was stronger in the intervention (β±standard error [SE]=.30±.06) vs control families (β±SE=.12±.05). Parent-child HEI-2005 resemblance was similar over time by treatment assignment, whereas parent-child WPFD resemblance increased over time for families in the intervention group (three-way interaction term β±SE=.03±.01). CONCLUSIONS:Parent and youth diet quality were positively correlated in families of youth with type 1 diabetes. Resemblance was stronger in the intervention group for target foods, but not for a general measure of diet quality. The lack of effect modification by family meal frequency suggests that family diet quality resemblance is not contingent on shared meals. Published by Elsevier Inc.
