OBJECTIVE To examine the differences in family eating behaviors and child eating patterns in children with siblings (nonsingletons) and without siblings (singletons). METHODS Cross-sectional analysis of mother-child dyads of 5-7-year-old children, (nonsingletons with a 2-to-4-year-old sibling) was conducted. Anthropometrics were measured. Mothers completed questionnaires and a child dietary log. Healthy Eating Index 2010 (HEI) score was calculated. Linear regression models adjusting for child age, child sex, maternal body mass index, and hours-away-from-home were conducted, with a revised P < .021. RESULTS Sixty-eight mother-child dyads (27 singletons, 41 nonsingletons) participated. Singletons exhibited less healthy family eating behaviors (β = -4.98, SE = 1.88, P = .003), and lower total HEI scores than did nonsingletons (average: β = -8.91, SE =2.40, P = .001). On average, singletons had lower scores in 3 HEI components compared with nonsingletons (P < .021 for all). CONCLUSION In this sample, singleton children exhibited less healthy eating behaviors. Additional investigation into parent-level differences is warranted.
