The role of nutrition in health and disease is well established. However, more research on this topic is needed to fill gaps in our current knowledge. The Lifelines cohort study, a large Dutch prospective cohort study, was established as a resource for international researchers, aiming to obtain insight into the aetiology of healthy ageing. The study started with 167,729 participants, covering three generations, aiming to follow them for thirty years. This article describes the habitual dietary intake, assessed using the Flower Food Frequency Questionnaire (FFQ), among Lifelines cohort study participants at baseline, stratified by sex and different categories of age, socioeconomic status (SES) and body mass index (BMI). A total of 59,982 adults (23,703 men and 36,279 women), who completed the Flower FFQ and reported plausible habitual dietary intake, were included in the analyses. Median daily energy intake was higher in men (2368 kcal) than in women (1848 kcal), as well as macronutrient intake. Energy and macronutrient intake decreased with increasing age and BMI categories; no differences were observed between SES categories. Intake of most micronutrients was higher in men than in women. Differences were observed between age categories, but not between SES and BMI categories. Food groups were consumed in different amounts by men and women; differences between age, SES and BMI categories were observed as well. The Lifelines cohort study provides extensive dietary intake data, which are generalisable to the general Dutch population. As such, highly valuable dietary intake data are available to study associations between dietary intake and the development of chronic diseases and healthy aging.
营养在健康和疾病中的作用已得到充分证实。然而，为了填补我们现有知识的空白，还需要对这一主题进行更多的研究。莱顿生命线队列研究是一项大型的荷兰前瞻性队列研究，旨在为国际研究人员提供资源，以深入了解健康衰老的病因。该研究最初纳入了 167729 名参与者，涵盖了三代人，旨在对他们进行 30 年的随访。本文描述了莱顿生命线队列研究参与者在基线时的习惯性饮食摄入情况，使用了花型食物频率问卷（FFQ）进行评估，并按性别和不同年龄段、社会经济地位（SES）和身体质量指数（BMI）进行了分层。共有 59982 名成年人（23703 名男性和 36279 名女性）完成了花型 FFQ，并报告了合理的习惯性饮食摄入情况，这些人被纳入了分析。男性的日均能量摄入（2368 千卡）高于女性（1848 千卡），以及宏量营养素摄入。能量和宏量营养素的摄入量随着年龄和 BMI 类别的增加而降低；在 SES 类别之间没有观察到差异。大多数微量营养素的摄入量在男性中高于女性。在年龄类别之间观察到差异，但在 SES 和 BMI 类别之间没有观察到差异。男性和女性的食物摄入量不同；在年龄、SES 和 BMI 类别之间也观察到了差异。莱顿生命线队列研究提供了广泛的饮食摄入数据，这些数据可推广到荷兰一般人群。因此，研究饮食摄入与慢性疾病和健康老龄化发展之间的关系时，可获得非常有价值的饮食摄入数据。
