We aimed to compare the dietary quality and intake of pregnant women, women planning to conceive and women of childbearing age. Fifty-five pregnant women were matched for age and pre-pregnancy body mass index with 55 women planning to conceive and 55 women of childbearing age. Three Web-based 24-h recalls were completed, from which the Canadian Healthy Eating Index was calculated. Pregnant women had greater overall diet quality scores (66.8 ± 10.7, 60.3 ± 14.1 and 61.4 ± 12.8, in pregnant vs. planning to conceive and childbearing age women, p = .009), explained by a higher intake in fruits, vegetables and grain products and lower intake of foods that are high in fat, sugar or salt. Energy intake was significantly higher in pregnant versus planning to conceive women only (2283 ± 518 vs. 2062 ± 430 kcal, p = .03). Diet quality was greater among pregnant women, but diet quality scores were low in all groups, indicating that healthier dietary behaviours should be encouraged for all childbearing age women.

我们旨在比较孕妇，计划怀孕的妇女和育龄妇女的饮食质量和摄入量。55名孕妇的年龄和孕前体重指数匹配，其中55名计划怀孕的妇女和55名育龄妇女。完成了三个基于网络的24小时召回，从中计算了加拿大健康饮食指数。孕妇的总体饮食质量得分较高（孕妇与计划生育和育龄妇女的总体饮食质量得分（66.8±10.7、60.3±14.1和61.4±12.8  ），p = .009），这是因为水果，蔬菜和谷物的摄入量较高产品并减少高脂肪，高糖或高盐食物的摄入。与仅计划生育女性相比，孕妇的能量摄入量明显更高（2283±518与2062±430 kcal，p  = .03）。孕妇的饮食质量较高，但所有组的饮食质量得分均较低，这表明所有育龄妇女均应鼓励健康的饮食行为。
