A Randomized Crossover Study to Evaluate Recipe Acceptability in Breastfeeding Mothers and Young Children in India Targeted for a Multiple Biofortified Food Crop Intervention
2019
A multiple biofortified food crop trial targeting iron, zinc, and vitamin A deficiencies among young children and their breastfeeding mothers is planned in India. To determine the acceptability of recipes prepared with control and biofortified pearl millet, wheat, lentils, and sweet potato. Children (6-24 months) and their mothers were enrolled as pairs (n = 52). Weight and height/length were determined. Mothers and children were separately, individually randomized in a crossover design to control or biofortified recipes. Children’s 3-day intake was measured per recipe and crop variety. For mothers, a 9-point hedonic scale evaluated color, odor, taste, and overall acceptability. Children’s mean (SD) length-/height-for-age Z-score was −1.2 (1.7), with 27% < −2 (stunted). Mean weight-for-length Z-score was −0.6 (1.2) with 9.6% < −2 (wasted). Mother’s body mass index showed 17% <18.5 and 38% >25. There was no difference in the children’s intake of biofortified versus control varieties of any recipe (P ≥ .22); overall median daily intake was 75 g (Q1: 61, Q3: 100). Mother’s hedonic scores for color, odor, taste, or overall acceptability did not demonstrate any notable differences (P ≥ .23 for overall acceptability); combined median overall acceptability score was 8.5 (Q1: 8.0, Q3: 9.0). Recipes were consumed readily, were rated as highly acceptable, and did not show any differences between biofortified and control varieties.
