Maternal diet is critical to fetal development and lifelong health outcomes. In this context, dietary quality indices in pregnancy should be explicitly underpinned by data correlating food intake patterns with nutrient intakes known to be important for gestation.
Our aim was to assess the correlation between dietary quality scores derived from a novel online dietary assessment tool (DAT) and nutrient intake data derived from the previously validated Willett Food Frequency Questionnaire (WFFQ).
524 women completed the validated semi-quantitive WFFQ and online DAT questionnaire in their first trimester. Spearman correlation and Kruskal-Wallis tests were used to test associations between energy-adjusted and energy-unadjusted nutrient intakes derived from the WFFQ, and diet and nutrition scores obtained from the DAT.
Positive correlations were observed between respondents' diet and nutrition scores derived from the online DAT, and their folate, vitamin B12, iron, calcium, zinc and iodine intakes/MJ of energy consumed derived from the WFFQ (all P < 0.001). Negative correlations were observed between participants' diet and nutrition scores and their total energy intake (P = 0.02), and their percentage energy from fat, saturated fat, and non-milk extrinsic sugars (NMES) (all P ≤ 0.001). Median dietary fibre, beta carotene, folate, vitamin C and vitamin D intakes derived from the WFFQ, generally increased across quartiles of diet and nutrition score (all P < 0.001).
Scores generated by this web-based DAT correlate with important nutrient intakes in pregnancy, supporting its use in estimating overall dietary quality among obstetric populations.
孕产妇饮食对胎儿发育和终身健康结局至关重要。在此背景下，孕期饮食质量指标应以将食物摄入模式与已知对妊娠重要的营养素摄入量相关联的数据为明确依据。
我们的目的是评估源自一种新型在线饮食评估工具（DAT）的饮食质量得分与源自先前验证过的威尔特食物频率问卷（WFFQ）的营养素摄入数据之间的相关性。
524名女性在孕早期完成了经过验证的半定量WFFQ和在线DAT问卷。使用Spearman相关性检验和Kruskal-Wallis检验来测试源自WFFQ的能量调整和未调整的营养素摄入量与从DAT获得的饮食和营养得分之间的关联。
观察到，受访者从在线DAT得出的饮食和营养得分与他们从WFFQ得出的每兆焦耳能量消耗中的叶酸、维生素B12、铁、钙、锌和碘摄入量之间呈正相关（所有P < 0.001）。观察到参与者的饮食和营养得分与他们的总能量摄入量（P = 0.02）以及来自脂肪、饱和脂肪和非乳外源性糖（NMES）的能量百分比之间呈负相关（所有P≤0.001）。从WFFQ得出的膳食纤维、β-胡萝卜素、叶酸、维生素C和维生素D的中位数摄入量，通常随着饮食和营养得分的四分位数增加而增加（所有P < 0.001）。
这种基于网络的DAT生成的得分与孕期重要营养素摄入量相关，支持其用于估计产科人群的总体饮食质量。
