Child eating behaviours develop through interactions between the child's characteristics, psychological factors and the child's social environment and this affects the child's diet and weight. To examine the currently existing birth cohort studies examining child eating behaviours, a review was conducted. There are currently no birth cohorts that concurrently examine child eating behaviours, dietary intake, growth and parental feeding practices from birth into early childhood. Therefore, the primary objective of the Longitudinal Assessment of Children's Eating (LACE) study is to examine the bidirectional and transactional processes of child eating behaviours and parental feeding practices explaining poor dietary intake and excess weight across infancy and early childhood.
The LACE study will be a prospective, longitudinal parent-reported study following infants from younger than 4 months of age across nine waves of data collection: younger than 4 months, 4 months, 6 months, 9 months, 12 months, 18 months, 2 years, 3 years and 5 years. Participants will be included if they are parents of infants younger than 4 months, 18 years or older, fluent in English and living in Australia at baseline. A sample size of 1210 is proposed. Participants will be recruited online via paid social media (Facebook and Instagram) advertisements. The study will examine child eating behaviours, body mass index Z-score, dietary intake, screen time, temperament, parent feeding practices and styles, and demographics. The data will be obtained using the online survey software Qualtrics. Data analyses will be conducted using Stata.
Ethical approval was granted by the Deakin University Human Ethics Advisory Group, Faculty of Health (HEAG-H 120_2022). The findings from this study will be disseminated via presentations at scientific conferences and published manuscripts in peer-reviewed journals. Findings will be disseminated to the general public via mainstream media and to participants of the study with a summary of the findings.
儿童的进食行为是通过儿童的特征、心理因素以及儿童的社会环境之间的相互作用发展起来的，这会影响儿童的饮食和体重。为了研究目前现有的儿童进食行为队列研究，我们进行了一次综述。目前还没有同时从出生到幼儿期连续研究儿童进食行为、饮食摄入、生长和父母喂养行为的队列研究。因此，“儿童进食行为纵向评估（LACE）”研究的主要目的是研究儿童进食行为和父母喂养行为的双向和相互作用过程，以解释婴儿期和幼儿期不良饮食摄入和超重的原因。
LACE 研究将是一项前瞻性、纵向的父母报告研究，从 4 个月以下的婴儿开始，共进行 9 波数据收集：小于 4 个月、4 个月、6 个月、9 个月、12 个月、18 个月、2 岁、3 岁和 5 岁。如果父母是年龄在 18 岁以下或以上、能流利使用英语且在基线时居住在澳大利亚的 4 个月以下婴儿的父母，就可以参与该研究。计划招募 1210 名参与者。参与者将通过付费社交媒体（Facebook 和 Instagram）广告在线招募。该研究将从婴儿时期开始，一直持续到 5 岁，研究儿童进食行为、体重指数 Z 评分、饮食摄入、屏幕时间、气质、父母喂养行为和风格以及人口统计学等方面。使用在线调查软件 Qualtrics 收集数据。数据分析将使用 Stata 进行。
该研究已获得迪肯大学人类伦理咨询小组（Faculty of Health）的伦理批准（HEAG-H 120_2022）。该研究的结果将通过在科学会议上的演讲和在同行评议期刊上发表的论文进行传播。研究结果将通过主流媒体向公众传播，并向研究参与者提供研究结果摘要。
