BACKGROUND
Most children have periods in their life where they reject familiar as well as non-familiar food items and this is often referred to as pickiness. The consequences of pickiness may be malnutrition and, if prolonged, potentially lower body weight. However, studies investigating the consequence of pickiness on subsequent changes in diet intake and weight are limited.
OBJECTIVES
To examine whether pickiness influences body mass index as well as diet intake over subsequent 15 months among obesity prone normal weight children aged 2-6 years.
METHODS
Data was obtained from the "Healthy Start" intervention study which included 271 children aged 2-6 years susceptible to overweight later in life. Information on pickiness was obtained from a parental questionnaire. Dietary habits were collected by 4-day dietary records filled in by the parents and height and weight were measured by trained health professionals and both measured twice over a 15 month period. Linear regression models were performed to assess the influence of pickiness on body mass index and diet with adjustments for possible confounders.
RESULTS
No differences in mean BMI Z-score were seen between picky/non-picky (P = 0.68) and little picky/non-picky (P = 0.68) children at 15 month follow-up. Picky children had a lower intake of protein (P = 0.01) than non-picky children despite no differences in total energy intake (P = 0.74), or in the other macronutrients, or the intake of fruit and vegetables, though children being a little picky had a lower intake of starch compared to non-picky children (P = 0.05). Results were essentially similar before and after adjustment for key covariates.
CONCLUSION
Our study showed that BMI Z-score after 15 months follow-up was similar for picky and non-picky children. Picky children seemed to develop a lower protein intake despite similar total energy intake and diet composition.
背景
大多数儿童在其生活中都有拒绝熟悉和不熟悉食物的时期，这通常被称为挑食。挑食的后果可能是营养不良，如果持续时间较长，可能会导致体重下降。然而，关于挑食对随后饮食摄入量和体重变化影响的研究有限。
目的
研究2至6岁易肥胖的正常体重儿童的挑食是否会在随后15个月内影响体重指数和饮食摄入量。
方法
数据来自“健康起步”干预研究，该研究包括271名2至6岁、日后易超重的儿童。挑食信息来自家长问卷。饮食习惯通过家长填写的4天饮食记录收集，身高和体重由训练有素的健康专业人员测量，在15个月内均测量两次。采用线性回归模型评估挑食对体重指数和饮食的影响，并对可能的混杂因素进行调整。
结果
在15个月的随访中，挑食/不挑食儿童（P = 0.68）和轻度挑食/不挑食儿童（P = 0.68）的平均BMI Z评分没有差异。尽管总能量摄入量没有差异（P = 0.74），其他宏量营养素或水果和蔬菜的摄入量也没有差异，但挑食儿童的蛋白质摄入量低于不挑食儿童（P = 0.01），不过轻度挑食儿童的淀粉摄入量低于不挑食儿童（P = 0.05）。在对关键协变量进行调整前后，结果基本相似。
结论
我们的研究表明，随访15个月后，挑食儿童和不挑食儿童的BMI Z评分相似。尽管总能量摄入量和饮食组成相似，但挑食儿童的蛋白质摄入量似乎较低。
