Objectives The objective of this study was to describe the compliance to dietary fibre recommendations of the Swiss population and to investigate the association between dietary fibre intake and ultraprocessed food (UPF) consumption. Methods Data were obtained from the cross-sectional Swiss National Nutrition Survey menuCH . We summarised the sociodemographic, lifestyle and anthropometric parameters as well as dietary data collected with two 24-hour dietary recalls for the whole population and subgroups according to absolute and relative dietary fibre intake. We analysed the associations between dietary fibre intake and UPF consumption by fitting multinomial logistic regression models. Data were weighted according to the menuCH weighting strategy to achieve a representation of the Swiss population. Results Data obtained from 2057 adults were included in the analysis, of which 87% had a dietary fibre intake of <30 g/day. Participants with high UPF consumption had lower odds of being in the medium or high dietary fibre intake groups than participants with low UPF consumption. The odds of being in the medium or high dietary fibre intake groups decreased linearly across quartiles of UPF consumption ( p for trend ≤0.004). Conclusions Dietary fibre intake is insufficient in all population groups in Switzerland. UPF consumption is inversely and dose dependently associated with dietary fibre intake. To increase dietary fibre intake, public health measures should discourage UPF consumption and increase dietary fibre intake via unprocessed or minimally processed foods. Data may be obtained from a third party and are not publicly available. Data may be obtained from the Swiss Federal Food Safety and Veterinary Office.

瑞士普通人群的膳食纤维摄入量及其与超加工食品消费的关系：基于人群的横断面国家营养调查分析


目的 本研究的目的是描述瑞士人口对膳食纤维建议的遵守情况，并调查膳食纤维摄入量与超加工食品 (UPF) 消费之间的关联。方法 数据来自瑞士国家营养调查横断面菜单CH。我们根据绝对和相对膳食纤维摄入量，总结了整个人群和亚组的社会人口统计学、生活方式和人体测量参数以及通过两次 24 小时饮食回顾收集的饮食数据。我们通过拟合多项逻辑回归模型分析了膳食纤维摄入量和 UPF 消耗量之间的关联。根据 menuCH 加权策略对数据进行加权，以代表瑞士人口。结果 分析纳入了 2057 名成年人的数据，其中 87% 的膳食纤维摄入量<30 克/天。与 UPF 消耗量低的参与者相比，UPF 消耗量高的参与者属于中等或高膳食纤维摄入量组的几率较低。处于中等或高膳食纤维摄入量组的几率在 UPF 摄入量的四分位数中呈线性下降（趋势 p ≤0.004）。结论 瑞士所有人群的膳食纤维摄入量均不足。 UPF 的消耗量与膳食纤维的摄入量成反比且呈剂量依赖性。为了增加膳食纤维的摄入量，公共卫生措施应阻止 UPF 的消费，并通过未加工或最低限度加工的食品增加膳食纤维的摄入量。数据可能从第三方获得，并且不公开。数据可从瑞士联邦食品安全和兽医办公室获得。
