Randomized Controlled Trial to Compare Growth Parameters and Nutrient Adequacy in Children with Picky Eating Behaviors who Received Nutritional Counseling with or without an Oral Nutritional Supplement

In this study, changes in growth parameters and nutrient intake were compared in Chinese children (ages 30-60 months) with picky eating (PE) behaviors and weight-for-height ≤25th percentile, who were randomized to receive nutrition counseling alone (NC; n = 76) or with a nutritional milk supplement (NC + NS; n = 77) for 120 days. Increases in weight-for-height z-scores were significantly greater in the NC + NS group at days 30 and 90 and over the entire study period (all P < 0.05), but not at day 120. Increases in weight-for-age z-scores were significantly greater in the NC + NS group at day 90 (P = 0.025) and over the entire study period (P = 0.046). Mean intakes of energy, protein, carbohydrate, docosahexaenoic acid, arachidonic acid, calcium, phosphorous, iron, zinc, and vitamins A, C, D, E, and B6 were significantly higher in the NC + NS group at days 60 and 120 (all P < 0.01). Thus, in young children with PE behaviors, nutritional supplementation given as an adjunct to NC resulted in greater improvements in nutrient intake compared with NC alone. Growth parameters differed between groups at several timepoints during the study, but not at day 120.
