Dietary pattern analysis constitutes a suitable method for identifying complex food preferences as well as a useful tool for comparing dietary behaviour across individual populations. In addition to a lack of information on Central European dietary patterns, dietary data featuring a longitudinal aspect are likewise largely unavailable for the region. Our study thus strives to address this gap by analysing children's dietary patterns, their stability and possible changes at 7, 11 and 15 years in the Czech part of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC-CZ).
We analysed dietary data based on the self-reported semi-quantitative FFQ obtained in 1998, 2002 and 2006. Dietary patterns were derived using factor analysis for each period, followed by the determination of dietary pattern stability across the individual periods.
The analysis of dietary patterns was based on longitudinal children's dietary data from the geographical region that was undergoing massive socio-economic changes at the time of birth of the study subjects.
All participants were children. At 7 years the analysis included 3220 children, at 11 years the analysis included 2509 children and at 15 years the analysis included 1589 children.
Two stable children's dietary patterns labelled as 'prudent' and 'junk food' were identified across all three time points (7, 11 and 15 years).
This study identifies stable longitudinal trends in the dietary behaviour of children enrolled in the ELSPAC-CZ study.
饮食模式分析是一种识别复杂食物偏好的合适方法，也是比较不同人群饮食行为的有用工具。除了中欧饮食模式信息不足外，该地区也缺乏具有纵向特征的饮食数据。因此，我们的研究旨在通过分析捷克部分欧洲妊娠和儿童纵向研究（ELSPAC-CZ）中儿童的饮食模式、7、11 和 15 岁时的稳定性以及可能的变化来填补这一空白。
我们根据 1998 年、2002 年和 2006 年获得的自我报告半定量 FFQ 分析了饮食数据。使用因子分析为每个时期提取饮食模式，然后确定个体时期之间的饮食模式稳定性。
饮食模式分析基于当时正在经历大规模社会经济变革的地理区域的纵向儿童饮食数据。
所有参与者均为儿童。7 岁时的分析包括 3220 名儿童，11 岁时的分析包括 2509 名儿童，15 岁时的分析包括 1589 名儿童。
在所有三个时间点（7、11 和 15 岁）都确定了两种稳定的儿童饮食模式，分别标记为“谨慎”和“垃圾食品”。
本研究确定了 ELSPAC-CZ 研究中儿童饮食行为的稳定纵向趋势。
