The study aimed to document the dietary patterns of infants and determine the development of feeding difficulties as perceived by the mother according to the age at which lumpy solids were introduced into the diet.
Information was collected from a geographically representative population of 9360 mothers of infants born in 1991/92, part of the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC). Self-completion questionnaires enquiring about the foods and drinks consumed by the infant and any difficulties experienced by the mothers in feeding her child at both 6 months and 15 months of age were collected.
Infants were divided into three groups based on the age at which they were first introduced to 'lumpy' solids: 10.7% were introduced before 6 months of age, 71.7% were introduced between 6 and 9 months and 17.6% were introduced after 10 months of age. The foods eaten by those introduced before 6 months and after 10 months were compared to those introduced between 6 and 9 months. Behaviours and problems as reported by the mother were also assessed.
Those infants who were introduced to lumpy solids at the earliest ages consumed a greater variety of family foods at the age of 6 months, while those introduced at 10 months or later had been given fewer solids of all types by 6 months of age and at 15 months were significantly less likely to be having family foods when compared to those introduced between 6 and 9 months. At each age, those introduced late (10 months or older) to lumps were more difficult to feed and had more definite likes and dislikes.
A significant difference was observed in the variety of foods given to infants at both 6 and 15 months according to the age at which they began to have lumps in their food, and feeding difficulties were more likely to occur when lumps were introduced at or after 10 months of age.
本研究旨在记录婴儿的饮食模式，并根据向饮食中引入块状固体食物的年龄，确定母亲所感知到的喂养困难的发展情况。
从具有地理代表性的9360名1991/92年出生婴儿的母亲群体中收集信息，这些母亲是埃文亲子纵向研究（ALSPAC）的一部分。收集了自我填写的问卷，询问婴儿在6个月和15个月大时所食用的食物和饮料，以及母亲在喂养孩子时遇到的任何困难。
根据首次引入“块状”固体食物的年龄，将婴儿分为三组：10.7%在6个月前引入，71.7%在6至9个月之间引入，17.6%在10个月后引入。将6个月前和10个月后引入块状固体食物的婴儿所吃的食物，与6至9个月之间引入的婴儿所吃的食物进行比较。还评估了母亲报告的行为和问题。
最早引入块状固体食物的婴儿在6个月大时食用的家庭食物种类更多，而10个月或更晚引入的婴儿在6个月大时食用的各类固体食物较少，与6至9个月之间引入块状固体食物的婴儿相比，在15个月大时食用家庭食物的可能性显著降低。在每个年龄段，较晚（10个月或更大）引入块状固体食物的婴儿更难喂养，并且有更明确的喜好和厌恶。
根据婴儿开始食用块状食物的年龄，在6个月和15个月时给予婴儿的食物种类存在显著差异，并且在10个月及以后引入块状食物时更有可能出现喂养困难。
