High intake of dietary fibres has been associated with a reduced risk of DD. However, reports on which type of dietary fibre intake that is most beneficial have been conflicting. The aim of this study was to investigate the association between different dietary fibres and hospitalisation due to diverticular disease (DD) of the colon.
This was a major cohort study. The Swedish Mammography Cohort and the Cohort of Swedish Men were linked to the Swedish Inpatient Register and the Causes of Death Register. Data on the intake of dietary fibre were collected through questionnaires. The effect of intake (in quartiles) of different types of dietary fibre on the incidence of hospitalisation due to DD was investigated using multivariable Cox regression. Estimates were adjusted according to age, BMI, physical activity, co-morbidity, intake of corticosteroids, smoking, alcohol intake and education level.
Women with intake of fruit and vegetable fibres in the highest quartile (median 12.6 g/day) had a 30% decreased risk of hospitalisation compared to those with the lowest intake (4.1 g/day). Men within the highest quartile (10.3 g/day) had a 32% decreased risk compared to those with a low intake (2.9 g/day). High intake of fibres from cereals did not affect the risk.
A high intake of fruits and vegetables may reduce the risk of hospitalisation due to DD. Intake of cereals did not influence the risk.
高膳食纤维摄入量与 DD 风险降低有关。然而，关于哪种膳食纤维摄入量最有益的报告一直存在争议。本研究旨在探讨不同膳食纤维与因结肠憩室病（DD）住院之间的关系。
这是一项主要的队列研究。瑞典乳腺摄影队列和瑞典男性队列与瑞典住院患者登记处和死因登记处相关联。膳食纤维摄入量的数据通过问卷收集。使用多变量 Cox 回归分析不同类型膳食纤维摄入量（按四分位数）与因 DD 住院的发生率之间的关系。根据年龄、BMI、身体活动、合并症、皮质激素摄入量、吸烟、饮酒量和教育水平进行调整。
膳食纤维摄入量最高的四分位数（中位数 12.6g/天）的女性与膳食纤维摄入量最低的四分位数（4.1g/天）相比，住院风险降低 30%。膳食纤维摄入量最高的四分位数（10.3g/天）的男性与摄入量低的四分位数（2.9g/天）相比，住院风险降低 32%。谷物纤维的高摄入量不会影响风险。
高膳食纤维摄入量可能会降低因 DD 住院的风险。谷物纤维的摄入量不会影响风险。
