The effectiveness of colonoscopy is highly dependent on the quality of bowel preparation. Although many studies have previously evaluated the role of cleansing methods and dosing regimens, few have examined the association between bowel habits and subsequent bowel preparation. Here, we aimed to evaluate the impact of bowel habits on the quality of bowel preparation.A total of 404 patients who underwent a total colonoscopy and completed a personal bowel habit questionnaire at Korea University Hospital between December 2012 and December 2013 were enrolled. The usual stool form of patients was classified into 7 categories according to the Bristol Stool Scale (BSS). The quality of bowel preparation was determined during colonoscopy according to the Ottawa Bowel Preparation Scale (OBPS). Segment scores of ≥3 or total OBPS scores of >7 were defined as poor bowel preparation.Poor bowel preparation was reported in 9.4% of observed colonoscopies. The odds ratio (OR) of poor bowel preparation being associated with infrequent bowel movements (<3/week) was 5.00 (95% confidence interval [CI], 1.91-13.1, P = .001). BSS types 1 and 2 tended to have an association with poor bowel preparation, but the association was statistically insignificant (OR: 2.38; 95% CI, 0.90-6.33, P = .082). After adjusting for age, sex, drinking, presence of diabetes mellitus, and bowel preparation regimen, infrequent bowel movement (<3/week) was still significantly associated with poor bowel preparation. When subdividing by colonic segment, it was significantly associated with poor bowel preparation in all segments.Infrequent bowel movement (<3/week) was significantly associated with poor bowel preparation.
结肠镜检查的有效性高度依赖于肠道准备的质量。尽管此前许多研究评估了清洁方法和给药方案的作用，但很少有研究探讨排便习惯与后续肠道准备之间的关联。在此，我们旨在评估排便习惯对肠道准备质量的影响。
2012年12月至2013年12月期间，在韩国大学医院接受全结肠镜检查并完成个人排便习惯问卷的404例患者被纳入研究。根据布里斯托大便分类法（BSS），将患者的常规粪便形态分为7类。根据渥太华肠道准备量表（OBPS）在结肠镜检查期间确定肠道准备质量。节段评分≥3或OBPS总分>7被定义为肠道准备不佳。
在观察到的结肠镜检查中，9.4%报告肠道准备不佳。肠道准备不佳与排便次数少（<3次/周）相关的优势比（OR）为5.00（95%置信区间[CI]，1.91 - 13.1，P = 0.001）。BSS 1型和2型往往与肠道准备不佳有关，但该关联无统计学意义（OR：2.38；95%CI，0.90 - 6.33，P = 0.082）。在调整年龄、性别、饮酒、糖尿病的存在和肠道准备方案后，排便次数少（<3次/周）仍与肠道准备不佳显著相关。按结肠节段细分时，在所有节段中均与肠道准备不佳显著相关。
排便次数少（<3次/周）与肠道准备不佳显著相关。
