Abstract

BACKGROUND Food fussiness (FF) describes the tendency to eat a small range of foods, due to pickiness and/or reluctance to try new foods. A common behaviour during childhood, and a considerable cause of caregiver concern; its causes are poorly understood. This is the first twin study of genetic and environmental contributions to the developmental trajectory of FF from toddlerhood to early adolescence, and stability and change over time. METHODS Participants were from Gemini, a population-based British cohort of n = 4,804 twins born in 2007. Parents reported on FF using the Child Eating Behaviour Questionnaire 'FF' scale when children were 16 months (n = 3,854), 3 (n = 2,666), 5 (n = 2,098), 7 (n = 703), and 13 years old (n = 970). A mixed linear model examined the trajectory of FF, and a correlated factors twin model quantified genetic and environmental contributions to variation in and covariation between trajectory parameters. A longitudinal Cholesky twin model examined genetic and environmental influences on FF at each discrete age. RESULTS We modelled a single FF trajectory for all children, which was characterised by increases from 16 months to 7 years, followed by a slight decline from 7 to 13 years. All trajectory parameters were under strong genetic influence (>70%) that was largely shared, indicated by high genetic correlations. Discrete age analyses showed that genetic influence on FF increased significantly after toddlerhood (16 months: 60%, 95% CI: 53%-67%; 3 years: 83%; 81%-86%), with continuing genetic influence as indicated by significant genetic overlap across every age. Shared environmental influences were only significant during toddlerhood. Unique environmental influences explained 15%-26% of the variance over time, with some enduring influence from 5 years onwards. CONCLUSIONS Individual differences in FF were largely explained by genetic factors at all ages. Fussy eating also shows a significant proportion of environmental influence, especially in toddlerhood, and may, therefore, benefit from early interventions throughout childhood. Future work needs to refine the FF trajectory and explore specific trajectory classes.
从蹒跚学步到青春期早期挑食的天性和养育:双子座双胞胎队列的研究结果。
背景食物挑剔症(FF)是指由于挑食和/或不愿尝试新食物而倾向于只吃少量食物。这是儿童时期的一种常见行为,也是引起看护人担忧的一个重要原因;但人们对其成因却知之甚少。这是第一项关于遗传和环境对 FF 从幼儿期到青春期早期的发展轨迹的影响,以及随着时间推移的稳定性和变化的双胞胎研究。父母使用儿童饮食行为问卷 "FF "量表报告了孩子在16个月(n = 3,854)、3岁(n = 2,666)、5岁(n = 2,098)、7岁(n = 703)和13岁(n = 970)时的FF情况。混合线性模型检验了 FF 的轨迹,而相关因素双胞胎模型则量化了遗传和环境对轨迹参数变异和协变的贡献。结果我们为所有儿童建立了一个单一的FF轨迹模型,其特点是从16个月到7岁期间FF不断增加,然后从7岁到13岁期间FF略有下降。所有轨迹参数都受到很强的遗传影响(>70%),而且遗传相关性很高,表明遗传影响在很大程度上是共同的。离散年龄分析表明,遗传对 FF 的影响在幼儿期后显著增加(16 个月:60%,95% CI:53%-67%;3 岁:83%;81%-86%),每个年龄段都有显著的遗传重叠,表明遗传影响仍在继续。共同的环境影响仅在幼儿期具有显著性。随着时间的推移,独特的环境影响解释了 15%-26%的变异,从 5 岁开始有一些持久的影响。挑食在很大程度上也受到环境的影响,尤其是在幼儿期,因此,在整个儿童期进行早期干预可能会使其受益。未来的工作需要完善FF轨迹并探索特定的轨迹类别。

期刊介绍: The Journal of Child Psychology and Psychiatry (JCPP) is a highly regarded international publication that focuses on the fields of child and adolescent psychology and psychiatry. It is recognized for publishing top-tier, clinically relevant research across various disciplines related to these areas. JCPP has a broad global readership and covers a diverse range of topics, including: Epidemiology: Studies on the prevalence and distribution of mental health issues in children and adolescents. Diagnosis: Research on the identification and classification of childhood disorders. Treatments: Psychotherapeutic and psychopharmacological interventions for child and adolescent mental health. Behavior and Cognition: Studies on the behavioral and cognitive aspects of childhood disorders. Neuroscience and Neurobiology: Research on the neural and biological underpinnings of child mental health. Genetics: Genetic factors contributing to the development of childhood disorders. JCPP serves as a platform for integrating empirical research, clinical studies, and high-quality reviews from diverse perspectives, theoretical viewpoints, and disciplines. This interdisciplinary approach is a key feature of the journal, as it fosters a comprehensive understanding of child and adolescent mental health. The Journal of Child Psychology and Psychiatry is published 12 times a year and is affiliated with the Association for Child and Adolescent Mental Health (ACAMH), which supports the journal's mission to advance knowledge and practice in the field of child and adolescent mental health.
