Abstract

Although children's dietary intake often resembles that of their parents', dietary resemblance has not been examined among children with intellectual disabilities (ID), where food selectivity is a common parental concern. We compared dietary resemblance in children with typical development (TD), ID, and ID and co-occurring autism (ID + A) in parent-child dyads, and examined whether child food selectivity mediated between-group differences. Dietary data from parents and their children (3–8 years, male = 61.8%, TD = 52.9%, ID = 18.6%, ID + A = 28.4%) were analyzed as mother-child (n = 100) and father-child (n = 70) dyads. Dietary resemblance was operationalized as the proportion of foods that were reported as eaten/not eaten by both parent and child in parent-completed Food Frequency Questionnaires. Food refusal rate was used to capture food selectivity (total foods children would not eat/total foods offered). Among mother-child dyads, dietary resemblance did not differ between children with ID compared to TD (P = 0.243). Among father-child dyads, dietary resemblance was 10% lower in children with ID than TD (66.4% vs. 74.1%, P = 0.032), and the difference was partially explained (mediated) by food refusal. Among mother-child dyads, dietary resemblance was 19% lower among children with ID + A than TD (61.5% vs. 75.6%, P = 0.001), and the difference was completely explained by food refusal. Among father-child dyads, dietary resemblance was 22% lower among children with ID + A than TD (57.9% vs. 74.1%, P < 0.001), and the difference was completely explained by food refusal. Subanalyses by food groups produced similar results. Compared to TD children, dietary resemblance was lower in children with ID + A, but not children with ID, and differences were explained by food selectivity. Our findings suggest parents of children with ID + A may have less influence over their child's dietary intake than parents of children with ID or TD.

食物选择性是否会导致智障儿童与发育正常儿童之间的饮食相似性差异？

虽然儿童的饮食摄入量通常与父母的相似，但尚未研究过智障（ID）儿童的饮食相似性，而对食物的选择性是父母普遍关心的问题。我们比较了典型发育（TD）儿童、智障儿童、智障儿童和同时患有自闭症（ID + A）的儿童在亲子关系中的饮食相似性，并研究了儿童的食物选择性是否是组间差异的中介。对父母及其子女（3-8 岁，男性 = 61.8%，TD = 52.9%，ID = 18.6%，ID + A = 28.4%）的饮食数据进行了母子（n = 100）和父子（n = 70）二元组分析。膳食相似度是指在父母填写的食物频率调查表中，父母和子女均表示吃过/没吃过的食物比例。拒食率用于反映食物的选择性（儿童不吃的食物总数/提供的食物总数）。在母子二人组中，智障儿童与智障儿童的饮食相似度没有差异（P = 0.243）。在父子二人组中，智障儿童的饮食相似度比智障儿童低 10%（66.4% 对 74.1%，P = 0.032），而拒食可以部分解释（调节）这种差异。在母子二人组中，ID + A 患儿的饮食相似度比 TD 患儿低 19%（61.5% 对 75.6%，P = 0.001），拒绝进食可完全解释这一差异。在父子组合中，智障＋A 儿童的饮食相似度比智障儿童低 22%（57.9% 对 74.1%，P=0.001）。

期刊介绍： Appetite is an international research journal specializing in cultural, social, psychological, sensory and physiological influences on the selection and intake of foods and drinks. It covers normal and disordered eating and drinking and welcomes studies of both human and non-human animal behaviour toward food. Appetite publishes research reports, reviews and commentaries. Thematic special issues appear regularly. From time to time the journal carries abstracts from professional meetings. Submissions to Appetite are expected to be based primarily on observations directly related to the selection and intake of foods and drinks; papers that are primarily focused on topics such as nutrition or obesity will not be considered unless they specifically make a novel scientific contribution to the understanding of appetite in line with the journal's aims and scope.
