Abstract

Background: While complementary feeding can be challenging, little emphasis has been placed on the introduction to food texture/pieces, especially in terms of neurodevelopmental outcomes. This study aims to determine the association between the timing of introduction to food pieces during infancy and neurodevelopment in early childhood. We hypothesized that late introduction to food texture/pieces relates to unfavorable neurodevelopmental outcomes.

Methods: Families (n = 18329) were recruited from the general population during the nationwide ELFE (Étude Longitudinale Française depuis l'Enfance) birth cohort in France, and 8511 were selected for a complete case analysis. Age at introduction to food pieces was determined based on repeated assessments during the first year. A range of neurodevelopmental outcomes among children were assessed using validated instruments, i.e. composite scores at 1 and 3.5 years, and a score for language acquisition at 2 years. Risk for developmental delay at 3.5 years was defined based on a developmental quotient (DQ) below 90 according to the child's chronological age and the respective composite score at this age. We used linear regression modelling to evaluate associations between age at introduction to food pieces and the standardised neurodevelopmental scores, while logistic regression models were used in the analyses according to the risk for developmental delay.

Results: Our findings highlight consistent associations between late introduction to food pieces (i.e., after 10 months, compared to early (before 8 months)) and lower estimates of standardised neurodevelopmental scores at ages 1, 2 and 3.5 years (-0.35 [-0.40; -0.30], -0.15 [-0.20; -0.10] and - 0.18 [-0.23; -0.13], respectively). Infants introduced to pieces late were also more likely to be at risk for developmental delay according to DQ < 90 (OR [95%CI] = 1.62 [1.36; 1.94]).

Conclusions: This study shows that late introduction to food pieces (> 10 months) is related to lower neurodevelopmental scores. Given the challenges that complementary feeding may pose, concerted efforts are required to enhance our understanding of the sensory aspects of early diets and to ultimately provide guidance.

引入食物碎片的时间与神经发育:全国出生队列的研究结果。
背景:虽然辅食喂养具有挑战性,但人们很少关注食物质地/碎块的引入,尤其是在神经发育结果方面。本研究旨在确定婴儿期引入食物碎片的时间与幼儿期神经发育之间的关系。我们假设,较晚开始接触食物质地/碎片与不利的神经发育结果有关:在法国进行的全国性 ELFE(Étude Longitudinale Française depuis l'Enfance)出生队列调查中,我们从普通人群中招募了家庭(n = 18329),并选择了 8511 个家庭进行完整的病例分析。根据第一年的重复评估确定了开始接触食物碎片的年龄。使用有效工具对儿童的一系列神经发育结果进行了评估,即 1 岁和 3.5 岁时的综合评分,以及 2 岁时的语言习得评分。3.5岁时的发育迟缓风险是根据儿童的实际年龄和该年龄段的相应综合得分确定的,即发育商数(DQ)低于90。我们使用线性回归模型来评估开始接触食物的年龄与标准化神经发育评分之间的关系,同时根据发育迟缓的风险使用逻辑回归模型进行分析:我们的研究结果表明,婴儿较晚开始接触食物碎片(即 10 个月后,与较早(8 个月前)相比)与 1 岁、2 岁和 3.5 岁时较低的标准化神经发育评分(分别为-0.35 [-0.40; -0.30]、-0.15 [-0.20; -0.10]和-0.18 [-0.23; -0.13])之间存在一致的联系。根据 DQ,婴儿较晚才开始吃零食也更有可能出现发育迟缓:本研究表明,婴儿较晚(> 10 个月)开始添加辅食与较低的神经发育评分有关。鉴于辅食喂养可能带来的挑战,我们需要共同努力加强对早期饮食感官方面的了解,并最终提供指导。
