To compare the dietary intakes of Dutch nutrition and dietetics students with the Dutch RDA and the Dutch National Food Consumption Survey (DNFCS), and to assess whether dietary intake changes during education.
Cross-sectional and longitudinal research (2004-2010).
Data collection by 7 d dietary record and questionnaire.
Dutch nutrition and dietetics students.
Three hundred and fifty-two first-year and 216 fourth-year students were included. One hundred and thirty-three students in three cohorts were assessed twice. Of first-year students, >80 % met the RDA for all macronutrients. Of these students only 37 % met the RDA for fibre and in 43 % intake of saturated fat was too high. Fourth-year students more often met the RDA for fruits (55 %) and vegetables (74 %) compared with first-year students (32 % and 40 %, respectively). Intake of fruits and vegetables of both first- and fourth-year students was much higher than that of DNFCS participants (where 2 % and 7 %, respectively, met the corresponding RDA). Only <25 % of fourth-year students met the RDA for Fe, Se and vitamin D. In the cohorts, dietary intake for all macronutrients stabilised from the first to the fourth year (>80 %). Intakes of dietary fibre, Ca, Mg, Se, riboflavin, niacin, fruits, vegetables and fish improved significantly during education.
Dietary intake of nutrition and dietetics students is much better than that of DNFCS participants and improved during education. However, there is still a gap between actual dietary intake and the RDA, especially for Fe, Se and vitamin D.
比较荷兰营养与饮食专业学生的饮食摄入与荷兰推荐日摄入量(RDA)和荷兰国家食物消费调查(DNFCS),并评估教育过程中饮食摄入是否发生变化。
横断面和纵向研究(2004-2010 年)。
通过 7 天饮食记录和问卷收集数据。
荷兰营养与饮食专业学生。
纳入 352 名一年级学生和 216 名四年级学生。三个队列中有 133 名学生接受了两次评估。在一年级学生中,超过 80%的人满足了所有宏量营养素的 RDA。在这些学生中,只有 37%的人满足了纤维的 RDA,而 43%的人摄入的饱和脂肪过高。与一年级学生相比,四年级学生更常满足水果(55%)和蔬菜(74%)的 RDA。然而,与 DNFCS 参与者相比,一、四年级学生的水果和蔬菜摄入量都要高得多(分别为 2%和 7%满足相应的 RDA)。只有不到 25%的四年级学生满足铁、硒和维生素 D 的 RDA。在队列中,所有宏量营养素的饮食摄入量从第一年到第四年都稳定在 80%以上。膳食纤维、钙、镁、硒、核黄素、烟酸、水果、蔬菜和鱼类的摄入量在教育过程中显著改善。
营养与饮食专业学生的饮食摄入明显优于 DNFCS 参与者,且在教育过程中得到改善。然而,实际饮食摄入与 RDA 之间仍存在差距,尤其是铁、硒和维生素 D。
