目的：研究儿童在整个童年时期不同时间点的饮食模式与估计营养摄入量的关系。设计：3、4、7 和 9 岁时的 FFQ 由母亲完成。使用主成分分析横断面确定饮食模式；一致获得“加工”、“健康意识”和“传统”模式。计算模式得分与营养素摄入量之间的相关性以及由模式解释的营养素方差比例。地点：雅芳父母和儿童纵向研究 (ALSPAC)，英国布里斯托尔。受试者：儿童提供 3 至 9 岁之间的数据（n 8010 至 10 023）。结果：饮食模式解释了大多数营养素绝对摄入量方差的很大比例（3 岁时>25%， >40% 其他年龄）。能量调整后，蛋白质、纤维、钾、镁、铁、锌、叶酸、硫胺素和维生素B-6继续得到很好的解释。在“加工”模式和常量营养素之间观察到很强的相关性，包括能量（r = 0.481-0.619）、总脂肪（r = 0.529-0.662）和总糖（r = 0.475-0.693）。然而，在能量调整后，与大多数微量营养素的相关性发生了逆转，这表明“加工”模式能量密集但营养贫乏。无论能量是否调整，“健康意识”和“传统”模式与蛋白质、纤维和大多数微量营养素呈强烈正相关。这些模式的得分越高，营养成分越好。结论：饮食模式解释了饮食营养成分的合理变化。 “健康意识”和“传统”饮食模式得分越高，营养成分越好；相反，“加工”模式得分越高，营养成分越差。
Objective: To examine how the dietary patterns of children at various time points throughout childhood relate to estimated nutrient intakes.Design: FFQ at 3, 4, 7 and 9 years of age were completed by mothers. Dietary patterns were identified cross-sectionally using principal component analysis; 'processed', 'health conscious' and 'traditional' patterns were consistently obtained. Correlations between pattern scores and nutrient intakes and proportions of variance in nutrients explained by the patterns were calculated.Setting: Avon Longitudinal Study of Parents and Children (ALSPAC), Bristol, UK.Subjects: Children provided data between 3 and 9 years of age (n 8010 to 10 023).Results: Dietary patterns explained substantial proportions of the variance of the absolute intake for most nutrients (>25% at 3 years of age, >40% other ages). After energy adjustment, protein, fibre, K, Mg, Fe, Zn, folate, thiamin and vitamin B-6 continued to be well explained. Strong correlations were observed between the 'processed' pattern and macronutrients including energy (r = 0.481-0.619), total fat (r = 0.529-0.662) and total sugar (r = 0.475-0.693). However correlations with most micronutrients were reversed after energy adjustment, suggesting that the 'processed' pattern is energy-dense but nutrient-poor. The 'health conscious' and 'traditional' patterns were strongly positively correlated with protein, fibre and most micronutrients, whether energy adjusted or not. Higher scores on these patterns were associated with a better nutrient profile.Conclusions: Dietary patterns explain a reasonable amount of the variation in the nutrient content of diets. Higher scores on the 'health conscious' and 'traditional' dietary patterns were related to better nutrient profiles; conversely, with higher scores on the 'processed' pattern the nutrient profile was poorer.
