目的：确定孕妇在妊娠三个月期间的主要饮食模式，并检查相关的营养摄入量。设计：参与者在怀孕的每个三个月完成一份3d食物日记。建立了36个食物组，并采用k-均值聚类分析得出饮食模式。地点：爱尔兰都柏林国家妇产医院。研究对象：285名年龄在20 - 41岁之间的健康孕妇。结果：在每个时间点确定了两种饮食模式。她们被标记为“不健康”（第143、150和155名分别在妊娠1、2和3个月）和“有健康意识”（第142、135和130名分别在妊娠1、2和3个月）。“健康意识强”组的妇女明显比“不健康”组的妇女年龄更大，体重指数更低，受教育程度更高。在妊娠早期“不健康”组（143例）中，103例（72.0%）持续这种饮食模式到妊娠2期，81例（56.6%）持续到妊娠3期。在妊娠1期的“健康意识”组（142例）中，95例（66.9%）在妊娠2期继续采用这种饮食模式，69例（48.6%）持续到妊娠3期。结论：聚类分析得出两个明确的饮食模式在每个怀孕阶段。了解产妇的饮食模式对于制定针对怀孕的饮食指南非常重要。确定怀孕早期有“不健康”饮食模式的妇女，为饮食干预提供了机会，这可能对孕产妇和婴儿健康产生积极影响。
Objective: To determine the main dietary patterns of pregnant women during each of the three trimesters of pregnancy and to examine associated nutrient intakes. Design: Participants completed a 3d food diary during each trimester of pregnancy. Thirty-six food groups were created and dietary patterns were derived using k-means cluster analysis. Setting: National Maternity Hospital, Dublin, Ireland. Subjects: Two hundred and eighty-five healthy pregnant women aged between 20 and 41 years. Results: Two dietary patterns were identified at each time point. They were labelled 'Unhealthy' (n 143, 150 and 155 at trimester 1, 2 and 3, respectively) and 'Health Conscious' (n 142, 135 and 130 at trimester 1, 2 and 3, respectively). Women in the 'Health Conscious' cluster were significantly older, had lower BMI and were higher educated than those in the 'Unhealthy' cluster. Of those in the 'Unhealthy' cluster in the first trimester (n 143), 103 (72.0%) continued in this dietary pattern into trimester 2 and eighty-one (56.6%) continued into trimester 3. Of those in the 'Health Conscious' cluster in trimester 1 (n 142), ninety-five (66.9%) continued in this dietary pattern into trimester 2 and sixty-nine (48.6%) continued into trimester 3. Conclusions: Cluster analysis produced two clearly defined dietary patterns at each stage of pregnancy. Knowledge of maternal dietary patterns is important for the development of pregnancy-specific dietary guidelines. Identifying women with an 'Unhealthy' dietary pattern in early pregnancy affords the opportunity for a dietary intervention which may positively impact both maternal and infant health.
