背景与目的：无症状憩室病通常归因于低纤维饮食引起的便秘，尽管这种机制的证据有限。我们研究了便秘和低膳食纤维摄入量与无症状憩室病风险之间的关联。方法：我们进行了一项横断面研究，分析了539例憩室病患者和1569例无憩室病患者（对照组）的数据。参与者接受了结肠镜检查和饮食，体力活动和排便习惯的评估。我们的分析仅限于参与者不知道他们的憩室病，以减少风险的偏倚respons.RESULTS：concernation是不相关的憩室病的风险增加。排便次数较少的受试者（
BACKGROUND & AIMS: Asymptomatic diverticulosis is commonly attributed to constipation caused by a low-fiber diet, although evidence for this mechanism is limited. We examined the associations between constipation and low dietary fiber intake with risk of asymptomatic diverticulosis.METHODS: We performed a cross-sectional study that analyzed data from 539 individuals with diverticulosis and 1569 without (controls). Participants underwent colonoscopy and assessment of diet, physical activity, and bowel habits. Our analysis was limited to participants with no knowledge of their diverticular disease to reduce the risk of biased responses.RESULTS: Constipation was not associated with an increased risk of diverticulosis. Participants with less frequent bowel movements (
