Development and application of specific questions to classify a child as food texture sensitive.

Understanding food texture sensitivity in children is important in guiding food selection. The objective of this work was to develop a short questionnaire that could be completed by parents in nonclinical settings to provide a categorization for food texture sensitivity in children. This study evaluated the distribution of children as texture sensitive (TS) or non-texture sensitive (NTS) and the predictive validity of these questions to explain rejection of specific food textures. Three sets of survey data were examined, including data from a home-use test (HUT) in children with and without Down syndrome (DS), and lingual tactile sensitivity measured by grating orientation task (GOT). From three parent-completed surveys, the use of the questionnaire yielded a similar distribution of children in the TS category (16-22%) as previously reported. TS children (4-36 months) were more likely to reject specific food textures, including chewy, hard, lumpy, and "tough meat" (p < .05). A higher percentage of children with a diagnosis of DS were TS (36.9%). Children who were TS showed increased negative behaviors to foods and ate less than NTS children. In older children (5-12 years), TS children were fussier than NTS children (p < .001). Lingual tactile sensitivity was not significantly different by TS/NTS categorization (p = .458). This study demonstrated that the use of these five questions specific to food texture provides a useful tool in categorizing a child as TS/NTS, with this information being useful in selecting preferred food textures. Future studies involving these TS questions should perform psychometric assessments and measures of criterion validity using other questionnaires.

Development of a home-use method for the evaluation of food products by children with and without Down syndrome.

This article describes the development of a method to evaluate the acceptance of different snack food textures by children with food texture sensitivities, including children with and without Down syndrome (DS). An in-home use test (HUT) was developed to reflect recent taste study and allow greater recruitment. In this study, parents with children (ages 11-60 months) with DS (CWDS) and without (typically developing, CTD) were recruited and based on responses to several questions, children were categorized as food texture sensitive (TS) or nontexture sensitive (NTS). In total, 111 CWDS (49 TS and 62 NTS) and 107 CTD (42 TS and 65 NTS) participated. To select the food products for assessment, a trained panel profiled commercially available infant and toddler solid snack foods (n = 41), from which 16 products were selected and sorted into four flavor groupings. For the HUT, participating children evaluated each food product once per day for 6 days. Parents recorded their children's reactions to each food product; a panel of trained coders coded each video for verbal and nonverbal behaviors using a novel coding scheme. Parent prompts were also coded. Several challenges were experienced during this study, including poor-quality videos, and standardization of the home environment during the feeding sessions. However, the high degree of successful completion of the HUT (96%) was attributed to the high motivation of the parents involved, as well as the close interaction between the experimenters and the participants on an individual family level.

Parent-reported ease of eating foods of different textures in young children with Down syndrome.

Food texture has been identified as a significant contributor to feeding problems in children, particularly in children with Down syndrome (DS). This study examined the open-ended survey responses of parents describing which food textures were "easy" or "difficult" for their child with DS. The open-ended responses from the parents about textures and foods they considered "easy" or "difficult" for their child (n = 157) were coded into 26 texture categories. Chewy and firm were more frequently listed as "difficult" textures by parents. Textures found to be cited more frequently as "easy" textures included creamy, crispy/crunchy, dissolvable, mushy, puree, smooth, and soft. Age influenced the citation of specific textures. As age increased, crispy/crunchy, dry, and hard were more likely to be listed as "easy" while lumpy, mushy, and gooey/soggy/wet were less likely be listed as "easy." For "difficult" textures, as age increased, juicy was more likely to be listed as "difficult" while the textures of creamy, dry, lumpy, and tender were less likely to be "difficult." While this research provides information as to the food textures children with DS find "easy" or "difficult," further research is needed to better understand how to expand the variety of textures in the diets of children with DS.
