Social-Emotional Functioning and Dietary Intake among Children Born with a Very Low Birth Weight

Very low birth weight infants (VLBW, <1500g) are at elevated risk of neurodevelopmental disorders, later obesity and cardiometabolic disease; if and how neurodevelopmental disorders impact chronic disease risk is poorly understood. The most common neurodevelopmental disorders experienced by VLBW children are those of social-emotional functioning. We compared dietary patterns and body composition between VLBW children with poor vs. typical social-emotional functioning using linear mixed models adjusted for sex, gestational age, cognitive impairment, parental education and BMI. VLBW children (n=158) attending the Donor Milk for Improved Neurodevelopmental Outcomes trial 5.5-year follow-up participated. Poor social-emotional functioning was based on standardized parent-rated questionnaires and/or parent-reported physician diagnosis of autism spectrum or attention-deficit/hyperactivity disorders. Most children had diets categorized as 'needs improvement' (67%) or 'poor' (27%) and 29% of children exhibited poor social-emotional functioning. Poor social-emotional functioning was positively associated with 100% fruit juice (β=0.3 cup equivalents/day; 95% CI 0.1, 0.5) and energy intake (β=118.1 kcals/day; 95% CI 0.9, 235.2). Children with poor social-emotional functioning were more likely to have a limited food repertoire (p=0.02), but less likely to exceed dietary fat recommendations (p=0.04). No differences in overall diet quality or body composition were observed. Diet counselling and research are essential to improving the nutrition of VLBW children to mitigate chronic disease risk. Novelty: • Overall diet quality and body composition did not differ between VLBW children with poor vs. typical social-emotional functioning. • Most had diets “needing improvement” or “poor” according to the HEI 2010. • Diet counselling may help mitigate chronic disease risk in this vulnerable population.
