To identify a posteriori dietary patterns among women planning pregnancy and assess the reproducibility of these patterns in a subsample using two dietary assessment methods.
A semi-quantitative FFQ was administered to women enrolled in the Singapore PREconception Study of long-Term maternal and child Outcomes study. Dietary patterns from the FFQ were identified using exploratory factor analysis (EFA). In a subsample of women (n 289), 3-d food diaries (3DFD) were also completed and analysed. Reproducibility of the identified patterns was assessed using confirmatory factor analysis (CFA) in the subsample, and goodness of fit of the CFA models was examined using several fit indices. Subsequently, EFA was conducted in the subsample and dietary patterns of the FFQ and the 3DFD were compared.
Singapore.
1007 women planning pregnancy (18-45 years).
Three dietary patterns were identified from the FFQ: the 'Fish, Poultry/Meat and Noodles' pattern was characterised by higher intakes of fish, poultry/meat and noodles in soup; 'Fast Food and Sweetened Beverages' pattern was characterised by higher intakes of fast food, sweetened beverages and fried snacks; 'Bread, Legumes and Dairy' pattern was characterised by higher intakes of buns/ethnic breads, nuts/legumes and dairy products. The comparative fit indices from the CFA models were 0·79 and 0·34 for the FFQ and 3DFD of the subsample, respectively. In the subsample, three similar patterns were identified in the FFQ while only two for the 3DFD.
Dietary patterns from the FFQ are reproducible within this cohort, providing a basis for future investigations on diet and health outcomes.
确定计划怀孕女性的后天饮食模式，并使用两种饮食评估方法在亚样本中评估这些模式的可重复性。
对参加新加坡妊娠前研究长期母婴结局研究的女性进行半定量食物频率问卷（FFQ）调查。使用探索性因子分析（EFA）从 FFQ 中确定饮食模式。在亚样本中（n=289），还完成了 3 天的饮食日记（3DFD）并进行了分析。在亚样本中使用验证性因子分析（CFA）评估确定模式的可重复性，并使用多个拟合指数检查 CFA 模型的拟合优度。随后，在亚样本中进行 EFA，并比较 FFQ 和 3DFD 的饮食模式。
新加坡。
1007 名计划怀孕的女性（18-45 岁）。
从 FFQ 中确定了三种饮食模式：“鱼、禽/肉和面条”模式的特点是摄入更多的鱼类、禽肉/肉类和汤中的面条；“快餐和甜饮料”模式的特点是摄入更多的快餐、甜饮料和炸零食；“面包、豆类和乳制品”模式的特点是摄入更多的面包卷/民族面包、坚果/豆类和乳制品。CFA 模型的比较拟合指数分别为亚样本中 FFQ 和 3DFD 的 0.79 和 0.34。在亚样本中，FFQ 中确定了三种类似的模式，而 3DFD 中仅确定了两种。
FFQ 中的饮食模式在该队列中具有可重复性，为未来关于饮食和健康结果的研究提供了基础。
