【摘要】：目的研究摄入来源于谷物的膳食纤维对肠道运动及症状的影响。方法检索国内外医学期刊2013年7月前公开发表的来源于谷物的膳食纤维对肠道运动及症状研究的随机对照试验,由2位研究者根据纳入与排除标准独立进行文献筛选、资料提取及质量评价,采用Rev Man 5.2软件进行Meta分析。结果 13个研究共739名观察对象纳入分析。Meta分析显示膳食纤维组与对照组相比排便频率增加(WMD=0.10,95%CI 0.02~0.18,P0.05)、肠道通过时间减少(WMD=-6.36,95%CI-11.53~-1.20,P0.05)、粪便湿重增加(WMD=51.52,95%CI31.00~72.04,P0.05)、且不增加胃肠道副反应(SMD=0.06,95%CI-0.04~0.16,P=0.267),采用符合方案集分析时,功能性肠道障碍症状缓解率增加(RR=1.20,95%CI 1.00~1.44,P=0.05),意向性分析时功能性肠道障碍症状缓解率无明显增加(RR=1.16,95%CI 0.95~1.41,P=0.14)。结论来源于谷物的膳食纤维对肠道运动具有促进作用,且不增加胃肠道副反应,但对功能性肠道障碍症状缓解作用不明确。
[Abstract]:Objective to study the effects of dietary fiber intake from cereals on intestinal motility and symptoms.Methods A randomized controlled trial on intestinal motility and symptoms of dietary fiber derived from cereals published in domestic and foreign medical journals before July 2013 was searched and selected by two researchers independently according to the inclusion and exclusion criteria.Data extraction and quality evaluation were analyzed by Rev Man 5.2 software.When analyzing with a consistent schema set, the,The remission rate of functional intestinal disorders was increased. The remission rate of functional intestinal disorders was not significantly increased by RRRN 1.20 ~ 95 CI 1.001.4 ~ (4) P0. 05% and RRN 1.1695 CI 0.95 ~ 1.41 ~ (-1) P ~ (0. 14) ~ 0. 14% in intentionality analysis.Conclusion the dietary fiber derived from cereals can promote intestinal motility and does not increase the side effects of gastrointestinal tract, but it is not clear to alleviate the symptoms of functional intestinal disorders.
