Abstract
Objectives
The objective of this pilot study was to test the feasibility of implementing a mobile health intervention, “Nutricity,” within pediatric well-care and explore outcomes on child diet quality, child BMI and parental nutrition literacy.
Methods
Participants in this single-arm intervention pilot study were 18 parent-child dyads recruited from pediatric primary care before a scheduled well-care visit. Parents were English-speaking, identified as primary food decision-maker, had internet access at home, and owned a web-enabled device; children were 1–5 years old with unrestricted diets. Dyads were given three months’ access to Nutricity mobile tools during the child's well-care visit and were guided on use. Nutricity tools included a mobile formatted website to access instructional videos, games for kids, and quizzes for parents, and weekly text messages for nutrition goal setting. Content was focused on applying nutrition information at supermarkets, home, and restaurants. Feasibility was evaluated by % completion, parent likability survey, website usage, and % text responses logged. At baseline and three months, parent nutrition literacy (Nutrition Literacy Assessment Instrument, NLit); diet quality (2,24-hour diet recalls used to calculate a Healthy Eating Index, HEI – 2015 score), and BMI were collected with differences analyzed by paired t-tests.
Results
Of 18 dyads enrolled, 17 (94%) completed the study. Parents rated likability of the website and text messages as ‘good-excellent,’ reporting they applied ‘half-most’ of goals set through text-messaging. A common emergent theme was need for more individualized text messages. Mean response rate to text messages was 62%, and dyads logged an average of 43.7 minutes and 5.2 sessions on the website. Non-significant improvements were seen in parent NLit and overall child HEI scores, and no difference was seen in child BMI. However, HEI component scores improved for dairy by 1.2 points (P = .055) and seafood/plant proteins by 1.3 points (P = 0.046).
Conclusions
Delivering Nutricity via a pediatric well-care visit is feasible and demonstrated potential for improving child diet quality. A larger, adequately powered study is warranted.
