Infants become increasingly exposed to sweet-tasting foods in their first year of life. However, it is still unclear whether repeated exposure to sweet taste is linked to infants' sweetness liking during this period. Making use of data from the OPALINE cohort, this study aimed to examine the link between sweetness exposure and sweetness liking during two important periods in early infant feeding: at the start of complementary feeding (3-6 months) and the transition to the family table (10-12 months). Infants' sweetness exposure was assessed using 7-d food records which were completed by mothers every month ( 312), reporting daily consumption rates of formula/breast milk or complementary food and the type of formula milk and/or complementary foods for each feeding occasion. Infants' sweetness liking was studied in the laboratory at 3, 6 and 12 months of age by assessing their response to a lactose-water solution and the amount drunk of this solution compared with plain water. Linear regressions and structural equation model assessed associations between exposure to and liking for sweetness at 6 and 12 months. Neither at 6 ( 182) nor at 12 months ( 197) was sweetness exposure associated with sweetness liking. While sweetness liking at 3 months was unrelated to liking at 6 months, the latter predicted sweetness liking at 12 months. These findings demonstrate no association between sweetness exposure at 3 to 12 months and liking at 6 and 12 months despite a sharp increase in sweetness exposure in that period. However, sweetness liking at 6 and 12 months was positively associated.
婴儿在出生后的第一年里接触甜味食物的机会越来越多。然而，在此期间，反复接触甜味是否与婴儿对甜味的喜好有关仍不清楚。本研究利用OPALINE队列研究的数据，旨在探讨在婴儿早期喂养的两个重要阶段——开始添加辅食（3至6个月）和过渡到家庭餐桌饮食（10至12个月）——甜味接触与甜味喜好之间的联系。通过母亲每月填写的7天饮食记录（共312份）来评估婴儿的甜味接触情况，记录每次喂养时配方奶/母乳或辅食的每日食用量，以及配方奶和/或辅食的类型。在婴儿3个月、6个月和12个月大时，在实验室中通过评估他们对乳糖水溶液的反应以及与白开水相比该溶液的饮用量，来研究婴儿对甜味的喜好。线性回归和结构方程模型评估了6个月和12个月时甜味接触与甜味喜好之间的关联。在6个月大时（共182名婴儿）和12个月大时（共197名婴儿），甜味接触均与甜味喜好无关。虽然3个月大时对甜味的喜好与6个月大时的喜好无关，但6个月大时对甜味的喜好可预测12个月大时的甜味喜好。这些研究结果表明，尽管在3至12个月期间甜味接触急剧增加，但该期间的甜味接触与6个月和12个月时的甜味喜好之间并无关联。然而，6个月和12个月时的甜味喜好呈正相关。
