Abstract：
Appetitive traits are associated with body weight. Increased understanding of how appetitive traits evolve from early life could advance research on obesity risk and inform intervention development. We report on tracking and age-related differences in appetitive traits in childhood within the RESONANCE cohort. Parents of RESONANCE children aged 6.02 ± 2.99 years completed the Child Eating Behavior Questionnaire (CEBQ). Pearson correlations of appetitive traits and age were tested for all participants contributing at least one observation, using each participant\'s first observation (N = 335). Children\'s first and second observations of the CEBQ (n = 127) were used to test tracking (paired correlations) and age-related differences (paired t-tests) within individuals. CEBQ correlations with age suggested that satiety responsiveness, slowness in eating, emotional undereating, and desire to drink decreased with age (r = -0.111 to r = -0.269, all p < 0.05), while emotional overeating increased with age (r = 0.207, p < 0.001). Food fussiness demonstrated a quadratic relationship with age. Paired t-tests further supported an increase in emotional overeating with age (M: 1.55 vs. 1.69, p = 0.005). All CEBQ subscales demonstrated moderate to high tracking (r = 0.533 to r = 0.760, p < 0.001). Our initial findings within the RESONANCE cohort suggest that food avoidant traits are negatively related with age, while emotional overeating increases with age, and that appetitive traits track through childhood.
摘要：
食欲性状与体重有关。增加对食欲特征如何从生命早期演变的理解可以促进肥胖风险的研究并为干预发展提供信息。我们报告了在RESONANCE队列中儿童食欲性状的跟踪和年龄相关差异。6.02±2.99岁的RESONANCE儿童的父母完成了儿童饮食行为问卷（CEBQ）。对所有参与者进行了至少一次观察，测试了食欲特征和年龄的Pearson相关性。使用每个参与者的第一次观察(N=335)。儿童对CEBQ的第一次和第二次观察结果（n=127）用于测试个体内的跟踪（配对相关性）和与年龄相关的差异（配对t检验）。CEBQ与年龄的相关性表明饱腹感反应，吃得很慢，情绪不足，并且饮酒欲望随着年龄的增长而下降（r=-0.111至r=-0.269，所有p<0.05），而情绪暴饮暴食随年龄增长而增加（r=0.207，p<0.001）。食物烦躁与年龄呈二次关系。配对t检验进一步支持情绪暴饮暴食随着年龄的增长而增加(M：1.55vs.1.69，p=0.005）。所有CEBQ分量表显示中度到高度跟踪（r=0.533至r=0.760，p<0.001）。我们在RESONANCE队列中的初步发现表明，避免食物的特征与年龄呈负相关，而情绪暴饮暴食随着年龄的增长而增加，这种食欲特征贯穿于童年。
